Achieving efficiency records with multi-die emitter
Lumileds introduced the LUXEON MX, a multi-die emitter that delivers efficiency and flux for outdoor fixtures and high bay lighting applications. Lighting fixtures benefit from the emitter’s 1,200 lumen, 150 lm/W efficacy, at 85°C which enables a system efficiency of 120 lm/W when driven at 700 mA.
“This is double the flux of comparable emitters in 120 lm/W systems. We’ve achieved this performance leap by optimising the LED for improved efficiency at higher drive currents up to 1.5A with the 12V device,” explained Seth Danielson, product manager for the LUXEON MX.
With these developments, Lumileds has maximised emitter efficiency and lifetime. Most impressively, the LUXEON MX makes it possible for luminaire makers to meet the efficiency and quality requirements of the DesignLights Consortium (DLC) Premium V4.1 at 700mA 85°C.
“By creating products eligible for the DLC Qualified Products List, cities and municipalities can receive rebates on their LED street lighting projects, while also realising the fast return on investment from using the most efficient emitters,” said Danielson.
Furthermore, the LUXEON MX leverages a new, robust package that dramatically increases the projected lumen maintenance compared to the LUXEON M. The LUXEON MX is an instant upgrade to the LUXEON M, featuring identical footprint and optical characteristics.
The LUXEON MX multi-die emitter will be offered in a range of color temperatures (3000K to 6500K) and CRIs (70, 80 and 90) in convenient 3V, 6V and 12V configurations. Applications include roadway lighting, street lighting, stadium lighting and high bay fixtures.
