The fixing bracket 122 is correspondingly provided with a light exiting hole 1227 for the light emitted from the light source to exit. A bottom of the upper shell 11 is provided with an abutment surface 112 to be cooperated with the fixing bracket 122, and the abutment surface 112 is provided with an installation hole, and the installation hole can be a screw hole or a wire hole through which the power line 123 passes.

As shown in FIG. 8, FIG. 11, and FIG. 12, in the above mentioned embodiment, the base substrate 121 and the fixing bracket 122 are fixedly connected with each other by a fastener (not labeled), which can be a bolt or other structures. One end of the power line 123 is welded and fixed below the base substrate, and extends out of the base substrate 121. The fixing bracket 122 is configured to install the base substrate 121, and to clamp and arrange the power line 123 between the base substrate 121 and the fixing bracket 122 to achieve a wire fixation of the power line 123.
In a preferred embodiment of the present application, the fixing bracket 122 is arranged below the base substrate 121, and one side of the fixing bracket 122 is provided with a wire fixing member 1221 formed by extending downwardly for fixing the power line 123. Further, the wire fixing member 1221 is partially cut away to expose a welding window of the base substrate 121, through which the power line 123 can be welded onto the base substrate 121 or a welding joint can be repaired. The wire fixing member 1221 is recessed downwardly from a plane where the fixing bracket 122 is located, to form a concave part 1222 for accommodating the power line 123. Two sides of the concave part 1222 are provided with a locking part 1226 respectively, and the concave part 1222 is connected to the abutment surface 112 through the locking part 1226 to clamp and arrange the power line 123 between the abutment surface 112 and the concave part 1222. The locking parts 1226 are arranged on two sides of the concave part, and locking holes are formed in the locking parts 1226, so that the concave part 1222 and the abutment surface 112 can be locked and fixed with each other by using locking members to pass through the locking holes. Further, the fins are perpendicular to the abutment surface 112 and are arranged above the abutment surface 112. When the fixing bracket 122 is connected to the abutment surface 112, the abutment surface 112 is abutted against the base substrate 121, that is, the heat generated by the base substrate 121 is transferred to the abutment surface 112 and the fins in sequence to complete the heat dissipation.

Preferably, the fixing bracket 122 is also provided with reinforcing ribs (not labeled) to further enhance the structural strength.
Further, the concave part 1222 is provided with a sawtooth structure 1225 abutted against the power line 123.
