Definitions

  • the invention relates to an outdoor lamp according to the preamble of claim 1.
  • a lamp is z. B. from the DE 198 34 195 A1 known.
  • Outdoor luminaires with a reflector made up of facets have generally proven useful in street lighting and the like, especially since they provide a way of defining the areas to be illuminated more precisely and individually than with conventional techniques.
  • dark stripes are observed on the surfaces to be illuminated and / or on walls which adjoin the surface to be illuminated.
  • These stripes are particularly noticeable in road tunnels and on road surfaces with a high mirror factor. This streaking occurs in particular in the near field area, for example at a distance of 3 m to 6 m from the luminaire.
  • Such near-field effects can not be determined by light intensity distribution measurements during production and construction and only appear as illuminance irregularities directly under the luminaire or on the walls.
  • CA 2 247 233 A1 discloses a luminaire with a parabolic reflector and a Kocnpaktleuchtstoffrschreibe arranged therein.
  • this document proposes to divide the reflector in the circumferential direction in segments of 90 °. The reflector surface of two segments is highly distorted, while the reflector surface of the other two segments is dotted to cause light scattering.
  • EP 0 732 538 A2 relates to a luminous element with a faceted reflector.
  • the reflector facets are alternately either smooth or provided with a light-diffusing structure.
  • EP 0 790 115 A2 relates to a method for producing a reflector for a vehicle headlight.
  • the reflector is manufactured by injection molding and has a surface quality, which allows a subsequent metallization without a further intermediate layer.

  • a road or a tunnel As a road or a tunnel, according to claim 1.
  • At least one first coherent one of a side wall of the reflector, Light at least partially scattering area and at least a second continuous, light directed reflecting area of the reflector are provided.
  • the light at least partially scattering region of the reflector may reflect a part of the incident light directed and scatter a further portion of the light.
  • a surface structure having portions having a smooth surface reflecting light is formed in the corresponding area, and irregularly shaped surface portions reflecting the light incident from a certain direction due to the irregularity in different directions.
  • the irregularly shaped surface sections taken by themselves, can be quite reflective. However, these surface portions are so small as compared to the total area of the subject area, or possibly also compared to the directionally reflective portions of this area, that the proportion of light reflected from such an irregular structure in a particular direction is small compared to the whole reflected amount of light is.
  • the substantially directionally reflective areas of the reflector are usually formed with a smooth surface. According to the invention, however, these areas can also scatter a small part of the reflected light, but this proportion is smaller, usually much smaller than the proportion that is reflected by the first area scattering.
  • the first and second regions have at least those dimensions at which the light at least partially scattering surfaces appear uniform, e.g. uniformly matt or uniform (not necessarily regular) structured. These dimensions are greater than the distance at which the surface structure varies or shows irregularities. If the reflector has facets, the first and second regions are preferably each at least as large as one facet.
  • the invention can provide that a region or that region of the reflector, which light at least partially reflected in the vicinity of the lamp, light is formed at least partially scattering.

  • At least one reflector region which reflects light up to an angle of 0 ° to 40 ° with respect to a perpendicular to the light exit surface of the reflector, may be at least partially light-scattering. While the range of angles given above encompasses those angles which result in most practical applications, depending on the lighting task to be solved, e.g. B. depending on how high the lamp is mounted above the ground, at which distance from the light illuminated surfaces, such as house or tunnel walls, this critical angle can be selected larger.
  • the invention may also provide that at least one reflector region, which reflects light up to an angle of 0 ° to 40 °, relative to the vertical in space, light is formed at least partially scattering.
  • the reflector is at least partially constructed of reflector strips of individual facets, which extend, starting from the light exit opening, in a direction perpendicular to this, wherein at least one contiguous group of facets, which facets of one or more strips .
  • Light is at least partially scattering formed and / or at least one contiguous group of facets, which facets of one or more reflector strips, is formed substantially directionally reflective.
  • two or more of the aforementioned groups may also be provided.
  • facets which reflect in the vicinity of the lamp, light may be formed at least partially scattering.
