The AC-DC circuit (1) provides direct current power supply for a lamp system, the capacity of storing electric energy is utilized, when the power supply is turned off, the voltage on the capacity can be kept for a little time, at the moment, a power failure detection circuit (3) and a three-primary color microprocessor MCU circuit (4) can continue to work, the power failure detection circuit (3) detects that the power supply is turned off and sends a message to the microprocessor MCU, the microprocessor MCU realizes the setting of lamp STATE information (L-STATE) according to the time between the turning on and the turning off, and stores the current RGB parameters and the STATE information (L-STATE) of the LED lamp into an EEPROM, when the power supply is turned on, the RGB parameters and the STATE information (L-STATE) of the LED lamp in the EEPROM are read, the three-primary color microprocessor MCU circuit (4) outputs three paths of PWM to a three-primary color LED drive circuit (5), and finally the working current of the three-primary, thereby achieving color control.

An AC-DC circuit (1) part: alternating current and direct current voltage conversion, wherein the input is alternating current, the input can be high voltage (AC110V or AC220V), and the input can also be low voltage (such as AC 12V or AC 24V), and the output direct current voltage VCC is used for supplying power to the LED lamp system.

A DC-DC circuit (2) part: the method is a direct current voltage conversion method, an input direct current voltage VCC is converted into direct current voltages VDD for work of a power failure detection circuit (3), a three primary color microprocessor MCU circuit (4) and the like, VCC-VDD is preferably more than or equal to 2V, so that a stable output voltage VDD can be obtained, and capacitors C1 and C2 have proper and sufficiently large capacity, so that when the power failure occurs, the voltage of the point A is reduced from VCC to power failure, the VDD voltage can be kept for a certain time, and the microprocessor MCU has sufficient time to store RGB parameters and STATE information (L-STATE) of an LED lamp in the power failure to an EEPROM.

The power failure detection circuit (3) part: when the voltage of the point A is detected to be reduced from VCC and power down, a message is sent to a three-primary-color microprocessor MCU circuit (4), the microprocessor MCU starts a three-primary-color closing work flow, and RGB parameters and STATE information (L-STATE) of an LED lamp during power down are stored in an EEPROM.

The present invention employs a Pulse Width Modulation (PWM) technique, which is a very efficient technique for controlling an analog circuit using the digital output of a microprocessor. And the microprocessor MCU outputs PWM to control whether the light-emitting diode light source emits light or not and the intensity of the light emission. When energized, the LED emits light, the intensity of which is controlled by the pulse width. In one working period, the pulse width determines the conduction time of the LED current, the conduction time is long, the current is large, and the brightness of the LED is high. The LED brightness parameter is set by the MCU, and the control range is 2^aIf a is 9, then it is 2⁹512, i.e. the control range mayUp to 512 levels of luminance, i.e. 0-511, corresponding to binary 000000000-.

Therefore, the on-off and the size of the current of each electrode of the LED can be controlled in a digital form, and the LED light source does not emit light and has luminous intensity. Due to the human visual persistence characteristic, the frequency of the modulation pulse PWM output by the microprocessor MCU is more than or equal to 10KHz, thereby keeping the lighting effect of the lamp.
