摘要： A diagnostic apparatus for use in a light dimming circuit of the tape which selectively controls the current flow through a lighting load to adjust its luminous output. The dimming circuit has a controllably conductive device, such as a triac, connectable in series between an A.C. power source and a lighting load, and a control circuit which responds to a dimming level control signal to selectively apply a selected portion of an A.C. voltage waveform produced by the A.C. power source to the lighting load to adjust the RMS voltage across the load. The selected portion is determined by a firing angle at which the control circuit causes the controllably conductive device to conduct power during each half cycle of the A.C. waveform. The diagnostic appararus has a senior to sense the operating status of a component of the dimming circuit and/or the presence of the dimming level control signal. A logic circuit compares an output of the sensor to provide an indication of the present operating status of The component and/or the presence of the dimming level control signal. A status indicator responds to the output of the logic circuit to provide a visual indication of a change in status of the component and/or presence of the dimming control signal.

摘要： A dimmer panel for controlling the intensity of a plurality of electric light sources includes a plurality of dimming circuits. Each dimming circuit has a control circuit, a heat producing controllably conductive power switch such as a triac, and a heat producing coil such as a choke. The power switches and coils are arranged on a corrugated heat sink to minimize component temperatures in the dimming control circuit and of the power switches. The heat producing coils are remotely located from the control circuit and the power switches, so that the heat generated by the coils does not increase the temperature of the components in the control circuit or of the power switches.

摘要： A lighting control system operates to control multiple zones of lighting through multiple dimming circuits so as to achieve any one of several desired lighting scenes. The system includes a plurality of wallbox control units which collectively operate to multiplex digital lighting control information on a communications link. Each wallbox control unit includes a plurality of zone-intensity actuators which are manipulatable to alter the information transmitted by their respective wallbox control so as to vary the lighting intensity of an associated lighting zone. A central lighting control panel includes a microprocessor adapted to receive and processes the multiplexed information transmitted on the link, and re-transmit digital lighting control information, on a second multiplex link, to the dimming circuits. According to one aspect of the invention, the microprocessor is programmed to assign a preselected dimming circuit to any one of the zone-intensity actuators when that actuator is manipulated according to a predetermined sequence.

摘要： A phase controlled dimming system having an active filter for receiving the AC line voltage waveform, and for recovering the AC fundamental waveform therefrom is disclosed. The recovered AC fundamental waveform is supplied to a zero crossing detector that provides zero crossing indications of the AC fundamental waveform. The recovered AC fundamental is substantially free of noise or distortion, and of frequency components greater than at least second order harmonics, that may be present on the AC line voltage waveform, and that might otherwise result in faulty or incorrect zero crossing detection. An output of the zero crossing detector is supplied to a microprocessor that controls the gating of a controllably conductive device interposed between the controlled load and the AC source based on the zero crossing information. The filter may take an analog or digital (software) form.

摘要： Reverse phase-controlled dimming of an a.c.-powered load is accomplished by switching power to the load on and off during each half cycle. In one embodiment of the present invention, power is switched on when line voltage is substantially equal to load voltage and off at a selected time later in the half cycle or at any time that the voltage across the switch exceeds a predetermined value. Preferably, switching is accomplished with a pair of field effect transistors. The load preferably includes a capacitor from load hot to neutral. The present circuit permits quiet dimming of incandescent lamp loads without the need for complex circuitry. It is particularly well adapted for dimming low voltage lamps using a solid state transformer.

摘要： A dimming system, which provides a time-varying current from a power source between the electrodes of a gas discharge lamp, simultaneously provides high-frequency, low-level current between the electrodes to sustain an electric discharge in the lamp when the time varying current alone is insufficient. The system provides reduced starting stress in the lamp and, therefore, longer lamp life by delaying the formation of an arc discharge, during start-up, until the electrodes have been heated. The system can be used with standard magnetic ballasts to provide full-range dimming of gas discharge lamps from 3 to 100 percent light output with minimal striations, lamp drop out, and flicker.
