Abstract

A vehicle lamp apparatus includes a mounting seat, a light transmissive unit, a reflective unit and a light emitting unit. The light transmissive unit is mounted to the mounting seat and includes a partially reflective member disposed to face the mounting seat. The reflective unit is disposed opposite to the partially reflective member and includes a plurality of reflective ridges protruding toward the partially reflective member. The light emitting unit is configured to emit light that is reflected to and fro between the partially reflective member and the reflective ridges so as to generate a light beam refracted by and passing through the light transmissive unit with a particular visual effect.

Claims

1. A vehicle lamp apparatus comprising:

a mounting seat;

a light transmissive unit including

a main body mounted to and cooperating with said mounting seat to define a receiving space therebetween, and

a partially reflective member disposed on said main body within said receiving space and facing said mounting seat;

a reflective unit disposed in said receiving space, opposite to said partially reflective member in a first direction, and including a main portion and a plurality of reflective ridges that protrude from said main portion toward said partially reflective member in the first direction, that extend in a second direction perpendicular to the first direction, and that are spaced apart from one another in a third direction perpendicular to the first and second directions; and

a light emitting unit disposed in said receiving space, and configured to emit light that is reflected to and fro between said partially reflective member and said reflective ridges so as to generate a light beam refracted by and passing through said light transmissive unit.

2. The vehicle lamp apparatus as claimed in claim 1, wherein said main body of said light transmissive unit includes a coupling portion coupled to said mounting seat, and a cover portion connected to one end of said coupling portion opposite to said mounting seat.

3. The vehicle lamp apparatus as claimed in claim 2, wherein said main body of said light transmissive unit further includes a plurality of protrusions protruding from said cover portion toward said reflective unit in the first direction, extending in the second direction, and spaced apart from one another in the third direction, and said partially reflective member is coated on said protrusions.

4. The vehicle lamp apparatus as claimed in claim 1, wherein said light emitting unit includes a plurality of light emitting members spaced apart from one another in the second direction.

5. The vehicle lamp apparatus as claimed in claim 1, wherein said partially reflective member is one of an aluminum coating and a chromium coating.

6. The vehicle lamp apparatus as claimed in claim 1, wherein said reflective ridges are coated with a reflective layer, which is one of an aluminum coating and a chromium coating.
