An embodiment of the present invention will be described in detail with reference to the drawings.
The present invention basically includes a shaped body A facing the front surface, an illuminating body B provided on the back thereof and irradiating the back, and a rear projection for projecting light from the illuminating body B disposed behind the illuminating body B. In combination with the plate C, if necessary, the background model D is integrally formed on the back of the model A facing the front.

  1 to 4 are a front view, a side view, a rear view, and a cross-sectional explanatory view showing a configuration of a main embodiment of the present invention.

  The present invention has a configuration in which a shaped body A, an illuminating body B, and a rear projection plate C are used.

The shaped body A is basically composed of a standing image and a sitting image that embody religious or spiritual thought.
The model A facing the front is, for example, a statue of Mary (see, for example, FIGS. 1 to 4), a statue of Buddha (for example, see FIGS. 29 and 30), or a statue of Christ or a goddess. It is not limited to these, but may be an animal or a building related to religious spiritual thought, such as a crane, a dragon, a giraffe, a typical Western church, a cross, a crown, or the like.
The model A is modeled with ceramics, porcelain, synthetic resin, metal, glass, etc., and the material is not limited.

Moreover, the inside is formed hollow as necessary, or is formed into an internally filled mass.
This structure can be variously selected depending on the structure in which the illuminating body B described below is mounted on the back.
Below, the structure which formed the modeling body A hollow, opened the back, and provided the cover body G in the opening part so that attachment or detachment is possible is demonstrated.

In the hollow portion of the shaped body A, an illuminating body B for irradiating the back of the shaped body is accommodated.
The illuminating body B is composed of, for example, a filament type lamp, an LED, a micro projector, and the like.
As the illuminating body B, there are an embodiment of an illuminating device in which a filter having a light transmission hole formed later and a light source are integrated, or an embodiment in which a plurality of LEDs are incorporated in a hollow tube to form a light emitting tube.
The illuminating body B may have various structures such as a form housed in the hollow inside of the shaped body A and a form attached to the back surface of the internally filled shaped body A as described later.

A rear projection plate C is disposed behind the illuminating body B in order to project the irradiation light.
As the rear projection plate C, for example, a wall surface, a floor surface, a ceiling surface, or a screen board of a building is used.
For example, by using the rear projection plate C as a screen board, the irradiation light of the illuminating body B can be efficiently reflected as a reverse light beam on the modeling body A side.

  When the illuminating body B is turned on by the configuration composed of the shaped body A, the illuminating body B, and the rear projection plate C, the rear rear projection plate C is added to the shaped body A such as a Buddhist image or a Maria image with a religious color. The indirect light consisting of the reverse rays from the surface is irradiated and the contour of the shaped body A emerges from the backlight, creating a unique light atmosphere in the shape of the shaped body A. Furthermore, the shaped body A has a front surface of the shaped body A. The face shape itself can also give a religious and spiritual atmosphere more than a mere shaped shape by indirect light leaking from the reverse rays to the periphery of the shaped body.

  Further, as a structure for mounting the illuminating body B to the modeling body A, a form structure in which light is irradiated only to the rear of the modeling body A, or light irradiation should be applied to the rear side and the rear oblique direction of the modeling body using a light emitting tube. There may be a positional structure.

A specific structure for mounting the illuminating body B to the shaped body A will be described below.
As shown in FIGS. 1 to 4, the molded body A has a hollow interior, the illuminating body B is accommodated in the hollow interior of the rear opening, and a lid G can be freely mounted on the rear opening. The lid is closed.
A light transmitting hole 11 is formed in the lid G, and the light of the illumination body B is irradiated from the light transmitting hole 11.

  When the illuminating body B is turned on, the predetermined light transmitted through the light transmission hole 11 is irradiated to the rear projection plate C arranged behind the back of the model A, and a predetermined optical image by the light is projected on the rear projection plate C. This optical image is reflected forward from the rear projection plate C, recognized by the viewer as a reverse ray from behind the model A, illuminates the religious spiritual thought and religious shape of the model A from the back, Performs not only the beauty of body A but also the appearance of religious atmosphere and religious shadows.

That is, as shown in FIG. 5, the light L <b> 1 from the illuminating body B passes through the through hole 11 of the lid G attached to the back surface of the hollow shaped body A and is radiated to the screen board S. A light image composed of the through holes 11 is projected on the screen. Thereafter, the light L1 from the illuminating body B is reflected by the screen board S to become a reverse light L2, and the light of the backlight that has leaked forward without being interfered with the Maria image of the model A projects the expression of the Maria image of the model. It becomes like this.
Further, the reverse light L2 from the screen board S is interfered with the Maria image, and the front of the Maria image becomes a shadowed portion of the shadow of the reverse light, but becomes the non-interfering light around the Maria image in the reverse light shadow. The light L3 diffused on the outer periphery of the shaped body A, combined with the backlight shadow of the Maria image, allows the light L4 to lift the outline of the Maria image and create a solemn atmosphere of the Maria image with light. .

The shape of the light transmission hole 11 provided in the lid G can be configured in various shapes in consideration of the shape type of light projected on the rear projection plate C, the form of reflected light of the light, and the like.
For example, if the shape is such that a plurality of long holes are formed radially, the viewer can visually recognize the radial light image created by the plurality of long holes as the back light of the shaped object A, and the reflected light is shaped. It can be visually recognized by the viewer as a reverse ray from behind the body A, and the religious and spiritual significance of the shaped body A can be created in the shadow of light.

  The illuminating body B uses a normal light source lamp 17, but can further change the light emitted from the light transmission hole 11 by devising the filament shape of the lamp. In FIG. 4, reference numeral 17 a is a socket for the illumination lamp 17, 17 b is an electrical wiring, and 18 is a power supply for supplying electricity to the illumination lamp 17.

[Various shapes of light transmission holes]
In particular, by changing the shape of the light transmission hole 11 formed in the lid G in various ways, the shape of the light projected onto the rear projection plate C changes in various ways, and the religious spirit atmosphere of the shaped body A is further changed. be able to.

  For example, as described above, the light-transmitting holes 11 in FIG. 6 are formed in 12 long holes and arranged radially, so that a radial light image can be projected on the screen.

Moreover, as shown in FIG. 7, the illumination body accommodated in the hollow part of the molded object A can also be comprised with the box-shaped filter F1.
In other words, the box-shaped filter main body F1 containing the illumination lamp 17 is housed in the hollow portion of the shaped body A, the front opening F2 is provided in the filter main body F1, and a light image is formed in the front opening F2. A filter F is provided, and the design filter F is formed with a light transmission hole 11 composed of a circular hole and a plurality of radial holes.
Moreover, the illumination body accommodated in the hollow part of a modeling body can also be comprised with a micro projector.

That is, when the design filter F in which the light transmission hole 11 is formed is replaced, various changes in image light can be enjoyed on the screen depending on the type of the light transmission hole 11.
Furthermore, when a lens mechanism L is formed in which a lid opening G1 is formed in a part of the lid G, and the lens mechanism L can be freely expanded and contracted, the illumination lamp 17 and the rear projection inside the modeling body A are operated by operating the lens mechanism L. The image forming distance with the plate C can be adjusted, and even when the distance to the rear projection plate C is short, the image from the light transmission hole 11 can be clearly displayed.
Note that the box-shaped filter body F1 may be provided continuously on the back surface of the shaped body A without being stored in the hollow portion of the shaped body A.

Further, the illuminating body B has a configuration in which a reflecting mirror 19 is disposed behind the illumination lamp 17 as shown in FIG. 8, and the amount of light emitted from the light transmission hole 11 can be increased by the reflecting mirror 19. The amount of the reverse ray from the screen S also increases, and the light of the backlight that has leaked forward without being interfered with the Maria image of the modeling object A further reflects the expression of the Maria image of the modeling object.
Further, the reverse ray L2 from the screen board S is interfered with the Maria image, and the front of the Maria image becomes a shaded portion of the shadow of the reverse ray. The light L3 diffused at the outer periphery of the background shaped body D in this way, combined with the back light shadow of the Maria image, raises the outline of the Maria image, creating a solemn atmosphere of the Maria image. It can be brewed.

Further, as shown in FIG. 8, an illumination lamp 17 of the illuminating body B is provided in the modeling body A so as to be movable up and down along the wall surface inside the modeling body A.
That is, a rail 20 that allows the illumination lamp 17 to move is laid on the inner wall surface of the shaped body A, and a socket 17a is vertically movable along the rail 20.

  When the illuminating body B moves in the vertical direction along the rail 20, the direction and the amount of light emitted from each light transmission hole 11 change, and the amount of light diffused outward of the background shaped body D changes in the vertical direction. It will be. Therefore, the light image projected on the rear projection plate C is brightened and darkened in the vertical direction, and the religious atmosphere of the shaped body A can be further presented to the viewer in the backlit atmosphere with respect to the shaped body A.

Note that a front and rear rail mechanism that is movable in the front-rear direction as well as the vertical direction may be provided in the hollow portion of the shaped body A.
In this way, by providing the front and rear rail mechanism that enables the illuminating body B to move in the front-rear direction, the amount of light diffused outward of the background shaped body D can be changed in the front-rear direction. The brightness of the image projected on the projection plate C can be adjusted.

The light emitting tube 80 can be provided on the back surface of the modeling object A instead of the illumination lamp 17 of the illuminating object without accommodating the illuminating object B in the hollow modeling object A.
That is, it can be mounted on the surface of the lid G of the hollow shaped body A or attached to the back surface of the internally filled shaped body A.
Specifically, as shown in FIGS. 9 to 15, an annular groove D <b> 1 is formed on the back surface of the internally filled or hollow shaped body A, and the luminous tube 80 is embedded in the groove D <b> 1. The light emitting tube 80 is configured by incorporating LED chips 82a in a transparent or translucent hollow tube body 81 at regular intervals.

  In the hollow portion of the tube body 81, an LED light source lamp 82 (see FIG. 15) in which an LED chip 82a mounted on a heat dissipation board 82b is electrically connected, and side radiation refractors 83a and 83b having a large light refractive index are provided. And built-in.

  As shown in FIG. 15, an LED illumination lamp 82 in which a plurality of LED chips 82a are connected via internal wirings 84a and 84b is connected to a driving power supply unit 85. In addition, a main body control unit 86 is connected to the power supply unit 85 in order to control dimming and lighting intervals of LEDs based on signals from the external controller 90. In the figure, 81a is the inner wall of the tube body 81, and 81b is a wiring hole. 84c and 84d are wiring, 84e and 84f are electrical connectors, 91 is a slave unit control unit, 86a is a communication unit, 91a is a child chip, and 92 is a battery.

  Furthermore, an air supply hole 81c and an air discharge hole 81d for supplying and discharging air for cooling the inside of the tube body 81 are formed in the left and right middle lower portions of the tube body 81 in the longitudinal direction.

  On the inner wall of the tube body 81, substantially triangular side-surface refracting bodies 83a and 83b are formed in the longitudinal direction on both walls excluding the inner wall portion in the vertical direction from the light emitting surface of the LED chip 82a. The side radiation refractors 83a and 83b are formed by dividing a substantially circular arc in cross section with a large refractive index of light into three parts.

  The luminous tube 80 can be turned on / off, dimmed, changed in color, and the like by an external controller 90.

  In order to air-cool the LED light source lamp 82, the air supply part 88 provided in the shaped body A has an air supply hole 81c at the bottom of the tube body 81 and an air discharge via a supply air pipe 87a and a discharge air pipe 87b. The holes 81d are communicated with each other, and air is circulated in the tube body 81 so as to cool the air. In FIG. 12A, reference numerals 11c and 11d denote an air discharge hole and an air supply hole formed at the bottom of the annular groove D1, and the end of the discharge air pipe 87b and the supply air pipe 87a The ends are connected in communication. Reference numeral 11b denotes a wiring hole formed in the bottom of the annular groove D1, and communicates the external wiring 84c and 84d of the LED light source lamp 82. 84e and 84f are connectors for connecting the external wirings 84c and 84d and the power supply unit 85.

The tube body 81 is embedded so as to project a half of the peripheral surface from the annular groove D1, and a side radiation refractor having a large light refractive index in the hollow inner wall of the tube body 81, particularly in the interior corresponding to the outer half peripheral surface. 83a and 83b are incorporated. Therefore, when the LED chip 82a is turned on, a part of the emitted light is incident on the side radiation refracting bodies 83a and 83b, refracted greatly, and the light transmitted through the protruding tube body 81 is incident on the surface of the modeling body A. Therefore, the emitted diffused light adds a shadow to the modeled body and gives a viewer a fantastic impression.
Since the above-described luminous tube 80 can be deformed by utilizing the characteristics of the tube, the luminous tube 80 can be freely deformed, for example, to form a light irradiation to the rear projection plate C on the rear surface of the Maria image of the shaped body A. It is possible to bend and install in a shape that can be freely changed.
Moreover, it is also possible to attach the light emitting tube 80 to the trunk | drum, the leg part, and the neck part of the modeling body A as a surrounding state as needed. In this way, the light emitting tube 80 is three-dimensionally deformed other than simply mounting the light emitting tube 80 on the back surface of the modeling object A, so that the light irradiation to the modeling object A is directly three-dimensional as well as the reverse rays from the rear projection plate C. By irradiating light from the light emitting tube 80, it is possible to further increase the religious spiritual significance of the shaped body A.

  The material of the tube body may be a translucent material other than transparent.

Scaled V-shaped large and small projected images 61 and 62 are projected as images that are alternately arranged on the virtual circle C, and are projected on the back and surrounding projection planes of the model A. In FIG. 22 and FIG. 23, 8d is a girdle part.

  As shown in FIG. 26, when the lower half of the glass particle 8 is buried in a position close to the light transmission hole 22 of the background model D, for example, a position separated by about 3 mm, the light from the light source is transmitted through the light transmission hole. 22 is incident on a part of the cut surface of the crown portion 8c of the glass particle 8 and diffusely reflected, and is emitted from the table 8f to emit a weak shine.

  Moreover, as shown in FIG. 27, the modeling object A and the substantially semicircular background modeling object D are good also as a detachable structure. When assembling the background shaped body D integrally with the back surface of the shaped body A, a close contact structure is adopted in which the light of the illuminating body B does not leak from the fitting surface.

  Thus, by making the background modeling body D detachable, it is possible to change various light images projected on the screen by exchanging, and it is possible to produce light that suits the taste of the viewer.

  Furthermore, by forming a light-transmitting hole having a predetermined shape on the entire circumference of the background shaped body D, various lights diverge from the side of the outer peripheral surface of the shaped body to the surroundings, and not only the rear but also the rear projection plate. Light projection can be performed on a side wall surface or the like standing upright at an angle. For example, a peacock-shaped light pattern or a flower-shaped light pattern is projected on a wall, etc., and a beautiful light projection space can be formed in the entire space around the model body along with the change of light around the model body. There is an effect that can be done.

  In addition, the rear projection plate is not only arranged in a plane behind the modeled body, but also has a substantially U-shape in plan view or a mountain shape in plan view as shown in FIG. The image can be projected on the rear projection plate C to enjoy the change in the image of the entire space.

When the light emitting tube 80 is mounted on the surface of the background shaped body D in this way, a light emitting device in which an annular groove D1 is formed on the back surface of the background shaped body D, and LED chips are embedded in the hollow tube body at regular intervals. The tube 80 is embedded.
At the groove bottom portion of the annular groove portion D1, heat radiating through holes 11a and the like communicating with the exhaust heat space formed in the background shaped body D are formed at predetermined intervals so as to radiate the radiant heat of the light emitting tube 80. doing.

The back-lighting device of this model is equipped with a robot function such as a hand, arm, head, and upper body, and a moving function, a bidirectional conversation function, and a facial expression function that changes to various expressions according to the environment and conversation. It may be a configuration.
The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.
