<p>An LED light source includes a sub circuit (24) that is connectable via terminals (12,13) to an electronic transformer and to a powered circuit including at least one LED (4). The sub circuit (24) includes a sub circuit rectifier (1a,1b,1c,1d) that is connectable to the transformer (25) and a constant current regulator (7) and a sub circuit capacitor (6) that are connected parallel to the sub circuit rectifier (1a,1b,1c,1d).</p> |
