Most commercially available LED “light modules” are constructed by connecting a number of LEDs in series orinparallel to form cluster or string configurations. In cases where these lights modules include a constant-current driver as part of the assembly, an external “constant-voltage” driver or power supply is required.
Low cost LED circuits control the current flowing through the LED with a simple resistor. This is another case where a constant-voltage power source is required. Other examples where constant voltage supplies have been employed include ads signs, traffic information signs and large screen high definition LED displays.
Constant-voltage drivers come in many different forms. They can look like a conventional power supply or they can be enclosed for moisture and environmental protection.
