Description

The invention relates to a vehicle light according to the preamble of claim 1 and a method according to the preamble of claim 11.

A vehicle lamp comprises, for example, a lamp interior that is essentially enclosed by a lamp housing and a lens and at least one illuminant accommodated therein, comprising at least one light source, for at least one light function of the vehicle lamp.

The lens is nowadays usually made of a plastic, transparent cover which closes the interior of the luminaire and protects the components housed therein, such as one or more lamps, reflectors and alternatively or additionally provided optical elements against the effects of the weather.

The luminaire housing or the luminaire interior can be divided into several chambers each with its own light sources and / or lighting means and / or optical elements and optionally light discs, of which several chambers can fulfill the same and / or each chamber can fulfill a different lighting function.

Each vehicle light, in particular an automobile light, fulfills one or more tasks or functions, depending on the configuration. A light function of the vehicle light is provided to fulfill each task or function.

A distinction must be made between lighting functions that serve a temporary and, accordingly, individual, additional purpose that differs from vehicle to vehicle, such as interior lighting or exit lighting, and those that enable a vehicle, in particular a motor vehicle, to participate in road traffic through a statutory Rules are required.

Individual, because they are neither required by law with regard to their arrangement on or in the vehicle, light color and luminosity nor implemented in every vehicle, at least from vehicle model to vehicle model different, for example desired or undesired, or even personalizable additional light functions are, for example, the already mentioned interior lighting or Exit lighting, but also so-called “welcome home” or “greeting” light functions and / or light function sequences. A light display of a type of propulsion currently used and / or exercised by a vehicle with, for example, a multivalent drive concept when participating in road traffic represents - at least for the moment - an individual light function.

For the participation of a vehicle in road traffic, which are presupposed by the legislator through a set of rules for the participation of a vehicle, in particular a motor vehicle in road traffic, which can also be referred to as traffic, legal standard or normal light functions, for example, when configured as a headlight are a The function illuminating the road, or in the case of a configuration as a signal light, a signal function, such as a repeat flashing light function for indicating the direction of travel or a brake light function for indicating braking activity, or a position light function, such as a rear light function, to ensure visibility of the vehicle during the day and / or night, such as in the case of a configuration as a rear light or daytime running light.

Each standard light function must fulfill a legally prescribed light distribution, for example. The light distribution defines at least to be complied with, colloquially referred to as brightness in light fluxes in at least to be complied with solid angle areas.

In some cases, different brightnesses or visibility ranges and in some cases different light colors are assigned to the individual prescribed standard light functions.

Examples of vehicle lights that fulfill standard light functions are repeater lights, exit lights, e.g. for ambient lighting, marker lights, brake lights, fog lights, reversing lights, and typically high-set third brake lights, so-called central, located on the front of the vehicle, on the vehicle flanks and / or on the side mirrors and on the rear of the vehicle , High-mounted braking lights, daytime running lights, headlights and fog lights used as turning or cornering lights, as well as combinations thereof.

Such a combination is, for example, regularly implemented in the known rear lights. In these, for example, repeat indicators, marker lights, brake lights, fog lights and reversing lights are used, to name just one of the many combinations implemented in rear lights. This list does not claim to be exhaustive, nor does it mean that all the lights mentioned have to be combined in a rear light. For example, only two or three of the mentioned or other lights can be combined with one another in a common light housing of a rear light.

In order to comply with a predetermined light distribution of a control light function, one or more optical elements for guiding light that contribute to the shaping of a light distribution can be assigned to at least one light source of the illuminant of a vehicle lamp.

The optical elements mentioned can be at least one reflector and / or at least one lens and / or one or more optical disks or the like arranged in the beam path between at least one light source of the illuminant and the light disk.

For example, at least one reflector arranged behind at least one light source of at least one illuminant can be accommodated in the luminaire interior. The reflector can be formed at least in part by a separate component and / or by at least a part of the lamp housing itself, for example by means of an at least partial reflective coating.

The lens itself can alternatively or additionally be designed as an optical element, for example by being provided, preferably on the inside thereof, with an optical structure that contributes to the generation of one or more previously mentioned light distributions. This means that an optical disk can be dispensed with, if necessary.

Due to the light distributions, light colors and the corresponding required configuration of the lighting means that contribute to their fulfillment, the implementation of control light functions of vehicle lights, in particular automobile lights, is typically very complex and costly. Accordingly, special components such as Optics, reflectors, circuit boards, cooling plates, connections, etc. are required. It is therefore very difficult to implement a standard light function in a flexible manner.

Since the trend in the automotive industry is towards a constantly growing variety of models, a certain flexibility in the luminaire design, especially in the design with both control light functions and additional light functions when using a common basic light, would be very helpful and cost-saving.

