Definitions

  • the invention relates to a device for lighting with a housing, with at least two arranged in this and carried by this lamp and with electrical control means for controlling the lighting means.
  • lighting devices are e.g. for object lighting in shopping centers and in particular in special departments, such as clothing areas used.
  • a lighting device in which a plurality of lamps housed in a common housing are provided with different color temperatures.
  • at least one cold-tone illuminant is present, wherein the light components of the individual luminous means which mix with the total light can be varied in that both illuminants can be driven in opposite directions by means of a stereo potentiometer. Since the light components of the individual lamps can be changed in this device, individual lighting conditions can be generated.
  • the present invention has for its object to further develop a device of the type mentioned in that a lighting technology optimized design is achieved. At the same time, the device should be in Produce a series at an efficient cost with the lowest possible component cost.
  • the device for illuminating objects has a housing with at least two arranged in this and carried by this bulbs.
  • Each of the separate from each other, for generating a respective predeterminable color temperature controllable lighting means has a separate reflector unit, with each of which forms a light chamber. Means are provided for mutual photovoltaic coupling of adjacent light chambers.
  • the means for mutual photovoltaic coupling of adjacent light chambers may be a second reflector assigned to the light sources in common.
  • the second reflector is preferably formed by an arched band extending continuously above the luminous means.
  • the means for mutual photovoltaic coupling of adjacent light chambers are transparent areas on the adjacent reflector units.
  • the light-permeable regions are preferably formed by pinhole apertures in the mutually facing fin regions of the adjacent reflector units.
  • the pinhole diaphragms are preferably each arranged in the region of a middle lamella of the reflector units.
  • the light chambers formed in each case from light sources and the separate reflector units associated therewith are jointly closed by a filter plate towards the object.
  • the filter plate is effective for UV light and cured and preferably partially satinated, leaving a recessed area of the satinization, which lies directly below the light exit surfaces of the light chambers.
  • the housing is e.g. of round or rectangular, in particular square, shape.
  • a housing shoulder is present, which serves the installation of the device whose support in an existing on a building structure recess.
  • the housing shoulder is arranged at the intended installation in a variant on the end facing the room.
  • the housing shoulder is set back in the direction of the second reflector, so that the first reflector protrudes into the space and is surrounded by a preferably translucent ring.
  • the solution is characterized in that a device for illuminating objects arises in which the light chamber of the currently switched off illuminant is illuminated by a light component of the switched on illuminant in the adjacent light chamber. This results in a uniform lighting effect, without causing unwanted dark zones in the overall reflector. This can be achieved without complex components.
  • the lighting device according to the invention has the exemplary shape of a round semi-recessed luminaire.
  • the device consists essentially of a housing 1 with a cylindrical basic shape.
  • the housing 1 is seated within a complementary recess 90, which is introduced into a building structure 9 - for example a room ceiling or a wall panel.
  • a complementary recess 90 which is introduced into a building structure 9 - for example a room ceiling or a wall panel.
  • an outwardly projecting housing shoulder 10 underlines the edge of the recess 90. projecting into the space, the housing 1 is preceded by a ring 15 of preferably translucent material which surrounds the first reflector 5 .
  • the light is generated by two bulbs 2a, 2b, for example high-pressure discharge lamps, wherein the light source 2a has a higher color temperature (colder light color) and the light bulb 2b has a lower color temperature (warmer light color).
  • the two lamps 2a, 2b are held in sockets 4a, 4b , which are fastened to the housing 1 .
  • Housing 1 accommodates other conventional electronic components, such as control members, dimmers and electronic ballasts, which are indicated only schematically, and therefore not are designated.
  • Each of the lighting means 2a, 2b has a separate reflector unit 3a, 3b , which respectively form separate light chambers a, b , which are directed into the interior of a first reflector 5 located thereunder.
  • the first reflector 5 has lateral openings 50 for the light exit.
  • the underside of the first reflector 5 can be closed to the room with a transparent pane 6 .
  • the spatial separation between the light chambers a, b of the reflector units 3a, 3b and the first reflector 5 is effected by a filter plate 7, which is designed as a UV filter plate. It is made of hardened material and is partially satin on its surface, wherein the non-frosted area is arranged as a recessed surface 70 below the light chambers a, b . In addition, the frosted area is brightened by defined stray light.
  • the reflector units 3a, 3b are formed as pinhole apertures 30a, 30b in the region of their mutually facing center louvers .
  • both light sources 2a, 2b there is a continuous second reflector 8 extending along the axis of the light sources 2a, 2b , which is curved in such a way that the light reflected by it is directed downwards into the reflector unit 3a, 3b associated with the light source 2a, 2b shine.
  • the curvature of the second reflector 8 that its virtual focal point is displaced upwards and thus due to the continuity of the second reflector 8 and the light of a luminous means 2a radiates and into the light chamber b of the adjacent reflector unit 3b analog light of other bulb 2b passes into the light chamber a of the second reflector unit 3a .
  • the inventive device operates as follows: There is one of the two bulbs 2a, 2b in the on state, here assumed light source 2a.
  • two clear focus points in the reflector units 3a, 3b are two clear focus points in the reflector units 3a, 3b.
  • This group of figures shows the lighting device according to the invention in the form of a square recessed luminaire.
  • the outwardly projecting housing shoulder 10 of the now rectangular, preferably square housing 1 underlies the edge of the recess 90, but the lighting device closes almost flush with the outer surface of the building structure 9.
  • There is no ring 15 is provided, but the first reflector 5 optionally vortexde disc 6 forms the lower end of the lighting device. Otherwise, the internal structure of the device as well as their mode of action for the previously described round semi-recessed luminaire are identical in principle.
  • This sequence of figures is based on a lighting device, again with a square housing 1, but now in the application as semi-recessed luminaire.
  • the housing 1 is positioned within a complementary recess 90 which is incorporated in the building structure 9.
  • the outwardly projecting housing shoulder 10 underlines the edge of the recess 90, and in turn the housing 1 is preceded by an at least partially transparent ring 15 which surrounds the first reflector 5.
  • the lighting device comes to lie approximately at its average height on the building structure 9, whereby the installation depth is reduced.
  • the internal structure of this embodiment of the lighting device and its operation are similar to the previous embodiments.
