Abstract
Color uniformity is an important performance metric for many solid-state lighting systems, particularly those systems that use multiple light-emitting diodes (LEDs) to produce the desired illumination distribution. Once the optical design is done, however, it is important to understand how the color uniformity changes when LEDs from within a single color-bin are mixed. Can the design tolerate any LED within the color-bin? Are the inter-bin color variations noticeable in the beam distribution? Are they noticeable when looking back at the luminaire? This paper looks at this question using an exterior automotive stop lamp. The statistical variation of color uniformity is analyzed using assumed interbin statistical variation for the color of the LEDs.
