1.1 line system comparison
(1) Comparison of single control circuit systems. Traditional lighting single control circuit features:
a. The control switch is directly connected to the load circuit;
b. When the load is large, the capacity of the control switch should be increased accordingly;
c. When the switch is far away from the load, the amount of large-section cable is increased;
d. Only a simple switching function can be realized.
Bus-type intelligent lighting system single control circuit features:
a. The load circuit is connected to the output of the output unit, and the control switch is connected to the output unit by the EIB bus. When the load capacity is large, only consider increasing the capacity of the output unit, and the control switch is not affected;
b. When the switch distance is long, only the length of the control bus must be lengthened to save the amount of large-section cable;
c. Various functions (on/off, dimming, timing, etc.) can be set by software.
(2) Comparison of dual control circuit systems. Traditional lighting dual control circuit features: a. When implementing dual control, use two single-pole dual-position switches, and connect the lighting cables between the switches;
b. When the multi-point control is performed, the cable connection between the switches increases, which makes the installation of the circuit very complicated and the construction difficulty becomes more difficult.
Bus-type intelligent lighting system dual control circuit features:
a. When implementing dual control, it is only necessary to connect a switch in parallel on the control bus;
b. When performing multi-point control, multiple switches are connected in parallel, and only one bus is connected between the switches, and the line installation is simple and trouble-free.
1.2 Comparison of intelligent lighting and traditional lighting control systems
(1) Comparison of control methods.
a. The traditional control uses a manual switch and must be turned on or off all the way;
