Safer Driving with Hella’s Advanced Technology
 
Lights with Parabolic Reflector Systems
These Lights are designed with a reflector in the mathematically defined shape of a paraboloid. The reflector captures the luminous flux emitted by the bulb and reflects this forward as an almost parallel light beam.

The specific light distribution is produced by optical lenses and prisms in the profiled cover lens which precisely directs the light to the area to be illuminated. Good optic design produces an evenly lit surface whereas spotty appearance is the result of optics of lesser quality.

Very efficient headlamps with Parabolic Reflector Systems require a large reflector in order to capture the maximum luminous flux from the bulb.

Parabolic
Lights with Free-Form (FF) Reflector Technology
Lights incorporating Free-Form (FF) Technology are based on complex mathematical calculations. Over 50,000
individual surfaces of the reflector are calculated and formed to precisely reflect the light to the road in front of the vehicle. The outer cover lens contains minimal optic elements.

A well designed headlight based on Free-Form (FF) Technology produces a very evenly lit area in front of the vehicle which significantly contributes to safer driving.

Spread Beam (for a full field of vision)
The functional principle of a DE ‘Diaxial Ellipsoid’ lamp is similar to that of a slide projector. An ellipsoid Free-Form (FF) reflector directs the light to a focused glass lens, which bundles and projects it onto the road. A shield positioned between the reflector and the lens provide a very sharp cut-off. The result - concentrated light output with a clear cut-off ensuring a smooth light distribution with very little stray light. DE Technology allows smaller dimensions with a higher luminance compared to a parabolic lamp.   The Spread Beam driving lamp provides good illumination of both – the area immediately in front of the vehicle and the distance ahead. Particularly suitable for road vehicles, such as trucks and buses – when fatigue-free driving is more important than recognising objects in the distance.
     
Pencil Beam (for long-range illumination)

 

Hella Fog Lamps (for safe driving in inclement weather)
The Pencil Beam driving lamp is designed for maximum
long-range illumination, providing improved visibility of objects and traffic situations further in the distance.
Particularly suitable for off-road vehicles – when objects further in the distance must be recognised quickly to
maximise reaction time for the driver.
  Fog, rain or snow can reflect the light of standard driving lights back into your eyes, creating a dangerous glare that makes it difficult to recognise hidden hazards.
Hella fog lamps are equipped with specially designed reflectors, which evenly illuminate the width of the road, providing you with a wide path of light for more safety through clearer visibility. Particularly suitable for any vehicle driving through humid or moist areas where fog, rain or snow is common.
