Latest Patents
One of Gielniewski's latest patents is titled "Color mixing for solid state lighting using direct AC drives." This invention describes techniques that enable low-cost light fixtures to produce light with a high color rendering index (CRI) across various color temperatures. The system utilizes a rectified AC voltage supplied to multiple groups of light-emitting diodes (LEDs), which are controlled based on a received control signal. This allows the combined groups of LEDs to produce light with a desired color temperature and CRI level.
Another significant patent is the "Analog circuit for color change dimming." This analog-based dimmable LED lighting system consists of several LED lighting modules that emit light at different correlated color temperature (CCT) ranges. Each module is powered by a common dimming signal in the form of an AC voltage, which corresponds to a specific dimming level. The system includes an analog rectifier bridge and an analog current limiter to control the current through the LEDs, enabling the production of light at a selected CCT and intensity.
