Description

Technical Field

[0001] The utility model relates to the technical field of LED spotlights, in particular to an adjustable LED spotlight. Background Art

[0002] An LED spotlight is a spotlight using a light-emitting diode as a light source. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, consume a lot of electricity, cause the temperature of the irradiated environment to rise, and have a short service life. LED light sources are far superior to traditional lighting fixtures in terms of the light-emitting principle, energy conservation, and environmental protection. They are mostly used in various usage scenarios such as hotel decoration, company office, and clothing display.

[0003] Based on the above, the inventor found that when an LED spotlight is in use, due to its fixed light irradiation angle and the fact that the LED spotlight itself cannot be telescoped, its usage function is relatively single. Therefore, in view of this, the existing structure is studied and improved to provide an adjustable LED spotlight, in order to achieve a more practical value purpose. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

One side of the inner sphere is fixedly connected with a fixed rod, and the other side of the fixed rod is fixedly welded with a telescopic assembly. The inner side of the telescopic assembly includes a number of limiting grooves. A telescopic lamp post is inserted and installed inside the telescopic assembly. A rectangular groove is formed on one side surface of the telescopic lamp post, a limiting spring is installed inside the rectangular groove, and a limiting block is arranged above the limiting spring. The limiting block is engaged with the limiting groove inside the telescopic assembly.
