HB-LEDs feature huge longevity, low maintenance requirement, small size, design flexibility, decorative effect capability, safe low DC voltage operation, excellent cold weather performance, lack of mercury, superior color gamut and brightness are making LEDs extremely popular. IR offers dedicated control ICs which can use at best all the LEDs features either in a DC-DC environment or directly off-line. Furthermore IR ICs offers a high degree of integration, minimizing the design time needed and increasing system reliability.
