Selection of LED tube for underground garage lighting transformation
The common way to control the lighting time is to turn on all the lights in time intervals, that is, turn on all the lights during the day and the first half of the night, and turn off half of the lights in the second half of the night. Because the time is too short, the energy saving effect of this method is also very limited. Not suitable for underground garage lighting renovation.
Infrared or microwave detectors are used in conjunction with fluorescent lamps. Infrared or wave detectors are installed on each fluorescent lamp. When a person or vehicle is detected, the light is turned on, and then it is turned off after a delay. When the fluorescent lamp is turned on, there is a start-up delay of 1-1.5 seconds, so the light is always behind the vehicle. At the same time, ordinary fluorescent lamps do not have dimming control and have the effect of spotlights, which can make people feel scared. Not suitable for underground garage lighting renovation.
When combined with a voice-activated switch for lighting, the start-up delay of fluorescent lamps is not suitable for frequent switching, so the common solution is to use incandescent lamps instead of fluorescent lamps. However, the luminous efficiency and lifespan of incandescent lamps are 5-6 times different from fluorescent lamps, and incandescent lamps are not suitable for frequent switching. The lighting control in underground garages using voice-activated switches is often in a disordered state, and a large area can be illuminated by pressing the horn. The energy-saving effect is not good, and frequent flashing makes people dizzy, not suitable for underground garage lighting renovation. Infrared sensor + LED lighting = dual-brightness intelligent LED tube (underground garage lighting renovation expert) was born.
