Title: Configurable luminaire with light sources variably oriented with respect to an array of concave mirrors

Abstract

An array of LEDs is supported by a support mechanism that both supports conductors leading to the LEDs and sinks heat from the LEDs. The support mechanism may be a transparent heat-conducting sheet or an array of cantilevered arms at different angles that support the LEDs and sink heat. This reduces the blockage of light. The LEDs are positioned generally in the focal plane of an array of concave mirrors that collimate the light. The LEDs and array of mirrors are translatable with respect to one another to steer the aggregate light beam to customize the emission. The LEDs may be variably oriented with respect to the associated mirror apertures so as to create different light beams emitted from different ones of the mirrors.
