Titolo: fari che si bruciano...

Ciao ragazzi,
    il mio problema č che si brucia un faro della macchina, sempre lo
stesso.
In alcuni thread ho trovato scritto che le parabole della punto II serie
sono sottodimensionate quindi i fari si surriscaldano.
In altri thread ho trovato che accendendo la macchina con i fari accesi si
possono creare dei picchi di tensione che a lungo andare bruciano i fari.
Ho pensato che potrei mettere o uno zener o un qualcosa di piů specifico per
tagliare sti picchi. Mi ricordo che esistono degli scaricatori non so se
sono a gas, che vengono usati per proteggere dai fulmini le schede.
Sapete qualcosa voi?
Ciao Grazie

Trovato!!!
Ci metto un bel Varistore, ke dite?

secondo me non sono i picchi che bruciano i fari, ma +
probabile il surriscaldamento o al limite,come tutte le
lampade a filamento, il fatto che a freddo hanno una R
molto + piccola che a caldo e quindi assorbono una notevole
corrente di spunto (anche 4 volte superiore) che a lungo
andare "brucia" il filamento.
io ho realizzato un circuitino elementare (trans+mosfet)
per limitare all'accensione questa corrente di spunto.
se ti interessa fammelo sapere.

Interesserebbe anche a me e, come penso, anche a molte altre persone; 
quindi, perché non posti un bello schemino fidocad?
Grazie 1000

Ciao Emilio,
interesserebbe anche a me :) come suggerito già da qualcuno perchè non ci 
fai un bello schemino in fidocad ^___^'
Ciao 

Pensandoci bene, non basterebbe un'induttanza in serie alla lampadina?
In teoria dovrebbe smussare i picchi di corrente.
Poi si potrebbe mettere un condensatore in parallelo per smussare i picchi
di tensione. Secondo voi ci possono essere problemi di risonanze strane?

ciao
io non uso Fidocad, ma circad98 che scrive i files in formato ASCII,
quindi lo posto . per leggerlo basta scaricarsi Circad dal sito
www.holophase.com
quando fornisco V alla lampada (abb o anabb) ,la V viene data con una
rampa di circa 300-400 msec, e quindi la I viene limitata.
ho insertito anche un controllo per la lampada ,se si brucia, scatta
un relè. a chi non interessa togliere tutti i componenti relativi.

  Secondo voi ci possono essere problemi di risonanze strane?
Risonanze strane?? Mah..
Cmq su questo tema si è discusso molto in passato.
Ci sono alcuni casi in cui il problema è docuto alle vibrazioni o al calore
mal dissipato.
In altri casi questo problema, congenito in alcune macchine (
p.es
. la mia
Opel), è dovuto ad un impianto elettrico "eccessivamente efficiente" in
grado di promuovere l'elevata corrente di spunto richiesta dalla lampadina.
La soluzione proposta (almeno dalla Opel) consisteva nella sostituzione di
alcuni cavi di alimentazione dei fari. Questi cavi "speciali" offrono una
modesta resistenza interna (dell'ordine di 1 ohm), limitando in tal modo la
corrente di spunto.
Quindi l'inserimento di una resistenza di opportuno valore allevia il
problema delle frequenti bruciature. Ovviamente riduce anche la luce emessa
dal faro (grossomodo del 10-15%) , ma è una contropartita accettabile.
Per convincervi, misurate la resistenza di una lampadina a freddo e
applicate la legge di ohm per sapere quanta corrente scorre all'accensione..
povero filamento!! :-)

ciao,
ho visto lo schema,
i punti +v abb. +v anabb. sono i cavi che portano corrente alla
lampada giusto? 
quello che non capisco e' la dicitura conn. lampada.
poi la bobina l1 serve solo per la segnalazione lampade bruciate? 
non puoi fare lo schema senza la parte di segnalazione e mettendo i
punti di connessione sullo schema?
P.S. e' meglio fidocad!!!! :-))))
grazie e ciao
