With the invention of Ultra-Bright LED, solid state lighting has come to something which is much
more efficient and energy saving when compared to conventional incandescent or fluorescent lighting. With
the use of proper driver electronics now a days it is possible to install solid state lighting systems with the cost
same as that of any other lighting technology. This paper is a part of the research project we are doing in our
lab, which deals with using ultra bright LEDs of different colors for lighting applications. The driver
electronics are made in such a way that, the color and brightness of the lights will change according to
context. For instance, if one of the users is reading a story or listening to music in a Personal Computer or in a
hand held device such as a PDA, the lighting systems and the HVAC (Heating Ventilation Air-conditioning)
systems will change dramatically according to the content of the story or the music. The vulnerability of
solid-state lighting helps to accomplish such an effect. Such a type of system will help the reader to feel the
story mentally and physically as well. We developed complete driver electronics for the system using multiple
microcomputers and a full software suite which uses complex algorithms to decode the context from text or
music and synchronize it to lighting and HVAC information. The paper also presents some case-study
statistics which shows the advantage of using the system to teach kindergarten children, deaf and dumb
children and for language learning classes.
