Abstract:
There is provided a vacuum envelope having at least a first substrate, a second substrate opposed to the first substrate with a predetermined distance thereto, and plural spacers positioned between the first and second substrates A ratio &eegr; is defined by S/A, in which A is the internal cross-sectional area of the vacuum envelope in a cross-section parallel to a plane of one substrate opposed to the other substrate and S is the total cross sectional area of the plural spacers on such cross section, and satisfies a relation 0.78%≦&eegr;≦7.8%.

Abstract:
A metal halide lamp includes an arc tube and a surrounding tubular quartz sleeve between a wire frame. The wire frame is formed from a pair of substantially parallel wire frame members and a top section where the two frame members meet. The two frame members are mounted to a glass stem containing current supply leads. The sleeve is provided with two pairs of diametrically opposed apertures, each pair of apertures receiving an elongate wire U-clip which engages a pinched end of the arc tube inside the sleeve and the frame members outside the sleeve. A disk having a slot is inserted over a top section of the wire frame through the slot.
