Description

  The present invention is an illuminating device, and more particularly, an illuminating device having an information display function, and can freely select to project display information on the apparatus itself or the outside of the apparatus, and creates an environment with a unique atmosphere as a mood lamp. The present invention relates to a lighting device having a function.

  Conventionally, a rotating lantern is known as a lighting device having a function as a mood lamp. This rotating lantern is arranged so that the lantern inside the lantern made inside and outside rotates, and a cutout is pasted on the inner surface of this lantern, and the cutout illuminated by the lighting arranged inside It is projected on the outside lantern. However, since what is displayed on the outside lantern is a shadow picture that is interesting, a new decoration device has been proposed (for example, Patent Document 1).

This decoration device has an opening in the peripheral wall surface of the device body, and you can sequentially see the pictures displayed on the peripheral surface of the rotating body arranged inside, and the scene is as if you were looking at the room from the outside. In addition, a fantastic decoration device is realized by illuminating the rotating body with a lamp from the inside.
JP 11-195304 A

  The problem to be solved by the present invention is that the decoration device described above can only be seen from the outside of the device, and only the pattern displayed around the rotating body. Changing the pattern can also enlarge the pattern. It was impossible to see, and the size of the pattern and the environment for viewing the pattern were limited.

  The present invention solves the above problems and has a function as a mood lamp capable of freely selecting whether to display information to be displayed on the apparatus itself or to project it to the outside such as a screen for a large display. It is an object to provide a lighting device.

In order to solve the above-mentioned problems, the lighting device according to the present invention has the following requirements.
(A) At least a part of the apparatus main body is constituted by a translucent panel, and the irradiation light from the light source disposed inside the apparatus main body is transmitted through the liquid crystal display to project display information on the inner surface of the panel. The display information can be viewed from the outer surface of the panel. (B) A reflecting mirror is arranged between the liquid crystal display and the panel, and the irradiation light transmitted through the liquid crystal display is reflected by the reflecting mirror. Projected on the back side of the panel and brightly illuminated the entire panel

  The reflecting mirror is attached to the inner side surface of the opening / closing lid provided in the apparatus main body, and when the opening / closing lid is closed, the irradiation light transmitted through the liquid crystal display is reflected by the reflecting mirror and applied to the inner side surface of the panel. When the display information is projected and the opening / closing lid is opened, the irradiation light transmitted through the liquid crystal display directly projects the display information onto a projection surface such as a wall so that the projection method can be freely selected by the opening / closing lid. Good.

  According to the first aspect of the present invention, since the light transmitted through the liquid crystal display is not directly projected onto the panel but is once reflected by the reflecting mirror and projected onto the panel, the distance from the light source to the panel can be increased. The display information projected on the panel can be greatly projected while downsizing the apparatus.

  In addition, since the image is inverted by being reflected by the reflecting mirror and projected onto the back side surface of the panel, the information displayed on the liquid crystal display can be correctly viewed from the front side of the panel.

  According to the invention of claim 2, it is possible to freely select whether to display the display information on the apparatus itself or to project it onto a projection surface such as a wall by a simple operation of closing or opening the opening / closing lid.

  Moreover, when viewed from the front side of the panel, it can be inverted by a reflecting mirror and projected to the back side of the panel, and when projected on a projection surface such as a wall, it can be projected directly without being inverted, so the display screen of the liquid crystal display can be Two projection methods can be freely selected without requiring an operation or a program of whether or not to invert depending on the projection method.

  FIG. 1A is a front perspective view showing an example of an illuminating device according to the present invention. The illuminating device A includes a device body 1 formed in a spherical shape on a base 2 freely in front, rear, left, and right. It is placed so that it can be rotated. A panel 3 formed in a substantially hemispherical shape with a translucent white resin is arranged on the front surface of the upper device main body 1, and display information projected from the inside can be seen through the panel 3 from the front side of the panel 3. It is like that. Furthermore, an opening / closing lid 4 can be opened rearward with the hinge 5 as a fulcrum on the back side of the apparatus main body 1 (see FIG. 1B).

  As shown in FIG. 2, a projection device 10 and a reflecting mirror 11 including a light source body (LED) 6, a condensing lens 7, a liquid crystal display 8, and a projection lens 9 are disposed inside the apparatus main body 1. The light of the body 6 is transmitted through the liquid crystal display 8, reflected by the reflecting mirror 11, and the display information displayed on the liquid crystal display 8 is reversed to the back side of the panel 3 as shown in FIG. Projected.

  The display information that is inverted and projected onto the panel 3 as described above is displayed as the correct display information a when the panel 3 is viewed from the outside of the apparatus (see FIG. 4). Even if there is, it can be read correctly. In addition, since the panel 3 is a translucent resin, the irradiation light applied to the panel illuminates the entire panel 3, so that it can also function as a mood lamp.

  On the other hand, as shown in FIG. 5A, when the opening / closing lid 4 is opened, the upper surface of the projection device 10 appears from the opening 12, so that the light transmitted through the liquid crystal display 8 is as shown in FIG. Without being reflected by the reflecting mirror 11, the light is directly irradiated from the opening 12 to the outside of the apparatus, and the display information a is projected onto a wall or the like. Therefore, not only a function as a mood lamp but also a function as a projector can be exhibited. Yes (see FIG. 6). Since the display information at this time is not reflected by the reflecting mirror 11, it is projected onto the projection surface without being inverted, so that the user can correctly read even the display information composed of characters.

  As described above, the display information displayed on the liquid crystal display 8 is inverted by the reflecting mirror 11 when viewed from the front side of the panel 3 and projected on the back side of the panel 3, and inverted when projected on the projection surface such as a wall. Whether the display information is viewed indirectly or not depending on whether the door 4 is simply opened or closed, without requiring an operation or program to turn the display of the liquid crystal display 8 upside down. Alternatively, various selections such as whether to view individually or multiple times can be easily made.

  In addition, when the projection device 10 is installed and display information is irradiated on the panel 3, the distance from the light source to the panel 3 can be increased by reflecting the transmitted light transmitted through the liquid crystal display by the reflecting mirror 11. As shown in FIG. 3 (a), the outer diameter L1 of the apparatus can be made shorter than the outer diameter L2 of the apparatus when the panel is directly irradiated without using the reflecting mirror 11 (see FIG. 3 (b)). ), The display information projected onto the panel 3 can be enlarged and displayed while reducing the size of the projection device 10.
