Lens structure for a vehicular lamp

A lens structure for a vehicular lamp comprising:

• an incident portion, with the incident portion being annular and surrounding a central axis, with the incident portion including a first inner annular face and a first outer annular face spaced from the first inner annular face in a radial direction perpendicular to the central axis, with the incident portion further including an incident face behind the first inner annular face and the first outer annular face, and with the incident face being plane;
• a light mixing portion located in front of the incident portion, with the light mixing portion including a front end and a rear end spaced from the front end along the central axis, with the rear end of the light mixing portion connected to a front end of the incident portion, with the light mixing portion extending outward from the rear end thereof towards the front end thereof in the radial direction perpendicular to the central axis, with the light mixing portion further including a first reflective face on an inner side thereof and a second reflective face on an outer side thereof spaced from the first reflective face in the radial direction, and with the second reflective face having a plurality of continuous toothed faces;
• and
• a light output portion located in front of the light mixing portion, with the light output portion including a rear end and a front end spaced from the rear end of the light output portion along the central axis, with the rear end of the light output portion connected to the front end of the light mixing portion, with the front end of the light output portion including a light output face, with most part of light rays from a light source adapted to directly enter the lens structure via the incident face of the incident portion, adapted to be reflected by the first reflective face to the second reflective face, adapted to be reflected by the second reflective face to the first reflective face, and adapted to be emitted via the light output face of the light output portion after a plurality of times of reflection, splitting, and mixing of the light rays.
