10. How compact fluorescent lamps work - and how to dim them
Compact fluorescent lamps (CFLs) are replacing incandescent light bulbs at a rapid rate due to their tremendous energy savings and longer lifetime. Additional energy savings can be achieved by dimming, but the electronic ballast required to control the lamp has a higher cost and is difficult to design. This article written by Tom Ribarich of International Rectifier explained how a CFL works, how to dim them, and describes a solution for 3-way dimming applications.
Steve Elliott of XP Power examined the issues surrounding why you should try to avoid using a fan to cool a power supply.
Lighting comprises approximately 17.5% of global electricity consumption. As the world transitions from incandescent to solid state lighting (SSL) technology, utilities and government regulatory agencies worldwide are concerned that, as this large segment of the consumption base switches to SSL, it will increase infrastructure costs. This is due to the reactive nature of LED-based solid state lighting, which results in higher distribution currents that adversely affect power factor (PF) and, in turn create a larger demand on the power grid explained Hubie Notohamiprodjo of iWatt,
