| 摘要 |
An illumination device based on a light emitting diode, comprising: a rectification alternating current power supply (601) connecting a rectification output to a storage capacitor (606) via a switch element (604); a plurality of light emitting diode segments (610, 620) controlled by a linear drive circuit (602); and at least one charging path connected between the plurality of light emitting diode segments (610, 620) and the storage capacitor (606). One or more controllable linear light emitting diode drive units (706, 707) are connected to the storage capacitor (606) in parallel to provide balance between reducing light flicker and increasing power. |
