InGaN’s light intensity not from clustering

  The full potential of LEDs remains limited because of the mysteries about the exact light-emission mechanism in the semiconducting materials. One controversy surrounds the reason for the high-intensity light output from indium gallium nitride (InGaN). Researchers have been split on whether or not indium-rich clusters form within the material and provide LEDs’ remarkable efficiency. […]

Colour temperature contrast in a single lamp

  Drawing on this extensive experience of light source colour quality engineering, Philips says it has now perfected a new optimised light spectrum for LED light sources which gives a new colour experience, similar to the CDM Elite lamp. This new solution embraces a combination of clean, crisp white light with deep, rich colours within […]
