Abstract
In recent years, LED technology emerged as a prime candidate for the future illumination light source, due to high energy efficiency and long life time. Moreover, LEDs offer a superior flexibility to designers in terms of achievable colors and shapes. In addition, LEDs can illuminate and simultaneously transmit information embedded in their light output. Since there are many LEDs in a typical installation, two kinds of message collisions can cause time delays in data exchange, namely collisions among data messages and collisions between data and switching caused by typical LED driver electronics. Based on the two cases, we calculate the average delay time. A suitable partitioning of the message into data packets is proposed for PWM LED drivers with known and sufficiently stable clock frequency.
