Temple II successfully launched, Pa a Pa will LED lighting to do those things in the sky

September 15 22:4, in this month Langfeng clear night, China’s first full sense of the space laboratory “Temple II” successfully fly to space.
But you know the spacecraft and space stations used in the LED lights it?

whether it is spacecraft or cabin, this LED lighting is essential, then the problem came, aerospace LED lighting with what the premise? Need to solve any problems
? 112199887121121991121121121998871111219987181121998238711219988711112887231 outside the space environment, you have not experienced the concept of that really, the outer space environment, high vacuum, weightlessness, strong radiation, cosmic rays, we look at the astronauts bulky clothes to know, people still so, that lights do not
said.
So this lamp must also be able to withstand this temperature environment.
Second, the first is safe, and then strong, safe is not damaged, you say on the repair, the ground is a normal matter, to the space maybe spend a whole day, of course, people walk more effort ah.
This is the heat problem and effect, can not occupy the spacecraft’s energy, especially as this high-power, extravehicular high-power lighting equipment rendezvous with the use of docking lights, it not only for astronauts to illuminate the rendezvous and docking target
, But also for the audience on Earth to witness this exciting moment to provide a magnificent light and shadow effects.

such previous Shenzhou nine, Temple of environmental test equipment temperature increase from the original -15 ℃ ~ 50 ℃ to -35 ℃ ~ 70 ℃, environmental testing time is also multiplied, so the equipment used in the meta
Equipment and raw materials, the quality level has greatly improved, the standard level of domestic components significantly increased, the difficulty of thermal design of equipment increased.

for rendezvous and docking heat lamp design, it is necessary to solve the heat problem hundred pieces of LED light emission when a high-density, but also to ensure LED work temperature does not fall below the threshold of its use, but also to ensure that does not become a rendezvous and docking lights
spacecraft cabin leak source “design difficulty is evident .

finally to give you a grilled steak LED lighting use in space history:

September 2008

astronauts to walk in space as well as the image of God for the seven Chinese spacecraft
shooting illumination system, is the world’s first use of LED light source as a manned spacecraft lighting systems, but also for the Chinese mainland’s first extravehicular space lighting system .

March 2012

Shaanxi SG new energy Co.
Japan’s Mitsubishi chemical Corporation jointly, Nakamura scientific instruments industry Co., Ltd., Beijing Yuji Science and Technology development Co., Ltd. jointly developed LED phosphor production line project settled in Xi’an aerospace base .

June 2012

Chinese Temple God nine and docking, which marks
China has mastered the key technologies of docking between different spacecraft and will take a big step towards building China’s own space station.
The rendezvous and docking using high-power LED as a condenser light source, which is the first time at home and abroad.

August 2012

Arizona N power Global Technology Co., Ltd. (NthDegree) signed a contract with NASA, the space will become the ink light LED light source.
Shenda Hao Rui company’s new LED epitaxial wafers and chip production projects in Xi’an space base trial production success.
The finished lamp made from this type of epitaxial wafers converts 1 watt of electric energy into 100 ML (light unit) of light energy, which is about 3% higher than that of the current global market.
The project technical team leader is China “chip godfather” Dr. Zhang Rujing.

August 2013

NASA Boeing’s CST-100 spacecraft flight state assessment tests, LED equipment settled Boeing spacecraft capsule.
One feature of the CST-100 spacecraft is the purple light emitted inside the cabin.
This is Boeing’s “sky interior”, the use of LED lighting to create a more peaceful environment for astronauts.

October 2013

NASA decided to provide the International Space Station astronauts in space planted edible vegetables, the first six will be cultivated lettuce, pink LED lights provided by the photosynthesis required light.
Space lettuce 28 days after planting can mature, to the extent of edible.
Past tests have shown that zero-gravity environments do not affect the growth of these vegetables.
Growing ingredients in space can solve the difficult problem of fresh food supply in future long-distance space travel.

September 2014

NASA and Boeing signed a $ 42 million contract for NASA for the manned space project to build commercial CST-100 manned spacecraft.
The CST-100 will use Boeing’s LED “Sky Lighting” technology.
Sanya Optoelectronics and Shanghai Aerospace Electronic Communications Equipment Institute signed a “strategic cooperation agreement.”….
Shanghai Aerospace Electronic Communications Equipment Research Institute is China Aerospace Science and Technology Corporation specializes in aerospace electronics technology research, product development and production of specialized institutions.
