Abstract
A lighting device such as a solid state downlight includes a lens structure with at least one integrally formed trim retaining element, and a trim structure including at least one lens structure engaging element, wherein the at least one lens structure engaging element is arranged to removably engage the least one trim retaining element, such as by rotating the trim structure. A generally cylindrical portion of the trim structure may be arranged to surround a central portion of the lens structure, thereby reducing or eliminating light piping and eliminating visible attachment elements for the trim structure.
