Lamp light control system capable of automatically adjusting brightness

Abstract

The invention discloses a lamp light control system capable of automatically adjusting brightness. The lamp light control system comprises a controller, a photoelectric sensor, a lamp bulb, a power source, a first variable resistor and a compensation unit; the input ends of the controller are connected with the power source and the photoelectric sensor; the output end of the controller is connected with the first variable resistor; and the compensation unit is connected between the controller and the lamp bulb. According to the lamp light control system of the present invention, the first variable resistor is controlled by the controller, so that lamp light can be adjusted to a comfortable brightness; when the voltage of the power source changes, the brightness of the lamp bulb changes, and the photoelectric sensor senses the change of light intensity, converts the light intensity at this moment into current signals, transmits the current signals to the controller; and the controller re-adjusts the first variable resistor, so that the brightness of the lamp bulb recovers. A traditional lamp light system changes with the change of a voltage, so the lamp light will be too bright or too dark due to an excessively high voltage or an excessively low voltage respectively, and as a result, the people's eyes would be hurt, and the eyesight of the people can be affected, while, with thelamp light control system of the invention adopted, the problems of the traditional lamp light system can be solved.

Description

Technical field [0001] The invention relates to a lighting system, in particular to a lighting control system capable of automatically adjusting brightness. Background technique [0002] The light bulb is made according to the principle of the thermal effect of electric current. It refers to a lighting source that emits light and generates heat through electrical energy. It was invented by Henry Goebbels. "Lighting appliances" are produced with the continuous development of human civilization. The most common function of light bulbs is lighting. With the development of society, the use of light bulbs has also undergone different changes. Initially, it may be to provide convenience for production and life, but with the progress of society, there have been obvious changes in the use of light bulbs, and there has been a "car, beautification" Functional lamps for different purposes such as environment and decoration. [0003] Since the development of society, people’s requirements fo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a lighting control system that can automatically adjust the brightness to solve the problem that the traditional lighting system will change due to the change of the voltage. If the voltage is too high or too low, the light will be turned off too bright or too dark, thus hurting people's eyes. , problems affecting vision
