LED lights for Deepsea Challenger submersible

Made
These LED components are part of a number of objects related to the design and development of the submersible vehicle, Deepsea Challenger, that was used by James Cameron in his historic descent to the bottom of the Marianas Trench in March 2012.

These LED lights illuminated the ocean floor and surrounds for the pilot of the submersible. Similar to the design challenge of the batteries, these LEDs would need to survive exposure to never-before experienced depth pressure. Allum met this …

Production

Notes

Designed, sourced and assembled by Acheron Pty Ltd, NSW, 2012 these materials made up the LED lights which illuminated the ocean floor and surrounds for the pilot of the submersible. Similar to the design challenge of the batteries, these LEDs would need to survive exposure to never-before experienced depth pressure. Allum met this challenge with a diaphragm compensating system, which similar to the bladder compensating pressure system, allows silicon fluid to fill any air pockets to relieve the pressure on the object. They were housed in a cluster formation outside the life support sphere, and in close proximity to the battery cells that powered them.

History

Notes

Where experiments with electroluminescence began as early as 1907 with British experimenter HJ Round, the LED, or light-emitting diode, was first patented in 1967 by Texas Instruments employees Robert Biard and Gary Pittman. Initially quite expensive to produce, the chip fabrication and innovation in packaging achieved by Thomas Brandt in the 1970s allow for them to be produced much more cost effectively. They are valued over more incandescent lighting systems in that they "boast lower energy consumption, a longer lifetime, improved physical robustness, smaller size and faster switching."
