Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when using a lighting device at a concert venue or the like, the audience causes the lighting device to emit light in a form of light emission corresponding to a mode such as cheering for an idol, for example, causing the lighting device to emit light in an idle image color.

[0005] In addition, when a plurality of idols appear at a concert venue or the like, the audience memorizes, for example, in their heads, a form of light emission corresponding to a mode such as cheering for each of the plurality of idols. Then, the audience selects a form of light emission related to the idol who has appeared or their favorite idol from among various forms of light emission and causes the lighting device to emit light.

[0006] However, as the number of idols increases, the audience must memorize the different lighting patterns corresponding to the specific ways in which they are being supported by each idol. This makes it difficult to quickly select the appropriate lighting pattern for an idol or their favorite idol from among the many available options and activate their light-up device.

[0007] The present invention aims to provide a light-emitting device that can quickly and easily emit light in a form appropriate for each of multiple idols. [Means for solving the problem]

[Figure 2] (a) is a front view of a light-emitting device according to a second embodiment of the present invention, (b) is a view of the information display unit of the light-emitting device according to a second embodiment of the present invention as seen in the Z direction, and (c) is a view of the information display unit of the light-emitting device according to a second embodiment of the present invention in an unfolded state. [Figure 3] This figure shows an enlarged view of the information display section of a light-emitting device according to a second embodiment of the present invention, as well as the information displayed on the information display section. [Figure 4] This is a front view of a light-emitting device according to a third embodiment of the present invention. [Modes for carrying out the invention]

[0017] [First Embodiment] The light-emitting device 1 according to the first embodiment of the present invention is, for example, used by audience members to cheer on idols at concert venues. As shown in Figure 1, the light-emitting device 1 is configured to include a gripping part 3, a light-emitting part 5, an information display part 7, and a control part 9.

[0018] Light-emitting device 1 can be used not only at concert venues but also at sporting event venues, theme parks, and other locations. Specifically, it may be used by spectators to cheer on athletes at sporting event venues, or by cast members and guests at theme parks to enhance the atmosphere and enjoyment.

[0019] Here, for the sake of convenience of explanation, a predetermined one direction in the light-emitting device 1 is defined as the X direction, a predetermined one direction orthogonal to the X direction is defined as the Y direction, and a direction orthogonal to both the X direction and the Y direction is defined as the Z direction.

[0020] The gripping portion 3 is a portion to be gripped by the hand of the spectator, and an operation portion 11 is provided on the gripping portion 3. As the operation portion 11, for example, push button switches 13 (13A, 13B, 13C) are provided.

[0021] The light-emitting portion 5 protrudes from the gripping portion 3 toward the tip side in the Z direction and is integrally provided on the gripping portion 3, and is adapted to emit light (for example, visible light). The information display portion 7 is provided, for example, on the gripping portion 3 and is adapted to display predetermined information 15. Note that the information display portion 7 may be provided on the light-emitting portion 5. Further, the information display portion 7 may be provided on at least any one of the gripping portion 3 and the light-emitting portion 5. Examples of what constitutes the information 15 include characters, figures, symbols, images, etc. or those obtained by appropriately combining these.

[0022] The control portion 9 is configured to include a CPU and a memory. The control portion 9 is adapted to control the light-emitting portion 5 and the information display portion 7. The control portion 9 is adapted to store, in advance in a memory (storage portion), in association with each other, a plurality of types of light-emitting forms in the light-emitting portion 5 and the information 15 displayed on the information display portion 7. Note that, for example, one type of (one set of) information 15 is associated with one type of light-emitting form. In other words, one type of information 15 is adapted to indicate one type of light-emitting form. Also, due to the presence of a plurality of types of light-emitting forms, there are a plurality of sets of information 15.

[0023] Under the control of the control portion 9, when the light-emitting portion 5 emits light in one light-emitting form selected by an operation on the operation portion 11, the information 15 associated with the above one light-emitting form is displayed on the information display portion 7.

