Abstract

A vehicle anti-collision light is disclosed. In one or more embodiments, the vehicle anti-collision light includes one or more illumination sources disposed on a substrate, and a reflector assembly coupled to the substrate at a base. In embodiments, the reflector assembly includes a reflective element including one or more reflective surfaces configured to redirect a first portion of illumination, and one or more transmissive portions configured to transmit a second portion of illumination through the reflective element. In embodiments, the one or more transmissive portions are bounded within the one or more reflective surfaces of the reflective element such that the reflective element includes one or more reflective surfaces between the base and the one or more transmissive portions, and one or more reflective surfaces between the one or more transmissive portions and a distal edge of the reflective element.

Dependent claims

A vehicle anti-collision light comprising:

one or more illumination sources disposed on a substrate;
a reflector assembly coupled to the substrate at a base, the reflector assembly comprising:
a reflective element including one or more reflective surfaces configured to redirect a first portion of illumination;
and
one or more transmissive portions configured to transmit a second portion of illumination through the reflective element, wherein the one or more transmissive portions comprise at least one of an aperture, a transparent material, or a lens,
wherein the one or more transmissive portions are bounded within the one or more reflective surfaces of the reflective element such that the reflective element includes one or more reflective surfaces between the base and the one or more transmissive portions, and one or more reflective surfaces between the one or more transmissive portions and a distal edge of the reflective element, the reflective element is configured to redirect the first portion of illumination across a first set of vertical angles relative to a substrate plane,
wherein the one or more transmissive portions are configured to transmit a second portion of illumination across a second set of vertical angles relative to the substrate plane, at least one angle of the second set of vertical angles is greater than the first set of vertical angles, the one or more transmissive portions include horizontal transmissive slits which are disposed within the reflective element such that the horizontal transmissive slits are oriented parallel to the substrate plane, the one or more transmissive portions result in a discontinuous reflective element where a top portion and a bottom portion of the reflective element are coupled together via one or more connecting portions.
