LG Innotek succeeded in developing a light emitting diode (LED) for illumination that can withstand temperature up to 300 degrees, and will begin to roll out the product at the end of this month.

LG Innotek announced on January 18 that the company would mass-produce the Advanced Flip Chip LED Package with light efficiency of 220 lm per watt. The flip chip LED package is a light source directly attached to a PCB substrate without a connection line between chips. The new product’s light efficiency reaches the world's highest level.

The flip chip LED package has attracted attention since three years ago as it has no defects and has an excellent capability for protection against heat. But its low optical efficiency has made lighting equipment companies ask for an improvement in quality. "We were able to raise luminance efficiency to 220 lumens per watt by changing chip structure design and applying semiconductor mounting technology," an LG Innotek official said. "This is a level that satisfies lighting companies’ luminance efficiency requirements of lighting companies."

Above all, its most salient feature is the fact that brightness and light efficiency are maintained even at a high temperature of 300 degrees. When a lighting device is turned on, its chip temperature rises to 250 degrees Celsius. LG Innotek's product is durable enough to withstand such a high temperature. Its price is only half of that of competitors at home and abroad so the product can win a price war with those of Chinese companies.
