Definitions

  • the invention relates to a vehicle lamp, having at least one light emitting window having a light emitting diode as a light source and at least one with a light entrance surface facing the light exit window optics for bundling the light emitted from the light emitting diode and a holding device for positioning the light emitting diode to the optics.
  • Such a vehicle lamp is known from WO 99/09349 A1. It has a light-emitting diode which is arranged on a carrier board together with an electrical circuit provided for its control and power supply.
  • the light-emitting diode has a convex light exit window, which faces the light entry surface of an optic. This bundles the light emitted by the light emitting diode in such a way that a predetermined light distribution is achieved.
  • a columnar projection is integrally formed on the optics, which is oriented with its longitudinal axis approximately at right angles to the plane of extension of the optics and passes through a hole provided in the light emitting diode.
  • the LED should be positioned by this measure on the optical axis of the optics.
  • the mounting of the LED on the optics is still relatively complicated, since the LED must be positioned in alignment with the perforations exactly to the columnar projections of the optics in the production of the vehicle lamp.
  • Unfavorable is also that the heat produced during operation of the light-emitting diode is dissipated only relatively poorly to the environment.
  • the vehicle lamp is therefore suitable only for light-emitting diodes with relatively low power.
  • the object is to provide a vehicle lamp of the type mentioned, in which the heat loss produced by the light emitting diode is well derived from the light emitting diode. In addition, it should allow the vehicle lamp in their production easy positioning of the LED on the optics.
  • the holding device has a housing with a first, the optics housing part and a second connected, designed as a cooling element housing part that between them Housing parts a receptacle for the light-emitting diode is formed, in which the light-emitting diode is arranged such that it rests with its side facing away from the light exit window surface on the second housing part, and that on the receptacle and / or the light emitting diode at least one centering element is provided for centering the light entry surface relative to the light exit window.
  • the light-emitting diode is arranged between two housing parts comprising this. Since the optics is connected to the first housing part, the light-emitting diode can be mounted in the manufacture of the vehicle lamp in a simple manner to the optics by the light-emitting diode inserted into the receptacle of the housing and the housing parts are then interconnected.
  • the at least one centering element provided on the receptacle and / or the light-emitting diode makes it possible for the light entry surface or the light emission point of the light-emitting diode to be centered in the connecting position of the housing parts relative to the light exit window.
  • the second housing part is designed as a cooling element with a low heat conduction resistance. This lies flat against the back of the light emitting diode and is thus connected to the light emitting diode with good thermal conductivity.
  • the cooling element may have on its outer side facing away from the LED outside a heat dissipation surface in contact with the ambient air, which is preferably larger than the surface of the light emitting diode. The heat generated during operation of the LED of this heat loss can thus be dissipated via the cooling element effectively to the environment.
  • cooling fins may be provided, whereby a comparatively large heat dissipation surface is made possible with compact dimensions of the second housing part.
  • a high-performance light-emitting diode can be provided, which provides a correspondingly large luminous flux.
  • the at least one centering element has at least one centering bevel, which extends transversely to the optical axis of the light emitting diode.
  • the LED is then centered automatically by means of the inclined surface when connecting the housing parts in the recording.
  • the housing parts may be formed as coupling parts of a plug-in coupling. The housing parts can then be connected to each other in the manufacture of the vehicle lamp by pushing one another in a simple manner.
  • the light-emitting diode has a preferably formed as a metal core board carrier plate on which a light-emitting semiconductor chip is arranged, wherein the carrier plate with its semiconductor chip facing the front surface of the semiconductor chip and with its back flat against the second housing part.
  • a light-emitting diode is commercially available as standard components cost.
  • the good heat-conducting carrier plate of these LEDs has a larger footprint than the semiconductor chip. As a result, a relatively large-area heat-conducting connection between the carrier plate and the second housing part is made possible.
  • the semiconductor chip is preferably arranged on the carrier plate in a housing, which can consist of a plastic casting compound, for example.
  • the light exit window has a convex light outcoupling surface, which preferably extends in a spherical surface arranged concentrically to the light emission point of the light emitting diode, if the light entry surface of the optic is concave and adapted to the light outcoupling surface, and if the receptacle for the light emitting diode is designed such that the light output surface comes into positive engagement with the light entry surface.
  • the light emitting diode is then centered when connecting the housing parts of the holding device directly to the concave light entry surface of the optics, which allows a particularly precise positioning of the light emitting diode to the optics.
