Abstract

A lighting device comprises, or consists essentially of, a housing, a solid state light emitter and conductive tracks. The conductive tracks are positioned on the housing and are coupleable with a power supply. The conductive tracks comprise a positive conductive track and a negative conductive track. Each of the solid state light emitters is in electrical contact with a positive conductive track and a negative conductive track. Another lighting device comprises a fixture and a solid state light emitter in which the fixture comprises conductive elements which are coupleable to at least one power supply and the solid state light emitter is mounted on the fixture. There is also provided a lighting device which provides light of an intensity which is at least 50 percent of its initial intensity after 50,000 hours of illumination.
