Definitions

  • the invention relates to a stationary light-emitting unit with a number of small-sized light-emitting devices, in particular LEDs.
  • Such stationary light emitting units are known in the form of so-called. Radiators. These are used for example on the outside of buildings for illuminating paths around the building, but also for illuminating, for example, trees in parks. Such radiators therefore generally have a substantially watertight housing for outdoor use. Especially when using light-emitting diodes (LEDs) emit these lights mostly light in cold tones. For the user, however, is more pleasant a light in warm tone.
  • LEDs light-emitting diodes
  • an optical lens e.g. used in polycarbonate.
  • the use of such a lens is disadvantageous due to the light absorption of the lens material, i. the precission of such a lens causes the brightness of the radiated light to be reduced by between 10 and 15 percent.
  • this is not desirable because the light output of such a light-emitting unit would then be less high.
  • the present invention is therefore based on the object, a stationary light-emitting unit with a number of small-sized light-emitting devices, in particular LEDs, to the effect that the emitted light has a warm tone and the emitted light can be directed without loss of light due to absorption.
  • a stationary light-emitting unit with a number of small-sized light-emitting devices, in particular LEDs, is provided, in which at least a part of the light-emitting devices are each surrounded by at least one reflector device or associated therewith at least one respective reflector device.
  • the light emitted by the small-sized light emitting device is reflected light and by the shape of the reflector can now the radiation angle, i. the light distribution in the room can be determined.
  • a lens made of polycarbonate when the at least one reflector device is provided, a reduction in light or a loss of light due to absorption is avoided.
  • the respective light-emitting devices of the stationary light-emitting unit and the reflector means are suitably arranged to emit this light optimally reflected.
  • the reflector device in the manner of a waffle pattern distributed over the surface of the light-emitting unit.
  • a different arrangement of both the light emitting devices (e.g., LEDs) and the reflector means associated therewith is possible.
  • such an arrangement is selected which appears most sensible for the particular application of the stationary light-emitting unit, wherein both rounded or elliptical or circular arrangements as well as rectilinear and planar arrangements and mixed forms can be formed.
  • At least one reflector device can be designed flat. Furthermore, it is possible for at least one of the reflector devices to be designed parabolically or in the manner of a parabolic mirror. It is also possible to provide at least one of the reflector devices with surfaces which are at an angle to each other. In particular, four surfaces that are at an angle to one another can surround a respective light-emitting device, so that a wide-angle emission of light is possible. In a training in the manner of a parabolic mirror, the light-emitting device is advantageous centrally in the arranged parabolic reflector device, so that also here a emitting or emitting light reflected at a large angle is possible.
  • the angle of this infinitely large, with a very wide-angle radiation from the light-emitting device is possible.
  • Mixed forms of the aforementioned shapes of reflector devices are possible.
  • any other shapes for the reflector devices can be provided, in which the light-emitting devices emit light with a desired emission angle after the reflection.
  • the light-emitting devices are each arranged centrally in the reflector devices. In principle, however, it is also possible to arrange them off-center, for example, if radiation in one direction is to be intensified.
  • respective light-emitting devices in particular LEDs, associated reflector devices and partially different beam angles at the respective light-emitting devices can be generated. As a result, custom-tailored customized solutions can be created easily.
  • the further reflector device can be designed in particular as an intermediate cover between the reflector devices.
  • the further reflector device can therefore be formed, for example, as a reflecting surface between the individual reflector devices.
  • the reflector devices and the light-emitting devices can be arranged particularly advantageously on a heat-dissipating device. In this way it is thus ensured that the heat generation occurring is kept within acceptable limits and thus the service life of the LEDs used in particular is not reduced.
  • the heat dissipating device may be a board or printed circuit board made of a heat-conducting material, in particular aluminum.
  • the light-emitting devices are arranged together with the reflector devices.
  • the reflector devices can have at least one fastening element by means of which they can be fastened in the region of the light-emitting devices (in particular LEDs) in a simple manner.
  • the fastening element may be at least one mounting foot provided with a latching device, in particular a latching hook or a latching lug, on the underside of the reflector device.
  • the fastening elements can also be provided, for example, with walls or fastening feet provided with end-side projecting elements, which can be inserted into corresponding openings in a printed circuit board, printed circuit board, etc. and latched therein.
  • the reflector devices are further advantageously dimensioned adapted to the dimensioning of the light-emitting devices.
  • the choice of the type of reflector device is advantageously adapted to the dimensioning of the light-emitting device in order to obtain an optimal light emission here. It can thus be done not only a dimensional adjustment, but in particular an adaptation to the respective output power of the light-emitting device. The aim is always to emit a large amount of light directed.
  • the light-emitting unit in several parts, wherein a power unit and a light-emitting devices and the reflector devices are designed to be separable from one another. Due to such separation capability, the power section may be fixedly secured to a wall or ceiling of a building or room, whereas the part comprising the light emitting devices and the reflector means may optionally be disconnected from the power section and replaced with a new one.
  • the light-emitting unit or, when forming a multi-part unit, the power unit may advantageously be provided with at least one fastening device for fastening to an object, in particular a wall or a ceiling of a room or building.
  • a particularly simple attachment to a building is possible.
  • already corresponding through holes for passing hooks or screws for connecting to a ceiling or wall of a building or Room be provided on the power unit.
  • an otherwise fastening device for example, for attachment to a pole, tree, etc., wherein an adaptation to the conditions of the surface to which the power unit is to be attached, can be made.
  • FIG. 1 shows a perspective view of an embodiment of a stationary light-emitting unit 1 in the form of a radiator, which is fixedly mounted on a wall 2.
  • the attachment takes place via a mounting bracket 10, which is provided with through openings 11, through which screws 12 engage for fastening to the wall 2.
  • the light-emitting unit 1 is pivotally attached to the mounting bracket 10. To achieve this pivoting is transverse to the U-shaped configuration of the mounting bracket 10 extending away from the wall 2, a pivot axis 13 is provided which passes through both the mounting bracket 10 and the housing 14 of the light-emitting unit.
  • the emission of the light-emitting unit 1 obliquely to a bottom, not shown, so directed obliquely downward with respect to the view shown.

