Visible light communication (VLC) is a wireless method that uses light emitted by LEDs to deliver networked, mobile, high-speed communication similar to Wi-Fi, leading to the term Li-Fi. It can be used as standalone solution or in a supplementary role to radio-frequency (RF) or cellular network communication. The basis of the technology, conceived by Professor […]
With efficacy and service life steadily increasing and costs declining by about 18 percent each year (Memoori, 2014), the LED revolution continues to develop at a rapid pace. LED’s inherent compatibility with digital control, aided by other trends, is setting the stage for the next LED revolution: smart lighting control. Many LED products are sold […]
Radio-frequency (RF) wireless lighting controls are control devices such as manual switches, occupancy sensors and photosensors that communicate via radio waves. Eliminating control wiring may reduce total installed cost while facilitating application of automatic lighting controls in existing construction where installing new wiring would be costly or problematic. As investment has favored existing over new […]
ELECTRICAL CONTRACTOR recently published a feature article about wireless radio-frequency (RF) lighting control written by Craig DiLouie, LC. “This approach promises a number of benefits compared with hardwired solutions. First is flexibility; devices can be placed where needed, installed faster and moved more easily. Electrical planning may be shortened, and irregular applications can be better […]
Intelligent, controllable LED lamps offer a new paradigm for home lighting control. Julie Jacobson, editor of ELECTRONIC HOUSE, analyzes the pros and cons of 13 products implementing WiFi/Internet of Things, 6LoWPAN, ZigBee, Z-Wave and Bluetooth. Read it here.
New research by Navigant suggests wireless technology is entering the mainstream of the commercial buildings controls market. While building automation and controls have been used for decades, wireless networks are enabling more granular control over building systems without many of the design and labor challenges involved with running traditional cabling to support communications and/or power. […]
Craig DiLouie, LC recently interviewed Mike Crane, product manager for Hubbell Building Automation, for ELECTRICAL CONTRACTOR on the topic of wireless RF lighting control. The interview is published here in its raw form. DiLouie Please describe what wireless RF lighting control is, how it works, and its intended purpose. Crane: Wireless RF lighting control is […]
EC&M has published an article about trends in lighting control, noting occupancy-based shutoff and daylight harvesting and then focusing on LED control, including wireless options. Read it here.
The International Electrotechnical Commission (IEC) has ratified a new standard–ISO/IEC 14543-3-10–for wireless applications with ultra-low power consumption pioneered by EnOcean. The standard can be downloaded from www.iso.org. The new standard is geared to wireless sensors and wireless sensor networks with ultra-low power consumption. It also includes sensor networks that utilize energy harvesting technology to draw […]
Stairwells account for about 2% of multistory commercial building floorspace, with an average of one light fixture for each 58 sq.ft. of stairwell, according to the International Facility Management Association. It is trafficked 3-5% of the average day. This application has emerged as a strong potential opportunity for energy-saving controls. In the near future, in […]
