COB LEDs boast high thermal performance

The newly launched Lumileds Gen-4 Luxeon COB LEDs which enable smaller, simpler luminaires to deliver bright and vibrant lighting are in stock at distributor RS Components. With efficacy of up to 170lm/W, the industry’s smallest LES, and package thermal resistance up to four times lower than other COB LEDs, lighting designers using Luxeon Gen-4 LEDs can create new styles featuring denser arrays, smaller optics, and simplified construction.

In addition, colour consistency within a 3-step MacAdam ellipse gives freedom from binning to simplify component purchasing and luminaire production while ensuring uniform appearance from unit to unit.

High colour fidelity is another strong suit of the latest Gen-4 Luxeon COB LEDs, which have CRI of up to 90.

Consistent rendering of all wavelengths makes them ideal for colour-critical lighting in areas such as such as retail displays, showrooms, healthcare centres, laboratories, and industrial-inspection areas. Applications like high-bay and low-bay lighting, downlights, spotlights, and architectural or general outdoor lighting can also benefit from the superior brightness, clarity and efficacy of Luxeon Gen-4 LEDs.

All units are hot-tested at 85°C, which gives an accurate indication of performance and reliability in real-world operating conditions and removes additional testing burdens from lighting manufacturers.

The Lumileds Gen-4 Luxeon COB LEDs are shipping now from RS in the EMEA and Asia Pacific regions.
