PURPOSE: An LED lighting apparatus is provided to combine a plurality of light source blocks with different illuminating angles and brightness in a housing plate by assembling the blocks, thereby enabling to accomplish design modification. CONSTITUTION: A housing plate has a polygon plate shape. Each top end part of a plurality of light source blocks(110a,110b,110c,110e-110k) is combined on each lateral side of the polygon of the housing plate in order to be able to be attached and detached. A plurality of LED modules(140) is established in order to distribute light with different illuminating angles along a predetermined illumination curve. At least some light distribution directions of a plurality of light source blocks are established in deviated directions from the central axis of housing. |
