In recent years, the continuously improved technical level has promoted the improvement of LED light efficiency, the enrichment of light color, the improvement of color rendering, the reduction of junction temperature and thermal resistance, and the large-scale mass production has also greatly reduced the price of LED light sources. As a new generation of green lighting source, LED lighting has unique advantages such as high efficiency, energy saving, environmental protection, long service life, and easy maintenance. It will become another huge leap in the history of human lighting after incandescent lamps and fluorescent lamps. With the help of the 2014 Nobel Prize in Physics for LED lighting, LED will usher in a new round of rapid development and will develop in the direction of higher light efficiency, higher reliability, lower power consumption, lower cost, and more intelligent. In the existing LED lamp light source, the mixed light distribution technology is basically mixed and matched by two to three light sources, which results in the total power and total luminous flux of the light source being not large enough, and the number of light color categories mixed is small, and it cannot be adjusted in certain specific parameters of the light color, which has certain limitations. In order to solve the above problems, this embodiment discloses a lighting method based on a multi-primary color light source.

[0097] Determine the output ratio of each basic light color by matching the basic light colors corresponding to each color temperature level;

[0098] The output ratio of each color temperature level to each basic light color is confirmed as the matching result.

[0099] The beneficial effect of the above technical solution is that by determining the output ratio of each basic light color, the output ratio of each basic light color in the mixed light can be intuitively determined, laying a foundation for the subsequent work of color temperature matching the mixed light.

[0100] In one embodiment, obtaining a required color temperature, and selecting a target matching result from matching results for lighting according to the required color temperature includes:

[0101] Determine the required color temperature based on the environmental parameters of the target space;

[0102] Determining a target level of the required color temperature within the color temperature level;

[0103] According to the target level, select the target output ratio of each basic light color corresponding to the target level in the matching result;

[0104] An electromagnetic wave signal of each basic light color is generated according to a target output ratio of each basic light color to illuminate a target space within the electromagnetic wave emission range of the multi-primary color light source.

[0105] The beneficial effects of the above technical solution are: the color of the mixed light corresponding to the required color temperature can be accurately matched, and then the target space can be illuminated within its illumination range in the form of electromagnetic waves. The color of the mixed light can be quickly determined by color temperature matching, and then rapid and stable lighting can be performed, thereby improving lighting efficiency, work efficiency and lighting stability.

[0106] In this embodiment, generating an electromagnetic wave signal of each basic light color according to the target output ratio of each basic light color to illuminate the target space within the electromagnetic wave emission range of the multi-primary color light source includes:

[0107] Constructing a light response channel for each basic light color, and determining a light color component according to a target output ratio of the basic light color;

[0108] Constructing a light color spectrum of the target space according to the environmental parameters, and determining a linear compensation amount for each basic light color based on the light color spectrum;

[0109] The expected electromagnetic wave emission power of each basic light color is determined according to the linear compensation amount of each basic light color:

[0110]

[0111] Among them, Q i2 Expressed as the expected electromagnetic wave emission power of the i-th basic light color, Q i1 It is expressed as the initial electromagnetic wave emission power of the i-th basic light color, E i It is expressed as the mapping accuracy of the illumination response channel corresponding to the i-th basic light color, k iIt is expressed as the response coefficient of the illumination response channel corresponding to the i-th basic light color, F i1 Expressed as the basic light color component of the i-th basic light color, F i2 Expressed as the linear compensation amount of the i-th basic light color, α i It is expressed as the light correction coefficient of the i-th basic light color;

[0112] An electromagnetic wave signal of each basic light color is generated according to the expected electromagnetic wave emission power of the basic light color to illuminate the target space within the electromagnetic wave emission range of the multi-primary color light source.

[0113] The beneficial effects of the above technical solution are: by calculating the expected electromagnetic wave emission power of each basic light color, the output ratio of each basic light color can have a sufficient proportion in the color temperature to ensure the lighting effect and color temperature effect, thereby improving practicality. Furthermore, by performing linear compensation on each basic light color, the compensated light amount can be more in line with environmental needs, thereby improving compatibility and further improving practicality.

