Abstract

The invention relates to an LED street lamp metal connecting device, in which wire is put into a metal hose, thereby protecting the wire from exposing to the sun and rain, prolonging the service life, making the aging of the metal hose difficult, and well solving the seal problem of the LED street lamp. One end of the metal hose is provided with a screw joint which makes the disassembly convenient during maintenance.

Description

technical field [0001] The invention relates to a metal hose connection device for an LED street lamp, which relates to a metal pipe threaded through a back cover, in particular to a metal pipe connection device applied to an LED street lamp. Background technique [0002] As the government responds to the expansion of domestic demand, the construction of municipal roads is also increasing. Compared with other street lights, LED street lights have unique advantages. The advantages of cold light source, fast response speed, high luminous efficiency and long life are unmatched by other street lights. , and the sealing problem of LED street lamp wires is also very important, which directly affects the life of LED street lamps. Contents of the invention [0003] The purpose of this invention is to solve the problem of unsealed connection of the wires of the traditional LED street lamps, so as to invent a metal hose that passes through the thread of the back cover of the lamp ho...
