Like the light emitting portion 2, the grip portion 3 may be formed of a transparent or translucent material, or may be formed of an opaque material.

Further, on the surface of the grip portion 3, an input portion for performing various inputs to the portable light emitting device 1 is provided. In this embodiment, two input units 5a and an input unit 5b are provided. The input unit 5a and the input unit 5b are, for example, a push-type button or a slide-type analog switch.

The input unit 5a is used when performing instruction input for turning on / off the power of the portable light emitting device 1. The input unit 5b is used when performing instruction input for automatically switching the emission color of the portable light emitting device 1. The position, shape, and type of the input unit are not limited to the example of FIG. For example, as a third input unit, a changeover switch for manually switching the emission color may be provided.

== Internal configuration of portable light emitting device ==
As shown in FIG. 2, the portable light emitting device 1 according to the present embodiment includes a light emitting element 10, an acquisition unit 20, and a control unit 30.

[Light emitting element]
The light emitting element 10 is an element that emits light in a predetermined color when a voltage is applied from the battery. The light emitting element 10 is, for example, a semiconductor element such as a light emitting diode (LED). The portable light emitting device 1 according to the present embodiment has a plurality of light emitting elements. Each light emitting element has a different light emitting color. The present embodiment includes three light emitting elements: a red LED 10a that emits red (R) light, a green LED 10b that emits green (G) light, and a blue LED 10c that emits blue (B) light.

The portable light emitting device 1 may include at least two light emitting elements that emit light of different colors. That is, the number of light emitting elements and the light emitting color are not limited to the example of FIG. For example, in addition to (or changing) the above three light emitting elements, a white LED that emits white (W) light or a yellow LED that emits yellow (Y) light may be used. Further, in order to increase the illuminance of the emitted light, a plurality of light emitting elements having the same light emitting color may be provided (for example, two red LEDs 10a, two green LEDs 10b, and two blue LEDs 10c may be provided). Further, the arrangement of each light emitting element in the light emitting unit 2 is not particularly limited.

[Acquisition department]
The acquisition unit 20 receives external light and acquires emission color information based on the color components contained in the received light. The emission color information is information for setting the brightness of the light emitted from the light emitting element. The acquisition unit 20 according to the present embodiment includes a color sensor 21 and an emission color information acquisition circuit 22.

(Color sensor)
The color sensor 21 is a member that receives light outside the portable light emitting device 1 through the opening 4. The color sensor 21 outputs the color signal of the received light to the emission color information acquisition circuit 22.

The color sensor 21 includes a plurality of light receiving units. The light receiving unit can be provided according to the type of light emitted by the light emitting element. The color sensor 21 according to the present embodiment has a first light receiving unit 21a, a second light receiving unit 21b, and a third light receiving unit, depending on the red light, the green light, and the blue light emitted by the light emitting element 10. It has three parts 21c. The first light receiving unit 21a has a light receiving sensitivity peak in the red band. The second light receiving unit 21b has a light receiving sensitivity peak in the green band. The third light receiving unit 21c has a light receiving sensitivity peak in the blue band. That is, the color sensor 21 can detect light in the visible light region (380 nm to 780 nm) by dividing it into RGB color signals.

As such a color sensor 21, a commercially available color sensor (for example, an RGB color sensor manufactured by Hamamatsu Photonics Co., Ltd.) can be used. When a red LED, a green LED, a blue LED, and a white LED are used as the light emitting element 10, in addition to the above-mentioned light receiving unit that detects RGB color signals, the light receiving sensitivity is applied to the white band (the entire visible light region). A color sensor having a light receiving unit can be used.

(Emission color information acquisition circuit)
The emission color information acquisition circuit 22 acquires emission color information of a predetermined color component based on the color signal of the light in each band received by the color sensor 21. The emission color information acquisition circuit 22 outputs the acquired emission color information to the control unit 30.

