  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 and 2 show a light decoration device 1 according to the first embodiment. The light decoration device 1 includes a base 10, an LED light source unit 12, and a decoration plate 14. The base 10 is a box-shaped member obtained by stainless steel molding, and the LED light source unit 12 can be accommodated therein.

  As shown in FIGS. 3 and 4, a groove-like recess 20 is formed on the upper surface 10 </ b> A of the base 10, and the decorative plate 14 is inserted into the groove-like recess 20. The LED light source unit 12 includes a circuit board 30 larger than the opening area of the groove-shaped recess 20 and a plurality of LEDs 32 arranged in a row with respect to the circuit board 30. More specifically, the bullet-shaped LEDs 32 are laid in parallel so that the area of the opening 20A of the groove-shaped recess 20 is satisfied, so that these LEDs 32 face the bottom surface of the groove-shaped recess 20. . The LED light source unit 12 is fixed by a support 11 in the base 10. Note that the timing and intensity of light irradiation of the LED 32 are controlled by a control device 34 installed beside the circuit board 30. Although the power supply is not particularly shown here, it may be supplied from an external general-purpose power supply through wiring, or a battery may be housed and supplied inside the base 10.

  As a result, the bottom surface of the groove-shaped recess 20 is formed by a plane in which the protruding ends of the plurality of LEDs 32 are connected. Further, a light reflecting surface 20 </ b> C is formed on the inner peripheral wall 20 </ b> B of the groove-shaped recess 20. The light reflecting surface 20C reflects the light of the LED 32. In this embodiment, a cylindrical metal material (for example, aluminum or stainless steel) is used as the inner peripheral wall 20B, and the inner peripheral wall 20B is mirror-finished to form the light reflecting surface 20C. In addition to mirror finishing the metal material, a light reflecting surface may be formed by metal vapor deposition or plating, or a light reflecting film may be attached.

In detail, the decorative plate 14 includes a rod-shaped illumination unit 40, a leg unit 42, and a decorative unit 44, which are continuously formed as an integral member. The rod-shaped illumination unit 40 is a rod-shaped member having a square cross section, is accommodated in the groove-shaped recess 20 and is fixed by the inner peripheral wall 20B and the like. Further, the bar-shaped illumination unit 40 includes a light emission surface 40A having substantially the same size as the opening 20A of the groove-shaped recess 20, and transmits light from the LED 32 disposed at the bottom of the groove-shaped recess 20 to emit light. It discharges to the outside (upward) through the surface 40A. In particular, in the light decoration device 1 according to the present embodiment, the entire bar-shaped illumination unit 40 is embedded in the groove-shaped recess 20 of the base 10 so that the surface (upper surface 10A) of the base 10 and the light emission surface 40A are substantially the same. It has become continuous. As a result, the light Z of the LED 32 reflected by the light reflecting surface 20C goes straight to the observer K via the light emitting surface 40A, so that the light emitting surface 40A becomes very bright illumination. The leg part 42 is continuously formed so as to protrude from a part of the light emitting surface 40A of the bar-like illumination part 40, and further guides the light transmitted through the bar-like illumination part 40 to the inside thereof.

  Here, the outer shape of the decoration portion 44 is decorated in the appearance of a horse and is continuously formed on the leg portion 42. Further, the decoration portion 44 is expanded on the longitudinal direction side of the bar-shaped illumination portion 40 as compared with the leg portion 42. That is, when the decorative plate 14 is viewed in plan, the leg portion 42 is constricted with respect to the decorative portion 44 and the rod-shaped illumination portion 40. Thereby, the decoration function by the edge 45, such as an outline, is obtained in the decoration part 44, and the illumination function by the light emitting surface 40A can be obtained in the rod-shaped illumination part 44, respectively. Since the decoration part 44 is held by the bar-shaped illumination part 40 via the leg part 42, the light that has passed through the inside of the bar-shaped illumination part 40 and the leg part 42 is guided into the decoration part 40. Accordingly, since the light passing through the inside is emitted from the end edge 45 of the decorative portion 44, the contour is raised by the light. Further, the edge 45 is also illuminated by the illumination light S emitted from the light emission surface 40A of the rod-like illumination unit 40. Therefore, the edge 45 of the decoration part 44 is further emphasized by the irradiation of the light S from the outside and the light emission of itself. Moreover, the rod-shaped illumination part 40 is detachable with respect to the groove-shaped recessed part 20, and can replace | exchange the decoration board 14 whole freely now.

  According to the light decoration device 1 of the present embodiment, the bar-shaped illumination unit 40 functions as illumination by emitting light from the LED light source unit 12. In particular, the presence of the light reflecting surface 20 </ b> C disposed in the groove-like recess 20 causes the light of the LED 32 to go directly to the observer, so that the observer can be noticed. On the other hand, the decorative portion 44 whose appearance and the like are devised is illuminated by the light S that travels in the same plane as the edge 45 while the edge 45 emits light by light passing through the interior. Can be raised.

  Moreover, according to this optical decoration device 1, since the decoration board 14 is comprised so that attachment or detachment is possible using the groove-shaped recessed part 20, the decoration board 14 decorated variously can be replaced | exchanged easily.