  • the reflector has a roof section and reflective side walls, wherein at least one region of the side walls adjoining the roof section is formed at least partially scattering light.
  • the roof section may also be wholly or partially subdivided light-scattering also.
  • the invention may also provide that a directly adjacent to the light exit opening portion of the reflector is designed to be reflective.
  • the invention may also provide that the reflector and the lamp of the luminaire are designed and arranged such that the spatial region in which light is reflected by the reflector is substantially larger in a plane parallel to the light exit surface along a first axis than along one vertical second axis, wherein at least one reflector region which reflects light in a direction substantially parallel to the second axis, at least partially scattering light, z. B. is formed matte. It can be provided in particular that at least one reflector region which reflects light substantially in a direction perpendicular to the longitudinal axis of the illuminated terrain section, at least partially formed light scattering.
  • the invention may quite well provide that at least one or more of one or more further reflector regions which reflect light into an angular range about said second axis in the aforesaid plane and about the direction perpendicular to the longitudinal direction of the illuminated terrain section are formed scattering.
  • This angular range can z. B. in a range of ⁇ 10 ° to ⁇ 80 °. If the terrain section to be illuminated is narrow and surrounded by walls, for example in narrow tunnels, this angular range can be very large, for example in the case of narrow tunnels. 80 °, while when the area to be illuminated is wider, it will generally be smaller.
  • the luminaire according to the invention can be inclined to the horizontal, so that the light exit surface is not parallel to the horizontal.
  • the above-mentioned relations and dimensions, in particular the specified angular ranges, according to an embodiment of the invention with respect to the horizontal plane, instead of with respect to a plane parallel to the light exit surface, may be provided.
  • Such a design of the reflector is advantageous if, in the direction in which this reflector region reflects, there is a wall on which a striped pattern of the reflector can emerge.
  • the invention may provide that reflector regions which reflect light in two opposite directions, each substantially parallel to said second axis, are at least partially diffused.
  • Such an embodiment is particularly advantageous if there are walls in the direction of the second axis on both sides of the lamp, as z. B. in road tunnels is the case.
  • the light-scattering regions of the reflector are provided with a light that at least partially diffuses the light.
  • Such a structure may be, for example, a sandblast structure, a hammer blow structure, or a leather grain structure.
  • a leather grain structure can provide a structure of line-like elevations, in particular on a surface which is in itself smooth. which are irregular in terms of both their course and height. These elevations form narrow strips which run through the surface and whose width is relatively small in relation to the area in question, for. B. to the area of a facet.
  • the surface of the increase can be quite self-reflective. However, since their width is very narrow, the proportion of reflected light is relatively small. Accordingly, since the course of this surface is irregular, small amounts of light are irregularly reflected in different directions, thereby resulting in a light-scattering effect.
  • the invention can also provide that the surface of the corresponding area is a vault structure, as for example by a method according to DE 43 11 978 C1 . DE 44 01 974 A1 . DE 44 37 986 A1 . DE 195 12 533 A1 . DE 196 11 478 A1 . DE 196 34 244 A1 or DE 196 51 937 A1
  • a structure does not necessarily have to be made by a method according to any of the above references, but has only the same properties as a structure produced by this method.
  • the reflector is made of plastic, alternative methods of producing identical or similar structures may be used.
  • the structure may also be designed in such a way that a part of the light incident on the corresponding area is reflected in a directed manner and a further part of the light incident on the area is scattered, whereby the proportion of the directed light can definitely predominate. Due to the light scattering share is achieved that the space area in the corresponding reflector area, z. B. one or more facets, reflected, not sharply defined, but rather has a smeared transition, d. H. an edge region in which the light intensity of the light reflected by the facet does not fall sharply, but drops off with a more or less extended edge.
  • areas with different light at least partially scattering structures may be provided in the reflector.
  • the light-scattering areas of the reflector are not absolutely necessary to provide the light-scattering areas of the reflector with a light-scattering structure. It can also be provided that these areas of the Reflectors are provided with a light at least partially scattering coating, paint or the like.
