Specifically, the spectral data generated when each LED in the LED driving circuit operates independently, that is, the spectral data generated by the light of a single color, may be measured first. Under the condition that the total output luminous flux is the same, the color rendering index and the luminous efficiency can reach the optimal duty ratio combination under the common color temperatures, and the data are stored in the controller. When the system operates, the controller can compare the monitored light condition with the target lighting condition, firstly adjusts and controls the color temperature, each channel strictly performs light supplement according to the measured proportion, and then the same side of each channel is adjusted to control the illumination.
Specifically explaining the structure of the power supply switching circuit, the power supply switching circuit includes: the power supply comprises a first power switch switching chip, a second power switch switching chip, a first capacitor, a second capacitor, a third capacitor and a fourth capacitor; the input end and the enabling end of the first power switch switching chip are electrically connected with the current output end of the rectifying circuit; the input end and the enabling end of the second power switch switching chip are both connected with the output end of the standby power supply; the output end of the first power switch switching chip is connected with the output end of the second power switch switching chip and is electrically connected with the color temperature monitoring part, the illumination monitoring part, the lighting part and the current input end of the controller; the first end of the first capacitor is connected between the current output end of the rectifying circuit and the input end of the first power switch switching chip, and the second end of the first capacitor is grounded; the first end of the second capacitor is connected with the output end of the first power switch switching chip, and the second end of the second capacitor is grounded; the first end of the third capacitor is connected between the output end of the standby power supply and the input end of the second power switch switching chip, and the second end of the third capacitor is grounded; the first end of the fourth capacitor is connected with the output end of the second power switch switching chip, and the second end of the fourth capacitor is grounded.

When the input 220V alternating current commercial power is higher than a preset voltage value, the voltage dependent resistor is conducted instantly, all current flows through the voltage dependent resistor, and the fuse is fused to protect the power supply circuit. The thermistor can inhibit surge current generated at the moment of starting the circuit, and then through the continuous action of the current, the reduction of the resistance value of the thermistor becomes very small, and the normal working current of the power supply circuit cannot be influenced, so that the power supply circuit is further protected.
In order to filter the charging voltage to eliminate the noise signal in the charging voltage, the method further includes: a filter circuit; the current input end of the filter circuit is electrically connected with the current output end of the power supply switching circuit, and the current output end of the filter circuit is electrically connected with the current input ends of the color temperature monitoring component, the illumination monitoring component, the lighting component and the controller.
Specifically explaining the structure of the filter circuit, the filter circuit includes: the third diode, the first resistor, the second resistor, the fifth capacitor, the sixth capacitor, the third resistor and the seventh capacitor; the anode of the third diode, the first end of the first resistor and the first end of the second resistor are connected in common and are electrically connected with the current output end of the power supply switching circuit, the second end of the first resistor and the second end of the second resistor are electrically connected with the first end of the fifth capacitor, and the cathode of the third diode is connected in common with the second end of the fifth capacitor and is electrically connected with the first end of the sixth capacitor, the first end of the third resistor and the first end of the seventh capacitor; and the second end of the sixth capacitor, the second end of the third resistor and the second end of the seventh capacitor are connected in common and electrically connected with the current input ends of the color temperature monitoring part, the illuminance monitoring part, the lighting part and the controller.
In this embodiment, the color temperature monitoring unit and the illuminance monitoring unit are four-channel color sensors TCS3414CS produced by AMS, which can accurately measure the chromaticity of light with different intensities and output the light with 16-bit resolution. The device has a cmos integrated circuit with 8 x 2 array filtering photodiodes, analog to digital converters and control functions, with 4 red filters, 4 green filters, 4 blue filters and 4 no filters in 16 photodiodes. The corresponding color temperature and illumination value can be converted by matrix operation on the corresponding numerical value of the red, green and blue three-channel integral, and the corresponding color temperature and illumination value can be used as the parameter for adjusting the color temperature and the illumination. The lighting component is composed of a multi-chip LED product Xlamp MC-E of Cree. The LED single particle is internally packaged with four LED chips with different colors, namely red light, green light, blue light and white light, the single maximum input power is up to 2W, and the luminous intensity can be independently adjusted. The controller is an eight-bit microcontroller that generates four independent PWM signals, each group controlling the light output of the LEDs of different colors. The PWM frequency is set to 1kHz, which is not noticeable to the human eye, and the duty ratio value is 8-bit data. The LED driving circuit adopts a dual-channel linear LED driving chip AL1792 of Diodes. A total of 4 multi-chip LEDs are used, and LEDs with the same color in each LED chip are connected in series and then connected to one channel of the driving chip. The resistor is designed and selected to be X omega, and the maximum output current of each path of LED is 500 mA. Because the conduction voltage drops of the four color chips are respectively 2.3V (R), 3.7V (G), 3.5V (B) and 3.5V (W), the maximum output power of a single system is 26W, and the controller generates different duty ratio combinations to control the output. The standby power supply is a storage battery. The model of the first power switch switching chip and the model of the second power switch switching chip are both HX 9001. When the main power source is powered off, the power supply can be switched to the standby power source through the power switching circuit, so that the color temperature and the illumination of each partition in a classroom under the power failure state are guaranteed to meet the requirements, and the teaching work under the power failure state can still be normally carried out and still can effectively protect eyes of teachers and students.
