TECHNICAL FIELD

[0001] The present application relates to the technical field of stage light, in particular to a stage light with compact heat dissipation structure. BACKGROUND

[0002] The heat sink of the stage light comprises a uniform temperature plate, a plurality of heat pipes, a first heat dissipation fin group and a second heat dissipation fin group. Specifically, the bottom of the uniform temperature plate is connected with the first heat dissipation fin group through the heat pipes, and both ends of the uniform temperature plate are connected with the second heat dissipation fin group through the heat pipes. The first heat dissipation fin group and the second heat dissipation fin group are correspondingly provided with heat dissipation fans for dissipating heat of themselves. Generally, the first heat dissipation fin group and the second heat dissipation fin group are arranged at positions close to each other. Therefore, the cold air driven by the air inlet is easily mixed with the hot air of the air outlet, so that part of the cold air is exchanged with the hot air just discharged before entering the heat sink, thereby reducing the cold air exchanged with the heat dissipation fins in the heat sink, and causing the heat dissipation efficiency of the heat sink to be low, affecting the heat dissipation of the light source, and easily causing the phenomenon of the light source due to the high temperature of the light source.

[0010] Further limited to, the housing is provided with a heat dissipation hole, the heat dissipation space is communicated with the outside through the heat dissipation hole, so that the second heat dissipation fan drives the airflow to pass through the heat dissipation space from top to bottom and then is discharged outside the housing from the heat dissipation hole.

[0011] Further limited to, the partition plates located at the same side left end and the same side right end are integrally connected with a connecting plate, and the partition plates and the connecting plate form a surrounding plate for surrounding the heat radiator.

The bottom end of the second set of heat dissipation fins 24 and the bottom end of the first set of heat dissipation fins 23 are not at the same height, so that there is space at the bottom of the heat sink 2, and the partition plate 31 can well isolate the heat dissipation space 30 from other internal spaces, preventing the airflow through the heat dissipation space 30 from mixing with other internal airflows, thereby avoiding the situation of low heat dissipation efficiency.

[0023] In the embodiment, the first heat dissipation fans 4 are connected between the partition plates 31 at the same side front end and the same side rear end, and the two first heat dissipation fans 4 are respectively opposite to the front and rear ends of the first heat dissipation fin group 23.
