OSRAM listed for lighting 250lm white LED

Germany OSRAM Opto Semiconductors (OSRAM Opto Semiconductors GmbH) announced that it would start selling a chip from the beginning of 2008 250lm can be obtained (drive current 1.4A) luminous flux of the white LED Diamond DRAGON". The input power of the product is 5 ~ 8W, for the level of "Platinum DRAGON" and 10W "OSTAR" between 1 and 3W.

The new product uses a large 2.5K/W (11mm * 6.7mm * 4.2mm), with a significant reduction in the thermal impedance of the SMT package, which can be used for small space and difficult to cool due to the welding temperature as high as 175 degrees centigrade. In addition, due to the adoption of a silicone resin lens, the reflow soldering furnace can be used for welding. The life of the new product is more than 50 thousand hours, the luminous efficiency is 52lm/W (25 DEG C, driving current 1.4A). In addition to white, the future also plans to increase the other colors, such as bulb.

The company plans to provide the product to the spotlight, embedded ceiling lamp, car daytime running lights DRL (Daytime Running Light), as well as the use of rear fog lights, etc..
