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.
