Document Type and Number:
WIPO Patent Application WO2002089559
Kind Code:
A3
Abstract:
The invention relates to an apparatus for assimilation illumination for installation in a greenhouse to cultivate light sensitive plants. The invention also relates to a mounting system and method upon which the illumination armature (6) will be installed. Illumination armature (6) with light source will be installed up in the ceiling section of a greenhouse structure. The accessory starter unit (14) will be located lower, in the proximity of the plant(s). By the application of this unique separated configuration there will be substantially less light interception as well as improved balanced temperature profile in the greenhouse space will be achieved. These are due to the heat generated by starter units that is now being utilized on a much lower level in a greenhouse. Supporting suspension elements, like steel wires, are mounted in the ceiling section (1) of a greenhouse structure. Illumination armature (6) is provided with special L-shaped holding means (7) and accessory connection piece (8). Illumination armature (6) is by means of a pair of metal- or synthetics made braces supported (hanged) upon a pair of parallelly running supporting steel wires. Fixing of the illumination armature (6) upon a pair of steel wires is obtained by fastening of a single brace. Undesired warping of illumination armature (6) at operating and non-operating times will be avoided accordingly. A chance for theft will be also reduced.
