Abstract

PROBLEM TO BE SOLVED: To widely light a circumference with lighting on the ground or easily change lighting color, by constituting a lighting system with a light projecting source for radiating light upward from the ground and a reflecting balloon floating in the air by providing a reflector connected to the ground reflecting light to the ground being isolated from the light projecting source. SOLUTION: A resin-sheet made radiating balloon 3 floats in the air by filling hydrogen and helium in it, is tethered to the ground 2 through several ropes 4, and a reflector 5 is provided on the radiation surface of a light projecting source 1. The reflector 5 is a flat plate made of metal material or non-metal material, or a bent plate machined in a spherical surface shape, and is mounted in fixing method or an angle adjusting method. The radiating balloon 3 floats adjusting the length of ropes 4 on the ground 2, then light projected upward from the light projecting source 1 on the ground 2 is reflected by the reflector 5, and other ground position isolated from the light projecting source 1 is lighted. A construction field or an outside event place and be lighted without troublesome work for assembling scaffolds or installing struts.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balloon device which is installed at a construction site, an outdoor playground, an outdoor event square, etc., and illuminates a wide area.

[0002]

2. Description of the Related Art Lighting devices conventionally used in dark construction sites, outdoor playgrounds where many people gather, outdoor event squares, and the like, hang a projection light source on a high pole or mount it on a wall of a surrounding building. It is lit and fixed.
Therefore, there is a problem that a troublesome work of assembling and fixing the lighting fixture must be performed every time the lighting square is moved to a new place. Lighting devices that solve these problems have been developed for some time. For example, Japanese Patent Application Laid-Open No. 57-74901
Japanese Patent Application Laid-Open No. 9-09-1991 discloses that a lamp connected with a power cord on the ground and a lighting device provided with a reflector around the lamp are fixed by wires and suspended below a floating balloon. Japanese Patent No. 306210 discloses a balloon lighting device in which a lighting device provided in a transparent balloon is mounted on a column holder provided with a power cable and a light bulb socket at a substantially central portion, and further Japanese Patent Application Laid-Open No. 10-188622. And "a lighting balloon configured by attaching an inflatable envelope balloon made of a thin flexible material and incorporating a lighting device having a light bulb to the upper end of a column".

[0003]

The above illuminating device is a balloon illuminator which illuminates a balloon provided with an illuminating device in a balloon or hangs it on a high support to illuminate the surrounding area widely. Device. However, since these are lighting devices for attaching a lighting device to a balloon, there is a problem that when the lighting device fails, the balloon must be dropped on the ground and repaired. If the balloon is installed at the tip of a pillar, a lighting device that builds a scaffold and builds a pillar every time a construction site or outdoor event moves to a new location, and lifts and fixes lighting equipment of considerable weight There was an annoying problem of repeating the work.

The present invention has solved these problems, and it is extremely easy to move and set up the equipment. In addition, the lighting of the entire area can be widely illuminated by lighting operation on the ground, and the color of the lighting may be changed depending on the content of the event. It is an object of the present invention to provide a balloon lighting device that can be easily changed.

[0005]

SUMMARY OF THE INVENTION The present invention has achieved the above-mentioned object, and the gist of the present invention is to provide a light source which emits light upward from the ground, and a ground light which is anchored on the ground and isolated from the light source. This is a balloon illuminating device including an irradiating balloon which floats in the air by providing a reflector for projecting light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. The drawings show an embodiment of the present invention, and FIG. 1 shows a side view of the present invention. In FIG. 1, reference numeral 1 denotes a projection light source. As the light source 1, a commonly used light bulb, a search light for illuminating a distant place, or the like is used. The light source 1 is installed on the ground 2 so as to emit light from the ground toward the heavens (upward). The projection light source 1 may be provided as a fixed type that emits light in only one direction, or a revolving type that can freely change the emission direction. Reference numeral 3 denotes an irradiation balloon. The irradiation balloon 3
A light balloon that floats in the air with hydrogen gas or helium gas filled inside with a resin sheet that is difficult to break. It is anchored by several ropes 4 from the ground 2 and provided with a reflector 5 on the irradiation surface of the projection light source 1. Have been. FIG. 2 shows a top view of a case where the irradiation balloon 3 is anchored to the ground 2 with four ropes 4. The reflector 5 transfers the light emitted from the projection light source 1 toward the ground 2 again, and is made of a highly reflective metal material, a non-metal material, or a material obtained by applying a reflective paint on the surface of a foldable fabric. A flat plate or a curved plate processed into a spherical surface, provided with a fixed type when a constant firing angle is always required or a manually or remotely controlled angle adjustment type when a different firing angle is required Is also good. FIG. 1 shows an example in which a curved reflector 5 processed into a spherical surface shape is fixedly attached to the projection surface of the irradiation balloon 3.

The balloon illuminating device of the present invention configured as described above floats the irradiation balloon 3 in the air while adjusting the length of several ropes 4 on the ground 2 and then projects the light source on the ground 2 The light projected upward from 1 is projected via a reflector 5 attached to the balloon 3 for irradiation, and another ground position isolated from the light source 1 is illuminated. Further, in the present invention, when the reflector 5 whose projection angle can be adjusted is used, the light source 1
It can be illuminated to another ground position far away from. Further, the projection light source 1 and the like can function sufficiently while being mounted on, for example, a vehicle or a movable object, and this mechanism is a balloon lighting device in which movement and installation are significantly facilitated.

[0008]

According to the balloon lighting device of the present invention as described above, there is no danger because there is no troublesome work such as assembling a scaffold and installing a support, and the construction site and the outdoor event square are immediately illuminated. Can do things. In addition, since the transfer can be performed by adjusting the length of the rope pulling the irradiation balloon floating in the air, there is no need for installation work in a new place. In addition, since the floodlight operation is performed on the ground, there is a feature that depending on the content of the event, the desired illumination color such as red or blue can be easily changed. Also, the range of illumination can be changed by changing the angle of the reflector. Further, the balloon lighting device of the present invention has a feature that, by being mounted on a vehicle or a movable object, it can easily illuminate a dark construction site or an outdoor event plaza which is easy to move.
