With the improvement of people's living standards, cars have become standard equipment for every household. This has also led to the construction of a large number of underground parking garages. With the increase of underground parking garages, the use of electricity has also increased. Solving this electricity problem has become an urgent matter, and this situation exists in shopping malls, communities, and real estate in various places; At present, there are three kinds of garage LED sensor lights on the market: sound and light control sensor, infrared human body pir sensor, radar sensor LED fluorescent lamp, Among these three types of lights, microwave radar sensor LED fluorescent lights daylight is the most suitable for use in underground parking garages. Why? Let's take a look together!
The microwave radar sensor LED fluorescent lights is not only has high sensitivity, but also covers a long area, has no dead angle of 360°, can penetrate non-metallic objects, and is not affected by temperature and environment. Even if the underground garage temperature is above 37℃, the sensing distance will not be shortened at all. The reaction speed is fast, the sensor is built-in, just like ordinary lamps, and the probability of false triggering is small. It can be triggered when the car speed reaches 20-25km/h in the parking lot and the car is 8-10 meters away from the lamp. Change to 100% brightness.
These just happen to be the defects of sound and light control and infrared human body induction lamps.
1. Human body pir sensor LED fluorescent lamp: The sensing distance is 2-5 meters. The working principle is to detect the change of infrared energy. Affected by the temperature of 37℃, the temperature of the underground garage in summer and autumn is generally above 35℃, which causes its sensing distance to be long in winter and short in summer. . The infrared sensor needs to be exposed to affect the appearance.
2. Sound and light control induction LED fluorescent lamp: The sensing distance is related to the sound decibel. When the scene environment is not noisy, the light will appear for a long time. When the sound is too small, it may not be triggered. Use the sensor probe for a long time It will be blocked by dust and affect the sensing function. Affected by the outside world.
Most of the parking garages now use radar-sensing led fluorescent lights, which will automatically turn off after a 15-20 second delay after the car leaves. This achieves the effect of energy saving, which can also extend the service life of electrical appliances, which is safe and convenient! The composition of microwave radar sensor LED fluorescent lights is divided into led light source, driving power supply, induction small plate, heat dissipation aluminum material, resulting in low power consumption, long life, high brightness and environmental protection; in addition to being used in underground parking lots, it can also be used in: warehouses, Libraries, corridors and other public places that require long-term lighting.
