Strobe lighting control system
First Claim
1. A control system for a strobe light that operates on alternating current, the control system comprising a first processor for recognizing commands and a second processor for executing commands which have been decoded by said first processor, the control system further having a detector for detecting zero voltage crossing points in cycles of the alternating current, said second processor using a selected said zero crossing point to control the intensity of the light emitted from the strobe light by delaying firing of the strobe light in each cycle at least through a base delay that determines the maximum intensity of the light, until the cycle reaches a predetermined point from the base delay of the cycle, the predetermined point being identified by decrementing at least one digital counter.

Abstract
A system for controlling a strobe light or the like with serial data has a first processor for decoding or recognizing commands, and a second processor for executing the commands. The serial data is typically in a standard format such as DMX-512. Also, firing of the strobe lights is controlled digitally, for precise control over both timing and intensity.

6. A strobe light that operates on alternating current comprising:
-
a strobe lamp capable of emitting light at a predetermined speed and intensity;
a power source for said strobe lamp;
a first processor for receiving and recognizing commands for the strobe light;
a second processor for executing commands which have been decoded by said first processor, said second processor controlling the power source to the strobe lamp in accordance with the commands; and
a detector for detecting zero voltage crossing points in cycles of the alternating current, said second processor using selected said zero crossing points to control the intensity of the light emitted from the strobe lamp by delaying firing of the strobe lamp in each cycle at least through a base delay that determines the maximum intensity of the light, until the cycle reaches a predetermined point from the base delay of the cycle, the predetermined point being identified by decrementing at least one digital counter. - View Dependent Claims (7, 8, 9, 10)
