Definitions

  • the invention relates to a vertical lighting device and an outdoor lighting device.
  • Vertical lighting devices are used, for example, for outdoor lighting, in particular in connection with path or street lighting.
  • lighting elements radiating downwards can be mounted on, on or in lanterns, for example to illuminate streets or sidewalks from above.
  • different types of lighting elements are known.
  • the light source emits directly downwards.
  • the light intensity distribution can be influenced by means of a reflector surrounding the light source or a lens optic.
  • the disadvantage of this type of construction is that a lantern carrying the lighting element must have a section pointing downwards towards the street or towards the path so that the street or path can be illuminated directly.
  • Known vertically radiating lighting systems are designed to be uniformly luminous in a semicircle or in a full circle around the vertical lighting unit. With this principle, it is not possible to illuminate horizontal evaluation areas in the outside space, such as paths and streets, in accordance with the given technical standards for the illumination of such defined evaluation areas.
  • Diffuse light units radiating in a semicircle or in a full circle around the vertical light unit regularly do not meet the glare control requirements for street lighting, so that applicable standards for street lighting with different road users and intersecting traffic routes are not complied with.
  • cylindrical or polygonal-shaped vertical lighting elements use vertically single- or multi-storey lighting elements arranged horizontally to the traffic route, in which reflector elements or comprehensive optical lens elements are used which correspond to the use of the traffic route and which surround one or more light sources arranged on the horizontal planes.
  • the object of the invention is to create a vertical lighting device and an outside lighting device with which a surface area to be illuminated can be illuminated in an improved manner.
  • a vertical lighting device which has the following: a carrier component which is arranged upright with respect to a surface to be illuminated and in this case extends in the vertical construction direction; a light source which is arranged on the carrier component and has a preferred light emission in the horizontal direction; a first light guide element which is assigned to the light source and is arranged on the carrier component on one side of the light source, a first reflector surface formed on the inside of the first light guide element being inclined with respect to the vertical direction of construction towards the second light guide element; and a second light guide element, which is formed separately from the first light guide element and is also assigned to the light source and is arranged on the carrier component on an opposite side of the light source, a second reflector surface formed on the inside of the second light guide element in relation to a horizontal assembly direction that is opposite to the vertical assembly direction runs transversely, is inclined towards the first light guide element.
  • the first and the second light guiding element are jointly comprised for light guiding by a reflector arrangement with which the light emitted by the
  • an outside lighting device for lighting a floor surface in the outside area with the vertical lighting device.
  • the reflector arrangement can consist of the first and the second light guide element.
  • the first light guide element deflects light emitted horizontally by the light source in the preferred emission direction, in particular in the direction of the second light guide element.
  • the light is guided in particular on the basis of light reflection.
  • Components assigned to the light source can be arranged on the carrier component, for example a cooling device assigned to the light source, for example a heat sink.
  • a cooling device assigned to the light source for example a heat sink.
  • other wiring elements can also be arranged on the carrier component.
  • Electrical connections can also be accommodated on the carrier component.
  • the carrier component can be formed with a circuit board on which circuit elements and the light source are arranged.
  • One or more light-emitting diodes can be used as the light source.
  • a light source can be used which emits the generated light predominantly or essentially completely in the preferred light emission direction.
  • the reflector surfaces can be provided with different surface structures, which enables the reflector surfaces to be prepared for preferred reflection directions, for example.
  • a surface structuring with a honeycomb structure is formed on the reflector surfaces.
  • the second light guide element can be arranged partially or essentially completely covering the light source in the viewing direction from the front onto the carrier component. In this way, a glare protection element is formed in the viewing direction from the front onto the carrier component.
  • the second reflector surface can be inclined with respect to the horizontal direction of construction at an angle of approximately 30 degrees to approximately 60 degrees to the first light guide element, alternatively at an angle of approximately 40 degrees to approximately 50 degrees. In one embodiment, the angle can be approximately 45 degrees.
  • the first reflector surface can be inclined with respect to the vertical direction of construction at an angle of approximately 10 degrees to approximately 40 degrees to the second light guide element, alternatively at an angle of approximately 20 degrees to approximately 30 degrees.
  • the first reflector surface can be designed as an essentially flat reflector surface with a slight surface curvature.
  • the first reflector surface can overall have an angular shape, for example be square.
  • partial reflector surfaces can be provided which in turn have an angular surface shape, for example a square surface shape.

  • the reflector element can be formed separating or separating from one another on the first reflector surface adjacent highly reflective surface sections.
  • a lateral glare shield can be formed on the edge of the second reflector surface.

  • the lateral glare protection can be formed on one or both sides with a respective wall section which is arranged upright or protruding in relation to the second reflector surface.
  • the side glare protection can have a light-reflecting surface.
  • the reflection behavior in the area of the side glare protection can be the same as or different from the reflection behavior in the area of the second reflector surface. For example, a diffuse reflection can be provided on the side glare protection, whereas the second reflector surface is highly reflective in this or other embodiments.
  • the light source can be assigned a lens device or lens system which is set up to guide light which is emitted laterally by the light source and not in the direction of preferred light emission.
  • the lens device can be set up to guide or guide the light received by the lens device from the light source onto the first reflector surface.
  • the lens device can be arranged encompassing the light source on several sides.
  • a light-guiding or light-guiding section of the lens device can in this case be semicircular.
  • the lens device can overall have a U-shape, in which case and in other embodiments the lens device can have a mounting part in addition to the light-guiding section.

  • the second light guide element can have a protruding edge section on an edge which is distal with respect to the carrier component and which is arranged opposite the light source. This creates a supplementary or alternative glare protection.
  • the protruding edge section can be designed to taper in an end region which is distal in relation to the second light guide element.
  • At least one further light source with an associated further reflector arrangement can be arranged on the carrier component in a stacked arrangement extending in the vertical direction of construction, which is designed corresponding to the reflector arrangement with the first and the second light guide element.
  • a plurality of light sources, each with an associated arrangement of light guide elements, are formed on the upright support component.

  • several light sources with an assigned reflector arrangement illuminate the same (partial) area to be illuminated.
  • the plurality of light sources with an associated reflector arrangement can be arranged on the carrier component directly adjacent to one another, as a result of which the respective first reflector surfaces form a wall-shaped arrangement of first reflector surfaces.
