Definitions
- the invention relates to a vehicle lamp with at least a first and a second partial emitter body, which are in a spatial relationship and are each aligned in a first direction of emission and a second direction of emission, with a common housing for the two partial emitter bodies and with a holder for attaching of the common housing on a vehicle frame, the spatial connection of the two emitting parts being represented by the common housing, the common housing having a height, a length arranged perpendicularly to the height and a depth arranged perpendicularly to the height and perpendicularly to the length has a directional component parallel to the two emission directions and wherein each of the two partial emission bodies has a circumferential emission surface edge perpendicular to its emission direction.
- DE 103 51 048 A1 built-in vehicle headlights which have a reflector with an elongated light decoupling element adjacent thereto.
- Two emitting parts, one round and one rectangular, can be defined here, with the corresponding built-in vehicle headlight not being fastened to the vehicle via a holder of a housing but being built into it.
- DE 10 2018 213 317 A1 also discloses a lamp to be installed in a vehicle with two emitting parts.
- Headlights are only arranged in the front area of a vehicle. In addition to road safety by making the vehicle visible to other road users, they are used in particular to illuminate the road ahead of the vehicle in the form of low beam, fog light, high beam or any other suitable light distribution in order to improve the driver's view. Headlights can have at least one incandescent lamp, gas discharge lamp or semiconductor light source, for example a light-emitting diode, as the light source. It is possible for a headlight to be able to generate different light distributions by means of one or more light modules arranged in it.
- Headlights can work according to a reflection principle, with light emitted by a light source being reflected by a reflector onto the roadway in front of the vehicle equipped with the headlight in order to produce a desired light distribution.
- headlights also work according to a projection principle, whereby the light bundled by a primary optic, for example a reflector or an attachment optic with totally reflecting properties, is projected through a secondary optic, for example a projection lens, to generate the desired light distribution onto the roadway in front of the vehicle.
- Vehicle lights are mainly used for road safety by making the vehicle visible to other road users.
- front lights in the front area of the vehicle are used as position lights, flashing lights or daytime running lights
- rear lights in the rear area of the vehicle are used, for example, as brake lights, rear lights, flashing lights, position lights or reversing lights.
- Lights arranged on the side of the vehicle serve, for example, as side marker lights.
- the front lights can be integrated into the headlight or be designed as a separate light on the motor vehicle.
- Luminaires can fulfill one or more lighting functions. Luminaires usually have incandescent lamps or semiconductor light sources, for example light-emitting diodes, as light sources.
- White light sources are required to implement the daytime running light, position light and main beam in the front area of the vehicle and to implement the reversing light in the rear area of the vehicle.
- the flashing light in the front or rear area is realized with yellow, orange or amber light sources or with appropriately colored color filters.
- the brake light and rear light in the rear area are realized by red light sources or by appropriately colored color filters.
- the invention is based on the basic knowledge that the compactly designed emitter body offers a calm pole, while the narrow and long emitter body acts aggressively, which, in combination with a housing shape that emphasizes these opposites, increases attention.
- a vehicle lamp with at least a first and a second partial emitter body which are in a spatial relationship and are each aligned in a first emission direction and a second emission direction, can be combined with a common housing for the two emitting parts and with a holder for attaching the common housing to a vehicle frame, in which the spatial relationship of the two emitting parts is represented by the common housing, the common housing has a height, a length arranged perpendicularly to the height and a depth arranged perpendicularly to the height and perpendicularly to the length with a directional component parallel to the two emission directions and each of the two partial emission bodies has a circumferential emission surface edge perpendicular to its emission direction that the partial emitter body is compact perpendicular to the first direction of emission and the second partial emitter body perpendicular to the second direction of emission is narrow and long along the length and the common housing viewed against the respective direction of emission on one of the two partial emitter bodies
- a "vehicle light” is preferably a device in which a light source is permanently installed or in which a light source can be installed or used and which serves to make the vehicle visible to other road users. These include in particular position lights, rear lights, turn signals, daytime running lights and brake lights and combinations thereof.
- a "bulb” can be understood to mean any electrical equipment and/or any electrical consumer that is set up to generate light.
- these include incandescent lamps or semiconductor light sources.
- a “radiating surface” is understood to mean, in particular, a surface of a vehicle light from which the light emitted by the vehicle light is emitted.
