AI Technical Summary

Technical Problem

When the lighting position of the lamp head is changed vertically or circumferentially, the conductive wires of the existing lighting fixtures are worn due to stretching or tangling, resulting in a shortened lifespan of the wires and poor conductivity.

Method used

It adopts a structure of central shaft, support plate and bracket. The central shaft drives the lamp head and power supply components to rotate synchronously through the circumferential rotation of the support plate, which reduces the misalignment and wear of parts and enhances the stability of electrical contact.

Benefits of technology

The synchronous rotation design reduces misalignment and wear between lighting device components, improves electrical contact stability, and extends the service life of the lighting device.

Abstract

This utility model relates to a lighting device, including a central axis, a lamp head, a power supply assembly, a support plate, and a stand. The lamp head is connected to the central axis. The power supply assembly includes a main board and a power supply structure with the main board. The main board is electrically connected to the lamp head through the power supply structure. The central axis, lamp head, and power supply structure can rotate synchronously in the circumferential direction. The support plate is circumferentially connected to the central axis. The stand is connected to the support plate, and the stand and support plate can rotate synchronously in the circumferential direction. In this application, during the circumferential rotation of the central axis relative to the support plate, the lamp head and the power supply structure can rotate synchronously relative to the stand, thereby changing the circumferential lighting orientation of the lamp head. This change in the circumferential lighting orientation of the lamp head reduces misalignment, loosening, and mutual wear between the components that realize the lighting function, enhances the electrical contact stability of the entire lighting device, ensures the stability of the lighting function, and extends the lighting life of the lighting device.
