Abstract: The inventive concept is directed to shock free bulb socket that is inserted in an existing light bulb socket to forego any possible electric shock when there is no light bulb in the existing bulb socket and the electric switch happens to be in an “on” status. The insert socket is a housing that is placed over the existing socket and fastened thereto. The insert socket consists of a lower threaded segment that is threaded into the existing socket. There is an upper threaded segment that will receive the light bulb. When the light bulb is threaded into the upper segment it will encounter a plate there below and will cause the upper threaded segment to slide upwardly together with a bracket to which it is attached. There is a sliding hot prong and a sliding neutral prong which will make contact when the bracket moves upwardly and will convey electric current to the light bulb.

Abstract: A GU24 3-way dimmer knob-type switch lamp holder is disclosed, where the body of the lamp holder is provided with three contact plates at the two sides of its interior and on its bottom. And an insulating rotor and a rotor conducting plate therein is driven by a knob. The rotor conducting plate is shaped into four portions along its rim, where three of them come with a shaped contact plate, while the fourth is void. The insulating rotor and the rotor conducting plate are driven to rotate by turning the knob, which enables three contact plates in the body and three contact plates of the rotor conducting plate to form no conduction or different conduction modes that enable various levels of illumination: dim, moderate and high brightness after power ON and feature power OFF as well.

Abstract: A lighting system that includes a light bulb having a threaded bulb base and a luminare socket. The bulb (200) includes a two conductor base (201, 205) while the luminare socket (300) utilizes a circular ring (305) with an open aperture (307) for supplying current to the bulb. The circular ring (305) and aperture (307) in the luminare socket are sized to provide contact with the center contact (205) of the light bulb when the preferred wattage is selected. This prevents over wattage light bulbs from being used avoiding excess heat, arcing and the potential for fire.

Abstract: Improvements to a 3-way light bulb socket are shown. The major improvement is to replace or complement the rigid middle contact element of the socket with an elastic/flexible contact spring. The 3-way light bulb has a solder blob on its middle contact ring, where said blob usually has a rough, uneven surface, and frequently does protrude beyond the general surface of the bulb middle contact ring. The solder blob interferes with the conventional socket middle contact element, which is rigid, and prevents the system from creating a good, permanent and reliable electrical connection between the socket and the bulb. Potential flicker and discomfort to the user can occur as a result. Also, the operating life of the bulb as well as the power consumption can be affected. The proposed flexible middle contact spring can alleviate most of these problems.

A lamp lacking such an extension and a contact on such extension, cannot extend into and engage the contact in the cavity.

Abstract: Improvements to 3-way light bulbs and to their electrical sockets are shown. The major improvement is to replace the rigid middle contact element of the socket by an elastic contact spring. Other improvements are described, which can be applied to the bulbs as well. These include flattening and smoothing the solder joint that is located on the bulb middle contact ring. Also, some new add-ons inserts or adapters are described, which can be used together with the bulbs and sockets, to improve the performance of such bulbs.
