Working principle and function of LED intelligent induction night light scheme development
This paper introduces the working principle of the scheme development of electrothermal foot warming treasure; It is widely used in corridors, balconies, kitchens, toilets, warehouses, elevator entrances, children's rooms, hotel aisles, utility rooms and other new generation green, energy-saving and intelligent lighting local fixtures that need to be opened and closed automatically.
principle
The product adopts the functional program design of MCU (single chip microcomputer main control chip). Infrared detection method has the characteristics of intelligent induction and automatic switching.
Led human body induction lamp adopts active infrared technology, with built-in human body infrared sensor module, light effect sensor module and delay switch module. Integrated codec transmission, decoding reception, control output, consumer electronic chip, large load capacity and strong anti-interference ability.
LED intelligent induction night light
Led human body induction lamp is developed on the basis of traditional separated corridor human body induction lamp. It combines the human body induction function of corridor lamp and the advantages of LED light source. It has the advantages of high brightness, environmental protection and long service life. It has the characteristics of super energy saving, intelligent control, integration of light source and control module, and completely replaces the traditional corridor human body induction lamp, corridor acousto-optic control lamp and touch switch lamp.
function
1. Not bright in white or strong light;
2. When the light is dim at night, the bulb is in standby mode;
3. In standby mode, when the human body enters the sensing range, the LED human body sensing light will light up;
4. If someone moves within its range, the indicator will always be on;
5. When a person leaves, the LED human body sensing light will automatically turn off within 60 seconds.
LED intelligent induction night light
advantage
The advantage of such intelligent lights is that when people come, the lights are on, and when people go, the lights are off. With the mature application of LED light source, led human body induction lamp designed with LED as light source, combined with human body induction device, increases the powerful function of green energy saving. The LED human body sensing function does not use the red control source of light and human heat release. It automatically controls the light, avoids the cumbersome manual switching of lights, and has the ability to automatically delay the extinction. It is more energy-saving, and has no mechanical contact, no spark and long service life. It is widely used in public places such as stairs, corridors and toilets of various buildings. The built-in automatic human body sensor uses infrared equipment to accurately capture the low-frequency signal of the human body, and automatically turns on the light to realize the person's arrival at the light. When the light is turned on, it will be automatically delayed, when the light is off, and when the person will go. No adjustment required!
