Exellent Luminous Efficiency and Thermal Conductity
Using the excellent heat transfer characteristics of transparent ceramics (thermal conductivity~40 W/mK), and matching coefficient of thermal expansion (coefficient of thermal expansion~6-10, CTE) to evenly coated on both sides of phosphor technology (Conformal coating). As well as the development of anti-reflective film (Anti-reflection coating, ARC) makes LED chip to increase 20% more efficiency than posted film type LED and integrated type LED in operation of light existing.
Due to achieved increasing external quantum efficiency and relatively reduced the heat of chip layer, a nd it could develop self-radiation type of lamp or pendant when operating under 3W. LeTES series products of features are high lm/W, therefore it can easily develop out 3W 400~500lm light source in cold state. LeDiamond Opto presents the competitive packaging technology of such outstanding performance LED components, and creating the unique thinking from industry.
