Description

Technical Field

[0001] This utility model belongs to the field of light source equipment technology, specifically, it relates to a novel waterproof and heat dissipation structure for light sources. Background Technology

[0002] For outdoor lighting equipment, such as LED streetlights, landscape lights, and stage lights, the heat dissipation performance directly affects the luminous efficiency and lifespan of the light source.

[0003] Utility model CN219588893U discloses a light source heat sink, comprising: a thermally conductive substrate; and a thermally conductive assembly connected to the thermally conductive substrate. The thermally conductive assembly includes multiple heat pipes, each comprising a central portion and a radiating portion. Each central portion is located at the center of the thermally conductive substrate and clustered together. The multiple radiating portions extend away from the central portions, and the spacing between adjacent radiating portions gradually increases. This application, by arranging the heat pipes of the thermally conductive assembly in a centrally clustered and externally radiating pattern, can transfer the central heat of a light source module with a relatively small heat source area to the periphery of the heat sink, effectively reducing the temperature difference between the center and the outer side of the light source or heat sink, resulting in more uniform heat distribution and improved heat sink performance.

[0004] However, the aforementioned patents still have the following problems: Some lighting fixtures use fans to dissipate heat, and to improve heat dissipation efficiency, high-speed fans are usually equipped to accelerate airflow and achieve rapid heat dissipation. When used outdoors or in humid environments, existing heat dissipation structures have obvious defects. When encountering rain or humid weather, water can easily enter the air inlet and outlet, and the airflow generated by the high-speed rotation of the fan may bring water droplets into the light source, causing serious problems such as short circuits and component damage, affecting the normal operation and safety of the light source equipment.

[0005] In view of this, this utility model is proposed. Utility Model Content
