摘要： 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.

摘要： 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.

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.

摘要： 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.

摘要： An arc tube having a closed glass bulb having no broken-off portion, and a method of manufacturing the arc tube. A glass bulb is formed on a glass tube substantially at the middle. An electrode assembly is inserted into one end portion of the glass tube, and the one end portion is closed by pinch-sealing. A light emitting material is supplied into the glass bulb through the other end portion of the glass tube, another electrode assembly is inserted into the other end portion, and the latter is closed by pinch-sealing. Since the closed glass bulb has no broken-off portion, the arc tube is free from the difficulty that the distribution of light is adversely affected. Moreover, in manufacturing the arc tube of the invention, it is unnecessary to connect an exhaust tube to the glass tube. Therefore, the number of manufacturing steps is small, and the arc tube can be manufactured with ease.

摘要： In the manufacture of arc tubes for use as light sources of vehicle headlamps, there is first prepared a semifinished arc tube by inserting one electrode assembly into a tubular glass envelope through one end thereof and by sealing this end. The semifinished arc tube is then placed in communication with a hermetically enclosed space filled with argon under pressure, with the consequent introduction of the inert gas into the glass envelope through a second end thereof. Another electrode assembly and chemicals such as a metal halide and mercury are then introduced from the enclosed space into the semifinished arc tube through the second end, totally without contact with the atmospheric air. Then, with the glass envelope placed out of communication with the enclosed space, the argon is exhausted from within the envelope, and xenon is charged instead into the envelope through the second end, which is closed subsequently.

摘要： A method of manufacturing an arc tube for a discharge lamp unit, incorporating a primary pinch-sealing step for mounting an electrode assembly in an open end of a glass tube W with a chamber portion 12. The electrode assembly comprises an electrode rod 6, a connecting foil 7 and a lead wire 8 integrally connected in series. The electrode assembly is inserted into an open end of the glass tube W such that a leading end of the electrode rod projects into the chamber portion 12. A temporary pinch seal region L1 of the glass tube W is pinch-sealed such that a portion of the connecting foil that is connected to the lead wire is contacted by the glass tube W. A vacuum is maintained inside the glass tube and a main pinch seal region L2 of the glass tube is pinch-sealed such that a portion of the connecting foil connected to the electrode rod is contacted by the glass tube. When the main pinch seal region L2 of glass tube W is pinch-sealed, the negative pressure in the glass tube W is exerted on the softened sealed chamber portion 12 owing to supplied heat as well as the pressure exerted from the pincher 26b. Thus, the glass layer 15 is pressed against the surface of the molybdenum foil 7 so that hermetic contact is realized.
