PURPOSE: An LED(Light Emitting Diode) lamp module having a first and a second latching protrusion is provided to mount intact the module on the lamp mounting hole of an existing lamp mounting substrate, thereby increasing the power efficiency. CONSTITUTION: An LED(Light Emitting Diode) lamp module having a first and a second latching protrusion includes a printed circuit board(110), a holder, a first latching protrusion, and a second latching protrusion. An LED element is mounted on the center of one surface of the printed circuit board. Multiple connection electrodes are placed at the edge of the one surface. The holder has multiple protrusive hooks. The first latching protrusion for mounting the holder on a lamp mounting substrate is formed on the outer surface of the hook. The second latching protrusion for coupling the printed circuit board to the holder is formed on the inner surface of the hook. |
