Shamsundar Shet - Field Application EngineerMr. Shamsundar Shet has over 9 years experience in electronics industry holding various positions, such as production engineer, R&D hardware engineer and field application engineer. Prior to joining National Semiconductor, Mr. Shet worked for Arrow Electronics as field application engineer. Mr. Shet holds a bachelor degree in Electrical and Electronics Engineering from Bangalore University.
Overview
Dimming of LEDs can extend the lifetime even further and also reduces power drain. Today's TRIAC phase-control wall dimmers are designed to interface with pure resistive load, such as incandescent or halogen light bulbs. Since an LED bulb does not appear as a resistive load to the TRIAC wall dimmer, dimming an LED bulb using a conventional TRIAC wall dimmer does not yield good dimming performance. In this Webinar, we will discuss in detail the challenges of LED dimming with a conventional triac wall dimmer and how National's new triac dimmable offline LED driver overcomes the issues and achieves full 100:1 range of uniform, flicker-free dimming. This solution enables truly direct LED light bulb replacement of existing incandescent or halogen bulb systems connected to standard TRIAC wall dimmers.
Company Introduction
National Semiconductor creates energy-efficient analog and mixed-signal semiconductors. Its PowerWise® products enable systems that consume less power, extend battery life, and generate less heat. Headquartered in Santa Clara, Calif., National reported sales of $1.89 billion for fiscal 2008 which ended May 25, 2008. Additional company and product information is available at www.national.com
