Multi-level LED lighting system with power-cycle-based current regulation

PCT designated stageWO2026139730A1MOSFETCurrent driver
Abstract the embodiments herein provides a solid-state lighting apparatus and method enable multi-level power control of LED luminaires without digital controllers, data lines or mechanical relays. A constant-current driver feeds the LED load through a current-sense network that includes a fixed base resistor and at least one series step resistor. Each step resistor is bridged by an optically-isolated MOSFET shunt. An analogue detector recognises an AC-mains interruption of three-to-six seconds and, on each re-energisation, activates a further shunt in sequence, thereby lowering the effective sense resistance and increasing the regulated LED current. Zero-cross gating minimises electromagnetic interference. The architecture provides at least three discrete lighting levels over a 5 W-to-300 W range, delivers flicker-free output, and can be retrofitted into existing street, industrial or residential fixtures using only the native power wiring.