- a “radiating body” is then correspondingly understood to mean a body which has the radiating surface.
- an emitter can be made of a material that is essentially transparent to light.
- the radiating surface can be curved or flat or even, depending on the requirements, in particular for lateral visibility or visibility from different heights.
- the radiating surface can be arranged or aligned inclined in relation to the direction of travel of the vehicle or in relation to the horizon or in relation to the horizontal.
- the emitter can in particular have optical elements in order to suitably shape, direct, reflect or deflect the light to be emitted.
- optical elements can also be provided in addition or instead, in particular inside the housing, possibly even outside it, in order to suitably shape, direct, reflect or deflect the light to be emitted.
- a “partial emitting body” can be understood as merely part of a emitting body if this is formed, for example, from a plurality of, in particular from at least two, emitting part bodies. Different functionalities of the same are preferably assigned to different partial emission bodies of a vehicle light, but this does not necessarily have to be the case. Depending on the presence of partial emission bodies, partial emission surfaces can then also be defined for a vehicle light, which together form the emission surface and can each be represented by an associated partial emission body.
- One illuminant or several illuminants can radiate through the emitter or emitter.
- a "radiation direction” is preferably understood to mean the direction in which the highest light intensity is emitted by the vehicle light. Inside the vehicle light, the direction of emission can be defined as the vectorial sum of all light paths, which—naturally—can still experience changes in direction during their passage from the illuminant(s) to the emission surface. It goes without saying that when partial emitting bodies or partial emitting surfaces are provided, respectively associated directions of emission of the respective partial emitting bodies or partial emitting surfaces can be provided, which in particular can deviate from one another.
- each of the two emitter bodies can be assigned its own emission direction, so that the vehicle light can comprise two or more emission directions.
- the emission directions can also be aligned parallel to one another.
- the emission directions have at least a predominant component in the direction of travel for vehicle lights that shine in the direction of travel or opposite to the direction of travel for vehicle lights that shine in the reverse direction, if the Vehicle lights are attached to a vehicle or to the vehicle frame.
- a predominant component of the emission direction of the corresponding vehicle light is directed in a corresponding lateral direction.
- the emission directions are each aligned horizontally in order to ensure good visibility in as many driving situations as possible.
- a vehicle light with at least a first and a second emitter body, which are spatially related and are each aligned in a first emission direction and a second emission direction, with a common housing for the two emitter bodies and with a Holder for attaching the common housing to a vehicle frame, in which the spatial connection of the two emitting parts is represented by the common housing, in which the common housing has a height, perpendicular to the height and a length perpendicular to the height and perpendicular to the Length-arranged depth with a direction component parallel to the two emission directions and in which each of the two emitting parts has a peripheral emitting surface edge perpendicular to its emission direction, also characterized in that the emitting part is perpendicular to the first Emission direction compact and the second emitter body perpendicular to the second emission direction along the length are narrow and long and the common housing, starting from a maximum height of the common housing already explained above, in the form of a wing and/or an aero
- the above design also ensures a large surface area, which promotes cooling of the housing and thus of the entire vehicle light.
- wing refers to a basic form that originates essentially from the animal world but also from aircraft technology, which on the one hand is intended to give the ability to fly and on the other hand usually against the direction of flight seen from a compact body extending long and narrow in a longitudinal direction.
- a “wing” can also be understood to mean a wing.
- This is preferably known as a component of a vehicle whose main task is to generate dynamic lift.
- the function of the hydrofoil can be to generate a sufficiently large force perpendicular to the direction of flow by influencing the flow around it. This force is the lift that keeps an airplane in the air or lifts a hydrofoil out of the water.
- a corresponding shape of the housing of the vehicle lamp can be used.
- the mechanism of action of the wings is part of the induced air resistance: it withdraws the energy required for this from the flow system that supplies lift in the form of flow resistance. In principle, this part of the induced air resistance cannot be eliminated, since it physically takes into account the law of conservation of energy and momentum.
- induced drag is mainly caused by edge vortices at the wing tips: here a pressure equalization occurs between overpressure under the wing and underpressure over the wing. This creates an edge vortex around the longitudinal axis of the aircraft at each wing tip, the kinetic energy of which is withdrawn from the flow system that generates lift and is thus lost unused.
