God seven cabin light source LED system of Shanghai R & D and manufacturing

The Shenzhou 7 spacecraft will be the first time the Chinese people into space, it is reported that the astronauts use a set of LED lighting system, developed by scientists in Shanghai. Future monitoring of the transport of spacecraft lighting, will use this LED lighting system.

Although this report haven reports, system than the theatre spotlight, but people did not dare to look relatively bright. Twenty-four LED small bulbs are arranged in the base half A4 paper size, a bit like a sucker covered with large octopus legs.

The energy consumption of this lighting system is surprisingly small, only twenty-seven watts, usually a light bulb of a mere twenty-five watts can only dimly lit a small bathroom.

Chinese Academy of Sciences, Shanghai Institute of Technology Physics researcher Zhang Tao said that in the past in the international space in the light of the gas discharge metal halide lamp, power consumption, high pressure, high heat, is not ideal for space lighting light source. In recent years, the development of LED lighting is very fast, not only high efficiency, but also safe and reliable, it is possible to replace the metal halide lamp, a new generation of space lighting source.

He said that the outer space environment is very bad: in the face of the sun when temperature over one hundred degrees Celsius, carrying the sun when the cold of minus fifty degrees Celsius, but also bear the universe all kinds of high-energy particle bombardment uninterrupted, all kinds of mechanical extreme environment and spacecraft launch phase.
