Current Limiting Diodes (CLD), also known as Constant Current Regulators (CCR), can be used to drive LED strips used in modern lighting systems. They can be easily switched in parallel in order to achieve any driving current required for the used LED type. Their disadvantage is temperature dependency of regulation current, as well as inability to provide a dimming functionality. There is a wide variety of LED driving ICs available, using pulse width modulation (PWM) for dimming LED lamps. Switching frequency is high enough to avoid any flickering of the lamps. Dimming level is either taken from the traditional phase-angle-controlled mains, or from analogue/digital signals provided from smart home systems.
