Abstract
An adapter plate is provided that fits an existing luminaire in place of an existing globe that mounts to the luminaire. A heat sink mates to the adapter plate and also houses a solid state light engine and associated electronics. The heat sink may provide an enclosed, protective volume for the associated electronics, such as a power supply for the solid state light engine. A globe mounting ring attached to the heat sink allows either an existing globe to be re-mounted or a new globe to be installed.
Claims20
A solid state light fixture, comprising:
- an adaptor plate that is adapted to be secured to a base to which the light fixture is to be mounted;
- a heat sink adapted to be secured to said adaptor plate, said heat sink comprising a light engine mounting surface and a globe adaptor ring mounting surface on a first side thereof, and a plurality of heat dissipating elements on a second side thereof;
- a light engine mounted to said light engine mounting surface;
- a power supply mounted to said second side of said heat sink that is electrically connected to said light engine;
- and
- a globe adaptor ring adapted to be secured to said globe adaptor ring mounting surface, said globe adaptor ring adapted to receive an optically transmissive globe that encloses said light engine, and
- when said adaptor plate, heat sink, and globe adaptor ring are secured together, said heat dissipating elements provide a thermally conductive path between said heat sink and ambient air outside of the globe.
A system for securing a solid state light fixture to an existing light fixture pole having an existing mounting structure for an existing optically transmissive globe, comprising:
- an adaptor plate that is adapted to be secured to the existing mounting structure;
- a heat sink comprising a light engine mounting surface and a globe adaptor ring on a first side thereof, and a plurality of heat dissipating elements on a second side thereof, said heat sink adapted to be secured to said adaptor plate;
- a light engine mounted to said light engine mounting surface;
- and
- a power supply mounted to said second side of said heat sink that is electrically connected to said light engine and adapted to be electrically connected to a utility power source;
- said globe adaptor ring adapted to receive an optically transmissive globe that encloses substantially all of said first side, and when said adaptor plate and heat sink are secured together to the existing mounting structure, said heat dissipating elements provide a thermally conductive path between said heat sink and ambient air outside of the globe.
