Definitions
- the invention relates to a mast luminaire with a mast, at least one launcher unit attached to it, equipped with a lamp and primary reflector, and at least one secondary reflector carried in the upper region of the mast for deflecting the light thrown upwards by the launcher unit (s) a floor area next to the mast.
- mast lights are used in particular to illuminate squares or streets.
- Classic street lights generally have one or more light sources and primary reflectors at the top of a column, which distribute the light downwards.
- mast luminaires based on the secondary reflector principle have also become known in which a projector throws light upwards, where it is distributed downwards by secondary reflectors.
- secondary reflectors in the form of inclined flat mirrors are known.
- the object of the invention is to provide an improved mast luminaire in which a direct view of the illuminant (lamp) is avoided and with which a predetermined, preferably uniform, illumination of the floor surface is achieved.
- precise masking should be possible outside of a desired radiation range.
- the secondary reflector has a plurality of reflector facets lying next to one another, each preferably concavely curved below, the shape and / or orientation of which varies over the secondary reflector surface.
- the secondary lamp principle prevents a direct view of the illuminant or the lamp.
- a primary reflector in the area of the upper mast end directs the radiation from the lamp upward onto the secondary reflector, which according to the invention is designed as a facet field and distributes this radiation downward onto the useful plane (floor surface).
- the individual side-by-side reflector facets, each concavely curved at the bottom vary in shape and / or orientation over the secondary reflector surface. This makes it possible to reduce the radiation distribution optimize because every facet can optimally distribute the light component coming from the primary reflector to the usable area or parts thereof.
- the entire illuminance distribution as a superimposition of the illuminance distribution in the individual facet can thus be precisely specified, in particular a uniform illumination of the floor area can be achieved by the mast luminaire
- the free-form geometry of the individual reflector facets not only enables the illumination to be optimized, it is also possible to achieve good masking outside the desired radiation range
- the shape or orientation of the reflector facets varies over the secondary reflector surface according to the invention.
- This makes it possible to design the facet shape of the individual reflector facets differently, and preferably not according to a specific geometric curve, such as a parabola or the like, but rather a calculated free-form surface to be provided so that the predetermined area to be illuminated is illuminated exactly according to a predetermined illuminance distribution. It is thus possible, for example, to design the facets so that they appear the same size when viewed from an observer's point of view
- a large light exit surface can be achieved, with which the average luminance in the radiation area can be limited to below 5000 cd / m 2 , which considerably reduces glare Primary light source in many small light spots according to the number of facets. This further reduces glare
- FIG. 1 shows an exemplary embodiment of a mast luminaire according to the invention in a perspective view obliquely from below
- FIG. 2 shows a partial view of the upper region of this mast luminaire
- FIG. 3 shows a schematic cross section through the secondary reflector surface of a mast luminaire according to the invention
- 4 schematically shows the shape of a reflector facet of the facet field according to the invention of the secondary reflector surface
- FIGS. 5 and 6 each show exemplary embodiments of a projector unit with a lamp and a reflective reflector
- the mast light shown in FIG. 1 stands on a floor surface 1 and has a mast column 2, on the upper end of which there is a projector unit, which, as will be described later in FIGS. 5 and 6, has a reflecting reflector and a lamp on this projector unit Light directed upwards onto the secondary reflector 4, which is held by a schematically represented holding device 5.
- this holding device 5 can consist of one or more as thin rods as possible.
- the secondary reflector 4 distributes the light thrown upwards by the throwing unit 3 evenly downwards onto the floor surface 1 adjacent to the masts 2
- the shape varies with the alignment of the individual reflector facets 6 over the secondary reflector surface, which enables an optimization of the light distribution is arranged
- the reflector facets of the secondary reflector 4 are preferably attached or formed on one or more flat support surfaces of a support 7.
- a support 7 In the embodiment shown in FIGS. 1 to 3 there are two spaced flat surfaces 4a and 4b.
- the surface 4b is opposite the surface 4a lowered in the central area.
- the side walls 8 of the lowered area are preferably mirrored.
- the secondary reflector 4 is rectangular, namely square. Other reflector dimensions can of course also be provided.
- the most uniform possible light distribution is achieved by the fact that the reflector facets 6 further away from the mast axis 9 are inclined more towards the mast axis 9 than the reflector facets 6 closer to the mast axis 9, as shown in FIG.
- the shape of the reflector facets 6 also varies over the surface.
- the outer reflector facets 6 are inclined at a larger angle ⁇ 2 more towards the mast axis than the closer reflector facets, which are inclined at the angle o ⁇ .
- the reflector facets themselves are concavely curved downward, that is to say they have a concave, high-gloss underside 6a, as is shown by way of example in FIG. 4.
- the reflector facet shape is preferably a free-form surface that is determined by calculation.
- a primary reflector 10 distributes the light emitted by the lamp 11 upwards, the light exit opening being able to be closed off by a cover glass 12.
- this cover glass has the task of preventing contamination of the reflector which is open at the top and, on the other hand, can also have filter properties, for example UV filter properties.
