Preferably, described lens-shape is polymorphic structure; Described polymorphic structure is combined by a cylindrical structural body and a truncated cone-shaped structure; The large bottom surface of described truncated cone-shaped structure is connected with the end face of cylindrical structural body, and the large bottom surface diameter of truncated cone-shaped structure is identical with the diameter of cylindrical structural body; The outer face of cylindrical structural body forms the upper surface of lens, and the handle face of truncated cone-shaped structure forms the lower surface of lens; On the lower surface of described lens, be provided with blind hole, the orifice diameter of described blind hole is greater than diameter at the bottom of hole, seamlessly transits between at the bottom of aperture and hole by taper seat; It at the bottom of the hole of blind hole, is the sphere of evagination; On the upper surface of described lens, be provided with many grooves, many grooves axially parallel to each other; Many groove spaced sets, the cambered surface by evagination between adjacent two grooves seamlessly transits; The cross section of groove is the circular arc of indent.Adopt after aforementioned improved, through the refraction action of lens, light is comparatively concentrated and be there is no an obvious speck,

In order further to improve bonding strength, the utility model has also proposed following preferred constructive form for support and lens: the junction of described cylindrical structural body and truncated cone-shaped structure is provided with the spacing ring of evagination; On described support, be provided with the mounting groove mating with lens, mounting groove middle part is provided with clamping projection and the limiting stand terrace mating with spacing ring; Described spacing ring is between clamping projection and limiting stand terrace.During assembling, first lens are inserted in mounting groove, then by extruding, the spacing ring on lens is snapped between clamping projection and limiting stand terrace, this connected mode is simple in structure, easy for installation, cannot dismantle, and connective stability is fine.

For fear of lens, rotate freely, the utility model has also been done following improvement: the structure surface of described spacing ring below is provided with square projection; The upper surface of described limiting stand terrace is provided with square breach.After lens are in place, square projection is connected in square breach, can avoid lens to rotate freely, and further improves structural stability.

Inventor has also proposed following preferred version for the syndeton between support and LED circuit plate: on the outer wall of described support, be provided with a plurality of journal stirrups, be provided with connecting screw hole on journal stirrup, journal stirrup lower surface is provided with positioning convex; On the upper surface of described LED circuit plate, be provided with locating hole and connecting hole, described locating hole mates with positioning convex, and described connecting hole mates with connecting screw hole, between connecting hole and connecting screw hole, is screwed.After adopting this to improve, can to support and LED circuit plate, position easily when mounted, meanwhile, after installing, the lateral stress that structure bears can improve the uniformity of structure stress by support and LED circuit plate shared, guarantees structural strength.

Useful technique effect of the present utility model is: simple in structure, intensity is high, the loss of the light that LED sends is less.
