LED street lamp

Abstract

The invention discloses an LED street lamp. The LED street lamp comprises a base; a first chute is formed in the upper end of the base; a first through hole communicated with the inside and the outside is formed in the side wall of the front end of the first chute; a rotating rod is arranged in the first through hole in a penetrating manner; the end, positioned in the first chute, of the rotatingrod is connected with a gear in a sleeving manner; the end, positioned out of the first chute, of the rotating rod is connected with an annular piece in the sleeving manner; a fixed device is arrangedon the side wall of the front end of the base; the fixed device is positioned right above the rotating rod; two first sliding blocks are arranged in the first chute; the two first sliding blocks arerespectively arranged in the positions, on the left side and the right side of the rotating rod, in the rotating rod; moving plates are horizontally arranged on the opposite side walls of the two first sliding blocks; the moving plates are respectively arranged in the positions, on the upper side and the lower side of the rotating rod, of the first chute; gear racks are arranged on the opposite side walls of the two moving plates; the gear racks are engaged with the gear; a supporting post is arranged on the base. The LED street lamp is convenient to maintain and convenient to move.

Description

[0001] technical field [0002] The invention relates to the technical field of LED street lamp equipment, in particular to an LED street lamp. Background technique [0003] LED street lamps are semiconductor lighting lamps, which use light-emitting diodes as light sources. Because they are a solid-state cold light source, they have the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. The overall low light efficiency of high-pressure sodium lamps has caused a huge waste of energy. High-quality street lamps are of great significance to urban lighting and energy saving. The existing LED street lamps are fixed on the road, which is not easy to move, has low flexibility, and the height is fixed and non-adjustable, which is convenient for maintenance of LED lamps.
