How do you differentiate between centralized control and sub control in the sensor switches of cabinet lighting systems?

With the continuous upgrading of smart homes and custom cabinets, cabinet lighting systems have evolved from "basic lighting" to "experiential lighting." In these lighting systems, the choice of control method for the sensor switch, as the core control unit, is particularly crucial. Among them, centralized control and distributed control are the two most widely used solutions.

What are centralized control and sub control?

Centralized control system

Centralized control system means that multiple light groups are managed uniformly through one controller (centralized control switch). Any sensor trigger will activate a linked response across the entire system. The centralized control switch controls the output of the entire transformer, and is not affected by the total power of the lamps. The power is the power of the transformer, and the number of lamp interfaces is the number of interfaces on the transformer's output end. One centralized control sensor switch can also be linked to control multiple power supplies simultaneously.

This centralized control solution has clear wiring and simple installation, making it ideal for scenarios requiring entire rows or overall linked lighting, such as kitchen cabinet main light strips and overall display cabinets.

Sub control system

Sub control system, on the other hand, emphasizes the independent operation of each light group or sensing unit, meeting the needs of local lighting and refined use. Simply put, a sub control sensor switch only controls one interface at its own output end, with a maximum power of 60W (12V) or 120W (24V). If the total power of the lamps is overloaded, a power amplifier needs to be added.

This distributed control solution is suitable for local lighting systems, such as different shelf heights or partitioned lighting environments within cabinets. Users only need to illuminate the current area, significantly improving convenience and energy efficiency.
