Abstract

This utility model relates to the field of lighting electrical technology, and the technical problem it aims to solve is to provide a lamp beam direction adjustment mechanism, including a heat sink, an adjustment ring, and a lens. The heat sink has a central column and a first cup-shaped arc surface. A light source assembly is located at the top of the central column. The first cup-shaped arc surface surrounds the central column. The adjustment ring is fixed to the lens. The adjustment ring has a second cup-shaped arc surface that matches the first cup-shaped arc surface and can move relative to it. The light source assembly faces the lens. In use, due to the structural cooperation between the first and second cup-shaped arc surfaces, the adjustment ring can rotate circumferentially and swing up and down relative to the heat sink, thus allowing adjustment in multiple degrees of freedom. Because the adjustment ring is fixed to the lens, the lens can rotate circumferentially and swing up and down relative to the light source assembly at the top of the central column, thereby flexibly adjusting the beam direction.
