Abstract

The invention herein comprises a linear lighting system which incorporates light emitting diode (LED) light sources with one or more distinct colors including broad band white light. The LED die or die arrays are mounted to a high thermal conductivity circuit board comprising COB technology which can include both the LED die and electronic drive components resulting in a more compact and reliable design with improved thermal and optical performance at lower cost. In conjunction with high efficiency imaging collection optics and aberration corrected cylindrical optics, the output of the LED sources are imaged to a bright line suitable for use in machine vision applications and the like.
