All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The lighting device in the prior art is difficult to improve the skin complexion of people. The present invention provides a light source module and a lighting device for solving the above problems, which will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the lighting device 101 includes a controller 102, a heat sink 103, a light source module 104, and an optical element 105.
Of course, the heat sink 103 and the optical element 105 are not necessary features of the lighting device 101, and in some lighting scenes, these two elements may be omitted and are not described herein.
The lighting device 101 may be various types of lamps, such as a ceiling lamp, a decorative lamp, or even a spot lamp, and the application environment may be a home environment, a business environment, or the like.
The controller 102 is configured to adjust the light color and the light intensity of the illumination light emitted by the light source module 104, the heat sink 102 is configured to dissipate heat generated during the illumination of the light source module 104, and the optical element 105 includes various types such as a lens and a lampshade, and is configured to adjust the illumination direction and the angle of the illumination light emitted by the light source module 104.
The structure and operation of the controller 102, heat sink 103, and optical element 105 are well known to those skilled in the art and are not expanded herein.
The light source module 102 includes a blue light generating part, a red light generating part, and a yellow-green light generating part, which are respectively configured to emit blue light, red light, and yellow-green light.
The blue light generating section may employ a light emitting unit configured to emit blue light, or may employ a light emitting unit emitting light of another color in cooperation with one blue phosphor to emit desired blue light.
The red light generating section may employ a light emitting unit configured to emit red light, or may employ a light emitting unit emitting light of other colors in cooperation with one red phosphor to emit desired red light.
The yellow-green light generating section may employ a light emitting unit configured to emit yellow-green light, or may employ a light emitting unit emitting light of another color in cooperation with one yellow-green phosphor to emit desired yellow-green light.
In the embodiment of the present invention, the blue light generating portion, the red light generating portion and the yellow-green light generating portion may each have a separate light emitting unit, or may share one light emitting unit, for example, only the blue light generating portion may include a light emitting unit, while the red light generating portion and the yellow-green light generating portion may have only phosphors, and the phosphors of the red light generating portion and the yellow-green light generating portion respectively adjust the blue light emitted by the blue light generating portion to corresponding red light and yellow-green light through wavelength conversion.
Of course, only the red light generating part may include the light emitting unit, and the blue light generating part and the yellow-green light generating part only have the phosphor, and the phosphor of the blue light generating part and the yellow-green light generating part respectively adjust the red light emitted by the red light generating part to the corresponding blue light and yellow-green light through wavelength conversion.
The light emitting unit can be selected as an LED element, or can be of other element types, which is not described herein.
The phosphor may be selected from aluminate phosphor, silicate phosphor, nitride phosphor, sulfide phosphor, and the like.
It is worth noting that: the yellow-green light generating part can comprise one phosphor for excitation to generate yellow-green light, or can adopt a combination of more than two phosphors, such as a phosphor capable of exciting yellow light and a phosphor capable of exciting green light, or even can be formed by combining phosphors with various peak wavelengths, when the phosphors are combined, the phosphors are not limited in one component, such as different yellow-green phosphors in two white light LED elements, and the spectra generated by the phosphors are superposed to obtain the required spectral intensity between 515 and 560 nm. The combination of such phosphors is not limited to the yellow-green light generating section, and when the blue light generating section and the red light generating section contain phosphors, phosphors of plural components may be used, and these phosphors may be distributed in different devices. The broad band phosphor is a general concept in the art, and refers to a phosphor having a wide excitation light full width at half maximum (FWHM) relative to a narrow band phosphor such as yttrium europium oxide (red powder) or a quantum dot phosphor, and the broad band phosphor in the present invention preferably has a full width at half maximum of more than 30nm, more preferably more than 40nm, particularly preferably more than 50nm, and particularly preferably more than 80 nm. In addition, the red light phosphor can also adopt a broadband phosphor, the red light wavelength band and the green light wavelength band are adjacent, the red light generating part also adopts the broadband phosphor and then has certain energy in the green light wavelength band, and thus, the light intensity of the wavelength band can be increased to a certain extent after the light is superposed with the light emitted by the yellow-green light generating part, so that the spectrum required by the invention is met. It should be noted that the red light generating part and the yellow-green light generating part are only one description adopted for illustrating the present invention, and as the emission bandwidth of the red phosphor is wider, part of the energy is necessarily in the yellow-green light region, at this time, we can understand that the red phosphor part realizes the function of the red light generating part and part contributes to the yellow-green light emission, that is, the yellow-green light generating part is composed of the yellow-green phosphor and the red phosphor.
