MODULAR LIGHTING SYSTEM AND METHOD EMPLOYING LOOSELY CONSTRAINED MAGNETIC STRUCTURES

摘要

A lighting system including modules containing LEDs or other electroluminescent devices and loosely constrained magnetic structures at least partially contained within cavities in the module substrate that are connected to fixtures under magnetic force. The loosely constrained magnetic structures accommodate mechanical variations in the system and provide a method to connect modules mechanically, electrically and thermally to different fixtures or positions in fixtures without tools. The relatively short distance separating magnetic structures provides high connection forces with the use of relatively small magnets. Magnets and electrical contacts are not located directly between the LED subassembly and the fixture, which provides higher thermal conductivity pathways to remove heat from the LEDs. Biasing members may be used to increase thermal contact. Magnetic structures may, but are not required, to conduct electricity. Fixtures that attach to modules include rails, sockets, heat sinks and two-dimensional structures with recessed electrodes for improved electrical safety.

1. A system comprising:
a) a module comprising one or more electrically powered elements that radiate electromagnetic energy; b) a thermal conduction pathway for removing heat from the one or more elements that radiate electromagnetic energy; c) a fixture for attaching a module comprising electricity and one or more electrical connections for powering the one or more elements that radiate electromagnetic energy; d) a magnetic connection between the module and the fixture for attaching; e) wherein the electricity is delivered to the one or more elements that radiate electromagnetic energy when the module is connected to the fixture via the magnetic connection; f) wherein a thermal conduction pathway is formed between the module and the fixture when the module is connected to the fixture via the magnetic connection; and g) wherein the thermal conduction pathway between the module and the fixture does not essentially pass through the one or more electrical connections.
