Abstract

A vehicle signal light includes a housing, a light-guiding unit, a light-emitting unit, and a light shield. The housing has a rear wall and a transparent front wall. The light-guiding unit is mounted in the housing, and includes a light-transmitting member and a refractive member. The light-transmitting member has front, rear, and first and second side surfaces. The refractive member includes first protrusions formed on the rear surface. The light-transmitting member and the refractive member are made of a light-transmissive material. The light-emitting unit is disposed proximate to the first and second side surfaces of the light-transmitting member, and emits light into the light-transmitting member. The light shield is disposed adjacent to the rear surface and reflects light emitted thereon toward the housing front wall.

Claims

1. A vehicle signal light, comprising:

a housing having a rear wall and a transparent front wall;

a light-guiding unit mounted in said housing, and including

a light-transmitting member having a front surface adjacent to said front wall, a rear surface opposite to said front surface, and first and second side surfaces each interconnecting said front and rear surfaces, and

a refractive member disposed on said rear surface of said light-transmitting member, said refractive member including a plurality of first protrusions formed on said rear surface,

said light-transmitting member and said refractive member being made of a light-transmissive material;

a light-emitting unit disposed in said housing proximate to at least one of said first and second side surfaces of said light-transmitting member, said light-emitting unit emitting light into said light-transmitting member; and

a light shield disposed in said housing adjacent to said rear surface of said light-transmitting member, said light shield reflecting light emitted thereon toward said front wall of said housing.

2. The vehicle signal light of claim 1, wherein said refractive member of said light-guiding unit is formed as a single piece with said light-transmitting member.

3. The vehicle signal light of claim 1, wherein said light-emitting unit includes a pair of light-emitting diodes disposed respectively proximate to said first and second side surfaces of said light-transmitting member.

4. The vehicle signal light of claim 1, wherein said light shield has a reflective surface adjacent to said rear surface of said light-transmitting member, said light shield including a plurality of second protrusions formed on said reflective surface.

5. The vehicle signal light of claim 1, wherein said light shield includes a pair of auxiliary light-shielding elements disposed respectively adjacent to said first and second side surfaces of said light-transmitting member.

6. The vehicle signal light of claim 1, wherein each of said light-transmitting member and said refractive member is made from one of a polycarbonate (PC) material and a polymethyl methacrylate (PMMA) material.
