Definitions

  • the present invention relates to a light emitting device for a household appliance.
  • a household appliance light emitting device is from the US-A-3,228,288 known.
  • the object of the invention is to provide a household appliance light emitting device of the type mentioned, which is easy to manufacture and assemble.
  • a household appliance light emitting device solving this problem is described in claim 1.
  • the light condensing means generates a convergent or divergent bundle of light rays.
  • the light bundling device concentrates the rays emitted by a light-emitting diode into a bundle which has a substantially lower angular spectrum than the light emitted by the light-emitting diode
  • the light bundling device is preferably a light parallelizing device.
  • the light beam with the second angular spectrum is preferably a substantially parallel light beam.
  • the light beam having the second angular spectrum may have an aperture angle (ie, an angular deviation from parallelism) less than or equal to about ⁇ 10 °, about ⁇ 5 °, preferably less than or equal to ⁇ 2.5 °, more preferably about ⁇ 1 °, and most preferably less than equal to about ⁇ 0.5 °.
  • the intensity of the light beam can be 50% of the maximum intensity. This is due to the fact that the intensity of the light emitting diode at the edge of the first angle spectrum can amount to 50% of the maximum intensity. This depends on the definition of the angle spectrum or opening angle of the light-emitting diode.
  • the light divider can be spaced from the light bundling device without significant intensity losses occurring. Since the light beam with the second angular spectrum passes a distance between the light bundling device and the light divergence device, no coupling-in and coupling-out losses occur, as occur, for example, with optical fibers.
  • the light-emitting diode and the light-bundling device can be arranged close to a fixing region of the light-emitting device which is opposite to the light-diverging device. This has the advantage that no or only a few additional plastic and metal components are required in order to fix the light-emitting diode, for example, placed on a board on the mounting area.
  • the light emerging from the light-emitting diode is converted by the light bundling device into a light beam with the second, smaller and preferably parallel angular spectrum, which extends over a distance to the relatively distant light divergence device, where it is converted into a divergent light beam and exits from the light-emitting device.
  • the light divergence device is formed integrally with a housing.
  • the route may be without a light guide, in which the light beam extends with the second, smaller and preferably parallel angle spectrum.
  • the cross-sectional area of the light beam having a second angular spectrum may be larger than the luminous area of the chip of the light-emitting diode.
  • the light emitting diode comprises a lens, wherein the first angular spectrum of the light emerging from the light emitting diode has a range of about 20 ° to about 30 °, preferably about 50 ° to about 70 °, most preferably about 110 ° to about 130 °.
  • An angle spectrum can be defined such that the intensity of the light at the edge of the angle spectrum is about 50% of the maximum intensity.
  • a large angular spectrum of the light beam emitted by the light-emitting diode permits greater assembly tolerances between the light-bundling device, the light-emitting diode, the chip in the light-emitting diode, the lens in the light-emitting diode, the solder connection between the light-emitting diode and the circuit board, and between the circuit board and the fastening region the quality of the light beam with the second, smaller and preferably parallel angle spectrum is excessively impaired.
  • this light emitting device allows easy wiring because the board is located near the mounting area from which power is supplied to the light emitting device.
  • the light emitting diode is an SMD light emitting diode which is fixed on a circuit board by soldering.
  • the light-emitting device according to the invention is relatively tolerant of manufacturing tolerances.
  • SMD LEDs typically have a large angular spectrum, i. a large opening angle, between about 50 ° and about 120 °.
  • the second angular spectrum may be about ⁇ 15 °, preferably about ⁇ 10 °, more preferably about ⁇ 5 °, most preferably about ⁇ 1.5 °.
  • the household appliance light emitting device may comprise a plurality of light emitting diodes, wherein the light condensing device converts the light of the plurality of light emitting diodes into a light beam having the second, smaller and preferably parallel angular spectrum. This results in a particularly bright and / or a redundant light emitting device for a household appliance.
  • the light lobes of the light-emitting diodes preferably overlap when they impinge on the light-bundling device.
  • the light bundling device is a converging lens, in particular a Fresnel lens.
  • the light divergence device can be a scattering lens or a diffuser.
  • the distance between the light bundling device and the light divergence device may be greater than or equal to approximately 10 mm, preferably greater than or equal to approximately 20 mm, and most preferably greater than or equal to approximately 30 mm.
  • the cross section of the light beam having the second, smaller and preferably parallel angular spectrum is about 3 to about 20 mm, preferably about 5 to about 15 mm, most preferably about 8 to about 12 mm.
  • the angular spectrum of the divergent light beam exiting the light emitting device is about 25 ° to about 35 °, preferably about 40 ° to about 50 °, preferably about 50 ° to about 70 °, preferably about 80 ° to about 100 °, most preferably about 110 ° to about 130 °.
  • the light bundling device can be spatially fixed relative to the board. As a result, the tolerance chain described above for the light beam with the second, smaller and preferably parallel angle spectrum reduces to the Positional tolerance of the chip of the LED, the LED of the light emitting diode, the LED to the board and the board to Lichtbündelungs observed.
  • the light bundling device may be attached to the circuit board.
  • the circuit board can have recesses into which projections of the light bundling device engage.

