According to a report, increasing emphasis on reducing costs and commissioning is promoting the use of more distributed lighting control architectures with fixture-level control.
Traditional control panels that apply dimming and switching to an whole zone or series of fixtures have been the most common form of lighting control. At the same time, all the fixtures in the zone are dimmed, or switch on and off. Fixture-level control is achieved by controlling the individual ballasts and drivers, which enables users to switch or dim individual fixtures, rather than entire zones.
Some lighting solutions connect each fixture individually to the controller or control panel, and others have the controller and sensor built into the lighting itself. With fixture-level control, more connected switches and sensors are required to cover each additional area. The report estimates that nearly 9.5 million connected switches where shipped to commercial applications in 2014. By 2018, as fixture control gains in popularity, 18.3 million connected switches are expected to be shipped to commercial applications.
