<p>The present invention relates to the heat radiation structure of a fishing lamp with a housing forming a cavity. The LED fishing lamp of the present invention includes the housing in which multiple LEDs are installed to emit light to the outer side and which forms a cavity; multiple radiation fins protruding from the inner wall of the housing; and a blowing fan installed on the upper or lower part of the cavity and discharging air which is sent to the cavity from the outside of the cavity. The fishing lamp of the present invention has little energy consumption using the LEDs as light emitting bodies and the excellent efficiency of radiating heat as a structure in which the cavity caused by the installation of the LEDs in the front and rear sides of the fishing lamp is formed and which includes the multiple radiation fins positioned on the inner wall of the cavity and the blowing fan positioned on the upper or lower part of the fishing lamp enables outside air to pass through the radiation fins after being sent to the cavity by the blowing fan at the same time. Furthermore, when an air flow passage setting body blocking the central part of the cavity in the lower side of the blowing fan to allow a suction force caused by the blowing fan to act along the inner wall of the cavity is additionally equipped, the efficiency of making the outside air pass through the radiation fins is excellent so that the fishing lamp has more excellent efficiency of radiating heat.</p> |
