摘要： A light dimmer with semiconductor power devices coupled between an alternating current supply and a lamp load, in the course of varying average power supplied to the lamp load, transitions the power devices under load between one and the other of substantially conductive and non-conductive conditions, increasing the duration of the transition by the power device itself from the minimum possible duration to reduce generated EMI. Undesirable effects of the high current demands of cold lamp filaments are reduced by initially increasing the conductive portion of half-cycles, relative to the proportion required to produce the desired amount of average power, while avoiding transitions at phase angles that would produce excessive losses. A transition shape may be employed in this mode and in normal operation that maximizes audible lamp noise suppression for a given level of thermal losses.

摘要： 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.

摘要： An electronic dimming apparatus includes a semiconductor power controller which couples a lamp to an alternating current source and variably controls the average power supplied to the lamp by adjusting the relative proportion of each half-cycle in which the power controller is in a conductive condition. The semiconductor power controller is controlled by the output of a transition controller which in turn is connected to a triggering circuit. The triggering circuit is responsive to a first input condition corresponding to desired average power and also responsive to the zero-crossing of the alternating current waveform. The transition controller gradually changes the condition state of the semiconductor power controller between non-conduction and conduction and controls the voltage across the lamp load to maintain a stable rate of voltage change despite lamp impedance variations, thus reducing electromagnetic interference.

摘要： In a lighting console which provides outputs to dimmers which include master controls for at least two scenes and channel controls for each of a plurality of channels with the channel controls including at least a first and second scene preset potentiometer, the channel controls and master controls cooperating to allow presetting, and which also includes a buss, with one of the preset potentiometers for each of a plurality of the channels connected to the buss and an output from the master controls being used through suitable amplifiers to drive the buss, a plurality of nondestructive current limiting fault isolating devices are provided for each scene, each connected between the master and at least one of the preset potentiometers for that scene. As a result, the effects of a fault causing abnormal currents to flow which develops after the fault isolating means will not disrupt the operation of channel potentiometers connected to other fault isolating means. In addition, the console permits the separation of the assignment selection of potentiometers and the assignment indication of that selection. The console also includes distributed multiplexing devices which reduces the back plane wiring requirements in the console.
