The performance of led's has improved so much over time that these tiny bulbs aare all set to brighten our home, offices, buildings, light up streets, use in LED projector mobile phones, and they get involved in our lives in very interesting ways. Goverments are challenging companies to come up with viable, sustainable, LED-based home lighting solution not only for saving energy also to increase our lighting standards. LED- based home lighting solutions are cheap enough to replace a 60W incandescent lamp. Eco-friendly, low power led lamps might be the biggest step we take towards saving this planet.
Engineers involved in designing innovative and affordable LED lighting solutions can now benefit from a board product portfolio of LED drivers AC/DC power management devices, wired and wireless control and embedded processors. These products have an options to controlling power stages of LED lighting but also need to control LED currents. These eliminating the need of multiple components and reducing system cost.
The reliability of LED drivers is a crucial factor to achieve longer life expectations. While designing an LED driver, we need to taken care of component selection. LED lighting systems can be designed to accurately control voltage and current regulations for precise LED light intensity and colour mixing, temperature monitoring to prevent thermal runaway, intelligent and adaptive dimming of the LED and fault detection on over voltage or current, blown string. Communications with external systems are also possible via power line communication (PLC), wireless technology or interfaces.
