Technical Field

[0001] The present application relates to the technical field of landscape lighting lamp stands, and in particular to an adjustable lighting lamp stand. Background Art

[0002] Landscape lighting refers to outdoor lighting projects that have both lighting functions and artistic decoration and environmental beautification functions. It usually uses a 4-5 meter lamp stand, which is suspended in the air to shape the outlines of vegetation, buildings, etc., enrich the lighting levels of the courtyard at night, and highlight the charm of the landscape. However, since the lighting stand is too high, when the lighting fixture is damaged, it is necessary to manually climb the ladder to repair it. If a single person works, there is a problem that the ladder is unstable and easy to fall. Therefore, at least one staff member is required to support the ladder on the ground for safe operation. The maintenance of this type of lamp stand is inconvenient and wastes manpower, so it needs to be improved. Utility Model Content
