Detailed ways

As can be seen from the background art, as people's demands for lighting continue to expand, higher requirements are also put forward for lighting effects.

In order to solve the technical problem, an embodiment of the present invention provides a light source module, which includes at least one multi-channel light-emitting unit. According to the light-emitting channel, each of the multi-channel light-emitting units includes a variety of individually controlled LED light sources, and according to the light-emitting channel Spectral peak wavelength, the LED light source includes at least a first monochromatic LED light source with a first spectral peak wavelength, a second monochromatic LED light source with a second spectral peak wavelength, and a third monochromatic LED with a third spectral peak wavelength A light source, and a first composite light LED light source having at least a fourth spectral peak wavelength; wherein, the spectral wavelength range of visible light includes a first spectral interval, a third spectral interval, and between the first spectral interval and the third spectral interval a second spectral interval between, the first spectral peak wavelength, the second spectral peak wavelength and the third spectral peak wavelength are respectively located in the first spectral interval, the second spectral interval and the third spectral interval, the fourth spectral peak wavelength The spectral peak wavelength is different from the first spectral peak wavelength, the second spectral peak wavelength and the third spectral peak wavelength; the first composite light LED light source is a non-white light source, and the spectrum of the first composite light LED light source is The color coordinates are located in the upper region of the Planck blackbody radiation curve in the CIE1931-xy chromaticity diagram.

The embodiment of the present utility model selects three kinds of monochromatic LED light sources located in different spectral ranges from the entire visible light wavelength range to meet the spectral requirements of short wavelength, medium wavelength and long wavelength respectively, and also selects different peak wavelengths. The first compound light LED light source is a non-white light source. The spectrum of the first compound light LED light source covers a large range of visible light spectral bands. The first compound light LED light source can be used as the basis for light mixing, so as to meet the requirements of short wavelengths. , medium-wavelength and long-wavelength monochromatic LED light sources, it is easy to obtain a larger and more continuous spectral adjustment range, so that a variety of tunable spectra can be realized, that is, light environments with different spectra can be realized, and, due to the first composite light The spectral color coordinates of the LED light source are located in the upper region of the Planck black body radiation curve in the CIE1931-xy chromaticity diagram.

Large color gamut range, and the color coordinates can be adjusted within the color gamut range. At the same time, because the spectral energy distribution of the four non-white LED light sources covers a large and continuous visible light spectral wavelength range, the adjustment accuracy is high , through the light mixing, a relatively continuous change in the spectral energy distribution can be achieved, and in addition, the adjustment of spectral indicators such as the color rendering index can be achieved within a wide range, so that the light source module is compatible with more functions (for example, applicable For the spectral adjustment system, under a set of fixed hardware conditions, light environments with different spectra can be realized), which can meet various lighting requirements (for example, high color rendering requirements of lighting, different rhythmic effect stimulation intensity requirements, and many a combination of lighting metrics requirements) to improve lighting performance and user experience.

In order to make the above objects, features and advantages of the embodiments of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 , FIG. 1 is a schematic structural diagram of an embodiment of a light source module of the present invention.

The light source module 10 includes at least one multi-channel light-emitting unit 20. According to the light-emitting channel, each of the multi-channel light-emitting units 20 includes a variety of individually controlled LED light sources 20L, and according to the spectral peak wavelength, the LED light source 20L includes: A first monochromatic LED light source 20a having a first spectral peak wavelength, a second monochromatic LED light source 20b having a second spectral peak wavelength, a third monochromatic LED light source 20c having a third spectral peak wavelength, and at least a fourth The first composite light LED light source 20d of the spectral peak wavelength.

Wherein, in the light-emitting unit 20, each LED light source 20L is used for emitting visible light, and the spectral wavelength range of the visible light has three intervals, including a first spectral interval, a third spectral interval, and those located in the first spectral interval and the third spectral interval. a second spectral interval between the three spectral intervals, the first spectral peak wavelength, the second spectral peak wavelength and the third spectral peak wavelength are located in the first spectral interval, the second spectral interval and the third spectral interval, respectively, The fourth spectral peak wavelength is different from the first spectral peak wavelength, the second spectral peak wavelength and the third spectral peak wavelength; the first composite light LED light source 20d is a non-white light source, and the first composite light source The spectral color coordinates of the light LED light source 20d are located in the upper region of the Planck blackbody radiation curve L (shown in FIG. 2 ) in the CIE1931-xy Chromaticity Diagram (CIE x-y Chromaticity Diagram). Here, the chromaticity diagram is a two-dimensional image coordinate system in which points at different positions represent the chromaticity information of various light sources. .

It should be noted that the spectral wavelength range of visible light of the human eye is about 380 to 780 nm. Here, the spectral wavelength range of the visible light is divided into three intervals, which are a first spectral interval, a third spectral interval, and a second spectral interval located between the first spectral interval and the third spectral interval, so The wavelengths of the first spectral interval, the second spectral interval and the third spectral interval increase in sequence.

