LeiterplatteCircuit board

Die Erfindung betrifft eine Leiterplatte, die mit Lumineszenzdioden und zu diesen in Reihe geschalteten Strombegrenzungswiderständen bestückt ist.The invention relates to a circuit board equipped with light-emitting diodes and current-limiting resistors connected in series with them.

Eine derartige Leiterplatte wird häufig in Kraftfahrzeugleuchten, z. B. in Bremsleuchten, Rück- und Blinkleuchten oder in im Bereich der Heckscheibe oder im Bereich des Kofferraumdeckels angeordneten Zusatzbremsleuchten, eingesetzt. Die Strombegrenzungswiderstände legen den zulässigen Strom durch die Lumineszenzdioden fest, wobei mehrere Lumineszenzdioden schaltungstechnisch hintereinander- oder parallelgeschaltet sind. Die Strombegrenzungswiderstände sind gewöhnlich in Form bedrahteter Bauelemente oder in Form von SMD (Surface-Mounted-Device)-Widerständen ausgeführt. Dadurch ist die Anzahl der zu bestückenden Bauelemente hoch und die Lei-0 terplatte muß entsprechend groß dimensioniert werden, was insbesondere störend ist bei einem Einsatz dieser Leiterplatte in einer im Bereich der Heckscheibe oder im Bereich des Kofferraumdeckels angeordneten Zusatzbremsleuchte, da die geometrischen Ausmaße dieser Zusatzbremsleuchte die Sicht eines Autofahrers beeinträchtigen.Such a circuit board is often used in vehicle lights, e.g. in brake lights, tail lights and indicator lights or in additional brake lights arranged in the area of the rear window or in the area of the trunk lid. The current limiting resistors determine the permissible current through the LEDs, with several LEDs being connected in series or in parallel. The current limiting resistors are usually designed in the form of wired components or in the form of SMD (Surface Mounted Device) resistors. As a result, the number of components to be fitted is high and the circuit board must be dimensioned accordingly, which is particularly problematic when this circuit board is used in an additional brake light arranged in the area of the rear window or in the area of the trunk lid, since the geometric dimensions of this additional brake light impair the driver's vision.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Leiterplatte der eingangs genannten Art mit platzsparendem Aufbau anzugeben. Darüber hinaus soll die Leiterplatte insbe-0 sondere in der Automobiltechnik für hochgesetzte, vorzugsweise im Bereich der Heckscheibe oder im Bereich des Kofferraumdeckels angeordnete Bremsleuchten geeignet sein.The present invention is based on the object of specifying a circuit board of the type mentioned at the beginning with a space-saving design. In addition, the circuit board should be suitable in particular in automotive technology for high-mounted brake lights, preferably arranged in the area of the rear window or in the area of the trunk lid.

Diese Aufgabe wird im Hinblick auf die Leiterplatte durch die im kennzeichnenden Teil des Anspruchs 1, im Hinblick auf die Kraftfahrzeugleuchte durch die im kennzeichnenden Teil des Anspruchs 5 angegebenen Maßnahmen gelöst.This object is achieved with regard to the circuit board by the measures specified in the characterizing part of claim 1, and with regard to the motor vehicle lamp by the measures specified in the characterizing part of claim 5.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention emerge from the subclaims.

Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung veranschaulicht ist, werden im folgenden die Erfindung, deren Ausgestaltungen sowie Vorteile näher erläutert.The invention, its embodiments and advantages are explained in more detail below with reference to the drawing, in which an embodiment of the invention is illustrated.

Es zeigen:Show it:

Figur 1 ein Prinzipschaltbild einer Leiterplatte und Figur 2 ein Schaltbild einer Zusatzbremsleuchte.Figure 1 is a schematic diagram of a circuit board and Figure 2 is a circuit diagram of an additional brake light.

In Figur 1 ist mit 1 eine streifenförmige Leiterplatte bezeichnet, welche mit Lumineszenzdioden 2 und Strombegrenzungswiderständen bestückt ist. Weitere Bestandteile der Leiterplatte, wie z. B. Anschlüsse für eine Stromversorgung oder Leiterbahnen, sind für die Erfindung unwesentlich und werden daher nicht näher beschrieben. Die Strombegrenzungswiderstände sind jeweils aus einer Widerstandspaste realisiert, mit einem Schutzlack abgedeckt und auf einer Fläche 3 auf der Leiterbahnseite der Leiterplatte Iz. B. im Siebdruckverfahren aufgedruckt, wodurch ein platzsparender Aufbau der Leiterplatte 1 ermöglicht wird und die Breite der Leiterplatte lediglich von der Breite der Lumineszenzdioden 2 abhängt. In einem praktischen Ausführungsbeispiel der Erfindung beträgt die Breite der Leiterplatte lediglich 1/40 der Leiterplattenlänge. Dabei sind vier in Reihe geschaltete Parallelschaltungen vorgesehen, die jeweils sechs Lumineszenzdioden umfassen. Durch diesen platzsparenden Aufbau ist die Leiterplatte für einen Einsatz in Kraftfahrzeugleuchten geeignet, z. B. in Bremsleuchten oder in Rück- und Blinkleuchten, wobei entsprechende Reflektoren über den Lumineszenzdioden 2 angeordnet sind. Vorzugsweise in einer im Bereich der Heckscheibe oder im Bereich des Kofferraumdeckels angeordneten Zusatzbremsleuchte ist eine derartige Leiterplatte verwendbar, weil durch die geringen geometrischen Ausmaße der Leiterplatte und somit der Zusatzbremsleuchte die Sicht eines Autofahrers wenig beeinträchtigt wird.In Figure 1, 1 designates a strip-shaped circuit board, which is equipped with LEDs 2 and current limiting resistors. Other components of the circuit board, such as connections for a power supply or conductor tracks, are not essential for the invention and are therefore not described in more detail. The current limiting resistors are each made from a resistance paste, covered with a protective varnish and printed on a surface 3 on the conductor track side of the circuit board I, e.g. using a screen printing process, which enables a space-saving construction of the circuit board 1 and the width of the circuit board depends only on the width of the LEDs 2. In a practical embodiment of the invention, the width of the circuit board is only 1/40 of the circuit board length. Four parallel circuits connected in series are provided, each of which contains six LEDs. This space-saving construction makes the circuit board suitable for use in motor vehicle lights, e.g. B. in brake lights or in tail and indicator lights, with corresponding reflectors arranged above the light-emitting diodes 2. Such a circuit board can preferably be used in an additional brake light arranged in the area of the rear window or in the area of the trunk lid, because the small geometric dimensions of the circuit board and thus of the additional brake light have little impact on the driver's vision.

