Saab develops new high-intensity LED

UK, September 5, 2009

Saab Seaeye, a top manufacturer of a range of electric powered ROV (remotely operated vehicle) systems, has developed a super-intensity low power light that features a new thermal control that avoids failure through overheating.

This is the coolest-running deep-rated LED (light emitting diode) light in the world, according to a statement.

Telemetry or PWM (pulse width modulation) controlled, it monitors its status and gives data feed-back on current, input supply voltage, LED voltage, LED temperature and light output percentage, so is ideal for providing data for the diagnostic capability of the new generation of control systems.

The LED light brightness can be controlled over its full range of brightness and retains a constant colour temperature over the range compared with tungsten halogen, which varies considerably when dimmed.

Rated at 6000 metres, the new LED light joins Saab Seaeye’s 3000 metre rated technologically advanced range of LED lights especially developed to bring extra reliability, low power consumption and greater luminosity to underwater systems.

This means that in addition to bringing greater luminosity performance to ROV operations, underwater system developers worldwide can incorporate this range in other underwater equipment designs such as diver equipment, as it has a universal power interface that can take a wider range of power options than any other LED light.

A mounting arrangement to provide horizontal and vertical adjustment of the light position is also provided.

Dave McInnes, Saab Seaeye’s electronic design engineer behind the concept, said the new LEDs are far superior to both halogen and incandescent lamps.

“They use a quarter of the power, have a life of over 50,000 hours compared to 1000 hours for halogen and give higher luminosity than a 150 watt bulb - with a daylight white for more accurate colour rendering of video images than the typical ‘yellow light’,” he explained.

McInnes added that they are more robust than other lighting systems.

The new range of LED lights is being fitted to all Saab Seaeye ROV systems, the statement said.-TradeArabia News Service
