Lumileds claims Efficiency record with Multi-die Emitter
Lumileds has introduced the Luxeon MX, a multi-die emitter that is claimed to deliver industry leading 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 85degC which enables a system efficiency of 120 lm/W when driven at 700mA.
"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 says it has maximised emitter efficiency and lifetime. 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 85degC.
"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.Â
Furthermore, the Luxeon MX uses a new, robust package that 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 colour 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.
