Single-ended primary inductance converter (SEPIC) based power supply for driving multiple strings of light emitting diodes (LEDs) in roadway lighting fixtures |
摘要 |
A lighting fixture and power supply are provided that allows a power factor correction (PFC) single ended primary inductance controller (SEPIC) that provides a controlled voltage output to provide a constant current to an LED load. The power supply provides an efficient and stable power supply for LEDs. Multiple power supplies can be provided on the same printed circuit board to control multiple LED channels. |
