Look at the LED lighting design requirements from Shenzhen Airport accident

Shenzhen Airport major accident occurred in March this year, recently released survey results. March 1 afternoon, the Shenzhen Airport T3 viaduct turn departure hall occurred about 50 meters of major accidents. Yang Xi driving a Mercedes car to the airport along with her boyfriend Wu, when the vehicle line to the airport viaduct departure platform corner suddenly out of control, into the right side of the fence to continue driving, crashed into the guardrail side sightseeing personnel. Accident has killed nine people (of which five people were killed, the other four people, including the driver to the hospital died), 23 people were injured.

The airport is a very important public places, as LED lighting professional people, we can think: how to make beautiful airfield lighting, security and energy?

Based on "Architectural Lighting Design Standards" (GB 50034-2004) and "Traffic building electrical design specifications" (JGJ 243-2011) for terminal value machine hall, lounge and other areas to determine the illumination design specifications, to the gate, in island regions additional counter spotlights and fluorescent lighting, make the desktop average 500lx, ground average 200lx.

1) Since the interior space of the terminal area is large, the number of lamps to their needs, as well as the light source power consumption will have relatively large, for big space lighting choice for lighting source noted that in addition to beautiful and reasonable light distribution , but also give full consideration to their energy efficiency. In addition to the choice of a light source based on the color temperature, and environmental requirements of color, but also in accordance with efficient, long-life choice principle lamps.

2) large space according to the choice of quality lighting sources and efficient Metal Halide (requires Ra≥80, Tcp ≈4 000K ~ 4500K, the color should not be greater than ± 200K, the average life expectancy of not less than 10 000h), the choice of energy-saving inductor ballast , a total harmonic standards should meet the requirements of national standard GB 17625.1-2003, the average life expectancy of not less than 50 000h, the ballast factor ballast and energy efficiency not lower than the national energy efficiency standards for ballasts "energy evaluation value."

3) According to large spaces lights’ all-day running and maintenance time is short, to maintain volume and other characteristics, in order to minimize operating costs, so the lamps should be of high quality, efficient products, and shall comply with the GB 7000 series of standards, through the CCC requiring sturdy and durable materials, safety and reasonable structure, beautiful and durable, to ensure structural strength, protection level, temperature and other properties required for use within the roof ceiling lamps protection class IP44 luminaire selection.
