摘要： A shunting pattern on a surface of an LED die comprises an array of metal dots having widths that are on the order of 2Lt-5Lt (where Lt is transfer length) so as not to block a significant amount of light, yet have low contact resistance to the semiconductor current spreading layer. Contact resistance is not significantly reduced with widths greater than 2Lt. Each dot represents a current injection area. For a minimum 2Lt width and 50 square dots per mm2, the top surface area of an LED die will have about 1% of its surface covered by the dots. To cause the current to be evenly distributed over the top surface of the LED, the dots are connected with a grid of very thin metal connectors, having widths much less than 2Lt. In one embodiment, a wire bond electrode is formed near the middle of the top surface of the LED to create a more uniform current distribution.

摘要： A switching circuit arrangement includes a field effect transistor and circuitry for biasing the gate voltage of the field effect transistor, e.g., forcing the gate voltage of the field effect transistor under a certain threshold. Reverse recovery and gate bounce are simultaneously mitigated. The biasing circuitry includes a biasing diode connected in series to the gate of the field effect transistor to bias the gate voltage of the field effect transistor. A clamping field effect transistor unit is connected between the gate of the field effect transistor and the source of the field effect transistor to force the gate voltage of the field effect transistor under a certain threshold.

摘要： The invention relates to an illumination device for embedding data symbols of a data signal into a luminance output of the illumination device. The device includes a LED comprising at least two segments which have a common electrode and are individually controllable. The LED is configured to generate the luminance output in response to a drive signal. The device further includes a controller configured for switching one of the segments on or off in response to the data signal to embed data symbols of the data signal into the light output of the device. One advantage of such an approach is that the proposed device is compatible with conventional LED drivers since no additional electronics for modulating the drive signal are necessary, which enables simple implementation and reduced costs.

摘要： A parallel resonant converter is operated directly from rectified mains. The single-stage power supply copes with present dimmers (such as leading edge dimmers and trailing edge dimmers) and meets EMC standards. The operating scheme allows avoiding exciting 100/120 Hz flicker without using an electrolytic capacitor. This is possible during both full operation and dimmed operation. Deep dimming down to less than 5% is possible and does not require extra power components.

摘要： Resonant gate driver circuits provide for efficient switching of, for example, a MOSFET. However, often an operation of the resonant gate driver circuit does not allow for an application where high switching frequencies are required. According to the present invention, a pre-charging of the inductor of the resonant gate driver circuit is performed. This allows for a highly efficient and fast operation of the MOSFETs.

摘要： An arrangement includes a voltage input, a reactive element connected in series with the voltage input, and an LED light source. The LED light source includes a first LED unit and a second LED unit, each having at least one LED, a controllable switching device to connect the LED units with the reactive element in a low voltage mode and a high voltage mode, and a control unit. The LED light source has a first, higher, forward voltage in the low voltage mode and a second, lower, forward voltage in the high voltage mode. The control unit controls the current through the LED light source by setting the switching device to the low voltage mode when the current, supplied to the LED light source, corresponds to a first threshold value, and by setting the switching device to the high voltage mode when the current corresponds to a second threshold value.
