Kind Code:
A1
Abstract:
The present invention relates to an LED lighting device comprising: a diffusion part which is in the shape of a canister having an opened upper surface and has a through-hole provided at the center of the lower surface thereof; a substrate fixing part which fixes a substrate, having an LED mounted thereon, at the lower side of the through-hole of the diffusion part in a state in which the substrate is inserted through the through-hole; and a reflection part which has the center of a lower surface brought into contact with the central part of the substrate and provides a reflection surface having a curved surface so that the gap with the diffusion part increases toward the edge thereof. The present invention has the effect of illuminating an entire ceiling with even light distribution because of installation at the center of the ceiling, thereby being capable of preventing occurrence of glare phenomenon and enabling indirect lighting to be used as main lighting.
