As the utility model discloses further improve, snoot bottom bilateral symmetry is equipped with the guide part, guide part center processing through-hole runs through the snoot upper surface, inner chamber bottom processing spacing groove with the guide part corresponds, still process in the middle of the snoot bottom and keep away empty portion.

As the utility model discloses further improve, spacing groove bottom processing screw hole, the guide part stretches into the spacing groove is through the bolt fastening.

As a further improvement, the lower part of the guide part is chamfered.

As a further improvement, the light-reflecting cup is close to the light opening is processed into to the lateral wall lower part of light source subassembly, anti-light cup open-top forms the second light-emitting window, go into the light opening with first light-emitting window is corresponding.

As a further improvement, the light reflecting surface is processed in the light reflecting cup and is of a light condensing structure, and the concave surface of the light reflecting surface is opposite to the light source component.

The utility model has the advantages that:

this structure is through setting up the snoot that has hemisphere condensing surface between light source and anti-light cup, and the light source is at first carried out polymerization back reflection to anti-light cup in the snoot, then is reflected by anti-light cup and jets out after lens refract, effectively prevents the loss of dispersing of light source, improves the light source utilization ratio.
