The recessed lower limit in vertex, three faces around vertex are aspheric, make it have three light-emitting surfaces.
Preferred embodiment on the basis of said program and as said program：The lens body is tetrapyamid shape,
The recessed lower limit in vertex, four faces around vertex are aspheric, make it have four light-emitting surfaces.
Preferred embodiment on the basis of said program and as said program：The lens body is pentagonal pyramid shape,
The recessed lower limit in vertex, five faces around vertex are aspheric, make it have five light-emitting surfaces.
Preferred embodiment on the basis of said program and as said program：The lens body is hexagonal pyramid shape,
The recessed lower limit in vertex, six faces around vertex are aspheric, make it have six light-emitting surfaces.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：
1. free form surface there are one, facilitates mold to process, processing cost is reduced.
2. lens compare relatively thin, be conducive to be combined into one with the dust cover of lamp lens, reduce lamps and lanterns cost
3. lens compare relatively thin, be conducive to the slim appearance design of lamps and lanterns.
4. this lens significantly, can effectively be such that the light that LED is sent out is diffused according to using needs.
5. uniform hot spot may be implemented, light and shade changes sharp keen hot spot.
6. by change lens surface structure may be implemented a variety of hot spot effects (such as triangle hot spot, square focus spot, five
Side shape, hexagon hot spot).
