World’s tiniest light diodes are 100x narrower than a cell
Engineers in Switzerland have built light-emitting diodes so small that hundreds could line up across the width of a single ...
Abstract: A LED driver IC with constant current and temperature compensation is presented. The IC is trimmed to provide constant current of 20mA±5% at an input voltage of 6.0–90V. The IC can be used ...
Abstract: This paper proposes a new current balancing method for alternating current (AC) - light emitting diodes (LED). The proposed method uses the bi-directional current mirror circuit with ...
