Dear Dr. Efficiency,
I’ve read in the news that governments worldwide are now promoting the use of power-efficient lighting through campaigns and initiatives. It seems that power-saving lamps will have a prosperous market. Are there any solutions from Fairchild specifically for this application? - Question Boy
Hello Question Boy,
One of the most popular power-saving lamps is the Compact Fluorescent Lamp (CFL), and they do have a very good market outlook. They offer significant advantages in energy-saving and consume up to 80% less power than traditional incandescent lamps. Thus, they have become popular in domestic and commercial lighting markets. In addition, governments worldwide are banning incandescent lamps and promoting CFL aggressively. It is expected that by 2012, the annual sales of CFL products will go beyond 5 billion units.
There are several products on the market today that provide proven solutions for LED, CFL, LFL and HID lighting applications. For CFLs, a dedicated control IC which works with external MOSFETs can be used for CFL ballast systems; or an integrated device with one control chip and two MOSFETs can be used. Fairchild offers several highly integrated devices that provides designers with less external component, reducing the overall component count, and smaller size, which is vital for space-tight CFL ballast designs.
Check out the datasheet for the FAN7711and FAN7710V to see if these are right for your design. These devices feature preheating and start up time adjustment through a preheating time set capacitor (CPH) which prolongs the lamp life; ZVS mode operation after start-up; and ‘open-lamp’ state detection without external components to implement protection and other functions.
Depending on your design requirements, you may be interested in a PFC control IC. These devices are ballast-control integrated circuits (IC) and allow the designer to choose the optimum dead time to reduce the power loss on internal switching devices (MOSFETs). Here’s more information on energy-efficient ICs for lighting.
If you are interested, we could meet to discuss.
