Switch scheme + 5.8G microwave radar - automatic induction control

In response to the national energy conservation and emission reduction policy, "Shenzhen yuejiahong Electronics Co., Ltd." as a semiconductor device agent, not only selects components, but also independently designs radar sensing solutions in line with national standards to provide customers with a full set of solutions for product upgrading and cost optimization;

The scheme has been widely used in indoor public area lighting products such as ceiling lamp, lamp tube, down lamp, three prevention lamp and panel lamp;


Market: indoor public areas, induction lamps and lanterns.

Main features of the scheme:

1. Independent power supply design, more stable scheme and high cost performance;

2. 5.8G radar, with more stable performance, solves the customer complaint problem of 3G radar;

3. Dimming brightness can be DIY (0-100%), which can be selected in a variety of application scenarios;

4. The sensor is hidden in the lamp body, without structural opening, and the appearance design is more beautiful;

Advantages of 5.8G radar:

1. The spectrum is stable, free from 5g base station signal interference, in line with international standards.

2. Independent antenna, strong anti-interference ability;

3. Higher expansibility, remote control and serial port docking.
