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:
In a light source device, in each division of an image frame, two or more of the color lights X, Y and Z (e.g., red, green and blue) can be projected simultaneously. Each of the color lights X, Y and Z is divided into two in terms of time so that synthesized light of one group of division color lights enters a first spatial modulation element. Synthesized light of another group of division color lights enters a second spatial modulation element, whereby gradation of each color light in each of the first and second spatial modulation elements is controlled.

A discharge lamp lighting apparatus for lighting a discharge lamp, comprises an inverter which reverses a polarity of an output voltage and applies alternating voltage to the discharge lamp, and an inverter control circuit which generates an inverter control signal defining a polarity reversal operation of the inverter, based on a polarity reversal timing signal, wherein when the number of polarity reversals in one cycle of the polarity reversal timing signal is even, the inverter control circuit intermittently performs a first operation in which successive pulse-like part of the polarity reversal operation based on the polarity reversal timing signal is disregarded by odd number of times.
