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 a rear annular face, the rear annular face having a cavity formed therein;

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;

a light emitting element disposed in the cavity; and

a reflective cover covering a portion of the front annular face corresponding to the cavity, whereby light emitted from the light-emitting element is reflected by the reflective cover into the light guiding ring for providing a substantially uniform light transmission through said light-guiding ring.
