WebThe DCS Controller Triple Output is an advanced LED lighting controller that allows for the independent control of up to three lighting channels. It features both constant current and constant voltage modes of operation, making it compatible with a wide range of LED lights. WebA light releasing diode is an electric component which emits light when the electric current flows through it. Further, it is a light source which is on the basis of semiconductors. When current passes through the LED, the electrons recombine with holes and emit light in this procedure. It is a particular kind of diode which has the same type ...
