Osram Opto Semiconductors plans to launch its Diamond Dragon super-bright LED in January 2008. Diamond Dragon achieves brightness of up to 250 lumens, and will be available in whites ranging from 2700 K to 6500 K as well as all monochromatic colors. This super-bright LED targets indoor and outdoor general lighting, automotive forward and signal lighting, and other high performance applications.

Built on OSRAM's ThinGaN chip technology, the Diamond Dragon LED is rated for 5-8W input power. The LEDs can withstand high drive currents without damage, said Osram. Typical (binning) current is 1.4A, with a maximum current of 2A. Typical lifetime is 50,000hrs. This package incorporates a silicone lens and is fully SMT compliant. The Diamond Dragon footprint is compatible with previous Golden and Platinum Dragon devices for easy upgrades.

According to Osram, the exceptionally low thermal resistance of Rth = 2.5K/W provided by the SMT package allows heat produced in the chip to be efficiently removed from the LED package. In addition, the maximum junction temperature of 175C makes these LEDs robust and enables applications where the LED cannot be easily cooled.

The combination of low thermal resistance and high junction temperature capability allows Diamond Dragon LEDs to be easily integrated in small spotlights such as MR-16's bulb retrofits, and recessed downlights, said Osram.
