Solution Overview
Problem
LED lighting systems face inefficiencies due to varying power usage and exceeding maximum power output, leading to suboptimal energy efficiency and potential overloads, especially when multiple LED modules are connected, and existing systems lack adaptive control to match power sources with demand.

1Area of stationary object
If multiple LED modules are connected to increase lighting coverage, then the lighting area is expanded, but the power load may exceed the maximum output power of the power supply
Solution Approach 1:
The power supply system is segmented into multiple independent power source units (first power source unit, second power source unit, etc.), each capable of supplying power to LED modules. This allows the total power load to be distributed across multiple units, enabling expansion of lighting area without overloading a single power supply.
Solution Approach 2:
The system dynamically activates or deactivates power source units based on the actual power consumption requirements. The cluster controller collects power consumption information from LED controllers and adjusts the number of active power source units in real-time, allowing the power supply capacity to adapt to the current lighting area and load requirements.
2Power
If the power supply output is increased to meet high power demands, then the power capacity is sufficient, but the energy efficiency decreases when fewer LED modules are connected
Solution Approach 1:
The system transitions from a static power supply configuration to a dynamic one where power source units are activated or deactivated based on real-time power consumption data. This allows the power capacity to match the actual demand, maintaining high energy efficiency whether few or many LED modules are connected.
Solution Approach 2:
The system changes the operational parameters (number of active power source units) based on the power consumption requirements. When power consumption is low, fewer power source units are activated; when power consumption is high, more units are activated, thereby optimizing energy efficiency across different operating conditions.
3Device complexity
If a single power source unit is used to simplify the system, then the device complexity is reduced, but the system cannot adapt to varying power usage demands
Solution Approach 1:
The power supply system is divided into multiple modular power source units that can be independently controlled. This segmentation enables the system to adapt to varying power demands by activating only the necessary number of units, while the modular design keeps individual unit complexity manageable.
Solution Approach 2:
LED controllers transmit power consumption information to the cluster controller, which uses this feedback to determine how many power source units should be activated. This closed-loop feedback mechanism enables adaptive control without requiring complex manual configuration or oversimplified fixed-capacity power supply.
4Power
If multiple power source units are activated to meet high power demands, then the power capacity is sufficient, but the energy efficiency of individual power source units decreases
Solution Approach 1:
Instead of always activating all power source units, the system dynamically determines the optimal number of units to activate based on actual power consumption. This ensures that power source units operate at or near their optimal efficiency range, avoiding the energy efficiency degradation that occurs when units operate at low load.
