发明名称 Direct Current Driving Circuit of a Light Emitting Device
摘要 The invention provides a direct current driving circuit of a light emitting device for driving a plurality of light emitting devices. The direct current driving circuit of the light emitting device comprises a rectification unit, a constant current unit and a light emitting module. The rectification unit is configured to rectify an outside alternate current voltage to output a direct current voltage. The constant current unit is electrically connected to the rectification unit, and generates a direct current corresponding to the direct current voltage to drive the light emitting module. The light emitting module comprises a plurality of light emitting devices and at least one diode connected in serial, and the light emitting devices are respectively connected in parallel to voltage stabilizing capacitances. The driving circuit can provide stabilized direct current load driving with high efficiency and high power factor.