- the tip vortices can be reduced by a high aspect ratio, which means the ratio of the wingspan to the average flight depth, but in principle cannot be completely eliminated with a number of wings.
- Aerodynamics is preferably understood as a part of fluid dynamics and describes the behavior of bodies in air or compressible gases, the latter also being referred to as gas dynamics.
- the second area of fluid dynamics, hydrodynamics deals with liquids. Aerodynamics describes the forces, such as the dynamic Buoyancy that enables, for example, airplanes to fly or sailing ships to sail through water with the help of the wind.
- Many other areas of technology, such as civil engineering or vehicle construction, have to deal with aerodynamics.
- the "aerodynamic cross-section” expresses a cross-section with particular aerodynamic properties that comes from the field of aerodynamics.
- the basic shapes explained above are preferably arranged in such a way that the radiation directions coincide at least in one component, preferably even completely, with the direction of flight of the corresponding body or with a direction opposite to the direction of flow around the corresponding body.
- a vehicle lamp with at least a first and a second partial emitter body which are in a spatial relationship and are each aligned in a first emission direction and a second emission direction, can be combined with a common housing for the two partial emitter bodies and with a holder for attaching the common housing to a vehicle frame, the spatial connection of the two partial emitter bodies being represented by the common housing, the common housing having a height, a length arranged perpendicularly to the height and a length perpendicular to the Height and depth arranged perpendicularly to the length with a directional component parallel to the two emission directions and wherein each of the two radiating part bodies has a circumferential radiating surface edge perpendicular to its radiating direction, characterized in that the first radiating part The body perpendicular to the first emission direction is compact and the second partial emission body perpendicular to the second emission direction is narrow and long along the length and the common housing along at least 90% of the length of the
- the relatively high depth also leaves sufficient installation space, although the housing, especially in the area of the long and narrow emitter body, can be made correspondingly narrow in order to draw the viewer's attention to the To steer radiating body.
- the A relatively large depth also enables the housing to have a relatively large surface area, which can promote cooling of the housing or the vehicle light.
- the compactly designed radiating part body can each offer a stationary pole.
- the narrow and long radiating part body can then appear aggressive, which in combination increases the attention.
- attention can then be maximized in accordance with the basic idea explained above.
- the compact first partial emitter body is arranged in an area of the housing, the wing or the wing that has a high height, while the narrow and long second partial emitter body is arranged in an area of the housing that is opposite has a lower height.
- the height, depth and length of the housing can be defined in particular starting from the narrow and long radiating part body to be formed along the length. The depth is then perpendicular to the length with a directional component to the respective emission direction.
- the depth of the housing does not necessarily have to be aligned parallel to the respective emission direction, as long as a directional component of the depth can be found parallel to the respective emission direction.
- a predominant directional component is preferably aligned parallel to the respective emission direction, so that the depth does not deviate from the respective emission direction by more than 45°.
- the case for example when it approaches the shape of a wing, can have lengths, depths and heights that are not found on planes but on curved but correspondingly linearly independent surfaces, these surfaces possibly even their curvature vary in space.
- Such configurations can be found, for example, when the narrow and long second partial emitting body has a curved or kinked emitting surface, which may be desirable for design reasons.
- depths and heights can be defined in each case linearly independently of the length.
- the length, depth and height of the housing will differ based on the general geometric alignment of the same in relation to the narrow and long second emitter body and its emitting surface or in relation to the bracket and the arrangement of the narrow and long second emitter body and whose radiating surface to this holder result in accordance with the known understandings of height, length and depth.
- a cross-section is then correspondingly defined in a plane defined by the height and depth.
- a cross section can also be determined or defined in a plane defined by the direction of travel of the corresponding vehicle or by the radiation directions on the one hand and by the height.
- the direction of emission and the depth deviate from each other by less than 20°, in particular less than 10°, preferably less than 7°.
- the vehicle light can then be aligned horizontally or vertically in or opposite to the direction of travel.
- an alignment perpendicular to the direction of travel can also be provided.
- the length can then be arranged horizontally and the height vertically, or vice versa.
- the second partial emitting body is used as a flashing light, it makes sense to align the length essentially horizontally.
- the direction of emission and therefore the depth of the housing is preferably always aligned essentially horizontally in order to ensure visibility over a large distance.
