technical field

The utility model relates to the field of stage lamps, in particular to a stage lamp with both waterproof and heat dissipation functions.

Background technique

Waterproof stage lights require a waterproof design for the product, and because the power of the light source used in stage lights is generally relatively high, it is also necessary to design heat dissipation for the heat source. The existing heat dissipation technology is generally that the heat sink is pasted on the heat source. After adding the fan, the external cold air needs to flow in continuously to cool the heat source. However, because this kind of stage light needs to be designed as a sealed cavity to ensure the waterproof function of the stage light , so there is no outside cold air to flow into the sealed cavity. If the heat dissipation is designed according to the conventional method, the radiator needs to be made very large, the fan must be large, and the casing must be large to meet the requirements, so the product is not cost-effective at all.