Currently, in the course of environmental discussions - such as about fine dust - there is also increasing emphasis on identifying the different drive systems such as Diesel, gasoline, hydrogen, gas, electric, etc. spoken.

Apart from that, users of electric vehicles, for example, want to express their environmental awareness to the outside world, in the sense of "I'm doing something for the environment!"

Due to their high degree of efficiency in converting electrical current into light that is visible to the human eye, inorganic light-emitting diodes are increasingly being used as light sources for lamps, especially vehicle lights, and organic light-emitting diodes are already being used in a few vehicle models.

Inorganic light-emitting diodes consist of at least one light-emitting diode semiconductor chip, or LED chip for short, as well as at least one primary lens that is molded on, for example by injection molding, and which completely or partially envelops the at least one LED chip. Vehicle lights are also known in which pure LED chips are used without integrally molded primary optics.

In the following, therefore, for the sake of simplicity, a distinction is no longer made between inorganic light-emitting diodes and LED chips, and instead the term LED is used uniformly to represent both, unless something else is explicitly mentioned.

An organic light-emitting diode, referred to for short as OLED (Organic Light Emitting Diode; OLED), is a luminous thin-film component made of organic semiconducting materials with at least one emitter layer enclosed between electrically conductive, for example metallic layers for the anode and cathode. The thickness or, in other words, the thickness of the layers is in the order of magnitude of about 100 nm. Depending on the structure, it is typically 100 nm to 500 nm.

The layers of an OLED are applied one after the other to a substrate which, together with an encapsulation applied to the top layer, protects the layers of the OLED against water, oxygen and other environmental influences such as scratch damage and / or pressure.

In contrast to inorganic light-emitting diodes, OLEDs do not require any single-crystal materials. In comparison to LEDs, OLEDs can therefore be manufactured using cost-effective thin-film technology. OLEDs thus enable the production of flat light sources which are on the one hand very thin and on the other hand as a luminous surface that is visible through the lens of a vehicle lamp and that shines homogeneously when switched on used have a particularly homogeneous appearance. In addition, OLEDs have a similarly high level of efficiency in converting electrical current into light visible to the human eye as LEDs.

Disadvantages of OLEDs are their reduced temperature resistance compared to LEDs and their reduced resistance to environmental influences, in particular moisture and atmospheric oxygen. Both of these lead to a limited service life of OLEDs.

An alternative to obtaining luminous surfaces that appear homogeneous uses the physical effect of photoluminescence. This provides for the use of a flat element which is provided with fluorescent particles, the fluorescence of which is excited by one or more excitation light sources emitting, for example, light in the ultraviolet part of the electromagnetic spectrum outside the range visible to the human eye. Ultraviolet electromagnetic radiation, however, has a harmful effect on all forms of organisms, in particular microorganisms and, inter alia, on the human eye. An additional disadvantage arises in connection with plastics, from which nowadays, with the exception of a few electronic components housed in the interior of the luminaire, including the light sources, in addition to the luminaire housings and light panes at least partially surrounding the interior of the luminaire, predominantly all the components of vehicle lights that delimit the interior of the luminaire and / or are housed there. These components made of plastic and cannot be protected from the effects of ultraviolet electromagnetic radiation, including lens and lamp housing, are subject to accelerated aging, which is caused by embrittlement and reduced impact resistance of all components, as well as clouding and reduced optical quality, at least within the for Electromagnetic radiation visible to the human eye from transparent components.

In order to create a vehicle light with a light source which, when switched on, has a homogeneously luminous luminous surface with a high light density that is suitable for fulfilling a light function of a light, in particular a vehicle light, or at least contributes to a prescribed light distribution of a light function of a vehicle light and, moreover, can be produced cost-effectively, has a long service life and does not pose a health risk EP 3 355 664 A1 known that the illuminant comprises an excitation light source and a fluorescent element, which by means of at least one light color, briefly referred to as the excitation light color, of the light emitted by the excitation light source within the briefly referred to as the visible range of the electromagnetic spectrum, which is visible to the human eye, to be emitted from within The light lying in the visible area, referred to as emission color for short, can be excited and has at least one luminous surface which illuminates during an excitation to emit light, through which the light emitted by the fluorescent element during an excitation to emit light at least partially exits. The excitation light color is blue, for example, and the emission color is red, for example.

Furthermore is through DE 10 2011 015 012 A1 a vehicle lamp known which is equipped with a light source whose light emission provides a light function for the vehicle. The vehicle lamp comprises a housing with a light exit opening in which a lens, also referred to as a light cover lens, is arranged. The light emission of the light source emerges through the light exit opening. A light module into which light is coupled via a light coupling surface is arranged inside the housing. The light module comprises a luminescent material that is excited by the coupled light. Light which was generated by the luminescent material emerges via a light decoupling surface of the light module that is at least partially surrounded by an opaque surface area.

