[0011] The light-emitting device 1 (capable of emitting light in a wide range of light-emitting modes) according to an embodiment of the present invention is used by spectators at a concert venue, for example, to hold in their hands in order to cheer on their favorite idol, and as shown in FIG. 1, it is configured to include a housing 3, a light emitter 5, an operation unit 7, and a control unit 9. Note that the light-emitting device 1 may also be used at sporting event venues, theme parks, and the like, in addition to concerts. That is, the light-emitting device 1 may be used by spectators at sporting event venues to cheer on athletes, or by cast members and guests at theme parks to enhance the atmosphere and enjoy the event.

[0012] The housing 3 is made of, for example, synthetic resin, and is configured to include a base end portion (gripping portion) 11 and a tip end portion (light emitting portion) 13. The base end portion 11 is made of an opaque synthetic resin that does not transmit light. The tip end portion 13 is made of a transparent or semi-transparent (including colored transparent and colored semi-transparent) synthetic resin that transmits light (for example, visible light). A space is formed inside the housing 3.

[0013] The light emitter 5 is provided inside the housing 3. As shown in Fig. 2, the light emitter 5 is configured to include a red LED 15 that emits red light, a green LED 17 that emits green light, and a blue LED 19 that emits blue light.

[0014] 2, the light emitter 5 is configured to include a first white LED 21 and a second white LED 23 having a lower color temperature than the first white LED. The operation unit 7 is provided in the grip portion 11 of the housing 3. The control unit 9 is configured to include a CPU and a memory. The control unit 9 is provided inside the grip portion 11 of the housing 3.

[0015] A battery installation section 25 is provided within the grip section 11, in which a battery 27 is installed as a power source for the light-emitting device 1. The control section 9 receives power from the battery 27 installed in the battery installation section 25, and changes the brightness of each of the LEDs 15, 17, 19, 21, and 23 appropriately in response to operations on the operation section 7, causing the light-emitting body 5 to emit light in various modes.

[0016] An LED that emits daylight, daylight white, or white light is used as the first white LED 21. The color temperature of daylight light is 5700K or more and 7100K or less. The color temperature of daylight white is 4600K or more and less than 5700K. The color temperature of white is 3800K or more and less than 4600K.

[0017] An LED that emits warm white or incandescent light is used as the second white LED 23. The color temperature of warm white is 3250K or more and less than 3800K. The color temperature of incandescent light is 2600K or more and less than 3250K.

[0018] The light emitting device 1 will now be described in more detail.

[0019] The base end portion 11 is formed in a tubular shape with a bottom (for example, a cylindrical shape with a bottom), and the tip end portion 13 is also formed in a tubular shape with a bottom (for example, a cylindrical shape with a bottom). The tip end portion 13 is integrally installed on the base end portion 11 so that the opening of the base end portion 11 and the opening of the tip end portion 13 mate with each other.

[0020] The light emitting body 5 is provided near the opening of the base end portion 11, and light emitted by the light emitting body 5 passes through the tip end portion 13 and is radiated to the outside of the tip end portion 13. In other words, when the light emitting body 5 emits light, the tip end portion 13 of the light emitting device 1 glows when viewed from outside the light emitting device 1.

[0021] The operation unit 7 is configured to include a power switch (for example, a slide switch) 29 for turning on and off the power of the light emitting device 1, and a push button switch 31 for changing the light emission mode of the light emitting body 5.

[0022] With the power of the light-emitting device 1 on, pressing the push button switch 31 as needed changes the brightness of the red LED 15, green LED 17, blue LED 19, first white LED 21, and second white LED 23. For example, the color emitted by the light-emitting body 5 changes in the following order: red → yellow → green → light blue → blue → pink → white → red → . . .

[0023] In the light emitting device 1, the light emitter 5 is configured to include a red LED 15, a green LED 17, a blue LED 19, a first white LED 21, and a second white LED 23 having a lower color temperature than the first white LED. This allows the light emitter 5 to emit light in a wider range of light emission modes (more colorful colors) than conventional light emitting devices.

[0024] That is, by emitting light from the first white LED 21 in addition to the red LED 15, green LED 17, and blue LED 19, the light-emitting device 1 can be made to emit light in pastel colors, and by emitting light from the second white LED 23, the light-emitting device 1 can be made to emit light in a warm, subdued color with a subdued brightness.

[0025] This allows the light emitting device 1 to emit light in a color that more closely matches the image color of the idol when the audience cheers for their favorite idol at a concert venue, further enhancing the atmosphere of the concert venue. Also, when using the light emitting device 1 to cheer on athletes at a sporting event venue or in a theme park, the light emitting device 1 can emit light in a color that suits the situation.

[0026] Furthermore, the light emitting device 1 can be said to be equipped with the first white LED and the second white LED 23 so that the emitted light color during use is warm and subdued in brightness. The light emitting device 1 emits light in a subdued color that is warm and subdued in brightness. This prevents the light emitting device 1 from being too conspicuous and obscuring idols, athletes, theme park performances, etc. when used at concert venues, sporting event venues, or theme parks.

[0027] In addition, in the light emitting device 1, the first white LED 21 is an LED that emits daylight color, neutral white color, or white color, and the second white LED 23 is an LED that emits warm white color or incandescent color, thereby making it possible to more reliably achieve the above-mentioned light emission in a variety of colors.

[0028] In the light-emitting device 1, the control unit 9 keeps the brightness of the red LED 15, the green LED 17, and the blue LED 19 at a constant value (a state in which the brightness is fixed at a predetermined value). The control unit 9 may be configured to gradually change the brightness of at least one of the first white LED 21 and the second white LED 23 in a stepwise or continuous manner over time.

[0029] Furthermore, control unit 9 maintains the brightness of red LED 15, green LED 17, and blue LED 19 at a constant value. Then, in response to an operation on operation unit 9, the brightness of at least one of first white LED 21 and second white LED 23 may be gradually changed in a stepwise or continuous manner.

[0030] While the brightness of red LED 15, green LED 17, and blue LED 19 is kept constant, the brightness of at least one of first white LED 21 and second white LED 23 is changed. This makes it possible to change the saturation while maintaining the hue of the light emitted by light-emitting body 5, further enhancing the atmosphere of the concert hall.

[0031] 3, the light emitter 5 may further include a yellow LED 33. The control unit 9 maintains the brightness of the red LED 15, green LED 17, and blue LED 19 at a constant value. In this state, the control unit 9 may gradually change the brightness of at least one of the first white LED 21, second white LED 23, and yellow LED 33 in a stepwise or continuous manner. The addition of the yellow LED 33 allows the light emitter 5 to emit light in an even wider variety of colors.

[0032] 4, the first white LED 21 is configured to include, for example, a blue LED 19 and a phosphor 35 that absorbs the blue light emitted by the blue LED 19 and emits yellow, which is a complementary color of blue. The blue light emitted by the blue LED 19 and the yellow light emitted by the phosphor 35 are combined to emit white, neutral white, or daylight light.

[0033] 5, the first white LED 21 may be configured to include a red LED 15, a green LED 17, and a blue LED 19. The light emitted by these LEDs 15, 17, and 19 may be combined to emit white light or the like.

[0034] The second white LED 23 and the yellow LED 33 are also configured to emit warm white, warm white, and yellow light using the same principle as the first white LED 21.

[0035] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment. [Explanation of symbols]
