Definitions

  • the invention relates to a reflection device consisting of a planar reflection element for reflecting, at least a light source of emitted light rays.
  • Such reflection devices are used in particular in Lighting devices, in particular for quality control processes used.
  • Lighting devices put together, in which the light one Light source through deflection reflectors for irradiating one of the light sources distant reflection surface is deflected.
  • the light source, the deflecting reflectors and the reflective surface optimally to each other aligned and the deflecting reflectors and especially the reflective surface can be set exactly.
  • Such installations are very complex and are arranged in the area of the production lines as a fixed installation.
  • a disadvantage of the known reflection devices is that they are limited in their adjustability, so that difficult errors on certain surfaces are made practically invisible or only by specially trained personnel or using additional Measures can be recognized.
  • the object of the invention is to improve a reflection device of the generic type in such a way that, with economical manufacture and assembly, the generation of light is made possible, which also makes difficult errors more easily visible, and / or which also permits a multi-surface inspection of three-dimensional elements.
  • Difficult errors in the sense of the present invention also include Scratches, paint defects, etc. also small three-dimensional surveys or Sinks using conventional means due to the high Feed speeds of the surfaces in production are not are visible.
  • a generic reflection device is improved in that at least one additional reflection element is arranged with a reflection region which is independent of the flat reflection element and which can be set independently of the flat reflection element.
  • the additional reflection element forms a supplementary reflection surface, which is generated essentially by reflection light beam planes that the of intersects the flat reflecting surface formed light beam planes. This is an essential reason for creating the desired one Light.
  • the adjustability regardless of the flat element includes one originally separately set and fixed state as well as one later adjustable version.
  • the additional Reflection element between the light source and the flat Reflection element can be arranged.
  • the additional Reflection element also in an edge area of the flat Reflection element can be arranged, an underlying or a form the adjacent plane and its position and inclination be adjustable relative to the flat reflection element. All of these measures are suitable to provide the desired directional light for each Generate use case.
  • additional Reflection surfaces must be arranged at the level of the strip to be checked.
  • the edge area of the objects to be checked can also be used undercut parts are checked. Tools such as Mirrors, cameras and the like can be used.
  • the distance of the side edges of the additional reflection element facing the light source increase towards the light source from one side edge end to the other.
  • the additional reflection element can thus be oblique from the light source be arranged running away or similar.
  • the light source is not necessarily just one lamp, several lamps can also be used be arranged.
  • the additional reflection element does not provide any as in Light reflectors known in the prior art and also not an element, with which the rays originating from the light source for Reflective surface are deflected, but it provides an additional Reflection surface on which additional rays from the light source coming, directly or after redirection, to be directed from the additional reflective surface to be directed to the work area.
  • a An essential aspect of the invention is that the additional reflection element directs the light rays onto the work area in a different beam path than the flat reflection element.
  • this is additional Reflective element in the form of a strip.
  • the flat reflection element is segmented in an advantageous manner, wherein the individual segments according to a proposal of the invention relative to each other are adjustable.
  • the segments can be the same as for the additional reflective element around lamellar structure Act reflection surfaces. When building the flat reflection element they are at an essentially equal distance from each other arranged.
  • the invention proposes that the flat reflection element and at least one additional one Reflection element are interconnected to form an assembly.
  • Reflection elements by at least one additional reflection surface proposed the one in comparison with that of the flat Reflection element generated beam path deviating beam path generated.
  • a Lighting device To improve the setup and the variable use of a Lighting device is proposed that the unit light source, Deflection reflector and the reflection surface according to the invention in one Support structure are arranged. Such a scaffold can with Fasteners are provided for easy attachment in the Ensure surveillance area.
  • a dimmer device is housed on the Support frame for the control cabinet required for lighting operation arranged in the advantageously a dimmer device is housed.
  • the number of light sources, the deflecting reflectors and the reflecting surfaces depend on the desired range of applications.
  • the Reflection device according to the invention can be a lighting device inexpensive due to the integrated design with few components manufactured and furnished.
  • the device highly variable in terms of their use and only slightly susceptible to faults.
  • the essential aspect of the present invention is that in Reflection area targeted at least two different light deflections be carried out in the viewing and review area targeted mixing of differently deflected light paths, in order to be able to produce the desired verification results.
  • the lighting device 1 comprises one Luminaire 2, a deflection reflector 3 and a reflecting surface 4.
  • the deflection reflector 3 is attached to the connection area 5 on the lamp 2.
  • the Reflection surface 4 is in turn attached to the deflection reflector 3 and via a Adjustment facial expression 6 adjustable.
  • the reflection surface 4 consists of individual reflection slats 7, which in turn are adjustable relative to each other.
  • a dimming flap 8 on the deflection reflector In the beam exit area there is a dimming flap 8 on the deflection reflector arranged, which is rotatably supported on one side via an adjustment mimic 9 relative can be adjusted to the radiation path.
  • the one from lamp 2, deflection reflector 3, reflection surface 4 and anti-glare valve 8 existing assembly is on a support frame 10 arranged. It is a lightweight support structure, to which the assembly is attached by means of retaining tabs.
  • eyebolts 11 for fastening the lighting device 1 arranged in the surveillance area.
  • an attachment profile 12 On the supporting structure 10 is an attachment profile 12, on which the control cabinet 13 with an operator panel 14 is attached.
  • the external dimensions of such Devices are, for example, 1.4 meters x 0.7 meters x 0.5 meters.
  • the device can, for example, be suspended from a ceiling by means of chains be what quick connector such as snap hooks or the like can be used.
  • At the adjustment facial expressions are easy from the outside to easy operating controls, such as plastic balls, arranged as seen in Figure 2.
  • a lamp 15 is inserted into the lamp 2, at which is, for example, a 250 to 400 watt lamp can.
  • the light from the luminaire 2 is first turned on via the deflection reflectors 3 the reflection surface 4, formed from the reflection slats 7, directed from where from the light in a due to the setting of the reflection slats 7th defined beam path is directed into the work area.
  • reflection slats 7 obliquely arranged reflection lamella 16 shown which as an additional Reflection element for a different beam path within a certain area, so that for the respective application required, directed and only indirect light is generated.
  • the embodiment shown is in number and The arrangement of the additional reflection element is not restrictive. So is It is essential that the reflection element comes from lamp 2 and is reflected by deflecting reflectors reflected light and this as directs indirect and directed light into the work area. It is also conceivable to design the anti-dazzle valve 8 as a reflector, but not as an additional one Reflection device.
  • the essential aspect of the present invention is that in Reflection area targeted at least two different light deflections be carried out in the viewing and review area targeted mixing of differently deflected light paths, in order to be able to produce the desired verification results.
  • FIG. 4 A corresponding alternative exemplary embodiment is shown in FIG. 4.
  • two substantially similar lighting devices 1 in different angular arrangements positioned relative to each other, so that the reflection device of a lighting device 1, that is the reflection surface 4 is supplemented by a further reflection surface 4 other lighting device.
  • both lighting devices 1 over have separate light sources that are deliberately managed and mutually exclusive arranged to produce the desired lighting effects can.
  • the different reflections of the individual lighting sources via the respective deflecting reflectors and Fully interfere with reflective surfaces.
