Abstract
The utility model discloses a light-emitting diode (LED) fish lamp with an improved heat dissipation function, which comprises a shell, a flexible printed circuit board (PCB), a lithium magnesium alloy radiating fin and an aluminum radiator. A plurality of LED lamps are disposed on the front side of the flexible PCB which is arranged in an inner cavity provided with the shell, and the back side of the flexible PCB is fixed on the lithium magnesium alloy radiating fin which is fixed on the aluminum radiator. By adding the lithium magnesium alloy radiating fin with high coefficient of heat conductivity, the LED fish lamp has high speed of heat conductivity and quickly conducts heat generated when the flexible PCB works to the aluminum radiator. The heat accumulated on the flexible PCB is very little so that the fact that the PCB has low temperature is ensured. The LED fish lamp is simple in structure, low in cost, high in heat dissipation speed and good in heat dissipation effect, improves luminous efficiency of the LED lamp of the flexible PCB, and prolongs service life of the LED fish lamp of the flexible PCB.
