Llighting control for a broad set of  applications is an ideal application for the Unison or DSPnano operating system.  This applies to a broad set of light sources as well including: 

• LED lighting
• Florescent
• Incandesant
• Halogen

The most interesting of these choices is LED lighting because of the subtantial savings in energy that are created.  Often these new lighting systems are integrated with a variety of networking software including: 

• IPV6 and 6loWPAN
• Zigbee
• 802.15.4 low cost alternatives

By integrating low power wireless systems into a lighting system there is a number of benefits.  For example, light switches become movable to any location.  Fewer wires are required and installation costs are much lower.  A variety of protocols can be used for lighting control of this type.

Using PWM and a small collection of analog components a broad set of light types may be lit.  LED lighting control is a good example.  By using three different light sources and three PWM outputs and ideal color balance may be achieved.  The LED lighting circuits for these three different colors are really just constant voltage output devices with precision voltage control (for patent reasons).
