Definitions

  • the invention relates to a recessed luminaire according to the preamble of claim 1.
  • Built-in lights are known from the prior art in many forms.
  • "dark-light lights” eg corresponding DE-A-38 26 676 , known, in which the illuminant and reflector are arranged to each other so that the light source from a certain viewing angle is neither directly nor specularly visible on the reflector and thus can develop no glare.
  • this avoidance of a glare effect also means that the ceiling area of a room illuminated in this way remains largely unlighted and the relationship between the light source and the illuminated area perceived as natural by humans is lost since it is not possible to know from which light source the light originates.
  • recessed luminaires are also known from the prior art in which, on the one hand, according to the dark-light principle, a dazzling effect is avoided and, on the other hand, it is ensured that the persons located in the illuminated room consciously or even unconsciously perceive the light sources used for the illumination can, so that a natural relationship between the light source and the illuminated area created and a lighting technically warm room climate is obtained. This is achieved by the fact that the direct light exit area is surrounded by a non-glare diffuse light exit area.
  • One object of the present invention is to develop a downlight having a diffuse light exit region surrounding a direct light exit region in such a way that the production costs of the downlight are significantly reduced and it can be ensured that the efficiency of the downlight is lower despite the reduced production costs long-term contamination, especially dust, is not affected.
  • light-emitting means and direct light reflector are arranged in a housing whose inner surface is at least partially formed as an additional reflector, and that the housing in the region of the diffused light exit region by a translucent lens and in the region of the direct light exit region is completed by a particular transparent disc at least largely dustproof.
  • an additional reflector is thus provided in addition to a conventional direct light reflector, which is formed in the simplest way by a suitably designed or coated inner surface of the lamp housing.
  • This additional reflector according to the invention can then direct light from the illuminant to the diffuse light exit region and thus ensure a sufficient amount of light in the diffuse light exit region. This desired effect is achieved in contrast to the prior art with an extremely simple reflector structure.
  • the additional reflector according to the invention in contrast to the main reflector according to DE-A-43 36 023 - Must have no special surface finish, should be avoided according to the invention that this additional reflector from the viewer of the downlight according to the invention is directly visible, which erfindungsgeznäß is achieved in that the diffused light exit region is completed by a translucent lens.
  • the additional reflector light is directed to this translucent lens, which then emits scattered light, inter alia, in the direction of a viewer, without the viewer can see the additional reflector behind the translucent lens directly.
  • the said diffuser serves in an extremely advantageous manner at the same time to prevent entry of dust into the luminaire according to the invention through the diffuse light exit region.
  • the direct light exit region is additionally completed according to the invention by a particular transparent pane. Since both the translucent lens diffuser the diffuser light exit area and the other disc the direct light exit area at least largely dustproof, can be ensured for long periods of operation of the downlights invention with high efficiency without impaired by dust deposits.
  • the diffuser light exit region according to the invention offers interesting design options, for example by an individual choice of the shape of the diffuse light exit region or the color of the exiting scattered light.
  • the reector opening defining the direct light exit region can be assigned to its direct light reflector, on whose side facing away from the direct light exit region an additional or background reflector is provided which illuminates both the direct light exit region and the diffuse light exit region.
  • the illuminant radiates to a direct light on the Minilichtreflek gate in the actual illumination direction and the other in one of the direction of illumination Mechanism1313rich direction to the additional reflector, which the incident light on him as a function of Its design partly in the direction of the diffuse light exit region and partly directs to the direct light exit region, so that this additional reflector also contributes to the increase in efficiency in the direct light generation.
  • This additional reflector can reflect either specularly or diffusely, wherein in the former case in the region of the diffuse light exit region, a conversion of directly reflected light in the scattered light can take place.
  • a light passage region is formed between the additional reflector and the direct light reflector, so that the additional reflector can direct that part of the light which is to correspond to the diffused light component to the outside of the direct light reflector past the diffused light exit region.
  • the diffuse light exit region can be acted upon both via the additional reflector and directly via the illuminant, but it is advantageous if this application takes place exclusively indirectly via the additional reflector.
  • the supplemental reflector may be formed by at least one flat or suitably shaped receptacle surface. As already mentioned, this reflector surface may be formed either specularly or diffusely reflecting. By a suitable curvature or buckling of the additional reflector, the ratio of the light components, which are directed to the direct light exit region and the diffused light exit region, can be adjusted in a targeted manner. To achieve a high efficiency of the recessed luminaire according to the invention, the additional reflector is formed so that a high proportion of light to the direct light exit area and only a small amount of light reaches the diffuse light exit area.
  • the inner surface is at least partially formed as an additional reflector is particularly advantageous.
  • the housing bottom can be formed as a flat or suitably curved or kinked reflector surface, which forms at least a portion of the additional reflector.
  • the side walls of such a housing can be designed to be reflective or diffuse reflective and thus act as further reflector areas.
