Among them, the LED light source module 2 includes four independent light sources of red, green, blue, and white, which are respectively connected to the LED driving circuit. Specifically, the processor converts the graphic data into RGB data, and based on factors such as hue type, power, etc., and combines a specific formula to output four-channel PWM signals of red, green, blue, and white to control the LED driving circuit. The LED driving circuit is used to receive the four-channel PWM signals of red, green, blue, and white output by the processor, respectively adjust the current values of the four-channel lights, and finally the mixed light effect of different brightness values of the four-channel lights is consistent with the specific ambient light required by the collected graphic. The specific implementation method of self-adaptation is as follows:

[0035] Step S1: Color sampling is performed on the space of the object to be illuminated through a camera sensing device to obtain spatial image data; Step S2: The spatial image data is cropped and matched according to the actual light-emitting angle of the LED light-emitting module so that the cropped spatial image data is consistent with the angle of the LED light-emitting module, and then the spatial image data is converted into RGB color data; Step S3: The obtained RGB color data is subjected to partition processing, and weighted averaging is performed according to the RGB color space values of each pixel point in the color sampling area to determine the target color space RGB value of the color sampling area; Step S4: The obtained target color space RGB value is subjected to power configuration conversion to obtain the power values of the four colors of RGBW. Step S5: The power values of the four colors of RGBW are converted into duty cycle data values for output to adjust the light-emitting intensity and spectral characteristics of the LED lighting device. Specifically, in the embodiment of the present application, an image of the spatial environment of the object to be illuminated is obtained through a camera sensing device, and the image data is sheared according to the actual light-emitting angle of the LED light-emitting module so that the image data is matched with the light-emitting angle of the LED light-emitting module. By processing the RGB color space values of each pixel point in the color sampling area, the target color space value is determined, thereby improving the accuracy of color acquisition; The LED light source module 2 is composed of an independent white light LED and RGB three-color LEDs, forming an RGBW 4-channel independent control; Through power conversion of the obtained RGB color data, it is ensured that the actual output power of RGB and the actual output power of white light are normalized, and it is specified that the minimum power of white light is not less than 80% to ensure the energy of basic white light illumination. Complementary processing is performed on the RGB power and the white light power so that the actual output power data of each LED lighting device is consistent, and then the embodiment of the present application can automatically adjust the spectral characteristics of the LED lighting device when switching between different objects to be illuminated, without the need to rely on other wireless devices or control devices, simplifying the system structure and reducing the cost.

[0036] Among them, the image collected by the camera sensing device in step S1 is data with a 60D angle of a 16:9 rectangle, and the spatial image data corresponding to the length and width is cropped according to the ratio of the angles in step S2. Among them, the partition processing method in step S3 is: equal-proportion partition in the length and width directions of the rectangular data area; In step S1, color sampling is performed on the space of the object to be illuminated through a camera sensing device to obtain spatial image YCbCr data.

[0037] The spatial image YCbCr data obtained in step S1 is cropped so that the cropped image data is consistent with the angle of the LED light-emitting module; The cropped spatial image YCbCr data is converted into RGB data through the following formula, and the formula principle is the standard color space conversion relationship.

[0038] R = 1.164 * (Y - 16) + 1.596 * (Cr - 128);

[0039] G = 1.164 * (Y - 16) - 0.813 * (Cr - 128) - 0.392 * (Cb - 128);

[0040] B = 1.164 * (Y - 16) + 2.017 * (Cb - 128).

[0041] In step S3, the RGB color data is partitioned, and at least one color sampling area is determined in the image. The color sampling area is used to represent a part of the image area delimited on the image; according to the RGB color space values of each pixel point in the color sampling area, the average hue value corresponding to the color sampling area is determined. Further, in Embodiment 3 of the present application, when partitioning, three color sampling areas a, b, and c are formed. The RGB data of the pixel points in each color sampling area is weighted and averaged to obtain the RGB color average value of each area. Based on the color average value, the color weight corresponding to the RGB color space value of each pixel point area is determined; according to the RGB color space value and the color weight, the target color space value of the color sampling area is determined;

