(Configuration example of light-emitting device)
First, with reference to FIGS. 1 to 6, the functional configuration and configuration example of a light-emitting device D1 according to the present embodiment will be described.

Here, FIG. 1 is a functional block diagram showing the functional configuration of the light-emitting device D1, FIG. 2 is a front view showing a configuration example of the light-emitting device D1, and FIG. 3 is a front view showing another configuration example of the light-emitting device D1. 4 is a side partial cross-sectional view showing a configuration example of the light-emitting device D1, FIG. 5 is a partially enlarged cross-sectional view showing a configuration example of the light-emitting device D1, and FIG. 6 is another configuration example of the light-emitting device D1. It is a side partial cross-sectional view showing.

A portable light-emitting device D1 that improves entertainment by being held and shaken by spectators in time with music or singing at a concert venue or the like, has a light-emitting element (for example, three colors ( R, G, B) light-emitting type LEDs, etc.), a light guide section that guides the light emitted from the light-emitting section 100, and a one-chip microcomputer that controls the light emission color or light emission pattern of the light-emitting section 100. and a control unit 101 composed of

The light guide section is composed of a flat light guide plate 300A (300B) made of, for example, transparent resin or glass.

The light guide plate 300A (300B) is formed into various shapes such as a circle (see FIG. 2) and a star shape (see FIG. 3) by Thomson processing or laser cutting.

At least one of characters (for example, "LUMC" etc.) 301, a symbol, a figure or a pattern is provided on one of the surfaces of the light guide plate 300A (300B).

As a result, it is possible to improve the decorativeness and expressiveness by displaying characters, symbols, figures, or patterns 301 compared to a light emitting device having a rod-shaped light guide, and to enhance the entertainment at a concert or the like.

Characters, symbols, figures or patterns 301 are formed on the surface of the light guide plate 300A (300B) by etching (for example, by a dry method such as laser etching or a wet method using chemicals) or by printing using a printer. formed by

As a result, it is possible to display, for example, contents related to concerts, names of sponsors, logos, etc., on the surface of the light guide plate 300A (300B), thereby enhancing the entertainment value of concerts and the like, as well as enhancing the effectiveness of advertising. can.

Further, as shown in FIG. 5, a character, symbol, figure, pattern, or the like 301 can be formed by a set of fine irregularities 311 and 312 .

As a result, the light emission L1 from the light emitting unit 100 is scattered by the assembly of the fine unevennesses 311 and 312, so that the formed characters, symbols, figures or patterns 301 are visually recognized as if they are floating, which enhances entertainment at concerts and the like. can be further enhanced.

Further, a light receiving element 102 such as a phototransistor is further provided, and the control section 101 controls the light emission color (R, G, B) or the light emission pattern of the light emitting section 100 based on the control signal received by the light receiving element 102. can be done.

As a result, for example, the organizer of a concert or the like can easily control the light emission color and light emission pattern of each light emitting device D1, thereby further enhancing entertainment.

2 and 3, the light receiving element 102 can be configured to receive the control signal IR via the light guide plate 300A (300B). Note that the control signal IR can be transmitted from the external control device 200 or the like (see FIG. 1).

As a result, there is no need to separately provide a portion through which the control signal IR passes, and since the light guide plate 300A (300B) is always exposed, the control signal IR can be reliably received.

Also, the light receiving element 102 can be composed of an infrared detection element, in which case the control signal is transmitted using infrared rays as a carrier wave.

As a result, it is possible to reliably receive the control signal IR using infrared rays as a carrier wave without being interfered by the visible light L1 emitted from each light-emitting device D1 and the light beams used for performance at a concert or the like.

It should be noted that the communication of the control signal may be performed by electromagnetic waves other than infrared rays or wired communication.

As shown in FIGS. 2 and 3, a light emitting unit 100, a control unit 101, a light receiving element 102, and a power supply unit (battery) 103 for supplying power to each unit are housed in a housing 400 made of resin or the like. there is

An engaging portion 302 that engages with the upper end of the housing 400 is formed at the lower end of the light guide plate 300A (300B), and is fixed to the housing 400 with screws or the like (not shown).

On the surface side of the housing 400, button switches 105a to 105c for turning on/off the power and for selecting the emission color and emission pattern are provided.

Further, as shown in FIG. 6, characters 301a and patterns 301b may be provided on both sides of the light guide plate 300A (300B). Although FIG. 6 shows an example in which characters 301a and patterns 301b provided on both sides are arranged at symmetrical positions, they may be arranged at asymmetrical positions.

(light emission control processing)
Next, with reference to the flowchart of FIG. 7 and the explanatory diagram of FIG. 8, the processing procedure of the light emission control processing executed by the control unit 101 of the light emitting device D1 according to the present embodiment will be described.

As shown in FIG. 7, first, when the power is turned on in step S10, the LED of the light emitting unit 100 is turned on in step S11. In addition, when a three-color (R, G, B) emitting LED is used as the light emitting unit 100, the emitting color and the emitting pattern may be set as initial values.

In step S12, it is determined whether or not the light receiving element 102 has received the control signal IR. If "No", the same processing is continued, and if "Yes", the process proceeds to step S13.

In step S13, the light emission color of the LED of the light emitting unit 100 is changed based on the control signal IR, and the process proceeds to step S14.

In step S14, the light emission pattern of the LED of the light emission part 100 is changed based on the control signal IR, and it transfers to step S15.

In step S15, it is determined whether or not the power has been turned off. If "No", the process returns to step S12 to repeat the same process, and if "Yes", the process ends.

FIGS. 8A to 8C are explanatory diagrams showing transition states of light emission of the light-emitting device D1 according to the present embodiment.

In the examples shown in FIGS. 8A to 8C, each time the control signal IR is received, the emission color of the LED of the light emitting unit 100 transitions from R (red) to G (green) to B (blue). indicate the case. Note that the change pattern of the emitted light color is not limited to this, and can be changed as appropriate. Alternatively, a plurality of LEDs may be used to express intermediate colors. Also, for each luminescent color, the luminescent pattern can be changed by appropriately changing the lighting interval.

As described above, the light-emitting device of the present invention has been described based on the illustrated embodiments, but the present invention is not limited to this, and the configuration of each part can be replaced with an arbitrary configuration having similar functions. can.
