<p>An LED module is provided to protect a PCB(Printed Circuit Board) by filling epoxy resin or silicon in a body. A PCB is arranged inside a body of an LED module. An input part(100), an overvoltage blocking part(200), a rectifying part(300), a smoothing part(400), a current control part(500), and a plurality of LED lamps(600) are arranged on the PCB. The input part supplies a commercial AC power to the overvoltage blocking part. The overvoltage blocking part blocks an AC power source more than a fixed level. The rectifying part converts an AC current into a DC current. The smoothing part removes ripple or noise from the DC current. The current control part controls a frequency and a pulse width. A plurality of LED lamps is selectively turned on. At least one or more bolts are coupled in the PCB in order to supply a power to the PCB.</p> |
