RS Components (RS), the trading brand of Electrocomponents plc (LSE:ECM), the world’s leading high service distributor of electronics and maintenance products, has announced availability of high-power LUXEON ultraviolet (UV) LEDs from Philips Lumileds. Featuring the industry’s smallest footprint of just 2.2mm2, the high-power emitters are one-fifth the size of competing ultraviolet and violet LEDs currently on the market.
The LUXEON UV LEDs can be assembled in tightly packed arrays with spacing of only 0.2mm to enable the construction of high-power-density (W/cm2) UV systems. Offering a maximum drive current of 1A – for more flux per LED – the high-efficiency devices cover the 385 to 410nm 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 LEDs 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 (AlN) substrate, thereby delivering superior thermal performance. Thermal resistance is as low as 3.5K per Watt.
