A light source device including a light emitting member 5 is mounted on the inner cylinder 4 and is assembled by inserting the inner cylinder 4 in the axial direction A toward the inner side of the outer cylinder 3 at the time of assembly.

  As a feature of the shape of the inner cylindrical body 4, a first range-expanding portion 4 a that gradually increases in diameter from the front end is formed in a predetermined range at the front portion in the insertion direction, and a rear portion at the rear portion in the insertion direction. There is a point that a predetermined range is formed in the second enlarged portion 4b that is gradually enlarged by being hung, and the amount of enlargement of the second enlarged portion 4b is in particular the rear end portion 15b of the outer cylindrical body 3 and the second enlarged portion. It is provided to such an extent that it comes into contact with the diameter portion 4b. With these characteristics, at the time of assembly, as the inner cylinder 4 is inserted into the outer cylinder 3, the first enlarged-diameter portion 4a aligns both cylinders and then the rear end of the outer cylinder 3 15b and the 2nd enlarged diameter part 4b are contact | abutted, and it acts so that insertion of the inner side cylinder 4 may be controlled.

  In the present embodiment, both end portions of the outer cylinder 5 have openings 15a and 15b. This makes it possible to insert the inner cylindrical body 4 from either direction, thereby producing an effect that contributes to ease of assembly and cost reduction.

  The light source device includes a light emitting member 5, a light emission control device configured on the circuit boards 6 and 7, a battery 8, and an operation member 12. The light quantity of the light emitting member is controlled by a light emission control device. The light emission control device has a sound collector 10 and a power amplifier circuit 11, amplifies the sound input to the sound collector 10 by the power amplifier circuit 11, and outputs the output current to the light emitting member. Control to increase or decrease the amount of light.

  The light emission control device is housed in the inner cylinder 4 by dividing the component parts into two circuit boards. The first circuit board 6 mounts the light emitting member 5 and the light emission control device 11 and is disposed at the front part in the insertion direction of the inner cylindrical body 4. The second circuit board 7 carries the operation member 12 and is arranged at the rear part in the insertion direction of the inner cylinder. The battery 8 is disposed so as to be sandwiched between the first circuit board 6 and the second circuit board 7, and the first circuit board 6 and the second circuit board 7 are electrically connected by lead wires 9a and 9b. The By arranging a plurality of parts in the axial direction, the light source device can be compactly laid out so that it can be accommodated in the inner cylinder 4.

  FIG. 3 is a sectional view taken along line III-III in FIG. The inner cylinder 4 forms at least a part of the opening 14 communicating with the inside and outside of the cylinder in the range of the position where the battery 8 is accommodated. After the battery 8 is inserted from the opening 14, the inner cylinder 4 is formed. Since the opening 14 is covered with the outer cylinder 3 by being inserted into the outer cylinder 3, the outer cylinder 3 also serves as a lid for the opening 14.

  In the present embodiment, the light emitting member 5 uses a light emitting diode, and the light amount is increased or decreased by the power amplifier circuit 11. However, the light emitting member 5 may be an incandescent light bulb without being limited to the present embodiment. The increase / decrease may be performed by duty control using a microcomputer.

  FIG. 4 is a cross-sectional view of the material layer 3a and the reflective layer 3b of the outer cylindrical body 3, and a schematic cross-sectional view showing a state of light distribution of the light Ra and Rb irradiated from the light emitting member 5. In the outer cylindrical body 3, a reflective layer 3b is formed by coating a reflective material containing metal on the surface of a material layer 3a having transparency. The reflection layer 3b is configured to reflect part of incident light and transmit part of the light, and has an effect similar to a so-called beam splitter or magic mirror. With this configuration, the outer cylindrical body 3 transmits a part of the incident light from the light emitting member 5, while the reflected part of the light is guided inside the material layer 3 a like an optical fiber so as to be the outer cylindrical body 3. Since light can be emitted from both end faces, a fantastic visual effect can be produced by the fact that the vicinity of the light emitting member 5 and both ends of the outer cylindrical body 3 shine. In addition, the reflective layer 3b reflects the light from the outside and acts in the same way as a mirror, so that the components housed in the outer cylinder 3 can be concealed. Appearance can be improved.

  Here, Ra indicates a state in which a part of the light incident from the light emitting member 5 is transmitted through the reflection layer 3b of the outer cylindrical body 3 and transmitted to the outside. Rb shows a state in which a part of the light incident from the light emitting member 5 is reflected by the reflection layer 3b and guided inside the material layer 3a like an optical fiber. Rc indicates that the light incident from the outside is reflected by the reflective layer 3b and has the same effect as a mirror.

  The reflective material coating method may be vapor deposition in which a metal, an oxide, or the like is evaporated to adhere to the surface of the material, or a film-like reflective material may be wound.

  FIG. 5 is an explanatory diagram of the usage pattern of the present invention.
