Section 1: Overview
The Dialight Catenary White Strobe Driver and Flash Head is designed to be
incorporated into Medium Intensity L866 systems for the lighting of structures
supporting overhead cables above canyons, valleys and waterways, as specified
by the FAA.
This design uses LED technology for light output both from the Beacon and
White Strobe. Unlike conventional xenon flashtube technology, little or no
maintenance is required during its lifetime. Working voltages of less than
200VDC are much lower than those of xenon flashtube designs; therefore, this
system represents an advance in safety.
A high level of functionality and versatility is provided by the Driver module. Not
only does it generate the required LED drive currents, but also provides:
Timing and synchronization
Fault monitoring
Dimming features
Options for night operation
Serial port configuration
Data logging
The Driver module consists of a plate on which are fixed (See Diagram):
(W1 and W2) Two White Strobe Drivers
(R)
One Red Beacon Driver
(M/F) One Microcontroller / Filter / Protection and Interface module
(CAP) One Capacitor module
(TB) One Terminal Block
The system operates from a nominal 48Vdc/150W supply.
Switches on the micro-controller board allow various options as to how the
system operates to be selected.