In this embodiment, by making the first spectral peak wavelength, the second spectral peak wavelength and the third spectral peak wavelength respectively located in the first spectral range, the second spectral range and the third spectral range, that is to say, from the three The first monochromatic LED light source 20a, the second monochromatic LED light source 20b, and the third monochromatic LED light source 20c are respectively selected from different spectral ranges, so that in the spectral wavelength range of visible light, the short wavelength band, the middle wavelength band and the The spectral requirements of the long wavelength band are to cover a large color gamut range with a small number of light sources, and to achieve adjustable color coordinates within the color gamut range.

Specifically, the peak wavelength range of the first spectral range is 380 nm to 480 nm, the peak wavelength range of the third spectral range is 610 nm to 780 nm, and the peak wavelength of the second spectral range is between 480 nm and 610 nm. Among them, 380nm to 480nm is the spectral range of the short wavelength band of visible light (mainly emits blue light), 610nm to 780nm is the spectral range of the long wavelength band of visible light (mainly emits red light), and the range between 480nm and 610nm is the spectral range of the middle wavelength band of visible light ( It mainly emits yellow-green light), 380nm to 480nm is the lower left corner area of the horseshoe-shaped color gamut range (that is, the color coordinate range) in the CIE1931-xy chromaticity diagram, and 610nm to 780nm is the horseshoe-shaped color gamut range in the CIE1931-xy chromaticity diagram (that is, The right area of the color coordinate range), so it is beneficial to cover a large color gamut range, and the color coordinate can be adjusted within the color gamut range.

The light source module 10 includes at least one multi-channel light-emitting unit 20, and the LED light source 20L that can be controlled independently serves as an independent light-emitting channel. Specifically, the first single-color LED light source 20a, the second single-color LED light source 20b, the third single-color LED light source 20c, and the first composite light LED light source 20d correspond to one light-emitting channel respectively, so as to obtain a light source module having at least four channels 10. Correspondingly, according to the light mixing mode of the LED light source 20L, the light source module 10 is configured to emit light formed by a single LED light source 20L or light formed by mixing light from a plurality of LED light sources 20L.

The LED light source 20L has the characteristics of energy saving, environmental protection, safety, long life, low power consumption, high efficiency, high brightness, waterproof, and miniature. Moreover, the LED light source 20L also has the characteristics of free spectral combination and easy adjustment of luminous intensity. The light source 20L can be easily selected to emit light of a suitable color or peak wavelength, so that the light source module 10 can emit light that meets the lighting requirements.

In this embodiment, the LED light sources 20L all include LED chips. As an example, the LED chips may be mounted on the circuit board 30 by surface mounting or COB (chip on board, chip-on-board) packaging. As an example, the circuit board 30 is a printed circuit board (Printed Circuit Board, PCB). Specifically, according to the actual situation (for example, according to the number and arrangement of the LED light sources 20L, or the type of lamps used by the light source module 10 ), the shape of the circuit board 30 includes a square, a rectangle, a regular polygon or a circle. As shown in FIG. 1 , the shape of the circuit board 30 is shown as a square.

In this embodiment, the spectral peak wavelengths of the first monochromatic LED light source 20a, the second monochromatic LED light source 20b and the third monochromatic LED light source 20c are located in the first spectral interval, the second spectral interval and the third spectral interval, respectively, That is to say, three monochromatic LED light sources were selected from the entire visible light spectral wavelength range to meet the spectral requirements of the short wavelength band, the medium wavelength band and the long wavelength band respectively, and three monochromatic LED light sources were also selected. The peak wavelengths of the light sources are different and the first composite light LED light source 20d is a non-white light source. The spectrum of the first composite light LED light source 20d covers a large visible light spectral band range, and the first composite light LED light source 20d can be used as a light mixing device. It is easy to obtain a larger and more continuous spectrum adjustment range, so that a variety of tunable spectrum can be realized, that is, it is possible to achieve different spectrums. Moreover, since the spectral color coordinates of the first composite light LED light source 20d are located in the upper region of the Planck blackbody radiation curve in the CIE1931-xy chromaticity diagram, the above four non-white LED light sources 20L are used for mixing In the case of a small number of light sources, it can cover a large color gamut range, and the color coordinates can be adjusted within the color gamut range. At the same time, because the spectral energy distribution of the four non-white LED light sources covers The large and continuous visible light spectral wavelength range has high adjustment accuracy, and the spectral energy distribution can be changed continuously through light mixing. The light source module 10 is compatible with more functions (for example, it can be applied to a spectrum adjustment system, and under a set of fixed hardware conditions, light environments with different spectrums can be realized), and can meet various lighting requirements (for example, high-display lighting of lighting. chromaticity requirements, different rhythmic effect stimulation intensity requirements, and a combination of various lighting index requirements), thereby improving lighting performance and user experience (for example, while meeting the user's visual dimension requirements, providing users with rhythmic health. quality light environment).

