What are the sensing methods of the induction lamp? What scenes are induction lights suitable for
Induction lights are very common in daily life. You can see induction lights in homes, office areas, buildings or public places. Because the induction lamp can be started automatically without the use of a switch, it is very convenient to use, so it is very popular. So, do you know what are the sensing methods of the induction lamp? What scenes are sensor lights suitable for? Don't worry, BENWEI will give you a detailed explanation below. Come take a look.
What are the induction methods of the induction lamp
1. Light sensor switch
Light switches are often used in places that require automatic lighting at night, such as front lights of courtyard doors and street lights on urban roads. It is mainly through a photoresistor (its resistance value can be changed according to the light intensity); when the light irradiated on the photoresistor is strong, its resistance value will become lower, the back-end circuit does not work, the lamp will not Bright; when the light irradiated on the photoresistor is weak, its resistance value will become higher, and the back-end circuit will work to make the lamp light up. Its shortcoming is that when it is in a dark environment, the switch will continue to be turned on, the light will always be on, precise control cannot be achieved, and the energy-saving effect is not ideal; it is easily affected by dust or obstacles.
Second, the human touch switch
The human-sensing switch is a further improvement based on the sound control, which can realize the light-on action without sound. It is mainly composed of a pyroelectric sensor, Finier lens and peripheral control circuit. Its working principle is that the pyroelectric sensor can sense the heat radiation released by the human body temperature, and the Finier lens can collect and focus the human body to release infrared rays. When someone appears in the sensing range, the Finier lens focuses the infrared radiation released by the human body heat to the pyroelectric sensor, and then the pyroelectric sensor outputs a control model to the back circuit to realize the light on and off control .
Three, microwave switch
Microwave induction (also called radar induction) is much more perfect than the previous control methods, and is now widely used in underground garages, road lights and other places. It uses a working principle similar to that of a radar to detect moving objects by emitting microwaves, and then generate corresponding switch operations. It has strong anti-radio frequency interference ability, is not affected by temperature, humidity, light, air flow, dust, etc., and can be installed in a non-metallic shell of a certain thickness without being exposed. While achieving the sensing function, it can also maintain the appearance Overall coordination and beauty (microwave induction lamps can be exactly the same as ordinary lamps).
Four, voice control switch
Voice-activated switch is also an earlier automatic control method, usually used in corridors, aisles, corridors and other places. It effectively avoids the influence of dust and obstacles on its use effect. Its working principle is also very simple. It collects sound signals through microphones (microphones commonly known as microphones), and then processes them through the back-end circuit to control the on and off of the switch to turn the lights on and off. Usually we also add a delay circuit on the basis of the sound control switch to realize that the sound sounds and the light is on. After a short period of continuous lighting, the light is automatically turned off.
What scenes are induction lights suitable for
1. Corridor
Traditional induction lights are installed in the corridors. They are generally composed of two parts. One is the human body induction panel switch, and the other is the light source. The light source is mostly incandescent. The two are separated. The line and location are well laid out. The tungsten filament in the incandescent lamp cannot withstand frequent switching, so the broken lamp must be replaced every year, and the manual maintenance cost is too high. The LED human body induction lamp has a built-in light source and human body induction device. You only need to install it and screw it into a general E27 lamp holder to achieve the human body induction lamp. When people come, the light is on, and when people go, the light is off. When it is installed at the corner of the upper and lower stairwell, it can sense the people going up and down. In addition, the LED light source has a long life, low voltage operation, and frequent switching has no effect on it.
2. Balcony
For a long time, most of the lighting fixtures on the balcony are incandescent lamps or ceiling lamps. The balcony is semi-outdoor. When the lights are turned on at night, mosquitoes and flying insects will turn around the lights. I don’t remember from time to time in life. Turn off the lights on the balcony. Install an LED human body induction bulb or a human body induction LED ceiling light in this position. Both of these problems can be solved. LED is a cold light source, does not contain ultraviolet rays, does not attract mosquitoes, and intelligently senses the human body. On, the light is off after the person leaves, which saves electricity and is convenient.
3. Property corridor
There are dozens of households in one building. It is also very suitable to install LED human body sensor lights in the public corridors of each floor. In 1 minute, the owner has enough time to open his door and enter the house. Compared with the light bulb that is always on at this location, this saves much electricity. But to install such lamps in this location, the real estate developer or the property can make a decision.
Four, utility room
The utility room is too messy. The room is small and dark. You can't see where the switch is when you go in. When you come out, you have to put down the things in your hand and turn off the lights. If you are so troublesome, install LED human body induction lights to solve this problem. Well, install it on the roof of the room. When you open the door and enter, the light will automatically turn on. The light is always on when you are looking for items. Take what you are looking for and go directly. You don’t have to be careful that no one turns off the light. , After 60 seconds, you look back to see that it has been automatically turned off.
The above is a brief introduction of what are the sensing methods of the induction lamp and which scenes the induction lamp is suitable for. I hope it will be helpful to everyone.
