Abstract

The invention discloses an intelligent light-controlled linear LED lamp circuit, comprising a rectification circuit, a light induction circuit, an intelligent control circuit, a voltage stabilizing circuit, a multi-section constant current circuit, a first LED light-emitting circuit, a second LED light-emitting circuit and a third LED Light-emitting circuit, the intelligent control circuit is provided with a voltage threshold, when the intelligent control circuit is in sleep mode, none of the first LED light-emitting circuit, the second LED light-emitting circuit and the third LED light-emitting circuit emit light, and the intelligent control circuit is in normal state. In the working mode, the intelligent control circuit outputs the PWM control signal, and the multi-stage constant current circuit controls whether the first LED light-emitting circuit, the second LED light-emitting circuit and the third LED light-emitting circuit emit light under the control of the PWM control signal; the advantage is that the cost is relatively low Low, on the basis of realizing the two automatic control functions of turning on and turning off the lights, it can use the ambient light intensity as a reference time point to automatically adjust the brightness according to the preset time stage.

Description

technical field [0001] The invention relates to a linear LED lamp circuit, in particular to an intelligent light-controlled linear LED lamp circuit. Background technique [0002] LED lights have the advantages of energy saving and environmental protection, and have been widely used in various occasions. LED lights are mainly divided into two categories: linear LED lights and switching power supply LED lights using switching power supply as the driving power supply. Compared with switching power supply LED lights, linear LED lights are more cost-effective and are currently the most widely used LED lights. [0003] With the in-depth promotion of the concept of intelligent lighting and environmental protection and energy saving, linear LED lights are developing in the direction of intelligence and energy saving. Light-controlled linear LED lights automatically turn on or turn off lights by sensing ambient light, and have been applied in many occasions. The light-controlled li...
