This presentation provides a summary of the safety, performance, and general construction requirements that are included in street-light specifications today.
To conclude our series of articles on LED photobiological safety, LESLIE LYONS puts IEC62471 to work in consideration of the hazards posed by today’s LEDs and LED-based products...
MR16 sockets present a significant retrofit-lamp opportunity for LEDs, explains KAMAL NAJMI, but installed transformers complicate the design of a drop-in SSL replacement.
Relative to visible LEDs, UV LEDs are a quiet market at only $30 million, yet recent breakthroughs in radiant power and intensity have enabled the displacement of mercury-vapor...
The latest LEDs can reliably operate at drive currents well above binning currents, delivering more lumens and robust luminaire life while lowering system cost, explain DAVID ...
Secondary optics using total internal reflection perform better than reflector-based optics for constructing directional LED-based modules, but only if the light-distribution ...
Lighting companies are moving forward with adaptive-control technology that can save significant energy especially when combined with inherently-efficient LED sources, explains...
Requirements for LED processing equipment are changing from cost driven to more technology driven decisions, a clear trend to more complex and more efficient manufacturing, according...
Work on a new and improved measure of color-rendering quality has apparently stagnated in the CIE, and the failure leaves the broad lighting community without a tool that would...
A ceremony has been held to mark the first phase of a project to install LED exterior lighting at one of Europe’s great art museums, writes TIM WHITAKER.
Now that procedures are in place to make long-term lumen-maintenance projections for LED components, efforts are being made to develop methods for testing the lighting system ...
A Green Paper on LED- and OLED-based lighting published by the European Commission launches a period of public consultation on the future development of SSL in Europe, as TIM ...
