PURPOSE: An LED(Light Emitting Diode) type lighting apparatus including a light path guide board is provided to collect light at a predetermined direction by forming an optical path guide plate. CONSTITUTION: A PCB(Printed Circuit Board)(100) provides power to an LED by electrically connecting to the LED. The PCB includes a heat radiation board(500). A plurality of LED(200) emits light by being installed on the PCB. A first light path guide board(300) applies light emitted from the LED to the vertical rising unit of the PCB. The first light path guide board projects the light path to the outside. A light penetration tube(400) is connected to the first light path guide board. |
