LED lighting control with powerline comms

Posted: 09 May 2011 ?? ?Print Version ?Bookmark and Share

Keywords:color tenability? powerline communication?

LED lighting continues to successfully carve out a growing portion of the lighting market, which is not surprising given that LEDs provide the best energy efficiency when compared to CFL and incandescent bulbs. However, LED fixtures are expensive to manufacture because of the high cost of LEDs and heat-sink design. Instead of competing with the CFL bulbs only on energy saving, LED Lighting manufacturers are trying to differentiate LED products by offering more advanced features than their CFL competitors.

For instance, LED fixtures can easily provide color tenability; i.e. the same bulb can give warm white light or cool white light, or any color in the spectrum. CFLs cannot do that today. LED fixtures can also be more intelligent through communication capabilities, enabling them to perform better control, diagnostics, and automation of functions. Given that all lighting fixtures connect to a powerline to convert electricity to light, many manufacturers are turning to the powerline communication interface to serve as the primary communication and control link.
