Description

Method for controlling light fixtures

technical field

The invention relates to a method for controlling a lamp of a motor vehicle, such as in particular a headlamp or a rear lamp.

Background technique

Luminaires of motor vehicles are used, for example, as rear lights to assume the functions of rear lights, brake lights and, where appropriate, flashing lights. As lamps for motor vehicles, headlights for the front of the motor vehicle are also known, by means of which headlights can produce daytime running lights, parking lights, dipped beams and/or high beams and, where appropriate, also There are other lamp types for the front area of motor vehicles.

In this case, these lamps are usually only used during driving operation, wherein in some vehicles the switching on and off of the lamps takes place directly with the ignition of the internal combustion engine switched on or off or, if appropriate, also after switching off the ignition An adjustable follow-up runtime (Nachlaufzeit) for afterglow for perimeter lighting when coming home. These luminaires are then switched off after the subsequent operating time has elapsed.

When locking a motor vehicle, whether remote locking or keyless locking via the comfort locking function (Komfortschlie β funktion) using radio monitoring technology, this locking operation is indicated by means of flashing lights. This allows the driver of the vehicle to see that the motor vehicle is actually locked due to the activation of the locking function.

Since known motor vehicles have the same functionality in this respect, the relevant processing methods are not suitable for individual-specific or vehicle-specific or manufacturer-specific personalization.

Contents of the invention

In view of this, it is an object of the present invention to provide a method for controlling a luminaire by means of which such an individual-specific or vehicle-specific or manufacturer-specific personalization can be realized easily and uncomplicated.

This object is achieved by the method according to the invention.

An exemplary embodiment of the invention relates to a method for controlling a luminaire of a motor vehicle having a plurality of luminous surfaces, such as in particular headlights or rear lights of a motor vehicle, the luminous surfaces being controlled by one lighting element or by multiple wherein at least several of the luminous surfaces are controlled to light up in a pre-determinable pattern and/or are then controlled to be extinguished in a pre-determinable pattern to signal a pre-defined vehicle state . This enables individualization in predetermined operating states, since the lighting up can be controlled according to an individual pattern and the extinguishing can also be controlled according to a predefined pattern. It is thus possible to assign a pattern which can identify an operating state to a corresponding desired operating state. For example, locking or unlocking of the motor vehicle can be indicated in a defined or individual manner by means of a predefined pattern.

It is particularly advantageous that at least some or all of the luminous surfaces of the daytime running lights and/or parking lights and/or dipped beams are controlled to light up in a preset pattern and/or are then illuminated Controlling extinguishing according to a presettable pattern to send a signal about a predefined vehicle state, and/or at least several or all of the luminous surfaces of a rear light, such as a taillight or a brake light or a parking light, are controlled according to a presettable The pattern lights up and/or is then controlled to turn off in a pre-settable pattern to signal a predefined vehicle state. This enables corresponding, individual control of luminous effects which can be assigned to a vehicle state.

It is advantageous here to control the lighting up followed by the extinguishing, wherein the extinguishing period is longer than the lighting period, in particular the extinguishing period is at least a multiple of the lighting period (Mehrfach).

It is also advantageous here if the luminous surfaces are extinguished jointly or successively. Rapid extinguishing can be achieved by means of this common extinguishing. Alternatively, successive extinguishments can also be controlled. This results in meaningful visual effects.

It is also expedient if the luminous surfaces light up together or one after the other. Rapid lighting can be achieved by means of this common lighting. Alternatively, successive lighting ups can also be controlled. Significant visual effects can also be obtained in this way.

It is particularly advantageous here if the luminous areas of the daytime running lights and/or parking lights and/or dipped beam lights and/or rear lights and/or brake lights are formed as at least four luminous areas, which are substantially divided by Arranged at these corners of polygons, such as especially rectangles. Advantageous here is the arrangement of four luminous surfaces arranged at the corners of the rectangle as dipped beam, daytime running light and/or parking light or as rear light and/or brake light.