- the compact first partial emitter body is arranged in a higher area of the housing and the narrow and long second partial emitter body is arranged in an area of the housing that is lower in terms of height.
- the housing particularly emphasizes the different characteristics of the respective radiating part bodies.
- a “housing” can be understood here as a solid shell of the vehicle light, which protectively surrounds a light source and any electrical or electronic or other functional assemblies that may be provided and protects this or these from the environment.
- the housing can protect the illuminant or illuminants of the vehicle light from the effects of the weather, mechanical influences and the like.
- other assemblies such as electrical components, but also optically effective assemblies, heat dissipation and the like can be provided in the housing.
- the housing is preferably closed by the radiating body or bodies, in which case it can optionally also have further openings, for example cable openings, through a holder or the like.
- the housing protects the radiating body or bodies, possibly together with a holder within the housing, from the effects of the weather and unintentional mechanical damage, so that other vehicle parts in particular, such as for example and in particular its body, do not provide any protection or additional protection must be provided.
- the common housing is formed in one piece, resulting in a structurally simple implementation is given.
- a non-integral object describes, for example, an object that has been joined, formed together, and/or assembled in some other way from at least two objects.
- An object can preferably be formed in one piece, for example by rapid prototyping methods or by casting.
- the housing can include a bracket with which it, and thus also the vehicle light, can be attached to a vehicle.
- a “mount” is preferably understood to be any device that is set up to mechanically connect the or a housing of a vehicle light or the vehicle light directly or indirectly to the vehicle. If necessary, supply lines can be led into the housing through or to the holder.
- the common housing is attached or attachable to a vehicle frame by means of a holding arm of the bracket. This increases the aggressive effect of the narrow and long radiator.
- the holding arm can also be designed in one piece with the housing and is then part of the housing.
- a "retaining arm” can preferably be understood as any mechanical and arm-like connection of the housing of the vehicle light to the vehicle, whereby this can ultimately be designed differently.
- a holding arm will be characterized by an area that has a smaller cross section than the housing or a symmetrical, that is, for example, elliptical, circular, rectangular or square cross section.
- retaining arms can be made very short or even extend over more than the length of the remaining housing of the vehicle light.
- the length of the housing can be defined parallel to the extent of the holding arm, which then, starting from the holding arm and taking into account the radiating surfaces, a definition of the height, essentially parallel to the radiating surface or surfaces, and the Depth, are used essentially perpendicular to the radiating surface or the radiating surfaces or with a component parallel to the respective radiating directions.
- the attention to a vehicle lamp can be maximized if the compact first partial emitter body is arranged closer to the holding arm, at least on average, preferably entirely, than the narrow and long second partial emitter body.
- a particularly stable arrangement cannot be achieved if the holding arm merges into the housing, in particular without a kink or with only a smooth transition.
- the load-bearing part of vehicles can be referred to as “vehicle frame”.
- Load-bearing parts have the function of supporting the drive, the body and the payload and of stabilizing them against external forces.
- the chassis can be part of the vehicle frame or essentially represent it.
- the body In vehicles with a self-supporting body, the body is the supporting element and thus at the same time the vehicle frame or part of the vehicle frame.
- the wheel suspension, all essential drive elements such as transmission and engine, possibly the body or cargo containers and trailer hitches can be attached to the chassis. Chassis with built-in running gear and drive train can also be roadworthy without a body.
- the emitting parts can be inserted into the common housing.
- the common housing has a streamlined cross section in each case in sectional planes aligned parallel to the depth and to the height through the housing.
- the vehicle light provides as little air resistance as possible and a low level of noise, for example from the wind.
- the resulting laminar flow apparently also enables good heat dissipation.
- a “streamlined shape” can preferably be understood as the ideal shape of a body that is characterized by the lowest possible flow resistance to the medium flowing around it, mostly air or water.
- a quantitative measure of the streamlining is, for example, the drag coefficient C w - this is only dependent on the shape and not on the size of the body flowing around it in a first approximation. The lower its C w value, the more streamlined the body.
- Streamline shape can be qualitatively read from a smooth, largely turbulence-free course of the streamlines, which can be made visible in numerical simulations or in wind tunnel experiments.
