Advanced Underwater LED Power Supply and Light Control

2017-02-03T20:03:10+00:00 May 20th, 2010|Technical Resources, Underwater Imaging|

While great attention is given to LED solid state devices during their rapid evolution, they are just one component in a larger electronic circuit. LEDs are tiny, fragile devices that will be easily damaged if allowed to overheat or if exposed to excessive voltage or currents. These devices need an external electronic circuit, commonly called a driver, to safely control the power applied to them. This article will look at the driver circuitry behind the light emitters.

Color Purity of LEDs

2017-02-03T20:03:58+00:00 December 14th, 2009|Technical Resources, Underwater Imaging|

The term “Color Purity” often invites inquiries from customers viewing the spectral graphs generated by our integrating sphere. Color Purity was specifically created for LEDs with the 1997 CIE 127 Document and does not apply to any other type of light source, such as HID, HMI, CFL, or incandescent.

Advances in High Brightness Light Emitting Diodes in Underwater Applications

2017-02-03T20:09:45+00:00 October 20th, 2008|Underwater Imaging|

Light Emitting Diodes (LEDs) continue to make headway in the undersea world as efficient and durable light sources. Undersea lighting designers continue to follow the rapid development of LEDs for general commercial illumination. In addition to improvements in LED technology, electronic drivers have become more compact and increasingly efficient, providing options to end users for thermal roll-back, dimming, AC/DC, or variable voltage input with constant current output.

Application of High Power Light Emitting Diodes for Submerged Illumination

2017-02-03T20:10:11+00:00 February 20th, 2008|Underwater Imaging|

High Brightness Light Emitting Diodes (HB-LEDs) are a reliable, efficient, compact, and robust light source for underwater applications including diver, ROV, AUV, free vehicle, and manned submersible platforms. LED lights are capable of single color or full daylight spectrum, offering unique solutions to oil field and other commercial problems.

Solid-state Lighting Comes of Age in the Deep Sea as High-Power LEDs Debut on dives by the submersible Alvin. LED-based lighting has seen significant performance improvements recently and is moving from specialty and indication applications, such as traffic signals and flashlights, to general home and business lighting applications. DeepSea Power & Light recently tested its underwater LED SeaLites on Alvin, Woods Hole Oceanographic Institution's (WHOI) manned submersible.
