Solid state floor lighting unit and system

摘要: A solid state floor lighting unit comprises a printed circuit board carrying an array of elements and protective cover. The cover has openings or other light output regions aligned with the to provide output. at least one edge downwardly projecting spaced supporting tabs. These tabs form comb structure which enables adjacent units be interlinked. In this way reduced pitch between across join is made possible, but still provides required stiffness robustness carry heavy loads.
