Definitions
- the invention relates to a light-guiding element for a laser vehicle headlamp, wherein the laser vehicle headlamp comprises at least one laser light source and at least one illuminable by the laser light source and thus excitable to the emission of visible light luminous element and the light guide is substantially arranged between the laser light source and the luminous element.
- the invention further relates to a vehicle headlamp with at least one laser light source and at least one, can be irradiated by the laser light source and thus excitable to the emission of visible light element.
- the light guide element has a light entrance surface and a Lichtaustrittsflä- surface, wherein the inlet cross-sectional area of the light entrance surface is greater than the exit cross-sectional area of the light exit surface and that radiated through the light entrance surface light over the the light entrance surface and the light exit surface connecting inner surface in the direction of the light exit surface is bundled.
- the invention allows the compensation of positioning errors of the luminous element with respect to the laser light source and ensures even with slight deviations that the irradiated laser light hits the luminous element and is not distracted uncontrolled or possibly endanger other road users.
- the in the assembled state of the laser light source facing the light entry surface is larger than the light exit surface and thus collects the incoming radiation, which are directed by the reflective inner surface to the light emitting element.
- both the high demands on the mounting of the luminous element relative to the laser light source can be reduced and thereby fulfilled, as well as the dimensional stability of the parts used in a laser vehicle headlamp during use (eg vibration load, resonance, strength, thermal expansion, ...) be ensured.
- the inner surface here designates the interior (or the one oriented in the direction of the light-guiding element interior) of the lateral surface between the light entry surface and the light exit surface.
- the light-guiding element has a substantially circular cross-section, that is, the light-entry surface has a larger diameter than the light-emitting surface.
- the light-guiding element preferably consists of a transparent material such as glass or plastic - the light-guiding element is embodied, for example, in one piece as a volumetric body, that is to say it consists of a material throughout.
- the reflective inner surface results in particular due to the total reflection at the interface light guide element environment.
- the acceptance angle of the light-guiding element is between 0 ° and 45 ° with respect to the optical axis of the light-guiding element.
- the light-guiding element is set up to reflect or concentrate light which impinges on the light entry surface at an angle of between 0 ° and 45 ° with respect to the optical axis, in the direction of the light exit surface.
- the light guide according to the invention allows high tolerances with respect to the positioning of the laser light source and the luminous element to each other.
- the reflective inner surface of the light-guiding element is designed essentially as a paraboloid or as a free-form surface.
- the formation as a paraboloid can in particular also take the form of a paraboloid of revolution. Depending on the exact application, the inner surface is thus shaped with the desired reflection properties.
- the outside of the light-guiding element in the region between the light-entry surface and the light-emitting surface is expediently provided at least in regions, but in particular completely, with an opaque coating. This can be prevented that light is emitted off the light exit surface of the light guide.
- the coating can be applied for example by painting or steaming.
- At least one receptacle for the luminous element is provided in the region of the light exit surface, wherein the receptacle is designed in particular as a blind hole or as a hollow completely surrounded by the light guide element.
- the lighting element can thus be arranged in the light guide. This has the advantage that during assembly, only the light guide element with respect to the laser light source must be accurately mounted - the optimal position of the light-emitting element is thus ensured at the same time, since the light-emitting element is held in the light guide.
- the lighting element can be replaced if necessary, the light guide can continue to be used.
- the light-emitting element can be protected from environmental influences.
- the luminous element is arranged in the mounted state "below" the light exit surface in the light guide.
- the light exit surface is at least partially covered by an opaque limiting element.
- This opaque limiting element may for example be designed as a coating in the form of painting or vapor deposition, but it may also be a separate component glued or otherwise applied.
- This limiting element (possibly in conjunction with a free-form reflector surface - see below) can be used to produce a dipped beam with a sharp light-dark transition.
- At least one reflector element extending around the light guide element is arranged between the light entry surface and the light exit surface, preferably in the area of the light exit surface, for deflecting the light emitted by the light element in a direction away from the light entry surface.
- the light emitted by the luminous element can be used photometrically - e.g. in connection with the above-mentioned limiting element for the realization of a low beam.
- a reflector element is advantageous because, for example, when using the light-guiding element in a vehicle headlight, the light emitted by the light-emitting element can be optimally directed into a main reflector of the vehicle headlight. At the same time an uncontrolled leakage of light from the headlight is prevented, or a better utilization of the light emitted by the light emitting element possible.
- the object of the invention is further achieved by an aforementioned vehicle headlamp according to the invention in that between the laser light source and the luminous element is arranged at least one light guide element as described above.
- the laser light source is arranged in the main emission direction of the vehicle headlamp in front of the luminous element, so that the light of the laser light source is emitted counter to the main emission direction of the vehicle headlamp.
