LumenCache adds intelligence to the last 1000 ft of power distribution.
Renewable energy sources and LED lighting have changed the requirements for local power distribution in homes and buildings.
The LumenCache platform replaces traditional 110V AC power distribution in buildings with a new standard more appropriate to the low power needs and digital capabilities of electronic devices including LED lights.
Highly Modular MicroGrid Platform (How it works)
BASICS: LED luminaries (light chips) require constant current power to operate without damaging the diodes (the”D” in LED). This driver can be located at a distance from the light fixture so LumenCache places them in centralized and easily accessible lighting panels. Standard Cat5 or Cat6 wire is used to send LED power from the driver to the LED Array(typically 1 LED but can be a string of up to 20 until the maximum voltage drop is reached). Other configurations are also possible for high power or color-changing LED lights, motorized shades, and fans.Thanks to the extremely low power requirements of LEDs, only 2 pairs of wires in the Cat5 are needed for LED power. With the extra wires in the Cat5, LumenCache provides command/control data communications and regulated power to devices attached along the Cat5 wires. This includes sensors, keypads, indicators, switches, and more. Each Cat5 from the panel includes Data, Sensor/Keypad Power, and either LED Power from a Driver or Fused Power from the large DC power source. Smart Interface Blocks (SIBs) simply fixture installation.All electronic components use DC power internally so LumenCache typically includes one large AC/DC power converter that also charges a battery. Thanks to the battery buffer, interruptions in the AC power supply from the utility grid do not affect the operation of the system, until the battery level drops below a preset point. This also protects the system from sags, surges and variations in the grid-delivered power.WIRING: The Power Distribution Module connects the field Cat5 wiring from the Field Devices (Lights, Switches, Keypads, Sensors, etc) back to 16 Ports. Ports are RJ45 jacks and the Cat5 is typically wired in the standard TIA-568B configuration (While/Orange, pin 1). Field Devices may have an RJ45 tip or a convenient tool-less connector. A Wire Adapter can attach Port Cat5 wires to other wire types.
Depending on the type of field devices connected to the Port, specific Pucks are connected to the matching 16 Puck Ports. For example, if a switch is connected to the wire connected to Port 1, then a Switch Puck would be inserted in the Puck Port 1 14 pin connector. A Switch Puck reads the switch in field, and produces an ON/OFF or dimming Channel Signal. There are 16 Channels on each PDM that are shared at each Puck Port. A jumper selector chooses which Channel the Puck Port is transmitting or receiving on.
A Driver Puckwill produce regulated power to the attached LED Array in the field. Driver Pucks listen to their selected Channel signal (i.e. from a Switch Puck) as selected by the jumper, and turn ON/OFF or dim their attached LED.Up to 48 Driver Pucks can listen to the same Channel and be commanded by a single Switch Puck. The 16 Channels are extended to the PDM Expansion Bus at the top and bottom of each PDM. Connecting the PDM Expansion Bus cable will allow additional PDM Ports to listen to the same 16 Channels. At any point, the Expansion Bus may be split, by omitting the expansion cable, and a new 16 Channels are available starting with the next PDM.The LC-Bus allows communication between Smart Pucks and any top level control interfaces connected via the Comm Bus ports. All LC-Bus devices should be connected to allow communication between each other. This includes PDMs, Power Management Modules, and Main Brain modules. Mini Brain modules connect to PDM and PMM ports.ID CONFIGURATION: Each LC-Bus supports up to 65,000 Device IDs. Assign IDs to each Smart Device such as Switch Pucks. When two or more Switch Pucks have the same ID, they will all act together as one. Brain interfaces can quickly assign IDs or use manual mode.
CONTROL: Brain Modules provide the automation and interface to other control systems. The Mini Brain provides RS232 and IP interfaces to the LC-Bus and is typically used to interface LumenCache to other control systems such as Savant, Crestron, Control4, HAI, RTI, AMX, in addition to Smart Meter HANs, and the included simple browser interface. ImPuck adds ElectricImp cloud access and IP connections.
A Main Brain Module allows the connection of more than one LC-Bus into a larger network via the Main Brain Ethernet port. This allows very large scale networks to be created with distributed automation and control processing to ensure sufficient communication speeds are maintained.
It is important to use the Behavior layers of the controls to optimize the system in large networks. This feature distributes the processing so the complete system is more fault-tolerant and “intelligent”.

Where can I use LumenCache Lighting? LumenCache Legacy line is ideal for residential new construction, offices, schools, restaurants, sports and theme bars, condos, townhomes, hospitals, elder-care facilities, remodels, barns, labs, machine shops, nurseries, luxury yachts, off-grid homes, bamboo huts, eco-tourism lodges, home theaters, swanky hipster clubs, … Oy! this is a long list. Anywhere you want to get lots of lights, be able to control and dim them perfectly, and benefit from having smart sensors to automate the lights and blinds. Is there any application where it’s NOT recommended? Yes. LumenCache separates the LED driver from the luminary so it needs to send DC from the lighting panel to the light. For most lighting applications LumenCache can easily suport up to 1000′ from the closet to the lights. However, DC power does not like to go long distances at HIGH CURRENT, so huge lights that draw 48W placed at long distances from the PDMs are not practical for DC distribution applications. This includes high-bay lights in convention halls and street lights that are far apart. Residential floodlights are fine due to the relatively short cable runs. Lasts forever, inexpensive to install, safe, perfect control, super light output and color, battery backup…ok, how much does it cost? Total installed cost is typically within 10% of an old-style 110V AC dimmed LED lighting package like a Lutron or Control4 system. Remember, installation is typically less. When you get above 85 lights, it tends to cost LESS than AC LED systems. LumenCache is like nothing I’ve seen before. Is it Patented? oh yea. Two US Patents Pending covering everything from the modular design to the unique adaptive controls. I can get 110V AC LED bulbs everywhere. Where do I get LumenCache lights? All LED lights contain the compatible LED but it’s much easier to buy lights specifically made for LumenCache. These fixtures typically include the RJ45 connector or Smart SIB built-in. You can remotely connect an Adapter SIB to any Constant Current or Constant Voltage LED light that does not have an AC driver embedded in it. Dozens of fixture manufacturers are starting to make LumenCache compatible fixtures and LEDs.
