Communication and Networking Protocols

Adding intelligence to lighting applications includes creating lighting networks that can communicate locally and to remote locations. Adding communication capability to a lighting application improves the product's aesthetics, increases energy savings, reduces maintenance for fixed-light output and color in large lighting arrays (e.g. street lamps, large rooms, etc.), enables the monitoring of light output and resolves real-time operating issues. It also enables lighting to be integrated into other technologies such as security or home automation systems. It can be used to create custom mood lighting by varying the brightness, color and color temperature. 

Our solutions will help you enable these and other capabilities in your intelligent lighting design. You can create custom topologies that support multiple wired and wireless communication protocols to meet the requirements of your specific application and installation environment.

Lighting Communication Protocols

Demand for next-generation lighting communications is growing. Lighting designers are looking to take advantage of common communication standards, such as Power Line Carrier (PLC), RF, LIN, CAN, and Ethernet. With their large existing infrastructure, these protocols are electrically robust and provide relatively inexpensive cabling and installation. Our solutions provide the versatility to support legacy as well as emerging lighting protocols:

Wired Protocols

  • DALI
  • DMX512
  • 0–10V
  • PLC
  • LIN
  • CAN
  • RS232/RS485
  • USB (low speed/full speed)
  • Ethernet

Wireless Transceivers and Modules

  • Wi-Fi® 802.11 modules
  • Zigbee®, RF4CE, MiWi protocol 802.15.4 modules
  • Stacks for PIC® microcontrollers (MCUs)
  • Infrared/IrDA®

DALI Code Library

Beta code library available now

Digital Addressable Lighting Interface (DALI) is a standard lighting control protocol for large networked lighting systems. DALI provides bi-directional communications with uniquely addressed light sources. This allows for customized lighting schemes and the ability for the light source to relay information back to the controller (ie. light output level, color, energy usage, etc.).

  • 'C' based firmware library
  • Control Device (master) and Control Gear (slave) libraries
  • Automated commissioning
  • Firmware implementation on any 8-bit PIC® microcontroller
    • PIC microcontroller requirements
