In this embodiment, the color temperature light source 10 and the adjusting light source set 20 both use LED light sources. The first color temperature points P1 include at least color temperature points of 2700K, 3000K, 4000K, 5000K, 5700K, 6500K.
Referring to fig. 3, the color temperature light source 10 is a light source having a solar-like spectrum whose spectral distribution is close to the visible portion of the real solar spectrum. Before the light source set 20 is adjusted to emit light, the first color temperature point P1 of the color temperature light source 10 is the first color temperature point P1 of the lighting module 100. The color temperature light source 10 and the adjusting light source group 20 adjust the brightness by adjusting the input current. Namely, the color temperature light source 10 and the adjusting light source group 20 adjust the brightness by adjusting the current duty ratio.
Therefore, the lighting module 100 of the present application forms the second color temperature point P2 and the third color temperature point P3 which are located at two sides of the first color temperature point P1 and located on the planck black body radiation curve L, and further the first color temperature point P1, the second color temperature point P2 and the third color temperature point P3 can make the color temperature points of the lighting module 100 on the planck black body radiation curve continuous, and further the newly generated color temperature points of the lighting module 100 can generate new spectrums, which can make up the partial spectrums of the lighting module 100 missing due to the process problem, and solve the technical problem that the lighting module has an influence on the physiological rhythm of the human body due to the missing of the color temperature points and the missing of the partial spectrums.
When the color temperature points of the lighting module 100 on the planck black body radiation curve are continuous, the lighting module 100 can simulate the light spectrum close to the real solar spectrum, and then the light spectrum of the lighting module 100 can be adjusted by changing the color temperature to be close to the solar spectrum in the real environment, such as simulating the solar spectrum close to the morning, the noon and the evening and the solar spectrum in four seasons (spring, summer, autumn and winter), and under the environment that the simulated light spectrum is close to the real solar spectrum, the physiological rhythm of the human body can not be influenced.
That is to say, the color temperature point of the color temperature light source 10 can be adjusted to shift to other color temperature directions by adjusting the addition of the light source group 20, so that the color temperature light source 10 has a continuous color temperature, and the lighting module 100 has a continuous color temperature, thereby ensuring that the emission spectrum of the lighting module 100 is close to the spectrum of real sunlight.
Specifically, the adjusting light source set 20 includes a red light source 201 and a green light source 202. The hybrid light source 60 includes a first sub-hybrid light source 601. The color temperature of the second color temperature point P2 is lower than the color temperature of the first color temperature point P1.

The color temperature of the second color temperature point P2 of the first sub-mixed light source 601 is lower than that of the first color temperature point P1, and the second color temperature point P2 falls on 3000K of the planckian black body radiation curve. In other implementations, the second color temperature point P2 may not be limited to 3000K as long as the color temperature of the second color temperature point P2 is lower than the first color temperature point P1. The selected first color temperature point P1 may not be limited to 4000K, and may be any color temperature point among 2700K, 3000K, 5000K, 5700K, 6500K, and the like. The brightness of the red light source, the brightness of the green light source 202, the brightness of the first adjusting light source 30, and the brightness of the color temperature light source 10 are adjusted by adjusting the current duty ratio.
The modulated light source bank 20 further includes a blue light source 203. The hybrid light source 60 further includes a second sub-hybrid light source 602. The color temperature of the third color temperature point P3 is higher than that of the first color temperature point P1.

The second sub-mixed light source 602 having the third color temperature point P3 is obtained by adjusting the luminance of the color temperature light source 10 and the luminance of the second adjusting light source 40.
Therefore, the third color temperature point P3 with a color temperature higher than the first color temperature point P1 and on the planckian black body radiation curve L can be obtained by adjusting the brightness of the blue light source 203, the brightness of the green light source 202, and the brightness of the second adjusting light source 40 and the color temperature light source 10.
The blue light source is approximately located at B (1.15, 0.15 point in color coordinates, in one embodiment, the first color temperature point P1 is selected to be 4000K, the brightness of the blue light source 203 and the brightness of the green light source 202 are adjusted by mixing the brightness of the blue light source 203 and the green light source 202 and adjusting the current to obtain the second adjusted light source 40, the brightness of the second adjusted light source 40 and the brightness of the color temperature light source 10 are then adjusted by mixing the second adjusted light source 40 and the color temperature light source 10 and adjusting the current to obtain the second sub-mixed light source 602, the color temperature of the third color temperature point P3 of the second sub-mixed light source 602 is higher than that of the first color temperature point P1, and the third color temperature point P3 falls on 6500K of the planckian black body radiation curve L, in other embodiments, the third color temperature point P3 may not be limited to 6500K, as long as the first color temperature point P1 is higher than the first color temperature point P1, the color temperature point can be 2700K, 3000K, 5000K, 5700K, 6500K or the like. The brightness of the blue light source 203, the brightness of the green light source 202, the brightness of the second adjusting light source 40, and the color temperature light source 10 can be adjusted by adjusting the current duty ratio.
