And this socket 7 When the non-flash lamp 2 (described later) is detachably attached, the xenon flash The shuffle 2 is in a state of being exposed from the upper opening of the tubular body 1. Furthermore, the cylinder A rectifier circuit 8 composed of a plurality of diodes (not shown) is provided inside the main body 1. The rectifier circuit 8 is electrically connected to the power supply cable 6 and the socket 7, In addition, the xenon flash lamp 2 is configured so that the direction of current flow is the forward direction. Has been done. A cylindrical body 1 and a cylindrical lid 3 (described later) are provided on the outer peripheral portion of the upper opening. A female screw portion 1b for screwing together with.

[0011]   The xenon flash lamp 2 has high-purity xenon gas sealed inside. The xenon flash lamp has an anode (not shown) and a cathode (not shown). ), A high voltage is applied to generate arc light emission, and It emits more light.

[0012]   The tubular lid 3 is made of aluminum and has a tubular shape. A cylindrical portion 3a that covers the side surface of the cylinder, and a xenon flash flash provided inside the cylindrical portion 3a. A condenser lens 4 (described later) for condensing the light from the pump 2 and a cylindrical lens 3a. Noise generated from the xenon flash lamp 2 is blocked and leaks to the outside. And a sound-transmitting light-transmitting plate 5 (described later) for preventing the noise.

[0013]   The condenser lens 4 is composed of a convex lens and emits light from the xenon flash lamp 2. It has a function of condensing the light that is generated.

[0014]   The sound-transmitting transparent plate 5 is made of tempered glass and is provided in close contact with the inner surface of the tubular portion 3a. To be The sound-transmitting transparent plate 5 is used for the light emitted from the xenon flash lamp 2. The noise emitted from the xenon flash lamp 2 It has the function of insulating sound so that it does not leak outside. In addition, the sound-transmitting transparent plate 5 has a strong Quartz glass, BK7, or the like may be used instead of the fog glass.

[0015]   Here, a method of forming the tubular lid 3 will be described in detail. The tubular lid 3 is made of aluminum. It is configured by a first tubular body 31 and a second tubular body 32 that are tubularly configured by a frame. first Both ends of the cylindrical body 31 are opened, and the condensing lens 4 is formed on one opening end with an adhesive or the like. Is stuck. Further, both end surfaces of the second tubular body 32 are open, and one open end is near A locking piece 3b is provided on the inner surface of the, and the female screw portion 1b is formed on the inner surface near the other opening end. A male screw portion 3c to be screwed is provided.

[0016]   First, the sound insulating translucent plate 5 having an outer diameter slightly smaller than the inner diameter of the second tubular body 32 is attached. The ring-shaped packing 9 is used to engage the locking piece 3b from the opening end near the locking piece 3b. Stop it. Also, the opening end of the first cylindrical body 31 on the side where the condenser lens 4 is fixed is It has an outer diameter slightly smaller than the inner diameter of the second cylindrical body 32. And the first cylindrical body 3 The opening end on the side where the condenser lens 4 of 1 is fixed to the locking piece 3b of the second cylindrical body 32. Insert it from the open end on the near side and place it on the sound-transmitting transparent plate 5 via the packing 9. It At this time, the sound-transmitting transparent plate 5 is packed by the first cylinder body 31 and the second cylinder body 32. It is sandwiched through the guide 9. The first cylinder 31 and the second cylinder 32 are integrally fixed with the screw 10. Then, the tubular lid body 3 is formed.

[0017]   The tubular lid 3 formed as described above has a female screw portion 1b and a male screw portion 3c. By being screwed, it is detachably attached to the tubular body 1. The cylindrical lid 3 is a cylindrical book. When mounted on the body 1, the side surface of the xenon flash lamp 2 and the second cylindrical body 32, that is, about 2 mm away from the inner surface of the cylindrical portion 3a, and the xenon flash The upper light projecting portion 2a of the lamp 2 is placed in close proximity to the sound insulating transparent plate 5. Therefore, When the xenon flash lamp 2 has to be replaced due to its life etc., the cylindrical lid The body 3 can be easily removed from the tubular body 1, and the upper surface of the socket 7 is above the tubular body 1. The xenon flash lamp 2 can be easily attached and detached because it is located on the same plane as the surface opening. Easy to do.

[0018]   In the lamp device L configured as described above, power is supplied from the main power supply unit (not shown). The power supply cable 6, the rectifier circuit 8, and the socket 7 are used to connect the xenon flash flasher. Power is supplied to the lamp 2, and a high voltage is applied between the anode and the cathode of the xenon flash lamp 2. A voltage is applied and the xenon flash lamp 2 repeatedly emits light in a short time. Then, light is emitted from the upper light projecting portion 2a of the xenon flash lamp 2, and The light passes through the sound-transmitting transparent plate 5 and then is condensed by the condenser lens 4 to open the upper surface of the cylindrical lid 3. Radiated from the mouth to the outside. In addition, an optical fiber (Fig. (Not shown), the light condensed by the condenser lens 4 enters the optical fiber. It is incident on the end face.

[0019]   At this time, if the xenon flash lamp 2 emits light, the xenon flash run The cup 2 vibrates inside the tubular portion 3a, and this vibration causes noise. But Kise A sound-transmitting translucent light provided in close proximity to the upper light projecting portion 2a of the non-flash lamp 2. The plate 5 keeps the xenon flash lamp 2 sealed in the tubular portion 3a. Therefore, it is necessary to reduce the amount of this noise leaking to the outside from the upper opening of the cylindrical lid 3. You can In addition, the distance between the side surface of the xenon flash lamp 2 and the inner surface of the cylindrical portion 3a. Since they are separated by about 2 mm, they are cylindrical even if the xenon flash lamp 2 vibrates. There is no contact with the inner surface of the portion 3a, and noise caused by the contact can be prevented. .

[0020]   In addition, in the lamp device L having the above-mentioned configuration, four lamps are used at an emission frequency of 30 Hz. The noise value when the device L is made to emit light at the same time is about 58 dB. The noise level is reduced by about 27 dB.

[0021]   The above embodiments are merely examples of the present invention, and may be appropriately changed within the scope of the present invention. Obviously, variations and modifications are included in the scope of the claims of the present application. . For example, in this embodiment, the tubular body and the tubular lid are screwed together, but both can be screwed together. They may be fixed together.

[0022]

[Effect of device]

  In the device of the present invention, the xenon flash lamp vibrates during light emission. It is possible to reduce the amount of noise generated from the lamp device. Also, If the Senon flash lamp reaches the end of its life, remove the tubular lid from the tubular body. Once removed, the xenon flash lamp can be easily replaced.
