Abstract
A light module includes a light source and an optical lens. The light source emits light to the optical lens. The light source is a single unit and has a parallelizing surface, a first plane, a wave surface, and a second plane in sequence. The light source emits light to the optical lens and through the parallelizing surface, the first plane, the wave surface, and the second plane in sequence to form a parallel linear light.
Claims9
A light module, comprising:
- a light source for emitting light from a light side to an object side;
- and
- an optical lens, which is a single unit, having a parallelizing surface, a first plane, a wave surface, and a second plane from the light side to said object side and where the optical lens has a cavity at a center to form the first plane and the wave surface at opposite sidewalls of the cavity and;
- wherein the light from the light source enters the optical lens via the parallelizing surface and leaves the optical lens via the first plane, and then the light enters said optical lens again via the wave surface and leaves the optical lens via the second plane.
An optical lens, which is a single unit, comprising a parallelizing surface, a first plane, a wave surface, and a second plane in sequence, wherein the light enters the optical lens via the parallelizing surface and leaves the optical lens via the first plane, and then the light enters optical lens again via the wave surface and leaves the optical lens via the second plane and where the optical lens has a cavity at a center to form the first plane and the wave surface at opposite sidewalls of the cavity.