It is also advantageous that the luminous surfaces light up from top to bottom or from bottom to top or from right to left or from left to right or circularly and clockwise or counterclockwise, wherein the luminous surfaces light up from top to bottom or from bottom to bottom Turn off up or right to left or left to right or clockwise or counterclockwise in a circle. In this way, individual lighting effects can be obtained which can be changed according to the state of the vehicle.

It is also advantageous if the luminous surfaces are formed as transverse light strips or transverse profiled surfaces. Advantageously, these luminous surfaces are provided, for example, as rear lights and/or brake lights.

It is also advantageous that the luminous surfaces can be illuminated from top to bottom or from bottom to top or from right to left or from left to right or in a circular clockwise or counterclockwise direction, wherein the luminous surfaces can be illuminated from top to bottom Or turn off from bottom to top or from right to left or from left to right or clockwise or counterclockwise in a circle.

It is also advantageous that the luminaire also has at least substantially surrounding luminous surfaces which are controlled to light up in a pre-determinable pattern and/or are then controlled to extinguish in a pre-determinable pattern to signal about Signals of predefined vehicle states. As a result, a surrounding light effect can be obtained in connection with the control of the additional, above-mentioned light-emitting surface.

It is particularly advantageous if the lighting up is controlled with a correspondingly selected light color in response to a signal issued regarding a predefined vehicle state. One of these vehicle states can thus be signaled in one color and another vehicle state can be signaled in another color, for example the unlocked state can be signaled in blue and the unlocked state can be signaled in red or correspondingly also in another color. The color of the light signals the lock status.

It is also advantageous here if the lighting takes place in a color that differs from the light color of the daytime running lights, parking lights and/or dipped beam lights or rear lights or brake lights.

This difference can thus be made clearer by the color selection.

Description of drawings

The invention will be described in detail below with the aid of exemplary embodiments and with reference to the drawings. In the attached picture:

Figure 1 shows a schematic diagram of a luminaire, in particular a headlight of a motor vehicle, and

FIG. 2 shows a schematic view of a luminaire, in particular a rear light of a motor vehicle.

detailed description

FIG. 1 shows a schematic illustration of a light fixture 1 of a motor vehicle, which is formed as a headlight in the exemplary embodiment shown in FIG. 1 . Alternatively, the light fixture can also be formed as a rear light.

As headlights, these lamps have four luminous surfaces 2 , 3 , 4 , 5 as daytime running lights or, where appropriate, also as luminous surfaces for dipped beams. These light-emitting surfaces are arranged at the corners of rectangles or polygons, wherein the light-emitting surfaces themselves are not rectangular, but arranged flat in trapezoidal or drop-shaped shapes.

The main light module 6 for low beam and/or high beam is arranged in the central region of the luminaire 1 . Here, the main light module 6 is formed approximately as a flat, barrel-shaped element. The upper and lower parts of the element are formed flat and both sides are convex. In this case, the corners of the main light module 6 lie approximately on the intersection of the inner corners of the luminous surfaces 2 to 5 of the daytime running lights and/or dipped beams.

A surrounding luminous surface 7 is also provided, which can be formed by a surrounding control part of the luminous element(s) in order to generate surrounding light. In this case, the circumferential luminous areas 7 are formed, for example in FIG. 1 , as essentially uninterrupted luminous areas. Alternatively, the luminous areas can also be formed intermittently, so that there is a distance between the individual luminous elements.

If the lamps are designed as rear lights, the four luminous areas 2 to 5 can be formed, for example, as rear lights or as brake lights. In this case, the luminous area 6 can be formed accordingly as a brake light or as a rear light. The surrounding luminous area 7 can be formed as an aura luminous area, which can belong to a rear light or to a brake light.

In general, a luminous area 2 to 7 consists of one luminous element or a plurality of luminous elements or has one or more such luminous elements, so that when switched on and/or extinguished, either all of a luminous area 2 to 7 The light-emitting elements can be turned on or off at the same time, or at least some of these light-emitting elements can be turned on or off with a time offset.

