  In the illumination device according to the present invention configured as described above, the illumination support structure stably arranges the illumination lamp inside the membrane structure against the air pressure from the blower. In addition, the illuminating lamp disperses and transmits light from the inner side of the membrane structure bulged and retained by the blower toward the outer peripheral side, thereby enabling illumination in all directions with high brightness. Furthermore, the colored transparent film sheet stretched outside the protective net illuminates the membrane structure in various colors. In addition, the air discharge hole discharges the air sent into the membrane structure by a blower little by little, and maintains the air pressure in the membrane structure at a constant value at all times. Keep shape. In addition, the radiant heat generated by the light from the illuminating lamp is dissipated to the outside by the air of the blower, so that the heat is not trapped in the membrane structure.

  Since the present invention is configured as described above, it is possible to stably arrange the illuminating lamp inside the membrane structure against the air pressure from the blower, and it is higher in brightness and omnidirectional in the past. Lighting is possible.

The lighting device 1 is a heat-resistant sheet that is flexible and can disperse and transmit light. For example, the lighting support structure 3 is formed inside a bag-shaped film structure 2 formed of a canvas material or a parachute cloth material. For example, a metal halide lamp that is supported and arranged, and for maintaining the inside of the membrane structure 2 at a constant atmospheric pressure so that the membrane structure 2 is bulged and retained. The blower 5 is provided on the lower side in the illumination support structure 3. The illumination lamp 4 may be, for example, an incandescent lamp or a halogen lamp other than the metal halide lamp. By the way, as described above, the bag-like film structure 2 formed of a heat-resistant sheet that is flexible and can disperse and transmit light has an upper opening 2A and a lower opening 2B each having a predetermined diameter at both upper and lower ends of the center. Have.

  As shown in FIG. 1, the illumination support structure 3 has a plurality of support posts 6 erected around the upper surface of the blower 5 in which a plurality of air blowing holes 5 </ b> A are formed at the upper center, A support plate 7 having a shape is mounted and fixed. Further, in the center of the lower surface of the support plate 7, an illumination lamp 4 connected to an external power source 13 via a cable 14 is provided in a suspended manner. Although the illumination lamp 4 is fixed to the lower surface of the support plate 7 in the illustrated example, it can be attached to the support plate 7 so that the vertical position can be adjusted as necessary.

  A heat-resistant protective net 8 is disposed outside the support 6 and a transparent film sheet 9 having various colors such as red, blue and yellow is stretched outside the protective net 8. The film sheet 9 can be removed when only the illumination lamp 4 needs to be illuminated. A hook-and-loop fastener or the like can be used as the attaching / detaching means at that time.

  On the outer side of the support plate 7 of the illumination support structure 3, a ring-shaped upper mounting cover 10 is attached by, for example, welding the peripheral edge of the center hole, and an upper opening 2A provided at the upper end of the membrane structure 2 is provided. An arbitrary fixing means 12 is detachably attached to the outer peripheral side of the upper mounting cover 10 by, for example, a slide fastener, a hook-and-loop fastener, a male / female button, or the like.
