Platinum Dragon LED - more current, more light

The Platinum Dragon LED produces white light at 75 lm from an operating current of 700 mA (30 lm/W), making it the brightest single-chip high-power LED in the Dragon series from OSRAM Opto Semiconductors. In terms of its design and dimensions, the package is the same as for the Golden Dragon but can withstand twice the output and therefore a higher operating current. This means more light in the same space.

The high-power thin-film chip, better thermal connection between the chip and the package and optimum heat dissipation of the SMT package itself all add up to this boost in output for the Platinum Dragon compared with the Golden Dragon. Because the operating current can be higher – up to 1 A depending on the colour – there is more light from the same unit area.

The Platinum Dragon is suitable for all applications that need high brightness in a small space. Torches, bicycle lamps and flashing blue lights for emergency vehicles are all good examples. Existing applications such as traffic lights, flashing warning lights on building sites, reading lights in cars and aircraft, and medical lamps can now be brighter without design modifications.

At a price of less than three dollars, the Platinum Dragon offers more lumens per dollar than any other LED.

Also, Lighting Science Group (LSG), a designer of energy-efficient LED lighting products, has incorporated Ostar LEDs from Osram Opto Semiconductors into the new LED-based R-16 compact floodlight.
