Energy-saving street lamp easy to wash

Abstract

The invention relates to the field of public facilities, in particular to a street lamp. The energy-saving street lamp easy to wash comprises a base, a lamp pole and a lamp cap assembly, and the lamp pole is fixedly installed on the base. The street lamp is characterized in that a screw is vertically arranged in the lamp pole through a pair of bearings, the screw is provided with a screw nut, the screw nut is fixedly provided with a supporting beam, the lamp cap assembly is fixedly installed on the supporting beam, the bottom of the lamp pole is provided with a hand wheel, and the hand wheel drives the screw to rotate through a gear set. The lamp cap assembly can move up and down along with the lamp pole, the lamp pole is installed on the screw nut and cannot slide down usually due to the self-locking function of a screw pair, when the street lamp needs to be cleaned and maintained, the lamp cap assembly can be lowered through the hand wheel, a cleaning worker can maintain the street lamp conveniently, and accordingly the light transmittance of the lamp cap assembly can keep in an original state for a long time, light transmittance loss caused by dust is reduced and consumption of electricity is reduced.

Description

technical field [0001] The invention relates to the field of public facilities, in particular to a street lamp. Background technique [0002] In a modern city, in order to ensure the lighting of the city, a row of street lights will be installed on both sides of each road as lighting equipment; the existing street lights usually use a light pole fixed vertically on the ground and fixed on the top of the light pole Consisting of a lamp head; the welding method of the lamp pole is automatic submerged arc welding, the welding is reliable, the surface is smooth, there are no obvious welding defects such as pores, welding tumors, undercuts, etc., ultrasonic flaw detection inspection, steel pole anti-corrosion treatment adopts internal and external hot-dip galvanizing, galvanized The process has gone through pickling, hot-dip galvanizing, water washing, phosphating, passivation and other processes. The surface of the galvanized layer is smooth and beautiful, with consistent luster...

AI Technical Summary

Problems solved by technology

[0003] Existing street lamps of this type are basically unable to be cleaned and maintained because of their high height. The initial light transmittance of curved high-strength tempered glass is about 85%. After a period of use, it may drop to 65%, so that a large part of the light energy ratio will be wasted, which will affect the lighting effect of the city. In order to ensure the lighting of the city, it is necessary to use a higher power light source, which will waste electric energy
