brief introduction:
Germany's OSRAM Opto Semiconductors GmbH announced that it will start selling a chip with a white LED "Diamond DRAGON" with a luminous flux of 250 lm (with a drive current of 1.4 A) from early 2008. The input power of this product is 5~8W, which is the model between 1~3W grade "Platinum DRAGON" and 10W grade "OSTAR".
The new product uses an SMT package (11mm × 6.7mm × 4.2mm) with a thermal impedance that drops significantly to 2.5K/W. Since it can withstand soldering temperatures up to 175°C, it can be used in applications where space is difficult to cool. In addition, since a silicone material lens is used, it can be soldered by a reflow oven. The new product has a lifetime of more than 50,000 hours and a luminous efficiency of 52 lm/W (25 ° C, driving current of 1.4 A). In addition to white, other colors such as bulb colors are planned to be added in the future.
The company plans to offer the product to spotlights, recessed ceiling lights, daytime running lights (DRL (Daytime Running Light)" and rear fog lights.
