DS-PRO LED

DS-PRO LED Scuba Diving Lights are designated to professional and technical divers who insist on a reliable and rugged lighting source. This is the a new generation, using the world leader, Luxeon® K2 TFFC popower LEDs, which bring additional features. Lamp head makes it possible to be carried on the hand by Goodman holder, or on a helmet or on a photo/video equipment arm.
Lamp parts are made from high quality material which is sea water and sun resistant.

LED vs. HID Advantages:

  • Contrary to HID, it is easy to continuously control the LED brightness. So it is possible to introduce a low power mode to the: 100 and 20 per cent intensity, together with 5 times loger lightiny time.
  • The white LED spectrum is more continous to that of HID lamp, and gives more color fidelity.
  • The LED array uses a precise optic collimator to form the beam, with better quality of the radiation angle and better efficiency.
  • LED, when cooled properly, has much longer lite time and lower failure rate, as well as better mechanical ruggedness, using no glass.
  • No need to ignite the arc, waiting for temperature adjustment and complex arc control. LED can shine at full brightness immediately.
  • The LED life is independent on number of starts, in contrary to that of a HID tube.

An array of seven LED lamps of the Philips Lumileds LUXEON® K2 typ with TFFC technology offers the parameters second to none. The pictures below show the HID versus white LED spectrum as measured in our lab. The HID contains several spectral lines - peaks for several narrow bands - colors while the rest is very weak. Although the human eye "sees" the complex as white, some colors are missing, so when you liht on a red object, it looks dark, or brown, for example. It is similar for the green to blue range where the HID has a marked minimum. Note that the white LED in fact is composed from a blue chip and a wideband, yellow centered luminophore, the wider band the better.

The DS PRO LED can utilize two levels of light power, full (100%) and low, one-fifth power (20%). In the low power mode, just air cools the lamp sufficiently, so it will shine permanently at all conditions and the lamp will not overheat. At full power, the handpiece temperature rises if the lamp is not cooled and soon the temp sensor causes switching to low power. Low power also causes extending the lighting time by a factor of five. If, at full power, the battery becames almost empty, the status is indicated by four times switching between full and low power.

LED Display LED display

The intelligent lamp controller indicates the statuses by a two-digit LED display in the canister lid. Thanks to it, you know how long the lamp will shine, or how long the charging will take. The display also indicates possible problems inside the lamp and condition/temperature of each of the two batteries inside.

Smart Charging Smart Charging

Integrated Smart Charging System implements advanced charging and cycling algorithms provided by the battery manufacturer. Thanks to it, maximum battery life and cycle number can be achieved, as well as shortest time for charging, under actual conditions. Second to none feature: no need to open the canister for charging: just plug the banana to smart isolated socket on canister top. Nothing to open and no risk of flooding the battery after incorrect re-closure.

Collimator Lens Collimator Lens

The light beam radiation angle is selectable by installing the right focusing (collimator) lens. Two values, ±6°(12°) a ±25° (50°) of beam angle are available. While the wide beam is more suitable for clear water, narrow beam fits better to "black" waters and to wreck and cave diving.
Contrary to collimator, the reflector does not put all the light from the source to the desired direction. Some part of the light is not directed to desired direction. It may cause blinding of another diver or disperse back in waters with poor visibility (dirt, plankton). It is similar to high beam car lights in fog. Using a collimator, most of light is directed forward almost parallel, so the beam has greater intensity and the radiation pattern has no side lobes, the diver can see further.
