High lpw efficiency cob and light engine including the same

Abstract

A high-lumens-per-watt (LPW) efficiency light engine includes a power supply configured to receive an AC input signal and to generate a rectified signal; a light driver configured to generate a drive signal based on the rectified signal, the drive signal having a voltage of about 100 V to about 485 V; a light source including a high-voltage chip-on-board (COB) light configured to emit light based on the drive signal, the high-voltage chip-on-board (COB) light including a first power terminal, a second power terminal, and a plurality of LED chips coupled between the first and second power terminals, the drive signal being applied across the first and second power terminals; and a housing configured to encapsulate the power supply, the light driver, and the light source and to provide electromagnetic interference (EMI) shielding of circuitry of the light engine from the outside.