In order to realize personalization, according to the present invention, at least some of the luminous surfaces 2 to 7 are controlled to light up according to a preset pattern, and then controlled to be extinguished according to a preset pattern, so as to send out information about the preset pattern. Signals of defined vehicle states. This results in a first lighting in which preferably all light-emitting elements light up together or at least several light-emitting elements light up together or at least several or all light-emitting elements are lighted up in a time-staggered manner, followed by at least some or all light-emitting elements. The luminous surfaces or luminous elements are extinguished in a time-staggered manner according to a pattern, in particular according to a predefined pattern.

Wherein, the lighting up can directly reach a preset nominal brightness, or the brightness can be raised with a preset time-delayed ramp-up rate.

In this case, the extinguishing can likewise directly reach a predetermined nominal brightness, such as in particular a switch-off state, or the brightness can be reduced with a predetermined time-delayed ramp-down rate.

According to the invention, the extinguishing can take place according to a spatial pattern, according to which at least some of the luminous surfaces are extinguished temporally offset.

It is also possible to control the luminous elements 13 in such a way that the extinguishing takes place according to a spatial pattern, according to which at least several luminous elements of one luminous surface are extinguished temporally offset from one another, and the luminous elements of the other luminous surface are staggered in time extinguished or extinguished simultaneously.

FIG. 1 shows that the luminous surfaces 2 to 5 are arranged in a rectangular arrangement.

In this case, the luminous elements 2 , 3 , 4 and 5 are advantageously illuminated simultaneously, wherein they are then slowly extinguished. In this case, the extinction lasts longer than the illumination, for example in particular at least twice or five times or ten times or longer.

As an alternative or in addition to the four light spots 2 to 5 , one or more in particular transverse light strips 8 can be provided as luminous surfaces, which are controlled to be switched on and slowly extinguished (see FIG. 2 ). This can be done individually or in addition to the four luminous surfaces 2 to 5 .

The four luminous surfaces 2 to 5 can also be illuminated and then the four luminous surfaces move clockwise or counterclockwise in a circle from top to bottom or from bottom to top or from right to left or from left to right or circularly. The hour hand goes out. If two luminaires are provided on the vehicle, the luminous surfaces of these luminaires are extinguished together or in reverse, ie respectively from the inside to the outside or from the outside to the inside or one counterclockwise and the other clockwise.

The four luminous surfaces 2 to 5 can also light up clockwise or counterclockwise in a circle from top to bottom or from bottom to top or from right to left or from left to right or circularly. If two luminaires are provided on the vehicle, the luminous surfaces of these luminaires light up together or in opposite directions, ie from the inside to the outside or from the outside to the inside or one counterclockwise and the other clockwise.

In this case, the four luminous surfaces 2 to 5 can also be briefly illuminated and then extinguished clockwise or counterclockwise, which can also be regarded as a sweeping extinguishment.

The four luminous surfaces 2 to 5 can also be illuminated one behind the other and then extinguished clockwise or counterclockwise, which can also be regarded as a sweeping extinguishment.

These luminous surfaces can also be illuminated and/or extinguished from the inside to the outside or from the outside to the inside.

Instead of the above-mentioned four light-emitting surfaces, only two of the four light-emitting surfaces (such as the two light-emitting surfaces on the upper part or the two light-emitting surfaces on the lower part or the two light-emitting surfaces arranged diagonally) can also be controlled to be used correspondingly for on and for off.

Instead of the above-mentioned four luminous surfaces, it is also possible to control only three of the four luminous surfaces, correspondingly for lighting up and for going out.

Alternatively, only one of the luminous surfaces can also be controlled for switching on and off.

The above-mentioned controlled behavior may represent and indicate an OFF state and/or a locked state or a brake state or an ON state or other vehicle states.

These luminous surfaces can be illuminated in color according to the vehicle state to be indicated. In this case, when RGB LEDs are used, the colors can be adjusted individually accordingly.
