Headlight conversion

[Gwenadu]

From [www.osram.fr[/url]: I suppose you could find the same explanations in english, somewhere by Google (Antti ).
Question flux lumineux : Combien de temps faut-il à une lampe au xénon pour atteindre 100% de son flux lumineux ?
Réponse : Environ 30% à l'allumage, environ 80% après 5 secondes, 100% après environ 1 minute

Question puissance : Quelle est la puissance absorbée pour un projecteur ?
Réponse : Entre 40-45W dont 35W pour la source de lumière

Question allumages et extinctions : Combien d'allumages et extinctions une lampe au xénon et son ballast peuvent- ils supporter ?
Réponse :
La durée de vie des lampes de projecteurs au xénon dépend essentiellement du nombre d'heures de fonctionnement et aussi du nombre d'allumages.
Une lampe au xénon supporte facilement plus de 20000 allumages et extinctions. Ce résultat fait suite à des tests de survivance normalisés. Sur un véhicule où on solliciterait très fréquemment les codes on pourrait atteindre des valeurs dépassant les 50000 allumages et extinctions.
Quant au ballast, la règle veut qu'il supporte plus de 50000 allumages et extinctions

Question tension : Quelle est la tension d'amorçage des lampes de projecteurs au xénon ?
Réponse : Les tensions d'amorçages se situent entre 10 et 20kV avec des impulsions très courtes (< 1msec.)

Question intensité : Quelle intensité traverse le circuit et quelle est son évolution pendant la phase d'allumage ?
Réponse : La phase de mise en route (allumage et stabilisation) d'une lampe au xénon est complexe et le courant varie beaucoup également suivant le type de ballast employé.
En général au moment pendant la phase de démarrage après l'enclenchement de la lampe au xénon il circule pendant quelques secondes un courant d'environ 2.6A (typique : 2 - 3 sec.).
Dans les 30 secondes qui suivent, le courant baisse de manière exponentielle jusqu'à une valeur de l'ordre de 0.4A.

Question tension/bornes : Quelle est la tension aux bornes de la lampe au xénon quand elle est stabilisée ?
Réponse : La tension d'arc de cette lampe est de 85 V (nominale).

Question température : Quelle est la température de surface de la lampe au xénon ?
Réponse : Le brûleur en quartz peut atteindre un température maxi. de 700 °C .

Question durée de vie : Quelle est la durée de vie d'une lampe de projecteur au xénon ?
Réponse : Dans le secteur de l'automobile la durée de vie moyenne de cette lampe est de l'ordre de 3000 heures.

Luminous flow question: How long is it necessary for a lamp with xenon to reach 100% of its luminous flow? Answer: Approximately 30% with lighting, approximately 80% after 5 seconds, 100% after approximately 1 minute.

Power question: Which is the power absorptive for a projector? Answer: Between 40-45W of which 35W for the source of light

Lightings question and extinctions: How many lightings and extinctions a lamp with xenon and its ballast can they support? Answer: The lifespan of the lamps of projectors to xenon depends primarily on the number of operating hours and also on the number of lightings. A lamp with xenon supports easily more than 20000 lightings and extinctions. This result followed upon standardized tests of survival. On a vehicle where the codes would be very frequently requested one could reach values exceeding 50000 lightings and extinctions. As for the ballast, the rule wants that it supports more than 50000 lightings and extinctions

Tension question: Which is the tension of starting of the lamps of projectors to xenon? Answer: The tensions of startings are between 10 and 20kV with very short impulses (

Intensity question: Which intensity crosses the circuit and which is its evolution during the phase of lighting? Answer: The phase of startup (lighting and stabilization) of a lamp to xenon is complex and the current much also varies according to the type of ballast employed. In general at the time during the launching phase after the interlocking of the lamp to xenon it circulates during a few seconds a current of approximately 2.6A (typical: 2 - 3 dryness). In the 30 seconds which follow, the current drops in an exponential way up to a value about 0.4A.

Tension/bornes question: Which is it the terminal voltage of the lamp to xenon when is stabilized? Answer: The tension of arc of this lamp is of 85 V (nominal).

Temperature question: Which is the temperature of surface of the lamp to xenon? Answer: The quartz burner can reach a maximum temperature. of 700 °C.

Question lifespan: Which is the lifespan of a lamp of projector to xenon? Answer: In the sector of the car the average lifespan of this lamp is about 3000 hours.

Hey You "Gwenadu", I dont use Google AT ALL !!!!... all come from my head... I am electrician... ... and if someone dont accept it, then its not my problem anymore... I only want help Paso guys...

