  • Patent number: 10060590
    Abstract: This invention is related to an improved light ring structure for vehicle lamp. An incident portion is extended and projected from one side of a light-guiding ring, and a V-shaped light-guiding portion connects the incident portion and the light-guiding ring. An optical structure is formed on an optical surface of the light-guiding ring, and several teeth are aligned on the optical surface. One side of each tooth is a vertical section which faces to the incident portion and the other side of that is an inclined section. The width of the teeth is increased gradually from the incident portion and the opposite of the incident portion to the two sides of the light-guiding ring, forming the widest tooth at the two sides of the light-guiding ring, and the height of the teeth is increased gradually from the incident portion, forming the highest tooth at the opposite of the incident portion.