[0024] Furthermore, the control unit 9 causes the light-emitting unit 5 to emit light in one of several types of light emission modes selected by the operation of the operation unit 11. Simultaneously with this emission, the control unit 9 displays information 15 associated with the aforementioned one light emission mode (information indicating the aforementioned one light emission mode) on the information display unit 7.

[0025] Here, the light-emitting device 1 will be described in more detail. The gripping part 3 is configured with a gripping part housing 17. The gripping part housing 17 is made of, for example, an opaque synthetic resin that does not transmit light, and is formed in a bottomed cylindrical shape with a bottom wall portion 19 and a cylindrical portion (side wall portion) 21. Because the gripping part housing 17 is formed in a bottomed cylindrical shape, an opening 23 is formed at the end of the gripping part housing 17 opposite to the bottom wall portion 19 (the tip in the Z direction).

[0026] The gripping unit housing 17 contains a power supply unit 27 where a battery 25 is installed, a control unit 9, and a light-emitting element 29, which is composed of, for example, LEDs. The light-emitting element 29 is composed of, for example, red LEDs, green LEDs, and blue LEDs. As a result, the light-emitting element 29 emits light in full color. The light-emitting element 29 and other components are integrated with the gripping unit housing 17.

[0027] The light-emitting element 29 is positioned at the opening 23 of the gripping section housing 17, and the light emitted by the light-emitting element 29 is directed out of the opening 23 towards the outside of the gripping section housing 17 (towards the front end in the Z direction).

[0028] The light-emitting unit 5 is configured with a light-emitting unit housing 31. The light-emitting unit housing 31 is formed in a bottomed cylindrical shape (bottomed cylindrical shape) by comprising a cylindrical portion (side wall portion) 33 and a bottom wall portion 35, and an opening 37 is formed at the end opposite to the bottom wall portion 35 (the base end in the Z direction). For example, the cylindrical portion 33 of the light-emitting unit housing 31 is made of a transparent (including colored transparent) or translucent (including colored translucent) synthetic resin that transmits the light emitted by the light-emitting body 29. The bottom wall portion 35 of the light-emitting unit housing 31 is made of an opaque synthetic resin. The bottom wall portion 35 of the light-emitting unit housing 31 may be made of the same synthetic resin as the cylindrical portion 33 of the light-emitting unit housing 31.

[0029] The light-emitting unit housing 31 is integrally provided with the gripping unit housing 17 so as to close the opening 23 of the gripping unit housing 17, and the gripping unit housing 17 is integrally provided with the light-emitting unit housing 31 so as to close the opening 37 of the light-emitting unit housing 31. As a result, the opening 23 and the opening 37 meet, and a cylindrical closed space is formed between the internal space of the gripping unit housing 17 and the internal space of the light-emitting unit housing 31.

[0030] Furthermore, in the light-emitting device 1, the light emitted by the light-emitting element 29 is directed into the enclosed space, passes through the fleshy part of the light-emitting unit housing 31 (cylindrical part 33), and exits to the outside of the light-emitting unit housing 31. As a result, the light-emitting unit 5 emits light due to the light emitted by the light-emitting element 29.

[0031] The external shape of the light-emitting device 1 is, for example, cylindrical. The height direction of the cylinder is the Z direction, and the radial direction of the cylinder is the X and Y directions. The gripping part 3 is located at the base end in the Z direction, and the light-emitting part 5 is located at the tip end in the Z direction. In addition, an operation switch (not shown) for turning the power of the light-emitting device 1 on and off is provided on, for example, the bottom wall 19 of the gripping part housing 17.

[0032] The information display unit 7 displays information 15 using, for example, an LCD (more specifically, a backlit monochrome liquid crystal display device) 14. Naturally, from the outside of the light-emitting device 1, the audience can see the screen of the LCD 14.

