Abstract

An illumination assembly includes a first diode row having first and second multi-chip LED units, and a second diode row having third and fourth multi-chip LED units. The first through fourth multi-chip LED units each includes red, green, and blue LEDs. Light of the red, green, and blue LEDs of the first through fourth multi-chip LED units has a respective primary emission direction (PED). The PEDs of same colored ones of the LEDs of the first and second multi-chip LED units are oriented along one direction. The PEDs of the remaining two LEDs of the first and second multi-chip LED units are oriented in opposite directions from each other. The PEDs of the LEDs of the third and fourth multi-chip LED units are oriented in opposite directions as compared to those of the LEDs of the first and second multi-chip LED units, respectively.
