Description

APPARATUS FOR ASSIMILATION LIGHTING AS WELL AS FIXING SYSTEM AND METHOD FOR INSTALLATION THEREOF IN A GREENHOUSE

The invention relates to apparatus for installation in a greenhouse structure in the modern greenhouse horticulture to cultivate light sensitive plants. The invention also relates to a mounting system and method for installation of the illumination armature in the upper (ceiling) section of the greenhouse construction that is provided with suspension members such as e.g. a pair of parallelly running supporting wires as well as to the separate accessories. Well-considered configuration of the integral parts of apparatus will boost the efficiency of the assimilation illumination; illumination armature with light source will be mounted up in the upper (ceiling) section of a greenhouse structure while the accessory starter unit will be separately positioned substantially lower, in the immediate proximity of the plant(s), by means of a suitable mounting element.

In the modem greenhouse horticulture for cultivation of light sensitive plants assimilation illumination will be used, which mainly consists of a number of illumination units, depending on the plant type and total space in a greenhouse. An illumination unit is principally built from the following elements: a) starter unit containing igniter, transformer, condenser and accessory electronics, all located in a metal housing and b) illumination armature, which consists of reflector and lamp holding means, containing one or more light sources such as incandescent lamps, gas discharge lamps or the like; whereby all mentioned elements are enclosed and mounted respectively on the suitable supporting construction members of the ceiling section of a greenhouse.

This configuration involves a number of disadvantages which have influence on the total efficiency of greenhouse horticulture, namely: a) substantial light interception, created by a plurality of mentioned illumination armatures being located under the light permissive roof/ceiling section of a greenhouse during the daylight phase period and b) largely unbalanced temperature distribution over the vertical profile of internal space of a greenhouse as a consequence of the heat build-up caused by the heat emission of a plurality of lamps as well as starter units in the upper section of a greenhouse. Applying the new apparatus according to invention will substantially decrease these disadvantages. The essence of the invention resides in splitting of the earlier mentioned illumination unit, whereby the starter unit (igniter, transformer, condenser and accessory electronics, all enclosed in a massive metal housing) will be purposely configured remote from illumination armature that is provided with one or more light sources (one or more incandescent lamps, gas discharge lamps or the like).

Remotely configured illumination armature is further provided with a special L-shaped holding means and a connection piece, which connects reflector element with lamp- and L-shaped holding means in a single compact unit, all produced of metal, synthetics or a combination therefrom. The L-shaped holding means are aiding the installation of the armature without starter unit by means of fixing mounting means in the ceiling section of a greenhouse, which is accordingly being provided with e.g. at least one pair of supporting suspension members, such as e.g. steel wires or one or more C, U, I, H, L, T, round, flat or square, tube- or bar shaped profiles.

On the other side the accessory starter unit will be installed at a lower position in the greenhouse in the immediate proximity of the plants by means of a suitable mounting element. First advantage resides in decreasing the undesired light interception whereby (otherwise) a substantial number of square meters of the total area of a plurality of illumination armatures does not restrict the light input at the daylight phase period anymore. Secondly, by means of relocating the heat emitting part of the starter unit to the lower greenhouse section a technical effect of an improved balanced temperature distribution in the greenhouse space will be also achieved. The mounting system for mounting of the mentioned upper unit in the ceiling section of a greenhouse construction comprises the following parts: a) a pair of parallelly running carrying suspension wires mounted on the desired illumination height up in an upper (ceiling) section of a greenhouse; b) a pair of uniquely shaped braces, produced of a deformable material such as e.g. of a suitable metal or synthetics and shaped as such that by multiple repetition of the mounting operation there will be no or very little residual negative influence (tiredness) occurring on the mechanical properties thereof; whereby each saddle cavity in/at the said braces fits optimally onto the said wires, by which the required fixing deformation, i.e. bending force in the brace required by the tool is minimal; c) mounting means for mounting of a pair of braces on the illumination armature, by using therefore suitable means, such as e.g. a screw connection.

The invention shall be described hereafter on the basis of an example of embodiment with a help of the drawings:

Fig. 2 shows a perspective view of the illumination armature according to invention installed up in the ceiling section of a greenhouse; Fig. 3 shows a perspective view of the starter unit according to invention installed down in an immediate proximity of the plants; Fig. 4 shows schematically (in perspective) the arrangement of a greenhouse space according to invention; Fig. 5 shows schematically (in a side view) arrangement of a greenhouse space according to invention; Fig. 6 shows a perspective view of an example of embodiment of an illumination armature according to invention; Fig. 7 shows a perspective view of an example of embodiment of a starter unit according to invention; Fig. 8 shows a perspective view of illumination armature according to invention, which is installed in the roof/ceiling section of a modern greenhouse; Fig. 9 shows a perspective view of a detail of the mounting system according to invention; Fig. 10 shows a perspective view of a detail of the mounting system according to invention; Fig. 11 shows a perspective view of a detail of the mounting system according to invention en

Fig. 12 shows schematically in a perspective view the uniquely shaped braces according to invention.

Fig. 1 shows a perspective view of the roof/ceiling section of a modern greenhouse with known illumination units 2 for assimilation illumination mounted therein. Suspension elements 3 of illumination unit 2, as well as the electrical main feeding cables (220V) 4 that are mounted in/on a C-shaped supporting profile, are also visible.

