Detailed Description

As shown in fig. 1 to 4, the pannier according to the present embodiment includes a front cover 40, a rear cover 10, and a heat sink 30 disposed between the front cover 40 and the rear cover 10; the radiator 30 is of a hollow structure, a control circuit element 32 is arranged in a cavity of which the middle part is surrounded by a partition plate 36, a sealing cover plate 20 is arranged at the tail end of the cavity, and radiating fins 35 are arranged at the periphery of the partition plate 36; a fan 21 is installed on the outer side of the sealing cover plate 20, and a vent hole 11 is formed in a position, corresponding to the fan 21, of the tail cover 10 for conveying air to the fan 21; the rear ends of the heat dissipation fins 35 form a nesting part 34 which is sleeved with the inner wall of the tail cover 10, and the front ends of the heat dissipation fins 35 are exposed (exposed between the front cover and the tail cover after assembly) to dissipate heat. In operation, a plurality of channels are formed between the inner wall of the tail cover 10 and the nesting parts 34 of the heat dissipation fins, and the air flow sucked by the fan 21 from the vent hole is guided to enter the tail cover, and the heat is dissipated outwards from the front ends of the heat dissipation fins 35 after passing through the channels.

Further, on the lamp housing of the pani, a convex cover 13 is provided at a position of the tail cover 10 corresponding to the fan 21, and a plurality of ventilation holes 11 are provided on the convex cover for guiding external air into the rear cover (when the fan works). A slot 12 is also provided in the tail cap 10 below the nose cap 13 for mounting a control panel 22. In the lamp of the pani lamp, as shown in fig. 4, a limit step 31 is formed between the nesting part 34 at the rear end of the heat dissipation fin and the fin 35 at the front end, so that the tail cover 10 is positioned at the step when being sleeved with the nesting part 34; the heat dissipation fins 35 are radially distributed on the periphery of the partition plate 36. The butt joint of the cavity tail end of the radiator 30 and the sealing cover plate 20 is provided with a sealing rubber ring 23, the sealing cover plate 20 is also provided with a wire hole and a hole site for installing the control panel 22, and the wire hole and the control panel are exposed through the slot 12 on the tail cover, so that the lamp is convenient to operate.

The front cover 40 is provided with a mounting plate 41 of a light emitting member 43, and a sealing rubber ring 42 is provided between the front cover 40 and the radiator 30.
