Single-Chip SMT LED Achieves Brightness of Up to 250 Lumens
OSRAM Opto Semiconductors announced the arrival of the super-bright Diamond DRAGON LED. It achieves brightness of up to 250 lumens, and will be available in whites ranging from 2,700K through 6,500K as well as all monochromatic colors. With this technology, OSRAM will offer an LED that is appropriate for indoor and outdoor general lighting, automotive forward and signal lighting, and other high performance applications. The low thermal resistance of Rth = 2.5 K/W provided by the 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 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. These LEDs can withstand high drive currents without damage. Typical (binning) current is 1.4A, with a maximum current of 2.0A. 50,000 hours is the typical expected lifetime. This robust package incorporates a silicone lens and is fully SMT compliant. This high-brightness single-chip device uses the company's ThinGaN® chip technology along with chip level conversion. The Diamond DRAGON is rated for 5W to 8W input power.
