Latest Patents

One of Nishitani's latest patents is an LED drive device that effectively drives and lights an LED. This device includes a power conversion unit that converts the voltage of a first power supply to supply it to the LED. Additionally, it features a second power supply with a voltage lower than the LED's threshold voltage. A current generation unit generates current using the voltage from the second power supply and supplies it to the LED's anode. Furthermore, a ground-fault detection unit determines whether a ground fault occurs at the LED's anode based on the current flow from the current generation unit.

Another notable patent is for a lighting apparatus that includes a drive section applying electric current to a semiconductor light source. This apparatus is equipped with at least one heat sink that transfers heat generated by the light source. A temperature measurement section is mounted to the heat sink to measure its temperature, which helps estimate the temperature of the light source. The design allows the light source and drive section to be mounted on the same heat sink or on thermally coupled heat sinks.
