Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
Incorporated by reference to referring to Fig. 1 to Fig. 5, the utility model provides a kind of optics projection lens 1.The optics projection lens
1 material is optical glass or resin.In the present embodiment, the shape of the optics projection lens 1 is generally rectangular
Shape.In other embodiments, it can arbitrarily change the shape of the optics projection lens 1 according to actual needs, for example may be used
To be designed to square, polygon or circle etc..
Projection forms the lens unit 3 of multiple array arrangements in the optics projection lens 1.Two adjacent lens units
Interval between 3 is equal.
Each lens unit 3 includes incidence surface 30 and light-emitting surface 32, free form surface of the incidence surface 30 for indent, light-emitting surface
32 be evagination free form surface, the incidence surface 30 be hemispherical curved surface, the light-emitting surface 32 be spheroid shape curved surface, it is described enter light
The central shaft in face 30 is overlapped with the short axle of the light-emitting surface.The incidence surface 30 of indent forms the mixed light lamp chamber for accommodating light emitting diode
