A lamp socket includes a first socket portion, a second socket portion, and a neck portion joining the first and the second socket portions. The first socket portion defines a first cylindrical volume proximate to an open end of the lamp socket. The second socket portion is concentric with the first socket portion and defines a second cylindrical volume distal from the open end of the lamp socket. The second socket portion has a smaller diameter than the first socket portion.

A semiconductor lamp (1) comprises a housing (2) in which a driver (3) is accommodated and at least one contact pin (6) protruding from the housing (2) outwards, wherein the contact pin (6) is tubular and riveted to the housing (2) and the driver (3) is connected to the contact pin (6) via an electrically conductive connection element (12) which is inserted into a cavity (13) of the contact pin (6). A method serves for producing a semiconductor lamp (1), wherein at least one tubular contact pin (6) is inserted into a feedthrough (5) of a housing (2) from outside till the contact pin (6) abuts the housing (2), the contact pin (6) is next riveted with the housing (2) on the inside and a driver (3) is inserted into the housing (2), whereby an electrically conductive connection element (12) is inserted into the contact pin (6). The invention is particularly applicable to LED retrofit lamps for replacing bipin halogen lamps, in particular MR16 lamps.

A device for interconnecting electrical wiring or for accessing electrical current carried by electrical wiring includes an electrical junction housing for receiving an electrical cable, an inner housing inserted into the junction housing to connect the individual wires of the incoming electrical cable to a first magnetic electrical connector carried by the inner housing. A physical interface device such as a switch or a wall socket is then wired to a second magnetic electrical connector that can be plugged into the electrical junction housing. The two magnetic electrical connectors, when joined in the correct orientation, pass electrical current.

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.

A dielectric barrier discharge lamp assembly for a fluid treatment system. The lamp assembly can include an inductive secondary, first and second electrodes coupled to the inductive secondary, and a lamp including a dielectric barrier interposed between the first and second electrodes. The dielectric barrier can define a discharge chamber including a discharge gas, and one of the first and second electrodes can extend within the discharge chamber. The inductive secondary can be adapted to receive power from a nearby inductive primary to promote a dielectric barrier discharge in the discharge chamber. The resulting dielectric barrier discharge can generate ultraviolet light for the treatment of air or water, or for other applications.
