(Santa Clara, CA) — OSRAM Opto Semiconductors announces the arrival of Diamond DRAGON®. This new super-bright LED will launch in January 2008. Diamond DRAGON achieves brightness of up to 250 lumens, and will be available in whites ranging from 2700K through 6500K as well as all monochromatic colors. With this latest advance in technology, OSRAM will offer an LED that is ideal for indoor and outdoor general lighting, automotive forward and signal lighting, and other high performance applications.
The exceptionally low thermal resistance of Rth = 2.5 K/W provided by the Diamond DRAGON's SMT package allows heat produced in the chip to be efficiently removed from the LED package. The maximum junction temperature of 175°C makes these LEDs extremely 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.
Diamond DRAGON LEDs can withstand high drive currents without damage. Typical (binning) current is 1.4 amps, with a maximum current of 2.0 amps. 50,000 hours is the typical expected lifetime. This robust package incorporates a silicone lens and is fully SMT compliant. The Diamond DRAGON footprint is compatible with previous devices allowing upgradability for current Golden and Platinum DRAGON users.
This high-brightness single-chip device uses OSRAM’s ThinGaN® chip technology along with chip level conversion. The new Diamond DRAGON is rated for 5 — 8 Watt input power and enhances OSRAM’s already large power LED portfolio which includes 1 to 3 W LEDs (Golden and Platinum DRAGON®) as well as the 10 W and up line of OSTAR® devices.