- Two straight lines are given by a firmly defined direction of depth and by a firmly defined direction of height. Two straight lines can create a plane be determined mathematically. A section plane mentioned above can thus, as described above, be clearly defined by the depth and the height.
- the common housing can also be designed in the form of a wing, starting from the holder, in order to provide good cooling of the vehicle lamp.
- the arrangement also makes it possible, as already indicated above, to further maximize attention, particularly when a holding arm is used.
- the common housing can each have a greater depth than height, starting from the holder along the edges of the common housing. The latter makes it possible in particular for the radiation bodies to come into their own in the housing.
- the common housing seen against at least one of the two emission directions, can taper from the maximum height of the common housing to the holder in order to also be able to provide good cooling of the vehicle light, especially when a holding arm is used.
- the compact first partial emission body preferably has an associated emission surface that is correspondingly compact, while preferably the narrow and long second partial emission body has an associated partial emission surface that is correspondingly narrow and long.
- the compact first partial radiating body or its associated correspondingly compact radiating surface can be arranged in a thicker area of the wing, in particular, for example, also at its root or attachment, while the narrow and long second partial radiating body or its associated correspondingly narrow and long radiating surface can be arranged in particular in a long and narrow area of the wing. This then requires a design of the vehicle light that maximizes attention.
- the ratio between depth and height can be smaller, possibly also significantly, than in the area of the long and narrow second partial emitter body, which can also result in a design of the vehicle light that maximizes attention.
- the depth of the common housing is at least twice the height of the common housing, whereby good cooling of the vehicle lamp can also be achieved.
- a front and/or rear side of the common housing preferably has a rectilinear region, with the front and rear sides particularly preferably each having a rectilinear region and the two rectilinear regions approaching each other, starting from the holder along the length .
- the vehicle lamp can be designed as aerodynamically as possible with the advantages already mentioned above.
- the "overhang of the housing” can be defined in particular as the area of the housing that goes beyond or protrudes or protrudes in depth beyond the area of the connection between the housing and the respective radiating surface.
- the housing projection is in particular the housing areas, which can then still be seen in the direction of the height above or below the radiating part body or the radiating surface.
- the housing protrusion in the cross section perpendicular to the length can be smaller than the height of the associated radiating part body in this cross section in order to maximize attention, since this allows a relatively small housing protrusion in the height, so that the radiating part body and in particular its associated radiating surface clearly in the foreground.
- a streamlined configuration or good cooling of the vehicle lamp can also be achieved as a result.
- the housing projection can taper in a tapering area along the length pointing away from the holder.
- radiating surface edge is understood to mean, in particular, the edge of a respective radiating surface that delimits the radiating surface on the outside. Depending on the specific configuration, each partial emission surface can also be assigned a corresponding emission surface edge, which rests at least partially on the housing. [65] In particular, a peripheral emission surface edge has a maximum diameter and a minimum diameter. Only with circular radiating surfaces are the maximum and minimum diameters the same, which then also applies to the radiating surface itself. Particularly in the case of curved radiating surfaces, it seems advantageous to leave the cross-section lines for determining the maximum or minimum diameter on the radiating surface in order to be able to record the geometry of the radiating surface well in this way.
- the spatial relationship between the two partial emitter bodies is represented by the fact that the two partial emitter bodies are spaced apart from one another by less than the maximum diameter of the edge of the radiating surface of the compact first partial emitter body, preferably less than half its maximum diameter.
- this can represent the above-mentioned contrast between compact on the one hand and narrow and long on the other hand in a good technical way and thus attract attention with a corresponding housing shape, the latter particularly applying at a distance of half the maximum diameter or less.
- the two partial radiating bodies preferably merge into one another or directly adjoin one another. This has the advantage that the contrast between compact on the one hand and narrow and long on the other hand can be implemented even better.
- a structure that is as compact as possible can also be provided, which—depending on the specific implementation—can allow short distances for electrical lines and the like.
- the emitting surface edge of one emitting sub-body will reach the emitting surface edge of the other emitting sub-body in the area in which they directly adjoin one another. In this area, in particular, there can generally not be any contact between the two radiating surface edges and the housing.
- an adhesive or a sealant can be provided here, which is arranged between the two radiating surface edges in this area. It is also conceivable to connect or seal the partial radiating bodies in the direction of the interior of the housing behind the two radiating surface edges.
