Lens, lens array having same and light source module having same

A lens array comprising a plurality of lenses arranged along a longitudinal axis thereof, each of the plurality of lenses being for coupling with a point light source, each lens comprising:

• a first light incident surface;
• a second light incident surface connected with the first light incident surface, the first and the second light incident surfaces cooperatively defining a receiving space therebetween, the receiving space being configured for accommodating the point light source;
• a reflecting surface connected with the second light emitting surface;
• a first light emitting surface opposite to the first light incident surface, wherein light entering the lens through the first light incident surface exits from the first light emitting surface;
• and
• a second light emitting surface connected between the first light emitting surface and the reflecting surface, wherein light entering the lens through second light incident surface is reflected by the reflecting surface and directed to the second light emitting surface to exit the lens.

A light source module comprising:

• a plurality of point light sources for emitting light;
• a lens array comprising a plurality of lenses arranged along a longitudinal axis thereof, each of the plurality of lenses being for coupling with a corresponding point light source, each lens comprising:
• a first light incident surface;
• a second light incident surface connected with the first light incident surface, the first and the second light incident surfaces cooperatively defining a receiving space therebetween, the receiving space being configured for accommodating the corresponding point light source;
• a reflecting surface connected with the second light emitting surface;
• a first light emitting surface opposite to the first light incident surface, wherein light entering the lens through the first light incident surface exits from the first light emitting surface;
• and
• a second light emitting surface connected between the first light emitting surface and the reflecting surface, wherein light entering the lens through second light incident surface is reflected by the reflecting surface and directed to the second light emitting surface to exit the lens.
