PURPOSE: A searchlight of a ship which significantly improves heat dissipation efficiency is provided to improve heat dissipation efficiency of a heat dissipation unit, to reduce an unnecessary waste of energy, to reduce production costs, and to improve productivity by forming the heat dissipation unit through extrusion-molding an aluminum material which has an excellent heat exchange efficiency, thereby significantly improving heat dissipation efficiency. CONSTITUTION: A searchlight of a ship includes a light emitting unit(10), a heat dissipation unit(20), and an inflow unit. The light emitting unit is composed of LEDs(120) which are provided with a fixed space between each other on a substrate and on the front side of the substrate. The heat dissipation unit(20) is composed of an outside pipe which is provided on the light emitting unit and an inside pipe which is provided inside the outside pipe. The outside pipe is flowed inside with high temperature heat which is generated from the heat dissipation unit, and discharges the high temperature heat, which is flowed inside, to the outside after the high temperature heat is exchanged with the external air; and made by protrusion-molding. The inflow unit makes the external air inside through convection current according to a temperature distance between the high temperature heat which is flowed inside the heat dissipation unit and the external air on the periphery of the heat dissipation unit. |
