发明名称 CIRCUIT FOR AN LED ARRAY
摘要 <p>A circuit arrangement for an LED array having two or more parallel-connected LED chains (LK 1 , LK 2 , LK 3 ), in each of which at least one LED ( 2 ) is arranged and, when there are two or more LEDs ( 2 ), the latter are connected in series. In each case, the anode sides of the LED chains (LK 1 , LK 2 , LK 3 ) can be coupled to the positive pole of a supply voltage (U&lt;SUB&gt;v&lt;/SUB&gt;) and the cathode sides can be coupled to the negative pole of the supply voltage (U&lt;SUB&gt;v&lt;/SUB&gt;). A regulating arrangement (RA 1 , RA 2 , RA 3 ) for regulating an intended current distribution between the individual LED chains (LK 1 , LK 2 , LK 3 ) is case connected in series with the respective LED chain (LK 1 , LK 2 , LK 3 ).</p>
