Description

Air-flow type air-cooled lamp group

The invention relates to an air-flow type air-cooled lamp set, especially an air-cooled lamp set installed on a fishing boat for night fishing and capable of effective heat dissipation.

When fishermen go fishing at night, they will set a light source to illuminate the sea according to the phototaxis of the fish at night, and the brighter the place usually attracts more fish, so a large number of light sources are needed.

Conventional lamp units installed on fishing boats often generate a lot of heat due to the light source. Although they are equipped with heat dissipation devices, the lamp units have a short lifespan due to the inability to effectively dissipate heat. They often need to be replaced. For fishermen, it’s a big problem to constantly replace the light sets. In addition, most of the current heat sinks use general fan-blade fans, and general fan-blade fans are prone to reversal or over-rotation due to strong sea wind pressure and damage. It is also very inconvenient for fishermen.

In order to reduce the weight of conventional light sets installed on fishing boats, they are mostly made of aluminum alloy and use anodizing or spraying protective layer to achieve the effect of corrosion resistance. In the end, they are damaged when the screws are locked into the screw holes. The protective layer makes the lamp set easy to be corroded by sea water and water containing salt, causing potential corrosion between screws and screw holes to damage the air tightness of the lamp, causing leakage and moisture absorption to accelerate and reduce the service life of the lamp. In addition, for the strength of the installation of lamps, the mounting base is mostly made of stainless steel, but it is damaged when the stainless steel mounting base is locked or frictionally collided with the aluminum lamp holder, and then it is corroded by sea water and water containing salt. Accelerate the corrosion of the lamp holder and reduce the service life of the lamp holder.

Based on the above-mentioned deficiency, the present invention provides an air-cooled air-cooled lamp set that can be used for night fishing and can effectively dissipate heat.

Preferably, the upper cover has a filter plate, the filter plate is transparent or has a filter coating, so that the light source can gather the fish to approach the fishing boat.

Further, the heat dissipation unit further includes an airflow enhancement device disposed on a side of the fanless fan away from the heat dissipation fin, and the airflow output of the airflow enhancement device and the airflow output of the fanless fan face the same direction.

Further, the air flow enhancing device is connected to one of the gas input devices to serve as a gas input source.
