Intelligent sensing systems
Based on the working principle of sensing human body infrared radiation, the unique design and function of LED sensor light has attracted a lot of attention since its launch. LED sensor light utilises the thermal infrared radiation generated by human body, and through the synergistic effect of the human body sensing element in the lamp head part and the Fresnel filter, it realizes the sensing and responding to human body’s activities.
The LED sensor light has three built-in modules, namely the heat-sensing module, the time-delay switch module and the light-sensing module. The heat-sensing module is responsible for detecting the thermal infrared rays of the human body, the time-delay switch module is responsible for controlling the range of time the light is on and off, and the light-sensing module is used to detect the strength of light in the environment.
In a strong light environment, the light sensing module will lock the entire light state, even if someone passes within the range of the LED sensor light, it will not trigger the light on. In the case of low light, the light sensing module will put the LED sensor light on standby and activate the human infrared heat sensing module according to the detected light efficiency value.
When the human infrared heat sensing module senses that someone is active within its range, it will generate an electrical signal, which will trigger the time-delay switching module to switch the light on, and the LED light beads can be energised to light up. The time delay switch module has a set time range, usually within 60 seconds. If the human body continues to move within the sensing range, the LED sensor light will remain on. When the human body leaves, the human body sensing module is unable to detect the infrared rays of the human body, and is unable to send a signal to the time-delay switching module, and the LED sensing light will automatically switch off in about 60 seconds. At this time, each module will enter the standby state, ready for the next work cycle.
Functions
The most intuitive function of this LED sensor light is to intelligently adjust the lighting according to the brightness of the ambient light and the state of human activity. When the light in the environment is strong, the LED sensor light will not light up to save energy. When the light is low, the LED sensor light will enter the standby state, by the time a human body enters the sensing range, the light will turn on automatically. If the human body continues to be active, the light will remain on until it is automatically switched off about 60 seconds after the human body leaves
The launch of LED sensor lights not only provides intelligent lighting solutions, but also effectively reduces energy consumption. It is widely used in public places, corridors, car parks and other areas, which not only improves the lighting effect, but also brings people a more convenient and comfortable living experience. With the continuous progress of science and technology, the application prospect of LED sensor light will be more broad, bringing more convenience and intelligent experience for our life.
