A lighting control method and lighting fixture based on human body induction

Abstract

The present invention provides a lighting control method based on human body induction and a lighting fixture. The lighting fixture includes: a housing, a power supply module packaged in the housing, a microcontroller, and a light source module communicated with the microcontroller. , a driving module and at least one first sensor; wherein, the driving module is used to generate a driving signal under the control of the microcontroller and transmit it to the light source module; the light source module is used to drive based on the transmission of the driving module The signal periodically generates a first outgoing light with a first preset frequency; the first sensor is configured to receive a first reflected light after the first outgoing light is reflected in the current environment, and generate a first electrical signal based on the first reflected light and then transmitted to the microcontroller; the microcontroller is also used to control the lighting state of the light source module according to the first electrical signal. The overall structure of the lighting fixture provided by the invention is simple, and the cost can be reduced while intelligently providing lighting.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a lighting control method based on human body induction and a lighting fixture. Background technique [0002] With the continuous development of science and technology, in the lighting field, the switch of the lamp is often controlled by the human body induction sensor. When a person is detected in the space, the lamp is turned on for lighting; otherwise, the lamp is turned off. As a basic and general-purpose sensor, the human body induction sensor is mainly used to detect whether there is a person in a certain space. Through the human body induction sensor, the lamp can be turned off when lighting is not needed, thereby saving energy and electricity costs. [0003] There are many main implementation technologies of commonly used human body induction sensors: pyroelectric sensors, thermopile sensors, microwave sensors, cameras, etc. These sensors have their own advantages, but...

AI Technical Summary

Problems solved by technology

But this will bring another problem: if people enter the room and then leave immediately, because the human body sensor is triggered, it will take a long time to turn off the lights, which will cause energy waste

[0004] In addition, although the camera can identify the human body, there is a possibility of privacy leakage; the thermopile can detect the existence of the human body, but the price is relatively high, and it is not easy to popularize
