Intelligent lighting has evolved over the years. Initially, they were used for non-stationary illumination and stage lighting applications.
The technology is promising two-way remote communication and control of up to 500 devices in the home
Later, the desire for sustainability in energy consumption has led to the usage of sensory input from the environment to wirelessly control the brightening, dimming and switching on and off functions.
Intelligent lighting has moved on to “smarter city” concepts and for building automation. Sustainable practices are possible through the use of energy harvesting, connectivity and wireless sensor technologies. Many companies are developing various applications with sustainability in mind.
EnOcean has developed wireless switches for light controls. GreenWave Reality, a smart home services innovator, has developed a connected lighting platform. This platform allows control of lighting within residences through sensors, smartphone applications and remote-control. NXP has developed Green Chip technology and is collaborating with GreenWave Reality. Both GreenWave Reality and GreenChip technology are being used by Leedarson Lighting in its energy-saving lighting products.
Wireless sensor networks have been developed to encompass areas and cities. Wireless sensor network companies have installed and monitored factors such as pollen levels, CO2 levels, and occupancy. Libelium of Spain had installed nearly 1000 sensors in cities to gather data to improve living conditions.
'Intelligent' street lighting controlled using wireless communication has been tested in the City of Gothenburg. The lighting level changes according to various external conditions including weather, occupancy and traffic density. Replacing the 18,500 lights in Lund Municipality with the novel technology may help save around $21 million within a period of 20 years, though the initial investment will require approximately $9 million.
Topics on sustainable in energy consumption through technology are to be discussed at the IDTechEx Energy Harvesting & Storage and Wireless Sensor Networks & RTLS conferences to be held from 7-8 November in Washington, DC.