GR 95 G 4445 DE .··.GR 95 G 4445 DE .··.

Im übrigen ist die Widerstandspaste leicht auf die Leiterplatte aufdruckbar und mit dem Schutzlack einfach abzudecken. Dieser Arbeitsgang wird vorzugsweise während der Herstellung der Leiterplatte mit ausgeführt, wodurch eine nachträgliche Bestückung der Leiterplatte entfällt.Furthermore, the resistance paste can be easily printed onto the circuit board and simply covered with the protective varnish. This process is preferably carried out during the production of the circuit board, which eliminates the need for subsequent assembly of the circuit board.

Die Leiterplatte 1 weist vier Gruppen (in der Figur ist nur eine Gruppe dargestellt) von jeweils sechs aus einer Lumineszenzdiode 2 und einem Strombegrenzungswiderstand bestehenden Serienschaltungen auf, die innerhalb dieser Gruppen parallelgeschaltet sind, wobei diese vier Parallelschaltungen wiederum in Serie geschaltet sind. Die Strombegrenzungswiderstände sind so dimensioniert, daß einerseits der maximale Strom durch die Lumineszenzdiode fließen kann und andererseits bei Ausfall von zwei Lumineszenzdioden 2 innerhalb einer der Parallelschaltungen der Strom in dieser Parallelschaltung derart ansteigt, daß die restlichen Lumineszenzdioden 2 der Parallelschaltung zerstört werden und dadurch der Stromfluß unterbrochen wird.The circuit board 1 has four groups (only one group is shown in the figure) of six series circuits each consisting of a light-emitting diode 2 and a current-limiting resistor, which are connected in parallel within these groups, whereby these four parallel circuits are in turn connected in series. The current-limiting resistors are dimensioned in such a way that, on the one hand, the maximum current can flow through the light-emitting diode and, on the other hand, if two light-emitting diodes 2 within one of the parallel circuits fail, the current in this parallel circuit increases to such an extent that the remaining light-emitting diodes 2 in the parallel circuit are destroyed and the flow of current is thus interrupted.

Zur Verdeutlichung der Funktions- und Wirkungsweise der Stromunterbrechung wird auf Figur 2 verwiesen, in der ein Schaltbild einer Zusatzbremsleuchte dargestellt ist. Die in den Figuren 1 und 2 vorkommenden gleichen Teile sind mit gleichen Bezugszeichen versehen. Die Schaltung weist Versorgungsanschlüsse 5 und vier in Serie geschaltete Parallelschaltungen 6a bis 6d auf, die jeweils sechs Serienschaltungen 7a bis 7f umfassen. Jede dieser Serienschaltungen 7a bis 7f besteht aus einer Lumineszenzdiode 2 und einem Strombegrenzungswiderstand 8. Da die Parallelschaltungen 6a bis 6d gleich aufgebaut sind, ist der Einfachheit halber in der Figur lediglich die Parallelschaltung 6a vollständig dargestellt, die Parallelschaltungen 6b bis 6d nur als Funktionsblock. Wie erläutert, sind die Strombegrenzungswiderstände so dimensioniert, daß einerseits der maximale Strom durch die Lumineszenzdiode fließen kann und andererseits bei Ausfall von zwei Lumineszenzdioden 2 innerhalb einer der Parallelschaltungen 6a bis 6d der Strom in dieser ParallelschaltungTo clarify the function and operation of the current interruption, reference is made to Figure 2, which shows a circuit diagram of an additional brake light. The identical parts appearing in Figures 1 and 2 are provided with the same reference numerals. The circuit has supply connections 5 and four parallel circuits 6a to 6d connected in series, each of which comprises six series circuits 7a to 7f. Each of these series circuits 7a to 7f consists of a light-emitting diode 2 and a current-limiting resistor 8. Since the parallel circuits 6a to 6d are constructed in the same way, for the sake of simplicity only the parallel circuit 6a is shown in full in the figure, the parallel circuits 6b to 6d only as a functional block. As explained, the current limiting resistors are dimensioned so that, on the one hand, the maximum current can flow through the luminescent diode and, on the other hand, if two luminescent diodes 2 fail within one of the parallel circuits 6a to 6d, the current in this parallel circuit

GR 95 G 4445 DEGR 95 G 4445 DE

derart ansteigt, daß die restlichen Lumineszenzdxoden 2 der Parallelschaltung zerstört werden und dadurch der Stromfluß unterbrochen wird und die Leuchte ausfällt.increases to such an extent that the remaining luminescence diodes 2 of the parallel circuit are destroyed, thereby interrupting the flow of current and causing the lamp to fail.
