Abstract:
A lamp assembly having a lamp base and an incandescent or electrodeless gas discharge light source mounted on the lamp base. The light source includes a light-transmissive envelope having a groove extending around the envelope at one end, and this groove is used to retain the envelope in place against a mounting surface of the lamp base. The mounting surface has a plurality of fingers circumferentially spaced about a central insertion axis of the light-transmissive envelope. When the envelope is inserted into the lamp base, the fingers deflect outwardly away from the insertion axis and then return at least partially to be received in the groove of the lamp envelope. The fingers provide a radially, inwardly directed force on the lamp envelope to inhibit relative movement between the envelope and the lamp base.
Abstract:
A fluorescent lamp includes a glass envelope having a sealed end portion, an insulator disk positioned on the envelope end portion, and a collar of shrink wrap material disposed around the envelope end portion and the insulator disk, the shrink wrap material being shrunken and compressing against the envelope end portion and the insulator disk, to fix the insulator disk on the envelope end portion.
Abstract:
A light bulb assembly with reduced tolerance for engaging a light bulb to a light engine. The light bulb has a first positioning portion. The light bulb assembly has a light machine and a light bulb frame. The light machine has a second positioning portion and an engaging portion for fixing the light bulb in a determined position when the first positioning portion of the light bulb abuts the second positioning portion. The light bulb frame is relatively fixed to the light machine for supporting the light bulb; the light bulb frame has a leaning portion for leaning on the first positioning portion of the light bulb, and an elastic pressure portion for applying three-dimensional pressure on the light bulb for moving toward the determined position.
Abstract:
A mount for a fluorescent lamp has a glass base, a longitudinal electrode coil mounted upon lead-in wires extending from the base, and a shield mounted upon the base. The shield comprises a pair of spaced apart shield plates, one on either side of the electrode coil and spaced therefrom
Abstract:
A high intensity discharge lamp assembly includes a base having a tubular member and a frame is mounted to the tubular member. A plurality of position slots are defined in an outer periphery of the tubular member of the base. A lamp is engaged with the frame and a clamp member has a hole through which the lamp is inserted. A plurality of clamp plates extend from a periphery of the hole and clamp the lamp. A C-shaped clip is engaged with an annular recess of the frame and one of the position recesses of the tubular member of the base. By moving the C-shaped clip, the lamp and the frame adjustably move on the tubular member of the base.
Abstract:
An apparatus and method for compact ballast for fluorescent lamps includes a housing having an upper end, a lower end, and a side periphery extending therebetween; a threaded base extending from the lower end of the housing and comprising a plurality of base electrical contacts insulated from each other for connecting the ballast to a complementary source of electrical power; a plurality of armature windings connected in series to the plurality of base electrical contacts to thereby provide voltage and current sufficient for heating electrodes in the fluorescent lamp when the lamp is electrically connected to the ballast; and a lamp receptacle formed at the upper end of the housing and including a plurality of receptacle contacts connected to the plurality of armature windings and to the plurality of base electrical contacts so as to complete an electrical circuit with a fluorescent lamp engaged in the lamp receptacle, the lamp receptacle having a receptacle cavity extending into the housing from the upper end toward the lower end, and having the plurality of armature windings positioned about a periphery of the receptacle cavity to thereby provide compactness to the ballast.
Abstract:
A lamp apparatus for a liquid crystal display that is capable of preventing a short and a breakage of the lamp apparatus. In the lamp apparatus, a lamp generates light, and a wire supplies external electric power to the lamp. A soldering connects the lamp to the wire. A holder encloses the soldering and a lamp housing encloses the holder and the lamp. A resin in the holder seals a space between the soldering and the holder.
Abstract:
The invention relates to an electric lamp with a base on one side, having a base (4) which has a holder (5) for a lamp vessel (2), the holder (5) being provided with a stop (5a) for one end of the lamp vessel (2), and the base (4) having spring elements (3) for fixing the lamp vessel (2) in the base (4). According to the invention, the lamp vessel (2) is equipped with an annular groove (2a), and the spring elements (3) are designed such that they act on the lamp vessel (2) in the area of the annular groove (2a), so that the end of the lamp vessel (2) sits with a press fit on the stop (5a).
Abstract:
The electric lamp has a light source (20) in an outer bulb (21). The light source (20) is secured in an envelope (1) by means of an insulator body (40) in which current connection conductors (43) are integrated and which is present in a lamp cap (10) of the reflector lamp. The lamp cap (10) is mechanically connected to a neck portion (5) of the envelope (1). The integrated insulator/current connector body (40, 43) enables electrical contacting, fixation, and mechanical adjustment of the light source (20) in the envelope (1).
Abstract:
A lamp holder has a socket housing forming a seat centered on an axis, and a contact fitted to the seat and formed unitarily with a pair of opposite generally axially extending sides flanking the axis. A front finger extending generally axially from one of the sides has a pair of opposite edges and therebetween a face directed radially toward the axis and pressing the lamp contact pin transversely of the axis against the other side. A back finger extending from the other side offset laterally from the front finger has an outer edge juxtaposed with the one side. The conductive core is pinched between the outer edge and the one side laterally adjacent the front finger and bears laterally against one of the edges of the front finger.
