PURPOSE: A power LED lamp is provided to reduce damage to crops by preventing exposure of illumination about an unnecessary part through rectangular light distribution. CONSTITUTION: A power LED lamp body(10) includes a plurality of tilted side lighting parts(11,12,13), a plurality of connecting parts(14,15), and a floor lighting part(16). The tilted side lighting parts have a tilting lighting angle. The tilted side lighting parts are symmetrically formed according to a longitudinal direction of light distribution region. Each connecting part connects the tilted side lighting parts which are vertically adjacent. The floor lighting part connects the tilted side lighting parts which are horizontally adjacent. A plurality of power LED devices(20) is arranged in the tilted side lighting parts and the floor lighting part with a fixed interval in order to light the light distribution region with a rectangular pattern. A power LED driving module(30) supplies a driving power to the power LED devices.
