Abstract
An optical element includes a first light entrance surface, a second light entrance surface, a third light entrance surface, a first light exit surface, a second light exit surface, a first reflective surface, a third light exit surface, a second reflective surface and a third reflective surface. By the relative arrangement between the first light entrance surface, the second light entrance surface, the third light entrance surface, the first light exit surface, the second light exit surface, the first reflective surface, the third light exit surface, the second reflective surface and the third reflective surface, the optical element can have the characteristics of high light intensity and miniaturization.
Claims19
An optical element comprising:
- a first light entrance surface;
- a second light entrance surface adjacent to the first light entrance surface;
- a third light entrance surface adjacent to the second light entrance surface;
- a first light exit surface arranged relative to the first light entrance surface;
- a second light exit surface adjacent to the first light exit surface;
- a first reflective surface adjacent to the second light exit surface;
- a third light exit surface adjacent to the first reflective surface;
- a second reflective surface adjacent to the third light exit surface;
- and
- a third reflective surface adjacent to the second reflective surface and the third light entrance surface;
- wherein a first portion of a light sequentially passes through the first light entrance surface and the first light exit surface to travel out of the optical element;
- a second portion of the light sequentially passes through the second light entrance surface, is reflected by the first reflective surface, and passes through the second light exit surface) to travel out of the optical element;
- a third portion of the light sequentially passes through the third light entrance surface, is reflected by the third reflective surface, is reflected by the second reflective surface, and passes through the third light exit surface to travel out of the optical element.
A warning light comprising:
- a casing;
- a heat dissipation plate disposed in the casing;
- a circuit board disposed in the casing and stacked on the heat dissipation plate;
- a plurality of light sources disposed on the circuit board at intervals;
- and
- an optical element disposed in the casing and stacked on the circuit board, a light emitted by each of the plurality of light sources traveling out of the optical element;
- wherein the casing and the optical element are flexible.