Under the condition that there are only three kinds of LED light sources and the peak wavelengths of the three kinds of LED light sources are certain, the lighting spectrum and color coordinates that can be realized by this combination are in a one-to-one correspondence, that is, only a unique spectrum under the target color coordinates can be realized. However, in this embodiment, the LED light source 20L includes at least a first monochromatic LED light source 20a, a second monochromatic LED light source 20b, a third monochromatic LED light source 20c, and a first compound light LED light source 20d. The light-emitting unit 20 includes at least four channels, therefore, different lighting spectrum schemes can be realized under the same color coordinate, thereby realizing metamerism to meet different lighting requirements, for example, by changing the first monochromatic LED light source 20a , the light mixing ratio of the second monochromatic LED light source 20b, the third monochromatic LED light source 20c and the first compound light LED light source 20d, so as to obtain emission spectra with different spectral energy distributions, but still display the same color. Here, metamerism means that the color coordinates on the CIE1931-xy chromaticity diagram are the same but the spectral composition is different.

With reference to FIG. 2, FIG. 2 is a color coordinate point of the first single-color LED light source 20a, the second single-color LED light source 20b, the third single-color LED light source 20c and the first compound light LED light source 20d located on the CIE1931-xy chromaticity diagram schematic diagram. To be clear, in 1931 the CIE defined a number system for color that allows the calculation of color points, known as color coordinates, from the spectrum of color stimuli (i.e. light sources or light reflected from colored surfaces). The color coordinate defines the position of the color stimulus in the horseshoe diagram in Figure 2, where the x-coordinate and y-coordinate correspond to the values of the abscissa and ordinate in the chromaticity diagram, respectively, and all visible colors correspond to a color coordinate, and in Figure 2 The outer boundary of the horseshoe shape represents the colors and wavelengths of different wavelengths of monochromatic light.

Specifically, taking two LED light sources with adjustable luminous intensity as an example, on the chromaticity diagram, based on the color coordinates of any two light sources, the color point positions of the two light sources can be determined. Under the condition that the output light intensity (for example, illuminance) remains unchanged, by adjusting the proportion of the two in the total output light intensity (for example, illuminance), that is, the light mixing ratio, the composition of the two color points can be realized. Any color on the line, that is, the color of the light emitted after mixing can change along the line.

In this embodiment, the color point position of the first single-color LED light source 20a on the chromaticity diagram is point A, the color point position of the second single-color LED light source 20b on the chromaticity diagram is point B, and the third single-color LED light source 20b is located at point B on the chromaticity diagram. The color point position of the light source 20c on the chromaticity diagram is point C, the color point position of the first composite light LED light source 20d on the chromaticity diagram is point D, and the point A, point B, point D and point C are in sequence. connected to form a closed area, by adjusting the light mixing ratio (for example, the illuminance of the first single-color LED light source 20a, the second single-color LED light source 20b, the third single-color LED light source 20c, and the first composite light LED light source 20d) ratio), so that any color in the enclosed area can be realized, that is, the enclosed area is the first monochromatic LED light source 20a, the second monochromatic LED light source 20b, the third monochromatic LED light source 20c and the first composite light LED light source 20d can realize the color gamut range and color coordinate adjustable range, and, theoretically, each color coordinate in the enclosed area can realize infinitely different spectral schemes through the combination of the above light sources.

It can be seen from FIG. 2 that the spectral peak wavelengths of the first monochromatic LED light source 20a, the second monochromatic LED light source 20b and the third monochromatic LED light source 20c are located in the first spectral interval, the second spectral interval and the third spectral interval, respectively, The position of the first composite light LED light source 20d on the CIE1931-xy chromaticity diagram is located in the upper region of the Planck black body radiation curve L, and the spectrum of the first composite light LED light source 20d covers a large visible light spectral wavelength range, Therefore, the light source module 10 can cover a larger color by mixing light with the first single-color LED light source 20a, the second single-color LED light source 20b, the third single-color LED light source 20c and the first compound light LED light source 20d. gamut range, and the color coordinates can be adjusted within the color gamut range.

In this embodiment, among the first spectral peak wavelength, the second spectral peak wavelength and the third spectral peak wavelength, the second spectral peak wavelength is closer to the first spectral peak wavelength, thereby improving the ability of the light source module 10 to respond to short wavelengths of visible light. The adjustment accuracy of the spectrum of the wavelength band is easy to satisfy the indexes related to the short wavelength band, for example, the rhythmic effect stimulation intensity index and the color rendering related index. Among them, the indicators related to the short wavelength band of visible light have a strong correlation with healthy lighting, which can better meet the living needs of users.

