Definitions

  • the invention relates to an attachment for free-radiating miniature reflectors that contain a lamp.
  • the miniature reflector and the lamp form a fixed or unit.
  • the reflector diameter is a few centimeters.
  • the illuminant is usually a low-voltage halogen lamp.
  • the miniature reflector has a base with connection elements for a lamp holder, for example in the form of plug contacts.
  • Miniature reflectors of the type described are used for living room lighting and in the commercial sector for illuminating goods displays, shop windows and the like, also as so-called free spotlights, that is to say without an exterior housing.
  • the header to which the invention relates is intended to restrict the emission of light, to avoid glare, to hide certain areas for design reasons, and the like.
  • Light directing attachments for lights are known.
  • work is carried out with attachment holders into which filter disks, lenses, gratings, foils, masks, grids, flaps and screens can be inserted.
  • the known attachment holders can be attached to luminaire housings and are designed in several parts, with complex construction. As part of the known measures, they are generally only used for professional or semi-professional lights.
  • the invention has for its object to provide an attachment for free-radiating miniature reflectors that can be attached directly to the miniature reflector and can be easily replaced.
  • the object of the invention and solution to this problem is an intention, which is characterized by
  • At least one light-guiding element molded onto the support element for influencing the light emission from the miniature reflector
  • the attachment element consists of a temperature-resistant, non-elastic, but flexible material and is held in a form-fitting manner by the clamping elements on the edge of the reflector. All functional elements (retaining clips, hinges, slats, flaps) are made from the component itself formed.
  • the attachment element is preferably manufactured as a stamped and bent part from a stainless spring steel sheet and is provided with a matt black surface.
  • the attachment element according to the invention can be manufactured with a very low weight, so that the usual connections between the miniature reflector and the lamp holder can easily accommodate the additional weight.
  • the weight of the front element is regularly smaller than the weight of the reflector with illuminant.
  • the attachment element according to the invention is inexpensive, reliable and easy to use. It can be attached and removed without tools without prior knowledge. Cleaning is easy. The low effort has a positive effect both in terms of the purchase as well as any damage or loss.
  • the attachment element according to the invention is also suitable for effortless retrofitting in free-radiating miniature reflectors.
  • the support element is a support ring, on which angularly bent clamping elements are formed.
  • the clamping elements are expediently designed as brackets which enclose a ring segment of the reflector edge. A particularly simple and safe latching results in particular if the brackets are curved in an arc and close to their connecting webs have projections directed towards the underside of the reflector edge.
  • the invention teaches that at least two light flaps are connected to the support ring by bend-deformable webs or that light guide lamellae are connected to the support ring, the light guide lamellae being connected to the support ring by webs and bent at right angles to the support surface.
  • Two or more light deflection slats arranged in parallel can be provided.
  • at least three light-guiding slats can also be provided in a radial arrangement, the light-guiding slats being integrally connected to one another in the center, for example by a connecting disk.
  • a particularly preferred embodiment of the invention is characterized in that two light flaps are arranged on opposite circumferential sections of the support ring, that the clamping elements are positioned at a right angle to the circumference of the support ring and that the light flaps each have two bend-deformable webs are connected to the support ring, the distance between the webs being greater than the width of the clamping elements and thereby a further attachment element can be plugged on, the clamping elements of identical design to the first attachment element can be inserted into the free space between the webs and grasp the reflector edge.
  • attachment elements with light flaps can be combined with one another, as well as attachment elements with light flaps and light deflection slats.
  • An alternative embodiment of the invention provides light-guiding lamellae which are connected to one another in one piece by at least one web and rest on the reflector edge with their lamella end on the outside of the reflector, holding lugs being formed on the lamella ends, which reach behind the reflector edge.
  • 3 shows an attachment with parallel light deflection slats, 4 the combination of two attachments, each with two light flaps, attached to a miniature reflector,
  • FIG. 5 shows the combination of an attachment with light deflecting lamellae and an attachment with side light flaps
  • FIG. 6 shows another design of an attachment for a free-radiating miniature reflector.
  • the figures show light directing attachments, each of which is attached to a miniature reflector 1 with illuminant 2, integrated cover plate 3 and edge 4. They have a support element 5 resting on the reflector edge 4 of the miniature reflector 1, at least two clamping elements 6 molded onto the support element 5, which grip the reflector edge 4, and at least one light-guiding element 7, 8 molded onto the support element 5 for influencing the light exit from the mini reflector 1 .
  • the support element 5, the clamping elements 6 and the light directing elements 7, 8 always form a one-piece attachment element 9 made from one piece.
  • the attachment elements 9 are one-piece stamped and bent parts, which in the embodiment are made of a stainless spring steel sheet and one have a matt black surface.
  • the support element 5 is a support ring on the angularly bent clamping elements 6 are formed.
  • the clamping elements 6 are designed as brackets, each of which grips a ring segment of the reflector edge 4 and thereby hold the attachment element 9 positively on the reflector edge 4. It can also be seen that the brackets are curved in an arc and have projections 10 directed towards the underside of the reflector edge 4 near their connecting webs.
  • the light directing elements can be designed differently.
  • 1 shows an embodiment with two lateral light flaps 7 which are connected to the support ring 5 by webs 11.
  • the webs 11 are bendable and fulfill the function of bending hinges.
  • the light-guiding blades 8 are connected to the support ring 5 by webs and bent at right angles to the support surface.
  • three or more light-guiding lamellae can be provided in a radial arrangement, the light-guiding lamellae being integrally connected to one another in the center by a connecting disk 12 (FIG. 2).
  • 3 shows an embodiment with light deflection slats 8 arranged in parallel, which in this respect form a parallel grid.
  • attachment elements 9 with lateral light flaps can be combined with one another and also with an attachment element which has light deflection slats 8.
  • the combination of two attachment elements 9 is possible if the distance between the webs 11 of the light flap 7 is larger than the width of the clamping elements 6. This allows a further attachment to be plugged on by inserting the clamping elements 6 of this attachment into the space between the webs 11 and then grasping the reflector edge 4.
  • the attachment element 9 has light-guiding slats 8 which are integrally formed by at least one web, e.g. B. in the form of a connecting disc 12, are connected to each other and rest with their reflector outside lamella end on the reflector edge.
  • the lamella ends form the support element 5.
  • Retaining lugs 13 are formed on the lamella ends as clamping elements, which grip behind the reflector edge 4 and hold the attachment element 9 in a form-fitting manner on the reflector edge 4.
