AI Technical Summary
There are contradictions in existing high-power LED searchlights in terms of waterproofing and heat dissipation. High waterproofing levels will lead to degradation of heat dissipation performance. The traditional worm gear or spur rack structure leads to huge volume and complex structure, which limits the miniaturization of searchlights.
A searchlight was designed, using a light source cavity and a heat dissipation cavity to separate the light source cavity, and isolate it with a radiator in the middle, and improve the heat dissipation effect through hollow design and multiple heat dissipation holes. Combined with a high waterproof seal ring and buckle assembly, it achieves high waterproof grade and good heat dissipation. Take into account both performance.
It achieves a balance of high waterproofing grade and good heat dissipation performance, ensuring reliable long-distance lighting and target search capabilities for high-power LED searchlights in marine applications, while reducing equipment volume and structural complexity.

[0007] Furthermore, the pressure ring component seals the sealing strip and the lamp tube via a buckle assembly, and the radiator is seal-connected to a radiator mounting plate in the lamp tube via a waterproof sealing ring.
[0008] Furthermore, a plurality of heat dissipation holes which are staggered are formed on the rear cylinder of the lamp tube component.

[0010] Furthermore, the high-power light-emitting lamp is a 100W-200W LED lamp bead.

[0025] The searchlight of the utility model adopts an independent waterproof design for the light source cavity and the heat dissipation cavity. The light source cavity needs to be highly waterproof, and the heat dissipation cavity needs to be low waterproof because it needs to dissipate heat. A heat dissipation module is used in the middle as a waterproof isolation, and the heat generated by the high-power LED in the light source cavity is conducted to the heat dissipation cavity through the heat dissipation module, and then the heat is taken away by convection between the heat dissipation cavity and the outside atmosphere. In this way, a high waterproof level is basically achieved without affecting the heat dissipation performance.

The waterproof sealing ring 7 is two O-rings, and the cable lock is used to lock and seal the lamp at the wire crossing, so that the light source cavity forms a closed environment. It has good waterproof and dustproof performance and can reach IP66 level.
[0027] The utility model provides a searchlight, wherein the high-power light emitting lamp is a 100W-200W LED lamp bead, and the diameter of the radiator is 240mm, which increases the heat dissipation effect. At the same time, the rear part of the lamp tube is hollowed out to effectively take away the heat of the radiator through natural wind.
[0028] The searchlight provided by the utility model, the control box mechanism in the pan / tilt component 3 uses a motor reducer integrated power source, and a gear direct drive method to realize the transmission structure of horizontal and vertical rotation of the lamp, which has the characteristics of compact structure, stability and high efficiency; and the control box has a high protection level, which greatly increases the service life of internal components.