One object of the invention is to create a compact vehicle light for fulfilling one or more control light functions and with at least one easily customizable additional light function, as well as to specify a method for operating such a vehicle light.

The object is achieved with the features of the independent claims.

Advantageous embodiments are reproduced in the claims, the drawings and in the following description, including that associated with the drawings.

A first subject matter of the invention accordingly relates to a vehicle lamp with a lamp interior, which is essentially enclosed by a lamp housing and a lens, and has at least one lamp chamber.

The interior of the luminaire is then divided into one or more luminaire chambers.

The luminaire interior houses at least one standard lamp with at least one Standard light source for at least one standard light function, preferably red light color of the vehicle lamp.

The standard light source emits light in a standard light color prescribed for the standard light function.

The standard light source with its one or more standard light sources serves to fulfill at least one standard light function, preferably red light color of the vehicle light.

At least one standard light source of the standard illuminant is housed in a lamp chamber which is covered by a part of the lens that is transparent at least in the region of the electromagnetic radiation that is visible to the human eye.

The lens section is colored in one of the standard light color of the standard light function to be fulfilled by the standard light source - preferably red.

The light disk section has, for example, a colorless transmission area that is free from the coloring.

In addition, an additional light source of an additional light source, which is also housed in the interior of the luminaire, is arranged in the lamp chamber covered by the lens section. The additional light source emits light in an additional light color different from the light color of the standard light function.

The additional light color is preferably different from the standard light color in such a way that it is completely absorbed by the coloring of the part of the lens. In other words, it is impossible for the additional light color to pass through the colored part of the lens section.

In this way, light in the normal light color passes both through the colored part and through the, for example, colorless transmission area of the light pane part.

Light in the additional light color, on the other hand, cannot pass through the colored part of the lens section. The part of the lens can only pass through the, for example, colorless transmission area.

In addition, the lens part can have a fluorescence area with a fluorescent element, also referred to as a fluorescence element.

The fluorescent element can be excited at least by the additional light color of the light emitted by the additional light source within the part of the electromagnetic spectrum which is briefly referred to as the visible range and visible to the human eye to emit fluorescent light which is also within the visible range.

The fluorescent element forms at least one area, which is briefly referred to as a fluorescent luminous area, and which illuminates during an excitation to emit fluorescent light in a fluorescent light color within the light disk section.

The fluorescent light emitted by the fluorescent element emerges at least partially through the at least one fluorescent luminous surface.

When looking from outside the lamp chamber through the lens section, the fluorescence area coincides with the fluorescence luminous surface.

In other words, the fluorescence area comprises the fluorescence luminous area.

The fluorescence light color of the fluorescence light is different from the additional light color.

Thus, when the additional light source is active, light in the additional light color shines through the, for example, colorless transmission area and, moreover, the fluorescent light surface in the lens section lights up in the fluorescent light color when the additional light source is active.

A particularly advantageous embodiment of the invention provides that the fluorescence area with the fluorescence luminous area is surrounded by the, for example, colorless transmission area.

The fluorescence area with its fluorescence luminous area is therefore within the, for example, colorless transmission area.

The fluorescence light color is preferably in the same wavelength range as the standard light color. For example, the fluorescence light color is included in the wavelength range of the standard light color.

The fluorescent element is advantageously excited to emit red light. The fluorescent element therefore preferably emits red light.

The excitation for emitting fluorescent light is advantageously carried out by means of blue light.

The additional light color blue is particularly preferred.

A particularly preferred embodiment of the vehicle lamp provides an additional light source that emits only blue additional light color and a fluorescent element that can be excited by blue light to emit red fluorescent light.

In addition to the light emitted by it to excite the fluorescent element to emit fluorescent light in at least one first additional light color, the additional light source can emit additional light in at least a remaining part of the visible area.

The light disk section can be a separate light disk of the respective lamp chamber, or it can be a section of a light disk that covers the respective lamp chamber and covers further parts of the lamp interior.

• - zumindest eine zweite Partie mit dem fluoreszierenden Element umfasst, welches durch wenigstens eine Zusatz-Lichtfarbe des von der Zusatz-Lichtquelle innerhalb des sichtbaren Bereichs abgestrahlten Zusatz-Lichts zur Abgabe von ebenfalls innerhalb des sichtbaren Bereichs liegendem Fluoreszenz-Licht anregbar ist, und welche mindestens eine während einer Anregung zur Abgabe von Fluoreszenz-Licht leuchtende Fluoreszenz-Leuchtfläche aufweist, durch welche das vom fluoreszierenden Element während einer Anregung zur Abgabe von Fluoreszenz-Licht abgegebene Fluoreszenz-Licht zumindest teilweise austritt, und
• - zumindest eine an die zweite Partie angrenzende dritte Partie umfasst, durch welche das von der Zusatz-Lichtquelle innerhalb des sichtbaren Bereichs abgestrahlte Zusatz-Licht zumindest teilweise austritt.

