DoubleDome LEDs

HAMBURG, Germany, April 29, 2010 — Sharp Microelectronics Europe has announced the DoubleDome series of LEDs that incorporate three white high color rendering, high-performance LEDs.

The series’ light conversion layer is based on a two-phase development procedure developed by the company. A layer of phosphorous for the conversion of white light is applied in a first step. The second step involves the installation of the globe top made from transparent silicone, which makes light extraction possible without spreading loss.

A ceramic plate acts as the LED carrier material instead of the plastic materials that are traditionally used, offering efficient heat dissipation and helping to keep the required cooling element small.

The series is available in three different shades of white—warm, natural and pure white.

They are suitable for LED backlighting of LCD televisions and surface lighting, including ceiling lights of office rooms and factories. Other applications include street, architectural and display lighting.
