Along with the development of semiconductor illumination technique, the light efficiency of light emitting diode (Lightemittingdiode, LED) improves constantly, and now just progressively replaces conventional light source.For LED light source, the luminous energy how effectively distribution LED sends is the key issue that in this LED light source, Optical System Design will solve.Current LED light source lens are difficult to realize high section light formula class rectangular light spot, are the illumination providing human nature comfortable, need the light sent by LED light source to carry out science adjustment.
Utility model content
The utility model aims to provide a kind of height applying LED illumination and cuts light formula class rectangular light spot lens element, structure is simple, the light that can send light fixture LED light source carries out being totally reflected and processes with reflecting, and reaches obvious dead line and uniform light spots, and substantially increases the utilization rate of light.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of height applying LED illumination disclosed in the utility model cuts light formula class rectangular light spot lens element, comprise lens body, the profile of described lens body is tubaeform, lens body bottom surface central authorities offer groove C, groove C is truncated cone-shaped, bottom surface is small end, lens body end face central authorities offer groove A, groove A bottom surface central authorities offer groove B, described groove A cross section is rectangle, groove A oral area cross-sectional area is greater than bottom transverse area of section, and described groove B cross section is circular, and groove B oral area cross-sectional area is greater than bottom transverse area of section.
Further, the bottom surface of described groove C is plane or free form surface, and the side of groove C is curved surface.
Further, the bottom surface of described groove A is recessed curved surface, and described groove B bottom surface is the sphere of evagination.
Further, shown lens body end face is the combination of multiple free form surface.
Further, described lens body end face comprises first surface, the second curved surface and stupefied, and described first surface is the arc-shaped surface of evagination, and described second curved surface is for being waveform face.
Further, described lens body top edge is ring plain.
Further, described lens body lateral surface is fully reflecting surface.
Further, described lens body top is provided with outside flange.
The utility model has following beneficial effect:
