Overview
Lighting management control can minimize peak energy costs and consumption by providing the right light levels at the right time. Typically 30%-50% savings in energy
consumption can be saved by a lighting management system that can employ aggressive control strategies.
Standards bodies are proposing tougher energy standards that are transitioning from voluntary to mandatory; for example; USGBC LEED (Leadership in Energy and
Environmental Design), the ICC (International Construction Code), Title 24 in California, and ASHRAE 2010. Taking advantage of these guidelines can be complicated and
require an automation control system to make implementation easy. Compliance to the standards may need to be veried by real time metering and monitoring of energy
performance to verify building code or standards compliance.
For existing facilities, retrotting existing electrical systems with wired lighting control systems can be complex and expensive. The need to reduce material and labor upgrade
costs has put a focus on wireless lighting control technologies. Wireless solutions can provide an effective way of retrotting lighting controls without the expense of modifying
existing wiring.
Wireless control can provide exibility. Should the space usage change, lighting zones can be established regardless of existing circuiting. Controlled zones and system
behavior can be easily modied in software.
Wireless controls cost make sense as an value added cost to LED lighting technology. The rapid market acceptance of solid state lighting has driven down the cost of
dimming control. When coupled with the emergence of low cost radio frequency (RF) technology, wireless control system costs support 3-5 year pay backs.
Control Strategies
The LumaWatt System automates combinations of the four basic control strategies resulting in signicant savings.
Scheduled ON/OFF
The basic automated event is a scheduled on or off by time of day. The LumaWatt System can use astronomical clock or photo sensing to create dusk-to-dawn,
dusk-to-curfew, e.g., business closing, or any time scheduled period of operation.
Scheduled Dimming
As an alternative to simple on or off, a dimmed lighting level may be scheduled for a period when security is required for periods of low usage, e.g., full brightness
from dusk-to-business closing then dim 50% to lower security level lighting until dawn.
Occupancy Detection
Energy is saved by reducing or extinguishing lighting when the site is no longer in use. Motion sensing can ensure that light is available when an area is occupied
then reduced upon vacancy. The LumaWatt System can time schedule periods where occupancy detection triggers an appropriate level of lighting. Use of daylight
harvesting.
Daylight Harvesting / Lumen Harvesting
Photo sensing can adjust or “hold off” luminaire light output and take advantage of “daylight harvesting” opportunities, e.g., parking garages with open sides.
During commissioning the lighting system can be calibrated to maintain target lighting levels, adjusting for luminaire lumen depreciation saving additional energy.
Key Features
The LumaWatt Outdoor Wireless Control System provides a exible and reliable wireless solution that addresses the market needs.
• Factory installed luminaire sensor guarantees luminaire capatibility and performance.
• System operation is monitored and reported in real time for verication of occupancy, power, daylight harvesting and light level.
• Power monitoring is measured in real time to 2% accuracy.
• Failure detection and notication helps maintain quality of service.
• Device level self-diagnostics assists in network troubleshooting.
