Development and research of lighting system based on DALI

The design scheme and related implement of a DALI (digital addressable lighting interface) lighting system which is more practical and efficient are described. With a view to the shortcoming of current application of DALI solutions, this paper discusses the design procedure which realizes the DALI communication based on ATMEGA8L and sets the lamps addresses from user setting in the slave unit itself, and takes advantages of the three-state mechanism of system, which consists of controller unit state, implementation state and target object state. Finally, three different sensor network solutions based on DALI system are proposed and compared in this paper.
