Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a so-called penlight or cheerlight, which is mainly used to enhance the atmosphere at an indoor concert or various events at dusk.

[0002]

[Prior art]

 Conventionally, as described in Japanese Patent Application Laid-Open No. 9-282902, this type of light emitting device is composed of a light emitting tube to which a light emitting element is fixed, and a grip portion for accommodating a battery. The power supply to the light emitting element is performed by forcibly screwing the grip portion to the light emitting tube, while the power is cut off by loosening the screw of the grip portion to the light emitting tube.

[0003]

[Problems to be solved by the invention]

 Therefore, when the power is turned off, that is, when not in use, the light emitting tube and the grip are not firmly fixed, and when the light emitting device is transported in this state, the vibration causes the two screws to be disengaged and separated, and the battery is also replaced. It was causing scattering. Further, when it is desired to change the light emission color, the entire light emitting tube including the light emitting element has to be replaced, and there have been various problems in terms of price and usability.

An object of the present invention is to provide a rod-shaped light-emitting device in which power is not supplied to a light-emitting element, that is, when the light-emitting device is not used, each screw portion is securely fastened, and each tube does not fall apart during transportation or the like. I do. Another object of the present invention is to provide a rod-shaped light emitting device that can easily change the color of emitted light.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the rod-shaped light emitting device of the present invention is provided with a moving piece at a mounting portion of the light emitting element. The movable piece is provided with a conductive terminal at a position between one electrode terminal of the light emitting element and one end of the battery. When the front cylinder is firmly screwed into the rear cylinder, the moving piece is pushed by the front cylinder against the resilience of the spring pressing the battery, and the conductive terminal is separated from the electrode terminal of the light emitting element. Conversely, when the screwing of the front cylinder is loosened, the moving piece is pushed toward the light emitting element by the elastic force of the spring, and the conductive terminal contacts the electrode terminal of the light emitting element. The light-emitting tube and the front tube are fixed by screwing, and translucent light-emitting tubes of different colors are prepared, and various light-emitting colors are obtained by replacing these.

[0006]

[Embodiment of the invention]

 In the light emitting device configured as described above, when power is not supplied to the light emitting element, that is, when not in use, the two cylinders at the front and rear stages are securely tightened, and there is a concern that the screw between the two tubes may be loosened due to vibration during transportation. Absent.

[0007] The emission color is changed by exchanging the emission tube screwed into the front tube with a desired color.

[0008]

【Example】

 FIG. 1 is a front view of a rod-shaped light emitting device according to the present invention, which is composed of a front tube 1, a rear tube 2 and a bottom cover 3 serving as a grip portion, and a hollow translucent light emitting tube 4. Note that a cap 5 for closing the hollow portion is fitted to the tip of the light emitting tube 4.

FIG. 2 is an enlarged longitudinal sectional view of a main part of the present invention. Male and female screws 6 are provided in the front cylinder 1 and the rear cylinder 2, and male and female screws 7 are provided in the rear cylinder 2 and the bottom cover 3. The male and female screws 8 are provided on the light emitting tube 4 so as to screw together. A pedestal 10 of the light emitting element 9 is fitted to the left end of the rear tube 2. A movable piece 11 is mounted on the pedestal 10 so as to be movable left and right, and a conductive terminal 12 is fixed to the right end thereof.

The one electrode terminal 13 of the pedestal 10 is bent upward and is sandwiched between the pedestal 10 and the rear cylinder 2 together with the stopper 15 and the spring 16. The other electrode terminal 14 of the pedestal 10 is located substantially at the center. A light reflector 27 is fixed in the front tube 1.

A spring pedestal 17 is fitted to the bottom cover 3, and a conductor 18 is protruded from the inside of the pedestal 17 to the upper outside, and a protruding piece of a washer 19 contacts the conductor 18. The right end of the spring 16 is in contact with the washer 19. Another spring 20 having a higher resilient force than the spring 16 is fitted in the spring base 17. A hole 21 for passing a string or the like is formed in an outer corner portion of the bottom cover 3, and rubber rings 22, 23, and 24 for waterproofing are provided in fitting portions of the respective cylinders. When the battery 25 is a button type, the outside is not insulated. Therefore, when a plurality of batteries are used, an insulating sheet (not shown) is preferably interposed between the battery 25 and the spring 16 or the spring 16 is preferably insulated.

FIG. 3A is a left side view of the pedestal 10, FIG. 3B is a front view of the pedestal 10, and FIG. 3C is a front view of the movable piece 11, and the movable piece 11 is a hollow portion 26 of the pedestal 10. , 26 can be moved to the left and right, and is constantly pushed to the left by the battery 25 pushed by the spring 20, the left end of which contacts the right end of the light reflector 27.

Accordingly, as shown in FIG. 2, in a state in which the front cylinder 1 is securely screwed to the rear cylinder 2, the light reflector 27 pushes the movable piece 11 rightward with respect to the pedestal 10, and the conductive terminal 12 is electrically connected. The power supply circuit to the light emitting element 9 is turned off by separating from the tip 14. On the other hand, if the screw between the front cylinder 1 and the rear cylinder 2 is loosened, the moving piece 11 is pushed to the left by the battery 25, and the conductive terminal 12 contacts the electrode terminal 14 to turn on the power supply circuit. The electrode terminal 13 is always electrically connected to the other end of the battery 25 through the path of the spring 16, the washer 19, the conductor 18, and the spring 20.

[0014]

[Effect of the invention]

 As described above, since the power supply to the light-emitting element is cut off when the front and rear cylinders are screwed tightly as described above, the rod-shaped light-emitting device of the present invention can be transported in this state and subjected to vibration. It is possible to prevent the two cylinders from falling apart without loosening the screw of the cylinders.

Further, since the light emitting tube is screwed to the front tube, it can be easily replaced. To obtain a desired light emitting color, only the light emitting tube of that color needs to be prepared, and the light emitting tube can be provided at low cost.
