[First Embodiment]
As shown in FIG. 1, the reception stand device 1 according to the present invention uses a plurality of light guide plates 30 to emit high-intensity light having various light distribution characteristics in a three-dimensional manner over a wide range. The surroundings can be illuminated. Hereinafter, the configuration of the reception stand device 1 according to the present invention will be specifically described with reference to FIGS. 1 to 6.

  A plurality of light emitting units 10 are held in a casing unit 50 described later. Emits light in a planar shape. Such a light emitting unit 10 includes a light source 20 provided in a linear shape and a light guide 10 configured to derive light from the light source 10 that is formed in a plate shape and is incident from the incident surface 30e from the main surfaces 30a and 30b adjacent to the incident surface 30e. An optical plate 30 and a connecting member 40 that holds the light source 20 and the light guide plate 30 are provided. Hereinafter, each structure of the light emission part 10 is demonstrated in order.

  For example, as illustrated in FIG. 4, the light source 20 of the light emitting unit 10 extends linearly.

  Such a light source 20 includes a plurality of LEDs 21 and a substrate 22 on which the plurality of LEDs 21 are mounted at a predetermined interval. Hereinafter, each component of the light source 20 provided in the reception desk device 1 will be described in order. The LEDs 21 of the light source 20 are made up of surface-mounted light emitting diodes (LEDs), and a plurality of LEDs 21 are mounted on a substrate 22 described later at a predetermined interval. Here, the emission wavelength of the LED 21 is selected from wavelengths corresponding to any one of white, red, orange, yellow, green, blue, indigo and purple in the visible light region. Further, the light emission wavelength of the LED is not limited to the visible light region, and may be configured to generate and derive fluorescence in the visible light region with the light guide plate 30 described later after selecting the wavelength in the ultraviolet region. . Instead of the LED 21, an organic light emitting diode, a fluorescent tube, a cold cathode tube, an incandescent lamp, a neon tube, or the like may be used. Moreover, you may provide LED21 of a different light emission wavelength in the some light-guide plate 30 mentioned later. The substrate 22 of the light source 20 is made of a glass epoxy substrate formed in a plate shape, and a plurality of LEDs 21 are mounted at a predetermined interval. Here, the shape of the substrate 22 is equal to or slightly shorter than the shape of the incident surface 30e of the light guide plate 30 described later. In addition, a wiring (not shown) is soldered to an electrode provided on the substrate 22, and driving power is supplied to the plurality of LEDs 21 from the outside through the wiring.

  For example, as shown in FIG. 4, the light guide plate 30 of the light emitting unit 10 has a plate-like shape, and one main surface 30a that is a main surface adjacent to the incident surface 30e and the other main surface 30e. Derived from the surface 30b.

  As shown in FIGS. 4 and 5, the light guide plate 30 is made of a resin plate that is transparent in the visible light region, such as an acrylic resin or a polycarbonate formed by polymerizing acrylic acid or methacrylic acid. The light guide plate 30 is formed in a large and long plate shape, and a light incident surface 30e is formed on one side in the short direction. Here, the light of the LED 21 incident from the incident surface 30e of the light guide plate 30 propagates through the inside of the light guide plate 30, and then is derived from the inside of the light guide plate 30 to the outside through the one main surface 30a and the other main surface 30b. Is done. Furthermore, concave portions 30c that guide the light of the LEDs 21 as diffused light are formed in a matrix on one main surface 30a of the light guide plate 30. Similarly, in the other main surface 30b of the light guide plate 30, concave portions 30d for guiding the light of the LEDs 21 as diffused light are formed in a matrix. The positions of the recesses 30c formed in a matrix on one main surface 30a of the light guide plate 30 and the recesses 30d formed in a matrix on the other main surface 30b are relatively shifted by a half pitch. Here, most of the diffused light generated in the plurality of concave portions 30c formed on the one main surface 30a of the light guide plate 30 is derived from the other main surface 30b of the light guide plate 30 as light of substantially uniform surface emission. Similarly, most of the diffused light generated in the plurality of concave portions 30d formed on the other main surface 30b of the light guide plate 30 is led out from one main surface 30a of the light guide plate 30 as substantially uniform surface emitting light. Moreover, the some light-guide plate 30 shown in FIG.1 and FIG.2 is arrange | positioned at the basically same angle along the connection member 40 mentioned later. However, the present invention is not limited to such a configuration. As shown in FIG. 6A, a plurality of light guide plates 30 are arranged at different angles with respect to the adjacent light guide plates 30. Also good. Similarly, as shown in FIG. 6B, a plurality of light guide plates 30 may be arranged at different angles at random.

  The depth of the concave portion 30c of the one main surface 30a of the light guide plate 30 and the depth of the concave portion 30d of the other main surface 30b may be formed so as to be deeper each time the light guide plate 30 is separated from the incident surface 30e. By forming the concave portion 30c and the concave portion 30d in this manner, the light amount of the LED 21 incident from the incident surface 30e of the light guide plate 30 is separated from the incident surface 30e even if the light amount of the LED 21 decreases every time it is separated from the incident surface 30e. Since the shape of the recessed part 30c and the recessed part 30d becomes large each time, the reduction | decrease in the light quantity of the diffused light which generate | occur | produces in the recessed part 30c and the recessed part 30d can be suppressed. Therefore, even when the light guide plate 30 is large and long and the LEDs 21 are arranged in the short direction of the light guide plate 30, the light guide plate 30 is guided regardless of the distance from the incident surface 30 e of the light guide plate 30. Uniform surface emission can be derived from one main surface 30a and the other main surface 30b of the light plate 30. Further, even if the convex portions are formed in a matrix on one main surface 30a and the other main surface 30b of the light guide plate 30, diffused light can be generated as in the case where the concave portions are formed in a matrix. Moreover, although the light guide plate 30 has been described as a transparent resin plate in the visible light region, a resin plate colored in blue or red may be used. The light guide plate 30 may be a resin plate to which a fine particle diffusion member that emits diffused light when irradiated with light is added. Further, the light guide plate 30 may be a resin plate coated or added with a fluorescent agent that emits fluorescence when irradiated with light in the ultraviolet region or visible light region. In addition, about the light-guide plate 30 shown by FIG.1, FIG.2 and FIG.6, in order to prevent that description becomes detailed and discrimination | determination of each structure of this invention is prevented, the recessed part is abbreviate | omitted, respectively.
