Definitions

  • the present invention relates to an interior lamp, especially for lighting goods presentation areas, with a transparent lampshade and a optical system with a lamp.
  • Goods presentation areas such as refrigerated counters, Fruit chests, shelves etc. are usually artificially lit.
  • the aim is to create the surfaces Illuminate as evenly as possible.
  • interior lights of the aforementioned Type used with transparent lampshades This conventional interior lights have the disadvantage that they run out of glare because the illuminant from visible on the outside as a particularly bright spot or surface is.
  • the interior lights have only a small one Light control with the result that only a small one Part of the lamp luminous flux actually is the one to be illuminated Usable space meets.
  • each one create a circular, luminous surface.
  • luminaires with a horizontal are therefore also used Illuminants used, the oval luminous surfaces produce.
  • Illuminants For lighting elongated presentation areas put these lights with a lying Illuminants are an improvement, but the Luminaire shade still illuminated unevenly.
  • the object of the invention is therefore to provide an interior light type mentioned so that the lampshade is evenly illuminated and in particular Glare can be avoided.
  • optical system in one above the lampshade provided illuminant space is positioned and by a light entry opening at the top of the lampshade shines in this light, and that at the bottom Edge of the lampshade an inwardly protruding, diffuse reflective web is provided, the at least one Part of the emerging light is reflected back into the lampshade.
  • the lampshade made of translucent material, For example, an acrylic material that due to its Surface structure totally reflective properties having. This surface structure creates a uniform illumination of the lampshade still supported.
  • the illuminant is a high-pressure discharge lamp in a lying position Burning position is.
  • high-pressure discharge lamps By using such high-pressure discharge lamps is the concentrated generation of high luminous flux and thus a high power conversion possible in a small space. It also allows Use of such lamps in the burning position if necessary in combination with appropriate reflectors, which, for example, create a batwing light distribution, Illuminate elongated surfaces evenly, so that the number of lights that are used for illumination an elongated presentation area is required is, can be kept low.
  • ballasts used when using such high-pressure discharge lamps may be required, for example in an adjacent to the lamp room and in particular above this intended equipment room be provided by the lamp room is thermally insulated so that the ballasts through the heat generated during operation by the Illuminants are not affected.
  • Heat shields may be provided.
  • the web at the bottom of the lampshade partially translucent and the let through Diffuse light.
  • the Bridge as well as the lampshade made of an acrylic material consist.
  • the web can be selectively reflective to filter out certain color components.
  • the light entry opening of the lampshade Filters upstream of the certain color components filters out the light emitted by the illuminant in order to to emphasize the complementary colors.
  • the interior lamp 1 which in particular for illuminating elongated areas such as Freezers, fruit boxes, shelves etc. can be used, includes a round lampshade 2 made of a transparent acrylic material that adheres to a smaller light entry opening 2a on its upper side and a larger light entry opening on its underside 2b. Under the lamp room 3 is with attached a projection 3a of the screen 2, which Light through the light entry opening 2a into the luminous chim entry.
  • a box reflector 6 usual design held to its for Light entrance opening 2a of the lampshade 2 pointing Bottom is open.
  • the high-pressure discharge lamp 5 can for example as a metal halide lamp or as a high pressure sodium lamp trained with improved color rendering his.
  • An operating device room is located above the lamp room 3 7 provided in which the ballasts for the high-pressure discharge lamp 5 are accommodated.
  • the Illuminant room 3 and the equipment room 7 are thermally insulated from each other. For this purpose, between the two rooms 3, 7 two heat shields 8 are provided.
  • a filter 10 is provided, which from the light before entering the lampshade Filtered out 2 specific color components.
  • the surface of the reflector 6 be selective reflective.
  • annular Web 9 provided in the light exit opening 2b protrudes and limits them.
  • This web 9 is made from a partially reflective and partially diffuse scattering material, such as acrylic.
  • the placement of the Illuminant 5 in the illuminant space 3 outside the Lampshade 2 achieves that the lamp 5 itself is not immediately visible to a viewer and especially not as a bright spot in the lampshade looming.
