  • Patent number: 8063566
    Abstract: An object of the present invention is to provide an illumination apparatus which includes an illumination fixture having an open-type reflector and a metal halide lamp, and can suppress a decrease in intensity and occurrence of glare. The illumination apparatus includes a metal halide lamp and an illumination fixture. The metal halide lamp includes an arc tube which has therein a pair of electrodes, an inner tube which houses the arc tube and has a pinch seal part at one end, and an outer tube which houses the inner tube and has a base at one end. The illumination fixture includes a reflector having a concave reflecting surface, a socket, and an attachment. In the inner tube, a diffusing part which diffuses light emitted from the arc tube is formed in an area closer to a lower end of the inner tube than a center between the pair of electrodes.

  • Patent number: 7990035
    Abstract: With regard to a metal vapor discharge lamp with a triple tube structure including a discharge tube, an inner tube, and an outer tube, misalignment of axes of the inner tube and the outer tube is prevented. The metal vapor discharge lamp (14) is composed of a discharge tube (30) having a pair of electrodes therein, an inner tube (32) having a pinch-sealed part (86) at an end thereof and hermitically housing the discharge tube therein, and an outer tube (34) housing the inner tube therein, and a base (36). In a clearance between the inner tube and the outer tube, there disposed a restrain member (37) for restraining movement of the inner tube relative to the outer tube in a direction orthogonal to an axis of the metal vapor discharge lamp.

  • Publication number: 20080224615
    Abstract: The arc tube 3 comprises: a translucent ceramic envelope 19 including a central tube 16 having an inner diameter of 5.5 mm or more, thin tubes 18 formed, on contact with joining portions 17, onto both ends of the central tube 16, and at least one rare earth halide enclosed therein; and electrode inductors 24 and 25 inserted and sealed in the thin tubes 18. In a cross section of the arc tube 3 along a plane including the axis X in the longitudinal direction, an angle ? between the straight-line section of the inner surface of the central tube 16 and that of each joining portion 17 is set to 85°-115°. Clearance gaps 26 are formed between the thin tubes 18 and electrode inductors 24 and 25. The curvature radius of the inner surface of each boundary region 20 between the central tube 16 and joining portions 17 is set to 0.5 mm-2.5 mm.
