Leader of Solid State Lighting

NeoPac Lighting Inc., a Taiwanese LED-packaging startup, has come up with a patented solution to the technological bottleneck that has kept most of its peers from boosting LED-lamp illumination by any significant amount.

The core of the innovative solution is an efficient heat-dissipation technology called a “heat pipe,” which NeoPac claims can maintain the junction temperature of the positive and negative electrodes of LED chips within a low range. This is a vital consideration. “Heat is the major killer of LED illumination,” explains Jeffery Chen, the company’s chairman and CEO. “The higher the heat is, the faster the brightness decays.”

The heat pipe is not a new concept in the PC industry, which uses it to dissipate heat from personal computers. However, Chen stresses, “We’re the first LED packager to apply the concept to LED lamps, and to have succeeded in reducing the junction temperature.”