In this embodiment, the spectrum of the first composite light LED light source 20d satisfies: the fourth spectral peak wavelength is between the first spectral peak wavelength, the second spectral peak wavelength and the third spectral peak wavelength with a larger interval between two adjacent spectral peak wavelengths, therefore, the first composite light LED light source 20d can also fill part of the spectral interval between two adjacent spectral peak wavelengths with a larger interval, thereby further improving the mode of the light source. The light mixing capability of the group 10 makes the spectral energy distribution of the light source module 10 more continuous after light mixing, so that it is easy to meet different requirements such as color rendering and spectral energy efficiency.

In this embodiment, the type of the first composite light LED light source 20d is a phosphor converted LED (phosphor converted LED, PCLED) light source. The light-emitting principle of the phosphor-converted LED light source is that the light of the first wavelength excites the phosphor to emit light of the second wavelength. Compared with the combination of multiple monochromatic LED light sources to form a corresponding composite light LED light source group, the PCLED light source only needs to use a monochromatic LED light source, and obtain a more continuous spectral energy distribution by combining the monochromatic LED light source with phosphors. Compound light LED light source, therefore, the cost of PC LED light source is lower, which is beneficial to reduce the manufacturing cost of the light source module 10, and because the spectral energy distribution of the PC LED light source is more continuous, it is correspondingly beneficial to improve lighting energy efficiency and color rendering performance. Functional indicators are also better.

In this embodiment, the first spectral peak wavelength is less than or equal to 465 nm, the third spectral peak wavelength is greater than or equal to 610 nm, and the second spectral peak wavelength is between the first spectral peak wavelength and the third spectral peak wavelength between wavelengths. Wherein, the first spectral peak wavelength is less than or equal to 465nm, so as to be close to the lowest boundary of the horseshoe-shaped color gamut in the CIE1931-xy chromaticity diagram, so as to cover the larger color gamut and chromatic coordinate adjustable range as much as possible, so The third spectral peak wavelength is greater than or equal to 610nm, so as to be close to the rightmost boundary of the horseshoe-shaped color gamut range in the CIE1931-xy chromaticity diagram, thereby possibly covering a larger color gamut range and color coordinate adjustable range.

Specifically, the first spectral peak wavelength is in the range of 440nm to 465nm, the second spectral peak wavelength is in the range of 480nm to 510nm, the third spectral peak wavelength is in the range of 610nm to 635nm, and the fourth spectral peak wavelength is in the range of 510nm to 510nm. 560nm range. That is to say, the emission color of the first single-color LED light source 20a is royal blue, the emission color of the second single-color LED light source 20b is indigo cyan, and the third single-color LED light source is cyan. The emission color of the light source 20c is redorange, and the emission color of the first composite light LED light source 20d is mint green.

It should be noted that the first composite light LED light source 20d with the fourth spectral peak wavelength is close to the peak wavelength (555nm) of the photopic spectral luminous efficiency function V(λ) because the spectral peak wavelength is relatively continuous and the spectral energy distribution is relatively continuous. The spectral response curve corresponding to the photopic spectral luminous efficiency function V(λ) has a high degree of coincidence, so that the overall spectrum of the first composite light LED light source 20d has a high energy efficiency, so that when the first composite light LED light source 20d is used When the light source 20d performs light mixing, it is beneficial to improve the lighting energy efficiency.

In this embodiment, the type of the first composite light LED light source 20d is a phosphor-converted LED light source. As an example, the first composite light LED light source 20d excites the phosphor to emit mint green light through light with a shorter wavelength in the visible light band (eg, blue light or blue-violet light).

First, with reference to FIG. 4, FIG. 4 is a response curve of melanin spectrum optical efficiency, the abscissa represents the wavelength (nanometer), and the ordinate represents the relative intensity. It can be seen from FIG. retinal ganglion cells, ipRGCs) are most sensitive to light with wavelengths around 480nm to 490nm, that is, light stimulation with a peak wavelength around 480nm to 490nm can effectively provide higher rhythmic stimulation, therefore, by using the second spectral peak wavelength The second monochromatic LED light source 20b in the range of 480nm to 510nm enables the light source module 10 to precisely adjust the spectral intensity of the corresponding wavelength band, thereby satisfying different stimulation requirements of the photoreceptor cells.