  • a metal housing untreated with regard to its surface, which has intrinsic reflective properties, can be used.
  • the housing it is advantageous if this is made light-tight, since in this case, for example, in suspended ceilings inaccuracies in the processing are not inadvertently illuminated from behind. Furthermore, the housing can be made dustproof, so as to counteract such a pollution caused by air conditioners, for example, bulbs and reflectors.
  • the direct light reflector is formed on its inside as well as the reflectors known recessed lights preferably specular to achieve a defined lighting characteristics and good efficiency.
  • the direct-light reflector can be designed to be reflective or diffusely reflecting, so that the light which acts on the diffuse-light exit region can also be conducted via the outside of the direct-light reflector.
  • the outside of the direct light reflector in this case forms an area of the additional or background reflector.
  • the luminous means of a recessed luminaire according to the invention can be located either within the direct light reflector and / or between direct light reflector and additional reflector. In this arrangement options of the bulb ensures that the bulb can act on both the direct light reflector and the additional reflector.
  • the diffuse light exit region can be completed in the illumination direction by a translucent lens. This is particularly appropriate when the additional reflector is designed to be reflective, since in this case the diffuse light exit region is acted upon by directly reflected light, which is convertible into diffuse light by means of said diffusing screen.
  • the housing of the recessed luminaire according to the invention in the region of the diffused light exit region through the lens and in the region of the direct light exit region by a in particular transparent disc is at least largely dustproof completed. In this way, a frequent cleaning of the direct light and additional reflector and the light source can be avoided because the said discs form a reliable protection against dust.
  • the transparent pane associated with the direct light exit region and the translucent diffusion plate associated with the diffuser light exit region can in particular be designed in one piece. Such a one-piece pane then only needs to be treated differently in its areas associated with the direct light and the diffuse light exit areas, so that the pane acts as transparent in the direct light exit area and as scattering in the diffuse light exit area.
  • the direct light exit region may preferably have a circular shape, but also any other shapes.
  • the direct light exit region can also have an elongated shape, so that it is possible to use the recessed luminaire according to the invention as a linear luminaire.
  • the diffuse light exit region can be bounded on the inside by the outer contour of the direct light exit region, in particular by a circular line. On the outside, the diffuse light exit region can have any shape. It is preferred if the diffuse light exit region is bounded on the outside by a polygonal, in particular a rectangular or square line or by a further circular line.
  • the direct light reflector can be held pivotably in the housing, so that the primary illumination direction, which is determined by the direct light reflector, is adjustable.
  • advantageous design effect can be achieved, in particular it is possible to give a plurality of recessed luminaires according to the invention, which are used together as a system, a uniform appearance, regardless of which angular position of the pivotable direct light reflector has relative to the housing. It is important that even with swiveling direct light reflector of the diffuse light range unchanged ensures a visible mark the light source with the resulting advantages.
  • the direct-light exit region and the diffuse-light exit region can be tilted in relation to the installation surface in such a way that they are in their inclined position substantially within a common plane inclined to the installation surface.
  • an inclination of the direct-light exit region relative to the diffuse-light exit region can be achieved, while the diffuse-light exit region bears a fixed position relative to the housing.
  • the direct light reflector can be held pivotably in the housing together with the light source.
  • Fig. 1 shows a recessed luminaire according to the invention in plan view, which has a direct light exit region 1 and a diffuser light exit region 2 surrounding it.
  • the direct light exit region 1 is delimited at its outer circumference by a circular line 3, which at the same time represents the inner boundary of the diffuse light exit region 2.
  • the direct light exit region 1 extends in the plane of the drawing in the same plane as the opening in the direction of illumination of a direct light reflector 4, which also runs along the circular line 3.
  • the direct light reflector 4 extends into the plane of the drawing up to a direction opposite to the direction of illumination rear reflector opening, which is bounded by a circular line 5.
  • the circular line 5 runs concentrically to the circle 3 with a reduced radius compared to the circle 3.
  • a light source 6 is arranged, which is designed as a compact fluorescent lamp.
  • an additional or background reflector 7 is provided, which extends in the example shown in a direction parallel to the plane extending plane.
  • the relative arrangement of direct light reflector 4, light source 6 and additional reflector 7 is described below with reference to Fig. 2 explained in more detail
  • the diffuse light exit region 2 which is bounded on the inside by the circular line 3, is bounded on the outside by a square line 8, which in turn forms the inner boundary of a frame 9 of the illustrated downlight.
  • the frame 9 is located with its side facing away from the direction of illumination on a mounting surface, not shown, in particular a ceiling and thus covers together with the recessed frame held in the frame 9 a provided for receiving the downlight, existing in the mounting surface opening.
  • direct light from the luminous means 6 reaches the direct light exit region 1, the direct light exit region 1 being acted upon directly by the illuminant 6 and by the light reflected by the direct light reflector 4 and the additional reflector 7.
