摘要： A short arc lamp in which welding of a cathode to a conductive support component yields an advantageous connection of the cathode to the conductive support component in which the thermal influences are reduced, and in which the cathode tip does not move. The short arc lamp has a body within which a concave discharge space is formed, an anode and a cathode are located in the concave discharge space, a conductive support component for supporting the cathode is connected to a feeding ring which is located in the vicinity of an open end of the reflection surface, a first metal component which is formed on one end of the body, and a second metal component which is formed on the other end of the body. In a preferred embodiment, only a single conductive support component is welded to the cathode.

摘要： A method for producing a fused silica envelope for use in a discharge lamp in which the inner surface of a fused silica tube is coated with a formulation containing titanium alcoholate and the coating treated by the steps including baking at a temperature of at least 1720.degree. C. to cause TiO.sub.2 to diffuse into the tube. The method results in a Ti concentration in a range of 1 .mu.m-10 .mu.m from the inner surface of the wall of the envelope is 0.5%-7% in terms of TiO.sub.2 and the product of the overall average Ti concentration and the thickness of the wall of the envelope ranges from 3.7% .mu.m to 42% .mu.m. During the baking step, the tube is shaped to include a bulb-like portion by inflating the silica tube.

摘要： A short arc lamp which has a lamp body in which a concave space is formed, a base plate which is located in a rear part of this body, a transparent part which is located in a front opening of the lamp body, with a frame part in its vicinity, and which hermetically encloses the concave space, and a pair of electrodes forming an arc gap in the concave space. The frame part is connected to a circular conductive ring which is provided with the roughly square cross section and is connected to the lamp body. At least a front side of the circular conductive ring is exposed to the ambient environment. A gap is formed between the frame part and the circular conductive ring. The frame part extends more to the front than the circular conductive ring, and on the exposed surface of the circular conductive ring and on a side of the projecting part of the frame part, step-like projections are formed.
