摘要： PURPOSE:To obtain a fluorescent lamp lit with the low power source voltage and having excellent luminous efficiency by providing an electrode having at least one kind of material selected BaO, SrO, CaO, MgO, LaB6 on the inner face of the hollow electrode. CONSTITUTION:An electrode 3 is formed into a hollow shape, and at least one kind of material selected out of BaO, SrO, CaO, MgO, LaB6 is provided on the inner face of the hollow. These materials are not reacted with mercury and operated stably. If the rare gas pressure is set in the range of 400/M-4000/M Torr, where M is the atomic weight, the cathode drop voltage is particularly decreased in this range. A lamp can be thereby lit with the low power source voltage, and a high efficiency is obtained.

摘要： PURPOSE:To automatically mount a pellet to a fitting plate having warpage and improve efficiency of pellet mounting by executing the pellet bonding while causing pitching and rolling to pellet. CONSTITUTION:A pellet 1 consisting of silicon providing the gold depositing layer at the lower surface is absorbed and held by the collet 2. The bonding arm 3 supporting the collet 2 is vibrated in the direction of the plane orthogonally crossing the axial direction 4 and is rolled to the vibrating direction. Thereby, the pellet 1 is fixed to the fitting plate 5 having the Au depositing layer at the surface. As a result, the pellet 1 is shifted repeatedly for the angle + or -alpha for the longitudinal direction by the rolling. Accordingly, the entire part of lower surface of pellet 1 is sequentially and repeatedly rubbed within a short period of time and thereby the eutectic alloy layer of Au-Si is formed at the entire part of interface between the pellet 1 and fitting plate 5, forming the good connection.

摘要： PURPOSE:To intend the efficient use of infrared rays by having an anchor and a pair of internal leads buried in a glass bead and fixed in a quartz glass tube, on the outside surface of which an infrared reflecting film is formed, arranging a filament in parallel to the tube axis of the quartz tube and providing infrared reflecting plates on both ends of the filament. CONSTITUTION:There is a composition of a filament 1, internal leads 2, 2', molybdenum foils 3, 3', external leads 4, 4', a base 5, a quartz bulb 6, a bead 7, a cooling fin 8, an anchor 9 and infrared reflecting plates 10, 10. Infrared rays emitted from the filament 1 are reflected by the infrared reflecting plates 3, 3' formed on the bulb 6, and part of that is returned to the filament 1 and the remainder is reflected by the filament 1 or passed by the filament 1 and then reflected again by the infrared reflecting plates 3, 3' but returned to the filament 1 some time because of a blocked infrared outlet. It is thus possible to intend the efficient use of infrared rays.

摘要： PURPOSE:To obtain a direct current discharge lamp having a stable anode which is durable against heat generation from the initial stage of lighting to the terminal period of the service life by using a specified anode. CONSTITUTION:When the relation of the material and wire diameter of an anode 2 to electric power consumed in a light emitting tube 8, that is lamp electric power W1, is not kept properly, sometimes the anode can not bear the load and is melted and deformed within a short period during lamp operation or the material of the anode is evaporated due to high temperature and the surface is damaged and thus normal and stable lamp operation can not be maintained and characteristic of the lamp is widely deteriorated. In the case that the wire diameter D (phimm), thermal conductivity B (Wm .K ) at 300 deg.C, lamp electric power WL (W) of the anode 2 are so defined as to satisfy the relation I, the performance of the anode 2 during lamp operation is stabilized. In this way, without unstabilizing the performance due to deformation of the anode 2 or surface break of the anode 2 during lamp operation, stable lamp performance can be obtained.

摘要： PURPOSE:To obtain a uniform and reliable halogen lamp by providing an exhaust system for exhausting and degassing a lamp and a exhaust pipe system for exhausting the sealed gas left in a gas guide system after chipping off the lamp as separate systems. CONSTITUTION:A halogen electric lamp 1 is moved to a gas guide head N after being exhausted and degassed. The preset gas is introduced through exhaust/gas guide pipes 2 and 3 in the head N, and a chuck/switch valve 5 is closed. The electric lamp 1 is then immersed in liquid nitrogen filled in a heat insulating container 6. The electric lamp 1 cooled sufficiently is moved to the next head N+1, and it is chipped off by a burner 8 while being held by a holder 7. The guide gas containing halogen gas left in the pipe 2 is exhausted at the head N+2 via a separate exhaust system, then the pipe 2 is removed while inert gas is introduced to the atmospheric pressure. The exhaust gas exhausted at the head N+2 and containing halogen is guided to a specially arranged halogen processing device and made nonpoisonous.

摘要： PURPOSE:To realize a uniform and highly reliable lamp at low cost by a method wherein mixed gas of inactive gas with halogen gas is fed and a lamp is cooled after the inlet system is closed while the lamp is held by a pre-cooled holder to be chipped off. CONSTITUTION:Sealed gas is fed into a lamp 1, and then after the inlet system is closed, the lamp 1 is cooled. Then the lamp 1 is held by a pre-cooled holder 7 to be chipped off. Thus the lamp is cooled by the pre-cooled metallic holder 7 having large heat capacitance and covered by a heat-resistant cloth-like member so that increase in temperature on the lamp part 11 can be suppressed to the degree that no problem occurs. Thus fluctuation in pressure of the sealed gas can be eliminated and accompanying fluctuation in performance can be suppressed thereby realizing a uniform and highly reliable halogen lamp.