It is important to emphasize that the invention can be implemented by a vehicle lamp with a lamp interior which is at least partially enclosed by a lamp housing and a lens that is transparent at least for light in the visible range, in which an additional light source is at least partly housed and which has a through Visible, in particular blue light for the emission of red light carries excitable fluorescent element in its lens, the lens:

• - At least a first section with a color filter, which at least the additional light emitted by the additional light source in the additional light color provided for exciting the fluorescent element to emit fluorescent light at a passage through the lens to the outside of the luminaire interior prevents
• - At least one second part with the fluorescent element, which can be excited by at least one additional light color of the additional light emitted by the additional light source within the visible range to emit fluorescent light also within the visible range, and which at least has a fluorescent luminous surface which is luminous during excitation to emit fluorescent light and through which the fluorescent light emitted by the fluorescent element during excitation to emit fluorescent light at least partially exits, and
• - At least one third part adjoining the second part, through which the additional light emitted by the additional light source within the visible range exits at least partially.

The third part can surround the second part and / or advantageously be arranged between the first and second part.

• - Aktivierung der Zusatz-Lichtfunktionen bei Vorliegen der Betriebsbedingungen als Ergebnis der Analyse.

A second subject matter of the invention relates to a method for operating an additional light function in a vehicle equipped with a vehicle lamp with an additional light function. The procedure comprises the following steps:

• - Determination of parameters depending on which the additional light function should be operated,
• - Analysis of the parameters as to whether or not there are operating conditions for the additional light function, and
• - Activation of the additional light functions when the operating conditions are present as a result of the analysis.

In addition, if the operating conditions do not exist, the additional light functions can be deactivated as a result of the analysis.

The parameters, depending on which the additional light function is to be operated, can include an instantaneous drive mode associated with an instantaneous pollutant emission of the vehicle equipped with the vehicle lamp with an additional light function.

For example, it is conceivable that the additional light function is activated as soon as the vehicle equipped with the vehicle light with the additional light function is in a driving state that is particularly poor or even free of carbon dioxide and / or nitrogen oxide and / or fine dust emissions.

As an alternative or in addition, the parameters on which the additional light function is to be operated can include an activity of the owner of the vehicle equipped with the vehicle lamp with an additional light function. Examples of corresponding activities are approaching the holder to the vehicle or moving the holder away from the vehicle, opening or closing at least one vehicle door of the vehicle, remote unlocking or remote locking of at least one vehicle door of the vehicle. Without claiming to be exhaustive, these are just a few conceivable examples of the owner's activities.

The holder can carry out his activities, for example, by means of a radio remote control whose location and / or signals can then serve as a basis for determining parameters.

The invention generally enables the creation of special light functions, particularly conspicuous at close range, which, due to their low level of radiation of, for example, blue light through the lens, which is overshadowed by the red light mainly emitted by a rear light, could even be operated while driving under the current legal situation.

In the light of the spread of alternative travel drives to the internal combustion engine, this can be a special feature for alternatively driven vehicles.

This can also represent a unique selling point for vehicle lights in conventionally powered vehicles.

The invention creates a novel light function for a flexible appearance of vehicle lights.

As an alternative or in addition, the vehicle light can have individual features or a combination of several features described in the introduction in connection with the prior art and / or in one or more of the documents mentioned in relation to the prior art and / or in the following description of the exemplary embodiments shown in the drawings .

Additional advantages over the prior art that go beyond the complete solution of the task set and / or beyond the advantages mentioned above for the individual features are a high degree of flexibility and cost savings in the luminaire design.

In addition, the invention allows for example in vehicles with bi-, tri- or multivalent drive options to carry a currently predominant drive type to the outside and thereby make it visible.

This can be of particular interest in the context of environmental zones, for example.

In addition, the invention allows special lighting effects to be designed for lighting functions of vehicle lights. This is becoming more and more important for the end customer, which can be seen, for example, in the increasing willingness to incur significant additional prices for only a small amount of added value in terms of vehicle technology or an optical gain.

One in 1 , 2 , 3 Vehicle light shown in whole or in part 01 includes:

• - A light disk that is essentially transparent to a lamp housing and at least to light in the region of the electromagnetic wavelength spectrum that is visible to the human eye 02 at least partially enclosed luminaire interior 03 with at least one light chamber 30th ,
• - At least one at least partially in the interior of the luminaire 03 housed rule Luminous means with at least one part of the light disk that is transparent from at least one area of the electromagnetic radiation that is visible to the human eye 20th covered lighting chamber 30th arranged control light source emitting light in a control light color for at least one control light function, preferably red light color of the vehicle lamp 01 , and
• - At least one at least partially in the interior of the luminaire 03 Housed additional light source with at least one in the part of the transparent lens 20th covered lighting chamber 30th arranged additional light source emitting light in an additional light color different from the standard light color of the standard light function for at least one additional light function, preferably blue light color of the vehicle lamp 01 .

