Patent number: 7976187Abstract: Light emitting device multi-chip lighting fixtures are disclosed. According to one aspect, a lighting fixture is provided, the lighting fixture having a plurality of light-emitting devices operable for emitting light onto a light diffuser. Where each of the light-emitting devices produces light having a non-uniform luminous intensity, each of the light-emitting devices is positioned with respect to one another to illuminate the surface of the light diffuser with an aggregate light having a substantially uniform luminous intensity. In this way, the light cast by the lighting fixture appears to have a substantially uniform luminous intensity.Type: GrantFiled: March 27, 2008Date of Patent: July 12, 2011Assignee: Cree, Inc.Inventor: Russell G.