Secondly, the first spectral peak wavelength corresponding to the first monochromatic LED light source 20a is in the range of 440nm to 465nm, so the first monochromatic LED light source 20a and the second monochromatic LED light source 20b can be used to mix light to obtain a peak wavelength at The mixed light between the first spectral peak wavelength and the second spectral peak wavelength, that is, using the first monochromatic LED light source 20a and the second monochromatic LED light source 20b, can cover the spectral range of 440nm to 510nm; at the same time, By making the first spectral peak wavelength in the range of 440nm to 465nm, the rhythmic stimulation can also be adjusted to a certain extent by changing the light mixing ratio of the first monochromatic LED light source 20a and the second monochromatic LED light source 20b. For this reason, the first monochromatic LED light source 20a and the second monochromatic LED light source 20b in the above-mentioned peak wavelength range are beneficial to ensure the function of the light source module 10 corresponding to the spectral range of 440nm to 510nm, so as to satisfy the user's requirements. General application requirements. Moreover, the first monochromatic LED light source 20a also has a certain luminous intensity below 440 nm, and can also achieve a function corresponding to a spectral range with a wavelength below 440 nm to a certain extent.

Meanwhile, based on the fact that the first spectral peak wavelength is in the range of 440nm to 465nm and the second spectral peak wavelength is in the range of 480nm to 510nm, the interval between the peak wavelengths of the second monochromatic LED light source 20b and the first monochromatic LED light source 20a is relatively small. Therefore, the adjustment accuracy of the spectrum in the short wavelength band of visible light is improved, and the index related to the short wavelength band of visible light is easily satisfied. For example, the stimulation of different types of photoreceptor cells can be controlled more finely. Specifically, through the light mixing of the first monochromatic LED light source 20a and the second monochromatic LED light source 20b, the photoreceptor cells (S cone cells, S cone cells), rhythm and rhythm sensitive to the short wavelength spectrum of visible light can be satisfied. Different stimulation of effector-related non-visual photoreceptor cells (ipRGCs) and scotopic-related photoreceptor cells (rod cells, Rod cells) facilitates precise control of the stimulation intensity of different photoreceptor cells. Among them, different photoreceptor cells have different photosensitivity characteristics. The adjustment of the first monochromatic LED light source 20a can provide more precise stimulation intensity control for the S-shaped cone cells, and the adjustment of the second monochromatic LED light source 20b can provide a more precise control of the stimulation intensity. ipRGCs provide more precise stimulus intensity control.

Moreover, the fourth spectral peak wavelength corresponding to the first composite light LED light source 20d is in the range of 510 nm to 560 nm. On the basis of the second monochromatic LED light source 20b, the first composite light LED light source 20d realizes the continuation of the wavelength, Thus, the spectral adjustment range of the light source module 10 is further expanded. At the same time, referring to FIG. 3 , FIG. 3 is a relative spectral range diagram of each LED light source 20L in an embodiment of the light source module 10 , a curve 21 is a spectral wavelength range diagram of the first monochromatic LED light source 20a , and a curve 22 is the first The spectral wavelength range diagram of the two monochromatic LED light sources 20b, the curve 23 is the spectral wavelength range diagram of the third monochromatic LED light source 20c, and the curve 24 is the spectral wavelength range diagram of the first composite light LED light source 20d. The spectrum of the first composite light LED light source 20d with a peak wavelength of 510nm to 560nm covers a large spectral wavelength range, so that the spectral energy distribution of the light source module 10 is relatively continuous to meet different color rendering requirements. In addition, the peak wavelength and spectral energy distribution of the first composite light LED light source 20d have a high degree of coincidence with the peak wavelength and spectral response curve of the photopic spectral luminous efficiency function V(λ), which is beneficial to improve the first composite light The energy efficiency of the overall spectrum of the LED light source 20d. As an example, the color coordinate of the first composite light LED light source 20d is (0.3873, 0.4829).

Again, the third spectral peak wavelength corresponding to the third monochromatic LED light source 20c is in the range of 610nm to 635nm, therefore, the third monochromatic LED light source 20c, the first monochromatic LED light source 20a, the second monochromatic LED light source can be used 20b, the first composite light LED light source 20d performs light mixing, so that the spectrum obtained after the light mixing can obtain higher color rendering.

The proportion of output light intensity (eg, illuminance) is used for light output, which can realize different lighting spectrum schemes.

Since the combination of the four kinds of LED light sources can cover a large color gamut range and a color coordinate adjustable range, the first composite light LED light source 20d can be used as the basis for light mixing, so that the matching can meet the requirements of short wavelength band, medium The monochromatic LED light source in the wavelength band and the long wavelength band is easy to obtain a larger and more continuous spectrum adjustment range, so that a variety of adjustable spectrums can be realized, that is, light environments that can have different spectrums.

In this embodiment, the fifth spectral peak wavelength is at In the range of 460 nm to 485 nm, the sixth spectral peak wavelength is in the range of 560 nm to 610 nm. That is, the emission color of the fourth single-color LED light source 20e is blue, and the emission color of the second composite light LED light source 20f is amber.

