Abstract (en)
The present invention relates to an LED lighting apparatus which has uniform illumination and increases heat-dissipation effects to improve stability. The LED lighting apparatus includes: a panel having a plate shape, wherein the panel has a first plane and a second plane disposed on the side opposite to that of the first plane; a light-emitting part disposed on the first plane of the panel and including a plurality of LED devices, wherein the light-emitting part has a light-emitting surface parallel to the first plane and inclined at a first angle such that the light-emitting surface forms an acute angle with the ground; and a reflective plate extending from the panel. The reflective plate includes a first portion extending at an incline so as to form a second angle with the ground that is smaller than the first angle, a second portion extending from the panel at an incline in a direction away from the ground, and a third portion connecting the first portion to the second portion.
