Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to a heat dissipation device for a waterproof stage light and a stage light itself. Background Technology

[0002] Stage lighting fixtures, especially high-brightness, high-power stage lights, generate a significant amount of heat during operation. If this heat cannot be dissipated in time, the internal temperature of the fixture will rise, affecting its performance and lifespan. Waterproof stage lights are typically used outdoors or in humid environments, requiring excellent waterproof performance. Traditional heat dissipation methods, such as introducing external cool air through vents in the casing, while effective, severely compromise the fixture's waterproof capabilities.

[0003] Most waterproof stage lighting fixtures currently require a completely sealed and waterproof interior. They primarily rely on internal circulation within the fixture, heat conduction between the inside and outside of the fixture, or the use of coolant within the cooling pipes for heat exchange. While this sealed cooling method meets the lighting fixture's operational heat dissipation needs, water vapor vaporized by high temperatures inside the fixture, or oil vapor generated from the vaporization of lubricating oil in the stepper motor and sliding parts, circulates within the fixture with the cooling airflow. After the fixture stops working when the power is off, this vapor is absorbed onto the surfaces of various components within the fixture as it cools down. Especially when absorbed onto the bulb or optical glass components, it forms a hazy halo, affecting the light output. In the most severe cases, when absorbed onto the bulb's luminous sphere, it can affect the bulb's illumination or cause uneven heating, leading to cracking and damage to the bulb sphere.

[0004] Chinese patent CN209744337U discloses an outdoor stage moving head light internal circulating heat dissipation system that uses a circulating fan to form a circulating air path in a sealed cavity to carry high-temperature heat to low-temperature areas in order to achieve temperature balance and heat dissipation. However, it does not solve the problem of water vapor and oil vapor remaining in the lamp body. Summary of the Invention

[0005] To address the problems in related technologies, this utility model proposes a heat dissipation device and a stage lamp for waterproof stage lights. A U-shaped condenser tube is designed on the heat dissipation component at the tail of the lamp, and a filter device is installed at the air outlet. When the stage lamp dissipates heat, water vapor and oil vapor are introduced into the U-shaped condenser tube, and the condensate and oil stains are retained in the condenser tube through the filter device, thereby reducing water vapor or oil vapor in the lamp housing.

[0006] This utility model is implemented as follows:

[0016] Preferably, the middle part of the second fin group is recessed inward to form a second recess, and the U-shaped condenser tube is inserted into the second recess.

[0017] Specifically, the U-shaped condenser tube is located close to the second fin group, i.e. the heat sink, which can improve the heat dissipation effect and ensure that water vapor and oil vapor are guided and retained in the condenser tube.

[0018] Preferably, the filtration device includes oil filter cotton, which is placed over the air outlet. A hollow fixing plate is also provided at the air outlet to fix and cover the oil filter cotton over the air outlet. The hollow part of the fixing plate corresponds to the position of the air outlet.

The lamp tail heat dissipation component is located at the rear end of the lamp housing, with the heat sink placed outside the lamp housing. A U-shaped condenser tube is designed to wrap around the outside of the heat sink. An air inlet and outlet are provided near the light source heat dissipation component, and a filter device is also provided at the air outlet. The dissipated heat is introduced into the U-shaped condenser tube, and water vapor and oil vapor are also guided into the U-shaped condenser tube. The heat is cooled by the U-shaped condenser tube, and then the condensate or oil stains are retained in the condenser tube by the filter device. This effectively reduces the amount of water vapor or oil vapor in the internal circulation air path remaining inside the lamp housing during the heat dissipation process of the lamp body. This avoids the formation of a hazy halo on the surface of various components inside the lamp body after cooling, which would affect the light output effect. It also prevents the bulb sphere from cracking and being damaged due to uneven heating when it is adsorbed on the surface of the light-emitting sphere. At the same time, the oil stains and condensate mist can be quickly and centrally cleaned by staying in the U-shaped condenser tube. Attached Figure Description
