Compared with the prior art, the technical scheme has the following beneficial effects:

through the cooperation of first reflecting surface and luminous aperture lateral wall face, reflect the light to the play plain noodles with great angle, later refract to target wall bottom to the light spot darkness problem that the insufficient quantity of supplementary bottom light caused, with the illumination luminance of improvement bottom, the taper structure of setting in the luminous aperture simultaneously can effectively restrain and absorb the too much uncontrollable light in the middle of, with the reduction washing wall residual light.

Further, the second reflecting surface is a convex second reflecting cambered surface, and the second reflecting cambered surface is a free-form surface and is used for gathering the reflected light rays.

The light rays are gathered towards the middle of the lens through the arc-shaped second reflecting surface, so that the irradiation height of the wall washing is improved.

Further, the free curvature radius of the second reflecting cambered surface is 40-80mm.

Further, the third reflecting surface is a third reflecting straight surface to reflect the light leaked through the sharp corner of the light emitting hole.

Further, the height range of the first reflecting surface and the third reflecting surface is 1.5-3mm.

Further, the height of the second reflecting surface is in the range of 12-15mm.

Further, the surface of the conical structure is provided with sun prints.

The middle uncontrollable light is further absorbed through the matching of the sun print and the conical structure, so that the residual light of wall washing is reduced.