[0033] Furthermore, the LCD 14 of the information display unit 7 may be composed of a full-color liquid crystal display device, and the LCD 14 of the information display unit 7 may be configured to change its light-emitting color according to the light-emitting color of the light-emitting unit 5. For example, the LCD 14 of the information display unit 7 may be configured to emit light in the same light-emitting color as the light-emitting color of the light-emitting unit 5.

[0034] The LCD 14 of the information display unit 7 is formed in a rectangular shape, for example. The LCD 14 is installed on the cylindrical portion 21 of the gripping unit housing 17 such that the longitudinal direction of the rectangle coincides with the circumferential direction of the cylindrical portion 21 of the gripping unit housing 17. In the Z direction, the LCD 14 of the information display unit 7 is installed near the opening 23 of the cylindrical portion 21 of the gripping unit housing 17.

[0035] The LCD 14 may be formed in a shape other than a rectangle (for example, a circle or an ellipse). Furthermore, the LCD 14 may be located in other parts of the gripping housing 17 (for example, in the middle of the cylindrical portion 21 of the gripping housing 17 in the Z direction, the bottom wall portion 19 of the gripping housing 17, or the bottom wall portion 35 of the light-emitting housing 31). In any case, the information display unit 7 is located away from the light-emitting portion (cylindrical portion 33) of the light-emitting unit 5.

[0036] Between the LCD 14 of the information display unit 7 and the light-emitting part of the light-emitting unit 5, there are non-light-emitting parts, such as parts of the gripping unit housing 17. In other words, the LCD 14 of the information display unit 7 is separated from the light-emitting part of the light-emitting unit 5 by a non-light-emitting part (for example, a predetermined part of the gripping unit housing 17).

[0037] In the light-emitting device 1, the light emitted by the LCD 14 does not directly reach the light-emitting section 5. Furthermore, even if the light emitted by the LCD 14 of the information display section 7 is reflected at any point in the light-emitting device 1, this reflected light does not directly reach the light-emitting section 5.

[0038] Furthermore, the brightness of the information 15 displayed on the information display unit 7 is dimmer and less noticeable compared to the brightness of the light emitted from the light-emitting unit 5. Whether the information display unit 7 is off or illuminated and displaying information 15 on the information display unit 7, the brightness of the light emitted from the light-emitting unit 5 is not affected to the naked eye.

[0039] Furthermore, when using the light-emitting device 1 by gripping the gripping part 3 with one's hand, the LCD 14 of the information display unit 7 may be concealed by the fingers or palm of the hand. For example, in a configuration where the LCD 14 is located near the opening 23 of the cylindrical part 21 of the gripping part housing 17, the LCD 14 can be easily concealed with the thumb of the hand gripping the gripping part 3 without requiring a special grip. Also, in a configuration where the LCD 14 is located in the middle of the cylindrical part 21 of the gripping part housing 17 in the Z direction, the LCD 14 can be concealed by the palm of the hand gripping the gripping part 3. A cover (not shown) that can be easily attached to and removed from the gripping part 3 may be provided separately. Furthermore, the LCD 14 of the information display unit 7 may be concealed when the cover is attached to the gripping part housing 17.

[0040] The light emission modes of the light-emitting unit 5 will now be described. The first light emission mode is a mode in which the light is emitted with a constant light color (including white such as incandescent, warm white, neutral white, and daylight) and a constant brightness. The second light emission mode is a mode in which at least one of the light color or brightness changes as time passes. The third light emission mode is a mode in which the light is emitted continuously or turns on and off repeatedly as time passes. The fourth light emission mode is a mode in which the first, second, and third light emission modes described above are combined as appropriate.

[0041] Next, the information 15 displayed on the LCD 14 of the information display unit 7 will be explained with reference to Figures 1(b) to (d). In Figure 1(b), the "red" color, which is an example of the form of light emission from the light-emitting unit 5, the idol's name "Rin", and the name of the group to which the idol belongs, "ABK", are shown as a single set of information (one type of information; a set of information) 15. The information shown in Figure 1(b) and the form of light emission from the light-emitting unit 5 (for example, light emission in red) are associated with each other and are pre-stored in the memory of the control unit 9. Then, the light-emitting unit 5 lights up in red in accordance with the information 15 shown in Figure 1(b) displayed on the LCD 14.

