LEDs offer high density in a small surface

LUXEON CoB Core Range (Gen 4) LEDs from Lumileds are available at Mouser Electronics. These LEDs 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 center beam candlepower (CBCP) in narrow-beam (less than 20-degree) spotlight applications.

These fourth generation of CoB Core Range LEDs feature a single optical LES of 13, 15, or 19mm that provides high flux densities and high efficacy.

They are offered over a colour temperature of 3000K to 4000K and CRI of 80 or 90. The CoBs provide the industry’s low 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 3-step (80 and 90 colour index rating) MacAdam ellipse to ensure optical performance in retrofit lamps and spotlight applicationsThey are all hot-tested at 85 degrees Celsius, so that luminaire design is simplified and testing can be minimised.

The LEDs are designed for a broad array of general purpose and directional lighting applications including architectural lighting, downlights, high bay and low bay fixtures, and spotlights.
