BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of a mobile cart-mounted lighting apparatus for outdoor lighting, to which a lighting apparatus according to the present invention is attached. The illumination device 1 with a movable carriage includes a carriage 3 on which a power generation device 2 is mounted, a telescopic pillar 4 erected on the carriage 3, and lighting at the upper end of the pillar 4 A device 5 is provided. The telescopic support 4 is erected on the carriage 3 on which the power generation device 2 is mounted, and the light support 5 attached to the support 4 is widely used for lighting such as road construction at night. The embodiment shown in FIG. 1 differs from that of the prior art in the illumination device 5 mounted on the top of the column 4.

[0029] The power generation device 2 often uses one that also becomes a generator power driven by a diesel engine or a gasoline engine. It is small and inexpensive, can be manufactured economically, and is easy to handle including operation and maintenance. On the other hand, if noise is a problem and quietness is required, it is also possible to mount a rechargeable secondary battery or fuel cell.

The carriage 3 has wheels 3a rotatably supported at the front, rear, left, and right of the vehicle body base, and is formed so that the wheeled power generator 2 can be mounted so as to be attachable and detachable. Has been established. In addition, as for the power generation device 2, the power generation device may be directly mounted or fixed on the carriage 3 which does not have wheels.

The column 4 has a telescopic structure with several stages of cylindrical force. The respective cylinders can slide and expand and contract with each other, and the lighting device 5 can be set and held at a necessary height. Further, according to the specification, a gas damper can be incorporated into the interior of the cylinder to reduce the expansion / contraction force of the support 4 to an extent that it can be operated with one hand.

FIG. 2 is a cross-sectional view showing a first embodiment of a lighting device 5 according to the present invention. As shown in FIG. 2, the lighting device 5 comprises a balloon 7 having an expandable envelope 6 made of thin flexible material, and a reflecting cylinder 8 having a large diameter opening 8a attached to the opening 7a of the balloon 7. A holding cylinder 9 attached to the small diameter opening 8b of the reflecting cylinder 8, a blower 11 attached to the base of the holding cylinder 9, and an illumination lamp 12 on the air discharge side of the blower 11.

[0033] In FIG. 2, a balloon 7 having an expandable envelope 6 that also provides a thin flexible material force is fabricated with a material strength that is not transparent but has good light transmission. For example, cloth or plastic film can be used as the material. Using the balloon 7 of such material, the entire periphery of the balloon 7 can be illuminated with soft light. It is general to use a balloon 7 having a generally elliptical cross section after being expanded, but a balloon 7 of various shapes can also be used. For example, the shape of stuffed animals or anime It can also be in the form of a character. By using a balloon having such a character shape or the like, a mere lighting device can also be used as a customer attraction device for events such as a night festival that is not.

An annular fastener 13 is attached to the opening 7 a of the balloon 7 as a fixing tool. The other annular fastener 14 corresponding to the annular fastener 13 is attached to the large diameter opening 8 a of the reflecting cylinder 8, and the annular fastener 13 attached to the opening 7 a of the balloon 7 is The balloon 7 is detachably fastened via the cover. The fasteners may be Velcro (registered trademark) or a band instead of the annular fasteners 13 and 14.

The reflective cylinder 8 has a tubular shape having a large diameter and a small diameter made of a metal plate, and as described above, the other annular fastener 14 for attaching the balloon 7 is fixed to the large diameter opening 8a. It is done. As a method of attaching the other annular fastener 14 to the large diameter opening 8a of the reflecting cylinder 8, for example, the other annular ring is provided between the flange 8c provided at the large diameter opening 8a of the reflecting cylinder 8 and the annular clamping plate 15. The fastener 14 can be held and fixed by the bolt 16 and the nut 17. Further, the small diameter opening 8b of the reflecting cylinder 8 is fixed to the opening 9a of the holding cylinder 9 having a cylindrical shape.

The reflective cylinder 8 is usually made of an aluminum plate for light weight, and the cylindrical inner surface 8 d to be a light reflecting surface is mirror finished by polishing. Therefore, it has high light reflectance. Further, since the reflecting cylinder 8 is for projecting light emitted by the illumination lamp 12 to the top side 7b of the balloon 7, as shown in FIG. 2 from the relationship between the incident angle of light and the reflection angle. The side to which the opening 7a of the balloon 7 is attached corresponds to the large diameter opening 8a of the reflection plate 8. Furthermore, the inner surface 8d of the reflecting cylinder 8 has a gentle concave shape in order to focus the light beam of 12 powers of the illumination lamp.

Although the reflective cylinder 8 is usually made of a metal material such as an aluminum plate, it can also be made of a transparent or semi-transparent synthetic resin or the like according to the specification. When the reflecting cylinder 8 is made of a transparent or translucent member, it is possible to pass light of a level which does not reflect light on the inner surface of the reflecting cylinder 8.

In the holding cylinder 9, a blower 11 for delivering air to the inside of the balloon 7 and an illumination lamp 12 are provided. It is attached. As the blower 11, an axial flow fan having a motor built in the core of the fan can be used. This axial fan is mass-produced for cooling electronic devices and has the advantage of being inexpensively available in the general market.

