detailed description

A light source module and lighting device proposed by the present invention will be further described in detail below with reference to the accompanying drawings and some preferred embodiments in accordance with the present invention.

The light source module provided by the present invention is an emitting light source, which can be applied to the lighting device 101 shown in FIG. 1 for daily lighting. The lighting device 101 includes a power supply module (not shown) and a controller 102 , a heat sink 103 , a lighting module 104 , a lampshade 105 , etc., which provide power required for the light source module to work. The controller 102 can be used to adjust the illumination light emitted by the light source module 104, such as light color, light intensity, etc., and the lampshade 105 can be replaced with other optical elements according to the design of the lighting device 101 in other embodiments, such as lenses, diffusion elements, light guides, etc. etc., which may not include the radiator.

A specific embodiment of the light source module 104 of the present invention is a light-mixing white LED package chip. As shown in FIG. 2 , the light source module 104 includes at least a first light-emitting element 1041 and an additional light-emitting body. In this embodiment, the first light-emitting element 1041 is a blue LED chip, which is directly excited by semiconductor materials to emit light. The peak wavelength of the light is at 430-470nm, and the light color is blue. Here we call the light emitted by the first light-emitting element 1041 is the first color light. In another preferred embodiment, a blue LED chip with a peak wavelength position of 435-465 nm may also be used. LED chip (LED Chip), including front-mounted or flip-chip, a single LED Chip or multiple LED Chips are connected together in series, parallel or series-parallel. In other implementations, the first light-emitting element 1041 can also adopt the mode of LED chips and phosphor powder, that is, it includes semiconductor light-emitting elements (LED chips) and absorbs the light emitted by semiconductor light-emitting elements (LED chips) and emits blue light through wavelength conversion. The blue-light phosphor powder, the semiconductor light-emitting element here can be a monochromatic LED chip that emits ultraviolet light. The role of the additional illuminant in the light source module 104 is to receive part of the light emitted by the first light-emitting element and convert it into light of a second color different from the first color. In this embodiment, the additional illuminant at least It contains two phosphors with different light colors, and the light emitted by the additional luminous body has a peak wavelength greater than or equal to 620nm, and a more preferable peak wavelength is in the region of 630-660nm. The light emitted by the light source module 104 is formed after the light of the first color and the light of the second color are mixed, and the emitted light of the light source module 104 is white light.

Since the first light-emitting element 1041 blue LED chip is used as the excitation light source in the light source module 104, although a large part of the light emitted by the blue LED chip has undergone wavelength conversion through an additional luminous body, there is still a part of energy that has not been converted. , these energies form the first peak in the wavelength range of 430~470nm, the main source of energy of this peak is the first light-emitting element 1041, and the light converted by the additional luminous body will also have part of the energy in this wavelength range, the two After mixing, the first peak may not completely coincide with the peak wavelength position of the original first light-emitting element 1041 blue LED chip, and there may be a slight shift. The light emitted by the light source module 104 has a second peak in the wavelength range of 630-660 nm, and the energy of this peak is mainly provided by the additional luminous body. In order to produce candlelight color, the ratio of the spectral intensity of the first peak to the spectral intensity of the second peak must be less than or equal to 20%.

Taking the blackbody radiation spectrum with the same color temperature and the same Y (luminous flux) as the light emitted by the light source module as the reference spectrum, the blackbody radiation formula is as follows:

in, ,

λ radiation wavelength (μm); c speed of light (2.998×10^8m/s ); h Planck constant 6.626×10^-34 J·S; K Boltzmann constant (Boltzmann) 1.3806505*10^-23J/ K; CCT correlated color temperature.

The emission spectrum of the light source module 104 has the following characteristics. In the region between 380nm and the peak wavelength of the second peak, the difference A between the spectral intensity of the light emitted by the light source module and the spectral intensity of the reference wavelength at the same wavelength (λ) satisfies the following condition -2.0≤A(λ)≤2.0, and in some better embodiments -1.0≤A(λ)≤1.0. The calculation formula of A(λ) is as follows:

;

Wherein: P(λ) is the luminescence spectrum of the light source module, R(λ) is a reference spectrum having the same color temperature and the same luminous flux as the light source module, and V(λ) is the photopic spectrum luminous efficiency function.

Another feature of the light spectrum emitted by the light source module is that the spectrum is continuously distributed in the visible light range of 380~780nm, that is, the difference between the spectral intensities of any two adjacent wavelengths (the interval width is 5nm) in the 380~780nm region The ratio of the absolute value of and the spectral intensity of the second peak is less than or equal to 8.0%. Certainly the continuity of the smaller spectrum of this ratio value is better, in another preferred embodiment, can realize the absolute value of the difference of the spectral intensity of any two adjacent wavelengths (the interval width is 5nm) and the second peak The ratios of spectral intensities are all less than or equal to 6.5%

The light color of the light emitted by the light source module 104 with the above spectral characteristics is in the CIE1931 color space, located in the interval surrounded by points with a correlated color temperature of 1850~2150K and a distance between -0.005~0.005 from the black body locus, that is, duv∈[ -0.005,0.005], area 1 shown in Figure 3. More preferably, it is located within the ellipse range of the center point x0=0.5267, y0=0.4133, long axis a=0.00233, short axis b=0.00132, inclination θ=47.9°, SDCM=5.0, as shown in Figure 3 2. The color rendering parameter CRI of this spectrum is not less than 90, R9 is not less than 50, and the color gamut index Rg is not less than 90.

In order to realize the above-mentioned light color and spectrum, the additional illuminant in this embodiment is a package 1042 mixed with phosphor powder. The material of the package 1042 can be resin or silica gel, and the transparent resin can be epoxy resin or urea resin. The encapsulation body 1042 and phosphor powder are evenly mixed and coated on the first light emitting element 1041 , as shown in FIG. 15 . In this embodiment, we use fluorescent powder to achieve wavelength conversion, but in order to achieve the spectral continuity required by the present invention, if only one kind of fluorescent powder is used, its half width is limited, and it is impossible to realize wavelength conversion in such a large range of 380~780nm. The distribution is continuous, so the additional illuminants include at least two phosphors with different light colors. In this embodiment, the additional luminous body includes the first phosphor 1043, which is a red or orange phosphor with a peak wavelength of emitted light at 600-670 nm and a spectral half-width of emitted light of 80-120 nm, preferably 80-100 nm. ; The second phosphor 1044 is a green phosphor with a peak wavelength of emitted light at 520-560nm and a half-width of the emission spectrum of 60-115nm, preferably 90-115nm.

Through the joint action of the red phosphor and the green phosphor, the emission spectrum of the light source module 104 in this embodiment can basically achieve a continuous distribution within the range of 380-780 nm. In order to make the spectrum curve smoother, other types of phosphors can be added on the basis of red phosphors and green phosphors.
