    摘要： Disclosed and described herein is a sharp cutoff LED lighting luminaire and methods of use thereof. Further disclosed is a modification thereof which allows baseballs or detritus trapped by the luminaire to fall to the ground. In the state of the art often designers will use the same type of LED lighting fixtures at the top of the pole as for low-mounted uplighting; specifically, taking an additional fixture similarly configured, inverting the orientation (i.e., so to project upward instead of downward), and mounting it relatively low on the pole. The envisioned sharp cutoff LED lighting fixture is better suited for low-mounted uplighting insomuch that it reduces back light, haze, internal glow, and perceived glare as compared to current LED lighting fixtures typically used for the same purpose.
