Written by Jason Ford, technical services manager at Osram, it covers topics such as fine binning for homogeneity and general illumination issues.
It begins:
With developments made in the efficacy of white LEDs in the past few years, LED technology is driving the future of lighting.
As white light is the main driver for general illumination, there is a particularly strong focus on improving the efficiency of white LEDs, which currently outperform tungsten halogen lamps with efficacies from 45-55lm.Another "How To" - related to embedded programming - was also recently posted.
