Definitions
- the present invention relates to a metal vapor discharge lamp and a lighting device.
- FIG. 22 is a plan view of a base side portion of a lamp according to Modification 13;
- FIG. 33 An enlarged view of a base portion in a state where a lamp according to Modification 23 is mounted in a socket.
- the luminaire 12 includes a reflecting plate 16 that reflects light emitted from a lamp 14 disposed therein, a socket (not shown) that is incorporated in the reflecting plate 16 and to which the lamp 14 is attached, and a reflecting plate 16. And an attachment 18 for attaching to the wall or ceiling.
- the electrodes 50 and 52 are composed of electrode rods 54 and 56 and electrode coils 58 and 60 provided at the ends of the electrode rods 54 and 56 on the tip side (discharge space 38 side). And.
- the molybdenum coils 62, 64 are mounted on the electrode rods 54, 56 to prevent the luminescent material from entering the gap. Is inserted.
- the discharge tube 30 and the like described above are accommodated in an inner tube 32 having a cylindrical shape, for example, a cylindrical shape.
- the inner tube 32 is made of, for example, quartz glass, and the end portion on the side where the metal foils 78 and 80 are present is crushed by a so-called pinch seal method, and is hermetically sealed over a portion corresponding to the metal foils 78 and 80. Stopped! /
- the convex portion 90 at the tip of the other end of the inner tube 32 is a tip-off portion that is the remaining portion of the exhaust tube used when evacuating the inner tube 32.
- the reason why the inner tube 32 is evacuated is to prevent oxidation of the power feeders 66 and 68 and the power supply lines 72 and 74 that are exposed to a high temperature when the lamp is lit. From the viewpoint of prevention of acidification, the inside of the inner tube 32 (and the outer portion of the discharge tube 30) can be filled with an inert gas rather than being evacuated.
- the inner tube 32 is covered with an outer tube 34 having a bottomed tubular shape (that is, a tubular shape in which one end is opened and the other end is closed).
- the outer tube 34 is, for example, hard glass It functions as a protective tube. That is, even when the discharge tube 30 is broken and the inner tube 32 is damaged, it serves to prevent further diffusion of fragments and the like.
- the outer tube 34 has the same cylindrical shape as the inner tube 32, for example, a cylindrical shape, in order to ensure the compactness of the lamp.
- the clearance between the outer tube 34 and the inner tube 32 is, on average, lmn! To ensure clearance when the outer tube 34 is covered on the inner tube 32 during the assembly process. ⁇ 2mm.
- a regulating member 37 is provided in the distal end portion of the outer tube 34, that is, on the side opposite to the base 36.
- the regulating member 37 is inserted in advance into the outer tube 34 when the discharge tube 30, the inner tube 32, the outer tube 34, and the like are assembled.
- the restricting member 37 expands radially with respect to the tube axis of the inner tube 32 as the inner tube 32 is inserted. Now comes in contact with the inner surface of 34!
- FIG. 4 is a perspective view of the regulating member 37.
- the regulating member 37 includes an annular portion 92 formed in an annular shape having end portions 92a and 92b that overlap each other in the circumferential direction (for example, in the direction of arrow B) and smaller in diameter than the outer diameter of the inner tube 34, and the annular portion 92 includes And a support portion that supports the lamp shaft so as not to move in the extending direction of the lamp shaft (this direction is referred to as “lamp axis direction”).
- the annular portion 92 is formed in an annular shape in a state where the end portions 92a and 92b overlap with each other. Therefore, when the inner tube 32 is inserted into the annular portion 92, the end portion is associated with the insertion. 92a and 92b are shifted from each other in the circumferential direction, and the annular portion 92 is expanded in diameter.
- the extending portion 97b that is connected to the annular portion 92 and is not on the side extending from the annular portion 92 is only in contact with or in proximity to the annular portion 92, and is joined to the annular portion 92. Absent.
