JP 2004-071350 A

  However, although the above-described conventional lighting fixture with a display screen has a function as an information transmission means, if you try to impress an image to a viewer, a moving image gives a stronger impression than a still image. It is obvious. In general, the image displayed on the globe is a still image, not a moving image.

  Furthermore, even if the conventional lighting fixture with a display screen is a still image, for example, the illumination is turned off and the light source is cut off at the same time, and the surroundings become completely dark and nothing can be seen. This also does not function as a display device at all.

  The present invention has been made to solve the above-described problems, and after turning off the lighting, it is possible to provide a video display function such as a moving image to a lighting fixture that has not been used for anything until now. To. This aims to enable effective use of the space inside and outside the globe, which has not been utilized so far.

  The present invention is a lighting fixture provided with a light emitter, comprising: a translucent translucent glove that covers the outside of the lighting fixture main body; and an image projection mechanism that is installed inside the lighting fixture. The projection mechanism has an image display function of projecting an image on the inner surface of the translucent glove after the light emitter is turned off.

  Further, the image projection mechanism according to the present invention is a projector, the image projection mechanism is composed of an object to be projected, a lens, a reflection mirror, and a light source, and the light source of the image projection mechanism is the beans. It is characterized in that a sphere is used and a part of the translucent globe surface is constituted by a liquid crystal panel.

  Further, the present invention is a lighting fixture comprising a light emitter, comprising a translucent translucent glove that covers the outside of the lighting fixture body, and an image projection mechanism installed outside the lighting fixture, The image projecting mechanism has an image display function of projecting an image on the outer surface of the translucent glove after the light emitter is turned off.

  The image projected onto the translucent globe according to the present invention is a moving image or a still image.

  According to the lighting apparatus of the present invention, it has become possible to display images such as a TV by providing an image display function to a lighting apparatus that has not been used for anything after the lighting has been turned off. . As a result, the space inside the globe that could not be used up to now can be used effectively.

  Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the lighting fixture of the present invention.

  2. Description of the Related Art Conventionally, a film winding type projection display device has been put into practical use in place of a fixed type transparent plate on which graphics or the like are printed. This device is simple and has the effect of attracting the viewer's attention in terms of the movement of figures and the like in one direction, but it is not a so-called moving image, only a still image is moving. Therefore, the function as a display device is limited. The present invention intends to project a moving image on a glove by using a turn-off time of a lighting fixture by combining a projection mechanism such as an image projection device and the lighting fixture.

  First, as shown in FIG. 1, the lighting fixture according to the present invention uses a generally used structure as it is. That is, it comprises an instrument body 1 that is directly attached to the ceiling or wall, an annular fluorescent lamp 2 (hereinafter simply referred to as a fluorescent lamp 2), and a globe 3. A reflector 4 is attached to the instrument body 1, a lighting device (not shown) is incorporated inside the reflector 4, and a fixture 5 for fitting the fluorescent lamp 2 is provided outside. The fluorescent lamp may be a straight tube fluorescent lamp.

  Furthermore, a glove 3 that covers the entire outside of the instrument body 1 including the fluorescent lamp 2 is attached to the instrument body 1. The globe 3 is a spherical cover made of a translucent and translucent resin material. And it has the pull switch 7 which turns on and off the fluorescent lamp 2 and the bean bulb 6.

  A feature of the lighting fixture of the present invention using such a directly-mounted lighting fixture having a conventional structure is that an image projection device is installed inside or outside the globe. A glove is used as a screen, and a moving image (or a still image) can be projected and displayed on the inner surface or the outer surface.

  And normally, it uses as a lighting fixture, and pulls a pull switch at the time of light extinction, and turns off illumination. As soon as the power switch is turned off, the power switch of the image projection apparatus (for example, a liquid crystal projector) linked to the pull switch is turned on, and the image projection apparatus starts to operate. In other words, the power is switched to the image projection device at the same time when the illumination is turned off and the surroundings are darkened. And the image projected on the glove which has a screen function is projected. By making it possible to view this image from the outside of the globe, it is possible to provide a lighting apparatus having a screen display function in addition to the function as a lighting apparatus.

  Below, one Embodiment of the lighting fixture of this invention is described based on an Example. In the description of the first embodiment, FIG. 1 is used as it is.

  First, as shown in FIG. 1, the luminaire shown in the first embodiment incorporates a small projector 8 as an image projection device inside the reflector 4. As this small projector 8, for example, a key holder type projector using a light source such as an LED is commercially available, and its outer shape is sufficiently large to fit within a lighting fixture. In the present embodiment, a small projector 8 to which this existing projector is applied is built in the instrument body 1.