In the present embodiment, the color sensor 21 detects a color signal of light in the RBG band. The emission color information acquisition circuit 22 acquires emission color information of a red component, a green component, and a blue component based on these color signals. The emission color information is acquired as, for example, a numerical value determined in the range of 0 to 100 for each color component.

[Control unit]
The control unit 30 performs various controls on the portable light emitting device 1. The control unit 30 includes a CPU 30a and a memory 30b. The control unit 30 controls the operation of the light emitting element 10 and the acquisition unit 20 based on, for example, instruction input from the input unit 5a and the input unit 5b. Further, the control unit 30 sets the brightness of the light emitted by the light emitting element 10 based on the acquired emission color information, and controls the light emission and the light emission stop of the light emitting element 10.

In the present embodiment, the control unit 30 sets the brightness of the light emitted by the red LED 10a based on the acquired emission color information of the red component, and the green LED 10b sets the brightness of the light emitted by the green LED 10a based on the acquired emission color information of the green component. The brightness of the emitted light is set, and the brightness of the light emitted by the blue LED 10c is set based on the acquired emission color information of the blue component.

For example, when "R: G: B = 25: 85: 50" is input as the emission color information, the control unit 30 sets the brightness of each LED to "red LED: green LED: blue LED = 25: 85: It is set at a ratio of "50", and each LED is made to emit light at the set brightness. The light emitted by each LED is mixed and emitted from the light emitting unit 2 as a predetermined color (a color in which RBG is mixed at the above ratio).

== How to use the portable light emitting device ==
Next, a specific method of using the portable light emitting device 1 according to the present embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing the operation of the portable light emitting device 1. In this example, each of the user U1 and the user U2 who are watching the artist's live performance in the audience seats of the concert hall owns the portable light emitting device 1. User U1 and user U2 may or may not be acquainted, but user U1 is sitting next to user U2. Further, it is assumed that the portable light emitting device 1 owned by the user U1 emits light of the emission color L, while the portable light emitting device 1 owned by the user U2 does not emit light of any color. This is because, for example, the user U1 is familiar with the operation of the portable light emitting device 1 in the live concert and the setting content (directing content) of the light emitting color according to the progress of the music, but the user U2 is familiar with the setting content (directing content) of the portable light emitting device 1. This is a case where the user is unfamiliar with the operation and does not understand the content of the production.

The user U2 first inputs an instruction for switching the emission color via the input unit 5b of his / her portable light emitting device 1 (instruction input for switching the emission color. Step 10). Based on the instruction input, the control unit 30 drives the acquisition unit 20.

After that, the user U2 directs the opening 4 of his / her portable light emitting device 1 toward the portable light emitting device 1 side of the user U1 and causes the portable light emitting device 1 to receive the light of the emission color L.

The color sensor 21 receives the light of the emission color L for each band by the first light receiving unit 21a to the third light receiving unit 21c (receives external light. Step 11). The color sensor 21 outputs the received light color signal of each band to the emission color information acquisition circuit 22 (outputs the color signal of each band. Step 12).

The emission color acquisition circuit 22 acquires emission color information of each color component based on the color signal output in step 12 (acquisition of emission color information. Step 13). The emission color acquisition circuit 22 outputs the acquired emission color information to the control unit 30.

The control unit 30 sets the brightness of the light emitted by the red LED 10a, the green LED 10b, and the blue LED 10c based on the emission color information acquired in step 13 (setting the brightness of the light emitting element. Step 14).

Then, the control unit 30 causes the red LED 10a, the green LED 10b, and the blue LED 10c to emit light so as to have the brightness set in step 14 (light emission of the light emitting element. Step 15).