- the latter can be accepted if a seam when assembling the two partial radiating bodies can be minimized or completely avoided or healed.
- the partial radiating bodies are then used for identical functionalities, this appears to be uncritical anyway.
- a jump of light can be minimized in such a way that it can be accepted even if there is no seam.
- the latter applies in particular if the two partial radiating bodies are manufactured in one piece from the outset, i.e. for example in a common primary shaping process or from a semi-finished product that is primary shaped as a whole.
- a "merging" of the two partial radiating bodies can be implemented in particular by the fact that they are designed in one piece. This enables them to be manufactured easily, since they can then be shaped in one production step and also mounted in the housing.
- the two radiating surface edges can merge into one another in a discontinuous manner in order to draw a lot of attention.
- a “discontinuous transition” is understood to mean a transition that is continuous but has a discontinuous change in direction, for example with a sharp bend or with another sharp transition between the two edges of the emission surface.
- the two radiating surface edges can also merge into one another with a change of direction in order to draw a lot of attention.
- a change of direction is meant in particular, for example, a change from circular to straight, or from one circular shape to another circular shape, possibly with opposite radii and then to a straight line.
- this change of direction can be discontinuous, for example due to a sharp bend, but also as something softer transition be formed. It can be assumed that - the softer this transition occurs - the less attention is generated.
- discontinuous in the present context refers to a change that the human eye perceives as discontinuous, for example as a kink. It goes without saying that, viewed microscopically, discontinuous transitions also usually have a curve-like, continuous course.
- transition area is then defined in particular as the area in which the two edges of the emission surface come into contact and a change in direction reaching to this contact point compared to a direction present in the remaining area of the edges of the emission surface, for example a course that can otherwise be clearly parameterized, such as an elliptical, circular or rectilinear course, the parameters of which are then varied to the contact point, definable direction.
- the maximum diameter and the minimum diameter of the radiating surface edge of the first, ie the compact radiating sub-body are in a ratio of less than 2:1 to one another.
- the basic inventive idea can be implemented in a correspondingly meaningful manner.
- the maximum diameter and the minimum diameter of the radiating surface edge of the second, i.e. the narrow and long, radiating sub-body can be in a cumulative or alternative manner in a ratio greater than 8:1, in particular greater than 10:1, with one another thin or too narrow and long emitter body or too thin or too narrow and long emitting surface of the same is then technically no longer feasible or can no longer develop sufficient luminosity.
- the relevant limits can be experienced by a person skilled in the art simply by trying them out.
- the minimum diameter of the emission surface edge of the second, i.e. the narrow and long, partial emission body and the minimum diameter of the edge of the emission surface of the first, i.e. the compact emission part body can be in a ratio of less than 1:3 to one another.
- the narrow and long partial radiating body also has a correspondingly narrower radiating surface.
- the ratio between the minimum diameter of the radiating surface edge of the second, i.e. the narrow and long, radiating sub-body and the minimum diameter of the radiating surface edge of the first, i.e. the compact radiating sub-body is less than 1:3.5, these ratios can be maintained. This applies in particular when this ratio is even less than 1:3.2.
- the radiating surface edge of the first ie the compact radiating sub-body, is curved over at least 80%, preferably over at least 90%, of its extent, preferably circular.
- the first partial emitting body and its emitting surface can be given a compact appearance.
- the radiating surface edge of the second, i.e. the narrow and long, radiating sub-body can be designed in a straight line over at least 80%, preferably over at least 85%, of its extent, which can accordingly ensure its narrow and long appearance in a structurally simple manner.
- Different functionalities or identical functionalities can also be assigned to the two partial radiating bodies. For example, it is possible to make different configurations and combinations of indicators and taillights, for example, so that the first partial emitter can perform indicators or taillights or other functions, while the second emitter can then be used, for example, for position lights, brake lights or also indicators. Depending on the design and combination, this can increase attention even further.
- vehicle light can be understood to mean all types of humidity used on a vehicle.
- a vehicle light can be a turn signal light, a brake light, a daytime running light, a reversing light, a position light or a be rear fog light.
- the vehicle light can also be a rear light or a reversing light.
- the Road Traffic Licensing Regulations specify numerous requirements for the vehicle light, which are decisive for the roadworthiness of the vehicle.
