LED lamp long in service life

Abstract

The invention discloses an LED lamp long in service life. The LED lamp comprises a shell and a ceiling, wherein the shell is fixed at the top of a base; the ceiling is arranged above the shell; a cavity is formed inside the shell; a first transverse cavity and a second transverse cavity are arranged inside the shell at the top of the cavity; a sliding chute is arranged at the top wall inside the first transverse cavity; a taking groove is formed in the outer wall of the shell on the right side of the cavity; a through groove and a clamp groove are formed between the taking groove and the cavity; a rotating hinge pin is arranged inside the cavity in an up and down extension manner; the top of the rotating hinge pin extends to penetrate through the inner wall of the shell to enter the first transverse cavity; a first toothed wheel is fixedly arranged at the tail end of the rotating hinge pin inside the first transverse cavity; a coiling disc is fixedly arranged on the rotating hinge pin inside the cavity; a power supply wire is coiled inside the coiling disc; a sliding block is arranged inside the sliding chute; the bottom of the sliding block enters the first transverse cavity; and a first electromotor is arranged on the bottom end surface of the sliding block. The LED lamp is simple in structure, convenient to operate and high in security, and the power supply wire can be withdrawn automatically.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED lamp with long service life for building construction. Background technique [0002] In the actual construction of the construction site, due to the tight schedule or construction needs, construction needs to be carried out at night, so the lighting on the construction site has become an indispensable tool in the construction process. However, due to the long power supply connection required in the construction lighting process , making it extremely difficult to take in and out the wires, increasing the workload and reducing work efficiency. At the same time, when not in use, the power supply wires are exposed to the outside world for a long time and are vulnerable to various accidental damages, such as people trampled on, hard objects scratches, etc., resulting in power supply failures.

[0002] In the actual construction of the construction site, due to the tight schedule or construction needs, construction needs to be carried out at night, so the lighting on the construction site has become an indispensable tool in the construction process. However, due to the long power supply connection required in the construction lighting process , making it extremely difficult to take in and out the wires, increasing the workload and reducing work efficiency. At the same time, when not in use, the power supply wires are exposed to the outside world for a long time and are vulnerable to various accidental damages, such as people trampled on, hard objects scratches, etc., resulting in power supply failures. The insulation skin on the outside of the line is damaged, and it is easy to induce electric shock accidents if it is not found in time. In addition, the existing LED lights for construction work through connection with the mains, resulting in waste of power resources. There are major drawbacks and need to be improved.