[0042] When the push-button switch 13 of the operation unit 11 is operated as appropriate, the information 15 shown in Figure 1(c) is displayed on the LCD 14 of the information display unit 7. In Figure 1(c), the "yellow" color, which is an example of the form of illumination of the light-emitting unit 5, the name of the idol, "Hina", and the name of the group to which the idol belongs, "ABK", are shown as a single piece of information 15. The information shown in Figure 1(c) and the form of illumination of the light-emitting unit 5 (for example, illumination in yellow) are associated with each other and are stored in the memory of the control unit 9. Then, in response to the information 15 shown in Figure 1(c) being displayed on the LCD 14 of the information display unit 7, the light-emitting unit 5 illuminates in yellow.

[0043] Furthermore, by operating the push-button switch 13 of the operation unit 11 as appropriate, the information 15 shown in Figure 1(d) is displayed on the LCD 14 of the information display unit 7. In Figure 1(d), "sky blue," which is an example of the form of illumination of the light-emitting unit 5, "Mei," which is the name of the idol, and "ABK," which is the name of the group to which the idol belongs, are shown as a single piece of information 15. The information shown in Figure 1(d) and the form of illumination of the light-emitting unit 5 (for example, illumination in sky blue) are associated with each other and are pre-stored in the memory of the control unit 9. Then, in response to the information 15 shown in Figure 1(d) being displayed on the LCD 14 of the information display unit 7, the light-emitting unit 5 illuminates in sky blue.

[0044] Although Figures 1(b) to 1(d) show three types of information 15, the LCD 14 of the information display unit 7 may be configured to switch between and display four or more types of information 15 (for example, from 5 to about 200 types).

[0045] Furthermore, in Figures 1(b) to 1(d), the form of light emission (light emission color) from the light-emitting unit 5, the name of the idol, and the name of the group to which the idol belongs are displayed as a single piece of information 15. Here, the information 15 may be displayed as a single type of information on the LCD 14 of the information display unit 7, with one or two of the light emission form from the light-emitting unit 5, the name of the idol, and the name of the group to which the idol belongs omitted.

[0046] For example, the information 15 shown in Figure 1(b) with the group name removed may be displayed on the LCD 14 of the information display unit 7. Alternatively, the information 15 shown in Figure 1(b) with the emission pattern (red) from the light-emitting unit 5 and the group name removed may be displayed on the LCD 14 of the information display unit 7.

[0047] Next, the operation of the light-emitting device 1 will be explained. First, the power to the light-emitting device 1 is turned on. Then, for example, the light-emitting unit 5 will emit light in its default state and the information display unit 7 will display information in its default state.

[0048] Next, when the operation unit 11 is operated as appropriate, the light-emitting unit 5 emits light in its first emission mode (for example, red), and the information display unit 7 displays the information 15 shown in Figure 1(b). Subsequently, when the operation unit 11 is operated again as appropriate, the light-emitting unit 5 emits light in its second emission mode (for example, yellow), and the information display unit 7 displays the information 15 shown in Figure 1(c). Thereafter, when the operation unit 11 is operated as appropriate, the emission mode of the light-emitting unit 5 and the content of the information 15 displayed in the information display unit 7 are switched.

[0049] The light-emitting device 1 stores multiple types of light emission modes in the light-emitting unit 5 and information 15 related to each of these multiple types of light emission modes, which is displayed on the information display unit 7, in a manner that is associated with each other. Furthermore, in the light-emitting device 1, the light-emitting unit 5 emits light in one of the multiple types of light emission modes selected by the operation unit 11, and the information display unit 7 displays the information 15 associated with the one type of light emission mode selected by the operation unit 11.