- maximum and minimum luminosity of the vehicle light are specified, within which the luminosity of the vehicle light must move.
- light ranges can also be specified, which define which area a vehicle light must light up, so that the light can be seen directly from this area.
- further specifications from the Road Traffic Licensing Regulations can be imposed on the vehicle light permitted for road traffic.
- the light source is preferably designed as a flashing light with a frequency and a relative brightness time
- flashing light is advantageously understood to mean a direction indicator which is a lighting device on vehicles and is used to inform road users on the road about a change in direction of travel or to announce this. This can also be referred to as a "turn signal” and is part of the vehicle lighting.
- the turn signal flashes in phase with a specific frequency and clocks in such a way that the flashing light has a specific relative brightness time. Both the relative brightness time and the frequency of the flashing light are required by law for road traffic approval, so they must remain within the legally prescribed limits. Maximum and minimum values are stipulated by law in each case.
- At least one of the two emitter bodies preferably both emitter bodies, has an aerodynamic cross-section in the direction of emission or on its emission surface, which combines with the aerodynamic cross-section of the housing to form a common aerodynamic cross-section, resulting in a particularly good Cooling of the vehicle lamp can be achieved.
- the vehicle lamp is not designed to radiate but only to illuminate.
- the vehicle light can be used as a light and not as a spotlight.
- the two radiation directions of the two partial radiation bodies can also diverge from one another by less than 10°.
- the luminous area of the vehicle lamp does not scatter too much and the luminosity is approximately in the same direction from the two partial emitting bodies radiated, so that the two radiating parts can be perceived from different angles in somewhat the same luminosity.
- the vehicle lamp is preferably used as a lamp in a vehicle. If the vehicle lamp is to be used as a radiator, the beams that illuminate a bright field in a specific manner in a targeted manner cover the shape of the housing and the two emitting parts due to their dazzling effect in such a way that the intended advantages can no longer come into their own.
- the optical, electrical and thermal requirements for radiators are also so different that there are other specifications with regard to the tasks and advantages at hand.
- FIG. 1 shows a perspective view of a vehicle light
- FIG. 2 shows the vehicle light according to FIG. 1 in a front view.
- a vehicle lamp 10 comprises a housing 20, a holder 30, a first partial emitter body 40 and a second partial emitter body 50.
- the vehicle lamp 10 can also be assigned a height 31, a length 32 perpendicular to the height 31 and a depth 33 perpendicular to the height 31 and perpendicular to the length 32.
- the first partial emission body 40 has a first emission direction 41, an emission surface edge 42 and an aerodynamic cross section 49 on its emission surface surrounded by the emission surface edge 42.
- the second partial emission body 50 also has a second emission direction 51 , an emission surface edge 52 and an aerodynamic cross section 59 on its emission surface surrounded by the emission surface edge 42 .
- the partial emitting bodies 40, 50 are assembled in one piece to form a common emitting body, so that the two partial emitting bodies 40, 50 are minimally spaced apart from one another in this exemplary embodiment.
- a seam between the two partial radiating bodies 40, 50, a multiple piece configuration or an actual distance can be provided if necessary.
- the first and second partial emitting bodies 40, 50 are each aligned in a first direction of emission 41 and in a second direction of emission 51.
- the emission directions 41, 51 are the result of lighting means which are known per se and are not shown separately here, which are arranged inside the housing 20 and, depending on their function, radiate through one or the emission bodies 40, 50.
- the emission directions 40, 50 are defined as the direction in which the light from a light source or the light from a plurality of light sources representing the same functionality leaves the respective partial emission body 40, 50 with its main intensity.
- the two emission directions diverge
- the first partial emission body 40 is of compact design perpendicular to the first emission direction 41 .
- the second partial emission body 50 is narrow and long along the length 32 perpendicular to the second emission direction 51 .
- Both radiating surface edges 42, 52 of the radiating bodies 40, 50 can each be assigned a minimum diameter and a maximum diameter.
- the radiating surface edge 42 of the first compact radiating part body 40 is almost circular. The exception to this is a common emission surface edge with the second emission part body 50 at the point at which the two emission part bodies 40, 50 into one another pass over
- the radiating surface edge 42 of the first compact radiating part body 40 is to be regarded as rectilinear.
