A Guide to Specifying LEDs
PhotonStar™ supports and provides data in accordance with 'The Guide for Specifying LED lighting' produced by the Lighting Industry Liaison Group (LILG) consisting of the organisations below:
Also many of the requirements are being mirrored in the International Electrotechnical Commission, IEC LED Modules for General Lighting Performance Requirements IEC/PAS 62717, and particular requirements for LED luminaires IEC/PAS 62722
A Chain is only as strong as the weakest link
An LED luminaire is in many ways more complex than a traditional lighting fixture, in that many system components and operating conditions require tighter control to provide optimum performance. It is an electromechanical system that includes, in addition to the essential light emitting source, provisions for heat transfer, electrical control, optical conditioning, mechanical support, and protection, as well as aesthetic design elements. Because the LEDs themselves are expected to have long life, all of these other components, adhesives, and other materials must be equally long lived, or, to the extent they are not, they will limit the system lifetime.
