Description

[Detailed Description of the Invention] The present invention relates to a lighting device for an indoor greenhouse, which has a box-shaped configuration by installing horizontal beams between pillars set up at the four corners of an underframe, and a glass panel is attached to the peripheral surface.

Conventionally, this type of indoor greenhouse lighting has generally been achieved by suspending a fluorescent lamp with an integrated ballast from the top via a hanging metal fitting. However, with the above conventional configuration, there is a problem that the suspended fluorescent lights narrow the usable space in the greenhouse, which hinders the arrangement and growth of ornamental plants, and also impedes ornamental viewing. The drawback was that it required time and effort to install. Furthermore, different types of hanging metal fittings are required depending on the mounting position of the fluorescent lamp.

The present invention was developed in order to eliminate the above-mentioned drawbacks of the conventional technology, and has various advantages such as a wider usable space, the fluorescent lamp itself being less noticeable, and the fluorescent lamp being extremely easy to install. The purpose is to provide a lighting device with

Hereinafter, the present invention will be explained based on illustrated embodiments.

In Fig. 1, reference numeral 1 is an indoor greenhouse constructed in the shape of a vertically elongated box. Supports 3 made of extruded aluminum or its alloy are attached to the four corners of a rectangular frame 2.
3... are erected, and between the top and intermediate positions are upper and lower crosspieces 4a, 4b, 4c, 4d and middle crosspieces 5a, 5 made of extruded materials in the same way.
b, 5c, 5d are constructed, and glass panels 6, 6... are fitted on the top surface and the entire circumferential surface.
A rod-shaped fluorescent light tube 7 is attached to the lower surface side of the front upper crosspiece 4a and the front middle crosspiece 5a, and the ballast 8 is connected to the wiring (not shown) inside the support column 3 to connect the underframe 2. The glass panels 6a, 6a, . It is possible to do this from

As shown in FIGS. 2 and 3, the front upper crosspiece 4
a is a hollow frame with a substantially L-shaped cross section, and has hollow parts 9a and 9b partitioned into upper and lower parts, with a lower hollow part 9
A downward U-shaped upper rail frame 10 into which the upper ends of the front glass panels 6a, 6a are slidably fitted is provided below b, and a receiving piece supporting the top glass panel 6 is provided at the rear edge of the upper part. 11 has been extended.
Thus, a light reflecting curved surface section 12 having a substantially arcuate cross section is formed along the longitudinal direction of the upper crosspiece 4a by the lower surface side of the upper hollow section 9b and the arcuate piece 12a protruding diagonally downward inward from the middle thereof. Furthermore, a sliding groove 13 is formed on the inner surface of the lower hollow portion 9b along the longitudinal direction of the upper crosspiece 4a. On the other hand, the front middle crosspiece 5a
is a hollow frame with a substantially L-shaped cross section, and has hollow parts 9c and 9d divided into upper and lower parts, with a lower hollow part 9d
An upper rail frame part 1 similar to the front upper rail 4a is installed below the front upper rail 4a.
0, and a fitting groove 14 is formed on the upper surface side of the upper hollow portion 9c, and the lower rail frame member 15 of the front glass panels 6a, 6a is inserted into the fitting groove 14 in the engaging leg portions 15a on both sides. are mated and fixed.
Thus, a curved surface portion 12 for light reflection similar to that of the front upper crosspiece 4a is constituted by the arcuate piece 12b protruding from the inside of the upper part of the front middle crosspiece 5a, and the inner crosspiece 5a is further formed on the inner surface side of the lower hollow part 9d. A sliding groove 13 is formed along the longitudinal direction.

A sliding groove 13 is provided at a position directly below the light reflecting curved surface portion 12 of the front upper crosspiece 4a and the front middle crosspiece 5a, respectively.
A pair of cylindrical sockets 17 are attached to a pair of socket holders 16 that are slidably fitted into the socket.
A fluorescent tube 7 is attached via the . This socket holder 16 consists of a back metal 18 that is approximately U-shaped in side view and is fitted into the inside of the sliding groove 13, that is, the lower hollow portions 9b and 9d, and a bifurcated leg portion that protrudes from the circumferential surface of the socket 17. 17a is sandwiched and supported from the outside by both edge pieces 19a, and a base metal 19 is screwed with screws 20 passing through the inside and outside of the sliding groove 13.
Both ends of the side pieces 18a of the back metal 18 are cut to form leaf spring pieces 18b that extend outward, and these leaf spring pieces 18b form the hollow portion 9.
By being in elastic contact with the upper and lower inner wall surfaces of holes b and 9d, the socket holder 16 is stably held in the set position of the sliding groove 13 so that it will not move due to vibration etc. maintenance is done. 19b is a screw hole in the base metal 19, 21 is an electric wire led out from the socket 17, and is connected to the sliding groove 13.
It is connected through the strut 3 to a ballast 8 and an external power connection.

In the above-mentioned embodiment, the fluorescent light tube 7 is provided on the front side of the greenhouse 1 to indirectly illuminate the ornamental plants.
The fluorescent light tube 7 may be attached to either or both of the rear middle beam 5b and the rear middle crosspiece 5b, or it may be attached only to the rear side. Furthermore, in order to make the greenhouse 1 multi-tiered, etc., middle beams 5a, 5b, and 5c are used.
5d may be provided at a plurality of height positions, and in this case, the number of fluorescent light tubes installed can also be changed in various ways. On the other hand, since the arcuate pieces 12a and 12b are provided as constituent parts of the light reflecting curved surface part 12 in the embodiment described above, there is an advantage that the ends thereof also function as draining pieces. It would be good if it could function as a reflective umbrella.

As described above, the lighting device for an indoor greenhouse according to the present invention has a curved surface for light reflection and a sliding groove formed on the lower surface side of at least one horizontal beam on the front side or the rear side, and the sliding groove in the sliding groove. The pair of socket holders are slidably fitted, a rod-shaped fluorescent light tube is attached via the socket attached to each socket holder, and the ballast of the fluorescent light tube is attached to the underframe of the greenhouse. Because they are fixed inside, the fluorescent lamps do not restrict the usable space in the greenhouse and do not interfere with the arrangement and growth of ornamental plants.The fluorescent lamps are not conspicuous, so the appearance and ornamentation are improved. does not inhibit. Furthermore, there is no need for conventional hanging metal fittings or their support members, and the horizontal beam itself can be fitted via the socket holder, making installation and removal very easy and quick, and the installation position can be adjusted horizontally. It has the advantage that it can be adjusted arbitrarily. Furthermore, by being installed on the bottom side of the horizontal beam, the fluorescent light part is waterproof against water from above, so you can replenish water to plants without worrying about water leaking or malfunctioning, and the light reflecting off the horizontal beam itself is waterproof. Since it has an umbrella function, there is no need for reflective umbrellas, which are aesthetically pleasing and hinder the use of space.
