A method is provided for formation of a glass to metal seal at one end of a quartz lamp tube, as part of the process of manufacturing a complete lamp tube. The method involves a direct sealing of the tube of quartz glass with a seal material surrounding an electrode or its electrical feed through. The seal material may be in the form of a bead having a generally elliptical or spherical shape.

A low-pressure mercury vapor discharge lamp has a light-transmitting discharge vessel (10), enclosing, in a gastight manner, a discharge space (11) provided with a filling of mercury and a rare gas. The discharge vessel (10) comprises means (41a) for maintaining a discharge in the discharge space (11). At least a part of an inner wall of the discharge vessel (10) is provided with a protective translucent layer (16). According to the invention, the discharge vessel (10) is provided with a pinched seal (20). In addition, the translucent layer (16) comprises a borate and/or a phosphate of an alkaline earth metal and/or of scandium, yttrium or a further rare earth metal. Preferably, the glass composition is made from a sodium-rich glass including the following constituents: 70-75 wt. % SiO2, 15-18 wt. % Na2O, 0.25-2 wt. % K2O. The discharge lamp according to the invention has a comparatively high maintenance.

A mount assembly (10) for a lamp that comprises a light source (12) having two ends (14, 16) separated by a hollow middle portion (18). Light source capsule (12) can be an arc discharge vessel and the ends (14) and (16) are substantially parallelepipedial. The ends (14) and (16) are also provided with alignment segments (60) in the form of spaced apart beads (62) and (64). A metal strap (20) surrounds one of the ends, for example, (14), and is positioned between the beads (62) and (64), and has first and second oppositely disposed affixation areas, (22, 24); which can be in the form of extensions (22a) and (24a). A glass stem (26) has a tubular first portion (28) with an outside diameter D. A substantially C-shaped clip (30) is mounted upon the tubular first portion (28). The C-shaped clip (30) has a given height H and an inside diameter D1 that is smaller than the outside diameter D whereby the clip frictionally engages the tubular first portion. A first frame member (32) has a proximal terminus (34) affixed to the substantially C-shaped clip (30) and a second frame member (35) has a proximal terminus (36) affixed to the substantially C-shaped clip (30) opposite the first frame member (32). The first frame member (32) has a distal terminus (38) affixed to one of the affixation areas on metal strap (20), for example, area (22), and second frame member (35) has a distal terminus (40) affixed to the other of the affixation areas, for example (24). The first and second frame members (32) and (35) and the metal strap (20) constitute the sole support for the light source (12).
摘要:
In order to provide a light emitting lamp that makes it possible to control the light emitting lamp to be at a target temperature, for a light emitting lamp including a valve portion 2 and sealing portions 3a and 3b, a quantity of power-consumption-dependent heat losses due to convection and conduction of the valve portion 2, the inside diameter of the valve portion 2, and the diameter and the length of the sealing portions 3a and 3b are determined in advance, and the outside diameter of the valve portion 2 is determined on the basis of these quantity of heat losses, inside diameter of valve portion, diameter, of sealing portions, and length of sealing portions, so that an average value of inner temperatures of the light valve portion 2 at the time of luminescence falls within a range from 900 to 1000° C.
