ProLight III

ProLight II Low Voltage Light System

ProLight III Controller

Max 1 per ProLight III • located in The Control Center

The Arduino Mega Controller, is the “brains” of the system and provides real-time monitoring of switches, motion sensors, timed events, and subsequent control of the lighting system. The Controller is completely dedicated to real-time functions in order to ensure high reliability, responsive, and smooth (no flicker) lighting-control performance.

The Arduino Mega is single-board controller available from Arduino and many third-party suppliers. Millions are in service in professional and do-it-yourself applications across the globe. The Arduino is a premier platform, used in electronics and computer engineering education programs worldwide. Click here for more information on the Arduino Mega.

The Raspberry Pi is a single-board computer running the Raspbean Linux operating system. The Raspberry Pi provides:

  • Internet Connectivity (WiFi and Ethernet)
  • Graphical User Interface for PMMI support
  • Real-time server for Arduino controller (e.g. time and configuration updates, remote control)
  • Installation-specific configuration hosting

The Raspberry Pi is an open-source computing platform available from multiple vendors and broadly used worldwide by product manufacturers, educators, and do-it-yourselfers. Click here for more information on the Raspberry Pi.

Components that make up the ProLight III Controller are: a Controller Mother Board, Arduino Mega, a Raspberry Pi, a Memory Daughter Board, a Regulator Daughter Board, and a Level Shift Daughter Board. The daughter boards, Arduino and Raspberry Pi are plug-in replaceable on the mother board.


ProLight III Driver Board

Max 10 per ProLight III • located in The Control Center

PMMI Lighting light fixtures are driverless, they do not have on-board drivers, instead, drivers are hosted on Driver Boards. Separating the driver from the fixture allows the electronics to operate at lower temperatures thus extending life expectancy. Eliminating the driver from the fixture also reduces fixture cost.

Each Driver Board can accommodate up to 16 LED light strings or “channels”, each comprised of up to 8 – 6 watt fixtures connected in a daisy chain manner using 18 awg, 2 conductor zip chord.

Each channel has a constant-current driver. Driver output current, and thus luminaire intensity, is controlled through a PWM input signal delivered by an on-board 12-bit PWM controller providing high-fidelity lighting control.

PWM control is regulated between zero and 100 percent. This results in constant current output from zero to the driver’s rated current. In this example, 1 Amp (1000ma) drivers are used. In the event that the physical area illuminated by the channel is too bright, it’s possible to lower the maximum intensity by swapping out the driver module for 300, 500, 700, and 1000ma drivers. It is also possible to set the max light percentage output by specifying it in the configuration software under the channel tab without changing out the drivers.

Components that make up the ProLight III Driver Board are: a Driver Mother Board, a PWM Daughter Board, and two Driver Daughter Boards. Daughter boards are plug-in replaceable on the mother board.
