Definitions

  • the invention relates to a polygonal reflector for a lighting device, such as an incandescent lamp or the like.
  • a polygonal reflector for an illuminant consisting of a reflector element arrangement with several individual, adjacent reflector elements.
  • Polygonal reflectors for example - as from DE 41 36 251 A1 known - can be designed square to achieve certain lighting effects needed.
  • a polygonal Reflector comprises a reflector element arrangement, which consists of several individual, adjacent reflector elements. With these Reflector elements can be polished, chrome-plated or even superficial satined sheet metal pieces or aluminum pieces whose The surface is polished and then anodized, act on their Edges are connected to form the reflector. The have individual reflector elements of this reflector element arrangement alternately molded to connect them in the area of their side edges Tabs or push-through openings.
  • Two contiguous Reflector elements are now by inserting the tabs of the a reflector element in the corresponding openings of the other reflector element and then bending the tabs attached to each other.
  • the reflector elements are usually with a Curvature provided to the desired lighting requirements to suffice.
  • a bend of such a fastening tab for Attaching two adjacent reflector elements leads however, that the predetermined in this area of the reflector element Curvature is straightened so that this part of the reflector elements formed reflector by a bright ring of light or by a similar irregularity, which in turn is perceived as disturbing.
  • a round reflector has become known from US Pat. No. 4,789,921 consists of a single reflector element, which is in a support body is held.
  • the reflector element is disc-shaped before it is installed trained and is formed by the support body in a truncated cone Arrangement kept. It can be provided that the reflector element on the support body by means of an adhesive or by means of a Deadlock can be kept.
  • this arrangement are polygonal Reflectors, especially when the individual reflector elements should be curved, not feasible.
  • a polygonal reflector has become known from US Pat. No. 5,568,680. That of a reflector element arrangement with several individual, adjacent There are reflector elements, the reflector being a support body includes.
  • the invention lies on the basis of this prior art discussed therefore based on the task of a polygon mentioned at the beginning To further develop the reflector in such a way that it does more than just the lighting Requirements are sufficient, but can also be produced with simple means is.
  • the reflector according to the invention consists of a support body and several number of reflector elements corresponding to the number of reflector sides.
  • the support body serves both to hold the attached reflector elements and for shaping the individual Reflector elements with respect to the predetermined curvature that the Should have reflector.
  • the individual reflector elements flexible, for example, sheet metal pieces that are attached to you brought into their intended curvature on the support body become.
  • For attaching the reflector elements on the support body points a holding pocket in the area of each reflector edge to be trained in which a reflector element engages with its lateral edge area.
  • To form a reflector inner edge on this in the holding pocket engaging reflector element is the adjacent reflector element with its lateral face on the reflection surface of the arranged in the holding pockets inserted reflector adjacent.
  • the reflector elements are shaping with regard to their curvature Support body attached by an adhesive connection.
  • adhesive or adhesive stands for all those connections between the support body and a reflector element, whereby the two parts to be joined by adhesion and / or cohesion and / or other physical / chemical processes connected to each other are.
  • the support body forms a holding base for the reflector elements, which is designed according to the intended reflector curvature is.
  • the connected to the support body by an adhesive connection Then reflector elements have the same curvature as the support body itself.
  • the support body can, for example, as a complete reflector housing or be designed as a reflector frame constructed like a framework, with the latter embodiment of the support body sufficient contact surfaces has to the reflector elements in the desired shape in your Bring attachment and to provide sufficient attachment reason.
  • the reflector arrangement can be circumferential alternately arranged sequence of with their two side Edge areas in reflector elements and holding pockets such reflector elements exist, which are attached to the support body with its two lateral end faces on the reflection surfaces of the limit adjacent reflection elements.
  • a shape of the with their two lateral edge areas, each engaging in a holding pocket Reflector elements are made by the grooves Holders themselves that follow the curvature of the body.
  • Shape of these reflector elements is an adhesive connection with the Carrying body is generally not necessary. However, gluing makes sense to prevent this reflector element from being pulled out.
  • On reflector element arranged between two such reflector elements thus borders on the reflection surfaces with its two lateral end faces the reflector elements held in the holding pockets. This reflector element is in its intended by an adhesive Curvature held attached to the support body.
  • a reflector 1 for an illuminant consists of a support body 2 and a reflector element arrangement 3.
  • the reflector element arrangement 3 is made up of individual adjoining reflector elements 4, 5 formed.
  • the reflector elements 4, 5 are pieces of aluminum sheet whose surface visible in the figures is highly polished.
  • the supporting body 2 serves as a shape-retaining base for the individual reflector elements 4, 5, so that this in the reflector 1 provided for the reflector curvature attached to the support body 2 are held.
  • the reflector 1 shown in FIG. 1 is a square reflector, the reflector element arrangement 3 of which is composed of four reflector elements, namely two reflector elements 4 and two reflector elements 5.
  • the support body 2 is designed as a reflector housing completely surrounding the reflector arrangement 3.
  • holding pockets H are assigned to the support body, which are open towards the reflector element arrangement 3.
  • the holding pockets H are designed as grooves and, as can be seen from FIG. 2 , extend in accordance with the curvature of the carrying body 2.
  • the holding pockets H of the carrying body 2 shown in the figures are arranged such that one reflector element 4 with its two lateral edge regions in two opposite holding pockets H can be used.
  • such a reflector element 4 is trapezoidal.
  • the shape of the reflector element inserted into the holding pockets H is already fixed by the groove-shaped holding pockets H.
  • an adhesive K is introduced between these two parts 2, 4.
  • the further reflector element opposite the reflector element 4 4 is inserted in a corresponding manner in the support body 2.
  • the reflector elements 5 used.
  • the reflector elements 5 are as shown in FIG. 4 Top view recognizable, approximately trapezoidal, with this however in contrast to the reflector elements 4 curved lateral Have contours.
  • the curvature of the side surfaces corresponds to this of the reflector elements 5 of the curvature of the support body 2 or Curvature in which the reflector elements 4 are held by the holding pockets H. are.
  • the reflector elements 5 are through the use of an adhesive K attached to the inside of the support body 2.
  • the reflector elements 5 border with their lateral end faces directly to the reflection surfaces of the reflector elements 4.
  • the Formation of the inner reflector edges R is therefore solely of the dimensional accuracy depending on the curvature of the side surfaces of the reflector elements 5.
  • the inner edge R of the reflector formed in this way is also sufficient high lighting requirements.
  • the edges pointing outwards of the reflector elements 5 can reduce the reflection surfaces of the reflector elements 4 contacting lateral end faces be chamfered.
  • the ring 7 can accommodate a lower one Ring cover serve as cladding.
  • such a reflector not only meets high lighting requirements, but also can also be produced with simple means.
  • such a reflector can also have a rectangular shape, for example, be hexagonal or octagonal.
