LED LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an LED lighting device which uniformly diffuses LED light in an illumination surface direction and obtains uniform light effect by a simple structure.SOLUTION: An LED lighting device includes: an LED lamp body 21 including an LED substrate on which LED elements are mounted and a lighting circuit board which drives the LED substrate to cause the LED substrate to light; a shield member 27 which covers a region of an electronic component mounted on the lighting circuit board; a light diffusion member 40 disposed at the light irradiation surface side of the shield member 27; and a translucent cover 28 disposed at the light irradiation surface side of the light diffusion member 40. A rib which closely contacts with an end edge part of the translucent cover is formed at the light diffusion member 40. The shield member 27 is translucent.
