It is worth mentioning that in LED lighting design, the AC-DC power conversion and constant current drive circuits can adopt different configurations: 1) integrated configuration, which means the two are integrated and located inside the lighting fixtures. The advantages of this configuration include optimizing energy efficiency and simplifying installation; 2) Distributed configuration, where the two exist separately, simplifies security considerations and increases flexibility.
LED drivers can operate with constant voltage (CV) output according to different application requirements, that is, output voltage clamped within a certain current range; Constant current (CC) output can also be used for operation, and the output design can strictly limit the current; It is also possible to use constant current constant voltage (CCCV) output operation, which provides constant output power, so the forward voltage of the LED as the load determines its current.
Overall, LED lighting design needs to consider the following factors:
Output power: involves LED forward voltage range, current, and LED arrangement, etc;
Power supply: AC-DC power supply, DC-DC power supply, directly driven by AC power supply;
Functional requirements: dimming requirements, dimming methods (analog, digital or multi-level), lighting control;
Other requirements: energy efficiency, power factor, size, cost, fault handling (protection characteristics), standards to be followed, and reliability;
More considerations include mechanical connections, installation, maintenance/replacement, life cycle, logistics, etc.