The apparatus for assimilation illumination according to invention, shown in Fig. 2, consisting of a separate illumination armature 6 with light source unit, is located in the ceiling section 1 of a greenhouse. Illumination armature 6 is provided with a special L-shaped holding means and a connection piece 8, whereby reflector element 9, lamp holder (not shown) and L-shaped holder 7 respectively are connected in a single compact unit. Also visible is the electrical feeding cable (110V) 10 that is connected to the starter unit 14 (not shown), see Fig. 3. L-shaped holding means 7 of the apparatus are mounted on the suitable pair of steel wires 12a and 12b by using mounting means 11 , which steel wires 12a are integrated in the ceiling section of a greenhouse. Fig. 3 shows a perspective view of the starter unit 14, which by locating lower than armature and mounted in an immediate proximity of the plant(s) 13 achieves much less light interception as well as a better temperature profile for plants in a greenhouse. Starter unit 14 is provided with a ribbed housing 15 for boosting the heat exchange. C-shaped carrying profile 16 and electrical main feeding cable 4 are also visible.

Fig. 4 shows schematically and partly in perspective the division of a greenhouse space whereby in the upper roof/ceiling section 1 of greenhouse a plurality of illumination armatures 6 is mounted with an aid of tensioned steel wires 12. Furthermore shows this Fig. 4 a configuration of a plurality of starter units 14, plants 13, C-shaped supporting profiles 16 and substrate gutters 18, all hanged up on chains 22. Known heating elements 17 are located on the greenhouse floor. Typical embodiment in Fig. 4 shows furthermore that a distance between the two greenhouse stands 9 equals e.g. 8m and the distance between the substrate gutters 18 equals e.g. 1.6m as shown in a side view of a greenhouse.

Fig. 5 shows schematically in a side view a configuration of a typical embodiment that is identical to the one shown in Fig. 4, whereby the distance between the two greenhouse stands 19 equals e.g. 5m and the distance between the two illumination armatures 6 equals e.g. 2.5 m.

Fig. 6 shows in a perspective view an another embodiment of the illumination armature according to invention, whereby L-shaped holding means, connection piece and lamp holding means respectively are enclosed in a compact integrated supporting means 21 (unit) of illumination armature 6 (not shown complete). Fig. 7 shows a perspective view of an embodiment of the starter unit 14 according to invention.

In Fig. 8 are the supporting means 21 for illumination armature 6 on the top side provided with a pair of uniquely shaped braces: front brace 23a and rear brace 23b. Both braces 23a and 23b are on the top provided with a saddle 24 and on the bottom side provided with a little foot plate 25 respectively. A pair (or a plurality-) of parallelly running supporting wires 3a and 3b is mounted at the desired illumination height up in the upper (ceiling) section of a greenhouse. Supporting means 21 for illumination armature 6 are by means of a pair of uniquely braces 23a and 23b supported (hanged up) on the said parallelly running supporting wires 12 and 12 b. As shown in Fig. 9 is the little foot plate 25 of the front brace 23a provided with a tongue 27 and a bore (not shown). By using said provisions the front brace 21 will be fastened onto the top surface of the supporting means 21 , of the illumination armature 6, which is provided with a corresponding groove 28 by means of a combined tongue-and groove and screw connection 29. Both braces 23a and 23b, which are produced of aluminium, are mutually dimensioned as such that each saddle 25 optimally fits onto the steel wires 12a and 12b by which the required fixing deformation, i.e. bending force caused by a suitable hand tool such as e.g. a pair of pincers or combination pliers, in the brace is minimal.

Method for mounting an illumination armature 6 upon a pair of parallelly running supporting wires 12a and 12b includes the following measures: a) locating a supporting means 21 of the illumination armature 6 provided with a pair of uniquely formed braces 23a and 24b respectively upon steel wires 12a and 12b respectively; b) positioning the illumination armature 6 lengthwise upon the steel wires 12a and 12b at the (desired) mutual distance for the final installation; c) fastening the rear brace 23b upon the steel wire 12b, like shown in Fig. 10 and 11 , by means of a suitable hand tool such as e.g. a pair of pincers or combination pliers (hand tool is not shown); by which the supporting means 21 of illumination armature 6 is fixed by avoiding an undesired warping at operating or non-operating times of the illumination. A chance for theft will be reduced accordingly.

In order to illustrate this configuration a pair of uniquely shaped braces 23a and 23b on the steel wires 12a and 12 b respectively is separately shown in Fig.12

(illumination armature is hereby not shown). Instead of aluminium as brace material there can be also an another deformable material used, such as e.g. another metal or synthetics, providing that by multiple repeated mounting operations there will be no or very little residual negative influence (tiredness) occurring on the mechanical properties thereof.

In another greenhouse embodiment the roof/ceiling construction will be substantially relieved of the high weight load of plurality of starter units by means of having these located e.g. on a structure that is supported by the floor.

In another example of embodiment there can be two or more illumination armatures connected on a single starter unit.

Considerable benefits will be created by an optimum utilization of the heat generated by starter unit, which can be received by the surrounding growing plants at the lower level according to invention.

During the daylight a substantial decrease of light interception will be also achieved by having the shading caused by starter units, which are normally being located high up in a greenhouse, now only occur underneath the plant gutters.
