LED Human Sensing Light Working Principle

LED human body sensor light is developed on the basis of the traditional separated corridor human body sensor light, which combines the human body sensing function of the corridor light and the advantages of energy saving, high brightness, environmental protection and long life of LED light source. It has the characteristics of super energy saving, intelligent control, integration of light source and control module, etc., and completely replaces the traditional corridor human body sensor lamp, corridor sound and light control lamp and touch switch lamp.

The working principle of LED human body sensor light can be explained from the following parts:

LED human body sensor lights use the thermal infrared radiation generated by people. Using the human body sensing element of the lamp head part, through the circular Fresnel filter, the thermal infrared rays are focused on the surface of the sensing element to generate electrical signals, and the signal processing module, delay switch module, and optical sensing module are comprehensively processed to analyze whether the human body sensing lamp is turned on and off under the detection value. Among the three built-in modules, the thermal induction module is responsible for detecting the thermal infrared rays of the human body, the delay switch module is responsible for processing the lighting time range, and the light sensing module is responsible for detecting the intensity of the light.

First of all, in the daytime or in a strong light environment, the electrical signal value detected by the light sensor module will control the whole lamp in a locked state, even if someone passes through the range of its LED body sensor light, the light will not be turned on. In low light or at night, the light sensor module will turn on the sensor light in standby state according to the detected light efficiency value, and the human infrared heat sensor module will also be activated. If the human body infrared thermal induction module senses that there is a human body in its range of activities, it will produce an electrical signal, the signal prompts the delay switch module to turn on the lamp, the LED lamp beads are energized and the light is on, the delay switch has a setting value within 60 seconds, if the person continues to be within the sensing range, the LED human body induction light is always on, when the person leaves, the human body induction module does not detect the human body infrared, and there is no signal to the delay switch, in about 60 seconds, the LED human body induction light will be automatically turned off.

At this point, the individual modules are on standby, waiting for the next work cycle.

Based on the working principle of human body infrared, the LED human body sensor lamp developed and designed, the most intuitive function in use is:

1. It is not bright when it is white or the light is strong.

2. When the light is dim at night, the lamps are on standby.

3. In the standby state, when the human body enters the range of induction, the LED human body induction light is turned on.

Fourth, if a person moves within his range, the light is always on.

5. When the person leaves, the LED body sensor light will automatically turn off within 60 seconds.

The benefit of such intelligent lamps and lanterns to people is that the lights are on when people come and the lights are off when people leave. Following the mature application of LED light source, LED is used as a light source, and the LED human body sensor lamp is designed with the human body sensing device, which adds the powerful feature of green energy saving.

LED human body sensor lamp is the use of the principle of infrared thermal radiation of the human body, using MCU (microcomputer control unit) circuit design, active infrared detection mode, with intelligent induction, automatic switch and other characteristics, widely used in corridors, balconies, kitchens, toilets, warehouses, elevators, children's rooms, hotel walkways, utility rooms and other places that need to be automatically opened and closed, the latest generation of green, energy-saving, intelligent lighting fixtures.

The LED human body sensor light adopts active infrared technology, with built-in human body infrared sensing module, light effect sensing module, and delay switch module. The integrated codec mode transmits, decodes and receives, controls the output, adopts industrial zone-level chips, has large load capacity and strong anti-interference ability.

The LED human body sensor light adopts the domestic and international E27 spiral interface, AC 180-240V voltage input, as long as it is screwed into the spiral lamp holder, it can work when the power is turned on, and there is no need to switch it frequently.

The LED human body sensor lamp uses light and human body pyrothermal infrared as the control source to automatically control the lighting on and off, avoiding the cumbersome manual switching on and off of the lamp, and at the same time has the ability to automatically delay the extinguishment, which is more energy-saving, and has no mechanical contact, no spark, and long life. It is widely used in public places such as staircases, aisles, and toilets in various buildings. The internal automatic human body sensor adopts infrared pyrolysis device, which accurately captures the low-frequency signal of the human body and automatically turns on the light to realize the person to the light, the automatic delay when it is on, and the light is off when the person walks, without the need to install a switch, which is easy to use and energy-saving at the same time.

Functionally speaking, the sensor night light does not rely on mobile phones, and it has a wide range of applications. The basic operation is as follows:

To use the night light, press the on/off key to turn on the night light.

OFF key: Turn off the night light.

on: Always-on mode, the night light is always on.

Auto button: Sensing mode, when human activity is detected in a dark environment, the night light will automatically turn on and turn off automatically after 15 seconds.

