Embodiment Construction

[0026] These examples are preferred implementation forms of the invention.

[0027] exist figure 1 Shown in is the interior of the blinker 10 . The blinker 10 is built into a rear light of a passenger car. A printed circuit board 14 (Printed Circuit Board—PCB) is located in the blinker 10 , on which a total of twenty-three light-emitting diodes 16 are soldered. For clarity, figure 1 Only one of the light-emitting diodes 16 in has a reference numeral. Here, the light emitting diodes 16 are arranged in a straight line on the printed circuit board 14 . The circuit board 14 is located behind the orange transparent glass in the blinker. The light of the light-emitting diodes 16 therefore appears orange to the observer from the outside. Instead of a single printed circuit board 14 , it is also possible to distribute the light-emitting diodes over several printed circuit boards.

[0028] The printed circuit board 14 is connected to the control unit 20 via a plurality of wires ...

Abstract

The invention relates to a motor vehicle flashing signal light which can highlight a driving direction to be indicated through changing light effects. But not all countries allow indicating a change of the driving direction by means of changing light. The invention aims to improve indication of the change of the driving direction for a motor vehicle. For this purpose, according to the invention, an LED flashing signal light (10) is operated through the following method: in a flashing cycle, starting from a switched-off state of all LED groups (24-32) of the flashing signal light, a primary group (24) is switched on at first, and subsequently the other LED groups (26-32) are successively switched on until all the LED groups (24-32) are switched on. The LED groups (24-32) are maintained in a switched-on state for a predetermined time period and are finally switched off. The time period from activation of the primary group (24) until reaching the active state of all LED groups (24-32) lies in the range of 100 milliseconds to 200 milliseconds.

Description

technical field [0001] The invention relates to a motor vehicle blinker with a plurality of light emitting diodes (LED-Light emitting diodes) arranged in a row. The invention also relates to a method for operating a blinker, in which a plurality of LED groups each comprising at least one light-emitting diode are arranged in a row. Background technique [0002] Strobe lights of this type are known, for example, from DE 101 30 259 A1 and US 2009 / 0051523 A1. [0003] Strobe lights, or simply flashers / turn signals, are used in motor vehicles as direction indicators. The blinkers are alternately switched on and off within a flash cycle, that is, each flash cycle consists of an active period (during which the blinker lights up) and an inactive period (during which the blinker remains dark) . Here, the flash frequency is between 1 Hz and 2 Hz. For flashing lights to be permitted in road traffic, certain legal framework conditions must be fulfilled here. It must therefore be vi...
