  • the second type of homogenizer 36 has a second radius of 0.15 mm to about 0.25 mm.
  • the homogenizing means 34 of the first type and the homogenizing means 36 of the second type may be arranged alternately to each other.
  • the opening angle of the light beam emerging from the homogenizing agent may be about 20 ° to about 60 °, preferably about 30 ° to about 50 °, most preferably 35 ° to about 50 °.
  • the light directing device 4 may have a diameter of about 10 mm to about 20 mm.
  • the converging lens 6 is secured to the board 12 by means of arms 24 with optional locking lugs (not shown).
  • the board 12 may have openings 34 (see FIG. 2 ), through which the arms 24 extend.
  • the circuit board 12 has an outer diameter corresponding to the inner diameter of the housing 2 of the light emitting device, so that the housing 2, the board 12 also defines in its position perpendicular to the optical axis of the light emitting device.
  • FIG. 2 shows a plan view of the board 12.
  • the light-emitting diode 10 is arranged on the board 12.
  • the board 12 has openings 34 through which an arm 24 can pass.
  • the converging lens 6 is thus aligned relatively accurately with the board 12.
  • the light-emitting diode 10 if an SMD LED is used, centered on the designated pads (pad). This results in a cost-effective manner, a relatively 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 the household appliance light emitting device.
  • 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 housing of the light emitting device has a first region 2a and a second region 2b.
  • the first region 2a has a smaller cross section than the second region 2b.
  • the cross section (perpendicular to the optical axis of the light emitting device) of the housing has a circular, elliptical, rectangular, polygonal shape.
  • the transition between the first region 2 a and the second region 2 b of the housing 2 is step-shaped.
  • the stepped transition determines the position of the board 12 in the direction of the optical axis of the light emitting device.
  • the inner diameter of the second region 2b defines the position of the circuit board 12 perpendicular to the optical axis of the light emitting device.
  • the light guide 4 is formed integrally with the first area 2a. Consequently, the housing 2 with the two areas 2a and 2b has no undercuts, so that it can be produced by a casting technique, for example by injection molding.
  • the inner diameter of the second region 2b allows a relatively accurate alignment of the circuit board 12 and thus the optical axis of the light-emitting diode 10 and the condenser lens 6, as previously with reference to FIG FIGS. 1 and 2 has been described.
  • the tolerance chain which results from the addition of the production and / or position tolerances of the light-directing device 4, the housing 2, the circuit board 12, the LED 10 including the chip and lens 16 to the circuit board and the converging lens 6 to the circuit board, can be reduced.

  • 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.
  • This embodiment has a simpler structure and can be easily mounted. In this embodiment, the wiring is easier to implement.
  • 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 directing device 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 light-directing device 4 can optionally have a significantly greater divergence than the light beam 8 entering the light-directing device 4.
  • Fig. 4 shows a home appliance seal assembly with a seal 70 and a household appliance light emitting device 50 which is arranged in a recess formed as a receptacle of the seal 70.
  • the recess in the seal 70 receives the light emitting diode 10 opposite portion of the housing 2 of the household appliance light emitting device 50.
  • the recess of the seal 70 thus accommodates the region of the housing 2 of the light-emitting device 50, in which the light-directing device 4 is located. Since the light-emitting diode 10 of the light-emitting device 50 is relatively far away from the seal 70, no or only relatively little heat generated by the light-emitting diode 10 is conducted into the seal 70. This can increase the life of the seal.
  • the housing 2 of the light-emitting device 50 may have at least one pointed sealing element 54 projecting away from the housing 2, which on the one hand fixes the light-emitting device 50 in its position relative to the seal and prevents a liquid from passing through the seal 70 in the region of the recess.
  • optional fasteners 60 are provided which fix the light emitting device 50 in position relative to a household appliance and / or dissipate heat generated by the LED.
  • the light emitting device is powered by a cable 52 with power.
  • Household appliance seal arrangement shown has a recess in the form of an opening in the seal 70.
  • the recess may also be formed as a blind hole, in which the light-emitting device 50 is arranged.
  • the entire seal 70 may be transparent or only the region of the recess and optionally its surroundings may be made transparent.
  • the term "receptacle” includes not only an opening or a blind hole in the seal 70. It is also possible to maintain the thickness of the seal 70 substantially constant and provide a receptacle on one side of the seal 70 which receives the light emitting diode 10 opposite portion of the housing 2 of the household appliance light emitting device 50. This receptacle may for example have a U-shaped cross-section. Also in this case, the seal must be formed semitransparent or transparent in the area of the recording, whereas it may not be transparent in an area remote from the recording.