The transparent lens section 20th has a color filter area 21st on that with a color filter 22nd is provided which allows the standard light color to pass, for example by being colored in one of the standard light color of the standard light function to be fulfilled by the standard light source - preferably red - and light in one of the standard light color different light colors at one passage through the lens 02 prevents

The transparent lens section 20th has, for example, a colorless transmission range 23 on that free from the color filter 22nd , for example is free from the coloring.

The luminaire interior 03 can be placed in one or more light chambers 30th be divided.

The one or more control light sources emit light in a preferably red control light color prescribed for the control light function.

The standard lighting means for at least one standard lighting function of the vehicle lamp 01 serves with its one or more lights in a regular light color emitting control light sources accordingly to fulfill a control light function of the vehicle lamp 01 or fulfills a standard light function of the vehicle light 01 at least at. The latter is the case, for example, when the standard light emitted by the standard light sources of the standard light source only provides part of a light distribution prescribed for the standard light function and the remaining part of the light distribution prescribed for the standard light function from other, for example in other luminaire chambers in the same luminaire interior 03 the same vehicle light 01 or in a lamp chamber and / or a lamp interior of another vehicle lamp accommodated standard light sources of one or more other standard lighting means is obtained.

The additional light source emits light in a preferably blue additional light color that differs from the light color of the control light function.

The additional light color is preferably so different from the standard light color that the color filter generated, for example, by the coloring 22nd the lens section 20th it completely absorbed. In other words, it is impossible for the additional light color, for example due to the colored part of the lens section 20th formed color filter area 21st the lens section 20th to get through.

In this way, light in the normal light color both passes through the color filter area formed, for example, by a colored part 21st , as well as through the transmission area formed, for example, by a colorless part 23 the lens section 20th through.

Light in the additional light color, on the other hand, cannot pass through the color filter area formed by a colored part, for example 21st the lens section 20th get through. It can be the part of the lens 20th only through the transmission area formed, for example, by a colorless part 23 pass through.

1 shows a cross section through the lens 02 an appropriately designed, flexibly designed vehicle light 01 . Due to its simplest implementation, it represents a basic version, also known as a basic luminaire, free of the configurations and additional features described below.

The vehicle light 01 in their basic version according to the in 1 illustrated embodiment is characterized in that the interior of the luminaire 03 is evenly illuminated in blue, but this blue light only in the transmission range 23 at the specifically intended and freely changeable recesses of the red cycle in the lens 02 can decouple. The one when looking from outside the interior of the luminaire 02 through the lens 02 transmission area designed through it, for example in the form of a graphic 23 this lights up blue. This allows a blue glowing graphic inside the light disc 02 be achieved.

An advantageous development of the vehicle light 01 provides that the light pane part has a fluorescence area 24 with one too as a fluorescent element 25th designated fluorescent element.

The fluorescent element 25th is at least for example by the light emitted by the additional light source within the briefly referred to as the visible range of the electromagnetic spectrum in the additional light color that is visible to the human eye to emit fluorescent light in a different color from the additional light color Fluorescence light color within the visible range can be excited.

The fluorescent element 25th forms at least one short fluorescent light surface 26th designated, luminous area within the lens section 20th that during a stimulation to emit fluorescent light when looking from outside the lamp chamber 03 on the lens section 20th lights up in the fluorescent light color.

The one from the fluorescent element 25th emitted fluorescent light passes at least partially through the at least one fluorescent light area 24 out.

When looking from outside the light chamber 03 through the lens section 20th the fluorescence range is right through it 24 with the fluorescent light surface 26th match.

In other words, the fluorescence range includes 24 the fluorescent light area 26th .

The fluorescence light color of the fluorescence light is different from the additional light color.

Thus, when the additional light source is active, light in the additional light color shines through the, for example, colorless transmission area 23 and in addition, the fluorescent light area lights up 26th in the lens section 20th with an active additional light source in the fluorescent light color.

2 shows a cross section through the lens 02 a flexibly designed vehicle light designed according to the development 01 .

In the 2 vehicle light shown 01 is a further development in that its appearance compared to the in 1 The embodiment shown is expanded in the fluorescent materials to the lens 02 are bound, which one or more for example on or in the lens 02 arranged fluorescent elements 25th form. In this way, a light function is achieved which, when excited, for example with light emitting blue from an excitation light source in the vehicle lamp 01 , for example an additional light source, through the combination of fluorescence areas 24 and recesses in the color filter area formed, for example, by a red cycle 21st the lens 02 , red and blue glowing elements.

