Mouser stocks Lumileds’ Luxeon CoB range for density in small LES

Distributor, Mouser Electronics stock Luxeon Chip on Board (CoB) Core Range (Gen 4) LEDs from Lumileds. They offer high flux densities in a small light emitting surface (LES), enabling double the luminous flux of the third generation of Luxeon CoB Core Range devices.

The high-density CoBs can achieve the highest centre beam candlepower (CBCP) in narrow-beam (less than 20 degree) spotlight applications.

The fourth generation of Lumileds LUXEON CoB Core Range LEDs feature a single optical LES of 13, 15, or 19mm that provides high flux densities and high efficacy. Luxeon CoB Core Range (Gen 4) LED arrays are offered over a colour temperature of 3000 to 4000K and CRI (colour rendering index) of 80 or 90. The CoBs provide the industry’s lowest thermal resistance, enabling smaller heat sinks and optics for lower overall system cost. The MCPCB substrate is also more robust than ceramic substrates that are subject to cracking upon assembly or use.

All the Luxeon CoB Core Range LED devices are binned with a single three-step (80 and 90 colour index rating) MacAdam ellipse for use in retrofit lamps and spotlight applications. Luxeon CoB Core Range LEDs are all hot-tested at 85 degrees C, so that luminaire design is simplified and testing can be minimised.

The Luxeon CoB Core Range LEDs from Lumileds are designed for a broad array of general purpose and directional lighting including architectural lighting, downlights, high bay and low bay fixtures, and spotlights.
