The present invention relates to an LED lighting apparatus having an adjustable light distribution, comprising: a support panel on which a plurality of heat dissipation fins are disposed on a back surface thereof, the support panel providing a parallel front part which is not parallel to the ground; a board on which a plurality of LEDs are mounted, and being coupled to said front part of the support panel; and a reflection part fixed to the support panel so as to be disposed on the front surface of said substrate, and reflecting light emitted from said plurality of LEDs to provide a curved reflection surface which forms light distribution patterns on the ground. The light emission surface of the LED is not disposed parallel to the ground. The light emitted from the LED is distributed through the reflection part having a curved surface reflecting the light emitted from the LED toward the ground. Various distribution patterns may be formed according to the shape of said curved surface of the reflection part, the LED arrangement, the angle between the light emission surface of the LED and the ground, or whether or not a plane reflection part re-reflecting the light reflected by the curved surface of the reflection part exists. Thus, the LED lighting apparatus may be applied to various lighting fields using the same structure. |
