Direction indicator circuit for controlling a direction indicator in a vehicle |
摘要 |
A direction indicator circuit for controlling a direction indicator may include: a first terminal for connecting to a supply voltage terminal; a second terminal for connecting to a direction indicator switch and a lighting means; a third terminal for connecting to a capacitor; wherein the direction indicator circuit is designed to provide the lighting means with a current during an on state and with no current during an off state, wherein the duration of the on state and the duration of the off state are determined by a voltage at the capacitor; wherein the direction indicator circuit has a first and a second circuit, wherein the capacitor provides the supply voltage for the first and second circuits during the on state; wherein the current which flows through the first circuit has a negative temperature coefficient, and the current which flows through the second circuit has a positive temperature coefficient. |

1. A direction indicator circuit for controlling a direction indicator in a vehicle, the direction indicator circuit comprising:
a first terminal for connecting to a supply voltage terminal; a second terminal for connecting to a direction indicator switch and a lighting means; a third terminal for connecting to a capacitor; wherein the direction indicator circuit is designed to provide the lighting means with a current during an on state and with no current during an off state, wherein the duration of the on state and the duration of the off state are determined by a voltage at the capacitor; wherein the direction indicator circuit has a first and a second circuit, wherein the capacitor provides the supply voltage for the first and second circuits during the on state; wherein the current which flows through the first circuit has a negative temperature coefficient, and the current which flows through the second circuit has a positive temperature coefficient, wherein the second circuit comprises a power source, wherein the current of said power source is derived in such a way that the current has a positive temperature dependence. |