  • the projections of the light bundling device may be arms. On the arms locking means may be formed.
  • the light-bundling device can be spatially fixed relative to a housing of the light-emitting diode, in particular in that the light-bundling device has a region which is complementary to the housing of the light-emitting diode and fixes the light-bundling device spatially relative to the light-emitting diode.
  • the light bundling device may have a housing which has a recess complementary to the housing of the LED at its region facing the printed circuit board.
  • the housing of the light concentrator can be positioned over the housing of the LED, and the housing of the LED spatially fixes the housing of the light concentrator.
  • the complementary region can rest against the entire housing of the light-emitting diode or it can rest only at four points or two corners on the housing of the light-emitting diode. As a result, the tolerances caused by the board can be eliminated.
  • the board may be arranged on the housing of the household appliance light emitting device so that the position of the board in the optical axis direction of the household appliance light emitting device and / or perpendicular to the optical axis direction of the household appliance light emitting device is determined by the housing of the household appliance light emitting device.
  • the position of the board and thus the position of the light emitting diode including the chip and the lens and the position of the light bundling device to the housing of the household appliance light emitting device can be relatively accurately determined.
  • the tolerances of the tolerance chain can be further reduced, resulting in a light output subject to relatively low copy scatters.
  • the housing of the household appliance light emitting device may have a first region with a first cross section and a second region with a second cross section, wherein the first region has a smaller cross section than the second region, a stepped transition between the first and second area is present, the board is set from the second area perpendicular to the optical axis of the household appliance light emitting device and the stepped transition determines the board in the optical axis direction.
  • the light divergence device is formed integrally with the housing of the household appliance light emitting device. This embodiment is particularly suitable for a casting process.
  • the board may be arranged on the lid.
  • the lid may be fastened to the housing, for example by means of a snap-in technique.
  • the lens may be disposed on the board as previously described.
  • size deviations of the board which may be, for example ⁇ 0.15 mm, can be compensated because the board is not applied to the housing. The size tolerance of the board can thus not lead to a jamming of the board in the housing, not to a deformation of the housing and not to a game of the board in the housing.
  • the light emitting device for a household appliance described below may be used to indicate to a user an operating state of the household appliance such as a washing machine, a dishwasher, a cooker, a refrigerator, and the like.

  • the angle spectrum of the light-emitting diode can be defined such that the intensity at the edge of the angle spectrum is 50% of the maximum intensity.
  • the condenser lens 6 operates as a light bundling device or light parallelizing device.
  • the converging lens 6 produces a substantially parallel light beam 8.
  • the intensity spectrum of the substantially parallel light beam may be defined such that the intensity at the edge of the angular spectrum is 50% of the maximum intensity.
  • This substantially parallel light beam 8 passes through the hollow housing 2.
  • the substantially parallel light beam 8 impinges on a light divergence device 4.

This results in a cost-effective manner a comparatively accurate alignment of the optical axis of the light emitting diode with the optical axis of the converging lens 6. This increases the quality of the light output of Haushals réellelichtabgabe worn.
  • FIG. 3 shows a broken section in the direction of the optical axis of the light emitting device through a part of the housing 2 and the circuit board 12 of the light emitting device.

  • the light-emitting device according to the invention has the advantage that it can be produced from a few parts, which can be produced inexpensively in a casting process. Furthermore, the light emitting device according to the invention is constructed so that the effects of manufacturing tolerances are minimized. Since the light-emitting diode 10 emits a light beam 18 with a relatively large aperture angle from the lens 16, the positional tolerance of the light emitting diode on the circuit board 12 and the positional tolerance of the circuit board 12 with respect to the housing 2 have only a relatively small effect on the quality of the light emitted by the light emitting device light beam.
  • the term position tolerance here also applies to a tilting of the light emitting diode 10, the board, the chip of the light emitting diode and / or the lens 16 of the light emitting diode. Due to the large opening angle of the emerging from the light emitting diode 10 light beam 18, the light emitting device is tolerant to tilting tolerances. Even with a tilting and / or displacement of the light-emitting diode 10, the circuit board 12 of the chip and / or the lens 16 of the light emitting diode, a sufficiently broad substantially parallel light beam is produced, which impinges on the light divider 4.
  • the condenser lens 6 does not necessarily have to generate a substantially parallel light beam.
  • the light beam generated by the condenser lens 6 may converge or diverge.
  • the light beam 22 generated by the divergence device 4 has a significantly greater divergence than the light beam 8 entering the divergence device 4.
