LED body sensor lamp principle

May 24, 2017

   LED body sensor lamp is in the traditional separation of the corridor on the basis of the human body to develop the lamp, combined with the corridor lamp body sensor function and LED light source of energy saving, high brightness, environmental protection, long life advantages. With super energy saving, intelligent control, light source and control module integration and other characteristics, completely replace the traditional corridor body sensor lights, corridor sound and light control lights and touch switch lights.

    LED body sensor lamp works can be mainly from the following parts to illustrate:

    LED body sensor lamp is the use of people generated by the thermal infrared radiation. The use of the lamp body part of the human body sensor components, through the circular Fresnel filter, the thermal infrared focus on the surface of the sensor element, resulting in electrical signals, through the signal processing module, delay switch module, light sensor module integrated processing, Detection of the human body under the sensor lights are turned on and off. In the built-in three modules in the thermal sensor module is responsible for detecting the human body hot infrared, delay switch module is responsible for dealing with the long range of light, light sensor module is responsible for detecting the strength of light.

    First, in the daytime or light strong light environment, the light sensor module detects the electrical signal value will be the whole lamp control in the locked state, even if someone through its LED body sensor lamp range will not turn on the lights. In the darker night or night, the light sensor module will be based on the detected light value, will turn on the sensor lights on standby, while the human body infrared thermal sensor module also started. If the human body infrared thermal sensing module senses that the human body is active in its range, it will generate an electrical signal, the signal will cause the delay switch module to turn on the lamp, the LED lamp is energized and the delay switch has a setting within 60 seconds Value, if people continue to be within the scope of induction, LED human body sensor light is always bright, when people leave, the body sensor module does not detect the human body infrared, there is no signal to the delay switch, in about 60 seconds time , LED body sensor lights will automatically shut down. At this time, each module is on standby, waiting for the next work cycle.

    Based on the principle of human body infrared design and development of LED human body sensor lights, the most intuitive in the use of the function is:

(1).White or light when the strong is not bright.

(2). The night when the light is dark, the lamp on standby.

(3). In the standby state, when the human body into the sensor range, LED body sensor lights open.

(4). If people in their range of activities, light is always bright.

(5)When people leave, LED body sensor lights will automatically shut down in 60 seconds.

   So intelligent lighting, to bring the benefits of people to light, people go light off. LED light source has been mature after the application, the LED as a light source, with the human body sensor device, the design of the LED body sensor lights, but also increased the green energy of this powerful feature.
