The paper presents the results of calculations of colorimetric parameters of LED sources operating at a temperature range from -25oC to 25oC. The chromaticity coordinates and color rendition quality parameters were calculated on the basis of registered spectral distributions of radiation. For individual LED chromaticity shift is illustrated at CIE 1931 x,y diagram with 3 step and 7 step MacAdam ellipses. Full Text: PDF ReferencesJ. P. Freyssinier, D. Frering, J. Taylor, N.

Solid-state lighting technology is rapidly gaining acceptance in lighting industry street lighting, traffic lighting, decorative lighting, projection displays, display backlighting, automotive lighting, and so on. Differing from conventional light sources that use tungsten filament, plasma, or gases to generate light, solid-state lighting is based on organic or inorganic light emitting diodes (LEDs), and has the potential to generate light with almost 100 % efficiency. LED luminaires have a long lifetime and are environmentally friendly with no toxic mercury contained. However, the success of these luminaires depends on system design, which comprises an understanding of several factors such as performance and control. In this chapter, we shall touch upon some technological advancements in the field of solid-state lighting technologies and challenges that limit their market penetration for consumer lighting.
