Abstract

A light with a ring structure for a vehicle lamp has a light-guiding ring with a dull face, a light-emitting element, and a reflective cover. The light-guiding ring defines a front annular face and has a cavity. The light-emitting element is disposed in the cavity. The reflective cover is disposed on a part of the front annular face and corresponds to the cavity. The light-guiding ring with a dull face guides light emitted by the light-emitting element therein. The reflective cover reflects the light into the light-guiding ring. As such, the brightness of the light with a ring structure is even to improve the warning function of a vehicle lamp to ensure a safer driving experience for its user.

Claims

1. A light with a ring structure for a vehicle lamp, comprising:

a light-guiding ring with a dull face, the light-guiding ring defining a front annular face and having a cavity;

a light-emitting element disposed in the cavity; and

a reflective cover disposed on a part of the front annular face and corresponding to the cavity.

2. The light with a ring structure as claimed in claim 1, wherein the light-guiding ring defines a rear annular face, and the cavity is formed in the rear annular face.

3. The light with a ring structure as claimed in claim 2, wherein the rear annular face of the light-guiding ring has two positioning posts disposed on two opposite sides thereof, respectively.

4. The light with a ring structure as claimed in claim 2, wherein the rear annular face of the light-guiding ring has two protrusions disposed on two outer sides of the cavity, respectively.

5. The light with a ring structure as claimed in claim 1, wherein the light-emitting element is an LED.

6. The light with a ring structure as claimed in claim 1, wherein the light-emitting element has a quantity of two, and the light-emitting elements face two ends of the cavity, respectively.

7. The light with a ring structure as claimed in claim 1, wherein the front annular face of the light-guiding ring has a cambered surface, and the reflective cover has a cambered shape and hooks onto the light-guiding ring.

8. The light with a ring structure as claimed in claim 1, comprising a circuit board, wherein the circuit board is disposed in the cavity, and the light-emitting element is electrically connected to the circuit board.
