LED help large public buildings lighting

Today's lighting market, LED products for its energy-saving and durable, widely used, has become a popular trend. At first, LED was used as the light source of the instrument, and the LED of various light colors were widely used in the traffic signal lamp and large area display screen. Australia's capital, Canberra, a street has been used as a white light LED street lighting; China's urban traffic management lights are also used to replace the early traffic order LED lights. Now LED technology has become more and more innovative and mature, for energy-saving power of public buildings in the city, becoming the new trend of healthy lighting. In October this year, has just completed the Suzhou science and technology culture and Art Center, the unique curve of the facade of the lighting design is the biggest bright spot. In order to better show the unique landscape lighting effect at night, through the computer simulation experiment and model observation of various types of light source, the small size and controllable LED light source is the first choice. The facade of the building used a total of nearly twenty thousand sets of PHILPS LED lamps, is currently the largest LED lighting projects. LED is the heart of a semiconductor chip, a P type semiconductor and N type semiconductor. When the current through the wire to the chip, the electron will be pushed to the P area, in the P area of the electron and hole compound, and then will be in the form of photon energy, which is the principle of LED luminescence. In the Suzhou project, all the source is used LED chip PHILPS Lumileds high power 1W, the elegant 6R6G6B arrangement makes light overall uniform color, high saturation, color mixing, is extremely suitable for the landmark lighting. In the control system, the control of LED lighting control system is unique to Activemix, the night of the whole building can be colorful, four seasons scene "into" walls, the color of the gradient to the night the building with spectacular color, give a person with strong visual experience. LED most notable feature is the long service life, high photoelectric conversion efficiency, in the right current and voltage, LED service life can reach 100 thousand hours. The PHILPS lighting experts tailored for the project a special product, the lamp will be highly compressed to 21mm. Taking into account the curtain wall and the installation of the form, the effect of light on the light; at the same time, the full use of light on the metal grid reflection effect, so that the transmission of each hexagon uniform. Ultra-thin LED lamp contact with the metal surface, so the heat can pass through the metal curtain wall structure evenly and quickly dissipated, which solves the heat problem brought ultra-thin lamp body, to ensure stable operation of the LED lamp long time. LED small size, low power consumption, low heat, energy saving, environmental protection, strong and durable, etc..