An illumination lamp attachment network 18 is provided on the air discharge side 11 a of the blower 11, a socket 19 for attaching the illumination lamp 12 is attached to the illumination lamp attachment network 18, and the illumination lamp 12 is attached to the socket 19. ing. It should be noted that since the lighting lamp attachment grid 18 is a net only for holding the socket 19 and the lighting lamp 12, the air flow from the blower 11 which disturbs the air flow from the blower 11 is an illumination lamp, It is sent into the balloon 7 through between 12 and the inner surface 8 d of the reflecting cylinder 8. As a result, the air pressure in the balloon 7 is increased, and the balloon 7 can maintain the inflated state. The inside of the balloon 7 is kept in balance at a pressure enough to maintain the inflated state of the balloon 7 in a completely airtight state. Specifically, air comes out with an appropriate resistance from the annular fasteners 13 and 14 which attach the balloon 7 to the large diameter opening 8 a of the reflecting cylinder 8.

A wire through hole 9 b for passing a wire for supplying electric power to the blower 11 and the illumination lamp 12 is provided on one side surface of the holding cylinder 9.

A through hole 22 is provided in the base 9 c of the holding cylinder 9 at a position corresponding to the air suction port l ib of the air blower 11.

In the lighting device 5 having such a configuration, when the blower 11 and the illumination lamp 12 are energized, the balloon 7 is inflated by the air flow delivered from the blower 11. The light emitted from the illumination lamp 12 is reflected by the inner surface 8d of the reflecting cylinder 8 and reflected from the top 7b side of the balloon 7, and a large amount of light is projected from the side of the top 7b of the balloon 7. The entire periphery can be illuminated with soft light and the top 7 b side of the balloon 7 can be illuminated more brightly. Further, since the illumination lamp 12 can be cooled by the blower 11, the external dimensions of the illumination device 5 can be made compact. Therefore, even if it is necessary to illuminate the entire surroundings of the mobile cart-mounted lighting device 1 with soft light and to illuminate a particular direction particularly brightly, it is sufficient to prepare only one mobile cart-mounted lighting device 1. .

FIG. 3 is a cross-sectional view showing a second embodiment of a lighting device 5 according to the present invention. The second embodiment is the first embodiment in that a protective frame 23 for protecting the illumination lamp 12 is provided in the holding cylinder 9. It is different from the form. The protective frame 23 is usually formed into a rough cocoon-like shape by a metal wire so as to minimize the light S that the illumination lamp 12 force is radiated, and is attached to the illumination lamp attachment network 18. Further, the top 12a of the illumination lamp 12 for holding the illumination lamp 12 in a stable manner is held by the protective frame 23.

As described above, by providing the protective frame 23 in the holding cylinder 9, the protective frame 23 protects the illumination lamp 12 even when the illumination device 5 is stored or transported. We can prevent wounds.

FIG. 4 is a cross-sectional view showing a third embodiment of a lighting device 5 according to the present invention. In the third embodiment, the transparent plate 25 is attached to the large diameter opening 8a of the reflecting cylinder 8 in a non-airtight manner. The transparent plate 25 is usually made of a resin material such as acrylic or polycarbonate to avoid damage due to contact or the like. Of course, it is possible to manufacture the transparent plate 25 with a glass plate material, but manufacturing the transparent plate 25 with a glass plate material has the disadvantage that the weight is increased and it is vulnerable to damage. The transparent plate 25 is provided with holes 25a for ventilation at a plurality of locations, and even if the transparent plate 25 is provided, the space between the front and back of the transparent plate 25 is not airtight. Therefore, the air flow delivered by the blower 11 can flow into the balloon 7 through the vent holes 25a provided in the transparent plate 25, so that the balloon can be inflated and generated from the illumination lamp 12. Heat can be discharged to the outside. In addition to the method of attaching the transparent plate 25 to the reflective cylinder 8, in addition to the method of attaching with the bolt 16 and the nut 17, a fixing bracket having a substantially U shape around several places of the flange 8 c of the reflective cylinder 8 ( It can also be attached to the reflecting cylinder 8 by rotatably attaching the not shown) and holding the transparent plate 25 using the fixing bracket.

Thus, by attaching the transparent plate 25 to the large diameter opening 8 a of the reflecting cylinder 8 in an airtight manner, the illumination plate 12 is protected by the transparent plate 25 even when the illumination device 5 is stored or transported. Be done. In addition, if the balloon 7 is removed by operating the annular fasteners 13 and 14 as necessary, it can be used as a normal floodlight.

As described above, by providing the cylindrical body 26 made of flexible material in the lane 7, the air inside the cylindrical body 26 made of flexible material is pressurized by the air sent from the blower 11. As a result, the top 7 b of the jacket 6 constituting the well 7 can be supported securely. In addition, since the air flow flows into the inside of the jacket 6 from the vent holes 27 provided in the cylindrical body 26, the jacket 6 can also be inflated. Therefore, the rigidity of the balloon 7 is improved, and the stable balloon 7 shape can be maintained even under strong wind. When a transparent resin is used as the material of the cylindrical body 26, the amount of light emitted from the outer cover 6 of the valve 7 is hardly reduced !, so the intrinsic brightness of the balloon 7 is obtained. There will be no decline. Also, the same material as that of the balloon 7 can be used for the material of the cylindrical body 26.

In the present embodiment, not only the annular fastener 13 as a fixing member is attached to the opening 7 a of the outer cover 6 of the balloon 7, but the same annular fascia is also attached to the top 7 b of the balloon 7. 28 is attached. And, an annular fastener 29 is attached to the corresponding position on the top 7 b side of the balloon 7. As a result, the jacket 6 can be attached and detached by operating the annular fasteners 13, 14, 28, 29 as necessary.

FIG. 6 is a cross-sectional view showing a fifth embodiment of a lighting device 5 according to the present invention. In the fifth embodiment, an electronic ballast 31 is disposed in the holding cylinder 9 to stabilize the illumination lamp 12.
