LED Lights

Phoenix started making underwater LED lighting in 2002 when we designed and built the first pressure tolerant, full ocean depth LED lighting system. We have designed, built, tested, and operated both oil filled and potted versions of our LED lights down to a depth of 8230m (27000 ft).

Phoenix designed LED lights are being used with our commercial diving division on our Atmospheric Diving Systems (ADS) and ROV fleet of which many are rated to 6000m. Our lights have been used on expeditions inside the Titanic, and Deepwater Horizon, and many others.

Phoenix LED power supplies use constant current sources with dimming control using either RS232, RS485, 1-wire, PWM and analogue signals. Power supplies may be stand alone units or built into the light to fit the requirements. All Phoenix LED lights are designed for flicker free illumination and are suitable for SD and HD video systems.

Diver safety is of upmost importance and Phoenix providesadopts several methods, in both in hardware and software, to protect the diver from the risk of electric shock. Safety features include low supply voltage, with shut offs for over voltage, over current, open circuit detection, and over temperature. The Phoenix intelligent DSP controlled units also have auto sense capability which allows the user to connect any of the range of Phoenix LED lights to the power supply which will auto adjusts its output to the LED light. Phoenix LED power supplies are compliant with the AODC 035 safety guidelines.

The LED’s used in Phoenix LED light are chosen for color temperature (typically 6500 K) and high optical efficiency (100 lm/W). The LED mean time between failure (MTBF) isof LED’s, typically >50000 hours, which makes them more attractivemore attractive for underwater lighting applications than incandescent or halogen lamps which havinge only a few hundred hours or less of life. Other benefits of LED’s include much higher efficiency and resistance to shock as compared to filament lamps.
