German use led studio lighting technology to sent it to the Office of the "blue sky"

Work in the blue sky and white clouds, the yearning of many office employees.Fraunhofer, Germany, labor management and Organization Research Institute (IAO) of the researchers and an LED technology company developed a special roof light. Thelight source simulated wind cloud shift, led studio lighting, the light changes the state of nature, give rise tothe feeling of the vast sky.

The new light levels by 50 and 50 cm in size porcelain tile to cover the entire roof. Each tile has 288 LED lights on the circuit board, circuit board fixed in the roof, the LED high bay  lamp 30 cm equipped with a white sub-diffusion membrane, making the surface shiny anduniform, led studio lighting, can not see points of light. To get the required spectrum, the researchers usedred, blue, green and white LED can produce more than 1600 million light colorcombination. In addition, white light-emitting diode power consumption less than thecolor, the more energy efficient.

Focus on the development of virtual sky is to replicate the light of the cloudy weather. To this end the researchers on the natural light to do research, mastered the spectrum ofchanges in the clouds move with speed, then the LED to simulate dynamic. Researcherscommitted to enough light changes in order to promote indoor workers clear-headed,without its direct feel of the light changes, avoiding fragmentation of the work of attention.

Technical team to do a preliminary investigation: 10 volunteers to work four days in the30X60 cm roof light: the first day of using static light, slow light changes the next day, the third day changing speed, led studio lighting, the fourth day by the volunteers on their own choice, the finaleight chose the light of rapidly changing. The survey results show that users feel comfortable with the dynamic lighting.

The researchers have manufactured a 34 m2 large “virtual sky” prototype installed a totalof 34,560 Dimmable LED Light Bulbs. The full power of “sky” light of 3,000 lux, while the actual use of500-1000 lux is sufficient. It is reported that this technology will be on display inHannover, led studio lighting, Germany, IT Expo (March 2012).