  FIG. 1 shows a state in which the projection lens 9 of the small projector 8 protrudes outward from the reflecting plate 4 and faces the globe 3 that is a screen. The projection lens 9 uses a projection lens whose focal length is set so that the projection image can be projected almost at the center position of the globe 3. In this case, the image projection apparatus only needs to include at least a projection light source, a reflection mirror, a projection lens, and the like. That is, it is only necessary that the individual projection means be arranged in a configuration that can function as a projector in the lighting fixture, and it is not always necessary to adopt a case structure that is compactly integrated as a projector device.

  Normally, the power source of the small projector 8 is set to OFF, and after the illumination is turned OFF, it is switched ON. The light emitted from the projection lens 9 is projected onto the inner surface of the globe 3 to form an image. At that time, it is preferable that the light emitted from the projection lens 9 can be directly projected substantially perpendicularly to the center of the globe 3. However, there is a case where the projection lens cannot be arranged at the center position of the instrument body due to space. In such a case, the center position may be shifted as shown in FIG. 1 and projected from an oblique direction, or the projection optical path may be moved to the vicinity of the center of the globe via a reflection mirror (not shown). Good.

  In the first embodiment, the small projector 8 is attached to the inside of the reflecting plate 4. However, the small projector 8 may be installed outside the reflecting plate 4, that is, in a space surrounded by the globe 3 and the reflecting plate 4. In this case, there is an advantage that optical path adjustment by a reflecting mirror or the like can be easily performed.

  In the lighting fixture configured as in the first embodiment, instead of using a small projector, a projection object 16 as shown in FIG. 2 may be installed inside the lighting fixture. The optical path from the light source 14 provided separately is enlarged by the two reflecting mirrors 15 and the projection lens 9, and the image of the projection object 16 is projected on the inner surface of the globe 3. FIG. 6 is a diagram showing projection examples 1 and 2 when the projection object is a watch. FIG. 6A is a diagram showing a dial image screen 10 of the analog display timepiece, where the dial is composed of a translucent plate and the letters and hands are composed of a non-translucent material. FIG. 6B is a diagram showing the time video screen 11 of the digital display clock. If the display portion is made of a light emitter such as an LED, a light source need not be used. Thereby, the time change of the clock can be projected and displayed as a moving image on the inner surface of the globe.

  Next, Example 3 will be described. In the second embodiment, a light source for image display is separately provided. However, in this embodiment, the bean bulb 6 (nightlight) of the lighting fixture is used as it is as the light source as shown in FIG. As a result, the projection mechanism is simplified, and the fluorescent lamp 2 of the lighting fixture is turned off, and at the same time, only the bean ball 6 is switched, and no special power supply device or the like is required. The optical path from the bean bulb 6 to the globe 3 is the same as that shown in FIG. However, in order to prevent the light from the bean bulb 6 from being scattered, the light bulb 18 is covered with a light shielding body 18. As for the brightness of the image, it is sufficient if a display function capable of reading the display screen in the dark is obtained.

  Next, Example 4 will be described. The lighting fixtures of Examples 1, 2, and 3 were configured to project an image on the inner surface of the globe. In this embodiment, as shown in FIG. 4, a projector 12 is installed outside and below the lighting fixture, and an image is projected from the lower side of the globe 3 onto the outer surface of the globe 3. That is, a separately installed illumination remote controller with a timer function or the like is installed outside the luminaire. In response to the signal from the timer remote controller 17, for example, the projector 12 is turned on at the same time as the illumination is turned off, and an image is projected onto the outer surface of the globe 3. In this way, the ON and OFF timings can be arbitrarily set by setting the time in the timer. Note that the projector 12 used here is not necessarily a small projector.

  Next, Example 5 will be described. In the present embodiment, as shown in FIG. 5, the central portion of the globe 3 that is usually formed of a translucent resin material is configured by a liquid crystal panel 13. Thereby, when using as a lighting fixture, a fluorescent lamp is used as a backlight, and white light is output from the liquid crystal panel 13. In addition, when used as a liquid crystal display monitor after the light is turned off, a video projector, an antenna, a TV tuner, or the like is connected to the lighting fixture. As a result, as shown in the projected image in FIG. 5, relaxation images, movies, TV images, and the like can be directly broadcast on the liquid crystal panel 13 provided on the globe 3.

  According to the lighting apparatus of the present invention, it is possible to give an advertisement effect and an aesthetic effect to a person who watches an image that appears on the globe after the light is turned off. Also, in places where many people gather, such as in station premises and underground malls, the utility value is great not only as a simple lighting device but also as an information transmission means.
