Definitions

  • the invention relates to a recessed luminaire according to the preamble of claim 1.
  • Such recessed lights are known from the prior art in various forms and are offered for example as down-lights or up-lights. These recessed luminaires often have lamp holders whose longitudinal axes extend perpendicular or oblique to the illumination direction or substantially parallel to the mounting surface. In particular, when using compact fluorescent lamps said orientation of the bulb holder is gladly chosen because this orientation allows a small installation depth of the lights.
  • the orientation of the illuminant mount vertically or obliquely to the illumination direction disadvantageously means that the insertion of the illuminant into the illuminant mount is difficult due to confined space conditions and that the illuminant can not be optimally positioned relative to the reflector, since at an optimal position of the reflector Inserting the bulb in the way would be.
  • recessed lights for example, characterized in that the bulb holder and a part of the bulb protrude laterally from the reflector and that in many cases in the reflector on the opposite side of the bulb holder an opening is provided, into which a light source can be introduced with its side facing away from the socket, then to allow insertion of the lamp in the opposite bulb socket.
  • a disadvantage of this embodiment is the fact that in the reflector usually an opening must be provided, which is associated with effort, the effective reflector area reduced and also disadvantageously light through the aperture against the desired direction of illumination can escape.
  • the reflector consists at least of a first reflector region, followed by a second reflector region in the illumination direction, which is detachable from the first reflector region in order to enable a lamp exchange.
  • the luminous means holder and the luminous means in front of the first reflector region. Accordingly, at least parts of the second reflector region can be arranged in front of the luminous means, so that the luminous means is as it were located between the first and the second reflector region.
  • the luminous means held in the luminous means holder is then freely accessible and can be detected by a person without hindrance by the second reflector region and detached from the luminous means holder of the linear luminaire.
  • the first reflector region of the linear luminaire is designed as an additional reflector and the second reflector as an elongated direct-light reflector, wherein between the additional reflector and direct light reflector are light passage areas through which a light component can pass, which is ultimately used to produce an advantageous, glare-free, diffuse illumination.
  • the direct light reflector on the other hand, is directly and directly exposed to a proportion of light which is used to produce direct illumination.
  • an elongate reflector opening of the direct-light reflector which is located in the illumination direction defines a direct-light exit region, to whose two sides a likewise elongated diffuse-light exit region is present. The diffuse light exit region is thereby exposed to a light component which has previously passed through the said light passage region, which is formed between the additional reflector and the direct light reflector.
  • a disadvantage of the document DE 101 12 055 A1 known linear field light is the fact that it can be produced only with relatively high effort, since the two diffuse light exit regions extending on both sides of the direct light exit region, must be made in a complex manner from each of a translucent, specially shaped element, each on the entire length of the field lamp extends.
  • Each of the two translucent, specially shaped elements must be connected separately at several positions with the luminaire housing, so that the said elements then ultimately together with the housing in each case form a closed, not readily openable chamber. Consequently, the two chambers can only be cleaned at the expense of a great deal of effort. Specifically, it is to clean a strip lamp according to DE 101 12 055 A1 it is necessary first to release the direct light reflector from the housing, whereupon the two translucent elements, each forming a diffused light exit region, must then be successively removed.
  • An object of the invention is to develop a recessed downlight usable in particular according to the preamble of claim 1 in a simple manner such that even in the presence of an advantageous glare-free diffuser light exit area in addition to a direct light exit area economically advantageous manufacture and maintenance of the lamp becomes possible.
  • the inventively provided and connected to the direct light reflector disc can be performed in the diffuse light exit area as a diffuser or in a less expensive version as a perforated plate.
  • the disc can cover both the diffuse light exit region and the direct light exit region, in which case it is transparent in the direct light exit region.
  • the direct light exit region can also be made open.
  • the second reflector region with the disk from the first reflector region is either wegschwenkbar or completely detachable.
  • the second reflector region with the pane does not have to be handled as a separate part when replacing a lighting device, since the second reflector region with the disc due to its articulated connection with the recessed light is always held on this.
  • With a complete solubility of the second reflector region including the disk of the recessed luminaire it is advantageous that it can be realized with little economic outlay.
  • Illuminant holder and first reflector region can preferably be arranged in a housing, on which the second reflector region is articulated to the disc and / or fastened by means of a detachable screw, magnetic, clip, latching or bayonet connection.
  • 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 second reflector region may have a reflector opening located in the illumination direction, which in one possible embodiment is terminated by a translucent or transparent pane at least substantially dust-tight.
  • a frequent cleaning of the reflector areas and the light source can be avoided, since said disc forms a reliable protection against dust.
  • a particularly good protection against dust can be achieved if not only the reflector opening is closed by means of a disk, but if the entire housing at least substantially dust-tight by the second reflector region releasably secured to the housing with the disk and / or by firmly connected elements is completed. In this case, entry of dust into any housing or reflector areas can be reliably avoided.
  • the first and the second reflector region can adjoin one another at least in sections.
  • the two reflector regions can jointly take the form of a uniform reflector, which is closed on its opposite side of the reflector opening.
  • the closed side of the reflector is formed in this case by the first, in particular inextricably connected to the housing reflector region. If the first and second reflector regions adjoin one another not only in sections, but at least almost completely, it is advantageous if one of the two reflector regions has an opening which is open towards the other reflector region, through which the luminous means can protrude laterally into the interior of the reflector. At the same time, this cutout makes it possible to detach the second reflector region from the first reflector region without the luminous means standing in the way of such loosening.
  • the provision of the diffuse light exit region according to the invention in addition to the direct light exit region makes it possible to work in the direct light exit region after the dark light principle avoiding a glare effect and at the same time to ensure that non-glaring scattered light from the diffuse light diffuser according to the invention is applied around the direct light exit region.
