Light emitter array layout for color mixing

摘要

Solid state lighting components are disclosed having multiple discrete light sources whose light combines to provide the desired emission characteristics. One embodiment of an LED component according to the present invention comprises a rectangular submount. A first group of blue shifted yellow (BSY) LED chips, a second group of BSY LED chips and a group of red LED chips are mounted on the submount. A plurality of contacts is arranged along one of the edges of the submount and accessible from one side of the component for applying electrical signals to the groups of LED chips.

主权项

1. A light emitting diode (LED) component, comprising:
an array of LEDs mounted on a submount comprising a plurality of LEDs wherein a first group of LEDs emits light in a first wavelength range, a second group of LEDs emits light in said first wavelength range, and a third group of LEDs emits light in a second wavelength range, wherein said first group of LEDs are positioned such that parallel surfaces of said first group of LEDs that face each other overlap by less than 50%; and a plurality of contacts that conduct electrical signals to said groups of LEDs, wherein a different electrical signal can be conducted to each group of LEDs and said contacts are along a single edge of said submount; wherein an electrical signal conducted to said first group of LEDs is different from an electrical signal conducted to said second group of LEDs.
