LED lighting apparatus having an adjustable light distribution

摘要

An LED lighting apparatus having adjustable light distribution comprises: 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.

1. An LED lighting apparatus capable of adjusting light distribution, the apparatus comprising:
a support panel that has a plurality of heat dissipation fins on a rear surface thereof and provides a support surface; a substrate coupled to the support surface of the support panel, a plurality of LEDs being mounted to the substrate; and a reflection surface located on a front surface of the substrate, that forms a light distribution pattern on the ground by reflecting light emitted from the plurality of LEDs, wherein the heat dissipation fins and the support panel that provides the support surface are integrally provided, and the reflection surface is provided at an inner surface of a light distribution pattern portion provided to be separable from the support surface, and wherein the light distribution pattern portion comprises a division portion that divides the LEDs of the substrate into a left side and a right side with respect to a center of the reflection surface and extends toward a lower side.