An additional development of the vehicle light described above 01 is in 3 shown. At the in 3 vehicle light shown 01 is the fluorescence range 24 with the fluorescent light surface 26th from, for example, the colorless transmission range 23 at least partially surrounded.

The fluorescence area 24 lies with its fluorescent light surface 26th at least immediately adjacent to the, for example, colorless transmission area 23 or within the, for example, colorless transmission range 23 .

This embodiment of the invention can be achieved by a vehicle light 01 be realized with one of a lamp housing and a lens that is transparent at least for light in the visible range 02 at least partially enclosed luminaire interior 03 , in which a standard light source and an additional light source are at least partially accommodated, and which have a fluorescent element that can be excited by visible, in particular blue light to emit red light 25th in their light disk 02 carries, with the lens 02 :

• - at least one as a color filter area 21st marked first part with a color filter 22nd comprises, which allows at least the standard light emitted by the standard light source in a standard light color to pass and at least that of the additional light source in the one for exciting the fluorescent element 25th Additional light color provided for emitting fluorescent light, additional light emitted at a passage through the lens 02 through to the outside of the luminaire interior 03 prevents
• - at least one as a fluorescence area 24 labeled second part with the fluorescent element 25th comprises, which can be excited by at least one additional light color of the additional light emitted by the additional light source within the visible range to emit fluorescent light in a fluorescent light color also lying within the visible range, and which at least one during an excitation for the emission of fluorescent light in the fluorescent color luminous fluorescent light surface 26th has through which the fluorescent element 25th during a suggestion for Emission of fluorescent light emitted fluorescent light at least partially exits, and
• - At least one adjacent to the second part, as a transmission area 23 designated third part, through which both the standard light emitted by the standard light source in the standard light color lying within the visible range, as well as the additional light emitted by the additional light source in the additional light color lying within the visible range Light emerges at least partially.

The third part can surround the second part and / or advantageously be arranged between the first and second part.

At the in 3 vehicle light shown 01 their appearance compared to the in 2 The luminaire shown can therefore be expanded further in that the color filter area or areas formed, for example, by a red cycle in an injection molding manufacturing process 21st the lens 02 penetrating fluorescent elements 25th with a transmission area formed for example by a clear tact in an injection molding manufacturing process 23 are framed so that the fluorescent element 25th when the additional light source is activated, it is framed by a frame that shines in blue, for example.

This could be, for example, when displaying an electric drive variant with a corresponding vehicle light 01 equipped vehicle find use.

It is important to emphasize at this point that according to the representations in 1 , 2 , 3 a clear act basically an outside of the lens 02 can form, whereas a red cycle can form the color filter area 21st and a recess of the red cycle and a recess of an optionally provided fluorescence area 24 the transmission area 23 can form.

In 1 , 2 , 3 is the clear tact or the so-called skin mold of the lens 02 shown hatched. For example, by coloring with the color filter 22nd The injection molding cycle provided and therefore briefly referred to as the color cycle is shown in black. The transmission area is located where the clear clock is free from the color clock 23 . The color filter area is located where the clear tact is covered by the color bar 21st . The fluorescent element 25th is shown in white. The fluorescent element 25th penetrates the color rhythm. The fluorescent element 25th can be covered by the clear tact on the outside. In principle, the fluorescent element 25th also on the outside flush with the Klartakt or even protrude beyond the Klartakt.

According to one possible embodiment of the vehicle light 01 with fluorescent element 25th the fluorescence light color is included in the wavelength range of the standard light color.

The fluorescence light color is preferably in the same wavelength range as the standard light color.

The fluorescent element is preferably excited to emit red light.

The fluorescent element therefore preferably emits red light.

It is conceivable that the excitation for the emission of fluorescent light takes place by means of blue light.

2 and 3 each show a vehicle light 01 which is a fluorescent element that can be excited by visible, in particular blue light to emit red light 25th in their light disk 02 wearing. The additional light source, which preferably emits blue light and is also referred to as an excitation light source, is in a lamp chamber 30th houses, which houses a provided for fulfilling a red light function, briefly referred to as a standard light source, another light source.

The fluorescent element 25th can of one as a transmission area 23 designated, for example colorless, for example clear part of the otherwise for example red lens 02 be surrounded or adjacent.

Alternatively or additionally, the otherwise red lens 02 one or more transmission areas formed by, for example, colorless areas 23 have, through which the light of the excitation light source from the interior of the luminaire 03 out through the lens 02 passes through.

A particularly preferred embodiment of the vehicle light 01 sees an additional light source emitting only blue light and a fluorescent element that can be excited by blue light to emit red fluorescent light 25th in front.

