Abstract
An LED lighting apparatus includes a support unit including a support surface facing an illumination side, a plurality of LED chips supported on the support surface, and a cover that covers the support surface and transmits light from the LED chips. The cover includes a periphery which, as viewed in plan, includes four first sides that are spaced apart from each other and four second sides each connecting ends of adjacent ones of the first sides. The first sides consisting of two pairs of parallel sides, and each of the first sides constituting one of the two pairs and each of the first sides constituting the other one of the two pairs form a right angle. Each of the first sides and each of the adjacent second sides form an obtuse angle.
