Title:
ビーム整形構造を有する発光アセンブリ
Document Type and Number:
Japanese Patent JP6505326
Kind Code:
B2
Abstract:
A light emitting assembly comprising: a light emitting structure with a first light emission surface comprising one or more point-like light sources to emit light; a transparent beam shaping structure comprising a second light emission surface and a second light receiving surface, wherein the second light receiving surface is arranged at a distance above the first light emission surface to create an air gap to receive light emitted from the light emitting structure within an acceptance angle δ for the beam shaping structure to shape a resulting beam of light being emitted through the second light emission surface; and one or more transparent light guiding elements arranged between the beam shaping structure and the light emitting structure suitably shaped to refract at least part of the light emitted from the first light emission surface under an emergent angle ε larger than the acceptance angle δ towards the beam shaping structure.