The additional light source can be used in addition to that of it to excite the fluorescent element 25th to emit fluorescent light in at least one first additional light color, emit additional light in at least one second additional light color lying, for example, in a remaining part of the visible region.

In principle, it is also conceivable in this context that the additional light source is used to excite the fluorescent element 25th light emitted to emit fluorescent light in at least one first additional light color is not in the visible range, but outside it.

Accordingly, the fluorescent element 25th be stimulated by additional light in a region of the electromagnetic wavelength spectrum that is outside the range of the electromagnetic wavelength spectrum that is visible to the human eye, to emit fluorescent light in a fluorescent light color that is different from the additional light color and is within the visible range.

The additional light source emits in addition to that of it to excite the fluorescent element 25th to emit fluorescent light in the first additional light color emitted light additional light in at least one second additional light color lying in the visible range.

The additional light color is advantageously blue, or the additional light color comprises blue light.

With the lens section 20th it can be a separate light disc covering the respective lamp chamber 02 act.

Alternatively, it can be with the lens section 20th the respective light chamber 30th covering section of another part of the interior of the luminaire 03 covering lens 02 act.

The vehicle light 01 comprises, for example, a light disk that is essentially transparent to a lamp housing and a light disk that is transparent at least to light in the area visible to the human eye 02 at least partially enclosed luminaire interior 03 .

In the light interior 03 is at least one standard lighting means to fulfill at least one standard lighting function of the vehicle lamp 01 at least partially accommodated.

In the light interior 03 is also at least one additional light source with at least one additional light source to fulfill at least one additional light function of the vehicle light 01 at least partially accommodated.

The vehicle light 01 can have one or more color filters 22nd include, of which at least one, for example an external color filter 22nd executed color filter 22nd , at least that of the additional light source in the example to excite a fluorescent element 25th Additional light color provided for emitting fluorescent light, light emitted at a passage through the lens 02 through to the outside of the luminaire interior 03 prevent. That or the corresponding color filter 22nd filter the corresponding at least one additional light color before or during the passage through the lens 02 from the through the lens 02 light emerging through it.

That or the color filter 22nd can light in from them at the passage through the lens 02 to the outside of the interior of the luminaire 03 hindered at least one additional light color back into the interior of the luminaire 03 reflect completely or partially and / or absorb completely or partially.

That or the color filter 22nd let light in the by excitation of the optionally provided fluorescent element 25th emitted fluorescent light color from the interior of the luminaire 03 exit, for example happen.

Alternatively or additionally, at least one can be in the optical path between the additional light source and the optionally provided fluorescent element 25th arranged color filter may be provided, which is designed as an inner color filter, exclusively from the additional light source in the excitation of the fluorescent element 25th for emitting fluorescent light provided additional light color emitted light to the fluorescent element 25th lets happen.

In conjunction with an outer color filter, which is non-transparent for the light color for which the inner color filter is transparent, the additional light source can be completely passed through the lens before the outside 02 through into the interior of the luminaire 03 hide from looking observer.

The additional light source can advantageously be arranged in a concealed manner in a part of the interior of the luminaire that cannot be seen from outside through the lens.

For example, the additional light source can be arranged behind a diaphragm and thus one from outside through the lens 02 areas that cannot be seen through lie behind a panel.

A preferred embodiment of the particular as a vehicle lamp 01 trained lamp sees a red lens 02 before in connection with light emitted from the additional light source in blue additional light color to excite the fluorescent element 25th to emit light.

The vehicle light 01 is suitable to meet a growing need for lights whose appearance should be able to be varied, but should be based on a common basic light for reasons of cost. This can also be used to display electrical versions of individual vehicle models without the need for a completely separate light.

A configuration that is also suitable for the formation of an additional light function with a distinctive coloring is based on an illuminated interior of the luminaire filled with blue additional light 03 or at least from an illuminated lamp chamber filled with additional blue light 30th out.

In the simplest case, an otherwise red-colored lens can be used 02 in places the red color filter area 23 be left out, as shown in 1 is shown. This becomes a vehicle light 01 with a flexibly designed and variable lens 02 in which the resulting graphic lights up blue, with the basic light remaining the same. After that, by changing the lens 02 the appearance of one and the same lamp housing of a vehicle lamp 01 to be changed.

Now becomes like in 2 shown on the lens 02 a fluorescent element 25th injected, which the red lens 02 can also penetrate, the fluorescent element becomes through the blue light 25th made to glow red while the rest of the red lens 02 remains dark because the blue light does not pass through the red lens 02 x-rayed. Through the described combination of leaving out the red color filter area 23 and introducing the fluorescent element 25th into the lens 02 can use the red fluorescent element 25th with the blue glowing recesses of the red clock at the same time in the lens 02 shine.

