Infrared human body induction lamp uses the thermal infrared emitted by the human body to detect and generate electrical signals by thermal induction elements. Through the induction device, the lamp can be controlled to turn on and off. It has the characteristics of light on when people come and light off when people go. It is very power-saving, trouble-saving and intelligent.

The traditional infrared human body induction lamp is composed of an induction switch panel and a light source, which are in a separate state. The induction switch panel is installed on the wall, similar to the socket. Most of the load light sources are incandescent lamps. The installation position must be planned before installing the line. The two cannot be too close or too far away. For the location in the downlight or in a small room, the flexibility is relatively poor. In the process of use, incandescent lamps are relatively power consuming lamps. Although they have human body sensing devices, which can light up when people come and light out when people walk, and also save electricity, incandescent lamps are easy to burn out during frequent opening and closing, and the cost of manual maintenance is high, so they should be replaced frequently.

Led human body induction lamp is a new type of intelligent lamp designed and produced with LED lamp beads as light source. It is by far the most energy-saving, intelligent and convenient infrared induction lamp. LED lamp is a solid-state light source, with low voltage operation, long service life and high luminous efficiency. Led human body induction lamp combines the light source with infrared induction device. It can be used normally only by screwing the lamp on the lamp holder interface with an ordinary lamp holder.

Many manufacturers of LED human body induction lamps are also developing and producing. In the author’s investigation, it is found that most of them can only be used as reminder signs, night lights, toys and gifts. The LED light source is less than 20 light beads, and some have only a few. The brightness is far from meeting the lighting requirements. If they are installed in staircases, balconies, warehouses and other locations, they are not competent to undertake basic lighting tasks.

To sum up, compared with traditional human body induction lamps, led human body induction lamps have several obvious advantages. First, the integration of light source and induction device. 2、 Super power saving, the light source power is only one sixth of that of incandescent lamps, but the brightness is equivalent to that of incandescent lamps. 3、 The super long service life can reach 30000-50000 hours, eliminating many labor costs of replacement and maintenance. 4、 The installation is flexible. Only a common lamp holder with 220V voltage can be connected, which is convenient for installation. 5、 It is widely used and can undertake basic lighting tasks. It is used in staircases, balconies, warehouses and underground parking garages.
