LED Controllers

Ricoh offers power management ICs for LED lighting in 'Smart Society' that help our customers to add a new value to their products.

Constant Current LED Driver Controllers

We provide a constant current LED driver controller that can achieve human-friendly LED lightings. This controller can be used for LED lightings for FA equipment or various facilities that are directly driven by DC current. It also can be used for illumination for brightening surroundings or illumination for amusement that requires a large current or a wide dimming range. Also, it can be used for illumination for image recognition system that requires flicker-free lighting at photographing. This controller also can be used as a constant current controller for various equipments that require constant current.
