The Hong Kong-Zhuhai-Macao Bridge built with wisdom, LED street lights are the icing on the cake
BENWEI LED lighting: Known as the longest sea-crossing bridge in the world, the Hong Kong-Zhuhai Bridge, its supporting facilities have reached the world's advanced level, and the LED street lights used throughout the process are the icing on the cake.
The Hong Kong-Zhuhai-Macao Bridge, which connects Hong Kong, Macau and Zhuhai, will be opened to traffic at the end of 2017, with a total investment of more than 100 billion yuan. It integrates bridges, islands and tunnels with a total length of 55 kilometers. It is the longest sea-crossing bridge in the world. At the same time, it is also equipped with LED street lights and control systems that have reached the world's advanced level. The total number of LED street lights with modular ceramic heat dissipation is nearly 10,000 sets for the bridge, which can meet the needs of lighting brightness, lighting time and lighting color temperature when vehicles pass through the bridge, overcome the heat dissipation problem of street lights, and improve the life and reliability of street lights get the leap. Traditional street lamps usually use PCB boards, which generate a lot of heat in the lamp, and there is a natural conflict between the heat dissipation and the insulating layer. As a result, the heat in the lamp cannot be dissipated, and the LED junction temperature rises too high, shortening the service life of the lamp and reducing the cost. Reliability will also cause a lot of waste of resources. The LED street lights used on the Hong Kong-Zhuhai-Macao Bridge took the lead in abandoning the PCB board (aluminum substrate), but instead used a ceramic body, and the chip was directly welded on it. On the one hand, the ceramic itself is insulated to prevent leakage risks and non-ferrous metal pollution, and On the other hand, the heat dissipation has been fundamentally handled, and the service life has been greatly improved. The use of this technology can be said to be a new revolution in LED lighting.
LED street lights use technology to solve the lighting problem of the longest sea-crossing bridge in the world, which is the icing on the cake.