  • the invention also provides a method of manufacturing a reflector for a luminaire as described above, wherein the reflector is formed by a molding tool characterized in that the molding tool is provided in areas corresponding to light at least partially diffusing areas of the reflector the negative of a light is at least partially scattering structure provided.
  • the reflector is molded from plastic.
  • the molding tool is polished in areas which correspond to reflectively directed areas of the reflector.
  • the smooth areas of the mold lead accordingly to smooth surfaces of the reflector, while rough surfaces of the mold lead to a rough and thus light-scattering surface of the reflector.
  • the mold is polished even in areas where a light-scattering structure is provided, so that the surfaces of the structure are locally smooth and thus specularly reflective. The light scattering effect results in these cases by the macroscopically irregular course of the surface.
  • the invention may also provide that the inner wall of the reflector is provided with a reflective coating after the molding process.
  • a part of the mold is provided with a structure which corresponds to the negative of a light at least partially scattering structure and another part of the mold is completely smooth, so that results in the molding process, a smooth surface of the reflector, results after coating with a reflective material automatically in the areas where a structure already exists, a light scattering effect, while in those areas where the mold completely was smooth and, accordingly, the reflector wall is smooth, resulting in a directionally reflective area.
  • the invention may also provide that the reflector is conventionally formed from sheet metal that has been patterned prior to molding with a light-scattering structure. If the reflector made of Belch, a step shape between the individual reflector strips can be difficult to realize, so that it can also be provided that between two directly adjacent reflector strip in the direction perpendicular to the reflective surface remains a space not filled by material.
  • the reflector pot is made of sheet metal, it may be useful to construct the reflector pot from several individual parts, for example, a first part, which contains the structured facets and a second part, which contains the non-structured facets.
  • the invention is based on the surprising finding that the above-described streakiness can be generally solved without significant losses for the efficiency of the luminaire and for the luminous intensity distribution, that a part of the reflector light is at least partially scattering and formed another part of the reflector high gloss is.
  • the high-gloss areas or facets which preferably lie in the region of the light exit opening or adjacent to it, ensure optimum and targeted light distribution on the section to be illuminated, e.g. a road surface, and thus for the optimum lighting quality, which manifests itself in the case of street lighting in a high luminance of the road, a high luminance uniformity of the road and in glare limitation of the lamp with the lowest possible number of lights and low energy consumption of the individual lights.
  • the matt reflector areas ensure targeted light scattering and light insulation.
  • Fig. 1 shows a schematic plan view of a reflector of a lamp according to the invention.
  • Fig. 1 shows a generally designated 1 reflector for a street lamp according to the invention, the reflective inner surface has the shape of an oval, which at the two End faces is cut or cut.
  • Fig. 1 shows the view of the light exit opening of this reflector.
  • a lamp (not shown) is used, the supply line and socket are inserted through the recess 5 on the designated A front side of the reflector in this.
  • the reflector 1 has a roof portion 7, which has a regular structure of pyramidal elevations, which are indicated in the drawing, and side walls 9 1 , 9 2 and 9 3 , which extend between the light exit opening and this roof section.
  • the side walls 9 1 and 9 2 are constructed of reflector strips 11 which extend between the light exit opening and the roof portion 7 and are arranged adjacent to each other along the circumference of the reflector 1, so that the entire periphery of the reflector is formed by such reflector strips.
  • the transition between the individual reflector strips 11 is not necessarily continuous, but can be step-shaped, corresponding to the different orientation of the facets in adjacent reflector strips. Even within the reflector strips, the transition between the individual facets, which are each individually oriented, need not necessarily be continuous. Successive facets of a strip may also be slightly offset from each other.
  • the reflector strips themselves are in turn each constructed from a plurality of reflector facets 13 which are arranged successively in the direction from the light exit opening to the roof section 7.
  • the sidewall 9 3 is formed by a single region of specularly reflective reflector facets 14 extending across the entire width of this sidewall.
