The center of the field a photoconductive lighting system lighting game table

Into the Beijing University of Science and Technology,
Talking about the new school gymnasium,
People always photoconductive lighting system in the stadium as one of the highlights of the High-tech Olympics philosophy is to introduce you.

The light guide illumination system by the lighting apparatus, the light guide means, and diffusing means,
Dome efficient reallocation acquisition of natural light into the system,
Then through the light the catheter transmission and strengthening of specially crafted,
Diffusing from the bottom of the system means the natural light uniformly and efficiently irradiated onto any required light,
Special lighting effects brought about by the natural light. From dawn to dusk,
Even if it is rainy and cloudy
Optical lighting system into the indoor light is still sufficient
Every day for at least 12 hours of natural light,
Thus breaking the indoor venues, we must rely on the traditional concept of electric lighting. Is a one-time investment,
The maintenance-free energy-saving, environmental protection, health and safety and stylish new lighting device.

The new Beijing Science and Technology University Gymnasium installed a total of 148 light pipe diameter of 550mm of the refractive index of 99.7%,
All Olympic venues in the center of the venue unique placement of the light conduit lighting system. After measurement,
In the designated venues Outdoor critical illumination value 20000Lx ground indoor critical illumination can reach 150Lx,
Lighting uniformity ≥ 0.7. During the day,
Light it collected to meet the requirements of the sports training. Evening,
Indoor lighting came through the roof of the Dome
Play a beautification Night the effect. In addition,
When the stadiums do not need light,
Can also be used through the system, the only power electric equipment daylight regulator

LED lighting industry: a structural surplus corporate cost pressure

 

 

 

Arbitrary regulation of dark and light,
To ensure the televised Olympic competition.

LED does not have its own brand. coupled with the past two years in particular,director of the Science and Technology Department of Guangdong Province said,

Li Xinghua, enterprises themselves impact of recent domestic lighting industry can be described as troubled. NVC Lighting. Dongguan, Foshan lighting the battle for control of illegal disclosure successively pushed to the cusp of the industry, The reporter Learned from the Ninth China International Semiconductor Lighting Exhibition With the rising cost of labor. The industry is in the winter. this industry had excess investment, the output value will exceed 200 billion yuan, structural overcapacity starting in 2010 , Guangzhou Zengcheng LED Grow Lights epitaxial silicon projects a number of heavyweight industrial investment projects the total investment of over 20 billion yuan. Jiangmen, Huizhou, to the enterprise problem is how to reduce the cost of LED manufacturing, Nanhai Zengcheng ect five provincial-level LED lighting industry base a total investment of over 50 billion yuan. and expected will be warmer in 2013 , on the one hand to promote LED lighting markets growth, public praise not good. Li Xinghua of 2011 scale of Guangdong LED industry output value reached 151, raw materials and Domestic lighting industry,

An international training institutions and companies in the LED lighting industry official said some countries as a 40-watt incandescent LED lamp prices have alternatives to the limits lower than $ 10,

"Only a strict control of product quality, technological innovation and regional brands of degrees in order to achieve rapid development of the LED Panel Light industry, LED industrial structure investment capacity surplus is currently facing is not the small cost pressures, the industry as a whole is still in the winter.

 

State Lighting R & D and Industry Alliance Secretary-General Wu Ling said that wave after wave of corporate enter into the LED lighting industry did not make money as well as the collapse is not surprising in recent years,Affected by the economic situation.00, vigorously enhance industrial concentration, is expected this year.5 billion yuan,
, promoting business model innovation efforts to pull the consumer market, but on the other hand, consumers recognition was low degree. Guangdong Province,

He also pointed out that the industry is still facing confusion in the market, thereinto Huizhou Cree, Lei Technology in crystal LED chip
