Abstract

The invention discloses an ambient light sensing controller based on an LED lamp, which includes a microcontroller, a voltage stabilizing circuit and a light detection circuit. The voltage stabilizing circuit is connected with an LED driving circuit and provides working voltage to the microcontroller and the light detection circuit; A PWM port is set on the microcontroller, and the microcontroller is also connected to and drives the light control switch through the PWM port. At the same time, the illuminance change value detected by the light detection circuit is converted into an electrical signal and compared with the preset voltage value, and then the switch and brightness adjustment of the LED are controlled through the PWM port according to the comparison result. The invention realizes the function of automatic control of the lamp according to the change of ambient light, saves a lot of manpower and energy; realizes the purpose of installing the light sensor controller on any part of the lamp, and the product experience is very good.

Description

technical field [0001] The invention relates to the technical field of light control equipment, in particular to an ambient light sensing controller based on LED lights. Background technique [0002] The light sensor controller of the lamp can realize the automatic control that the lamp is not on during the day and automatically turns on when it is dark. It is a very practical and convenient product. However, the traditional light-sensing controller cannot recognize the luminous light of the lamp itself and the visible light of the environment, that is to say, it cannot distinguish whether it is day or night when it is interfered by its own light. The installation of lamps is subject to many restrictions, causing great trouble; and this method cannot achieve accurate constant light lighting, cannot accurately avoid self-light interference, and recognize the intensity of ambient light to make light compensation. [0003] The popularity of LED solid-state lighting provides a ...