  • Each of these reflector facets 13 and 14 substantially reflects light from the lamp within a certain angular range.
  • the entirety of the reflector facets determines the luminous intensity distribution curve of the luminaire or the illuminance or the luminance distribution on the terrain section to be illuminated.
  • the illuminance or the luminance distribution can be built up from the individual reflections of the individual facets and thus be designed in a wide range.
  • Reflector facets located near the light exit aperture tend to reflect into a far region of the luminaire or at relatively shallow angles to the light exit aperture, while facets which are closer to the roof portion 7 reflect into the near zone of the luminaire.
  • the reflector facets on the two end faces A and B reflect in a direction transverse or oblique to the road direction
  • the lamp shown is the roof section 7 with the pyramidal elevations matte or diffuse reflective formed.
  • the in Fig. 1 hatched reflector facets formed light scattering.
  • the non-hatched facets have a directionally reflective design. It can be seen that in a region 15 of facets which adjoins the light exit opening and extends over the entire circumference of the reflector, the facets are reflective. However, the width of this area varies. Near the face A, this area is narrow, while it is wider in the middle of the side faces C and D. In the area of the long sides C and D reflect the matte reflector facets on the floor in the vicinity of the lamp.
  • the directionally or specularly reflective reflector facets reflect into the femoral region. It has been found that by the light scattering training of the corresponding reflector facets in the vicinity of the streakiness z. B. is lifted on the ground or adjacent tunnel walls. In contrast, a light-scattering design of the facets in the area near the light exit opening is not necessary because there the problem of banding does not occur and seeks in the remote area as directed radiation to illuminate areas at long distances from the lamp.
  • the region of the light at least partially scattering facets extends closer to the light exit opening on the front side A than on the sides C and D, has two reasons.
  • the emission range of the luminaire along the axis E is substantially smaller than along the axis F. Accordingly, more facets also reflect on the side A on the ground in the vicinity of the luminaire.
  • Light is also imparted to these walls by such facets, which reflect light only at a relatively shallow angle to the light exit opening, which would normally be attributable to the remote emission area, if the light reflected by these facets were incident on the floor.
  • the light already hits above the floor on a wall at a distance from the lamp, which may well be in the vicinity, ie at a distance of about 3 m to 6 m, so that form stripes on the walls. Therefore, in the region A, also those facets which only reflect light at a shallow angle to the light exit opening are light-scattering in order to avoid these fringe effects on walls.
  • the luminaire according to the invention can, with regard to the reflector structure in particular as in the DE 198 34 195 A1 be described, reference is made to the reference and with respect to the formation of the reflector and the lamp in general by way of reference forms an integral part of this description. Referring to Figs. 2 and 3 of this reference, the area of directionally reflective facets around the light exit aperture in the reflector strip A would be relatively narrow, then increase in areas B, C, D, E and F and then in areas G and H again lose weight.
  • the facets on the side 9 3 are all directed or mirror-inverted. Such a design is useful if there are no illuminated areas in the vicinity of the lamp on the side opposite the side B. However, if such surfaces are present in the vicinity of the front side B, as is the case for example in tunnels, and the side 9 3 may be formed similar to the region of the side A, such that, starting from the roof portion 7, a or a plurality of successive facets 14 light are formed at least partially scattering, where appropriate, the entire region of the side wall 9 3 may be formed light scattering.
  • the reflector shown above was integrally formed, it may also be formed by a plurality of parts.
  • the side wall 9 3 is designed as an insert, which, depending on the desired lighting task, can be exchanged for a light-scattering use.
  • the reflector is arranged so that the specularly reflective wall 9 3 can be covered by an insert which is wholly or partially formed light scattering.
  • the in Fig. 1 shown reflector is received in accordance with an embodiment of the invention in a lamp housing or forms such a lamp housing.
  • the invention may also provide that two or more such reflectors are accommodated in a luminaire housing.
  • Two or more reflectors, as in Fig. 1 can also be formed from one piece and connected to each other via the edge regions 17.
