Abstract: An apparatus for making electrical contact with luminous means in spotlights, which contain a glass vessel, a luminous means base and contact pins for the power supply is provided. The apparatus comprising a luminous means holder with at least two socket pairs for accommodating the contact pins of different luminous means. The socket pairs are arranged in clamping pieces, whose mutually opposite connecting faces can be removed from one another in order to accommodate the contact pins of the luminous means and can be guided towards one another in order to make electrical contact with the contact pins of the luminous means.

Abstract: A lamp socket assembly includes a base plate, and lamp sockets, each lamp socket including a connection terminal, each connection terminal connected to a terminal of a lamp, and one or more first fixing portions, each of which is integrated with the connection terminal, penetrates the base plate, has at least one bent end, and contacts opposing surfaces of the base plate.

Abstract: An electrical connector with a first coupling device with a first connection for a first electrical cable and a second coupling device with a second connection for a second electrical cable and wherein both coupling devices are interlocking for electrical contact. The second coupling device includes a first component to contact the first coupling device by interlocking, a second component that includes the second connection, and a coupling device for electrical coupling of the first component with the second component, wherein both components are flexible relative to each other in radial and/or axial direction.

Abstract: An electrical mounting connector for a bi-pin fluorescent bulb has a lamp holder with two terminals and a cap with two pin guiding openings that snaps into the lamp holder such that two pins held in the two pin guiding openings will be held in contact with the two pin-shaped over a substantial portion of the pins along a parallel length of the pins. An alignment marking is provided on the lamp holder and a visual inspection point (such as a hole) is provided on the cap that compliment one another to provide a visual indication of when the lamp holder and the cap are properly assembled together. A drain is formed by one or more slots in the lamp holder to drain a space between the lamp holder and the cap accessed through pin guiding openings when the lamp holder and the cap are properly assembled together.

Abstract: A device for rapid installation of a lamp provides easy connection for a plurality of fluorescent tubes to a connecting box. Each of the fluorescent tubes is mounted into a base frame where a slide rod on a sliding track thereof secures the insertion of a fluorescent tube. As a fluorescent tube is inserted into the base frame, a slopped upper surface at the end thereof pushes the slide rod inward and upward. The slide rod, pushed by the fluorescent tube to the higher end of the sliding track, departs from a higher side of the slopped upper surface, slides back to the lower end of the sliding track, and thereby steadily holds the fluorescent tube. To unplug a fluorescent tube, the slide rod is pushed over the higher end of the sliding track so that the base frame and the fluorescent tube are unlocked.
