Off-line voice light control system

An off-line voice light control system, comprising:

• a pickup unit for picking up a voice signal of a user;
• a voice recognition unit configured to parse the voice signal and output a command signal, wherein the voice recognition unit is electrically connected to the pickup unit;
• a lighting mode switching unit for generating a lighting mode signal after parsing the command signal provided by the voice recognition unit, wherein the lighting mode switching unit is electrically connected to the voice recognition unit;
• and
• a switch unit (A) controlled by the lighting mode signal to be enabled and disabled, wherein the switch unit (A) is electrically connected to the lighting mode switching unit;
• wherein
• the off-line voice light control system further comprises a step-down direct-current power conversion chip (U3), a fly-wheel diode (D1), a first inductor (L1) and a second capacitor (C2) that are configured to store energy, an output end of the step-down direct-current power conversion chip (U3) is respectively connected to a cathode terminal of the fly-wheel diode (D1) and one end of the first inductor (L1), an anode terminal of the fly-wheel diode (D1) is grounded, the other end of the first inductor (L1) is respectively connected to one end of the second capacitor (C2), the voice recognition unit, and the lighting mode switching unit, and the other end of the second capacitor (C2) is grounded.
