A high-brightness LED lamp bead

Abstract

A high-brightness LED lamp bead, belonging to the field of lighting technology, is disclosed. This device addresses the problems of insufficient heat dissipation affecting the lifespan of existing LED lamp beads and the inability to adjust the illumination angle. It includes a recessed top of the base housing an adjustable mounting shell with an adjustment gap between them. A rotating ball is embedded in the bottom of the mounting shell, engaging with a sliding post within the base. The sliding post is spring-loaded for elastic fixation, ensuring the stability and adjustability of the mounting shell. Multiple heat dissipation fins are located on the bottom of the substrate, a second heat dissipation hole is formed at the bottom of the mounting shell, and first heat dissipation holes are formed around the base to create multi-directional heat dissipation channels. The inner wall of the mounting shell is covered with a reflective coating, and the top is press-fitted into a removable lampshade's annular groove via an extension. This device achieves adjustable illumination direction through its adjustment structure. Combined with a multi-stage heat dissipation structure and optical reflection design, it improves heat dissipation efficiency and operational stability while maintaining high brightness output, making it suitable for lighting scenarios requiring directional lighting and long-term operation.
