The U.S. government has finally passed the Energy Policy Act of 2005, which will provide significant levels of funding for the development of white LED lighting technology.
LED light sources are being used more frequently in large-scale applications, but planning them can be hampered by poor color rendering on computer screens.
Drivers based around microcontrollers can be simple to design and offer a number of advantages for controlling high-intensity LEDs. However, some limitations remain, as Pedro ...
A study of dimming methods indicates that the lowest chromaticity shift among high-power white LEDs is observed for phosphor-converted LEDs dimmed using pulse-width modulation...
Multi-watt class LED array light engines are emerging as viable replacements for current light sources. As Gareth Jones of Enfis describes, this brings new opportunities for application...
General illumination, white LEDs and pulse-width modulation were among the subjects discussed during the Fifth International Conference on Solid State Lighting, writes David Nicol...
