The lighting of the underground parking lot is due to long-term continuous lighting. If it is illuminated by ordinary LED fluorescent lamps, first, the lamp bead is affected by high temperature for a long time, and the attenuation is fast. Second, when there is no one in the middle of the night, power is wasted, so In order to solve the lighting of the underground parking lot, it is necessary to greatly extend the life of the LED fluorescent lamp, and at the same time to save energy, it is necessary to consider the environment of the parking lot and be intelligent. This article lists three parking garage LED lighting solutions that provide ideas for parking garage lighting.
Intelligent voice control solution
1. Adopt self-developed CPU control, intelligently detect the surrounding environment and automatically adjust the working status;
2. Ultra-low lighting power consumption at rest, generally 2-2.5W, and adjustable according to the environment;
3. When the car enters, it automatically senses full load operation, 10-18W (0.6 or 1.2 m lamps)
4. Full working time: 2 seconds - 60 seconds according to the environment;
5. Motion sensing sensitivity: 45dB;
6. Daily average power consumption: 4.8 watts; (8 hours of work, 16 hours of static, 10W of full load)
7. Suitable for underground lighting, shopping malls, stairs and other long lighting places.
8. Wide voltage input for global use.
The voice control scheme is characterized by detecting the surrounding sound environment. If the surrounding environment is too sloppy, it is easy to keep lighting. On the contrary, if the surroundings are too quiet, it may not be triggered, so the sensitivity setting is very important. For this problem, sensitivity and The time-adjustable solution allows the user to set the sensing sensitivity according to the surrounding environment. However, some users are unfamiliar, but the adjustable potentiometer is broken. This is especially important.
Intelligent human body sensing solution
1. Adopt self-developed CPU control to intelligently detect the surrounding environment and automatically adjust the working status;
2. Ultra-low lighting power consumption at rest, generally 2-2.5W, and adjustable according to the environment;
3. When the human body enters, it automatically senses full load operation, 10-18W (0.6 or 1.2 meter lamps)
4. Full working time: 2 seconds - 60 seconds according to the environment;
5. Sensing sensitivity: 1-2.5 meters;
6. Daily average power consumption: 4.8 watts; (8 hours of work, 16 hours of static, 10W of full load)
7. Suitable for underground lighting, shopping malls, stairs and other long lighting places.
8. Wide voltage input for global use.
The human body sensing scheme is characterized by detecting pyroelectric infrared rays emitted by the human body, and collecting the energy of the human body infrared rays by using a Fresnel lens. An obese person emits more infrared energy, whereas a thin person emits less infrared energy. Therefore, obese people and small people have different sensitivity, and the general sensing distance is 2-4 meters, and it is suitable for people. Since pyroelectric infrared sensing is to detect infrared rays of the human body, the body temperature of the human body is generally 37.5 degrees, and the temperature near the LED fluorescent lamp head is generally about 40-45 ($0.8415) degrees, so the interference of the temperature and light of the fluorescent lamp is relatively large. In response to this problem, a light-shielded and insulated lamp holder can be specially developed to effectively solve the problem of light interference and thermal interference. It is generally recommended that the human body-sensing fluorescent lamp is more suitable for the corridor. If it is applied to the parking lot, it is necessary to carefully confirm the relationship between the surrounding environment and the person. On the first use, the CPU requires a one-cycle reset time, and the second start of the trigger is accurate.
Intelligent radar sensing solution
1. Adopting the Doppler principle, independently researching and developing the radar transmitting and receiving circuit, intelligently detecting the surrounding environment and automatically adjusting the working state;
2. Ultra-low lighting power consumption at rest, generally 2-2.5W, and adjustable according to the environment;
3. When an object enters the radar area, it automatically senses full load operation, 10-18W (0.6 or 1.2 meter lamp)
4. Full working time: 2 seconds - 60 seconds according to the environment;
5. Sensing sensitivity: 3-5 meters;
6. Daily average power consumption: 4.8 watts; (8 hours of work, 16 hours of static, 10W of full load)
7. Suitable for underground lighting, shopping malls, stairs and other long lighting places.
8. Wide voltage input for global use.
The intelligent radar sensing scheme uses the Doppler principle to transmit a microwave radar signal of about 5.8 GHz. When a moving object enters the electromagnetic field of the radar, it can feedback the signal to the receiving circuit, thereby triggering the changing of the working state of the circuit. The general sensing distance can be 5-9 meters, as long as the object moves to trigger. Although the object is within its trigger range, it will not be triggered if it does not move. Radar induction can penetrate non-metallic objects such as plasterboard, wood, etc., and is especially suitable for concealed installation. If a metal object blocks the emitting surface, it will greatly reduce its sensitivity, so pay special attention to it. Radar induction is less affected by interference and has higher sensitivity, which is especially suitable for lighting solutions in underground parking lots.