The fourth monochromatic LED light source 20e is used to fill the spectral range between the first monochromatic LED light source 20a and the second monochromatic LED light source 20b, thereby improving the adjustment accuracy of the light source module 10 during light mixing, and The adjustable range of the color gamut of the light source module 10 further enhances the functionality of the light source module 10 . Moreover, the wavelength of the fifth spectral peak corresponding to the fourth monochromatic LED light source 20 is in the range of 460nm to 485nm, and this wavelength range is related to rhythmic stimulation to a certain extent, thereby further improving the adjustment accuracy of rhythmic stimulation.

The second compound light LED light source 20f is used to fill the spectral range between the first compound light LED light source 20d and the third monochromatic LED light source 20c, thereby further increasing the color gamut of the light source module 10 during light mixing and the adjustable range of color coordinates, thereby further enhancing the functionality of the light source module 10 .

In this embodiment, the type of the second composite light LED light source 20f is a phosphor-converted LED light source. As an example, the second composite light LED light source 20f excites the phosphor to emit amber light by using light with a shorter wavelength in the visible light band (eg, blue light or blue-violet light). For the analysis of the reasons for using phosphors to convert the LED light source, reference may be made to the foregoing description of the first composite light LED light source 20d, which will not be repeated here.

The white light source 20g has a wider spectral range, thereby further increasing the continuity of the spectral energy distribution of the light source module 10 during light mixing. In this embodiment, the relative color temperature (Correlated ColorTemperature, CCT) of the white LED light source 20g is 1800K to 13000K. As shown in FIG. 3, the curve 29 is a graph of the spectral wavelength range of the white LED light source 20g. Specifically, FIG. 3 shows a spectral wavelength range diagram of a white LED light source 20g with a relative color temperature of 4000K.

It should be noted that, since the multi-channel light-emitting unit 20 includes a variety of different types of LED light sources 20L, which can cover a wide range of visible light wavelengths, it is easy to obtain high color rendering, and under different color temperatures, all can be obtained Higher color rendering index. Correspondingly, since different types of LED light sources 20L are selected, it is beneficial to improve the limitation on the relative color temperature of the white LED light sources 20g, so that the white LED light sources 20g with different relative color temperatures can be compatible.

In this embodiment, according to the spectral peak wavelength, the LED light source 20L further includes one of a fifth monochromatic light source 20h having a seventh spectral peak wavelength and a sixth monochromatic light source 20i having an eighth spectral peak wavelength one or more.

Continuing to refer to FIG. 3 , the curve 27 is the spectral wavelength range diagram of the fifth monochromatic light source 20h, and the curve 28 is the spectral wavelength range diagram of the sixth monochromatic light source 20i. In this embodiment, the seventh spectral peak wavelength is between 420 nm and 420 nm. In the range of 440m, the eighth spectral peak wavelength is in the range of 635nm to 680m. That is, the emission color of the fifth monochromatic light source 20h is violet, and the emission color of the sixth monochromatic light source 20i is red.

The fifth monochromatic light source 20h is used to fill in the spectral range with the wavelength less than 440 nm, thereby further improving the adjustment accuracy of the spectrum of the visible light short wavelength band, so as to satisfy the short wavelength band related index. For example, the stimulation of different types of photoreceptor cells can be controlled more finely.

The sixth monochromatic light source 20i is used to fill the spectral range with a peak wavelength greater than 635 nm, thereby further increasing the spectral wavelength range and color gamut range of the light source module 10 during light mixing, thereby further enhancing the light source Functionality of the module 10 .

In this embodiment, according to the spectral peak wavelength, the LED light source 20L further includes a third composite light LED light source 20j having at least a ninth spectral peak wavelength, and the ninth spectral peak wavelength is in the range of 510nm to 560nm. That is, the emission color of the third composite light LED light source 20j is mint green.

The third composite light LED light source 20j and the first composite light LED light source 20d have the same peak wavelength range, and the spectral range is wider, so that the LEDs with peak wavelengths in the range of 510nm to 560nm can be increased according to actual needs. The adjustment precision of the luminous intensity of the light source 20L, and the adjustable range of the luminous intensity.

Specifically, according to actual requirements, the values of the ninth spectral peak wavelength and the fourth spectral peak wavelength may be the same or different. Wherein, when the values of the ninth spectral peak wavelength and the fourth spectral peak wavelength are different, that is, within the range of 510nm to 560nm, two different composite light LED light sources with specific peak wavelength spectra are selected, thereby further The color gamut range, color coordinate adjustable range and adjustment precision of the light source module 10 during light mixing are increased, thereby further enhancing the functionality of the light source module 10 . When the ninth spectral peak wavelength and the fourth spectral peak wavelength have the same value, the absolute intensity of a specific peak wavelength spectrum can be enhanced, thereby further enhancing the functionality of the light source module 10 and the adjustment range of the light intensity.

In this embodiment, the type of the third composite light LED light source 20j is a phosphor-converted LED light source. As an example, the third compound light LED light source 20j excites the phosphor to emit mint green light by using light with a shorter wavelength in the visible light band (eg, blue light or blue-violet light). For the analysis of the reasons for using phosphors to convert the LED light source, reference may be made to the foregoing description of the first composite light LED light source 20d, which will not be repeated here.

