Garage/corridor/stair millimeter wave radar sensor LED light intelligent lighting sensing technology, energy saving must start from on-demand lighting, especially in public buildings such as underground garages, corridors, and stairs. The effective lighting time in these places is very different from the actual lighting time. Smart LED lights equipped with radar microwave technology can play the role of lighting people. The dim dimming of people's walking lights can not only provide lighting, but also achieve a good energy-saving effect.
The conference on the application and promotion of high-efficiency lighting and energy-saving technology in public buildings hosted by the Beijing Energy Conservation and Environmental Protection Center, developed by the National Development and Reform Commission and the United Nations Development Program, will gradually phase out incandescent lamps and accelerate the promotion of the energy-saving lamp project sub-project.
It is reported that in addition to the advantages of low energy consumption, no pollution, no mercury, no screen flicker, and long service life, the application of millimeter-wave radar sensors to LEDs has strong controllability, which is different from traditional light sources. Therefore, it can be closely combined with the environmental protection concept of on-demand lighting, and has excellent energy-saving effects in the promotion and application of public building areas, and has strong competitiveness.
The installation of the millimeter-wave radar sensor LED bulb is also particularly convenient. It adopts the existing interface mode, namely screw and socket mode (E27). In order to meet people's usage habits, it imitates the shape of an incandescent light bulb. Based on the principle of LED unidirectional light emission, the light distribution curve of LED bulbs is basically the same as that of point light sources of incandescent lamps. Based on the luminous characteristics of LEDs, the structure of radar-sensing LED bulbs is basically divided into light sources, drive circuits, sensing modules and heat sinks, creating LED bulbs with low energy consumption, long life, high luminous efficiency, and environmental protection.
In addition to the characteristics of the light on when people come and the light on when people leave, the millimeter-wave radar sensor LED bulb also has the following functions:
1. Using the Doppler effect principle, independently develop the plane antenna transmitting and receiving circuit, intelligently detect the surrounding electromagnetic environment, and automatically adjust the working state;
2. When a moving object enters, it automatically senses full load;
3. The ability to adapt to the environment: indoor and outdoor -40 ℃ -65 ℃, humidity ≤ 65% can operate normally and safely.
4. Delay working time: adjust 5-30 seconds according to the environment;
5. Induction sensitivity: 0.5-8 meters.
6. Daily power consumption: 1W;
7. More stable and reliable than infrared induction.
8. Energy saving, environmental protection, low energy consumption: The characteristics of environmental protection, energy saving, ultra energy saving, ultra low cost, low power consumption and long life have advantages in saving maintenance costs.
9. Light control function: The light can be controlled not to light up during the day, and the induction light can be started at night.