Now that will be the lens 02 penetrating fluorescent element 25th embedded in a circumferential clear tact, as in 3 shown, gets the red glowing fluorescent element 25th another glowing blue border. An effect that could, for example, be a very clear representation of an electric variant.

The fluorescent elements 25th are in a vehicle light 01 stimulated with blue light, which however by a red light disc 02 does not penetrate. The blue coupling light is converted into red light in the fluorescent material. This emerges in concentrated form at the edge zones and is now through the red lens 02 clearly visible. An effect is achieved in that one has a fluorescent light surface 26th in the lens 02 lights up without recognizing a light source.

This fluorescence lighting technology makes sense, for example, for parts where there is no other possibility of inconspicuously coupling light in and there is no other cheaper and more efficient lighting technology than the fluorescence lighting technology described above.

The variants described here are used to create vehicle lights 01 with a flexibly designable appearance with the same luminaire base.

This can be done by changing the lenses 02 the appearance can be changed significantly without having to change the base of the luminaire.

This can be used for temporary light functions such as a Wellcome Home function as well as for permanently illuminated light functions such as a tail light function, provided the light functions remain in the legally prescribed color spectrum.

Up to now, luminaire variants have usually been implemented using their own luminaires with their own tools. However, this is only possible with large quantities and is very cost-intensive.

The vehicle lamp described above 01 is suitable for carrying out a method for operating an additional light function in one with a vehicle light 01 vehicle equipped with additional light function.

• - Ermittlung von Parametern, in Abhängigkeit von denen die Zusatz-Lichtfunktion betrieben werden soll,
• - Analyse der Parameter, ob Betriebsbedingungen für die Zusatz-Lichtfunktion vorliegen oder nicht, und
• - Aktivierung der Zusatz-Lichtfunktion bei Vorliegen der Betriebsbedingungen als Ergebnis der Analyse.

The procedure comprises the following steps:

• - Determination of parameters depending on which the additional light function should be operated,
• - Analysis of the parameters as to whether or not there are operating conditions for the additional light function, and
• - Activation of the additional light function when the operating conditions exist as the result of the analysis.

• - Deaktivierung der Zusatz-Lichtfunktionen bei Nicht-Vorliegen der Betriebsbedingungen als Ergebnis der Analyse.

An advantageous further development of the method includes the additional method step:

• - Deactivation of the additional light functions if the operating conditions do not exist as a result of the analysis.

The parameters, depending on which the additional light function is to be operated, can have a momentary drive mode associated with a momentary pollutant emission of the vehicle light 01 include a vehicle equipped with an additional light function.

For example, it is conceivable that the additional light function is activated as soon as a driving state of the vehicle light is detected 01 A vehicle equipped with an additional light function is present which is particularly poor or even free of carbon dioxide and / or nitrogen oxide and / or fine dust emissions.

As an alternative or in addition, the parameters on which the additional light function is to be operated can be an activity of a holder of the vehicle light 01 include a vehicle equipped with an additional light function. Examples of corresponding activities are approaching the holder to the vehicle or moving the holder away from the vehicle, opening or closing at least one vehicle door of the vehicle, remote unlocking or remote locking of at least one vehicle door of the vehicle. Without claiming to be exhaustive, these are just a few conceivable examples of the owner's activities.

The holder can carry out his activities, for example, by means of a radio remote control whose location and / or signals can then serve as a basis for determining parameters.

For example, the additional light function implemented as a welcome light function in a case described above, for example, can be deactivated again as soon as the vehicle light occurs 01 Vehicle equipped with an additional light function is ready to participate in the flowing traffic or it participates in it again. For this purpose, parameters can at least be included in the acquisition and analysis, which include, for example, starting an engine and / or a person taking a seat in the driver's seat, and / or, for example, pressing a pedal for the first time after opening and / or closing a vehicle door, and / or the switching on of an engine ignition and / or the activation of readiness to drive, to name a few examples without claiming to be exhaustive of the possible options.

This is particularly conceivable as an advantage in a vehicle with fuel cell and / or battery electric drive - for example in addition to an internal combustion engine - because the momentary movement associated with the use of the fuel cell and / or battery electric drive is free of pollutant emissions at least on Is the location of the vehicle. For example, in the context of environmental zones, an activation of an additional light function linked to the presence of a corresponding parameter can be used advantageously to display the pollution-free operation of the vehicle to the outside through the additional light function, for example to obtain a residence and / or drive-through permit or a to indicate toll-free driving in a special area.

The process looks to the activation of the additional light function in the fourth process step 304 following a cyclical repetition starting with the first process step 301 in front.

Is the result of the analysis in the second process step 302 that the operating conditions for the additional light function are not present, the second process step follows 302 a fifth process step 305 , which provides a query of the current activity of the additional light function.
