Which scenarios are the induction lights suitable for?
Induction lights are very common in daily life, and can be seen in homes, office areas, buildings or public places. Because the sensor light can be automatically activated without using a switch, it is very convenient to use, so it is very popular. So, do you know what the sensing methods of the sensor light are? What scenarios are the induction lights suitable for? Come check it out.
What are the sensing methods of the sensor light?
1. Human switch
The human-sensing switch is further improved on the basis of voice control, which can realize the light-on action without any sound. It is mainly composed of a pyroelectric sensor Garfiner lens and a peripheral control circuit. Its working principle is that the pyroelectric sensor can sense the thermal radiation released by the human body temperature, and the Fresnel lens can collect and focus the infrared radiation released by the human body. When someone appears in the sensing range, the Fresnel lens focuses the infrared radiation released by the body heat onto the pyroelectric sensor, and then the pyroelectric sensor outputs a control model to the rear circuit to realize the control of the light on and off. .
Second, the voice switch
Voice-activated switch is also an early 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. The sound signal is collected through the microphone head (the microphone of the microphone is commonly known as the microphone head), and then processed by the back-end circuit to control the on and off of the switch to realize the on and off of the light. Usually, we also add a delay circuit on the basis of the voice-activated switch, so that the sound will sound, the light will be on, and after a short period of time, the light will automatically turn off.
3. Light sensor switch
Light sensor switches are often used in places that require automatic lighting at night, such as courtyard door headlights, street lights on urban roads, etc. It mainly passes through a photoresistor (its resistance value can be changed according to the light intensity); when the light shining 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 shining on the photoresistor is weak, its resistance value will become higher, and the back-end circuit will work to light up the light. Its disadvantage is that when it is in a dark environment, the switch will continue to be turned on, and the light will always be on, which cannot achieve precise control, and the energy saving effect is not ideal; it is easily affected by dust or obstacles.
4. Microwave switch
Microwave induction (also known as radar induction) is much more perfect than the previous control methods, and is now widely used in underground garages, road lighting and other places. It adopts a working principle similar to radar, detects moving objects by emitting microwaves, and then generates corresponding switching operations. It has strong resistance to radio frequency interference, is not affected by temperature, humidity, light, airflow, dust, etc., and can be installed in a non-metallic shell of a certain thickness without being exposed. While realizing the induction function, it can also maintain the appearance. Overall coordination and aesthetics (microwave induction lamps can be made exactly the same as ordinary lamps).
Which scenarios are the induction lights suitable for?
1. Corridor
There are many traditional induction lamps installed in the corridors, which are generally composed of two parts, one is the human body induction panel switch, and the other is the light source. Most of the light sources are incandescent lamps, and the two are separated. Lines and locations are laid out. The tungsten filament in the incandescent lamp cannot withstand frequent switching, so the broken lamp must be replaced every year, and the labor maintenance cost is too high. The LED human body induction light has a built-in light source and a human body induction device. It only needs to be screwed into the general E27 lamp socket to achieve the human body induction light. The light is on when people come and the light is off when people leave. When installed, it is placed at the corner of the upper and lower stairwells, and people who go upstairs and downstairs can be sensed. In addition, the LED light source has a long life, low voltage operation, and frequent switching has no effect on it.
2.The 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 on each floor. Whenever the owner goes home and walks out of the elevator, the LED sensor lights will turn on. In 1 minute, the owner has enough time to open the door of his house and enter the house. Compared with the light bulb that is always on at this position, this saves much electricity. But to install such lamps in this location, it is up to the real estate developer or property to make a decision.
3. Balcony
For a long time, most of the lighting fixtures on the balcony are incandescent lamps or ceiling lighting lamps. The balcony is semi-outdoor. When the lights are turned on at night, mosquitoes and flying insects will circle around the lights, and I don’t remember them from time to time in life. Turn off the balcony lights. Install LED human body induction bulbs or human body induction LED ceiling lights in this position, both problems can be solved. LED is a cold light source, does not contain ultraviolet rays, and will not attract mosquitoes. On, the light goes off when people leave, saving power and convenience.
4.the utility room
The utility room is a messy place. 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 to turn off the light. If it is so troublesome, you can install LED human body induction lights to solve it. Let's install it on the roof of the room. When the door is opened, the light will automatically turn on. When looking for items, the light is always on. Just take what you are looking for and go directly. , after 60 seconds you look back to see that it has automatically turned off.
The above is the induction mode of the induction lamp and the whole content of which scene the induction lamp is suitable for is briefly introduced here. I hope it will be helpful to everyone. If you want to know more about lamps and lanterns, please contact us quickly.
