LED control system suitable for different types of power sources

An LED control system, comprising:

• a power source;
• an LED connected to the power source;
• a first switch connected in series with the LED;
• a second switch connected in parallel with the LED;
• a first regulation module including the first switch to regulate a power applied to the LED;
• a second regulation module including the second switch to regulate the power applied to the LED, wherein an operating period of the first regulation module and an operating period of the second regulation module do not overlapped with each other;
• a first check module to detect an energy value on a first node of the LED control system;
• a second check module to detect an energy value on a second node of the LED control system;
• and
• a control module connected to the first check module, the second check module, the first regulation module, and the second regulation module;
• wherein when the first check module detects that the energy value on the first node is greater than a first predefined value, the control module disables the first regulation module and enables the second regulation module, and when the second check module detects that the energy value on the second node is greater than a second predefined value, the control module disables the second regulation module and enables the first regulation module.