  • This light emerging via the direct light exit region 1 provides the actual lighting desired with the recessed luminaire shown, with the lighting characteristic required in each case and the desired efficiency.
  • Fig. 2 shows a schematic cross section through a recessed luminaire according to Fig. 1 , where the same reference numerals are used as in the explanation of Fig. 1 ,
  • the recessed luminaire shown has a substantially cuboidal housing 10, which is open in the illumination direction and has the peripheral frame 9 on its open side.
  • the lighting direction facing away from the side of the frame 9 is located on a mounting surface 11, which is formed for example by the underside of a suspended ceiling element 12.
  • the direct light reflector 4 is mounted, which has a first opening in the illumination direction, which coincides with the direct light exit region 1. At its end facing away from the direct light exit region 1, the direct light reflector 4 has another opening facing the bottom of the housing 10, from which part of the amount of light emitted by the light source 6 opposes Lighting direction can escape from the direct light reflector 4 in the direction of the bottom of the housing 10.
  • the direct light reflector 4 has a shape that tapers in the direction of the bottom of the housing 10 and a cutout 16 at its end facing away from the direct light exit region 1 in order to make room for the socket of the luminous means 6.
  • the bottom of the housing 10 forms a region of the additional reflector 7. Further regions of the additional reflector 7 are formed by the side walls of the housing 10 and by the outside of the direct light reflector 4.
  • the area to be illuminated facing the housing 10 is closed by a disc 13, which has different optical properties in different areas.
  • the disc In the direct light exit region 1, the disc is made completely transparent, so that light coming from the illuminant 6 can pass unhindered through this disc region.
  • the pane 13 In the diffuse light exit region 2, on the other hand, the pane 13 is designed as a diffusing screen, which diffuses light impinging on it from the inside of the housing and thus produces diffuse light.
  • the lens area extends up to the outer edge of the frame 9, so that the frame 9 is covered by the scattered light region of the disc 13.
  • Fig. 2 By way of example, three light beams emanating from the illuminant 6 are shown, which impinge directly on the transparent region of the disc 13 from the illuminant 6 and, due to the transparency of the disc 13, pass through them unhindered.
  • Another, also exemplary in Fig. 2 illustrated light beam strikes from the light source 6 to the reflecting inside of the direct light reflector 4, from where the light beam is in turn directed through the transparent area of the disc 13.

  • Light rays of the type mentioned, which pass through the transparent region of the pane 13 and thus the direct light exit region 1, provide for the desired with the recessed luminaire according to the invention room lighting.
  • a part of the light supplied by the light source 6 also passes into the light passage area formed between direct light reflector 4 and the bottom of the housing 10, so that it can reach the diffuse light exit area 2 by single or multiple reflection.
  • a light beam reaching the diffuse light exit region 2 under multiple reflection is in Fig. 2 also shown as an example. Starting at the light source 6, this light beam strikes the bottom of the housing 10 at a less acute angle and is reflected from there to the side wall of the housing 10. Subsequently, there is a multiple reflection between said side wall of the housing 10 and the specular outside of the direct light reflector 4, until the light beam finally on formed as a spreading disc area of the disc 13 strikes.

  • the solid lines of the Fig. 3 show a recessed luminaire according to the invention, which, except for the following differences identical to the recessed luminaire according to Fig. 2 is trained.
  • Fig. 2 In contrast to Fig. 2 is the recessed light according to Fig. 3 not completed by a one-piece disc 13. Instead, the opening in the direction of illumination of the direct light reflector 4 is terminated with a transparent pane 14 which does not extend beyond the outer periphery of the direct light reflector 4.
  • the transparent pane 14 is surrounded by a diffuser 15, the inside by the circular line 3 according to Fig. 1 and on the outside by the square line 8 according to Fig. 1 is limited.
  • An essential difference to the recessed luminaire according to Fig. 2 Accordingly, it is that the housing 10 in the illumination direction by a two-part disc 14, 15 is completed.
  • FIG. 2 Another significant difference compared Fig. 2 consists in that the direct light reflector 4 is movably, in particular pivotally mounted in the housing 10 together with the lamp 6.
  • the direct light reflector 4 together with the light source 6 in the in Fig. 3 dashed shown to bring position, which has the consequence that the illumination direction of the direct lighting is no longer perpendicular, but now inclined to the mounting surface 11.

  • the lens 15 remains unchanged in its position, that is, it continues to extend parallel to the mounting surface 11. This leads to a uniform, advantageous appearance of an arrangement of several recessed lights according to the invention, even then if only the direct light reflector 4 is pivoted in individual recessed lights or if the direct light reflector 4 is pivoted in different directions in different directions. It is again important that the already explained marking function of the scattered light regions remains unchanged.
  • the recessed light according to Fig. 4 has a substantially cuboidal housing 10, which is open in the illumination direction and has a circumferential frame 9 on its open side. On its outside, the housing 10 is provided with resilient clamps 17, which serve to fix the housing 10 in a ceiling element 12.
