Constant current LED lamp
A constant current LED lamp is provided with a linear driver circuit for driving multiple light emitting diodes (LEDs), or LED packages including multiple LED chips, connected in series. The driver circuit includes a rectifier circuit, a filter circuit, a stable voltage circuit, and a constant current circuit. The driver circuit allows the aggregate forward voltage drop of all the LEDs connected in series to approach the rectified input voltage to efficiently utilize the AC power from the mains.
