DALI based light and motor control system for movable spot luminaires

With the development of automated lighting systems, accent lighting is undergoing a major transformation with the adoption of LED light sources. Movable spot luminaires are generally used for their beam effect and the ability to project texture. Spot luminaire units are controlled in many ways. This paper focuses on using DALI (Digital Addressable Lighting Interface) for controlling light and motors used in movable spot luminaires. In view of this, DALI protocol for both light and motor control is implemented on DLMC (DALI light and motor controller) which has STM32F302 MCU and the relative system includes DALI standard master unit, a slave unit, and the dual master - slave controller (DLMC).
