The present invention relates to a light, a switch-type intelligent
light control terminal, and a switch-type intelligent
light control system and method. The control terminal comprises a
communication unit, a terminal
control unit, a
relay, a
relay control unit and a power supply. The switch of the
relay is connected in series in a controlled light or the power supply loop of a light set; the relay
control unit comprises a
triode, one end of the coil of the relay is connected with the power supply, the other end of the coil of the relay is connected with a
triode collector, the base
electrode of the
triode is connected with the output end of the terminal control unit, and the emission
electrode of the triode is earthed. A control host is arranged to send control signals to the control terminal through
wireless transmission or cables, the control terminal is connected with the controlled light or the light set into one body to ensure the remote
reliable transmission of the control signals, realize uniform control of the LED light or a light having a DMX512
control function, realize point-to-point control and realize point-to-line and point-to-surface control so as to eliminate a console with
heavy weight, large
power consumption and bad reliability, and therefore the light, the switch-type intelligent
light control terminal, and the switch-type intelligent light
control system and method are suitable for outdoor or
stage lighting control.
