Controlling lighting via the power line
November 24, 2011 | By Jose Ramon Novoa | 222907633
Intelligent control of large lighting installations, such as street lighting and lighting in office buildings, offers an important way for municipal authorities, governments and large corporations to reduce both carbon emissions and electricity costs. The ideal goal is to deliver the right amount of light at the right time in the right place. In practice, however, today's control of large lighting schemes is often crude: either the bare lamp is controlled by a single switch or dimmer; or a full system is controlled by a single switch or switchboard.
