Height-adjustable LED illuminating street lamp

Abstract

The invention discloses a height-adjustable LED illuminating street lamp which comprises an installation base and a hollow cylindrical street lamp post. The street lamp post is sleeved with an installation sleeve, two installation grooves are symmetrically formed in the outer side wall of the installation sleeve, LED street lamp panels are arranged in the installation grooves, tempered glass plates of the LED street lamp panels are arc plates, the bending radian of the arc plates is matched with the outer side wall of the installation sleeve, a motor is arranged in the installation base, the output end of the motor is arranged to an adjusting screw rod, one axial end of the adjusting screw rod is connected with the motor, the other axial end of the adjusting screw rod stretches into the street lamp post and is fixed to a limiting plate through a bearing, the adjusting screw rod is sleeved with an adjusting ring, the inner wall of the adjusting ring is in threaded connection with the adjusting screw rod, the outer wall of the adjusting ring is symmetrically and convexly provided with limiting rods, the side wall of the street lamp post is provided with two limiting grooves matched with the limiting rods, and the axial ends of the limiting rods penetrate through the corresponding limiting grooves and then are connected with the inner wall of the installation sleeve. By the adoption of a lifting structure, a worker can carry out overhaul conveniently, and operation is convenient.

Description

technical field [0001] The invention relates to a lighting device, in particular to a height-adjustable LED lighting street lamp. Background technique [0002] Road lighting is an important part of urban lighting. Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. Street lamps are widely used in various places where lighting is required. Traditional street lamps often use high-pressure sodium lamps to emit light at 360 degrees. The disadvantage of large light loss has caused a huge waste of energy, and the energy consumption is high and the practicability is poor. In addition, in the case of spacious roads or suburban areas with relatively spacious roads, when two LED light panels are installed on the same street light pole to illuminate the roads on both sides at the same time, the height of the street light pole is set higher to expand the lighting range. When installi...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the height of the street light pole is high, and the lighting range is expanded. When maintaining the LED light board, it is necessary for the staff to climb the road light pole for maintenance, which is inconvenient to operate and has potential safety hazards. The purpose is to provide height-adjustable LED lights. The lighting street lamp adopts the lifting structure, which is convenient for the staff to overhaul and easy to operate.
