Next, the attaching / detaching operation of the display plate and the diffusion plate according to the information display illumination device of the first embodiment of the present invention will be described with reference to FIG.

[First Embodiment]
First, the configuration of the information display lighting device 1 according to the first embodiment of the present invention will be specifically described with reference to FIGS. 1 to 8.

  As shown in FIGS. 1 and 3, for example, the information display lighting device 1 includes a display unit 10 on which predetermined information is represented and a light guide unit provided with a pattern for deriving diffused light toward the display unit 10. 20, a light source unit 30 provided with a light source 31 that emits light toward the light guide unit 20, and a housing unit 40 that houses the display unit 10, the light guide unit 20, and the light source unit 30. Composed. Hereinafter, the display unit 10, the light guide unit 20, the light source unit 30, and the housing unit 40 constituting the information display lighting device 1 will be described.

  The display unit 10 constituting the information display lighting device 1 represents predetermined information. For example, as shown in FIG. 1C, such a display unit 10 includes at least a protection plate 11, a display plate 12, and a diffusion plate 13, and includes a display plate urging member 14, a fixing plate 15, and a fixing member 16. Can be provided. Hereinafter, the configuration of the display unit 10 will be described. The protection plate 11 protects the display plate 12 described later from dust and the like, and for example, an acrylic plate or a glass plate is used. The display board 12 is appropriately prepared by the user of the information display lighting device 1 and corresponds to, for example, an OHP film or paper material on which predetermined information is represented. Here, the predetermined information on the display board 12 is, for example, the contents of a seminar held at the exhibition hall, a list of groceries sold at a department store, or the arrival time of a train used in a station. The display board 12 may be a plain OHP film provided as an accessory to the information display lighting device 1, and a user of the information display lighting device 1 may repeatedly write and use predetermined information reproducibly. good. The diffusion plate 13 further diffuses diffused light derived from the light guide unit 20 described later, and irradiates the diffused light onto the display plate 12 as a uniform surface light source. For example, a milk half plate is used. .

  Moreover, regarding the display unit 10 constituting the information display lighting device 1, for example, as shown in FIGS. 5 and 1C, the display plate urging member 14 urges the display plate 12 against the diffusion plate 13. A magnet plate having magnetism different from that of the fixing plate 15 described later is used. In FIG. 5A, illustration of the protection plate 11, the display plate 12, and the display plate urging member 14 shown in FIG. 5B is omitted. Further, the fixing plate 15 diffuses the display plate 12 by fixing the diffusion plate 13 to the urging portion 52A of the light guide portion urging member 52 and attracting the display plate urging member 14 provided opposite to the magnetic plate by a magnetic force. The plate 13 is energized. Such a fixing plate 15 is made of, for example, iron and formed in a plate shape, and is attached to a cutout portion 13A formed by cutting out a part of the end portion of the diffusion plate 13. The fixing member 16 is a member for joining the fixing plate 15 to the urging portion 52A of the light guide portion urging member 52 via the diffusion plate 13, and specifically, for example, a screw, and the light guide portion. Screwed into a screw groove 52C formed in the biasing portion 52A of the biasing member 52.

  Moreover, regarding the display unit 10 constituting the information display lighting device 1, for example, as shown in FIG. 6, the display plate 12 is fixed detachably in a state where the display plate 12 is biased with respect to the diffusion plate 13 using a hook 17.

Specifically, the hook 17 is detachably fixed in a state where the display plate 12 is biased with respect to the diffusion plate 13, and is made of, for example, plastics and is formed in a substantially U-shape. . Such a hook 17 is inserted in the direction of the arrow in FIG. 6B with respect to the light guide plate 13, and then the fixing member 16 is layered through a hole 13 </ b> B formed at the end of the diffusion plate 13 to form a screw groove 52 </ b> C. The light guide unit urging member 52 is fixed together with the diffusion plate 13 by being screwed to the light guide unit. Here, since the thickness inside the hook 17 is larger than the thickness of the diffusion plate 13, a gap is generated between the left side of the diffusion plate 13 and the hook 17 shown in FIG. By inserting the display plate 12 into the gap, the display plate 12 can be detachably fixed in a state where the display plate 12 is biased with respect to the diffusion plate 13.
