Abstract
Provided is a downlight including a back cover, a face ring, and a flexible light strip. The back cover includes a bottom surface and a first annular sidewall connected to the periphery of the bottom surface, the back cover is made of metal. The face ring includes an axially extending second annular sidewall, the first annular sidewall surrounds an outer side of the second annular sidewall and contacts an outer wall surface of the second annular sidewall, the face ring is made of plastic. The flexible light strip is fixed to an inner wall surface of the second annular sidewall. The composite structure of the metal back cover enclosing the plastic face ring fully leverages the high thermal conductivity of metal while utilizing plastic to reduce overall costs, achieving synergistic optimization of thermal performance and manufacturing costs.
