Definitions

  • the present invention relates to a method of reducing the pulsation rate of the luminous brightness following the alternating current power voltage of an electric-driven luminous body which directly uses alternating current power by means of polyphase-driven electric energy.
  • the present invention relies on polyphase alternating current power with phase difference or direct current power rectified from polyphase alternating current power to drive a common -electric-driven luminous body, or to separately drive adjacently installed individual electric-driven luminous bodies so that the pulsation of the outwardly projected light is reduced.
  • a lighting device with optical pulsation suppression for use with a polyphase power supply comprises: a first input power line for connection to a first of three phases; a second input power line for connection to a second of three phases; a third input power line for connection to a third of three phases; a direct current electric luminous body; a first single phase bridge rectifier connected to the first input power line; a second single phase bridge rectifier connected to the second input power line; a third single phase bridge rectifier connected to the third input power line; a first current limit component connected in series with the first rectifier; a second current limit component connected in series with the second rectifier; and a third current limit component connected in series with the third rectifier, wherein each direct current output end of the rectifiers are connected to the direct current electric luminous body.
  • the present invention relies on polyphase alternating current power with phase difference or direct current power rectified from polyphase alternating current power to drive a common -electric-driven luminous body, or to separately drive adjacently installed individual electric-driven luminous bodies so that the pulsation of the outwardly projected light is reduced.
  • FIG. 1 is the optical pulsation oscillogram of the traditional single phase alternating current power or alternating current full wave-rectified direct current directly driving the electric-driven luminous body.
  • a is alternating current power wave form
  • b is wave form of direct current rectified from alternating current
  • c is optical pulsation wave form of electric-driven luminous body; if the electric energy input is a bidirectional pulsating electric energy with a bidirectional non-sinusoidal wave, the improvement function is also the same.
  • FIG. 2 is the circuit diagram in which each phase of the three-phase alternating current power being individually connected in parallel with a circuit device in series connected by the current limit component (Z10) and the alternative current terminal of single-phase bridge rectifier, then the direct current output terminal of the single-phase bridge rectifier of each phase being homo-polar connected in parallel for jointly driving the direct current electric-driven luminous body (2000); as shown in FIG. 2 , it mainly consists of:
