JP3148833U - Indirect lighting device that emits a projected kaleidoscope image - Google Patents

Abstract

In response to the emergence of a new projection kaleidoscope, taking advantage of the possibilities of the projection kaleidoscope, and capturing the luminous flux produced by it and the overall image of the image, it indirectly emits beautiful light using the projected kaleidoscope image A lighting device was devised. SOLUTION: A projection kaleidoscope is incorporated in a wall-mounted lighting box, and a part of or all of the surface in contact with the wall of the lighting box is transparent or open so that the kaleidoscope light is not obstructed. A kaleidoscope image indirect lighting device that displays kaleidoscope image of wall and ceiling, wall and floor or wall and wall at the same time.

Description

      The present invention relates to an indirect lighting device using a projection kaleidoscope.

  A kaleidoscope is an object in which objects with various shapes and colors, which are observation objects, are viewed through a lens barrel that is combined with a plane mirror, and the objects are created by multiple reflections on the mirror system in the lens barrel. In this way, you can appreciate delicate and elegant images. Since conventional kaleidoscopes are large enough to be viewed with one eye, there are many cases where the lens barrel is small and only one person can see and appreciate at a time. The maximum number of people who can appreciate a special kaleidoscope at the same time is about 2 to 3 people.

  It is significant to remove this restriction and allow people to watch at the same time and share a common impression. Therefore, a projection kaleidoscope has been invented that can project a bright kaleidoscope image generated by illuminating an object with a strong light source and an objective lens to be projected onto an external screen or object surface (see Patent Document 1).

Japanese Patent Application No. 2007-285546 Projection Kaleidoscope

Ordinary indirect lighting devices usually use a single color lamp or a color lamp using a filter as the light source. Therefore, in response to the emergence of a new projection kaleidoscope, the projection kaleidoscope was created by taking advantage of the possibilities of the projection kaleidoscope and grasping the emitted light beam and the overall image produced by it. Realization of an indirect lighting device that emits a variety of beautiful lights using video was required.

  A kaleidoscope with various color combinations as a structure in which a projection kaleidoscope is installed in a wall-mounted lighting box and part or all of the surface in contact with the wall of the lighting box is transparent or open so as not to interfere with the kaleidoscope light We have devised an indirect lighting device that emits kaleidoscope images, which is characterized by projecting kaleidoscope images on walls and ceilings, walls and floors, and walls and walls simultaneously.

  In addition, with the Kaleidoscope indirect lighting device of the present invention, an object that contains a transparent colored glass piece or plastic piece that forms a colorful kaleidoscope image is automatically rotated by a motor or the like, and the image projected on the ceiling, wall, or floor is displayed. It is an effective means to entertain people who are looking for beautiful changes automatically.

  When viewing a kaleidoscope image, it is possible to further impress the person who sees the object by changing the rotation speed of the object of the kaleidoscope in response to a change in the tempo of music being played around.

  With the present invention, a new projection kaleidoscope system has realized an indirect lighting device with a new and varied kaleidoscope image. In addition, an indirect lighting device that projects kaleidoscope images, such as the ceiling, floor, and walls, at the same time that gives viewers even greater excitement by changing the speed of the kaleidoscope image changes according to the surrounding music and sound. It was realized.

The optical axis of the light beam emitted from the projection kaleidoscope is arranged so as to be substantially parallel to the screen surface. In other words, in a system that illuminates a wall surface or screen from a tangential direction, a cut surface close to the optical axis of each object beam appears on the screen, and a linear or ribbon-like elongated image corresponding to the color of the object appears. . Since it is difficult to plot the entire projected video created by the object video composed of the real image and the mirror image together with the system layout example, FIG. 1 shows an example of the video created by one object beam. FIG. 1A is a side view thereof, and FIG. 1B is a front view thereof. When the position of the object or the mutual positional relationship is changed, the position or interval of the object beam changes, so that various changes occur in the image. In practice, this image is high, and multiple reflections are repeated by the mirror, and the image on the screen becomes an image greatly expanded by the mirror multiple reflection. FIG. 2 shows an example of a multiple reflection image when an equilateral triangle mirror is used. In an arrangement in which the emitted light beam is projected at an angle close to the screen surface, an image close to a conventional kaleidoscope image can be viewed.

  A conventional kaleidoscope of a single object folded 90 degrees is added to the upper part of FIG. With the system that changes the screen angle, you can simultaneously view images close to linear images and images close to conventional kaleidoscope images.

That is, the example shown in FIGS. 1A and 1B is an example of a usage method in which a projection kaleidoscope is installed upward on a wall surface in a room and an image is projected onto the wall surface and the ceiling surface. In the usage method installed in the corner of the room, different images can be projected on the two wall surfaces and the ceiling surface.
When the example shown in FIGS. 1A and 1B is mounted upside down, a projected image appears on the wall and the floor simultaneously. Similarly, when the image is rotated 90 degrees, a projected image appears on the wall and the corner wall of the room at the same time.

  FIG. 3 shows a configuration diagram of a system in which the rotation of the kaleidoscope object changes in accordance with the surrounding music and sound tempo. With this system, people who are watching kaleidoscope images can be given more peace of mind.

With the present invention, in stores, concourses, and homes, it is now possible to enjoy the image by simply attaching a new concept of indirect lighting that produces colorful and changing kaleidoscope images.
