Latest Patents

Nomoto's latest patents include innovative designs for discharge lamp operating circuits. One of his patents describes a discharge lamp operating circuit that comprises two series circuits, each including two switching devices, connected in parallel with the power supply. This circuit also includes a series circuit with a choke coil, a first capacitor, and a parallel circuit with a discharge lamp and a second capacitor. The design allows for the discharge lamp to be turned on and off by alternately activating the switching devices. The timing for switching is set to occur when the current flowing through the devices is nearly at zero, enhancing efficiency.

Another patent focuses on a discharge lamp operating circuit that includes a discharge lamp, a condenser, and four switches. In this design, the condenser is charged and discharged through the discharge lamp by the operation of the switches, allowing an AC current to flow through the lamp. The time required for the complete charging and discharging of the condenser is longer than the scheduled time for one period, ensuring optimal performance. The relationship between the switching frequencies during heating and operation phases is also defined, contributing to the effective functioning of the discharge lamp.
