Wattstopper Digital Dimming Room Controller

LMRC-220 Series Digital Room Controllers include one or two output(s) to control a total of up to 20 amps. Load ratings include incandescent, magnetic low voltage, forward phase compatible electronic low voltage and LED drivers, neon and cold cathode, and dimmable two-wire and threewire fluorescent ballasts. They are the foundation of a WattStopper Digital Lighting Management (DLM) system, and allow integration of occupancy sensors, daylighting controls and switches for energy-efficient lighting control.

Key Features

• Versatile 20A controllers with line voltage relay(s) and triac-based forward phase control dimming
• Compatible with most load types; three selectable dimming curves for each load
• Plug to other components using Cat 5e cables with RJ45 connectors eliminating wiring errors
• Plug n’ Go automatic configuration for quick startup
• Store load preset level and 16 scene preset levels for each load

Solutions for Load SheddingWith energy alerts on the rise and demand charges increasing, load shedding has become an important lighting control strategy. Because many lighting loads are non-critical, they are prime candidates for load shedding along with other non-critical building loads.

Daylighting Controls
Load shedding with daylighting controls is a natural, automatic process. Because high energy demand often occurs at the same time daylighting potential is the greatest, the natural consequence of using daylighting controls will be to reduce lighting as the level of daylight increases and becomes adequate to replace artificial lighting sources.

With continuous dimming products, such as The Watt Stopper’’s LightSaver LCD control, users can define the minimum light level they want to maintain throughout the course of a day, and the dim- ming controls will adjust artificial lighting based on this setpoint and the available daylight contribu- tion. When daylight is adequate, lights will be dimmed and when daylight diminishes, artificial light levels are raised. The multi-zone option of the LCD enables the use of independent dimming controls in different areas of a building space, such as an open office area, where daylight levels may differ. One lighting zone, nearer to windows or skylights where daylight levels are higher, may dim artificial light- ing earlier in the day and to lower levels than in another lighting zone that is located further from the daylight source and receiving a smaller daylight contribution.

ON/OFF switching controls, such as The Watt Stopper’’s LightSaver LCO control, are also effective load shedding tools. Compatible with all lamp types, ON/OFF controls turn lights off when the daylight contribution reaches a user-defined level. Multi-zone controls enable bi-level, or stepped dimming, which can be particularly effective as a load shedding strategy. Most commonly, individual lamps with- in a multi-lamp fixture will be grouped into different zones; the inner lamps in three-lamp fixtures in one zone and the outer two lamps in a separate zone. The lighting in each zone is turned off once day- light levels reach a defined setpoint. Usually, the zone comprised of the inner lamps will be turned off first, reducing lighting by one-third. Later in the day, when the daylight contribution increases, the other lighting zone can be turned off. For more aggressive load shedding, the sequence can be reversed, to shed two-thirds of the lighting load earlier in the day.
The Watt Stopper Application Bulletin
Lighting Control Panels
Another effective tool for achieving load shedding is the use of lighting control panels. Panel prod- ucts perform load shedding by turning off non-critical loads during peak times.

For instance, users of The Watt StopperComplete Control panel products can employ a prepro- grammed control scenario to shed non-critical lighting loads. This could be half of the lighting in a "bi-level" controlled space. Under such a scenario, occupants are "locked out" from exercising local overrides via switches or telephone contact with the system. This control scenario can be pro- grammed to operate during daily intervals when peak loads are most likely to occur, or when a facility historically attains its highest demand. This strategy can also be invoked under energy shortage alerts.

Specialized Load Shedding Solutions
Additional automated load shedding solutions include teaming The Watt Stopper Automatic Relay Pack (ARP) with the Telephone Switch Module (TSM). Non-critical, sheddable loads are connected to one relay on the ARP-Net, while critical, non-sheddable loads are connected to the other relay. The TSM is installed on the ARP-Net network. During a power alert, a call into the TSM from the facility manager will turn off the relay with non-critical loads. The ARP’s lock-off capability ensures that once the signal from the TSM is received, lighting or other loads (i.e., HVAC, fans, etc.) immediately shut off, and that ordinary occupant overrides are not available. To restore the loads, the facility manager makes only a quick call back to the TSM and follows a sim-
ple push-button sequence.

LED Emergency Sconce

For the electrical engineering community here in Nashville and middle Tennessee, this is a great emergency LED sconce.  I have ordered a sample for TLC Engineers who asked to see the fixture and can bring it for a demonstration to anyone else who would like to see it...  thank you.

Revision June 6, 2011

Final version June 30, 2011 2 Design Calculations with Solid State Lighting

Abstract
For decades, lighting calculations have been the backbone of lighting designs for almost all lighting applications, indoors and out. Good practice in illuminating engineering dictates that the designer uses photometric data that is adjusted to meet the conditions of the intended application by accounting for temperature, dirt, and variations of components. With LED lighting systems, the photometric test method ("absolute photometry") differs from conventional source lighting ("relative photometry"). In order to properly predict the performance of an LED lighting system and to compare results to competing conventional lighting systems, designers must be particularly careful to use appropriate factors in addition to properly using the two different photometric data formats. A discussion of each of the factors and examples of comparative calculations are provided.

Lumewave, Wireless Lighting Control

Wireless Street Lighting Controls

Lumewave's wireless, remote control and monitoring of street lights can save energy, enhance public safety, reduce light pollution, reduce maintenance costs, provide valuable M&V information, and fixture health reporting to municipalities, states and other users. They can be used with LED, Induction, Plasma, eHID lighting, and standard HID. However, because of certain limitations with older HID technology, Lumewave can still be used with those systems, but much functionality is lost.

A centralized command system can send astronomic time based instructions to individual or groups of street lighting to reduce energy consumption, when and where possible, during night time hours.

Demand responsive and adaptive, lighting can be dropped to lower levels through user selected, multi-level dimming scenarios, or based on input from traffic monitors or other systems and sensors.  Revenue grade power metering through the use of Smart Meter chips is standard.

Signaling for location identification of Call Button activation or 911 calls, designating evacuation routes, detours and other emergency uses are standard capabilities with Lumewave controls.

Additional public safety uses can include the ability for police or other emergency vehicles to interface through their onboard computers and raise light levels from nearby streetlights even higher than normal to aid in visibility for investigation, medical administration and incident clean up.
Lumewave's Gateway and software allow users to communicate with over a million system devices if a customer's network was that large. Standard units provide a 5 mile range to devices when mounted on poles twenty feet or higher.