Therefore, when the second color temperature point P2 and the third color temperature point P3 on both sides of the first color temperature point P1 are both available, and the second color temperature point P2 and the third color temperature point P3 are both located on the planckian black body radiation curve L, the color temperature adjustable lighting module of the present invention can make the color temperature points continuous, and further the newly generated color temperature points of the lighting module 100 can generate new spectra, which can make up for the missing partial spectra of the lighting module 100 due to the process problems, and solve the technical problem of the lighting module 100 that the missing of the color temperature points and the missing partial spectra cause the influence on the circadian rhythm of the human body. In the present embodiment, the determination of the positions of the color temperature points for the above color temperature light source 10, red light source 201, green light source 202, and blue light source 203 is as follows. Further, after the positions of the color temperature points of the color temperature light source 10, the red light source 201, the green light source 202 and the blue light source 203 are determined, the chromaticity of the light sources can be determined.
For the monochromatic light source, the chromaticity diagram can be represented by color coordinates (x, y, z), which represent the color and chromaticity of the white light and the colored light, and the chromaticity diagram is represented by (x, y) in fig. 2, and another value z is 1-x-y, and its chromaticity XYZ and color coordinates XYZ are calculated as follows:
x/X＝y/Y＝z/Z (1)
XYZ is expressed by three theoretical values based on RGB (the standard three primary colors red, green and blue represented by R, G and B), where Y corresponds exactly to the brightness of the light-emitting object, i.e., P
Then, from equation (1), it is possible to obtain:
X＝Y/y*x
Y＝P
Z＝Y/y*(1-x-y) (2)
(2) x, Y, Z in the formula can represent the chromaticity of each color light or white light, and the chromaticity of the color light or white light can be adjusted by adjusting the luminance. According to the color coordinates, the positions of the color temperature points of the color temperature light source 10, the red light source 201, the green light source 202 and the blue light source 203 on the chromaticity diagram and the position on the planckian black body radiation curve L can be determined, and meanwhile, the chromaticities X, Y, Z of the color temperature light source 10, the red light source 201, the green light source 202 and the blue light source 203 can be determined according to the color coordinates.
When two or more light sources are mixed, for example, the red light source 201, the green light source 202, and the blue light source 203, the chromaticities X ', Y ', Z ' of the mixed light sources are as follows:
X’＝X1+X2+X3+…
Y’＝Y1+Y2+Y3+…
Z’＝Z1+Z2+Z3+… (3)
the total brightness after mixing is P'
P’＝P1+P2+P3+… (4)
(3) In the formula, X ', Y ', Z ' may represent chromaticity of each of the modulated light or the mixed light. The color coordinates (x, y, z) of the adjusted light or the mixed light can be inversely derived according to the chromaticity, and the positions of the color temperature points of the first adjusted light source 30, the second adjusted light source 40, and the mixed light source 60 on the chromaticity diagram and the planckian black body radiation curve L can be determined.
In other words, in the present application, any coordinate point within a triangular range enclosed by a connecting line of three points R, G, B shown in fig. 2 can be adjusted by mixing light of the red light source 201, the green light source 202, and the blue light source 203 and adjusting the brightness of the red light source 201, the green light source 202, and the blue light source 203, and then different color temperature values on a corresponding planck black body radiation curve can be adjusted by mixing light with the color temperature light source 10 and adjusting the brightness of the color temperature light source 10, so as to adjust the color temperature of the color temperature light source 10 with discontinuous color temperature points, so as to obtain the illumination module 100 with continuous color temperature points. In the present embodiment, the lighting module 100 can achieve a color temperature change from 2700K to 6500K, and the spectral distribution is close to the ratio of the solar spectrum.
Meanwhile, in the prior art, the realization of simulating the solar spectrum is generally realized by superposing a plurality of LED lamp beads with different wavelengths to simulate the solar spectrum, the current duty ratio of each LED lamp bead is controlled to ensure that the luminous brightness of different wavelengths is different, the proportion of different wave bands of the whole spectrum is controlled, and the whole spectrum is close to the solar spectrum. However, since the monochromatic LED has a narrow wavelength band, generally only 20nm wide, as shown in fig. 4, to realize spectrum superposition of a 430nm-780nm band of a solar spectrum, spectrum superposition of a plurality of different monochromatic LED beads is required, so that current control of the whole lighting system becomes complicated, and the space occupied by the plurality of beads is large, and miniaturization cannot be realized. And because monochromatic light has wave crests, the spectrum of a plurality of LED lamp beads with different monochromatics cannot be smoothly and continuously realized after the spectrum is superposed, the difference with the solar spectrum to be realized is large, and the color rendering index cannot reach a high level. The required luminescent spectrum can be simulated by mixing the red light source 201 with the wavelength range of 600-620nm, the green light source 202 with the wavelength range of 500-520nm, the blue light source 203 with the wavelength range of 450-480nm and the color temperature light source 10 with the similar solar spectrum (discontinuous color temperature) and adjusting the brightness of the red light source 201, the green light source 202, the blue light source 203 and the color temperature light source 10, so that the technical problems that the current control of the lighting system is complex, the occupied space of a plurality of lamp beads is large and the miniaturization cannot be realized are solved, the simulated luminescent spectrum is smooth and continuous, the difference with the solar spectrum to be realized is small, and the color rendering index level is high. Furthermore, the color temperature point obtained by the method is on or near the Planck black body radiation curve L, and the color tolerance is within 7 steps; and the simulated luminescence spectrum is close to the real solar spectrum.
