Novel reflector of tennis court anti-glare lamp

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

technical field [0001] The invention belongs to the technical field of anti-glare lamps for sports venues or venues, in particular to a new type of reflector for anti-glare lamps for tennis courts. Background technique [0002] At night or when the environment is dark, sports venues or venues need to turn on lighting fixtures. These lighting requirements are very high, mainly focusing on the three aspects of range, ground light intensity and anti-glare. This is because the lighting fixtures are generally installed higher. The area that needs to be covered and irradiated is relatively large, and it cannot interfere with the normal progress of the competition or practice. Among the existing lamps, high-pressure sodium lamps with reflectors are more commonly used. The high-power and high-luminous flux characteristics of high-pressure sodium lamps are used to meet the requirements of illuminance per unit area. , It is necessary to install ancillary equipment on the lamp, result...

Problems solved by technology

[0003] In order to solve this problem, people have developed high-brightness LED lamps. These LED lamps are installed in a convex lens, and the convex lens is used to converge and enhance the light and then project it out. The overall power is small and the power is saved. The efficiency is low, the ground will produce light spots, and the glare index is high, which cannot meet the needs of anti-glare
