Description

  The present invention relates to a self-luminous display unit, and more particularly to a unit that does not require complicated processing of a plate or the like and that allows a light-emitting element to be easily attached.

  For example, it is common for single-family houses and apartment buildings to have nameplates at the gates and entrances, but a self-luminous display unit with a built-in light source has been proposed to ensure that the letters on the nameplate can be recognized at night. (Patent Document 1).

  However, the method of projecting the nameplate from the outside requires a light source with a large amount of light, for example, a fluorescent lamp or a light bulb, which not only increases the size of the display unit, but also breaks down the bulb in the case of a fluorescent light or a light bulb Therefore, maintenance inspection (maintenance) is required.

  On the other hand, although LED (light emitting diode) has low luminance, it requires less layout space, consumes less power, has a longer life, and has great advantages in energy saving and maintenance.

Therefore, a self-luminous display unit has been proposed in which the light of the LED is incident from the side surface of the nameplate so that the entire faceplate emits light (PTL 2 and PTL 3).

  However, in the self-luminous display unit described in the above-mentioned patent document, it is necessary to provide a recess for housing the LED in the nameplate plate, and there is a problem that the processing of the plate of the nameplate and the mounting of the LED are complicated.

  The present invention has been made in view of such problems, and an object thereof is to provide a self-luminous display unit that does not require complicated plate processing or the like and can be easily mounted with LEDs.

  Therefore, the self-luminous display unit according to the present invention is composed of a transparent or translucent material, characters and / or designs are displayed, and a display plate having a screw hole penetrating through the front and back surfaces, The display plate is attached to the fixed structure by being inserted into the screw hole, and a window portion is opened at a portion facing the inner surface of the screw hole, and the element hole communicates with the window portion along the axis. And a light-emitting element that is inserted into the element hole of the mounting screw and allows light to enter from the window portion toward the inside of the display plate.

  One of the features of the present invention is that an element hole is formed along the axis on a mounting screw for attaching the display plate to the fixed structure portion, and a window is formed in the element hole to allow light to enter the display plate. It is in the point which enabled it.

  This eliminates the need for complicated processing of forming a light-emitting element, for example, a recess for housing the LED, on a plate such as a nameplate, and allows the LED to be easily attached.

  The display plate may be directly attached to a fixed structure portion such as a gate pillar or a front door, or may be attached to a base plate attached to the gate pillar or the front door with a mounting screw. That is, the fixed structure portion can be a base plate.

  In addition, a film on which characters and / or designs are printed may be attached to the display plate. However, if characters and / or designs are engraved on the display plate, the characters and / or designs will be reflected in the light of the light emitting element. Even more preferred.

  The material of the display plate and the base plate is not particularly limited. For example, transparent or translucent glass or plastic can be used for the display plate. The base plate can be made of terracotta, wood, metal material, and other materials.

  The present invention is very effective when applied to a nameplate, but can also be applied to a signboard. Moreover, LED and other elements can be used as the light emitting element.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 4 show a preferred embodiment of a self-luminous display unit according to the present invention. In the figure, a display plate 11 is attached via a spacer 12 to a base plate 10 which is a fixed structure portion.

  This base plate 10 is manufactured in a square plate shape using terracotta, wood, metal material, etc., and screw holes 10A are formed through the front and back surfaces at the four corners of the base plate 10, and on the back side of the screw holes 10A. An enlarged step portion is formed so that the head of the mounting bolt (mounting screw) 13 is prevented from rotating.

  The display plate 11 is manufactured in a rectangular plate shape using transparent glass. Screw holes 11A are formed at the four corners of the display plate 11, and a plurality of characters, for example, characters indicating a nameplate are engraved on the display plate 11. It is installed.

  The mounting bolts 13 are inserted into the screw holes 10A and 11A of the base plate 10 and the display plate 11 and the insertion holes of the spacer 12 and are screwed into the cap nuts 14, whereby the display plate 11 attaches the spacer 12 to the base plate 11. It is attached via.

  A window portion 13A is formed in the mounting bolt 13 at a portion facing the inner surface of the screw hole 11A of the display plate 11, and an element hole 13B is formed along the axis and in communication with the window portion 13A. .

  An LED (light emitting element) 16 is inserted into the element hole 13B of the mounting bolt 13 and is held at a position where the LED 16 is inserted by an appropriate member, for example, a plug member (not shown). The light of the LED 16 is incident on the display plate 11 from the window portion 13A.

  Thus, the complicated process of forming a recess for housing the LED 16 in the display plate 11 is not required, and the LED 16 can be easily mounted using the mounting bolt 13.

  Note that the mounting bolt 13 may be waterproofed using silicon resin or the like in order to avoid the LED 16 from being wet by rainwater. Further, the control device may be a commercial power source or a solar cell as a power source. In particular, when a solar cell is used as a power source, the necessity for maintenance can be reduced.

  Further, the LEDs 16 at the four corners of the display plate 11 may be a single color, or may emit a plurality of colors, for example, RGB colors, and three LEDs that emit, for example, RGB colors are inserted into each element hole. In this way, if colors of RGB are emitted in this way, it is possible to produce all colors.
