Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] see Figure 1 to Figure 3 , The light source module 100 provided by the embodiment of the present invention includes a light source 10 and a lens 20 . The light source 10 can be one of light emitting diodes, discharge lamps and halogen lamps. The light source module 100 can be used in products such as car lamps.

[0026] The lens 20 includes a light incident surface 21 , a first light exit surface 22 , a second light exit surface 23 , a third light exit surface 24 and a connection surface 25 connecting the first light exit surface 22 and the third light exit surface 24 . The first light exit surface 22 , the second light exit surface 23 and the third light exit surface 24 are opposite to the light incident surface 21 .

[0027] The light incident surface 21 can be convex, concave or flat. In this embodiment, the light incident surface 21 is a plane...

Abstract

The invention relates to a lens. The lens comprises a light incident surface and a first light emitting surface, wherein the first light emitting surface is a convex surface and is opposite to the light incident surface; the first light emitting surface and the light incident surface form a convex lens part; the first light emitting surface is provided with a first side; the lens also comprises asecond light emitting surface which is positioned on one side of the first side of the first light emitting surface; the second light emitting surface is an convex surface; and the included angle between any tangent plane on the second light emitting surface and the plane vertical to an optical axis of the convex lens part is larger than that between any tangent plane passing through any point ofthe first side of the first light emitting surface and the plane vertical to the optical axis. The invention also relates to a light source module with the lens.

Description

technical field [0001] The invention relates to the field of optics, in particular to a lens and a light source module with the lens. Background technique [0002] At present, most light sources, such as light-emitting diodes, discharge lamps, and halogen lamps, etc., have a large divergence angle of outgoing light. To achieve long-distance lighting, it is generally necessary to install a focusing lens in front of these light sources to reduce the divergence of the light. Divergence angle, so that its light is concentrated near the optical axis of the focusing lens and exits. However, in some products, such as car lights, the effective light emitted by the light source is the light that irradiates the ground, the front and both sides of the front. , there is no use value, therefore, for this kind of light, the less the better. Contents of the invention [0003] In view of this, it is necessary to provide a lens capable of better controlling the direction of light emitted...
