Synchronized light board and heat sink rotation for illumination beam redirection

Abstract

Illustrative embodiments of a light fixture are disclosed that feature a housing and an internal optical module. The optical module includes one or more light emitter assemblies that are rotationally adjustable and a fixed primary heat sink. Each light emitter assembly includes a light emitter member, an intermediate rotatable heat sink, and an optional optic. The primary heat sink within the housing provides thermally conductive surfaces that maintain contact with the intermediate heat sinks throughout their range of rotation with the light emitter members. A synchronization mechanism ensures coordinated rotation of the light emitter assemblies. The fixture may also include a lens that encloses the optical module within the housing and an actuator for adjusting the rotation of the light emitters from outside the housing. The design allows for efficient thermal management and adjustable light beam direction with no change in position of the external housing or the mounting structure.
