System overview 11
The Alien LED Downlight™ system comprises:
1. A driver unit that relays signals from a DMX controller such as the Martin Light Fox™ to the
rest of the system via combined power/data cables. The driver unit also stores stand-alone
programs that it can run on the rest of the system without the need for a DMX controller.
2. A ‘head’ consisting of:
a. A transformer/receiver unit that accepts power/data signals from the driver unit and applies
variable intensity power to the different colored LEDs in the downlight or downlights
connected to it.
b. Either one high-power or two standard model IP67-rated downlight luminaires.
