A light source driving device

Abstract

The invention discloses a light source driving device, the driving device includes a sensing unit and a processing unit, the sensing unit at least includes a microwave sensing module; the sensing unit is at least used for: according to a certain microwave sensing cycle , based on the sensing of microwaves, sensing whether there is human activity within its range of action, and periodically outputting a sensing signal to the processing unit; the processing unit is used for: based on the processing of the sensing signal , so that the driving device can adaptively control the on and off of the light source and the change of the brightness of the light source. Based on this, the present invention realizes a dynamic intelligent light source driving device that does not need to be turned on and off by the user and is based on environmental state sensing.

Description

technical field [0001] The present invention relates to the lighting field, and more specifically, to a light source driving device. Background technique [0002] On the one hand, with regard to the controlled on and off of the light source, and the brightness adjustment, the existing technology can only be realized after adding an additional intelligent control system on the basis of the existing switch and its circuit. Except for fluorescent lamps and LED lamps, even the most Simple incandescent lamps can also be realized by adding a thyristor dimmer, and its intelligence is limited. [0003] On the other hand, when driving an LED light source module, whether it is a digitally controlled or analog-controlled LED drive power supply, regardless of the specific installation situation of the LED light source module, the corresponding environmental requirements will always change. Even if the control system is installed, someone still needs to monitor and manage in the monitor...

AI Technical Summary

Problems solved by technology

That is to say, the existing technology cannot automatically and switch-free control the light source due to the flow of people to achieve the purpose of saving energy and prolonging the service life.

[0004] There are many microwave and infrared sensor lights on the market, but the existing technology triggers the lights by simply judging whether there is human activity in the environment, and cannot dynamically adjust the brightness accordingly. In addition, the existing technology uses a fixed-time timing circuit to turn off the lights, so for many years this kind of light source can only be used in aisles, stairwells and other environments where there are basically no activities, and does not involve indoor and other environments where people stay for a long time. The need for intelligent control of switches
