20120320595 | LIGHT SOURCE HAVING LED ARRAYS FOR DIRECT OPERATION IN ALTERNATING CURRENT NETWORK AND PRODUCTION METHOD THEREFOR - To allow a direct connection of a light source to a 230V/50 Hz or 120V/60 Hz AC network and to ensure safe operation and easy adaptation to user requirements when mounting, the light source includes a series connection which is connected to a bridge rectifier (GL) and includes at least two LED arrays strands, which have several interconnected individual LEDs, and a pre-resistor, which are arranged on a plate-like, electrically contacting carrier that dissipates heat, has protection against contact and carries the at least two array-LED-strands. For direct operation in an AC voltage supply, the sum of the flow voltages of the LED arrays (U | 12-20-2012 |
