Description
REFLECTORREFLECTOR
De uitvinding betreft een reflector voor het zo uniform mogelijk verspreiden van licht.The invention relates to a reflector for distributing light as uniformly as possible.
Met name in de glastuinbouw wordt assimilatie-belichting toegepast. Door deze verlichting wordt de produk-tie van het gewas verhoogd en de kwaliteit verbeterd. Met name in het jaargetijde dat de natuurlijke inval van licht beperkt is, is verlichting van essentieel belang. Het is het doel van de uitvinding een reflector te verschaffen waarvan de lichtopbrengst zo uniform mogelijk is. Dit komt tot uiting in een zo regelmatig mogelijk verloop van het zogenaamde polaire diagram.Assimilation lighting is used in greenhouse horticulture in particular. This lighting increases crop production and improves quality. Especially in the season when the natural incidence of light is limited, lighting is essential. The object of the invention is to provide a reflector whose light output is as uniform as possible. This is reflected in the most regular course of the so-called polar diagram.
Dit wordt volgens de uitvinding bereikt door het verschaffen van een reflector bestaande uit een ongeveer half bolvormig lichaam met ten minste twee loodrecht op elkaar staande symmetrievlakken, middelen voor het op ongeveer het snijpunt van de symmetrievlakken opstellen van een verlich-tingselement, aan weerszijden van één van de symmetrievlakken in het oppervlak van de bol aangebrachte eerste reliëfvlakken en aan weerszijden van dat symmetrievlak op grotere afstand tot dat symmetrievlak dan de eerste aangebrachte tweede reliëfvlakken.This is achieved according to the invention by providing a reflector consisting of an approximately hemispherical body with at least two perpendicular symmetry planes, means for arranging a lighting element at approximately the intersection of the symmetry planes, on either side of one of the symmetry planes arranged in the surface of the sphere, first relief planes on either side of that symmetry plane at a greater distance from that symmetry plane than the first second relief planes applied.
Praktijkproeven hebben uitgewezen dat een reflector met reliëfvlakken volgens de uitvinding een regelmatig polair diagram van de gewenste vorm opleveren.Practical tests have shown that a reflector with embossed surfaces according to the invention produces a regular polar diagram of the desired shape.
Volgens een voorkeursuitvoering zijn van de tweede reliëfvlakken de oppervlakken groter dan die van de eerste. Ook is de plaatsing van de reliëfvlakken bij voorkeur zodanig dat deze symmetrisch liggen ten opzichte van beide symmetrievlakken.According to a preferred embodiment, the surfaces of the second relief surfaces are larger than those of the first. The placement of the relief surfaces is also preferably such that they lie symmetrically with respect to both symmetry surfaces.
De uitvinding wordt aan de hand van de tekeningen nader verduidelijkt.The invention is further elucidated with reference to the drawings.
In de tekeningen toont:In the drawings shows:
Fig. l een perspectivisch aanzicht van de reflector volgens de uitvinding, fig. 2 een doorsnede-aanzicht van de reflector uit fig. 1, en fig. 3 een doorsnede-aanzicht vanuit een stand die ten opzichte van die uit fig. 2 over 90° is gedraaid.Fig. 1 is a perspective view of the reflector according to the invention, fig. 2 is a cross-sectional view of the reflector of fig. 1, and fig. 3 is a sectional view from a position which is 90 ° relative to that of fig. 2 rotated.
De reflector 1 heeft een half bolvormige stand en is voorzien van aansluitmiddelen 2 voor het bevestigen van een lichtelement. In de reflector zijn een tweetal loodrecht op elkaar staande symmetrievlakken te herkennen, te weten één symmetrievlak in langsrichting en één middendeelsymmetrievlak in een stand loodrecht daarop. Symmetrisch ten opzichte van de symmetrievlakken zijn series eerste reliëfvlakken 3 en 4 aangebracht. Op afstand van de reliëfvlakken 3, 4 zijn tweede reliëfvlakken, waarvan er één 5 zichtbaar is, op grotere afstand van het symmetrievlak dan de eerste reliëfvlakken aangebracht. Het oppervlak van het reliëfvlak 5 is groter gekozen dan de deelvlakken van de series reliëfvlakken 3 en 4.The reflector 1 has a hemispherical position and is provided with connecting means 2 for attaching a light element. Two reflecting planes perpendicular to each other can be recognized in the reflector, namely one longitudinal symmetry plane and one mid-section symmetry plane in a position perpendicular thereto. Series of first relief surfaces 3 and 4 are arranged symmetrically with respect to the symmetry planes. At a distance from the relief surfaces 3, 4, second relief surfaces, one of which is visible, are arranged at a greater distance from the symmetry plane than the first relief surfaces. The surface of the relief surface 5 is chosen to be larger than the partial surfaces of the series of relief surfaces 3 and 4.