[0135] In one embodiment, the multi-primary color light source includes: a red light source, a green light source, a blue light source, a yellow light source and a white light source.

[0136] This embodiment also discloses a lighting system based on a multi-primary color light source, such as Figure 4 As shown, the system includes:

[0137] A setting module 401 is used to set the electromagnetic wave emission range of the multi-primary color light source;

[0138] The adjustment module 402 is used to adjust the photoelectric conversion parameters of each light source after the setting is completed;

[0140] The lighting module 404 is used to obtain the required color temperature, and select a target matching result from the matching results for lighting according to the required color temperature.

[0141] The working principle and beneficial effects of the above technical solution have been described in the method claims and will not be repeated here.

[0142] In one embodiment, the technical solution provides a white light source based on a multi-color light source (blue / red / yellow / green) that can be matched with different color temperature ranges. First, through a group of multi-way power supply controllers, the photoelectric conversion parameters of each light source are adjusted to achieve the light source lighting effect required by the relevant requirements, and make the light source emit all light colors in the visible light band of the naked eye, and even simulate the lighting data of seasons and sunshine to meet lighting needs.

[0143] The principle of the front-end power drive control technology is as follows: the overall architecture includes three parts: AC-DC, DC-DC and control unit. Compared with the integrated design structure, the current modular design architecture has stronger compatibility and wider versatility, and is also convenient for subsequent maintenance. In the process of mixing light, the optical characteristics of each light source of multi-primary colors largely depend on the magnitude of the current flowing through it. The AC-DC output is a constant voltage source characteristic, and its current magnitude is determined by the load characteristics. If the light source is directly connected to the AC-DC output end, the current will be uncontrollable or follow its volt-ampere characteristics. Since the multi-primary color light source contains multiple independent LED chips, each LED chip needs to be powered independently and the current is adjustable. In view of this, a DC-DC constant current control unit is added. The unit converts the constant voltage source into a constant current source with adjustable current. The drive load voltage depends on the input voltage. The drive current adopts PWM control, while taking into account the current adjustable characteristics and LED heat dissipation balance. The PWM signal is generated by the single-chip microcomputer, and the corresponding control command can be issued by an external remote control or switch according to the demand. After receiving the relevant instructions, the single-chip microcomputer generates the corresponding PWM signal to control the DC-DC driver chip to output the required current, so as to adjust the photoelectric conversion parameters of each group of primary color light sources, so that the light colors of various primary colors can reach the light parameters of the required lighting. The working principle diagram is as follows Figure 5 As shown;

[0144] After adopting the technical means, through the power drive control end, we can control the electromagnetic wave range of five light sources, blue, yellow, red, green, and white, and adjust the photoelectric parameters. By adjusting the matching ratio of each basic light color through multiple power supplies, light of different color temperatures, such as 1000K-9000K, the color temperature of each stage range and the matching ratio of the five light colors are differentiated. When the color temperature we need is 2000K, the power drive controller is used to adjust the five-way output ratio, and the blue, green, and white are adjusted to zero output, and the output ratio of red and yellow is 1:1. In this output mixed environment, light color lighting with a color temperature of 2000K can be obtained. Continue to adjust, the output ratio of red and yellow is 1:1.1. In this output mixed environment, light color lighting with a color temperature of 2200K can be obtained (the relative spectrum is as follows); at the same time, through photoelectric parameter regulation and control of the electromagnetic wave range of the light source, the color rendering index is adjusted for light colors with the same color temperature. The above data are only embodiments given for explaining the present invention and do not constitute a limitation to the present invention. In practical applications, the ratio can be adjusted according to development needs.

[0145] Through the technical solution of the present invention, a flexible and simple structure can be achieved, and the light source can be adapted to a great extent according to the use space. At the same time, due to the wide variety of light colors, the light colors required for different scenes can be customized, which improves the user experience and practicality. Furthermore, various parameters of the light color can be adjusted as needed, including light effect, color temperature, and color rendering index, thereby improving control stability.
