Le contr\u00f4leur photo\u00e9lectrique c\u00e2bl\u00e9\/bim\u00e9tallique<\/a> Il s'agit d'un dispositif de commande d'\u00e9clairage couramment utilis\u00e9, principalement pour contr\u00f4ler automatiquement l'\u00e9tat de commutation d'un circuit en fonction de l'intensit\u00e9 de la lumi\u00e8re ambiante.

  1. Principe de fonctionnement :<\/li>\n<\/ol>\n\n\n\n
      \n
    • Lame bim\u00e9tallique\u00a0: Le contr\u00f4leur photo\u00e9lectrique contient une lame bim\u00e9tallique. Cette lame est compos\u00e9e de deux m\u00e9taux ayant des coefficients de dilatation thermique diff\u00e9rents. Sous l\u2019effet de la chaleur, la diff\u00e9rence de dilatation entre les deux m\u00e9taux provoque la flexion de la lame bim\u00e9tallique.<\/li>\n\n\n\n
    • \u00c9l\u00e9ment photosensible\u00a0: Il s\u2019agit g\u00e9n\u00e9ralement d\u2019une photor\u00e9sistance ou d\u2019une photodiode, dont la r\u00e9sistance varie en fonction de l\u2019intensit\u00e9 lumineuse. En forte luminosit\u00e9 ambiante, sa r\u00e9sistance est faible\u00a0; en faible luminosit\u00e9 ambiante, elle est \u00e9lev\u00e9e.<\/li>\n\n\n\n
    • Fonctionnement du circuit\u00a0: Lorsque la luminosit\u00e9 ambiante est faible, la r\u00e9sistance de l\u2019\u00e9l\u00e9ment photosensible est \u00e9lev\u00e9e et la chaleur g\u00e9n\u00e9r\u00e9e par le courant traversant la lame bim\u00e9tallique est relativement faible. La lame bim\u00e9tallique reste alors inchang\u00e9e, maintenant le circuit ferm\u00e9. En revanche, lorsque la luminosit\u00e9 ambiante est forte, la r\u00e9sistance de l\u2019\u00e9l\u00e9ment photosensible diminue et le courant augmente. La lame bim\u00e9tallique se d\u00e9forme sous l\u2019effet de la chaleur, provoquant l\u2019ouverture du circuit.<\/li>\n<\/ul>\n\n\n\n

      1. Usage:<\/li>\n<\/ol>\n\n\n\n
          \n
        • Installation c\u00e2bl\u00e9e\u00a0: Ce contr\u00f4leur photo\u00e9lectrique est g\u00e9n\u00e9ralement \u00e9quip\u00e9 de bornes de c\u00e2blage standard et se raccorde facilement au circuit \u00e0 contr\u00f4ler par la lumi\u00e8re. Selon les besoins, il peut \u00eatre install\u00e9 \u00e0 proximit\u00e9 de la source lumineuse ou \u00e0 tout autre emplacement appropri\u00e9.<\/li>\n\n\n\n
        • Sc\u00e9narios d'application\u00a0: Largement utilis\u00e9 pour l'\u00e9clairage public, l'\u00e9clairage de jardin, les panneaux publicitaires et autres applications n\u00e9cessitant une commutation automatique en fonction de la luminosit\u00e9 ambiante. En param\u00e9trant judicieusement le seuil du contr\u00f4leur photo\u00e9lectrique, l'\u00e9clairage s'allume automatiquement lorsque la luminosit\u00e9 ambiante est inf\u00e9rieure \u00e0 un certain seuil et s'\u00e9teint automatiquement lorsqu'elle atteint un certain niveau. Ceci permet de r\u00e9aliser des \u00e9conomies d'\u00e9nergie et de prolonger la dur\u00e9e de vie du mat\u00e9riel.<\/li>\n<\/ul>\n\n\n\n
