Osram unveils single-chip Dragon LEDs operating up to 2 A
The new Diamond Dragon will contain a 2 x 2 mm chip and will produce 250 lumens at a typical current of 1.4 A.
The LED is based on a 2 mm2 chip manufactured in Thin-GaN technology with chip-level phosphor coating. Other Dragon and Ostar packages from Osram use 1 mm2 chips.
The LED produces a luminous flux of 250 lm at a typical operating current of 1.4 A in continuous operation, says Osram. The corresponding color temperature was not discussed. The maximum rated current is 2 A.
These properties enable the LED to be easily integrated for example in small spotlights, retrofit applications and recessed ceiling luminaires, where they can even replace small halogen lamps.
The typical power rating of the Diamond Dragon is in the 5 to 8 W range. This LED forms a link between Osram’s 1-3 W single-chip LEDs (Platinum Dragon) and the 10 W, multi-chip Ostar LEDs.
The Diamond Dragon will be compatible with the other Dragon footprints and can therefore be integrated in existing designs without modification.
Osram says that the new LEDs will cover the entire white range and will also be available in all other colors. They will therefore be suitable for both indoor and outdoor general lighting applications and also for the automotive sector in daytime running lights or rear fog lights.
