摘要:
A lighting control and dimming system 10 utilizes a single traveler conductor for transmitting analog data signals corresponding to a particular light intensity level of dimmers DIM 1, DIM 2, DIM 3, DIM 4, . . . , DIM N in a dimmer group. A predetermined binary data word is retrieved from the read-only memory of a controller that may be remote from the dimmers, and is transmitted serially in an analog pulse train over the traveler conductor to each dimmer unit. Remote signaling and selection of a specific scene are performed independently of the phase of the applied AC line voltage by sampling the logic values of logic high to logic low and logic low to logic high transitions of a zero cross signal. Dimmers enabled by the transmitted analog data signal produce a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers.
