The direction in which the leads 26a and 26b of the LEDs 18a to 18d are bent may be opposite to the predetermined direction (directions indicated by arrows P, Q, R, and S in FIG. 3).

  Next, with reference to FIG. 1, the display apparatus 2 which assembled | attached the circuit board body 12 comprised as mentioned above is demonstrated. First, corresponding to the shape of the curved one side wall 40a of the casing 4, the board body 14 of the circuit board body 12 is bent by manual work or the like, and the circuit is made using a double-sided tape or an adhesive (not shown). The other surface (the surface on the side where the LED 18 is not attached) of the substrate body 12 of the substrate body 12 is attached to the inner surface of one side wall 40 a of the casing 4. Similarly, the light source 8 is housed in the housing space 6 of the casing 4 by attaching the board body 14 of the circuit board body 12 to the inner surface of the other curved side wall 40 b of the casing 4. Thus, in a state where the light source 8 is housed in the housing space 6 of the casing 4, the light emitting portion 38 of each LED 18 faces the opening 10 of the casing 4. Note that a transparent glass plate, a diffuse transmission plate (not shown), or the like may be attached to the opening 10 of the casing 4. In FIG. 1, the wiring pattern 16 provided on the substrate body 14 is not shown.

  Next, with reference to FIG.5 and FIG.6, the illumination method by the display apparatus 2 of this embodiment is demonstrated.

Irradiated outside through a defined space. Therefore, the light from the light source 8 is irradiated in the irradiation region 44 indicated by the one-dot chain line in FIG. 6 from between the outer peripheral portion of the casing 4 (that is, the side walls 40a and 40b and the end wall 48) and the mounting wall 42. The outline of the English letter “C” emerges due to the light from the light source 8. By appropriately combining this display device 2 with a display device (not shown) having a casing formed in the shape of another English character, it is possible to configure advertising characters such as “COFFEE”. It becomes.

  Here, when the optical axis of each LED 18 attached to the substrate body 2 is substantially parallel to the axis C as in the LED 18 a shown in FIG. 3, the light is emitted from the end 46 of the casing 4 of the display device 2. The illuminance of light is lower than the illuminance of light irradiated from other parts of the casing 4, so that uniform illuminance cannot be obtained over the entire outer periphery of the casing 4 of the display device 2. Therefore, as described above, by selectively attaching the other lead 26b of the LED 18 to any one of the plurality of second attachment holes 24a to 24d, the optical axis direction of the LED 18 disposed at the end 46 of the casing 4 May be adjusted as appropriate. For example, as shown in FIG. 4, by attaching the other lead 26b of the LED 18 arranged at the end 46 of the casing 4 to the second mounting hole 24b, the optical axis direction of the LED 18 is predetermined with respect to the axis C. The direction is inclined at an angle α. Thereby, the optical axis of the LED 18 is inclined toward the end wall 48 side of the casing 4, and the light from the LED 18 is irradiated from the end portion 46 of the casing 4, so that the illuminance of light at the end portion 46 of the casing 4 is reduced. It becomes possible to raise.

  Alternatively, the other lead 26b of the LED 18 may be attached to any of the second attachment holes 24a, 24c, or 24d, and depending on the shape of the casing 4, the illuminance of light at the end portion 46 of the casing 4, etc. What is necessary is just to select suitably the 2nd attachment holes 24a-24d which attach the other lead | read | reed 26b. Further, the other lead 26b of each LED 18 disposed in a portion other than the end 46 of the casing 4 is selectively attached to any one of the second attachment holes 24a, 24c, 24d, and the optical axis direction of these LEDs 18 is adjusted. You may make it set suitably.

Since the LEDs 18 are respectively attached to both surfaces of the substrate body 14A, the light from the light source 8A is efficiently irradiated from the outer peripheral portion of the casing 4A.

  When the illuminance of light at the end (not shown) of the casing 4A is low, the other lead 26b of the LED 18 disposed at the end of the casing 4A is connected to the plurality of second mounting holes 50a as in the above embodiment. The optical axis direction of the LED 18 can be appropriately changed by selectively attaching to any one of ˜50f. Thereby, the illuminance of light irradiated from the entire outer peripheral portion of the casing 4A can be made uniform.

  In this other embodiment, since the number of the second mounting holes 50a to 50f is larger than that of the second mounting holes 24a to 24d of the above embodiment, the optical axis direction of the LED 18 can be set more finely. It is possible to finely adjust the illuminance of light emitted from the end of the casing 4A.