  • the direct light exit region and the diffuse light exit region can be acted upon by a common illuminant that can be attached in the illuminant mount. In this case, no separate light source must be provided for the diffuse light exit region according to the invention.
  • the additional reflector Due to the concrete shape of the additional reflector, a predefinable division of the portion of the reflected light conducted to the direct light exit region and to the diffused light exit region can be ensured. Thus, by the shape of the additional reflector, the distribution of the light components conducted to the direct light exit region and to the diffused light exit region can be selected in the respectively desired manner.
  • a particularly good diffuse light illumination results when the diffuse light exit region is acted upon by an illuminant that can be inserted into the illuminant mount only indirectly via the additional reflector.
  • the additional reflector can be formed by at least one flat reflector surface which extends parallel to the plane of the installation surface. Alternatively, this reflector surface can also be designed in particular rotationally symmetrical curved or kinked. The said reflector surface can be formed either specular or diffuse reflective. It is particularly advantageous if the inner surface of the housing carrying the illuminant mount is formed at least in regions as an additional reflector. When using such, open in the direction of illumination housing in particular the housing bottom can be formed as a reflector surface, which forms at least a portion of the additional reflector. Also, the side walls of such a housing can be designed to be reflective or diffuse reflective and thus act as further regions of the additional reflector. When forming the housing bottom or the housing side walls as additional reflector is achieved in an advantageous manner that no additional components are required for the additional reflector. It is only necessary to equip the housing on the inside with the respective desired reflection behavior.
  • the housing carrying the luminous means holder has a substantially cuboid shape and the illuminant means mountable in the illuminant mount has an elongated shape, wherein the longitudinal axis of the illuminant mount extends along a diagonal of the cuboid housing in a plane extending parallel to the mounting surface. Since the length of these diagonals is dimensioned larger than the length of the side surfaces of the housing, stands by the said arrangement for the insertion and removal of the illuminant, a comparatively large space available, through which said operations are easier to handle.
  • Fig. 1 shows a schematic cross section through a recessed luminaire according to the invention.
  • the recessed luminaire shown has a substantially cuboidal housing 10, which is open in the illumination direction and has a peripheral frame 9 on its open side.
  • the illumination direction facing away from the side of the frame 9 abuts against a mounting surface 11, which is formed for example by the underside of a suspended ceiling element 12.
  • a direct light reflector 4 is mounted, which has a first, circular opening in the illumination direction, which coincides with a direct light exit region 1.
  • the direct light reflector 4 forms the above-explained second reflector region in the sense of the invention.
  • the direct light reflector 4 At its end facing away from the direct light exit region 1, the direct light reflector 4 has a further, likewise substantially circular opening facing the bottom of the housing 10, from which part of the light quantity emitted by a light source 6 opposes the illumination direction from the direct light reflector 4 in the direction of the light source Bottom of the housing 10 can escape.
  • the direct light reflector 4 in this case has a tapering in the direction of the bottom of the housing 10 and in a possible embodiment at its end facing away from the direct light exit region 1 a cutout 14 to make room for the version of the bulb 6.
  • the bottom of the housing 10 forms a portion of a waivereßektors 7.
  • Other areas of the additional reflector 7 are formed by the side walls of the housing 10.
  • the additional reflector 7 forms the above-explained first reflector region in the context of the invention.
  • the area to be illuminated facing the housing 10 is completed in a possible embodiment by a disc 13, which has different optical properties in different areas.
  • the pane In the direct light exit region 1, the pane is made completely transparent, so that light coming from the light source 6 can pass unhindered through this area.
  • 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.
  • the disc 13 in a more cost effective variant as perforations exhibiting ring element, in particular as a perforated plate with a small hole size, in which case it is advantageous if the direct light exit region is not closed off by means of a disk but is made open.
  • FIG. 1 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 light beam also shown only by way of example in FIG. 1, strikes the reflecting inner side of the direct light reflector 4 from the light source 6, from where the light beam is again directed through the transparent area of the pane 13.
  • An additional, again only exemplarily illustrated in Fig. 1 light beam strikes from the light source 6 at an acute angle to the additional reflector 7, from where the light beam is also directed through the transparent region 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.
  • part of the light supplied by the light source 6 also passes into the light passage area formed between the 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 passing under multiple reflection to the diffuse light exit region 2 is likewise shown by way of example in FIG. 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 ultimately strikes the area formed as a disc 13 of the disc.
  • This lens area ensures that the light beam is converted into diffused light, which emerges from the diffuse light exit area 2 and marks the direct light exit area 1 in the manner already explained, which leads to the mentioned, pleasant lighting mood in the room.
  • the disk 13 is detachable from the housing 10 and from the frame 9 together with the direct light reflector 4 fastened to it.
  • the disc 13 in its edge region for example, have magnetic elements which cooperate with the example ferromagnetic frame 9.
  • the release of the disc 13 from the frame 9 can then be done simply by a decrease in the same, in which the magnetic forces acting between said magnetic elements and the frame 9 are overcome.
  • the disc 13 can be pivotally held on the frame 9 and in particular fastened or latched by means of a clip connection.
  • FIG. 2 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 (analogous to FIG. 1).
  • the direct light exit region 1 ' is delimited at its outer circumference by a circular line 19 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, which also runs along the circle line 19.
  • the direct light reflector extends into the plane of the drawing up to a rear, opposite to the illumination direction, not shown in FIG. 2 reflector opening.
  • a light source 6 " Arranged within the direct light reflector is a light source 6 ", which is designed as an elongated compact fluorescent lamp Alternatively, the light bulb 6" could also be arranged behind or above the direct light reflector.
