Latest Patents

Kinoshita holds a patent for a light source lighting device that includes a constant-current supply connected to a light source. This device supplies a constant current of a substantially constant magnitude to the light source. The patent describes a power supply circuit that drives circuits with different numbers of series-connected LEDs without altering circuit constants or components. The LED series circuit is linked to a power converter circuit, which is controlled by a control arithmetic circuit. This circuit supplies a constant current to the LED series circuit and detects the voltage applied to it. The control arithmetic circuit determines whether the LED series circuit contains 40 or 20 LEDs based on the detected voltage. It maintains constant-current value tables for both configurations and selects the appropriate one based on the voltage detected.