- the risk of uninvolved road users by the laser beam is prevented when it comes to a malfunction of the headlight - because the laser beam runs counter to the main beam direction, he can not radiate uncontrolled from the headlight.
- the invention allows the realization of a vehicle headlamp, which can meet the legal requirements such as ECE, SAE, CCC, etc.
- At least one diaphragm element is provided, with which light reflected from the light entry surface of the light guide element or from the interior of the light guide element in the main emission direction of the vehicle headlamp can be shielded.
- the diaphragm element is designed as a connecting piece running between the laser light source and the light-guiding element, which is designed in particular as a tubular or semi-tubular shape.
- the radiation can be prevented in particular from laser light in the direction outside of the vehicle headlight.
- the diaphragm element can be coated, for example, with an anti-reflective or absorbent coating, or it can surround the relevant regions of the light-guiding element.
- FIG. 1 shows a cross-sectional view of a first variant of the light-guiding element according to the invention
- FIG. 2 shows a cross-sectional view of a second variant of the light-guiding element according to the invention
- FIG. 3 shows a cross-sectional view of a third variant of the light-guiding element according to the invention.
- FIG. 4 shows a cross-sectional view of a vehicle headlight with a light-guiding element according to the invention.
- a first variant of the light-guiding element 1 is shown.
- the light-guiding element 1 is used, for example, in a laser vehicle headlight 2 (see FIG. 4), between a laser light source 3 and a light-emitting element 4, which emits light emitted by the laser light source 3 for emission of visible light, in particular white color is stimulated.
- the light guide 1 has a light entrance surface 5 and a light exit surface 6.
- the inlet cross-sectional area of the light entry surface 5 is greater than the exit cross-sectional area of the light exit surface 6 - if, for example, as in the present embodiment, the light guide 1 has a substantially circular cross-section, so the entrance surface radius 50 is greater than the exit surface radius 60th
- Light incident under this acceptance angle range (that is, between 0 ° and 45 °) is converged toward the light exit surface 6.
- Light incident at an angle greater than the acceptance angle is either reflected directly at the light entry surface 5 or enters the light guide element 1, but is then reflected back and forth so that it exits again at the light entrance surface 5 and not the light exit surface 6 reached.
- the inner surface 7 of the light-guiding element 1 is designed essentially as a paraboloid or as a free-form surface. Furthermore can, as shown in Fig. 1, the outside of the light guide 1 in the region between the light entrance surface 5 and the light exit surface 6 with an opaque and / or reflective coating 8 may be provided. This coating 8 may cover the specified area in areas or even completely.
- a receptacle for a luminous element 4 is provided in the area of the light exit surface 6, a receptacle for a luminous element 4 is provided.
- the receptacle for the luminous element 4 is designed as a blind hole 9
- the variant in Fig. 2 provides a completely surrounded by the light guide 1 cavity 10 before.
- the mentioned light-dark transition can be favored by the illustrated in Fig. 3 variant of the light guide 1 according to the invention:
- the light guide 1 has a running around the light guide 1 reflector element 11, which emits the light emitted by the light emitting element 4 in one of deflects the light entrance surface 5 facing away.
- the reflector element 11 is designed for example as a half-shell (only the upper or lower half is present) or as a full reflector.
- the reflector element 11 is to be arranged between the light entrance 5 and the light exit surface 6, but is preferably located, as in the present exemplary embodiment, in the region of the light exit surface 6.
- Fig. 4 is finally a vehicle headlight 2 in a sectional view in cross-section to see in which an inventive light-guiding element 1 is used. Only the essential features for the understanding of the invention are shown, since those skilled in the other elements of a vehicle headlamp are known.
- the vehicle headlight 2 comprises a laser light source 3, which, for example, in a wavelength range between 200 nm and 450 nm, ie partially in the non-visible UV Area, radiates.
- the radiated power of the laser light source 3 is between 0.5 and 2 W, but may be higher.
- the laser light source 3 is, for example, a semiconductor laser in the form of a laser diode. It is also possible to provide a plurality of laser light sources 3, for example in the form of laser diode arrays.
- the luminous element 4 is arranged on the optical axis 400 of the vehicle headlight 2 in a focal point of the reflector 16.
- the reflector 16 may also be designed as an open-space reflector with a plurality of different focal points, wherein according to the illustrated embodiment, the luminous element 4 is arranged precisely in one of these focal points.
- the vehicle headlight 2 is closed by a cover 17.
- the cover 17 may be configured as desired, but is preferably largely transparent.
- the desired light pattern of the vehicle headlight 2 is generated by the light guide element 1, the luminous element 4 arranged therein and the reflector 16.
