RS Components has announced availability of high-power Luxeon ultraviolet (UV) LEDs from Philips Lumileds. Featuring a footprint of just 2,2 mm², they can be assembled in tightly packed arrays with spacing of only 0,2 mm to enable the construction of high-power-density (W/cm²) UV systems.
Offering a maximum drive current of 1 A, the high-efficiency devices cover the 385 to 410 nm spectrum and are undomed for precise optical control. They are ideal for a wide range of applications including ultra-violet curing, counterfeit detection, spectroscopy, medical, security/forensic lighting and speciality lighting, such as aquarium lighting and blacklight for nightclubs.
The parts are based on the Luxeon Z surface-mount design, which implements flip-chip assembly and sets the UV die in direct contact with the thermally conductive aluminium nitride substrate, thereby delivering superior thermal performance. Thermal resistance is as low as 3,5 K/W.
