A LED module and a manufacturing method thereof are provided to enhance waterproof performance by arranging a lens member on a PCB substrate and forming an external coating part on the lens member. A plurality of LEDs(21) are mounted on a PCB substrate(20). A base includes a reception part(11) on which the PCB substrate is arranged, a waterproof filler injection hole(111) formed in the reception hole, a fixing guide(112) for PCB substrate, and heat-radiating holes(113) for LEDs. A power supply line(30) is extended between the base and the PCB substrate to supply power to the LEDs. A lens member(40) includes a light-transmitting coating part(41) for covering each of the LEDs on the PCB substrate, and a flat part for covering the PCB substrate. An external coating part is formed to cover the flat part of the lens member and to expose the coating part to the outside.