  • the first housing part of the holding device has a releasably connectable to the second housing part, preferably designed as a cap part coupling element, said coupling element is preferably formed integrally with the optics.
  • the housing parts of the holding device can then be even easier and faster connected to each other in the manufacture of the vehicle lamp.
  • first and second housing part of the holding device are releasably connectable to each other, preferably by means of a latched in a connecting position bayonet connection.
  • the bayonet connection then allows easy and quick access to the light emitting diode in case of service.
  • the vehicle lamp on a lamp housing with an inner cavity, which has a light exit opening, which is covered by a lens, wherein in the inner cavity at least one socket for receiving the holding device is arranged.
  • the assembly consisting of the holding device with the housing parts and the light-emitting diode can then be completely pre-assembled in the production of the vehicle lamp and then easily inserted into the socket of the lamp housing.
  • the second housing part of the holding device is formed integrally with the lamp housing.
  • the number of components to be connected together is reduced accordingly.
  • a heat transfer surface between the second housing part and the lamp housing is avoided, so that the heat emitted by the LED heat loss can be better dissipated to the outside of the lamp housing.
  • an optical gel is arranged between the light exit window of the light emitting diode and the light entrance surface of the optical system whose optical refractive index corresponds approximately to the refractive index of the light exit window and the optics.
  • the optics is embodied as a light guide body, in which the light of the light-emitting diode coupled in through the light entry surface is guided by utilizing the total reflection at the boundary surfaces of the light guide body.
  • the coupled to the light entry surface in the light guide light of the light emitting diode can then be passed in the light guide largely lossless to a light exit surface.
  • a vehicle lamp has a non-illustrated in the drawing lamp housing with a closed inner cavity.
  • the luminaire housing has a light exit opening, which is covered by a lens.
  • a socket is arranged, in which a holding device, generally designated 1, is inserted, which has a receptacle for a light-emitting diode 2.

  • the light entry surface 6 faces a light exit window 8 of the light emitting diode 2 and the light exit surface 7 of the light disc.
  • the optic 5 is designed in such a way that a light distribution provided for the illumination function assigned to the light-emitting diode 2 is achieved in the emission region of the light exit surface 7.
  • the second housing part 4 of the holding device 1 is formed as a solid cooling element made of a metallic material. Between the first housing part 3 and the second housing part 4, the receptacle for the light-emitting diode 2 is formed. In Fig. 2 it can be seen that the receptacle in the second housing part 4 has an approximately cylindrical inner cavity into which a portion of the light emitting diode 2 is inserted.
  • the light-emitting diode 2 has an approximately circular disk-shaped metal core board 10, on which a light-emitting semiconductor chip not shown in the drawing is arranged, which is integrated in a light-emitting diode housing 11.
  • a light-emitting semiconductor chip not shown in the drawing is arranged, which is integrated in a light-emitting diode housing 11.
  • the light exit window 8 Arranged on the light-emitting diode housing 11 is the light exit window 8 which, with its rear side, faces a light emission point 12 of the semiconductor chip and has a light output surface 13 on its front side.
  • electrical connection contacts 14 are led out laterally, which are connected via bonding wires to power supply terminals of the semiconductor chip.
  • the terminal contacts 14 are connected via not shown in the drawing power supply lines to a drive circuit which is connected to the battery of the vehicle.
  • the light-emitting diode 2 is arranged in such a way in the receptacle of the holding device 1 that it rests with the side facing away from the semiconductor chip rear side of the metal core board 11 at the bottom of the receiving surface on the second housing part 4.
  • the front of the metal core board is flat against the semiconductor chip. Thereby, the heat generated by the semiconductor chip can be well dissipated to the environment.
  • the first housing part 3 has a coupling element 15 designed as a cap part. This is detachably connectable to a mating counter-coupling element 16 of the second housing part 4.
  • the coupling element 15 and the counter-coupling element 16 form a bayonet connection.
  • the counter-coupling element 16 has on its outer circumference three coupling projections 17 which engage in the locking position in each case an undercut of the coupling element 15. With the aid of a locking element 18, the bayonet connection is locked in the connecting position.
  • the locking element 18 is formed as a step or step, which is arranged on one of the coupling projections 17.
  • the coupling element 15 and the optics 5 are formed as an integral with each other injection molded part.
  • the coupling element 15 and the optics 5 are produced as separate parts and then connected together in particular by latching, gluing and / or welding.
  • the light output surface 13 of the light exit window 8 is convex and extends in a spherical surface, which is arranged concentrically to the light emitting point 12 of the light emitting diode 2.