- the light guide 1 according to the invention allows greater tolerances with respect to the relative positioning between the laser light source 3 and light element 4, for example when the light source 3 is replaced due to repair or if the laser light source 3 is no longer in optimal position due to vibrations during operation.
- a support member 18 is provided - the support member 18 is here provided with cooling fins 19, which serve to derive the resulting in the light generation in the light element 4 and the light guide 1 heat.
- the cooling fins 19 are just one example of heat sinks that can be used here - a number of possibilities are known to those skilled in the art in this regard, so will not be discussed in detail here.
- the laser light source 3 and the luminous element 4 are arranged so that the light of the laser light source 3 is emitted against the main emission direction 200 of the vehicle headlamp 2.
- the laser light source 3 is thus arranged in the main emission direction 200 of the vehicle headlamp 2 in front of the luminous element 4, so that the light of the laser light source 3 is emitted counter to the main emission direction 200 of the vehicle headlamp 2.
- the beam direction 500 of the laser light source 3 thus runs opposite to the Main emission direction 200 of the vehicle headlight 2. This prevents that in the event of damage to the vehicle headlight 2 or a malfunction, the light of the laser light source 3 escape and may endanger other road users.
- the beam direction 500 of the laser light source 3 preferably extends at an acute angle to the main emission direction 200 of the vehicle headlight 2.
- the angle can therefore be between 0 ° and 90 °.
- An angle of 0 ° thus means that the laser light source 3 is arranged on the optical axis of the vehicle headlight 2 in the main beam direction 200 behind the light-emitting element 4.
- an angle of 90 ° means that the beam direction 500 of the laser light source 3 is normal to the optical axis of the vehicle headlight 2.
- Optical axis and main emission direction 200 of the vehicle headlight 2 are substantially parallel to each other.
- light source 3 and light-guiding element 1 or light-emitting element 4 can be arranged relative to one another.
- an optical element in the form of a collecting lens element 20 is arranged immediately after the laser light source 3. This converging lens concentrates the light of the laser light source 3 in the direction of the light-guiding element 1 or of the luminous element 4 arranged therein.
- any other optical elements may also be used, for example lenses and / or prisms of various kinds.
- absorbing elements are arranged around such optical or light-guiding elements 1 in order to prevent any reflections of the incoming laser light in the main emission direction 200 of the vehicle headlight 2 and thus endanger other road users.
- the diaphragm element 21 in FIG. 4 represents an embodiment of such elements. It prevents radiation of reflections from the vehicle headlight 2 out.
- the said optical, light-guiding elements 1 and absorbing elements such as the diaphragm element 21 may also be provided with anti-reflective surfaces or be designed so that they only reflect or absorb light in the wavelength range of the laser light, but translucent for visible light are executed and thus have a look at the headlight components allow. In this case, irregularities such as inclusions or microstructures can be provided, which deflect the laser light, make visible from the outside and thus serve as a design element.
- the diaphragm element 21 in FIG. 4 is arranged above a horizontal plane extending through the optical axis 400 of the vehicle headlight 2 between the light guide element 1 and the cover plate 17.
- the light functions of the vehicle headlamp 2 are not adversely affected.
- the diaphragm element 21 can also be designed such that it covers the entire free-jet region of the laser light, for example in the form of a tube or a tube with a semicircular cross-section ("half-pipe"). In a further variant, it can be made semi-mirrored and / or for design reasons be illuminated with its own light source (eg a blue LED) Such variants are not shown in the figures.
- the invention according to the above embodiments allows the realization of a vehicle headlamp, which can meet the legal requirements such as ECE, SAE, CCC, etc.
- the waste heat generated during operation of the laser light source 3 can also be used.
- the laser light source 3 is arranged close to the cover plate 17 below a horizontal plane running through the optical axis 400 of the vehicle headlight 2 in the installed state of the vehicle headlight 2.
- the horizontal plane in FIG. 4 runs normally onto the plane of the drawing through the optical axis 400 of the vehicle headlight 2.
- the laser light source 3 is arranged so close to the cover plate 17 that the cover plate 17 can be heated by means of the waste heat of the laser light source 3.
- the waste heat can be used for defrosting and deicing the cover 17.
- the ventilation device 13 of the laser light source 3 can here by controlling the waste heat flow under supporting be used.
- the laser light source 3 is positioned below a design aperture element 22 which has corresponding design aperture openings 23 for the passage of the waste heat.
- these design aperture openings 23 can have a nozzle-like shape, so that the airflow 24 caused by the waste heat of the laser light source 3 can be directed in a targeted manner.
- nozzle-like shape is here to be understood a shape that allows the steering of the air passing through the design aperture openings 23 air flow to meet the above-mentioned object.