As described above, the portable light emitting device 1 according to the present embodiment includes a plurality of light emitting elements 10, an acquisition unit 20 that receives external light and acquires emission color information based on a color component contained in the received light. It has a control unit 30 that sets the brightness of the light emitted by the light emitting element 10 based on the acquired emission color information and controls the light emission and the light emission stop of the light emitting element 10. More specifically, the plurality of light emitting elements 10 include at least a red LED 10a, a green LED 10b, and a blue LED 10c. The acquisition unit 20 has at least a first light receiving unit 21a having a light receiving sensitivity peak in the red band, a second light receiving unit 21b having a light receiving sensitivity peak in the green band, and a third light receiving unit 21b having a light receiving sensitivity peak in the blue band. The emission color information acquisition circuit 22 that acquires the emission color information of at least the red component, the green component, and the blue component based on the color sensor 21 including the light receiving unit 21c of the above and the color signal of the light in each band received by the color sensor 21. And have. The control unit 30 sets the brightness of the light emitted by the red LED 10a based on the acquired emission color information of the red component, and determines the brightness of the light emitted by the green LED 10b based on the acquired emission color information of the green component. The brightness of the light emitted by the blue LED 10c is set based on the acquired emission color information of the blue component.

According to such a portable light emitting device 1, only by receiving light from another user's portable light emitting device 1 that has already emitted light in a predetermined color, another user automatically uses his / her own portable light emitting device 1. It is possible to emit light in the same color as the portable light emitting device 1 of the above. Therefore, even a user who is unfamiliar with the operation of the portable light emitting device 1 or a user who cannot grasp the content of the effect can appropriately switch the light emitting color of the portable light emitting device 1. That is, according to the portable light emitting device 1 according to the present embodiment, the emission color can be switched appropriately and easily.

In the above example, an example of starting the switching of the emission color based on the instruction input by the input unit 5b has been described, but the present invention is not limited to this. For example, when the power is turned on, even if there is no switching instruction input, the acquisition unit 20 acquires the emission color information only when the light of a predetermined brightness or higher is received, and the emission color information is acquired. The control unit 30 may switch the emission color based on the color information. As a result, the opening 4 can be made to emit light in the same color as the portable light emitting device 1 of the other user simply by bringing the opening 4 close to the portable light emitting device 1 of the other user who is emitting light. Alternatively, the switching instruction is input once, the brightness received at that time is stored as the above-mentioned predetermined brightness, and thereafter, the opening 4 emits light each time it approaches the portable light emitting device 1 of another user who is emitting light. Colors may be switched.

Further, in the middle of the production or the like, the emission color may be switched while the portable light emitting device 1 has already emitted light. In this case, there is a possibility that the light itself emitted by the self-portable light emitting device 1 will be received. Therefore, when the control unit 30 receives an instruction input for switching the emission color from the input unit 5b while the light emitting element 10 emits light, the control unit 30 stops the light emission of the light emitting element 10 and then emits the brightness of the light emitted by the light emitting element 10. Is set, and it is preferable to make the light emitting element 10 emit light again. In this case, since the light itself emitted by the own portable light emitting device 1 is not received, the desired light (light emitted by the portable light emitting device 1 of another user) can be received more reliably.

Further, as in the above example, the number of light receiving units and the type of light emitted by the light emitting element do not necessarily have to correspond one-to-one. For example, when a red LED, a green LED, a blue LED, and a yellow LED are used as the light emitting element 10, a color sensor 21 that detects a color signal of three RGB colors may be used. In this case, the emission color information acquisition circuit 22 refers to a predetermined table set in advance and acquires emission color information of each color component of RGBY based on the RGB color signal. The predetermined table associates the output value of the color signal from the color sensor 21 with the luminance of RGBY. For example, the luminance of Y is determined based on the color signal of R and the color signal of G. NS.

The above embodiment is presented as an example and does not limit the scope of the invention. The above configurations can be implemented in appropriate combinations, and various omissions, replacements, and changes can be made without departing from the gist of the invention. The above-described embodiments and modifications thereof are included in the scope and gist of the invention, as well as in the scope of the invention described in the claims and the equivalent scope thereof.
