Voice Controlled Ambient Lighting with DALI

Renesas’ digital addressable lighting interface (DALI) system is widely used in commercial lighting control and building lighting control

Image of Renesas’ Winning Combination - Voice Controlled Ambient Lighting with DALIRenesas’ winning combination voice-controlled ambient lighting with DALI is a lighting control protocol for intelligent lighting systems. The DALI system is widely used in commercial lighting control and building lighting control. The DALI 2.0 standard improves the ability to control brightness, glare, color rendering, and presence detection, and adds multi-vendor interoperability to the DALI standard, IEC 62386. It also introduces the standardization of control devices, such as application controllers and input devices.

Renesas provides both DALI and DALI 2.0 control/communication software. In this reference design, Renesas features the RL78/G12, RL78/G13, RL78/I1A, and Synergy S128 Series microcontrollers (MCUs). In addition to highly integrated MCUs, the design also features an LED driver, power components, light sensors, and proximity sensors for DALI 2.0, as well as transceivers/receivers for the host computer interface.
