Abstract

The invention relates to a novel reflector of a tennis court anti-glare lamp. The reflector is in a rectangular pyramid frustum shape. A lower opening is in a rectangle shape; inner walls of two long sides of the rectangle are symmetrical surfaces equal in curvature; inner walls of two short sides of the rectangle are symmetrical surfaces equal in curvature. The inner wall surfaces of the reflector from an upper opening to the lower opening are provided with three circular ribs which are spaced. The section of the each rib is triangular, and the bottom of each rib is parallel to the plane of the lower opening. The reflector is in the rectangular pyramid frustum shape which is best for light condensing and strengthening; during actual use, power of LEDs is low, but the range, ground light uniformity and ground light intensity are all satisfactory, and meanwhile glaring index is low; the novel reflector is especially suitable for tennis training grounds or playing fields and has no effect on normal activities of athletes.

Description

The reflector of a kind of Novel net court anti-glare light tool

Technical field
