Abstract: A lamp includes a bulb; a light source such as an LED; a lamp base including a connector for providing electricity from a standard lamp socket; and a housing coupled to the lamp base and supporting the bulb in a position to receive electromagnetic energy from the light source. Circuitry connected to receive electricity from the connector of the lamp base provides drive current to the light source. In the examples, each of the lamps also includes a theft deterrence mechanism coupled to the lamp base configured to deter unauthorized removal of the lamp once the lamp base has been inserted into the standard lamp socket to enable lamp operation.

Abstract: A lamp holder connector includes a lamp box and at least one pair of lamp bases assembled to the lamp box. The lamp box includes a first upper holder, at least one pair of first lower holders assembled to the first upper holder, and at least one pair of first terminals received in the lamp box. Each side of the first upper holder defines an elastic portion. An outer face of each elastic portion defines at least one fastening portion. Each lamp base includes a second upper holder assembled to the first lower holder, a second lower holder assembled to the second upper holder, and a second terminal received in the second lower holder. At least one side of the second upper holder defines a receiving groove for receiving the elastic portion. A sidewall of the receiving groove defines at least one fastening hole for buckling the fastening portion.

Abstract: In a discharge tube, a conductive ferrule is provided on an end portion of a glass tube. The ferrule includes a body that is to be mounted to the outer circumference of the glass tube and has a contact portion to be electrically conductively fixed to a relay connector (or a bearing device). Further included is a conductive portion that extends from the body so as to have elastic contact with an outer lead. The outer lead will not be under load due to the weight of the discharge tube, but the conductive portion solely has elastic contact therewith. Thus, stress concentration on the outer lead can be prevented.

Abstract: A lamp has a polygonal-section plug part extending along an axis and having at least one radially outwardly directed face formed with a radially outwardly projecting retaining bump. A socket has a core body formed with a polygonal-section socket hole complementary to the plug part and into which the plug part can be fitted axially in an installed position and that substantially completely prevents angular displacement of the plug part relative to the core body in the installed position. A sleeve surrounds the core body and can angularly shift relative thereto between a freeing end position and a blocking end position. The sleeve is formed with a radially inwardly projecting retaining formation that, in the installed position of the plug part, is angularly offset from the bump in the freeing position and that operatively engages and blocks axial displacement of the bump in the blocking position.

Abstract: The present invention relates to a low-pressure discharge lamp (1) including a discharge tube (20) and a base (5) providing for mechanical and electrical connection of the discharge lamp (1). The discharge tube (20) sealed in a gas-tight manner at its both ends is bent substantially in one plane so that the discharge tube (20) has straight (2) and arc-shaped portions (3), and the base (5) connected to the ends of the discharge tube (20) includes at least cathode leads of the discharge tube (20) and electrical connectors (15) connected to said leads. At least one component ensuring mechanical connection to a lampholder is formed on the base (5). The components of the discharge lamp (1) ensuring mechanical connection to the lampholder (16) are placed in a space bordered by the discharge tube (20). A lampholder (16) of the discharge lamp (1) includes components ensuring electrical and mechanical connection to the discharge lamp (1).

Abstract: An adapter (1) for a discharge lamp which comprises a socket portion (3) and a plug portion (5). The socket portion is suitable for receiving electrical contacts of a first discharge lamp which includes a discharge tube disposed substantially in a planar zone having a principal plane. The socket portion has an associated socket contacting plane where the socket contacting plane is defined as the principal plane of the discharge tube of the first discharge lamp when the latter is inserted into the socket portion. The plug portion is insertable into an external female socket which is suitable for receiving a second discharge lamp including a planar tube configuration. The plug portion also has an associated plug contacting plane. This plug contacting plane is defined as the principal plane of the tube configuration of the second discharge lamp when this latter is inserted into the external female socket. The adapter further comprises a connecting portion for connecting the socket portion and the plug portion.

Abstract: A lamp assembly mount is adapted to receive a specific commercially available fluorescent lamp known as the "2D" lamp, which is commercially produced in several different sizes and commensurate wattage ratings. By taking advantage of certain structure in the design of the 2D lamp that is specific to its wattage rating, the lamp assembly mount will only receive the correct lamp, eliminating the possibility of mounting under-or over-wattage fluorescent lamps of different base configurations.

Abstract: A lighting device has a single end lamp in which a base is disposed at one end of a bulb, and a single end lamp socket into which the base is to be inserted and then twisted to be rotatively engaged with the socket. The lamp has a projection and a lamp pin both projected from a bottom of the base, the tip end of the projection being further projected from the bottom of the base than the tip end of the lamp pin. The socket has a recess into which the projection of the lamp is inserted and rotated by a predetermined angle, as well as a lamp pin insertion hole positioned outside of the recess and concentric with the recess, and having a substantially arcuate shape. A conductor plate which elastically makes contact with the lamp pin is disposed in the lamp pin insertion hole.

Abstract: A compact fluorescent lamp is provided having a generally helically shaped lamp envelope wherein the two end segments of the lamp envelope extend radially inward from the pitch of the helix. The end segment extend into openings formed in a mounting cap member which is essentially dome-shaped at the center portion thereof. The mounting cap member can be constructed of two pieces each of which accepts one of the end segments of the lamp envelope. The mounting cap member is effective for reducing the amount of lamp envelope surface area that must be disposed within the housing of the lamp and is further beneficial in that light generated on the inside surface of the lamp can be reflected outward and more readily escape without losses due to multiple reflections or absorption.

Abstract: A conduit sealing assembly for sealing a conduit for carrying high voltage wiring from a neon tube through a backing panel of the neon display includes a hollow connector member for securing to the backing panel so as to project through an opening in the panel. One end of the connector member on the rear side of the panel is secured to a conduit for guiding the wiring from the panel for connection to a power supply. A hollow sealing plug is secured in the opposite end of the connector member, and a hollow insulating tube for guiding wiring from the neon tube through the backing panel has one end inserted into the connector member through the plug member, which seals against the surface of the tube to provide a weather proof seal.

Abstract: To permit easy insertion and removal of a compact fluorescent lamp (2) in and from a socket, the socket is formed with a body (3) having an engagement surface wall (5) from which a shelf (4) projects bounded by side walls (22, 23) to define a base reception cavity (25). The engagement wall (5) is formed with slits (11) to permit terminal pins (13) from the lamp to pass therethrough, for engagement with electrical terminal contacts (T). The lamp is held in position by a resilient catch or latch or snap-over element (14) movably mounted on the engagement wall (5), for example by being molded on a separated strip portion (15) forming a resilient holder, and projecting from the engagement wall (5), to snap over the end portion of a base (35) of the lamp, when inserted. To release the lamp, the catch can be bent backwardly. Holding projections (30) on the shelf lock the lamp in position.
