On August 18th, the CTO Conference of the 9th High-tech LED Industry Summit held in conjunction with the 2012 High-tech LED Exhibition was successfully held in the AB meeting room of Hall 5 of Guangzhou Poly World Trade Center. The forum agenda was based on the upper and middle of the LED industry chain. The downstream is divided into three special sessions. The CTOs and executives of well-known enterprises in the LED industry chain are invited to share the latest cutting-edge technologies in the industry and discuss the technological development trends of the upper, middle and lower reaches.

Yan Chunhui, president of Yaweilang Optoelectronics, analyzed the bottleneck that the upstream can break through. He reviewed the history of the development of nitride LED technology. With the improvement of LM/W, LED applications continue to upgrade and the market continues to expand. The goal of the upstream breakthrough is high luminous efficiency (lm/W) + low cost (lm/$) + high color rendering + high reliability. The prior art is based on increasing lm/W to increase the space of lm/¥+Lm/W, which is close to saturation. For the lighting market, more than 200lm / ¥, lm / W technology is difficult to match.

Finally, Yan Chunhui proposed the direction of the extension of the square lumens: IEQ improvement, material defects fell into the key; Droop decline, LED structure design, chip heat dissipation is the key; LEE upgrade, LED structure light absorption must be minimized. At the same time, Yan Chunhui also announced the production of near-ultraviolet LED chips by Yaweilang. The internal quantum efficiency has exceeded that of blue LEDs, and the external quantum efficiency is over 50%.

Low smoke zero halogen flame retardant wire refers to cable that does not contain halogen(F, Cl, Br, At). Its jacket is made up of some very special materials which are non-halogenated and flame retardant, emitting limited smoke and no halogen when exposed to high sources of heat. It can have various levels of flame retardancy and mechanical strength. The flame retardant performance of the cable is superior, very little smoke during burning, no corrosive gas escape, thereby protecting public health and avoiding any possible damage to electronic equipment. For this reason, its use is highly recommended for public places and for all installations where it is necessary avoid to electric interference of nearby circuits.



  • Large tensile strength
  • Good weatherability
  • Non moving performance
  • Good softness
  • No toxic smoke during burning
  • Excellent elasticity and stickiness
  • Great resistance
  • Easy installation
  • Long life span
