Definitions
- the present invention relates to a reflector assembly for a luminaire, wherein the reflector arrangement has a plurality of reflector chambers arranged in series, over which the light emitted by a light source is radiated.
- Reflector arrangements of this type are usually used when to be avoided by the light emitted by a light Glares occur.
- the individual reflector chambers of the arrangement are for this purpose configured such that the light emitted from the light source only under certain angle ranges the lamp can leave. These areas are like that chosen that a person located diagonally below the lamp not directly can look into the light source.
- Reflector arrangements also reflections on vertically arranged surfaces be avoided within a room to be illuminated.
- the directed after down radiated light can thus be used in particular also Office space with computer workstations to light.
- the light source as one or more elongated gas discharge lamps, in particular Have fluorescent tubes.
- One in light emission direction in front of the light source arranged reflector assembly is then also elongated and consists of several arranged in series reflector chambers.
- ring-shaped luminaires are also known which have a circular arc Have light source.
- the reflector assembly also has a Ring structure, which is to be arranged in the emission in front of the light source.
- Reflector assemblies of the type discussed above may be characterized, for example be created that initially two spaced apart from each other and essentially be provided parallel to each other reflector walls by several Rastquerstege be connected together.
- the Rastquerstege point usually a slight V-shape and divide the overall arrangement in juxtaposed reflector chambers.
- Such constructions have become Although proven so far, but it is only possible with great effort, To achieve more complex structures for the reflector assembly.
- Already ring-shaped Reflector arrangements according to the above construction can only with great Effort to be created.
- the present invention is therefore based on the object, a Possibility to specify reflector arrangements in different forms and To produce lengths in the simplest possible way.
- the invention also has Arrangement a plurality of arranged in series reflector chambers.
- the reflector chambers or groups thereof are separate elements, which are suitable and intended for assembly, such that they as a whole form the reflector assembly.
- the core idea of the present invention is thus, the reflector arrangement not as previously from side reflector walls and interposed Rastquerstegen instead of forming individual separate elements into a whole Assemble arrangement, the individual elements at least one Include reflector chamber. It is a modular system, so to speak placed in which the separate elements in the desired manner can be assembled. In particular, this makes it possible to Reflector arrays of any length to form, which is advantageous if the arrangements must be adapted to certain lights. Furthermore, can Even slightly curved elements are used, resulting in a ring structure be assembled to form an annular reflector assembly.
- the separate elements according to the invention are preferably made of plastic and can be produced in particular by injection molding. Become two of such elements joined together, so can the juxtaposed End walls of the two elements together form a Rastquersteg, through which the reflector chambers are separated from each other.
- the end walls of the elements - seen in the direction of radiation - slightly outward be inclined so that one of two contiguous elements formed Rastquersteg is substantially V-shaped, as in the usual V-blades of light grids is the case.
- the assembled to the reflector assembly elements can by a separate holding element are held together, but preferably they have own connection means on which they are assembled.
- the connecting means can form tongue and groove joints, via which is a simple and quick assembly of the elements in the manner of a Modular system is made possible.
- the illustrated luminaire 1 is a recessed ceiling luminaire with a box-shaped lamp housing 2, which in the circular opening a blanket 3 is inserted.
- annular light source in shape a gas discharge lamp 5.
- the light emitted by this lamp 5 is intended for Bottom out are radiated, but only within certain Angular ranges to avoid glare.
- annular Reflector assembly 10 is provided, which seen in the emission in the is arranged substantially in front of the lamp 5.
- the restriction of the delivered Light rays on certain areas is on the one hand by the reflective Outer and inner walls 10a and 10b of the reflector assembly, but in particular arranged by a plurality of transversely thereto - shown schematically - Rastquerstegen 13.
- This Rastquerstege 13 divide the cross-sectionally U-shaped Reflector assembly 10 in a plurality of reflector chambers 12, which on its underside each form a light exit surface over which the light of the lamp. 5 is delivered. At its upper portion, the locking transverse webs 13 each have one Recess 11, which allows the lamp 5 within the upper area to arrange the reflector assembly 10.
- the shape and structure of the inner and outer walls 10a and 10b and the Rastquerstege 13 of the reflector assembly 10 is such that of the lamp. 5 emitted light only at certain angles the radiating the Can leave light chambers 12.
- the walls are each slightly laterally inclined, so that a lateral radiation is possible at smaller angles.
- the solution according to the invention is the reflector arrangement of separate Assemble elements, wherein the elements a reflector chamber or a Form group of reflector chambers. Corresponding elements are shown in FIGS. 2a and 2b.
- the element provided with the reference numeral 20 is box-shaped and has two side walls 21 and 22 and two end walls 23 and 24, the formed reflective at least on its inner side or with a reflective Layer are provided and together on its underside a light exit opening for a reflector chamber.
- the elements 20 are used to form an annular reflector arrangement form, which is why the side walls 21 and 22 are curved slightly arcuate and the outer side wall 23 has a larger radius of curvature than the opposite inner wall 21.
- connection means For joining the elements 20 are at this a plurality of connection means provided, via which the elements are joined together in a simple manner can.
- First connecting elements consist in a recess 25 a and a peg-shaped projection 25b, which at the two ends of a to the Light exit opening laterally adjacent bottom bar 25 are arranged.
- a cylindrical groove 26a At the opposite inner side of the element 20 is also a cylindrical groove 26a, which for locking with a columnar Projection 26b is provided.
- annular structure - as shown in Fig. 3 - are assembled to to form a total of an annular reflector assembly 10.
- Fig. 3 can be removed, meets the resulting reflector assembly 10 exactly the requirements of the lamp provided in Fig. 1 Reflector assembly.
- annular channel eleventh formed, in which the light source can be used.
- individual Reflector chambers 12 formed, which are separated by transverse webs 13 from each other. It is of particular importance that the reflector transverse webs 13 - as in Light grids desired - open at the top slightly V-shaped. This is achieved in that the Rastquerstege 13 through the two adjacent End walls 23 and 24 of two adjacent elements 20 are formed in Direction seen, are slightly inclined outwards and only at their Collide lower edges.
- each reflector chamber 12 of the reflector assembly 10 by a separate element 20 is formed.
- elements that have a Group of multiple reflector chambers 12, for example two or three Include reflector chambers are preferably provided.
- the reflector assembly 10 can thus in a simple manner be created that a variety of injection-molded Elements 20 is joined together.
- the through the connecting elements 25a, 25b and 26a, 26b produced tongue and groove connections provide this for a Reliable hold, so that a total of a stable arrangement is achieved.
- Effort for creating the reflector assembly 10 is significantly less than so far when joining many items according to the state of Technique was the case.
- An advantage of the inventive solution when creating straighter Reflector arrangements is that by the number of used Items in a simple way, the length of the reflector assembly to be created can be changed. There is thus a possibility in a simple way To provide reflector assemblies of different lengths without this one Additional effort would be required. It would also be possible to have more complex ones Form structures for reflector assemblies, provided the individual elements are shaped accordingly. For example, would be conceivable, S or snake-shaped To form reflector assemblies.
- the present invention provides a solution Reflector arrangements of even more complex forms in a simple and fast way too create.
- the formed with the help of composite elements Reflector assembly also has excellent optical properties, which is why they are also used in demanding lighting situations can.
