  Here, FIG. 1 is a functional block diagram showing a 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, FIG. 4 is a partial side sectional view showing a configuration example of the light emitting device D1, FIG. 5 is a partially enlarged 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. FIG.

  In a concert hall or the like, a portable light-emitting device D1 that improves entertainment by swinging the hand of the audience with the music or singing in accordance with music or singing as shown in FIG. R, G, B) a light emitting unit 100 including a light emitting type LED, a light guide unit for guiding light emitted from the light emitting unit 100, a one-chip microcomputer for controlling a light emitting color or a light emitting pattern of the light emitting unit 100, and the like. And a control unit 101 composed of

  The light guide section is formed 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 (see FIG. 3) by Thomson processing or laser cutting.

  On one surface of the light guide plate 300A (300B), at least one of a character (for example, “LUMC”) 301, a symbol, a graphic, or a pattern is provided.

  Thereby, compared to the light emitting device having the rod-shaped light guide, the decorativeness and the expressiveness by displaying the character, the symbol, the graphic, or the pattern 301 can be improved, and the entertainment at a concert or the like can be improved.

  The characters, symbols, figures, patterns, etc. 301 are etched on the surface of the light guide plate 300A (300B) (for example, by a dry method such as laser etching or a wet method using a chemical) or a printing process using a printer. Formed by

  Thereby, for example, contents related to a concert or the like, a sponsor name, a logo, or the like can be displayed on the surface of the light guide plate 300A (300B). it can.

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

  As a result, the light L1 from the light emitting unit 100 is scattered by the set of the fine irregularities 311 and 312, so that the formed character, symbol, figure or pattern 301 is visually recognized as if it emerges, and the entertainment in a concert or the like is improved. Can be further enhanced.

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

  Thereby, 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 to further enhance the entertainment property.

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

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

  Further, the light receiving element 102 can be constituted by an infrared detecting element, and in that case, the control signal is transmitted using infrared light as a carrier.

  This makes it possible to reliably receive the control signal IR using infrared light as a carrier wave without being interfered by the visible light L1 emitted from each light emitting device D1 and light rays for staging in a concert or the like.

  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 formed of resin or the like. I have.

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

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

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

(Emission control processing)
Next, with reference to a flowchart of FIG. 7 and an explanatory diagram of FIG. 8, a processing procedure of a light emission control process 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. When a three-color (R, G, B) light emitting LED is used as the light emitting unit 100, a light emitting color and a light 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 process 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 emitting pattern of the LED of the light emitting unit 100 is changed based on the control signal IR, and the process proceeds 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, and the same process is repeated. 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 changes from R (red) to G (green) to B (blue). Show the case. The emission color change pattern is not limited to this, and can be changed as appropriate. Further, a plurality of LEDs may be used to express an intermediate color. Further, for each emission color, the emission pattern in which the lighting interval is appropriately changed can be changed.

  As described above, the light emitting device of the present invention has been described based on the illustrated embodiment. However, the present invention is not limited to this, and the configuration of each unit may be replaced with any configuration having the same function. it can.
