DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent light fixture of a small double-roof greenhouse mainly used for growing and ornamental plants indoors.

[0002] In this specification, the term "aluminum" includes an aluminum alloy in addition to pure aluminum.

[0003]

2. Description of the Related Art Conventionally, in a double-roof type small greenhouse mainly used for growing and ornamental plants indoors, lighting of the greenhouse is usually performed by fluorescent lamps suspended from a purlin.

[0004]

However, when fluorescent lamps are hung on a purlin in a small double-roofed greenhouse, the installation work is troublesome.

[0005] Further, the conventional double-roof type greenhouse has a structure in which a wall plate such as a transparent glass plate or a roof plate is fitted into a frame made of an aluminum frame, but it requires time and labor for assembly work. Because of the problem, the present inventors have invented a simple greenhouse assembly case in which the adjacent wall plates and the wall plate and the roof plate arranged above these are connected by a connector. See Japanese Patent Application Nos. 6-249151 and 6-249152). (In this specification, the term “small greenhouse” includes the “greenhouse-style assembly case” described above.) However, since such a greenhouse-style assembly case does not have a purlin, There was a problem that the hanging fluorescent lamp fixture could not be used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and can be used for lighting a small greenhouse without a purlin for suspending fluorescent lighting equipment. It is an object of the present invention to provide a double-roof type compact greenhouse fluorescent lamp device that is simple.

[0007]

In order to achieve the above object, a double-roofed compact greenhouse fluorescent lamp apparatus according to the present invention is made of extruded aluminum material and has both edges of an opening provided at the top of the greenhouse. And an electric component mounting plate made of an extruded aluminum material and horizontally mounted inside the device main body. Both edges of the electric component mounting plate The groove into which the part is slidably fitted is formed in the longitudinal direction inside the instrument body.

[0008] At both ends of the instrument body, end covers usually made of synthetic resin or the like are attached. As a means for attaching the end cover to both ends of the instrument body, for example, a tap hole or a screw hole is provided in the instrument body, and the end cover is fixed with a tapping screw or a small screw. It is preferable that a ridge is formed at a required position inside the appliance body so that both edges of the opening at the top of the greenhouse abut. Further, it is preferable that one or more slits or holes for ventilation are formed in the appliance body.

Examples of the electric components mounted on the electric component mounting plate include, in addition to the socket, auxiliary devices necessary for starting and lighting the fluorescent lamp, such as a ballast, a starter (such as a glow starter), a frequency changeover switch, and a wiring cord. Can be However, a blinking switch, an external wiring cord, and the like may be attached to the end cover. As the fluorescent lamp, a straight tube fluorescent lamp is used.

The electric component mounting plate may be provided with a step by bending it in a crank shape at an intermediate position of its length, for example, so that the ballast is mounted on a lower horizontal portion. In the case where the above-mentioned step is provided on the electric component mounting plate, it is preferable that a ridge for receiving both edges of the lower horizontal portion is formed inside the appliance main body. The lower surface of the electric component mounting plate is subjected to polishing or the like, and the same surface functions as a reflection surface.

[0011]

According to the fluorescent light fixture of the double-roof type small greenhouse according to the present invention, when assembling and attaching to the small greenhouse,
It is only necessary to fit both edges of the electric component mounting plate on which the electric components are mounted into the grooves inside the appliance main body and place the appliance main body on both sides of the opening at the top of the greenhouse.
