Abstract
A light dimmer, especially useful for entertainment lighting, provides a high degree of stability in dimmer performance by employing a high level of analog negative feedback and correcting for the undesirable effects on dimmer 'curve' by precompensating the input value while it is digital. A lighting control system distributes both the alternating current supply and control signals representing desired adjustments to fixture intensity via a housing common to multiple enclosures. Each enclosure contains at least one dimmer and mechanically engages the housing, from which it obtains a power input via power contacts and a control signal via an electrically isolated coupling comprising an effective source on the housing and detector on the enclosure.
