  • Patent number: 6585393
    Abstract: A light fixture uses printed circuit boards and is adapted to be modularly connected to other similar light fixtures to allow for any configuration of a light fixture to be provided. The light fixture may include a plurality of printed circuit boards which are removably provided in the light fixture and which simplify the manufacturing, substantially reduce the cost and size of the lighting system. More specifically, the light fixture includes a housing having first and second ends, electrical endcaps located at the first and second ends of the housing and at least one printed circuit board disposed inside of the housing and electrically connected to at least one of the electrical endcaps, the printed circuit board including a socket containing a lamp contained therein.
