Definitions

  • the present invention relates to a lamp housing a street lighting with LEDs as a light source, consisting of a substantially rectangular, flat, metallic, monobloc housing with rear and front end faces and parallel longitudinal edge surfaces and a bottom of the housing with a hinged lid with a flat glass plate, below the LEDs, which are arranged in the housing in prefabricated groups, lie, and means are present, which limit the emission range of the LEDs to a desired light field.
  • Street lighting with LEDs as a light source have great advantages. On the one hand, the energy savings compared to street lighting with conventional light sources is enormous. The LEDs also have a much lower level of stray light and therefore significantly reduce light pollution.
  • the angle of emission of a light-emitting diode (LED) is substantially lower than the angle of emission of an incandescent lamp.
  • Light-emitting diodes for illumination purposes have a primary lens which already has a certain focus, and in particular those which which are used for street lighting, often also have a secondary lens, which is mounted on the primary lens made of plastic.
  • such a focusing plate is made of a relatively thin coated metal sheet.
  • the apertures forming apertures are referred to as punched, these openings can of course be achieved in other ways than by punching. In the present case, it will be preferable to create these openings by means of laser cutting. In this way, focusing plates can be produced quickly and individually. In this way, entire streets can be created in the 3D model, the place of installation of the candelabra can be varied, and for the optimal arrangement of a candelabra an image can be created, from which It can be seen how the desired light field has to be restricted or changed so that as little disturbing light as possible impairs the residents. From these models can then determine the corresponding focusing plates.
  • the lamp housing according to the invention are usually and preferably cast in one piece from metal or milled. In this case, it is preferable to integrally form the support elements on the lamp housing and provided with a threaded hole.
  • the replaceable focusing plate can be attached with high precision in the lamp housing with little effort. Since the distance between the focusing plate and the LEDs causes a further influence on the focusing, it is provided as a further preferred embodiment that in the lamp housing screw-connected spacers or spacers are provided as support elements. This way, the focusing plate can be mounted height-defined over the LEDs.
  • FIG. 1 shows a lamp housing according to the invention in the closed state with a view of the pivotable lid of the lamp housing.
  • the lamp housing as a whole is designated 1. It consists of the manufactured as a monobloc part 10 and a hinge 13 corresponding thereto pivotally movable cover 12.
  • the cover 12 is provided with a flat glass plate 14 in the entire area in which the multi-LED modules 19 are arranged.
  • the monoblock-type part 10 has a front end face 2 and a rear end face 3, and two parallel longitudinal edge faces 4. In the opened state, as in FIG FIG.
  • FIG. 3 is a partial section through the lamp housing 1 in the region of the light source shown in the form of multi-LED modules.
  • the zuberst recognizable planar glass plate 14 is directed in the assembled state of the lamp housing 1 on a candelabra, not shown, of course, at the lowest towards the street to be illuminated.
  • the monobloc-like part 10 of the lamp housing 1 is then at the top in the mounted state, and here the heat radiating fins 8 are arranged.
  • the partial section shown here runs through such a heat radiating rib 8.
  • the receiving space 6 is located on the monoblock-like part 10 of the lamp housing 1, an insulating support plate 7.
  • the multi-LED modules 19 are arranged. These multi-LED modules 19 are prefabricated groups of LEDs.
  • These multi-LED modules are arranged in a tight array in three fields A, B, C. Between each two adjacent fields there is a strip-like distance. The LEDs themselves are labeled 24. Distanced over the multi-LED modules 19, the focusing plate 20 is held. The focusing plate 20 rests on support element 25.
  • These support elements 25 are realized in the example shown here as sleeves which rest on the insulating support plate 7, and fixing screws 26 pass through the support member 25 and the insulating support plate 7 and engage in threaded holes 27 in the monoblock part 10 of the lamp housing 1 a.
  • the support plate 7, which can be both electrically and thermally insulating, is thus stabilized by these screws connected to the monoblock part 10 of the lamp housing 1.
  • Such an insulating support plate can be made for example of a hard plastic or foam glass.
  • the support plate can also consist of a material with good thermal conductivity to conduct the waste heat of the LEDs in the monoblock part 10 of the lamp housing 1, via which the heat can be dissipated by the heat radiating ribs 8 to the environment.
  • materials for example ceramics or materials based on silicone rubber.
  • Such plates are offered as so-called réelleleitpads on the market.
  • FIG. 4 are now the invention particularly essential focusing plates 20 shown by themselves.
  • These plates have a rectangular basic shape and have two relatively wide carrier webs 21.
  • These carrier webs have a width which corresponds approximately to the width of the LED-free areas between the spaced apart fields A, B, C, which are multi-LED modules are occupied.
  • Between the carrier webs 21 several apertures forming punched 30 are formed. These apertures forming punched 30 are separated from each other by aperture webs 23.
  • the apertures forming punching are normally parallel slits, as the embodiments according to the FIGS. 4a and 4b demonstrate.
  • Each slot-shaped cutout 30 corresponds to a serially arranged plurality of LEDs of adjacent multi-LED modules.
  • the slot-shaped cut-outs extend substantially in the direction of the road to be illuminated.
  • the width of the punched holes are all shown in the same width, this is by no means required. Rather, it may happen that in particular the apertures 30 forming the lateral fields A and C are provided with narrower apertures forming punching as those punched out in the field of middle field B are arranged.
  • the shows Figure 4c Yet another variant of a focusing plate 20, in which the apertures forming the apertures are configured instead of virtually over the entire width of the focusing plate 20 extending punching 30 with rows of hole-shaped punched-out.
  • each hole can be assigned to one LED, or several holes can be assigned to a single light-emitting diode.
  • the luminous field to be formed is not only determined by the size of the apertures forming apertures 30, but also by the distance of the focusing plate 20 to the LEDs. If the focusing plate 20 is further away from the LEDs, the beam angle is cut more sharply than if the focusing plate is located very close to the LEDs.
  • the emission angle can be additionally changed by the central longitudinal axis of the diaphragm forming punch is not located exactly centered over the corresponding row of LEDs. This can be varied, for example, by the screw holes 22 in the carrier webs 21 are not arranged exactly centered.
  • the focusing plates 20 used according to the invention can be manufactured individually with little effort for each lighting situation.
  • the course of the street can be considered, as well as the proximity of a building frontage from the roadside. So can be used for streets and alleys also in Insert an old city lamp housing, which are equipped with LEDs, regardless of whether the LEDs used have a secondary lens or not. All lamp housings can thus always equip the same with multi-LED modules of the same design, and only by the used focusing plate 20 can be achieved to achieve the luminous field.
  • the blanks forming punched-30 may also be designed as a slot-shaped as well as punch-shaped apertures 30 forming.
