Illumination apparatus

摘要

An illumination apparatus, a method of manufacture of the same and a heat sink apparatus for use in said illumination apparatus in which an array of optical elements directs light from an array of light emitting elements through a heat dissipating structure to achieve a thin and efficient light source that provides directional illumination with efficient dissipation of generated heat into the illuminated environment.

主权项

1. An illumination apparatus, comprising:
a plurality of light emitting elements positioned on a first surface of a substrate and arranged in an array; a plurality of catadioptric optical elements that are arranged in an array, the array of catadioptric optical elements being aligned with the array of light emitting elements such that individual optical elements are aligned with respective individual light emitting elements; a heat dissipating structure positioned on the first surface of the substrate; the heat dissipating structure thermally coupled to the light emitting elements at least to an extent via the substrate such that in operation heat from the light emitting elements is dissipated by the heat dissipating structure; wherein at least some different portions of the heat dissipating structure are interspersed between at least some different light emitting elements of the array of light emitting elements; wherein the heat dissipating structure comprises a thermally conducting plate that is thermally coupled to the first surface of the substrate.
