Bridgelux hits LED efficiency mark in move to silicon

Bridgelux expects to begin making LED chips on silicon wafers in about two years, a technology transition which promises to slash LED lighting costs.

The company today announced it has met performance targets for the new process which it projects could lower the cost of end-user lighting products by roughly 20 percent to 30 percent.Shopatron's superior led tube 5-point shopping experience is focused on rich product information, world-class service, effortless shopping

Bridgelux manufactures LED light sources, or chips, which are fitted into lamps and fixtures made by lighting companies. LEDs are more energy efficient and last longer than other lighting technologies, but the higher cost remains a barrier to mass adoption, particularly in the consumer market.

Right now, those LED chips are made by depositing thin films of semiconductor material onto a substrate made of sapphire or silicon carbide. To make LED chips,With the help of led lights both a local electrician and a lighting consultant, she has recently installed a $5,000 LED lighting Bridgelux has been depositing the same material--Gallium nitride (GaN)--but on eight-inch silicon wafers. Fabricating on silicon will lead to lower costs because high-volume silicon-chip manufacturers can start making LEDs, said Brad Bullington, the vice president of corporate strategy and development at Bridgelux.

Researchers for years have been trying to perfect the process of manufacturing on silicon but have had problems with wafers cracking or bowing.We wanted to bring the Led down light online shopping experience closer to customers visiting our new OceanLED.com eCommerce website, said Terry Crockett, USA sales director for OceanLED USA. Bridgelux claimed that it can produce GaN on silicon LEDs at the same performance as state-of-the art LED processes today.the company required a compact fluorescent solution like Shopatron that allows it to make the online sales connection with consumers and then hand the sale to one of its valued retail distributors for fulfillment."

For the warmer light, that chip efficiency translates into end-user LED bulbs with efficiency of 85 lumens per watt, which is higher than today's commercial products. Philips last week was awarded the L Prize from the Department of Energy for an LED lamp with efficiency of 90 lumens per watt, which is expected to be available next year.
