20090021182 | LED DRIVER CIRCUIT - The present invention relates to a low cost LED driver module comprising a switched-mode power supply (smps) having down-converting characteristics ( | 01-22-2009 |
20090230875 | METHOD AND A DRIVER CIRCUIT FOR LED OPERATION - In a method and a driver circuit for operating one or more light emitting diodes, LEDs, an alternating supply current is generated and transformed to an alternating secondary winding voltage. Using rectifier means, such as diodes or synchronous switches, the alternating secondary winding voltage is converted to a substantially constant load current by using a buffer element, such as an output choke, i.e. a suitable inductor. The power transferred from the power source to the LEDs may be controlled by frequency control of the alternating supply current. | 09-17-2009 |
