Description of the Invention: TECHNICAL FIELD The present invention relates to a reflector lamp with a mirror used in a projection machine such as a projector. [Prior Art] For example, as a light source device of a projector, a combination of a short arc discharge lamp and a concave mirror is used. Since the projector is required to have a light source with good color rendering, as a short arc discharge lamp, instead of a metal halide lamp, an ultrahigh pressure mercury lamp having a very high mercury vapor pressure has recently been used. The purpose is to increase the mercury vapor pressure to suppress the diffusion of short arcs and to improve color rendering and light output.

The F wire 17 is led out from the F seal portion 28. The R electrode 13 is connected to one end of the R molybdenum foil 16, and the R wire 18 is connected to the other end of the R molybdenum foil 16. The R wire is led out from the R seal portion 29 to the outside. The bridge mirror 3 is in the shape of a part of the circular shape of the rotating bridge. The rounded mirror 3 is made of quartz glass. The arc tube 1 is disposed such that the F electrode 12 becomes the opening portion 3a side of the elliptical mirror 3 and the R electrode 1 3 becomes the neck portion 3b side of the elliptical mirror 3. The central axis of the arc tube 1 is aligned with the central axis obtained by connecting the opening 3a of the elliptical mirror 3 and the neck 3b of the 201042702. The center displacement of the light-emitting portion 11 is shifted toward the neck 3b side from the focus of the elliptical mirror 3. A structure in which the arc tube 1 is attached to the elliptical mirror 3 is formed. The material of the ceramic ring 2 is talc-based ceramic. The talc-based ceramics are obtained by firing and finishing high-purity mica (talc) as a main raw material at a high temperature. Talc is also excellent in forming, dimensional accuracy, and high-temperature insulation or heat resistance. The ceramic ring 2 is provided with a fitting portion 22 in which the neck portion 3b that is fitted to the elliptical mirror is fitted at the end portion 'fixed to the side of the elliptical mirror 3. Further, the ceramic ring 2 is provided with an abutting portion 21 which abuts against the axial end portion of the neck portion 3b of the elliptical mirror 3 at the end portion 'fixed to the side of the elliptical mirror 3. The abutting portion 21 is formed at a right angle with respect to the center line direction of the arc tube 1. Further, the ceramic ring 2 is provided with a cutout portion 23 that cuts the fitting portion 22 at an end portion 'fixed to the side of the elliptical mirror 3 (see Fig. 1). The cutout portion 23 acts as a vent. In the discharge lamp 100 with a mirror attached, the cutout portion 23 is opened in a state where the ceramic ring 2 is fixed to the elliptical mirror 3. When the arc tube 1 is broken for some reason, since the glass fragments fly out from the cutout portion 23, the mesh body 7 is provided in the cutout portion 23 as shown in Fig. 1. . The ceramic ring 2 is fixed to the elliptical mirror 3 by the bonding agent 4a. The main component of the bonding agent 4a is silica. The arc tube 1 is provided with a space portion 25 different from the light-emitting portion 11 in the vicinity of the F-sealing portion 28 of the F-molybdenum foil 15. This space portion 25 is a hole in which the F-molybdenum foil 15 passes through the center thereof and contains the size of the mercury 14 and the rare gas. The space portion 25 is also referred to as an ultraviolet enhancer (uv_Enhancer) and a light bulb 201042702 (Bubble). The space portion 25 and the trigger line 9 are provided to lower the starting voltage of the light-emitting portion 11 of the arc tube 1. The phenomenon that the space portion 25 and the trigger line 9 are provided to reduce the starting voltage of the light-emitting portion 11 of the arc tube 1 is discussed (see Fig. 3). The trigger line 9 is connected to the R wire 18. Therefore, the trigger wire 9 and the F molybdenum foil 15 are different electrodes. An electric field is formed between the trigger wire 9 and the F molybdenum foil 15 and an initial start occurs in the space portion 25. At this time, electrons are generated in the space portion 25 by the tip end portion of the F molybdenum foil 15 at a relatively low voltage, and discharge occurs. The capacitor discharge between the F molybdenum foil 15 and the trigger wire 9 generates UV (ultraviolet rays), and the UV reaches the light-emitting portion 沿着 along the quartz bulb 1 a between the space portion 25 and the light-emitting portion 1 1 . In the light-emitting portion 11, the uv photons are generated by photoelectrons to generate electrons, causing a single discharge of the light-emitting portion 11. After this discharge, only a few hundred volts is required for glow discharge. After forming an arc in less than one second, it is less than 100 volts. Even if it is stored in complete darkness for several days, the luminous tube 1 is stably illuminated at a voltage which is considerably lower than 5 kV.如此 In this way, the UV radiation activated by the lamp is activated in accordance with the space portion, and the UV is guided to the light-emitting portion by the light guiding effect of the quartz glass, and a free charge carrier is generated in the light-emitting portion 11. Due to the free charge carrier, it is possible to start the arc tube 1 with a lower voltage (2.5 to 5 kV). Here, the manufacturing method of the arc tube 1 will be briefly described. (1) Using a quartz glass tube, a hollow quartz bulb 1a having a space portion which becomes a substantially spherical light-emitting portion 11 at the center portion is manufactured; (2) an R electrode system 27 is inserted into the quartz bulb la; (3) Temporarily sealed quartz Light bulb ia's R electrode system 27 side end; -10- 201042702 (4) Perform vacuum pumping in the quartz bulb la; (5) Introduce rare gas (argon) into the quartz bulb la; (6) Temporarily seal the quartz bulb The end portion of the F electrode system 26 of la: (7) The quartz bulb la in the vicinity of the R molybdenum foil 16 is heated and melted to be sealed; (8) the temporary sealing of the end portion of the F electrode system 26 of the open quartz bulb la; Put the F electrode system 26 and the mercury 14 into the quartz bulb la; 〇 (10) connect the quartz bulb U to the device and evacuate it; (11) introduce a rare gas (argon); (12) temporarily seal the quartz The end portion of the F electrode system 26 of the bulb la; (13) The quartz bulb 1a in the vicinity of the F molybdenum foil 15 is heated and melted by another means to seal; (14) In the middle of sealing the F molybdenum foil 15, the quartz is made The heating of the bulb la is spread to a predetermined distance; (15) the unheated portion of the quartz bulb la is formed into a space 25; Q (16) detached from the other quartz lamp apparatus ia, i.e. the arc tube 1 is completed. Since the space portion 25 is formed by the above-described procedure, the rare gas and the mercury are present inside. Fig. 4 is a view showing the first embodiment, and is a plan view of the arc tube 1. The first embodiment has a feature in the configuration of the arc tube 1.
