Lumileds — LUXEON 5050 Square High-Power LEDs

Lumileds LUXEON 5050 Square High-Power LED

High-power LED housed in robust package for use in exterior applications.

Lumileds has unveiled the LUXEON 5050 Square LED, a multi-die emitter with a square Light Emitting Surface (LES) which provides high flux and efficacy in directional lighting applications.

The LUXEON 5050 Square offers 25% higher flux than the LUXEON 5050 Round emitter. Its efficacy is higher than that of any 5050 package on the market.

The LUXEON 5050 Square also offers superior corrosion resistance, resulting in substantially lower flux degradation and less color shift when used in harsh environments.

Producing higher brightness from a standard 5050 footprint, the high-power LUXEON 5050 Square allows for drop-in replacement in existing systems, or the design of new, more robust fixtures.

Typical flux of the LUXEON 5050 Square 5000K at a drive current of 160mA is 825lm at 170lm/W. High efficacy means that lighting equipment manufacturers can achieve higher system efficiency, or use fewer emitters for a more compact design. The design of compact fixtures is facilitated by the low thermal resistance of the substrate, just 1.4°C/W, enabling the use of a smaller heat-sink.
