うな虞れないという利点を奏するものである。In order to solve such a problem, the applicant of the present application has installed a telescopic support column on a trolley carrying a generator.
We proposed a new floodlight in which a balloon-type lighting device having a bulb built in a balloon inflated by an air supply means is provided on the upper end of the telescopic support, and filed previously (Japanese Patent Application No. 2001).
-150911). The balloon-type floodlight of the prior application softens the glare by indirectly irradiating the light of a light bulb in the balloon to the outside through the balloon, and the floodlight is emitted to a driver of a passing vehicle in road construction or the like. It has an advantage that it does not become an obstacle.

がかかるという不具合が生じる。When the technical contents of the above-mentioned balloon type floodlight of the prior application are examined in more detail, there is room for improvement in the following points. In other words, this kind of balloon type floodlight is "under construction" on the peripheral surface of the balloon.
It may be possible to display the letters such as “Caution” by printing etc. to call attention to the driver of a passing vehicle.However, in the conventional balloon-type floodlight, the upper circular sheet material forming the upper half of the balloon is used. , The lower circular sheet material forming the lower half of the balloon is sewn together to form the balloon, so when the balloon is inflated, some wrinkles occur on the balloon peripheral surface, and the balloon peripheral surface is displayed. There is a risk that the characters will not be readable. In order to eliminate this, it may be possible to form a substantially globe-like shape composed of a plurality of divided sheet materials obtained by dividing the balloon peripheral surface in the meridian direction so that wrinkles do not occur. Since the sheet materials have to be sewn to each other, there is a problem that it takes time and cost to manufacture the balloon.

However, in the balloon type floodlight of the prior application, the upper and lower end portions of the frame body that surrounds the bulb and prevents contact between the balloon and the bulb, are formed by the upper and lower circular plates, respectively, to define the center portion of the upper surface and the center portion of the lower surface of the balloon. The sandwiched upper and lower circular plates are fixed to each other with bolts and nuts.
There was a problem that it took time to replace the balloon.

とになる。Further, in the balloon type floodlight of the prior application, the frame body is composed of a wire mesh frame body, and there is a problem in strength for long-term use and use under strong wind conditions. Furthermore, the balloon type floodlight of the prior application is configured as a dedicated device for a balloon type lighting fixture, in which a telescopic column is erected on a trolley carrying a generator, and the light from a light bulb is reflected on the upper end of the telescopic column. Owners of conventional floodlights equipped with a luminaire that projects light forward with a board must purchase a balloon-type floodlight separately, including a generator, a trolley, and two sets of telescopic columns. You will own it.
