Optical attachment features for light-emitting diode-based lighting system

摘要

An optical attachment feature of a light-emitting diode (LED) lighting system includes an enclosure, a trim, a reflector, and a diffuser. The enclosure can include an enclosure wall forming a cavity and an enclosure collar having a first profile. The trim can include a trim collar that abuts to the enclosure collar, wherein the trim collar has a second profile. The reflector can include an outer surface, an inner surface having reflective material disposed thereon, and a reflector collar having a first optical attachment mechanism. The diffuser can include a diffuser collar, where the diffuser collar can include a second optical attachment mechanism and a third optical attachment mechanism, where the second optical attachment mechanism can couple to the first optical attachment mechanism, and where the third optical attachment mechanism is disposed within a feature formed by the first profile and the second profile when the enclosure collar is mechanically coupled to the trim collar.

主权项

1. A light-emitting diode (LED) lighting system, comprising:
an enclosure comprising an enclosure wall forming a cavity and an enclosure collar having a first profile, wherein the first profile comprises a recess; a trim comprising a trim collar that directly abuts the enclosure collar, wherein the trim collar has a second profile, wherein the second profile comprises an outer surface; a reflector comprising an outer surface, an inner surface comprises a reflective material, and a reflector collar having a first optical attachment mechanism; and a diffuser comprising a diffuser collar, wherein the diffuser collar comprises a second optical attachment mechanism and a third optical attachment mechanism positioned adjacent to the second optical attachment mechanism, wherein the second optical attachment mechanism couples to the first optical attachment mechanism, wherein the third optical attachment mechanism is a protrusion, and wherein the protrusion is disposed within the recess of the first profile of the enclosure collar and directly abuts the outer surface of the second profile of the trim collar when the enclosure collar is mechanically coupled to the trim collar, wherein the reflector further comprises a fourth optical attachment mechanism disposed on the reflector collar, wherein the diffuser further comprises a fifth optical attachment mechanism disposed on the diffuser collar, wherein the fourth optical attachment mechanism is detachably coupled to the fifth optical attachment mechanism when the diffuser collar directly abuts against the reflector collar.
