Platinum Dragon series LEDs from Osram

Osram Opto Semiconductors has expanded its Dragon series line of high-power LEDs with the Platinum Dragon for applications that call for high brightness in a small space.

The Platinum Dragon LED produces white light at 75 lumens from an operating current of 700mA (30 lumens per watt), which makes it the brightest single-chip, high-power LED in the Dragon series. Potential efficiencies range from 30 to 50 lumens per watt depending on actual application drive current. The high-power ThinFilm and ThinGaN chips, better thermal connection between the chip and the package, and optimum heat dissipation of the SMT package itself, all contribute to a significant boost in output, said the company.

The Platinum Dragon offers the same design and dimensions as the Golden Dragon package, with a 1.8mm height, but can withstand twice the input and therefore a higher operating current. This means more light in the same amount of space, said the company.

The high-brightness feature opens up new opportunities in applications such as flashlights, bicycle lamps and flashing blue lights for emergency vehicles as well as existing applications such as traffic lights, flashing warning lights on building sites, reading lights in cars and aircraft, and medical lamps.

The Platinum Dragon is priced at less than $3.