[0050] This allows the audience to quickly and easily control the light-emitting device 1 to emit light in a manner appropriate for each of the idols, simply by looking at the information 15 displayed on the information display unit 7, without having to memorize the corresponding light emission patterns for each idol.

[0051] Furthermore, in the light-emitting device 1, the light-emitting unit 5 illuminates in one light-emitting mode selected by operation on the control unit 11, and at the same time, the information 15 associated with the selected light-emitting mode is displayed on the information display unit 7. This allows the audience to check whether the light-emitting mode of the light-emitting unit 5 is correct by looking at the information 15 displayed on the information display unit 7, thus preventing the device from continuing to emit light in an incorrect mode.

[0052] Here, we will describe a modified example of the light-emitting device 1 according to the first embodiment, namely light-emitting device 1a.

[0053] In the modified light-emitting device 1a of the first embodiment, the timing of light emission from the light-emitting unit 5 and the timing of display of information 15 in the information display unit 7 differ from the light-emitting device 1 of the first embodiment, which is not a modified example. Other aspects of the light-emitting device 1a are configured the same as those of the light-emitting device 1 of the first embodiment.

[0054] In the light-emitting device 1a, information 15 is displayed on the information display unit 7 before the light-emitting unit 5 switches the mode of illumination. More specifically, under the control of the control unit 9, the information display unit 7 displays information 15 associated with one mode of illumination selected by the first operation (first operation) on the operation unit 11. At this time, the light-emitting unit 5 does not emit light in the mode of illumination selected by the first operation on the operation unit 11.

[0055] After the information display unit 7 displays the information 15, the light-emitting unit 5 is made to emit light under the control of the control unit 9, in response to a second operation (second operation) on the operation unit 11, which is different from the first operation. The light emitted by the light-emitting unit 5 is in one form of emission selected by the first operation on the operation unit 11. When the second operation is performed, the information displayed on the information display unit 7 is maintained from the information 15 displayed in the first operation.

[0056] Let's explain with an example. Assume that the light-emitting unit 5 is emitting green light and the information display unit 7 is displaying the word "green" (15). In this state, first, while the light-emitting unit 5 is still emitting green light, the first operation displays the word "red" (15) on the information display unit 7. Then, by performing the second operation, while the information display unit 7 is still displaying the word "red" (15), the light-emitting unit 5 will start emitting red light.

[0057] In the light-emitting device 1a, the information display unit 7 displays information 15 associated with one light emission mode selected by a first operation on the operation unit 11. After this display (while this display is being shown), a second operation causes the light-emitting unit 5 to emit light in the selected light emission mode.

[0058] This allows the audience to see the information 15 displayed on the information display unit 7 and know in advance the next mode of illumination from the light-emitting unit 5. This also prevents the light-emitting unit 5 from emitting in the wrong mode (it prevents the illumination in the wrong mode from occurring before it actually happens).

[0059] By the way, in the light-emitting devices 1 and 1a, in addition to the push-button switch 13, a touch panel may also be provided as the operating section 11. That is, a pointing device such as a touch pad may be provided on the LCD 14 of the information display section 7.

[0060] Furthermore, the second operation described above may be performed using a touch panel. That is, the first operation using the push button switch 13 displays predetermined information 15 on the information display unit 7, and then the second operation may be performed by tapping the touch panel.

[0061] Furthermore, the first and second operations described above may be performed using a touch panel. That is, the first operation may be performed by tapping the touch panel, which switches and displays predetermined information 15 on the information display unit 7. After the display of the predetermined information 15 begins, the second operation may be performed by tapping the touch panel again before a predetermined time (for example, 1 to 10 seconds) has elapsed while the predetermined information 15 is still displayed. Note that if the touch panel is tapped again after the predetermined time has elapsed since the display of the predetermined information 15 began, this tap will be considered the first operation. In addition, to prevent malfunctions, the touch panel function may be disabled by operating the push button switch 13 on the operation unit 11 as appropriate, and then the touch panel function may be re-enabled.

