Innovation of science and technology, wuhan yangluo changjiang river bridge LED solar lamps and lanterns and system application

Wuhan yangluo changjiang river bridge is is a country '15' during transportation key construction projects, is wuhan city highway control engineering, as well as ( North) Beijing-zhuhai ( The sea) , shanghai-chengdu national highway main throat, at the same time, or hangzhou to lanzhou key trunk highways and been two transverse link 'in hubei province highway main skeleton. The bridge main USES the mainspan twin towers single span suspension bridge is 1280 meters, it is also the first suspension bridge of wuhan city, the span of the third, in the eighth in the world, with its construction is very difficult, high technical content for the attention from all walks of life.

LED lamps and lanterns and system application of wuhan yangluo changjiang river bridge is an important part of the project. By LED lighting and control system, the outline of yangluo changjiang river bridge, majestic momentum, build strong visual impact, from two aspects of physiology and psychology, bring the audience into the bridge architecture environment.

the key technology and innovation points are:

1, mainly adopts new type 350 ma LED light source; 2, according to the bridge building local cultural elements and artistic effect, abstracts ChuYun chimes element bridge appearance of lamps and lanterns; （ Appearance patent) 3, outdoor high in the sky, LED lamps and lanterns DMX signal control length of 4500 meters, single point level 256 change; 4, using H integration of cooling channel design, to meet the requirements of the mm / 6400 mm * W 5, taking into account the surface tension of water abnormity waterproof rubber gasket 6, lamps and lanterns of balance cavity pressure differential vent plug (in vivo and in vitro The patent for utility model) 7, induction thunder and lightning prevention and electrical design of ESD, tolerated 800 a ( 8 a / 20人) The surge. 8, lamps and lanterns of internal communication decoding module, has anti surge anti-jamming circuit, with slope, open/idle failure protection function, as well as 15 kvesd protection. 9, take index between optical stripes and bite thin flower design, so that half of the mixed mask mixed uniform light, and reduce the loss of the light output; ； 10, reliability requirements for engineering site, using the simplified engineering wiring integration design, LED lamps and lanterns of internal integration full voltage of switching power supply, constant current drive, DMX decoding module; Application and benefits:

yangluo changjiang river bridge on the main cable, every 8 meters interval, installation of LED lamps and lanterns of bridge; Every 160 meters installed DMX repeater, the focus on the main control room, PC software running dazzle colour lights, fiber optic will move light signal, sent to the DMX main console; Acceptable DMX512 signal lamps and lanterns, single point's class of 256.

power 30 w bridge lamps and lanterns, LED RGB light every 8 w, compared with the traditional technique of expression, 1, full color, pure, save electricity by 50%; 2, life by 6 times of lamps and lanterns; 3, reduce maintenance costs 100000 yuan/year; Since operation, little maintenance, maintenance than traditional lamps and lanterns to decrease by 90%; Save a lot of maintenance costs, every day visitors an endless stream, comprehensive economic benefit and social benefit is obvious.