Based on the foregoing analysis, in the case that the light source module 10 has a small number of light sources, even if the number of the LED light sources 20L corresponding to the same spectral peak wavelength is one, it can already cover a large color gamut range and a color coordinate adjustable range , a variety of adjustable spectrums can be obtained, which can meet various lighting requirements, thereby significantly reducing the cost of the light source module 10 while ensuring that the light source module 10 has strong functionality.

According to actual requirements, the number of LED light sources 20L corresponding to the same spectral peak wavelength can be reasonably set, and the number of LED light sources 20L corresponding to the same spectral peak wavelength is one or more.

For example, the third composite light LED light source 20j and the first composite light LED light source 20d have the same peak wavelength range and spectral energy distribution, therefore, the number of the third composite light LED light source 20j and the first composite light LED light source 20d In the case of one, when the values of the ninth spectral peak wavelength and the fourth spectral peak wavelength are the same, it can be considered that the number of LED light sources 20L corresponding to the spectral peak wavelength is two, and at this time, the number of LED light sources 20L can be regarded as two. The adjustment precision of the corresponding spectrum is further improved to achieve functional enhancement. Similarly, when the number of the third composite light LED light source 20j and the number of the first composite light LED light source 20d is one, when the values of the ninth spectral peak wavelength and the fourth spectral peak wavelength are different, It can be considered that the number of LED light sources 20L corresponding to the fourth spectral peak wavelength is one, and the number of LED light sources 20L corresponding to the ninth spectral peak wavelength is one. At this time, the light source module 10 can be realized under the premise of saving costs. functional expansion.

It should be noted that when there are at least a first monochromatic LED light source 20a, a second monochromatic LED light source 20b, a third monochromatic LED light source 20c and a first composite light LED light source 20d, and the LED light sources with the same spectral peak wavelength are located in the same In the case of the light-emitting channel, according to actual needs, one or more light sources can be selected from the remaining LED light sources 20L, so that five-channel, six-channel, seven-channel, eight-channel, nine-channel and ten-channel and above can be obtained respectively. The light source module 10 .

It can be understood that, when the LED light sources 20L of the same spectral peak wavelength are located in different light emitting channels, correspondingly more channels of light source modules 10 can be obtained. For example, in the case of having only the first single-color LED light source 20a, the second single-color LED light source 20b, the third single-color LED light source 20c and the first compound light LED light source 20d, the number of the first single-color LED light source 20a is One, the number of the second single-color LED light sources 20b is three, and located in the same light-emitting channel, the number of the third single-color LED light sources 20c is one, and the number of the first composite light LED light sources 20d is two, and located in different In this case, a five-channel light source module 10 can also be obtained.

It should also be noted that, in the light source module 10, according to actual requirements, the LED light sources 20L with the same spectral peak wavelength are located in the same light emitting channel, or the LED light sources 20L with the same spectral peak wavelength are located in different light emitting channels. Wherein, when the number of LED light sources 20L with the same spectral peak wavelength is multiple, when the LED light sources 20L with the same spectral peak wavelength are located in different light-emitting channels, the LED light sources 20L corresponding to the same spectral peak wavelength can be individually controlled. , thereby further increasing the color gamut range, color coordinate adjustable range and adjustment precision of the light source module 10 during light mixing, thereby further enhancing the functionality of the light source module 10 . For example, taking two LED light sources 20L corresponding to the same spectral peak wavelength as an example, by independently controlling the two LED light sources 20L, their luminous intensity (eg, output light intensity) can be adjusted respectively, and different lighting spectrum schemes can be obtained to meet the Actual demand.

In addition, in each of the multi-channel light-emitting units 20, the arrangement of the LED light sources 20L can be designed according to actual needs, for example, according to the number of LED light sources 20L and the type of lamps used by the light source module 10 or lighting needs. Specifically, the arrangement of the LED light sources 20L includes: a rectangular array arrangement, a ring arrangement, a strip arrangement, a zigzag arrangement or a regular polygon arrangement. Wherein, the annular arrangement includes a single annular arrangement or a multiple annular arrangement (eg, a double annular arrangement).

In this embodiment, in the multi-channel light-emitting unit 20, the arrangement of the LED light sources 20L satisfies that the LED light sources 20L in the multi-channel light-emitting unit 20 are uniformly distributed and can mix light evenly (for example, the LED light sources 20L in the multi-channel light-emitting unit 20 The LED light sources 20L are arranged in an annular shape). As shown in FIG. 1 , taking the multi-channel light-emitting unit 20 including the aforementioned ten LED light sources 20L as an example, the LED light sources 20L are arranged in a 2*5 rectangular array.

