Abstract
The present disclosure discloses a lens, a light source module and a lighting device. The lens includes a bottom surface, an inner surface, an outer surface, and a first accommodating chamber configured for accommodating a light-emitting assembly, a wall face of the first accommodating chamber being an inner surface of the lens; where, the inner surface has a sawtooth shape, and a first light incident surface, a second light incident surface and a third light incident surface, the outer surface includes a first light-emitting surface, a second light-emitting surface and a third light-emitting surface.
Claims20
A lens, comprising:
- a bottom surface, an inner surface, an outer surface, and a first accommodating chamber configured for accommodating a light-emitting assembly, a wall face of the first accommodating chamber being the inner surface of the lens, and the lens having an axisymmetric structure;
- wherein:
- the inner surface comprises a sawtooth-shaped cross-section a first light incident surface protruding toward the first accommodating chamber and at least two pairs of tooth corners extending into the first accommodating chamber;
- a first pair of tooth corners comprise second light incident surfaces provided opposite to each other;
- and a second pair of tooth corners comprise third light incident surfaces provided opposite to each other;
- the outer surface comprises two first light-emitting surfaces located at a middle top region and opposite to each other, second light-emitting surfaces located on two sides of the two first light-emitting surfaces and intersecting with adjacent first light-emitting surfaces, and a third light-emitting surface extending from the second light-emitting surface to the bottom surface, wherein the two first light-emitting surfaces constitute a V-shaped structure, and the third light-emitting surface is a curved surface protruding away from the first accommodating chamber.
A light source module, comprising:
- a lens and a light-emitting assembly comprising a light source board, and a light emitting unit located on the light source board, wherein the lens comprises:
- a bottom surface, an inner surface, an outer surface, and a first accommodating chamber configured for accommodating a light-emitting assembly, a wall face of the first accommodating chamber being the inner surface of the lens, and the lens having an axisymmetric structure;
- wherein:
- the inner surface comprises a sawtooth-shaped cross-section a first light incident surface protruding toward the first accommodating chamber and at least two pairs of tooth corners extending into the first accommodating chamber;
- a first pair of tooth corners comprise second light incident surfaces provided opposite to each other;
- and a second pair of tooth corners comprise third light incident surfaces provided opposite to each other;
- the outer surface comprises two first light-emitting surfaces located at a middle top region and opposite to each other, second light-emitting surfaces located on two sides of the two first light-emitting surfaces and intersecting with adjacent first light-emitting surfaces, and a third light-emitting surface extending from the second light-emitting surface to the bottom surface, wherein the two first light-emitting surfaces constitute a V-shaped structure, and the third light-emitting surface is a curved surface protruding away from the first accommodating chamber.