Further, the adjusting light source sets 20 can be plural, and the plural adjusting light source sets 20 are arranged at intervals. Specifically, in order to further enable the simulated light emission spectrum to approach the real solar spectrum, a plurality of adjusting light source sets 20 may be provided to mix light, and adjust the brightness to simulate the light emission spectrum closer to the real solar spectrum.
Referring to fig. 5, the present invention provides a color temperature adjusting method for an illumination module, including:
step S1, providing a color temperature light source 10 and an adjusting light source set 20, wherein the color temperature light source 10 includes a first color temperature point P1 with discontinuous color temperature on the planck black body radiation curve L.
In step S2, the luminance ratio of the color temperature light source 10 and the adjusted light source set 20 is adjusted based on the first color temperature point P1 to obtain the mixed light source 60, where the mixed light source 60 includes a second color temperature point P2 and a third color temperature point P3 located at two sides of the first color temperature point P1, and the second color temperature point P2 and the third color temperature point P3 are both located on the planck black body radiation curve L.
Therefore, in the color temperature adjustment method of the lighting module, the second color temperature point P2 and the third color temperature point P3 which are located on the planck black body radiation curve L and located on the two sides of the first color temperature point P1 are formed, and then the first color temperature point P1, the second color temperature point P2 and the third color temperature point P3 enable the color temperature points of the lighting module 100 on the planck black body radiation curve to be continuous, so that the newly generated color temperature points of the lighting module 100 can generate new spectrums, a part of spectrums of the lighting module 100 missing due to process problems can be compensated, and the technical problem that the lighting module has influence on the physiological rhythm of the human body due to the missing of the color temperature points and the missing of the part of spectrums is solved.
Referring to fig. 6, in one embodiment, step S2 includes the following steps:
in step S21, the brightness of the red light source 201 and the green light source 202 of the adjusted light source group 20 is adjusted to obtain the first adjusted light source 30, wherein the color temperature point of the first adjusted light source 30 is outside the planckian black body radiation curve L.
In step S22, the brightness of color temperature light source 10 and the brightness of first adjusted light source 30 are adjusted to obtain first sub-mixed light source 601 of mixed light source 60 including second color temperature point P2, where the color temperature of second color temperature point P2 is lower than the color temperature of first color temperature point P1.
Therefore, the second color temperature point P2 of the planck black-body radiation curve L with a color temperature lower than the first color temperature point P1 can be obtained by adjusting the brightness of the red light source 201, the green light source 202, the first adjusting light source 30 and the color temperature light source 10.
Referring to fig. 7, in another embodiment, step S2 includes the following steps:
in step S23, the brightness of the blue light source 203 and the green light source 202 of the adjusted light source group 20 is adjusted to obtain the second adjusted light source 40, wherein the color temperature point of the second adjusted light source 40 is outside the planckian black body radiation curve L.
In step S24, the brightness of the color temperature light source 10 and the brightness of the second adjusting light source 40 are adjusted to obtain the second sub-mixed light source 602 of the mixed light source 60 having the third color temperature point P3, wherein the color temperature of the third color temperature point P3 is higher than the color temperature of the first color temperature point P1.
Therefore, the third color temperature point P3 with a color temperature higher than the first color temperature point P1 and on the planckian black body radiation curve L can be obtained by adjusting the brightness of the blue light source 203, the brightness of the green light source 202, and the brightness of the second adjusting light source 40 and the color temperature light source 10.
Therefore, when the second color temperature point P2 and the third color temperature point P3 on both sides of the first color temperature point P1 are both available, and the second color temperature point P2 and the third color temperature point P3 are both located on the planckian black body radiation curve L, the color temperature adjusting method of the lighting module can make the color temperature points continuous, so that the color temperature points newly generated by the lighting module 100 can generate new spectra, can make up for part of the spectra lost by the lighting module 100 due to process problems, and solves the technical problem that the lighting module has influence on the circadian rhythm of the human body due to the loss of the color temperature points and the loss of part of the spectra.