It should be noted that, in each of the multi-channel light-emitting units 20, the LED light source 20L includes a monochromatic LED light source and a composite light LED light source, and a monochromatic LED light source whose spectral peak wavelength is smaller than the second spectral peak wavelength. It is arranged staggered from the compound light LED light source. The wavelength of the light emitted by the monochromatic LED light source whose spectral peak wavelength is less than the second spectral peak wavelength is shorter, and the short-wavelength band spectral range mainly emits blue light. According to the foregoing description, the compound light LED light source usually passes through the visible light band with shorter wavelengths. The light (for example, blue light or blue-violet light) excites the phosphor to emit light of the corresponding color. Therefore, by staggering the monochromatic LED light source with the spectral peak wavelength smaller than the second spectral peak wavelength and the composite light LED light source to reduce The influence of a single-color LED light source with a small spectral peak wavelength and a small wavelength on the composite light LED light source is beneficial for the light source module 10 to emit mixed light that meets the lighting requirements. For example, if a specific monochromatic LED light source with a smaller spectral peak wavelength is placed adjacent to a specific composite light LED, then when the specific monochromatic LED light source needs to be turned on, but the specific composite light LED light source does not need to be turned on, the specific monochromatic LED light source does not need to be turned on. The light emitted by the light source easily excites the phosphor of the specific composite light LED light source, thereby causing the specific composite light LED light source to be turned on by mistake, thereby affecting the final light mixing effect.

In addition, FIG. 6 shows the case where the shape of the circuit board 60 is a circle. However, the shape of the circuit board 60 is not limited to a circle.

As shown in FIG. 7 , FIG. 7 is a schematic structural diagram of still another embodiment of the light source module of the present invention. In yet another embodiment, the arrangement of the LED light sources 70 is a bar-shaped arrangement, that is, a "one"-shaped arrangement.

Since the light source module 130 of this embodiment can cover a large color gamut range and a color coordinate adjustable range, it is easy to obtain various tunable spectrums through light mixing, that is, light environments with different spectrums can be realized. At the same time, because the light source module The group 130 has a variety of monochromatic light sources and composite light sources with different peak wavelengths, which can cover a continuous spectral wavelength range and have a high degree of freedom in adjustment. The adjustment of spectral indexes such as chromaticity index in a wide range, correspondingly makes the light source module 130 compatible with more functions (for example, it can be applied to a spectral adjustment system, and under a set of fixed hardware conditions, it can achieve different spectral light environment), can meet various lighting requirements (for example, the color rendering requirements of light or rhythm effect indicators), thereby enhancing the functionality and user experience of the luminaire 100 (for example, in meeting the user's visual dimension requirements) At the same time, it provides users with a high-quality light environment that is in line with rhythm and health).

As an example, when the lamp 100 is a downlight, the downlight has a variable light projection angle to achieve different light projection directions, thereby obtaining different spatial light distributions, and further obtaining a light environment with adjustable light distribution. It can be understood that, in other embodiments, the lamps may also be of other types, for example, the lamps may also be other types of strip lights, projection lamps, rectangular lamps, and the like. The number of the light source modules 130 is determined according to the type or application scenario of the lamp 100 . For example, taking the lamp 100 as a wall washer as an example, the number of the light source modules 130 may be 1 to 10.

The control module 120 is used to individually control the luminous intensity of the LED light source corresponding to each channel in the multi-channel light emitting unit, thereby improving the control accuracy of the light mixing effect, and then accurately controlling the output light intensity of the lamp 100 to output the corresponding output light intensity. . As an example, the output light intensity is illuminance, specifically the illuminance at the selected measurement reference reference plane or reference point.

The light source module 130 only includes the first monochromatic LED light source, the second monochromatic LED light source, the third monochromatic LED light source and the first composite light LED light source, and the LED light sources with the same spectral peak wavelength are located in the same light emitting channel as an example At this time, the light source module 130 has four channels, and the control module 120 is used to individually control the luminous intensity of the first monochromatic LED light source, the second monochromatic LED light source, the third monochromatic LED light source and the first composite light LED light source.

That is, for any channel, when the number of LED light sources corresponding to the channel is multiple, the control module 120 simultaneously controls all the LED light sources of the channel. For example, the number of light source modules 130 is one, the number of first single-color LED light sources in the multi-channel light-emitting unit is multiple, and each first single-color LED light source is located in the same light-emitting channel, or the light source module 130 The number of LEDs is multiple, and each of the first single-color LED light sources is located in the same light-emitting channel, the dimming module 120 is used to control the multiple first single-color LED light sources at the same time.

Through the power supply module, the input current of the first voltage value is converted into a low-voltage current of the second voltage value acceptable to the decoder, so as to facilitate the normal use of the decoder. As an example, the first voltage value is 220V, and the second voltage value is 12V to 48V.
