Abstract

Solid state lighting is becoming the preferred choice for many lighting applications that require homogeneous illumination distribution. Light-emitting-diode (LED) sources for lighting are usually composed of several individual LEDs. Nevertheless, packaging density of LED arrays is limited by cost, available space, and particularly by thermal problems. This paper presents an investigation of the effects on illumination uniformity of light sources consisting of multiple LEDs due to different array configurations and packaging density of LEDs. The performance of various array configurations is analyzed using a radiometric analysis and experimental results.
