US Patent 10236627 Electrical connectors for lighting and the like

An electric light including a lamp base and lamp housing with electrical connectors that are closed by magnetic attraction when polarity is correct. The lamp base is held physically in place in the lamp housing by the magnetic attraction of two pair of magnets without the need of a threaded connection. The magnet pairs hold the lamp base to the lamp housing in a fixed orientation allowing electricity to flow through the terminals in the lamp housing regardless of whether the source of electrical current is direct or alternating, and, if direct current is the source, such as electrical current from solar cells or batteries, preserves polarity, and can deliver direct current when the light source uses direct current, such as LEDs.