- the minimum diameter of the radiating surface edge 42 of the first compact radiating part body 40 is almost imperceptibly smaller than its maximum diameter, which corresponds to the circle diameter. Accordingly, it applies in particular that the maximum diameter and the minimum diameter of the emission surface edge 42 of the first partial emission body 40 are in a ratio of less than 2:1 to one another.
- the radiating surface edge 52 of the second narrow and long radiating part body 50 is rectangular. This also applies to the common radiating surface edge with the first radiating part body 40 at the point at which the two radiating part bodies 40, 50 merge into one another.
- the maximum diameter of the radiating surface edge 52 of the second narrow and long radiating part body 50 is significantly larger than its minimum diameter, so that the second radiating part body 50 and its radiating surface surrounded by its radiating surface edge 52 appear narrow and long.
- the maximum diameter and the minimum diameter of the emission surface edge 52 of the second partial emission body 50 are in a ratio of greater than 8:1 to one another.
- the minimum diameter of the emission surface edge 42 of the second emission part body 50 and the minimum diameter of the emission surface edge 42 of the first emission part body 40 are in a ratio of less than 1:3 to one another. This ensures that the second partial emitting body 50 and its emitting surface edge 42 is substantially narrower than the first emitting partial body 40 and its emitting surface edge 42 .
- the radiating surface edge 42 of the first radiating part body 40 is curved over 90% of its extent and is circular in shape.
- the radiating surface edge 52 of the second radiating part body 50 is formed in a straight line over at least 90% of its extent.
- the two radiating surface edges 42, 52 merge into one another in a transition region 61 with a change in direction.
- the radiating surface edge 42 of the first radiating part body 50 is round so that in the area where it meets the radiating surface edge 52 of the second radiating part body 50, its direction of curvature is first reversed radially outwards and then into the straight part of the radiating surface edge 52 of the second To open radiating part body 50 - and vice versa. This also ensures appropriate attention.
- this change in direction is so sharp that it can be described as discontinuous or appears as a kink.
- a matching radiating surface edge 62 of the two radiating surface edges 42 and 52 can be defined, which lies between the transitions of the two radiating surface edges 41, 51 as a substantially straight line.
- the vehicle light 10 is attached or attachable to a vehicle frame 11 by means of a holding arm 22 of the holder 30 .
- the holding arm 22 merges steadily into the housing 20, which, however, does not necessarily have to be the case in different embodiments.
- a front side 37 and a rear side 38 can be assigned to the housing 20, for example, starting from the emission directions 41, 51.
- the front side 37 points in the emission direction 41, 51 and the rear side 38 in the opposite direction to the emission direction 41, 51.
- the depth 33 of the emission directions 41, 51 can also be defined with a component that lies parallel to at least one of the emission directions 41, 51. If necessary, the mean value of the two emission directions 41, 51 can also be used for the definition, in particular if a definition is to be selected in which the depth 33 is to be parallel to the emission direction 41, 51 and both emission directions 41, 51 are recognizable or measurable in can be found at an angle 34 deviating from 0°.
- the length 32 can then be defined parallel to this orientation and perpendicular to the depth 33, whereupon the height 31 can then be defined perpendicular to the length 32 and perpendicular to the the depth 33 follows.
- the height 31 also has a maximum height of 35.
- the common housing 20 is designed in the form of a wing or an aerofoil.
- the housing 20 has a greater depth 33 than height along at least 90% of the length of the common housing 20, at least starting from one or the maximum height 35 of the common housing 20 in a direction 36 pointing away from the mount 30 31 on.

- the front and rear sides 37, 38 of the housing 20 each have a rectilinear area 23 which, starting from the holder 30, approaches one another along the length 32. As can be seen, in this exemplary embodiment, these rectilinear areas 23 start only after the maximum height 35 or only after the first partial emitter body 40.
- the housing overhang 21 is the cross section perpendicular to the length 32 smaller than the height 31 of the associated emitter body 40, 50 in this cross section. As can be seen in particular from FIG.
- the housing projection 21 also tapers in a tapering region 24 along the length 32 pointing away from the holder 30 or from the holder-side end of the second partial emitting body 50 .
- the housing overhang 21 in the transition area 61 is larger than on both sides of the transition area 61.
