Les spots led ont bien baissé en prix depuis ce topic.
Pour moins de 3€, Il y a ça en 12v 3W

Ca éclaire 30W quand même !

Salut,

Je me suis bricolé ça dernièrement : un feu à LED alimenté par le volant magnétique.
J'ai monté une seule LED de puissance, pour garder un style proche de l'origine.
Résultat : c'est très efficace, on voit parfaitement le feu, même en plein jour.

Le montage à réalisé fait dans un cabochon refabriqué, je posterai plus de détails si ça intéresse du monde.

Wof, c'est plus pour le fun qu'aut' chose.
L'idée c'était de concevoir un feu vraiment visible, c'est assez utile, surtout en ville ou l'éclairage public rivalise à tel point avec le pouvoir éclairant d'un allumage de Solex que les automobilistes s'imaginent que l'on roule tous feux éteints.

D'après les mesures que j'ai faites, un allumage de Solex est à peine plus puissant (hors Flash, 6000, Micron, Ténor et période MBK) qu'une bonne dynamo de vélo.

Ce feu est basé sur un LM317 monté en régulateur de courant et fixé à 200 mA, or l'ampoule arrière d'un Solex (14 V 7W) est censée drainer 500 mA, ce montage consomme donc moins de courant, le résultat est que l'ampoule avant éclaire nettement mieux :mrgreen:
Et ça sans qu'elle ne grille pour autant, d'après mes deux mois d'essai en tous cas.

C'est vraiment un montage tout bête, le temps de mettre un schéma au propre, et je poste ça.
