Good visibility on the road at night – one of the most important factors of safety. In modern expensive cars set innovative LED units that are controlled charging electronic complex with advanced intelligent features. However, the coverage of the budget models of machines can also be improved. Such an upgrade can start, for example, installing instead of halogen light sources Xenon or bi-xenon lamps.
What distinguishes the design of xenon and bi-xenon lamps?
Improvement of aspiring motorist coverage begins with the usual replacement of light bulbs in the headlights. And at that moment he was faced with the question: what high-brightness lamp is better to replace staff halogen? Have to choose between xenon and Bi-Xenon. The main difference between these two classes of lighting devices – is first of all modes of operation. What does this mean?
Usual xenon lamp is used only in the low beam (if the optical design has not undergone further improvements). Xenon light source can operate in a mode of low beam, and far.
Operating modes in the bi-xenon system, switched due to the fact that it itself is luminous arc can change its position. Structurally, this is achieved as follows. Inside the lamp envelope is a movable body in which the electrodes are located. The electronic device controls the movement of the housing in the flask and thus the luminous arc configuration changes.
In a conventional xenon lamp electrodes located inside the stationary housing in a flask, and change its position can not.
When selecting the light source must also consider the structure and type of lights that are installed on this model car. For example, in one-piece headlights and headlight beam are combined in a single lamp, and separate – for near and far Lighting fixtures are separate. Thus, dual-filament lamps bulbs can be changed only on the bi-xenon, and xenon own dual-mode light sources can be installed in separate fixtures.
Which is better to choose light sources: Xenon or bi-xenon?
Many motorists who passed after galogenok on bi-xenon lamps note that the appearance of light at the far light has not changed, although the bulbs shine much brighter (some even notice that the lighting even more deteriorated). The explanation of this paradox is in the nature of bixenon and largely depends on the design of the headlights:
• Light of from the xenon lamp is dissipated more rapidly due to the fact that the frequency of electromagnetic waves of the light wave of the color temperature is higher than the “warm” halogen
• Headlamps with halogen bulbs usually are not put lenses, but they need additional lens to fully illuminate the passing portion
• Lower the brightness of the light spot in front of the vehicle due to the use of the high xenon light in combination with conventional lamp lights, which is designed for regular halogen.
For these reasons, it is not recommended installing the bi-xenon lamps without making changes to the professional structure of the lights. Professional lamp for completion mono-xenon lamps is much cheaper, but they can be used only if the vehicle have separate lights for low and high beam.
For correct installation of a xenon lamp in the headlamp, designed for halogen, you must first install the collecting lens and polish the lens (this is done to remove elements for low beam).
If mono-xenon lamp is mounted correctly, the focusing of the light flux increase, which will provide additional light intensity. At the same time such coverage will not dazzle oncoming traffic. Complete with mono-xenon lamp for high beam is better to use regular halogen.
If the car set-piece fixtures, it can not be choosers – bi-xenon lamp in this case will, of course, better. However, there is another opportunity for mono-xenon lamps in these fixtures. This requires some spotlight to modernize itself by setting her bi-xenon lens. It is necessary to take into account:
• After installation, this lens can be used only mono-xenon lamps
• The lens is placed “blind”, which is controlled by a separate button
• lens housing differ according to the type of the cap
• The lens is mounted on the body of regular halogen lamps through universal spacers
In such lamps and dipped beam work more efficiently. Switching between modes is faster and does not have additional flash.Thus, a sharper focus generates a light spot of the correct geometry.
Conclusion: The choice of color temperature characteristics
For motorists need to remember that the color temperature of halogen lamps and xenon is different. Halogen gives yellowish light of low temperature (3000 – 3200 K). In the xenon light bluish (4 300 – 12 000 K).
The higher the temperature, the faster your eyes get tired. Experts have determined that it is best adapted to human vision white light with a faint yellowish tinge, which corresponds to the color temperature 4300 – 4800 K.