Cool , Antti! Sometimes, Google can also help Pasoguys . But I agree that it is more pleasant to share our own experience about the Paso .
I think that we have not to hurry to buy a Xenon kit. The price is 1/2 lower since last year.
on my headlights I will use 2 H7 bulb "Philips night-guide".
next week I will see much better... I hope!

to add to the discussion:
as mentioned before Xenon bulbs only have one filament.
There are though Xenon lamps used in newer cars like i.e. AUDI which use bi-Xenon lamps. The can produce lo and hi beam. The trick is that the Xenon bulb always runs at full power but there`s an electromagnetic shutter infront of it that covers a part of the bulb/reflector. This is also the only way you can "flash signal" with your hi beam. A Xenon bulb would be to slow to react.

One thing that is not considered in this discussion is the matching fit of bulb, reflector and lens.
Xenon/HID lamps are designed in a total different way than the usual car/bike front beam.
If you take a look at 2 identical cars one with Xenon and one without you will notice that the lenses are different. lenses in general have a certain pattern on them to cause a certain cone of light. Just replacing the standard bulb with a real Xenon kit will for sure improve light but also lead to diffuse and (if the online translator is right) adventitious light which will lead to bedazzle other drivers. For these reasons (at least in Germany) these kind of interim solutions are not legal.
Xenon is also more sensitive about dirt on the front lens as this will create flare that you as driver won`t notice, but the other drivers will.

So, this modification wouldn't be permitted in all EU, since the rules of the road are the same.

We have to find another solution to improve the lighting.

There are also some "local rules" in every EU country.... At least some very stupid in Italy(what is EU country), like, that You cant wave Your hand to another mc driven in traffic without penalty.... I have writed(copy/paste) about it to Paso.org site earlier.... :funny: :funny: :funny: Anyway, its very nice, that here in Finland polices DONT have enough time to measure Ducati exhaust "noises" in streets... :funny: :funny: :funny: :funny:

... double H4 headlight(reasonable coasts) with extra realays to low and high beam(to not overload original wires) with extra switch(in 907IE to keep battery up)....

I think, allways have to think, what are coast of modification also(thinking quite low coast mc, like Pasos are)... ...What is wise and what is not....

[paso750]

Francesco,

a friend of mine has 2 Cagiva Elephants. Those bikes have dual front lights. His light was also not that good so he modified the wiring, put in relais (as mentioned by Antti before) and cleaned the inner side of the lens.
To do this he removed the headlight, laid it down with the lens downwards and threw in a cotton ball. Then with some chopsticks he removed all the dust that built up inside of the lens. That made quite a difference.
You need to be very careful though not to touch the reflector and use a dry cottonball, not one soaked with any glass cleaner !

I have done that cleaning job to some (4) ST2 bikes. Then need to cut with sharp knife lens to 2 pieces, then cleaning easily and again "weld" with silicone pieces together, VIOLA ! NO "moisture" anymore. Ducati changed huge amount of ST2 light in warranty time without knowing, what to do! ...little stupid from Ducati! That "moisture" came from new plastics in lamp.... One time cleaned after one year, not anymore that "moisture"... :funny:

Btw, i use Elephant lights, cause they are enough good with reasonable price. Happy with result, as U see: :laugh: :laugh: :laugh:

[persempre907]

There are also some "local rules" in every EU country.... At least some very stupid in Italy(what is EU country), like, that You cant wave Your hand to another mc driven in traffic without penalty.

Some rule can be different, but not the ones about the vehicles' homologations (EURO 1, 2, 3, 4, 5 etc.)

The rules can be smart or stupid, but even if it's enacted a stupid rule the most important thing always is HOW it's applied.

In fact, the laws come from the men, and the men can be smart or stupid. Really, the very bad thing is when a stupid law is silly applied...

So it's true, in Italy the law don't allow to leave the hands from the handlebar.

But here no policeman will fine you if you open the helmet visor in the summertime (so you leave an hand from the bar).

But, if you are doing a wheelie with only one hand he'll fine you (and it seems to me right).

So don't worry, came in Italy with your baby, even if with your open pipes you would have to take care...

I never thought about it.... but it's a thing so simple... I'll try!

[paso750]

Antti,

what do you mean you cut the lens and glued that back together ? That`s scaring me.
I guess you only seperated the glass lens from the reflector/housing, right ?

G.

[Finnpaso]

You are right. (as Germans normally...) Normally they are(ST modells!!!) "glued" by some very similar to silicone, so need to cut that silicone only and then You have all that in 2 pieces. Easy job! :laugh: In Paso its much more difficult and i dont do that to Paso lamp at all... Those newer Ducatis are better designed motorbikes...

[Marinus]

Is it not a possibility to run one big cable from the battery to the front, then split to two relays. One for high beam and one for low. Placing the relays as close to the headlight as practical then run thicker wires to a 100w bulb?

Would this cause any problems?

All this would cost is some wire, a fuse by the battery, 2 relays, a bulb and some time.

I have my bike stripped of fairing at the moment so would be a good time to do it.
