摘要:
An insulating base for a discharge lamp device which provides good insulation between a lead support connected to a front end lead of an arc tube and a lead disposed on the rear side of the arc tube. The insulating base includes a base main body formed of synthetic resin. The base main body is a disk-shaped injection molding which includes a lead support insertion hole in the form of a first longitudinal through hole for mounting a lead support supporting the front end portion of an arc tube and acting as a current path to a lead disposed on the front side of the arc tube, and a lead insertion hole in the form of a second longitudinal through hole for insertion of a lead disposed on the rear end side of the arc tube. The base main body is molded in such a manner that a separation wall area between the lead support insertion hole formed in the front surface of the base main body and the lead insertion hole faces molten resin injection gates provided in base main body molding metal molds, thereby preventing a weld portion from being produced in the separation wall area between the two holes.

An electrical discharge lamp device in which an ultraviolet filtering globe tightly encloses a sealed glass bulb of an arc tube containing a pair of oppositely disposed electrodes to thereby form a unitary body. The rear end part of the arc tube extending from the ultraviolet filtering globe is supported by an insulating base, and the forward end part of the arc tube is supported by a lead support extending forward from the insulating base. An extending part is formed on the front face of a base main body made of synthetic resin, and the rear part of the ultraviolet filtering globe is supported by the tubular extending part. In this construction, stress is not concentrated on the portion of the arc tube supported by the base main body of the arc tube, and hence the durability of the arc tube is improved.

A discharge lamp apparatus in which an insulating base for supporting a lead support base end portion maintains its dielectric strength over long periods of use, and which is simple to assemble. A lead support acting as a current path is projectingly provided on a front surface of a synthetic-resin insulating base, which is a lamp holder, a front end portion of an arc tube, which is a discharge lamp body, is supported by the lead support, a rear end portion of the arc tube is fixedly supported in an engagement concave portion formed in the insulating base, and the lead support is covered with a ceramic insulating cylindrical body. In accordance with the invention, a base end portion of the insulating cylindrical body is integrated with the insulating base through insert molding.

A sealed beam lamp assembly, suitable for use as a motor vehicle headlight, has an incandescent lamp mounted within an inert-gas-filled, molded-glass housing integrally comprising a reflector and a control-lens cover. For supporting the lamp in position within the housing, a metal-made support rod extends forwardly from one of ferrules on the reflector and has its front end preformed into the shape of a U to provide a rearwardly directed fold. Welded to this fold of the support rod is a metal band rigidly encircling the base of the lamp. The lamp position relative to the reflector is therefore adjustable as required by manually turning the fold of the support rod about its main straight portion. The support rod serves also to provide electrical connection between the ferrule and one of the lamp leads.

A discharge lamp device having an insulator base made of a synthetic resin integrally bonded to a globe holding member made of ceramic wherein a discharge lamp is attached. Also provided is a pair of lead supports for supporting the discharge lamp at its opposite ends. The discharge lamp and lead supports are completely surrounded by an ultraviolet ray shielding globe which is fixed to globe holding member. The globe effectively absorbs harmful ultraviolet rays having a wavelength in a predetermined wavelength range.

An electric discharge lamp assembly including a lamp bulb having two lead wires, and a lamp base supporting two lead support members with respective tip ends thereof being connected respectively to the lead wires of the lamp bulb. One of the lead support members is formed to have an elongated length and is covered by an insulating tubular member substantially. The rear end portion of the insulating tubular member is fitted on and secured to a tubular portion of the lamp base which portion is integrally formed with the lamp base. Whereby the electric discharge between the two support members is prevented effectively, and the insulating tubular member is secured to the lamp base reliably.

A discharge lamp has a lamp assembly including a discharge lamp unit with a pair of lamp leads extending therefrom, and a base assembly including a pair of base leads electrically connected to the pair of lamp leads and mechanically supporting the lamp unit in position with respect to the base assembly. The base assembly comprises a hollow base structure of electrically insulating material molded in one piece with a partition dividing the interior thereof into a pair of completely isolated spaces. Electrically connected to the base leads, a pair of sheet metal conductors are received with clearances in the respective isolated spaces in order to preclude the possibility of an electric discharge taking place between the pair of conductors within the base structure.

In a glow plug configured such that a metallic, tubular member having a heater fixedly provided therein is joined to a metallic shell, an external-thread portion is formed on the outer circumferential surface of the metallic shell so as to allow the glow plug to be screwed into a plug-mounting hole formed in an engine head. An annular protrusion is formed on the outer circumferential surface of the metallic, tubular member in such a manner as to protrude radially outward, to annularly extend in the circumferential direction, and to be located in the vicinity of a distal end of the metallic shell. A distally-facing end face of the annular protrusion abuts an annular seat face in the mounting hole, and the metallic, tubular member and the metallic shell are joined such that a distal end face of the metallic shell abuts a rearward-facing end face of the annular protrusion.

In a glow plug controller, a glow plug 10 fixed to an engine 30 comprises a heater 4 and a ceramic substrate 2 having an exposed portion 2d which is exposed to the interior of a combustion chamber 32. A glow plug control apparatus 100 causes ECU 105 to control the energization of the heater 4 of the glow plug 10 to keep the surface temperature Ts of the exposed portion 2d to not lower than 500° C. Further, ionic current Ii is measured using the glow plug 10. Switches 102 and 103 switch from the energization of the glow plug to the detection of ionic current or vice versa in response to a command signal from ECU 105.
