The Lighting Control Innovation Award was created in 2011 as part of the Illuminating Engineering Society’s Illumination Awards program, which recognizes professionalism, ingenuity and originality in lighting design. LCA is proud to sponsor the Lighting Control Innovation Award, which recognizes projects that exemplify the effective use of lighting controls in nonresidential applications. In the award’s second year (2012), 13 projects were recognized with an Award of Merit.
This month, we will explore the role that intelligent wireless lighting control plays in an extraordinary streetlighting scheme developed by Illuminating Concepts.
The project objective was to develop a secure web-based wireless outdoor area lighting control infrastructure completely integrated within specialized luminaires. A strict budgetary process was put in place at the beginning of the design.
Control aspects of lighting include full range dimming of LED light sources
0-100%, fail-safe on-board photosensor to bring light level up to full in the event of a control system failure, lumen maintenance and LED temperature monitoring with automatic adjustment.
Optical performance control with select luminaires? changing from type 5 to type 3 distribution with reduced lumen output.
The control system supports auxiliary lighting control of accessory fixtures mounted to the pole, such as panic buttons with 2-way communication.
Emergency management or crowd control capabilities are handled through the control of on-board 4 color indicator lights capable of flashing and sequential strobing combined with audio announcements in any language. With the addition of card-swipe or biometric sensors, the system supports on-street parking management, rental charges for EV charging applications and PDA downloads. Sensor technology accommodated within the pole interfaces with the control system to provide real-time monitoring of weather, CBRNE agents, seismic conditions and presence of water (flooding).
The control system allows content management for all video-based functions including roadway signage and parking system interfaces. This messaging may be displayed on both large format banner-type signage and street signs.
Control aspect of audio include content management, volume adjustment, zonal control of audio distribution on a pole by pole basis, automatic audio synchronization, error-checking and delay correction. The audio control system also includes the ability to make real-time announcements from authorized users.
Video camera control is provided for purposes of surveillance and footfall counting and utilizes edge processing technology and analytic algorithms. The control system manages image changes and distributes these changes to a centralized command center.
