The present invention relates to an LED floodlight for ensuring improved illumination by facilitating the diffusion of individual light emitted from each light emitting diode arranged on the bottom of a substrate and minimizing the life-shortening of the light emitting diode due to heat through rapid dissipation of heat generated in the process of light emission. The present invention comprises a main body which has a storage space part whose lower part is opened inside; a light emitting part which is arranged inside the storage space part formed on the main body and lights up by receiving a current supplied from a power supply device; and a flood lens which closes the lower part of the storage space part storing the light emitting unit to be sealed by a flood structure. The light emitting part includes a circuit board which has a plurality of contact terminals on the bottom, wherein the contact terminal receives a current from the power supply device; and the light emitting diode which forms a contact point with the contact terminal formed on the circuit board. A reflective orientation piece having conical reflective orientation ports whose diameter is gradually greater from the upper part to the bottom part is arranged at the bottom of the circuit board composing the light emitting part. Each of the light emitting diodes formed on the bottom of the circuit board is individually stored in the reflective orientation port formed on the reflective orientation piece so the light emitted to the side part of the light emitting diode is reflected from the inner wall of the inclined reflective orientation port and is oriented toward the lower side. |
