Background technique

With the development and maturity of LED technology, LED, as a powerful tool for advertising and decoration, has become more and more popular, and has become an indispensable beautiful landscape for logo publicity and urban beautification.

As high-tech products, LED lighting products are widely used in municipal lighting, architectural lighting, landscape lighting, stage lighting, teaching lighting and other fields. Traditional LED light sets mainly use commercial power as the power supply. With the development and use of new energy sources, solar energy gradually enters the field of lighting. During the day, the light energy is converted into electrical energy through the solar panel, and the lithium battery is charged to supply power to the LED light group at night. The charging time of the solar panel to the lithium battery, and the control of the power supply time of the lithium battery to the LED light group are mainly controlled by the timer, and it is impossible to adjust the charging time and the lighting time of the LED light group by itself in the case of sudden changes in light conditions. . In order to adapt to sudden changes in light, some manufacturers use light sensors for control. However, due to the high sensitivity of light sensors, false triggers are prone to occur, and the control of LED light sets is unstable.

When the lamp does not need to be lit, the microwave part of the circuit does not need to work. In order to save power, the PWM_D signal is added to turn off the microwave circuit. Insufficient electric energy effectively prolongs the time of turning on the light, becomes an urgent problem to be solved.