[0062] [Second Embodiment] The light-emitting device 1b according to the second embodiment of the present invention, shown in Figures 2 and 3, differs from light-emitting devices 1 and 1a in that the information display unit 7 is configured to simultaneously display multiple types of information 15 relating to multiple types of light emission forms in the light-emitting unit 5. Other aspects of the light-emitting device 1b are configured in the same way as light-emitting devices 1 and 1a. In Figure 2, the display of the light-emitting element 29 is omitted.

[0063] The light-emitting device 1b is provided with multiple LCDs 14 (14A, 14B, 14C, 14D, 14E, 14F, 14G, 14H) of the information display unit 7. Each of the multiple LCDs 14 displays a different type of information (a set of information) 15.

[0064] To further explain, the information display unit 7 is configured to simultaneously display all of the multiple types of information 15 related to the multiple types of light emission forms in the light-emitting unit 5. Alternatively, the information display unit 7 is configured to simultaneously display some of the multiple types of information 15 related to the multiple types of light emission forms in the light-emitting unit 5.

[0065] Furthermore, instead of displaying only one type of information 15 on a single LCD 14, it is also possible to configure the system to display multiple types of information 15 simultaneously on a single LCD 14. For example, it is possible to configure the system to display eight types of information 15 simultaneously on one larger LCD 14. Alternatively, two slightly larger LCDs 14 may be provided. In this configuration, four types of information 15 may be displayed simultaneously on the first LCD 14, and the other four types of information 15 may be displayed simultaneously on the second LCD 14.

[0066] The control unit 9 of the light-emitting device 1b is configured to control the information display unit 7 and the light-emitting unit 5 as follows: Multiple types of information 15 are displayed simultaneously on the information display unit 7. Then, the light-emitting unit 5 emits light in one type of emission form associated with one type of information 15 selected by an operation on the operation unit 11 (third operation).

[0067] Let's explain the light-emitting device 1b in more detail. The light-emitting device 1b shown in Figure 2 is equipped with eight LCDs 14 (14A, 14B, 14C, 14D, 14E, 14F, 14G, 14H). The eight LCDs 14 are arranged in the circumferential direction of the cylindrical portion 21 of the gripping part housing 17 and are mounted on the gripping part housing 17. In the Z direction, the eight LCDs 14 are located near the tip of the gripping part housing 17.

[0068] The information displayed in the information display unit 7 is shown, for example, as shown in Figure 3(a) or Figure 3(b). In the configuration shown in Figure 3(a) or Figure 3(b), one type (one set) of information 15 is displayed on one LCD 14.

[0069] An example will be given to explain how to change the form of illumination at the light-emitting unit 5. Assume that all LCDs 14A to 14H are displaying information 15. By operating the push button switch 13 of the operation unit 11 as appropriate, one of the pieces of information 15 shown on LCDs 14A to 14H (one of the LCDs 14) is selected. The LCD 14 displaying the selected piece of information 15 will, for example, blink to indicate to the audience that it has been selected. With this selection made, the button switch 13 is operated as appropriate to illuminate the light-emitting unit 5.

[0070] The operation unit 11 may be configured as an LCD 14 touch panel. Furthermore, when LCDs 14A to 14H are displaying information 15, the light-emitting unit 5 may be configured to emit light in a form related to the information 15 displayed on LCD 14C when one predetermined LCD 14 (for example, LCD 14C) is tapped.

[0071] In the light-emitting device 1b, the information display unit 7 is configured to display all of the multiple types of information 15 related to the multiple types of light emission forms in the light-emitting unit 5. Alternatively, the information display unit 7 is configured to display only some of the multiple types of information 15 related to the multiple types of light emission forms in the light-emitting unit 5. Details of this will be explained in the fourth operation described later.

[0072] Furthermore, in the light-emitting device 1b, the information display unit 7 displays multiple types of information 15, and the light-emitting unit 5 emits light in a single type of emission form associated with one type of information 15 selected by operation on the operation unit 11 (third operation).

