Lighting & Control Systems for the Smart Home

Expandable Multi-Board, Lighting & Control System

Multi-Board System Control Center Achitecture:

Designed to accommodate residential, and small to medium commercial applications. The multi-board Lighting & Control System employs an expandable approach that accommodates up to 1,280 LED light fixtures, 336 wall switches, 16 motion detectors and 14 daylight harvesting sensors distributed throughout the subject building. Light fixtures, switches, motion sensors and daylight harvesting sensors connect using Cat5/6 cable into a cluster of LED Driver Boards, Switch Reader Boards, Motion Reader Boards and Daylight Harvesting Board. These circuit boards are all housed in a Control Center along with the PMMI Lighting Controller and PMMI Lighting HUB.

  • PMMI Lighting HUB (Raspberry Pi)
  • PMMI Lighting Controller (Arduino Mega)
  • LED Driver Board(s) PWM (Pulse Width Modulation)
    • PMMI Lighting LED Light Fixtures (multiple styles)

Single-Board, Lighting & Control System

Single-Board System Control Center Architecture:

Designed to accommodate new builds of small residential (cottages, tiny-homes, RVs, mobile homes) applications. The single-board Lighting & Control System accommodates up to 96 LED fixtures, 14 wall functions, and 2 motion sensors. The Single Board Controller, as well as The PMMI Lighting HUB are all housed in the Control Center. PMMI Lighting’s LED, Low voltage, Light Fixtures and Wall Switches connect into the Control Center through a series of daisy-chained, Cat5/6 cables, therefore providing both power and control. Likewise, motion detectors connect using Cat5/6 cable for both power and control.

  • PMMI Lighting HUB (Raspberry Pi)
  • Single-Board Controller (Arduino Mega & Driver Board, Switch Board & Motion Board combined)
    • PMMI Lighting LED Light Fixtures (multiple styles)
    • PMMI Lighting LED Bulbs (use conventional lighting fixtures with PMMI Lighting bulbs and adapter kits)
    • Fixture Cans (if using insulation)
    • 1, 2, 3, 4, and 6 Button Switches
    •  Motion Sensors
  • Cat5, Cat5e or Cat6 Low Voltage Cabling (customer supplied)
  • Internet Connectivity(customer supplied)
  • Power Supply (customer supplied)

Cat5/6 Cabling

Lighting & Control Systems use Cat5, Cat5e or Cat6 cable with RJ45 connectors for power and control. All PMMI Lighting’s LED Light Fixtures and wall switches connect to the control panel through a series of daisy chained Cat5/6 cables. Likewise, motion detectors connect using Cat5/6 cable for both power and control. Cat5/6 jumper cables are used for inter-board communications. The use of low-voltage cable eliminates the need for conduit hence allowing another significant cost reduction.

Internet Connectivity

The PMMI Lighting HUB provides internet connectivity to the lighting system through Ethernet. PMMI support uses internet for timed events, installation, diagnostics, configuration, and software updates.

Power Supply

12V DC

PMMI Lighting Circuit boards, the PMMI Lighting Controller, the PMMI Lighting HUB, and motion detectors are powered using 12V DC.

How many fixtures can be daisy chained?

The different DC voltages determine the number of LED light fixtures that can be daisy chained on a single Cat5, Cat5e or Cat6 cable. PMMI Lighting LED Light Fixtures are powered with either 12V, 24V, 36V or 48V DC.

PMMI Lighting has a several different fixtures with different specifications. For this example we will use the 6 watt LED Recessed Downlight in the Multi-Board, Lighting & Control System which has 16 channels per board (max 10 boards per system).

  • A 12V power supply supports one downlight per channel = 16 lights per driver board
  • A 24V power supply supports three downlights daisy chained per channel = 48 lights per driver board
  • A 36V power supply supports four downlights daisy chained per channel = 64 lights per driver board
  • A 48V power supply supports eight downlights daisy chained per channel = 128 lights per driver board

PMMI Lighting has a several different fixtures with different specifications. For this example we will use the 6 watt LED Recessed Downlight in the Single-Board, Lighting & Control System which has 12 channels.

  • A 12V power supply supports one downlight per channel = 12 lights
  • A 24V power supply supports three downlights daisy chained per channel = 36 lights
  • A 36V power supply supports four downlights daisy chained per channel = 48 lights
  • A 48V power supply supports eight downlights daisy chained per channel = 96

Power

AC/DC power supplies are readily available which accommodate standard 120V AC and 240 V AC line voltage. These power supplies are used as stand alone, or in combination with battery packs that provide backup power in the event of a grid power failure. The system works well for off-grid applications with battery backed solar or wind power.

PMMI Lighting support can help size and select power equipment for just about any application.
