The China Academy of Building Research is the largest comprehensive research and development institution in the national construction industry. It is a quality supervision and inspection institution for construction projects with a fair status authorized by the state. The newly-built scientific research building project is a 20-story fine-decorated scientific research building with a 4-storey basement with a building area of ​​65,000 m2 and an investment of 150 million. The underground parking lot lighting fixtures have been determined to adopt Warwick Capita patents. The total number of products and lamps is 499ç›.
The products adopted this time are organically combined with passive infrared mobile sensors, intelligent controllers and LED light sources to form a unique new energy-saving lamps. When someone has a car in the parking lot, the product is highlighted, with a power of 18 watts. The surface brightness is comparable to the brightness of the original T8 fluorescent lamp (total power of about 48 watts). The site has sufficient illumination; When there is no car, the light is in a dormant state, the power is kept at 2 watts, and the minimum brightness required for safety is maintained on site. In this way, the maximum power saving effect is achieved. Thanks to the integration of sensors and intelligent controllers, the concept of “on-demand lighting†is truly realized; after the lamps are triggered for high brightness, there is a certain time delay, so when the vehicles frequently enter and exit, the lamps exhibit continuous high brightness. , to avoid the uncomfortable feeling caused by frequent changes in brightness.
   We will use the underground parking lot of 500 lights as a comparison of energy saving. At present, most of the underground parking lots use more than 90% of the ordinary T8 fluorescent lamps. The power of the lamp is 36 watts, assuming its 4W. Ballast, the power of a single lamp is equivalent to 40 watts. It is 24 hours of lighting, multiplied by 365 days of it,
Then fluorescent tube:
40*24*365*500*1/1000=175200 yuan (electricity fee is about 1 yuan / kWh)
Annual maintenance fee: 500*2*20=20,000 yuan (since the life of this fluorescent lamp is relatively short, it is about 2,000 to 3,000 hours, so if it is down, it needs to be replaced at least twice a year, and the cost is 20)
Total cost of fluorescent lamps: 175200+20000=195200
Warwick Captain's LED Smart Light:
(12*8+2*16)*365*500/1000=23360 yuan (electricity fee is about 1 yuan / kWh)
Annual maintenance fee: 0 yuan (since it has a service life of 5 years, it has no maintenance cost)
Warwick Kaide smart light total cost: 23360 yuan
 In this case, the cost savings of Warwick Captain's lamps for one year is 171,840 yuan.
Hua Wei Kaide lighting applications in the Construction Research Institute, is a fixture in China Wei Kaide comprehensive inspection and testing, is a contest Hua Wei Kaide intelligent LED lighting fixtures and other fixtures, the next, Hua Wei Kaide underground parking intelligent LED The luminaire will open the huge market of design institutes.
