Lumileds claims highest LED efficacy with new 5050 package

The Luxeon 5050 Square LES (Light Emitting Surface) from Lumileds is a square, multi-die emitter said to deliver industry-leading flux and efficacy for directional lighting applications.

The Luxeon 5050 Square builds on the legacy of the Luxeon 5050 Round emitter as the go-to solution for streetlights and downlights, while boosting flux by 25% and delivering the highest efficacy of any 5050 package on the market.

The new device is also outperforming competing modules in corrosion resistance testing, enabling significantly lower flux degradation and less color shift when used in harsh environments. “The Luxeon 5050’s EMC (Epoxy Molding Compound) package demonstrates corrosion resistance that is comparable to a ceramic package. Standard industry testing in a sulfur environment also shows the Luxeon 5050 Square demonstrated significantly less flux loss and color shift than competing 5050 size emitters. This enables a much more robust design in the end application” explained Mei Yi, Product Manager for the Luxeon 5050 LED line. Typical flux of the Luxeon 5050 Square is 825 lumens at 170 lm/W when a 5000K 70CRI emitter is driven nominally at 160mA. The top notch efficacy in the industry translates to more efficient fixtures or the use of fewer emitters for a more compact design. Fixture size is further reduced by the emitter’s low thermal resistance substrate (1.4°C/W), which reduces heatsink requirements. The LED is initially offered in a color temperature range of 2200K-6500K at a minimum CRI of 70 in voltage options of 6V and 30V.
