| Appl. No: | 13/809660 |
| Application Filed: | August 16, 2012 |
| مستخلص: | [Object] To provide a light source device which allows the lighting starting properties of a high-pressure discharge lamp to be reliably improved without increasing the entire length of the light source device and exposing an auxiliary lamp to the outside. [Solution] A light source device 10 includes: a high-pressure discharge lamp 12; a bowl-shaped reflector 16 having an insertion hole 44 which is formed in a bottom portion 16a and in which a sealing portion 24 is inserted, an inner space 46, and a reflection surface 48 formed on an inner surface thereof; an auxiliary lamp 14 which emits ultraviolet rays UV; and a base 18 having formed therein an accommodation space 52 in which the auxiliary lamp 14 is accommodated between the base 18 and the outer side of the bottom portion 16a. The object can be achieved by setting a thickness t of the bottom portion 16a to be small such that an outer end portion 24a of the sealing portion 24 inserted in the insertion hole 44 projects into the accommodation space 52 of the base 18 and such that the entirety of an ultraviolet ray emitting space 36 of the auxiliary lamp 14 located along the side surface of the sealing portion 24 faces the sealing portion 24 in the accommodation space 52. |

| Claim: | 1. A light-emitting device, comprising: a high-pressure discharge lamp having a light-emitting portion having therein a pair of main electrodes opposed to each other and elongated sealing portions extending outward from the light-emitting portion; a bowl-shaped reflector having an insertion hole which is formed in a bottom portion and in which one of the sealing portions and a current-carrying wire for an auxiliary lamp are inserted, an inner space in which the high-pressure discharge lamp is accommodated with the one sealing portion inserted in the insertion hole and a reflection surface which is formed on an inner surface of the reflector and which reflects light from the high-pressure discharge lamp; an auxiliary lamp having an elongated ultraviolet ray emitting space in which ultraviolet rays are generated; the current-carrying wire which is connected to an external lead rod protruding from the other sealing portion opposite to the sealing portion inserted in the insertion hole, and which is wound around an outer surface of a discharge container of the auxiliary lamp to form an external electrode; and a base attached over an outer surface of the bottom portion of the reflector and having formed therein an accommodation space in which the auxiliary lamp is accommodated between the bottom portion and the base, wherein: a thickness of the bottom portion of the reflector in which the insertion hole is formed is set such that an outer end portion of the sealing portion inserted in the insertion hole projects through the insertion hole into the accommodation space of the base, and such that the entire elongated ultraviolet ray emitting space of the auxiliary lamp is located along an elongated side surface of the sealing portion, faces the sealing portion, and is accommodated in the accommodation space; the base is a bowl-shaped member including a main body portion in which the accommodation space is formed and which is attached to a surface of the bottom portion of the reflector, and a cover portion which extends from the main body portion so as to cover the bottom portion of the reflector with a second gap from an outer surface of the reflector and whose front end portion is attached to the outer surface; and when the base is attached to the bottom portion of the reflector, a center of the light-emitting portion of the high-pressure discharge lamp accommodated in the reflector is positioned on an opening face, of the base, which is defined by a periphery of the second gap on the front end portion side, or is positioned inwardly from the opening face. |
| Claim: | 2. A light-emitting device, comprising: a high-pressure discharge lamp having a light-emitting portion having therein a pair of main electrodes opposed to each other and elongated sealing portions extending outward from the light-emitting portion; a bowl shaped reflector having an insertion hole which is formed in a bottom portion and in which one of the sealing portions and a current-carrying wire for an auxiliary lamp are inserted, an inner space in which the high-pressure discharge lamp is accommodated with the one sealing portion inserted in the insertion hole and a reflection surface which is formed on an inner surface of the reflector and which reflects light from the high-pressure discharge lamp; an auxiliary lamp having an elongated ultraviolet ray emitting space in which ultraviolet rays are generated; the current-carrying wire which is connected to an external lead rod protruding from the other sealing portion opposite to the sealing portion inserted in the insertion hole, and which is wound from an outer surface of a discharge container of the auxiliary lamp to form an external electrode; and a base attached over an outer surface of the bottom portion of the reflector and having formed therein an accommodation space in which the auxiliary lamp is accommodated between the bottom portion and the base, wherein: a thickness of the bottom portion of the reflector in which the insertion hole is formed in set such that an outer end portion of the sealing portion inserted in the insertion hole projects through the insertion hole into the accommodation space of the base, and such that the entire elongated ultraviolet ray emitting space of the auxiliary lamp is located along an elongated side surface of the sealing portion, faces the sealing portion, and is accommodated in the accommodation space; there is a first gap between an inner surface of the insertion hole of the reflector and an outer surface of the sealing portion inserted in the insertion hole; the base is a bowl-shaped member including a main body portion in which the accommodation space is formed and which is attached to a surface of the bottom portion of the reflector, and a cover portion which extends from the main body portion so as to cover the bottom portion of the reflector with a second gap from an outer surface of the reflector and whose front end portion is attached to the outer surface; and when the base is attached to the bottom portion of the reflector, a center of the light-emitting portion of the high pressure discharge lamp accommodated in the reflector is positioned on an opening face, of the base, which is defined by a periphery of the second gap on the front end portion side, or is positioned inwardly from the opening face. |
