PURPOSE: A PCB(Printed Circuit Board) having a via hole, and an LED(Light Emitting Diode) module and an LED lighting device having the same are provided to quickly radiate heat to a heat radiating plate with a through-hole between the LED chips. CONSTITUTION: An LED(Light Emitting Diode) lighting device having an LED module includes an LED chip, a PCB(Printed Circuit Board), an elastic heat radiating sheet(300), and a heat radiating plate(400). The elastic heat radiating sheet receives heat from the LED chip. The heat radiating plate radiates the heat outside. A through-hole is formed between the LED chips. A communicating hole(410) is formed on a portion corresponding to the through-hole. The elastic heat radiating sheet has a first, a second, and a third protrusion. |
