ABSTRACT:
An electrical go-go light belt includes a sawtooth or step-wave generator. The sawtooth or step-wave is transmitted to a lamp section via a drive line, the voltage of the rising sawtooth or step-wave being supplied to a voltage divider to trigger silicon controlled rectifiers and turn on any bulbs that are connected in series with the rectifiers one by one. The rearmost bulb in a preceding lamp section is turned on to trigger the sawtooth or step-wave generator of the relay circuit of the next lamp section so as to turn on the bulbs of that section, the last bulb of which triggers the sawtooth or step-wave relay of a further section, and so forth. A control system regulates the frequency of the sawtooth or step-waves emitted by the sawtooth or step wave generator of the current lamp section, and the relay circuits, in order to control the rate at which bulbs are turned on. When the rearmost bulb of the last lamp section is turned on, the turn-off system is triggered to output a turn-off signal to the control system, and the control system outputs a low voltage to make all the bulbs of the belt turn off. When it is desired to add more lamp sections, it is simply necessary to install additional relay power supplies, permitting the belt to be extended indefinitely.
