The invention discloses a high-pole lamp which comprises a mounting pole, a plurality of lamp cap brackets and lamp caps, wherein the mounting pole is vertically arranged; the lamp cap brackets are arranged at the upper end part of the mounting pole and are horizontally arranged; the lamp caps are arranged on the corresponding lamp cap brackets; a plurality of light emitting devices are arranged on the lamp caps and are arranged in an array manner; each light emitting device comprises a lens and an LED light-emitting part coupled with the lens; each lens is an axisymmetric entity made of transparent material and comprises a substrate surface, an inner surface, an outer surface and an output end which comprises a plurality of repeating units and is of a saw tooth shape; each substrate surface is adjacent to each LED light-emitting part; each inner surface extends from each substrate surface and is provided with a circled inner lateral surface formed around a center line of each lens and an upward-protruded arc-shaped inner end surface; each inner surface is a light incident surface; each outer surface is a light reflecting surface; each repeating unit comprises an arc-shaped outer end surface positioned on one side of the repeating unit, an outer end surface positioned at the other side of the repeating unit, a tip arc-shaped surface connected to the tip of the adjacent arc-shaped outer end surface and the tip of the outer end surface as well as a root arc-shaped surface connected to the root of the adjacent arc-shaped outer end surface and the root of the outer end surface.
Description
technical field [0001] The invention relates to an LED high pole lamp. Background technique [0002] At present, the light output device on the lamp head of the high pole lamp or the square lamp is only an LED light emitting part, and its light distribution is characterized by a large direction angle, and then the light distribution reduces the illumination of the irradiated area, and the range of the irradiated area is small , It cannot meet the characteristics of high pole lights or square lights with small direction angle and high illumination requirements. Contents of the invention [0003] In order to overcome the above disadvantages, the purpose of the present invention is to provide an LED lens light-emitting device, by installing a lens in front of the LED light-emitting component, the direction angle is small and the illuminance is significantly improved. [0004] In order to achieve the above purpose, the present invention provides a high-mast lamp, which includ...
