Definitions

  • the invention relates to a lamp with a lamp associated with one of these Reflector for generating a light beam distributed around a main radiation direction and a transparent lens assembly for distributing a part of the one of Lamp outgoing light.
  • downlights that is Ceiling lights integrated in the ceiling, usually with halogen lamps, reflectors or to arrange a lens arrangement.
  • Downlights usually generate a very steep downward light distribution, wherein the main radiation direction is substantially vertical. Not only high Horizonta - sondem also vertical illuminance to achieve (low would be a Ratio of at least 3: 1, better 3: 2), the light should also be very flat or have horizontally emergent light rays. But these rays of light cause In general, a strong glare, which is undesirable.
  • the light intensity thus does not start from one point of the visible light exit surface, but of very many and very small arranged at intervals to each other Points of light (preferably less than 2 x 2 mm) of the individual lenses. That's it possible, even shallow emerging light rays with a high vertical Illuminance and at the same time to avoid glare. you thus achieves ceiling and wall illumination also for downlights.
  • the disadvantage of the described prior art is that the Abblendwinkel the Luminaire is specified by the respective vertical extension of the lens body.
  • the object of the invention is to improve a generic lamp in the manner that a viewer even with Linsenkörpem with limited vertical extent only can look directly into the lamp at very steep angles, causing glare is avoided for large angular ranges.
  • the lens body substantially along the main radiation direction are distributed and, preferably in each case, the Main radiation direction, preferably annular, surrounded.
  • each other arranged lens body in particular annular lens body, with each other stacked provided.
  • This can be an even finingliederere Lichttechnikzerlegung make.
  • the glare is further reduced or the Vertical illuminance increased.
  • Through the stack of superimposed Lensenkörpem is also the direct insight into the lamp only under very steep Angle possible.
  • the lenses or lens body may be arranged and dimensioned so that the the lamp associated (main) reflector a large part of the lamp luminous flux with the help of a convergent radiation principle according to Lighting task distributed in a defined solid angle down, namely such that most of the lamplight passing the lens material passes through the lens Inside of the annular lens body exits freely.
  • the remaining radiation of the lamp, which is no longer caught by this (main) reflector, namely the so-called direct radiation component applies to the preferred embodiment superimposed annular lens body, the light by refraction so disassemble and divert that the desired Lichtigezerlegung with high Vertical illuminance is achieved.
  • the number of lenses should be greater than 30, preferably even greater than 100, his.
  • the lens effect can during the annular lens body come about by the fact that this on its inside has a plurality of concave recesses, each of these indentations a own lens surface forms.
  • the luminaire shown in FIG. 1 is a so-called downlight, which is installed in a ceiling 11.
  • the luminaire has in a luminaire housing. 1 a reflector 2 and a lamp 3.
  • the reflector 2 generates as Reflective radiation component of the light a bundle of light that is vertical to here directed downward main radiation direction 4 is distributed (see also Fig. 4).
  • a lens arrangement 5 is provided according to the invention has a plurality of lenses 6 distributed around the main radiation direction.
  • Each of these one-piece lens body for example made of glass or transparent plastic is around the main radiation direction 4 around ring-shaped.
  • the individual lenses 6 are formed by the fact that the lens body on his, the Main radiation direction 4 facing inside a plurality of concave indentations 6a, each of these indentations having its own lens surface Diffuser lens forms (see Fig. 3).
  • the lens body 7 On its outer side, the lens body 7 is in each case cylindrical, which is what it is allowed to guide a glass cylinder 8 as a dust cover just, with this preferably glued dust-tight at the points 9 with the bottom lens body 7 is.
  • a horizontal glass plate 10 which also with the the lowest ring is glued
  • the mechanical holding elements for the lens body are not shown in the figures. It may be, for example, thin Bars or ropes act. But it can also transparent retaining elements be provided.
  • the top surfaces 7a and bottom surfaces 7b of each lens body are each parts of a conical surface, the imaginary cone pointing upwards with its tip to the lamp-reflector combination 2, 3.
  • the reflection radiation component reflected by the reflector 2 emerges from the luminaire as an initially convergent and then divergent bundle of light rays 12 (reflection radiation component), namely substantially unhindered by the lens arrangement 5, that is to say simply between the lens-shaped lens bodies 7.
  • a portion of the direct radiation portion of the lamp 3, which does not fall on the reflector 2 reaches the lenses of the lens body and is deflected by these flat to the outside.
  • FIG. 4 A part of the thus deflected beam path is designated in FIG. 4 with 13. What is essential is the inventive effect of breaking the lamp into individual points of light through the many zirkumverial distributed lenses 6, which make it possible to have flat light rays, without having to accept a dazzling effect in purchasing.
  • the invention is of course not limited to the illustrated embodiment,
  • the structure and the number of lens body may vary.
  • individual separate lenses are possible. It is essential - how already mentioned - the light point decomposition effect of the many lenses that allows to have flat horizontal rays without glare.
