This invention discloses a multifunctional fish-attracting lamp, which includes a bracket and a power supply box. The fish-attracting lamp also includes: a
heat sink fixed to the end of the bracket, with a rear shell fixed to the front end of the
heat sink; a cooling fan fixed in the center of the rear shell; a temperature controller fixed in one side of the
heat sink fins; and a fan intelligent
monitoring system embedded in one side of the rear shell. Several cooling fins are stacked from the outside to the inside at the rear end of the heat sink, and are evenly distributed circumferentially at the rear end of the heat sink. The gap between two adjacent cooling fins forms a through groove that is connected longitudinally and laterally. When the fan intelligent
monitoring system detects abnormal operation of the cooling fan, it can automatically
cut off the power supply to the lamp. When the temperature controller detects that the temperature of the heat sink exceeds 80°C, it can automatically
cut off the power supply to the lamp. The through groove not only allows the air blown by the cooling fan to diffuse to various positions behind the heat sink, but also effectively guides water and air entering the lamp.
