Abstract

The rear light (1) has two multi-colored light sources arranged in multiple light chambers (3). The light sources are controllable by a signal associated to an operating condition i.e. intensity of braking, of a motor vehicle (2) and by a signal initiated by a driver. The light sources are designed as red, orange or white colored LEDs, and the chambers are designed as brake lights (7). The signal associated to the operating condition of the motor vehicle is designed as a brake signal, a reverse movement signal or a direction indication signal. The signal initiated by the driver is designed as a warning light signal, a nebula closure lighting signal or a parking light signal.

Description

The The invention relates to a tail lamp of a motor vehicle. It concerns further a motor vehicle with such a taillight.

From the DE 103 37 411 A1 is a so-called third brake light known, which is arranged in the region of a vehicle rear. It is controlled in response to signals from a speed measuring device and a braking device and makes it possible to also display the intensity of the braking.

It On the one hand there is a need to change the operating state of a Vehicle, such as the intensity of braking, other road users as differentiated as possible signal. On the other hand, such signals must also be so easy and intuitive that they understood easily and quickly become.

task The invention is therefore a tail lamp for a vehicle indicate clearly with the operating conditions of the vehicle and are easy to visualize, but which is technically easy to implement.

According to the invention this object with the subject of the independent claim solved. Advantageous further education applications of the invention are Subject of the dependent claims.

A Rear light according to the invention of a motor vehicle includes several, d. H. at least two chambers, being in a number of chambers arranged at least two different colored light sources are. The light sources of at least one chamber are by an operating condition the motor vehicle associated signals and by a driver triggered signals triggered.

Under a tail light is here and below the system of lights conventionally, in addition to the tail light Also, for example, turn signals, brake lights and rear fog lights includes.

Under A chamber is here and below a subsystem of the tail light understood, in which several light sources grouped into a functional unit are. The outgoing from a chamber light signal is in a typical embodiment perceived as a unit. In an advantageous embodiment, the chambers formed by body regions separated from each other, that is, the individual chambers are limited by body areas.

The Rear light according to the invention has the advantage that at least those chambers that several different colors Have light sources, can be used multiple times and depending on the control, for example, either red or white or emit orange light. That's it possible, with little technical effort and low Space consumption differentiated optical signals of the tail light enable. For example, the invention requires Rear light does not have more space than a conventional, but can because of the multiple occupancy of the individual chambers with different colors Light sources more different signals with high luminous intensity implement.

The Light sources of at least one chamber are both by an operating condition the motor vehicle associated signals as well as by a Driver triggered signals controllable, wherein the one operating state associated signals such as brake signals or reverse lights and the signals caused by a driver, for example Turn signals, hazard lights or rear fog lamp include. In addition, those initiated by the driver Signals a parking light and / or a signal to indicate the operation be a vehicle lock.

There the light sources at least one chamber both by an operating condition associated signals as well as caused by a driver signals can be controlled, this chamber can be repeatedly occupied and, for example both as a brake light and as a turn signal to indicate a change of direction serve.

In In one embodiment, the light sources are light-emitting diodes educated.

Especially the tail light has red, orange and white light sources on how they are used for rear lighting in motor vehicles are known.

In In one embodiment, a series of chambers is one above the other left and another row of chambers one above the other right arranged from the rear window. The lowest chamber of each row can each white and red light sources and the other Chambers of each row have red and orange light sources.

at Such a configuration may be the lowest chambers as fog and reverse lights be used and the remaining chambers as turn signals and Brake lights.

In an advantageous embodiment, all have right and left of the rear window arranged chambers on at least two different colored light sources and can thus be used multiple times.

In In one embodiment, at least one chamber is third Stop lamp designed and centrally located in the rear window or above.

embodiments The invention will be described below with reference to the attached Figures explained in more detail.

1 schematically shows a tail lamp according to an embodiment of the invention;

2 shows schematically the equipping of the chambers of the tail light with different colored light sources and

3 schematically shows a circuit diagram for the tail light according to 2 ,

Same Parts are provided in all figures with the same reference numerals.

The tail light 1 according to 1 is in the area of the rear of a motor vehicle 2 arranged. It has a number of chambers 3 on that in the rear of the motor vehicle 2 taken in and through body areas 4 are separated from each other.

The chambers 3 are in a row 5 to the left of the rear window 10 and in another row 6 right from the rear window 10 arranged. In addition, another chamber 3 as the third brake light 7 trained and in the upper part of the rear window 10 arranged.

In the illustrated embodiment are in each chamber 3 except in the third brake light 7 trained chamber 3 arranged at least two different colored LEDs as light sources.

An example of the assembly of the chambers 3 with different colored light emitting diodes is in 2 shown, with each row here 5 . 6 only seven chambers 3 having.

The individual chambers 3 are numbered from L1 for "first chamber of the left row" to R7 for "seventh chamber of the right row". The respective equipment with LEDs is listed next, where "0" stands for "orange", "R" for "red" and "W" for "white". Accordingly, in this embodiment, all the chambers 3 the series 5 and the further series 6 equipped with red and orange LEDs except for the lowest chamber 8th . 9 these rows, which have white and red LEDs. The third brake light 7 is only equipped with red LEDs.

3 shows an example of a technical implementation of the tail light 1 , In this case, light emitting diodes with lambertian radiation characteristics and a power of 3 watts are used and in each case the red and orange LEDs of three chambers 3 a row 5 . 6 supplied with a common high-performance constant current source, each with, for example, 1400 mA and controlled pulse width modulated with a frequency of 2500 kHZ. The light-emitting diodes of the lowest chamber 8th . 9 a row 5 . 6 are powered by their own high-performance constant current source with 1400 mA for the red and 1500 mA for the white LED.

With the tail light according to the invention 1 the following signals can be output:

Direction indicator

For the signal "turn signal left", the LEDs L1-6O, so the orange LEDs of the upper six chambers 3 the left row 5 , driven.

For the signal "turn signal right", the LEDs R1-6O, ie the orange LEDs of the upper six chambers 3 the right row 6 , driven.

hazard lights

For this purpose, the light-emitting diodes L1-6O and R1-6O, so the orange LEDs of the upper six chambers 3 every row 5 . 6 , flashing activated.