In addition to the movable and fixed types of sensor night lights, it is generally a strong sticker on the back that can be glued to the wall. Or there is a hook on the back that can be hung on an object.

The correct use of the induction night light: the infrared human body sensing range is 5-7 meters in front, 120 degrees horizontally, 2-3 meters on the side, with a light-sensitive sensor, it will be automatically turned on under dark light conditions, and it will be activated when people are close to this range.

Readers and friends may find that there are no manual light switches in some places, but the lights can be turned on in other ways, which may be the installation of voice-activated switches, or LED human body sensor lights. So, you may be wondering what kind of lights look like through human body sensing? What are the characteristics of LED human body sensor lights?

How is the LED human body sensor light wired?

What is LED Occupancy Sensor Light.

LED human body sensor lamp is a new generation of intelligent lighting fixtures that rely on sensing the infrared heat radiation of the human body, detecting the state of the light environment, and turning on and off the lamp through the built-in delay switch. LED infrared sensor light has a wide range of applications, underground garages, factories, warehouses, corridors, elevators, entrances, balconies and other areas that need to automatically turn on and off the lighting are very applicable.

Features of LED Human Sensing Light:

LED human body sensor lamp set LED light source, infrared induction and light sensitive control system, lamps in one, in the evening or the light ruler slow line is dim and someone in the induction range of activities automatically turned on, when the human body leaves or stops the activity after the delay extinguished, to achieve "people come to the lights on, people go lights out", energy saving and environmental protection. There is no need for manual switching in this process, which is noiseless and more environmentally friendly. LED human body sensor light is highly efficient and energy-saving, with long life and stable performance.

How to wire the LED human body sensor light.

The installation method of the existing building renovation: replace the lamps, short the original switch line, or put them in the open state, and the lamps can be connected to electricity. The installation method of the new building: there is no need to arrange switches and pipelines on the wall, and the lamps can be directly connected to electricity.

The wiring of the LED occupancy sensor light is one of the parts of the correct installation of the LED occupancy light, and the correct installation can ensure the effective use in the future. In fact, the emergence of LED human body sensing lights has once again changed people's lifestyles, because of its many advantages, in addition to traditional lamps and voice-activated light switches, people have a good choice.

With the progress of science and technology, lamps and lanterns are becoming more and more intelligent, for example, walking in the dark corridor, is it inevitable to feel a little scared, temporarily find the switch is also more troublesome, the emergence of LED human body sensing lights, you can achieve "people come to the lights on, people go lights out". So, what are the benefits of LED human body sensor lights? What problems should be paid attention to when using human body sensor LED lights?

Let's learn together.

First, the advantages of LED human body sensor lights.

1. The early model school adopts an intelligent lighting tool with integrated design, and selects LED tubes, infrared induction and light-sensitive control systems as a whole, which perfectly realizes the "lights are on when people come and lights are off when people go".

2. The response of the LED human body sensor lamp is fast and sensitive, and it is very energy-saving, it is a new generation of energy-saving and environmental protection products, it is only at night or in a darkly lit area, when someone appears in the sensing area, the infrared sensor module will start and detect the signal, and the signal triggers the delay switch module to turn on the LED infrared sensor light. If the human body continues to move within its range, the LED body sensor light will be always on. When the person leaves the area, the delay is extinguished, and there is no infrared Luhe induction signal, and the delay switch automatically turns off the LED infrared induction light within the time set value.

Each module returns to standby and waits for the next cycle. In this process, there is no need to manually press the switch, no noise will be emitted, and it is more environmentally friendly.

3. The human body sensor LED light is highly efficient and energy-saving, and the performance is stable, so the service life is longer. The 4W or so body-sensing LED light is comparable to the 40W energy-saving bulb.

2. Precautions for LED human body sensor lights.

1. Try to choose a reliable sensor lamp brand when purchasing, if it is an infrared sensor lamp, try to choose a hemispherical probe, this kind of probe sensor lamp has a wider and more reliable detection area for human code search. In order to make the lamps more beautiful, many manufacturers do not use hemispherical probe design, so the sensing area is narrow.

2. If it is only used indoors, there is no need to purchase microwave sensor lamps for the pursuit of sensing distance. If the sensing distance is long, resulting in a larger sensing area, the light is likely to turn on when you don't need it, causing false touch sensing. Therefore, when we buy, we should choose the appropriate type of sensor lamp according to the occasion.

3. If it is an outdoor LED human body induction lamp, it is necessary to consider arranging the circuit in advance, and special attention must be paid to waterproof problems during installation to avoid leaving potential safety hazards.