  • FIG. 3 A frontal view of the front surface 15 and the wall 2 is in FIG. 3 shown.
  • the light-emitting unit 1 is provided with twelve light-emitting devices in the form of LEDs 3, which are each surrounded by reflector devices 4.
  • the twelve reflector devices 4 with centrally arranged LEDs 3 are arranged distributed with approximately the same distance from one another, in principle in the manner of a waffle pattern. As a result, a uniform emission of light via the front surface 15 of the light-emitting unit 1 is possible.
  • a cover plate 16 is also provided to the outer end of the housing 14, the in FIG. 2 is merely indicated.
  • FIG. 4 A detailed view of a circuit board 17 with the twelve LEDs and reflector devices arranged thereon is shown in a perspective view in FIG. 4 shown.
  • the board 17 is advantageously designed as a heat-dissipating device.
  • it consists of a good heat-conducting metal, such as aluminum.

  • the board 17 has a number of holes or openings 18 for the insertion of corresponding mounting feet of the reflector devices.
  • the openings 18 are in FIG. 4 only to be seen in part in the FIGS. 5 and 6 however also shown.
  • the mounting feet 40, 41 of the reflector devices 4 are best in the perspective view of the reflector device 4 from below in FIG. 8 to see.
  • the mounting feet 40, 41 have respective projecting lugs 42. As a result, they hold themselves firmly in the openings 18 of the board 17.
  • a subsequent removal or replacement of the reflector devices 4 is also possible, so unlatching and removing the reflector means 4.
  • the two opposite outer walls 43, 44 of the reflector means 4 are pressed slightly towards each other and thus the projecting lugs 42 from the Verrastungsposition moved out, so that a removal of the reflector devices 4 away from the board is possible.
  • spacer pins 45 are provided at two opposite corners, which provide a distance to the surface of the board 17 in the Verrastungsposition.
  • the lower edge 46 of the two opposite outer walls 47, 48 is in each case stepped, that is, the outer walls 47, 48 are not formed uniformly high, but higher in the area of the spacer pins 45 and lower in the remaining area.
  • a part of the two opposing outer walls 43, 44 is respectively formed lower than the area surrounding the two fixing feet 40, 41 and the corner portion of the spacer pins 45. This makes developing heat better be removed, so that it does not come under the reflector device to a heat accumulation.
  • the reflector device 4 also has a truncated pyramid in a respective angle to each other and surrounding the LED 3 surfaces 49, 50, 51, 52. These surfaces are arranged not only to each other, but also to the outer walls 43, 44, 47, 48 at an angle.