[0042] When the deviation of the color value (0 - 255) of each color in the RGB color data RGB of the three color sampling areas a, b, and c is within 10%, it is considered that the color weights of the three color sampling areas a, b, and c are similar, and then the RGB color data of the three areas is weighted and averaged to obtain the target color space value of the color sampling area;

[0043] When the deviation of the color value (0 - 255) of two colors in the RGB color data RGB of the three color sampling areas a, b, and c is within 10%, and the deviation of one color exceeds 10%, then the RGB color data of the two similar areas is weighted and averaged, and the RGB data of the area with a deviation exceeding 10% is discarded to obtain the target color space value of the color sampling area;

[0044] When the color values (0 - 255) of the RGB color data of the three color sampling areas a, b, and c all exceed the 10% deviation range, it is considered that the color weights of the three color sampling areas a, b, and c are not similar, and then the RGB color data of the three color sampling areas a, b, and c is weighted and averaged to obtain the target color space value of the color sampling area.

[0045] In the embodiment of the present application, the target color space value of the color sampling area is calculated using the color weights of all pixel points on the color sampling area, ensuring that the color of the collected image can be closer to the actual image color, effectively improving the quality of image color acquisition.

[0046] The method for converting the obtained target color space RGB values into power values of the four colors RGBW is as follows:

[0047] Pr = (R * BASE_POWER_R) / 255;

[0048] Pg = (G * BASE_POWER_G) / 255;

[0049] Pb = (B * BASE_POWER_B) / 255;

[0050] Prgb = Pr + Pg + Pb;

[0051] When Prgb ≤ BASE_POWER_RGB (Condition 1), it satisfies Ptotal = Prgb + Pw, Pw = K * BASE_POWER_W, where K is the adjustment coefficient of the white light power;

[0052] Obtain the actual power values of the four LED light sources RGBW;

[0053] When Prgb > BASE_POWER_RGB (Condition 2), Pr, Pg, and Pb are proportionally compressed until Condition 1 is satisfied, and then execute according to Condition 1;

[0054] The set value of BASE_POWER_RGB is 20% of Ptotal; Ptotal is the total power of the LED light source module 2;

[0055] Among them, Prgb represents the actual total power of the three colors RGB, Pr represents the power of the red light, Pg represents the power of the green light, Pb represents the power of the blue light, and Pw represents the power of the white light;

[0056] BASE_POWER_R, BASE_POWER_G, and BASE_POWER_B are the powers of the fixed red, green, and blue light sources respectively, BASE_POWER_W is the power of the fixed white light source, and BASE_POWER_RGB is the total power of the fixed red, green, and blue light sources.

[0057] Among them, the color weight refers to the contribution value of each pixel point in the color sampling area when calculating the color of the sampling area; it is used to adjust the energy relationship between the white light and the RGB lights, which not only ensures the illuminance value on the illuminated object for the white light basic lighting, but also reflects and restores the color of the illuminated object at the same time, making the main color weight part of the illuminated object more prominent and the different color weight parts more distinct.

[0058] Among them, the method for converting the power values of the four colors RGBW into duty cycle data values in step S5 is as follows: the duty cycle data range is 0 - 255;

[0059] R: 255 * Pr / BASE_POWER_R;

[0060] G: 255 * Pg / BASE_POWER_G;

[0061] B: 255 * Pb / BASE_POWER_B;

[0062] W: 255 * Pw / BASE_POWER_W.

[0063] Under the above settings, when the actual total power of the RGB three colors is less than or equal to 20% of the preset total power, directly add the RGB power values and the white light power values to obtain the total power value; when the actual total power of the RGB three colors is greater than 20% of the preset total power, proportionally compress the RGB power values until the above conditions are met; at the same time, there is also a step of limiting that the minimum power of the white light is not less than 80% of the total power to ensure the brightness of the basic lighting; that is, in the fourth embodiment of the present application, by limiting that the minimum power of the white light is not less than 80% of the total power, the uniformity and comfort of the basic lighting are ensured, and at the same time, through the power adjustment of the four colors of RGBW, the self - adaptation of the spectrum is realized.
