This new utility invention discloses a waterproof LED lamp comprising a power supply box and an LED lighting module block detachably connected to the power supply box. A power driving board and an LED controller are disposed in the power supply box. The LED lighting module block includes at least one LED module, which includes a module heat dissipater. The power supply box and the LED module are arrayed side-by-side in a parallel manner, and a lateral surface of the power supply box matches a lateral surface of the LED module in size and shape so that the power supply box and the LED module may be in close contact. The power supply box and the LED lighting module block are electrically connected with a conducting wire, which is arranged to go through the wiring hole and the slot. The power driving board provides power to the LED controller and the light board, and the LED controller drives the LED lighting beads on the light board to illuminate. The present invention disposes the power supply and power driver inside a power supply box to separate the power supply from the LED light source. For product maintenance, the power supply or LED light source may be replaced individually.
