Xenon technology - The new standard for deck lamps<br />
Xenon technology represents the present peak in lamp system<br />
development. The advantage of xenon lamps in comparison<br />
with halogen lamps lies in their light flux, which is 2.5 times<br />
higher (with 35% lower energy consumption). This leads to very<br />
high luminance and therefore brighter and wider illumination of<br />
the deck. The colour of the light is similar to that of daylight. A<br />
considerable increase in comfort and active safety. The<br />
triumphant march of this new light is unstoppable. Whilst only<br />
expensive luxury cars were equipped with xenon light a few<br />
years ago, this technology is now also available in Hella Marine<br />
deck lamps.<br />
What is xenon light really?<br />
Instead of a coiled filament, a light arc is the light source in<br />
xenon lamps. The bulb, which is only the size of a cherry stone,<br />
is filled with xenon gas and metal salts. In order to ignite the<br />
xenon bulb, an extremely high voltage of approximately 20,000<br />
volts is required. This is provided by an electronic ballast: 12 or<br />
24 volt direct current is transformed into 20,000 volt alternating<br />
current. A light arc is created at temperatures of around 5000°<br />
C. With a power consumption of a mere 35 watts, this<br />
generates 2.5 times the light flux of a halogen bulb with 35 W<br />
output. The current generation of control units is only half the<br />
size of, and approximately one third lighter than, the first and<br />
second generation. The ignition electronics can now be<br />
completely integrated into the control unit. As a result of these<br />
control units, the lamp’s light is almost independent of voltage<br />
fluctuations in the ship’s electrical system, as the electronics<br />
operate the xenon bulbs at constant output.<br />