[0073] This allows the audience to quickly select a light emission mode and then have the light-emitting unit 5 illuminate in that selected mode.

[0074] Now, let's explain the case where the number of types of information 15 is greater than the number of LCDs 14 in a light-emitting device 1b where one type (one set) of information 15 is displayed on one LCD 14. As mentioned above, the information display unit 7 of the light-emitting device 1b is configured to simultaneously display multiple types of information 15 related to (indicating the form of) multiple types of light emission in the light-emitting unit 5.

[0075] First, under the control of the control unit 9 of the light-emitting device 1b, the information display unit 7 switches and displays multiple types of information 15 related to multiple types of light emission forms in the light-emitting unit 5 by operation on the operation unit 11 (fourth operation). For example, by appropriately operating the push button switch 13 of the operation unit 11, it is possible to switch from the display shown in Figure 3(a) to the display shown in Figure 3(b), and conversely, to switch from the display shown in Figure 3(b) to the display shown in Figure 3(a).

[0076] Then, under the control of the control unit 9 of the light-emitting device 1b, the light-emitting unit 5 emits light in one type of emission form associated with one type of information selected by an operation on the operation unit 11 (fifth operation) from among the multiple types of information 15 displayed on the information display unit 7.

[0077] In the light-emitting device 1b, the information display unit 7 is configured to display multiple types of information 15 related to multiple types of light emission forms in the light-emitting unit 5. Furthermore, the light-emitting device 1b is configured to switch and display multiple types of information 15 related to multiple types of light emission forms in the light-emitting unit 5 by operation of the operation unit 11 (fourth operation).

[0078] As a result, even if the number of light emission patterns (types of information 15) increases and the information display unit 7 cannot simultaneously display all of the multiple types of information 15, the above switching allows the information display unit 7 to sequentially display all of the multiple types of information 15. The audience can then quickly select a light emission pattern and have the light-emitting unit 5 illuminate in the selected pattern.

[0079] [Third Embodiment] The light-emitting device 1c according to the fourth embodiment of the present invention, shown in Figure 4, differs from the light-emitting device 1b shown in Figures 2 and 3 in that the selection of one piece of information 15 from among multiple types of information 15 displayed on the information display unit 7 is performed using the operation switch 39 that constitutes the operation unit 11. Other aspects of the light-emitting device 1c are configured the same as those of the light-emitting device 1b. Note that the display of the light-emitting element 29 is omitted in Figure 4 as well.

[0080] The operating switch 39 is formed in a ring shape. The operating switch 39 is also provided with a mark 41 that points to one of the multiple LCDs 14 (for example, LCD 14D). The operating switch 39 is mounted on the gripping part 3 (gripping part housing 17) such that its central axis coincides with the central axis of the cylindrical light-emitting device (the central axis extending in the Z direction). In the Z direction, the operating switch 39 is located near the LCD 14.

[0081] Furthermore, the operation switch 39 is designed to be rotated and positioned by the spectator's bare hands relative to the gripping part 3 (gripping part housing 17), with this central axis as the pivot point. The mark 41 is then rotated and positioned to point to one of the multiple LCDs 14 (for example, LCD 14D), and this positioned state can be maintained.

[0082] In Figure 4, the mark 41 shown by the solid line is rotated to the position indicating LCD14D. The mark 41 shown by the dashed line is rotated to the positions indicating LCD14B and LCD14E.

[0083] The light-emitting devices 1, 1a, 1b, and 1c described above are examples of light-emitting devices having a gripping portion, a light-emitting portion provided on the gripping portion that emits light in multiple different forms (multiple types of modes), and an information display portion provided on at least one of the gripping portion or the light-emitting portion that displays information regarding the form of light emission from the light-emitting portion (information indicating the form of light emission from the light-emitting portion). As can be understood, the light-emitting portion emits light in one of multiple forms, which is selected by the user of the light-emitting device via the operating portion.

[0084] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment. [Explanation of Symbols]