The composition of the illumination light emitted by the illumination device 101 is described below in conjunction with the structure of the illumination device 101.
Fig. 2 is a graph comparing the spectra of the illumination light emitted from the illumination device 101 and the illumination light in the prior art. L1 is a spectral distribution diagram of the lighting device 101 of the present invention at a color temperature of 3000K, and a dotted line L2 is a spectral distribution diagram of the conventional lighting device at 3000K, and its main peak is blue light with a wavelength of 450 nm. Here we set the main peak energy to 1, and the energies of other points are shown in the graph as relative to the main peak energy, and the red light peak is closer to the long wave than L2, the peak intensity is also higher, and the spectrum intensity at 560-590 nm is lower than that of L2, which is proved by a lot of experiments: under the L1 light environment, the skin whiteness, redness and health degree are obviously superior to those under the L2 light environment.
The color temperature of 3000K is basically close to the color temperature range of the current home location, and the illumination light emitted by the illumination device 101 provided by the invention greatly improves the skin impression of people at the home location.
In the embodiment of the invention, the peak wavelength of the blue light is in the range of 440-460 nm.
The peak wavelength of the red light is within the range of 600-640nm, and the peak intensity of the blue light is 65-100% of the peak intensity of the red light. The red light is added on the basis of the blue light, so that the skin can be more ruddy in appearance, the aesthetic requirements of Chinese people are met, and the health degree of the skin is greatly improved. By setting the peak wavelength of the red light and its peak intensity, the skin is made to appear too red, which causes a visual difference.
In an embodiment of the present invention, the peak intensity of blue light at the lower end of the range of peak intensity of red light may also be 70%, or even further 80%; the peak intensity of blue light may also be 95% at the upper end of the range of peak intensities of red light. By combining the upper and lower values within this range, ranges of, for example, 70% to 95% or 80% to 95% are obtained, and red light within these ranges can achieve the object of the present invention.
The peak wavelength of the yellow-green light is within the range of 525-565 nm, and the peak intensity of the yellow-green light is 35% -65% of the peak intensity of the red light. The yellow-green light is added on the basis of the blue light and the red light, and the capability of the yellow-green light for blending the light color is utilized, so that the skin appearance is more real, and the authenticity of the skin appearance is ensured.
In the embodiment of the present invention, the lower limit value of the range of the peak intensity of yellow-green light in the peak intensity of red light may also be 40%; the peak intensity of red light may also be 60% at the upper limit of the range of peak intensities of red light. By combining the upper and lower limits within this range, a range of, for example, 40% to 60% is obtained, and yellow-green light within these ranges can achieve the object of the present invention.
When the light source module has no other light, the irradiating light emitted by the light source module meets the following conditions in a CIE1931 color coordinate system: the abscissa X is within the range of 0.4015-0.4315; the ordinate Y is within the range of 0.347-0.377.
The color coordinate reflects the position of the measured object in the chromaticity diagram, and is a basic parameter for expressing color by a mathematical method, and the abscissa X and the ordinate Y of the measured object can be obtained by the following method: after obtaining the spectrum P (lambda), multiplying the spectrum P (lambda) with the tristimulus functions x (lambda), y (lambda) and z (lambda) corresponding to the wavelengths respectively, and accumulating to obtain tristimulus values x, y and z. And then converting the tristimulus values X, Y and z to obtain the X-X/(X + Y + z) and the Y-Y/(X + Y + z) coordinates of the color coordinates. Are well known to those of ordinary skill in the art and are not expanded herein.
It should be noted that when the irradiation light of the light source module is determined to meet the above conditions in the CIE1931 color coordinate system, the environment where the light source module is located does not have any light, so that the phenomenon that the position of the irradiation light emitted by the light source module in the chromaticity diagram cannot be accurately determined due to the irradiation light pollution emitted by the light source module caused by the existence of other light doped in the irradiation light emitted by the light source module is avoided.
In the embodiment of the invention, the light source module can be arranged in a darkroom or a black box isolated from the external light, so that no other light exists in the environment where the light source module is positioned, and the irradiation light emitted by the light source module is determined to accord with the conditions in the CIE1931 color coordinate system.
In an embodiment of the invention, the conditions in the color coordinate system may be adjusted to: the abscissa X is in the range of 0.4065-0.4265; the ordinate Y is within the range of 0.352-0.372.
In an embodiment of the present invention, the conditions in the color coordinate system may also be adjusted to: the abscissa X is in the range of 0.4115-0.4225; the ordinate Y is within the range of 0.357-0.367.
The lighting device provided by the invention is mainly applied to lighting and can improve the appearance of skin in an illumination environment.
