[0006] To achieve the above object, the utility model provides the following technical scheme: a kind of lens that avoids deviation, including lens body, the lens body is semicircular convex structure, and recessed area is equipped at lens body convex top end, and lamp pearl avoids empty hole is equipped in the middle of lens body, and lamp pearl avoids empty hole opening end is equipped with limit slot.

[0007] Further, the lamp pearl avoids empty hole inside is embedded with lamp pearl body, and lamp pearl body is limited with limit slot.

[0008] Further, the lamp pearl body is middle power patch super-bright light emitting diode, and the center of lamp pearl body is above the axis of lens body.

[0009] Further, the limit slot outer edge is provided with grid pattern recess, and the outer edge of grid pattern recess is provided with glue ring.

[0010] Further, the lens body bottom is composed of outer glue ring, grid pattern recess in middle part and lamp pearl avoids empty hole inside from outside to inside.

[0011] Further, the back of lens body is bonded with aluminum substrate, and the aluminum substrate is provided with glue pouring area between aluminum substrate and lens body.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model discloses a convex top end of lens body is equipped with the concave area, makes the light spot that emits from the light source more even soft, under the condition that the arrangement and OD of lamp pearl body are same, the light spot and the light spot link more even, the whole edition evenness is higher than the lens of prior art without concave area design, on the other hand, the lens body itself is equipped with the limit card slot, can effectively solve the problem of installing deviation.
