Several schemes of intelligent energy-saving lighting for underground parking lots
With the development of the city, tens of thousands of underground garages have been created. At present, the lighting source of the garage is basically T8 or T5 straight tube fluorescent lamps, and most of them now have LED fluorescent lamps. Because LED products are energy-saving, environmentally friendly and high in light efficiency, lamps are roughly divided into box lamps and dust-proof lamps. The installation adopts lighting bus method, ceiling method and hanging chain method, etc. The control method basically adopts centralized manual control and is operated by the attendant on duty. Since the underground garage needs 24 hours of lighting, the lamp loss rate is very high, the maintenance workload is large, and the electricity cost is high. In order to solve this series of problems, many professionals have put forward many reference schemes. Let's find out together now!
1. Control and manage public lighting time
To control the lighting time, the common way is to turn on all the lights at different times, 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 and the control is fuzzy, the energy saving effect of this method is limited.
2, reduce the number of lamps
This method is simple and easy to implement, and it can obviously reduce the power consumption of underground garage lighting projects. However, because my country has relevant requirements for the illuminance data of public lighting, if the number of lighting fixtures is excessively reduced, the illuminance of the entire lighting system will not meet the standard. Reducing the number of lamps will reduce the illuminance and increase various safety hazards. Therefore, this method is not suitable for the underground garage lighting renovation program.
3, infrared or microwave detectors used in conjunction with ordinary fluorescent lamps
Infrared detectors are installed on each fluorescent lamp, turn on the lights when people or vehicles are detected, and then turn 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. Ordinary fluorescent lamps are frequently switched on and off, the service life is only 1/3, and the amount of engineering installation is large, the labor cost and equipment investment are large, and this solution is not suitable for underground garage lighting transformation.
4, the use of voice-activated switch and incandescent lamp
Voice-activated switches are generally used in conjunction with incandescent lamps. Incandescent lamp countries have banned the production of incandescent lamps. The disadvantages of low light efficiency, high power consumption, and short life span have been eliminated, so this program is not feasible.
5. Underground garage lighting solutions
Benwei Lighting has developed two products, LED intelligent infrared sensor light and LED intelligent radar sensor light, by virtue of years of LED R&D experience and advanced testing equipment, which completely solved the above-mentioned problems. Due to the perfect combination of (infrared/radar) sensors, intelligent controllers and LED tubes, a unique patented new energy-saving lamp is formed.
The working principle of the LED intelligent sensor light: When there is a car and someone in the garage, the product is fully lit, the power is 16 watts, the luminous flux is more than 1250LM, and its surface brightness is the same as that of the original 36W T8 fluorescent lamp (total power is about 42 watts) The brightness is equivalent, providing sufficient illuminance; when there is no car or no one, the light is in a dim lighting state, and the power is maintained at 3 watts to meet the illuminance required for safety and monitoring. This method perfectly achieves both power saving and lighting.
