Technical Datasheet DS52 power light source LUXEON Portable PWT ® Introduction LUXEON® Portable PWT1, is the smallest power LED designed for consumer applications. The new emitter generates 26 lumens at 350mA from a package size of only 2.0 x 1.6 x 0.7mm, providing marketleading light output for its size along with a 2,000hour life and uniform white light produced by Lumileds’ patented conformal coating process. LUXEON Portable PWT1 is roughly 75% smaller than other LEDs with similar light output and delivers 4.5 times the lumens/mm2. This enables designs with smaller optics, smaller form factors and less weight than ever before. The nearly perfect lambertian radiation pattern enables efficient optical designs. Surface mount capability allows for simplified manufacturing and it offers the toughest electrostatic discharge (ESD) protection in the industry with an 8kV ESD protection chip. Features Lifetime of 2000 hrs 2mm in size Color temperature of 6500K Advanced protection against electrostatic discharge (ESD) Instant turn on time High efficacy Typical Applications Ideally suited to portable lighting and lighting for consumer products Table of Contents Product Nomenclature . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 Average Lumen Maintenance Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 Environmental Compliance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 LUXEON Portable PWT Typical Design Parameters . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 Ordering Information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5 Physical Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5 Operating Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5 Electrical Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5 Typical LUXEON Portable PWT1 Electrical and Light Output Characteristics . . . . . . . . . . . . .6 Consolidated Design Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .7 LUXEON Portable PWT Technical Datasheet DS52 (5/06) 2 Copyright 2006 Lumileds Lighting. Product Nomenclature The part number designation is explained as follows: LXCLABCD Where: A — designates radiation pattern (value P for Lambertian) B — designates color (see Lumileds AB21) C — is a running number reserved for future products D — is a running number reserved for future products Average Lumen Maintenance Characteristics Lifetime for solidstate lighting devices (LEDs) is typically defined in terms of lumen maintenance—the percentage of initial light output remaining after a specified period of time. Lumileds' testing has verified that LUXEON Portable PWT products will deliver, on average, 70% lumen maintenance at 2000 hours of operation at a forward current of 350 mA. This testing is based on constant current operation with junction temperature maintained at or below 55°C. This performance is based on internal LUXEON reliability testing. Observation of design limits included in this data sheet is required in order to achieve this projected lumen maintenance. Environmental Compliance Lumileds is committed to providing environmentally friendly products to the solidstate lighting market. The LUXEON Portable PWT is compliant to the European Union directives on the restriction of hazardous substances in electronic equipment, namely the RoHS directive. Lumileds will not intentionally add the following restricted materials to the LUXEON Portable PWT: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
