PURPOSE: A diffusion type LED lighting device is provided to save energy by preventing a shadow region due to a light angle property emitted in an LED lamp. CONSTITUTION: A diffusion type LED lighting device includes a printed circuit board(100) of flexible material, a heat sinking part(200), a housing(300), and a light angle control part(400). A plurality of LED lamps(110) are faced on the printed circuit board. The heat sinking part is positioned in one side of the printed circuit board. The heat sinking part emits a heat generated in the LED lamp and the printed circuit board. The printed circuit board and the heat sinking part are received in the housing. The light angle control part controls a light distribution curve and a light angle emitted in the LED lamp. |
