The night is coming.

Walking through the avenue between the Expo Venue, it looks like I have entered a wonder land. Most of the lighting in the park is from LED components, the full name of which is “light-emitting diodes”. It is a kind of solid-state semiconductor which can transform electricity into visible light. It is hundreds of millions of LEDs that light up the Shanghai Expo Venue. Among them, outdoor led spotlights play a significant role.

Coca-Cola Museum is next to the “Oil Cube”. Visitors prefer to call it “Coke bottle”. A 15 meters high giant Coke bottle embedded in the center of the venue, the director of this building indicated that it is the biggest building displayed by outdoor led spotlights in the world. The total weight of the entire bottle is over 10 tons, the internal frame constructions of which are all made by steel. More than 3000 German-made LED light bars were installed in everywhere in this building. Hundreds of outdoor led spotlights are embedded in the surface the “Coke bottle”. During the night, flags from countries around the world and sign of the Expo will be flashing magnificently on it.

The “magic cube” set up by Shanghai Corporate Pavilion just beside the “Coke bottle”, this “unattractive” building (at the daytime) seems has nothing to boast about. However, more than 20,000 LED light bars are embedded on its surface, with a total length of 110,000 meters. All these light bars are controlled by 129 independent controllers. Designers considered to use led high bay as the landscape lighting of this building, but gave up this idea finally.

Interview with this reporter, recalling venture, Sony light, chairman Zhang poignantly: “If we had not resigned, I might still work in the bank; If there is no access to the rare earth phosphor, I might still ITindustry hard; an ongoing subway project did not encounter difficulties, outdoor led spotlights, I might never have encountered a new LED lighting market opportunities, and progress in the field of LED lighting. ”
In 1995, Zhang left the bank to start a business. At that time, the golden period of rapid development of IT industry, the computer market demand. Zhang ‘s business is booming,as the southwest regional distributor for one brand of computer, outdoor led spotlights, within a very short time to dig into the pot of gold. Glad to calm down and Zhang began to think about a problem:good product sales, is its brand and technology behind the product, its agent “wedding dress” for others as their own brand.
Reflection, outdoor led spotlights, Zhang Ming to make a choice: Try a diversified investment out of one of their own way. However, in the end what the industry development, led high bay,  Zhang is difficult to make a clear positioning.
A chance, Zhang first exposure to the rare earth long afterglow phosphor. This material can light energy received and stored, and then in a very long time to release a newoptical storage materials in visible light. The absence of radiological hazards of this material cause for concern since the 1980s. Learn from the experts of Tsinghua University and other universities and research institutes, Zhang have a new understanding of the rare earth. Zhang keenly felt the huge business opportunities, outdoor led spotlights, he decided to go to this new industry of the rare earth long afterglow phosphor, the company changed its name to the Sichuan Sony light.
After several experiments, the research team, led by Zhang made ​​the results. In 1998,independent research and development of the Sony light rare earth long after glow phosphor was born, in order to protect their innovations, Zhang Ming, outdoor led spotlights, find experts to help guide the drafting patent application, and submitted a patent application in 1999. In2003, the company’s first patent application to obtain authorization.
