Distributed Control

Each individual intelligent LED fixture is controlled by a Digital Light Agent – our patented combination of:

Wireless mesh networking based on the open ZigBee standard

Passive infrared occupancy sensing

Digital ambient light measurement

Power monitoring and energy metering

Real-time sensor logging

Programmable, rules-based control

With distributed control technology, the Intelligent Lighting System has the best of both worlds – split second-decision making at each LED lighting fixture and centralized control for configuration, management, and reporting. The Digital Lumens Agent takes input from multiple sensors – like occupancy and ambient light – and processes this according to the rules pushed to it by the LightRules management system.  In the blink of an eye, the intelligent fixture provides exactly the right amount of light for a person entering a room or a forklift rushing down an aisle.

Centralized Management

The LightRules Management System provides a simple yet powerful web-based user interface allowing facility managers to wirelessly configure, control, and optimize all aspects of their Intelligent Lighting System. It features:

FLEXIBLE LIGHTING CONTROL

Facility managers can define rule-based “profiles” to govern lighting behavior at any level of granularity – across an entire facility, zone-by-zone, all the way down to an individual fixture.

DETAILED REPORTING

Each intelligent fixture captures a detailed history of energy usage, occupancy, and ambient light. LightRules’ reporting functionality allows easy visualization of this data for utility M&V or corporate energy accounting.

DATA-DRIVEN OPTIMIZATION

What-if analysis tools use past data to predict future performance, quantifying how much energy can be saved with each change of a profile.

AUTOMATED COMMISSIONING

Streamlined commissioning tools reduce the complexity of configuring intelligent light fixtures, shortening the time required for initial setup.

OPEN DATA INTERCHANGE

Connect LightRules to any Building or Energy Management System which supports XML or JSON data interchange via its HTTP-based API.

LIGHTRULES MONITOR

LightRules Monitor is a remote optimization service that provides ongoing analysis of key lighting system metrics, and actionable recommendations about how to further optimize settings for greater efficiency.

 

Integrated Controls versus Ala Carte:

In “non-intelligent” LED’s .certain features can be added, an occupancy sensor can be added, a dimmer, daylight harvesting etc. The issue is that these features are Ala Carte and are added on and are not integrated. These controls are usually made by different manufacturers and are not warranted by the lamp manufacturer. In the case of failure, any of these individual devices will need to be retrieved and sent for repair or replacements separately and then the replacement reinstalled. In the case of the Digital Lumens in the instance of failure of any component (failure statistics in a later section) the entire fixture is retrieved and a new one installed.

With non-intelligent LED’s once the additional cost of these “devices” is incurred and installed on the fixtures they are rarely designed to work together. This problem is usually encountered “post installation”. In fact some devices preclude the use of other components on a fixture without dramatic additional cost and deign altering and warranty voiding, modifications. For example we have yet encounter an LED (other than DL) where daylight harvesting (critical in California) can work with dimmer or data mining equipment, In the

Digital Lumens system all of these components are standard and are engineered and designed to work in perfect harmony with each other assuring that the maximum possible savings is achieved.

 

Occupancy Sensors and Dimmers:

These controls while they should be standard are often overlooked. While occupancy sensors are standard on every Digital Lumens fixture this feature is not on every other LED. Let’s examine the perm aisles at Pittston. In most of the perm aisles there are 6 lights. The way that we have currently programmed them the lights at both ends of the aisles are set at 100% and. 50%, meaning that an employee can see very well aisle ends even at 50%, when they approach the light instantly goes to 100%. The 4 lights in the interior of the aisles are currently set a 70% when active and 10% when nobody is in the aisle. In essence when the aisle is unoccupied the lights are consuming the equivalent of a 27 watt bulb.

If we installed a non-intelligent alternative there would need to be separate occupancy sensors on each light as well as a dimmer to try to duplicate what has been done at Pittston. This is usually not the case as to conserve on costs many vendors will only put occupancy sensors on the lights at the ends of the aisles. This results in all lights in the aisle going on when the outer lights detect movement, wasting energy. Further most dimmers have setting in increments of 20% and must be adjusted manually.

In the case of both ala carte dimmers and occupancy sensors any changes would need to be made by sending maintenance personnel up in a lift to set the DIP switches on each fixture if changes need to be made. In most case the site would simply forego the improvement.

In the system installed at Pittston all of the characteristics describe above can be and havebeen adjusted instantly from the ground. In all aisles we have programmed the lights toemit only 70% of their full output when occupied (other LED’s cannot do this) and 10%when unoccupied as well as the time after the aisle has been vacated that the light dims (30,60, 120 seconds etc.).

There are times in a facilities life when the purpose of an area may change. For the illustrations sake let’s assume the customer wants to put a hand pick area into what is currently bulk. We further assume that this area will be serviced by 16 lights. The currentsettings in bulk may not work well in a “hand pick” area. These 16 lights can be separatedinto a new zone wirelessly and given characteristics suitable for hand pick activities. This can be done in matter of moments via an intelligent lighting system sparing the site theexpense of changing lighting.

It is this control that made possible the increased incentives previously mentioned as well as the enhanced ongoing energy savings to customers.
