  As described above, there is an increasing demand for balloon-type lighting devices for various applications. In particular, the wide illumination range makes it suitable for lighting in emergency evacuation areas and event venues, and more effective uses are expected in places where many people gather. When a balloon-type lighting device is installed in a place where many people gather, the balloon-type lighting device that emits light will be noticed by many people. Therefore, when various information is transmitted from this balloon type illumination device, it becomes possible to quickly transmit information to many people. However, there is a problem in that effective information cannot be transmitted simply by adding characters or patterns to the body of the balloon as in the prior art, and the light emitted from the balloon is blocked by the characters or patterns. As a result, there is a problem of reducing the inherent high illumination function.

  This invention makes it an example of a subject to cope with such a problem. An object of the present invention is to provide an effective information transmission function without reducing the illumination function in a balloon-type illumination device or a balloon-type projector.

In order to achieve such an object, the present invention includes the following configurations among several inventions described in the specification.

(A), (b) is explanatory drawing which showed the light projector (balloon type light projector) provided with the balloon type illuminating device which concerns on embodiment of this invention.

  A balloon-type illumination device according to an embodiment of the present invention includes a balloon having a balloon outer skin, a blower for inflating the balloon, and a light source, and illuminates the surroundings with light emitted from the light source to the outside through the balloon outer skin. As one of the light sources, a projector for irradiating the inner surface of the balloon skin with projection light is provided. One or a plurality of projectors are installed inside or outside the balloon, and this is driven by a signal from the outside to project an image on the inner surface of the balloon outer shell so that the balloon outer shell functions as a transmission screen. Yes.

  A balloon-type illumination device according to an embodiment of the present invention having such a feature provides a balloon-type illumination device that allows many people to view images from outside the balloon and has an effective information transmission function. Can do.

  Conventional balloon-type lighting devices have a function that allows simple information display by sticking a balloon envelope itself or a sheet on which characters or images are written on the outside of the balloon. In the indication of car guidance and emergency use, it was possible to clearly indicate the location of a rescue center and the location of a refuge. On the other hand, in recent years, balloon-type lighting devices are increasingly used especially at event venues and emergency shelters, and people who are evacuated when using emergency shelters. Therefore, there is a demand for a function for transmitting various information and a function for providing entertainment.

  The balloon-type lighting device according to the embodiment of the present invention has a balloon-type lighting device having an information transmission function by causing the balloon outer shell to function as a transmissive screen of the projector, and can be used for evacuation in event venues and emergency situations. By using it in places, etc., it is possible to transmit a variety of information to many people and provide entertainment by video. In particular, by installing a projector with a built-in speaker, it is possible to enjoy television broadcasting as it is. In addition, by providing an information transmission function to a very conspicuous balloon-type lighting device, information can be effectively transmitted to many people.

  As one embodiment of the present invention, at least one projector having a relatively short projection distance is installed in a balloon and an image is projected onto the inner surface of the balloon outer skin. However, a plurality of projectors (for example, 2 to 4) are used. By installing it, it becomes possible to view images from any position outside the balloon, and to transmit information to more people. Also, by installing a plurality of projectors, it is possible to display various information at the same time and transmit various information.

  Since the projector basically looks at the reflected image that is projected onto the flat screen, it is designed so that the reflected image on the flat screen has no image distortion and the brightness of the entire screen is uniform. ing. If this is projected directly to the inside of the balloon and viewed from the outside of the balloon, the image will be reversed left and right, will be distorted, and will have a non-uniform brightness. In order to correct this, the video signal sent to the projector is corrected according to the shape of the inner surface of the balloon skin and is also corrected for projection onto the transmission screen.

  In order to improve color reproduction, the projector's light source often uses a halogen lamp with a relatively uniform wavelength distribution of visible light. It is desirable to do. For this reason, in the balloon illumination device according to the embodiment of the present invention, a white LED may be used instead of the halogen lamp as a projection light source in the projector. By using the white LED, the color reproducibility of the projected image from the projector is reduced as compared with the case of using the halogen lamp, but the power consumption can be greatly reduced. Suppression of power consumption is an important factor in an emergency, and for example, the number of balloon-type lighting devices and projectors that can be used with one generator can be increased.

  Moreover, since the balloon outer shell has a waterproof property, the balloon-type lighting device according to the embodiment of the present invention can exhibit an information transmission function even outdoors in rainy weather. Thereby, for example, information can be transmitted not only to lighting but also to many people even outdoors in an emergency evacuation area.
