Dans une ampoule \u00e0 incandescence classique, une grande partie de la puissance est dissip\u00e9e en chaleur et est donc inutile \u00e0 l’\u00e9clairage de la pi\u00e8ce. Le proc\u00e9d\u00e9 d\u00e9velopp\u00e9 permet de r\u00e9fl\u00e9chir une partie de la chaleur dissip\u00e9e vers le filament o\u00f9 une fraction sera transform\u00e9e en lumi\u00e8re, augmentant ainsi le rendement de l’ampoule.<\/p>\n
La version am\u00e9lior\u00e9e permet de r\u00e9duire de 30% la consommation par rapport \u00e0 une ampoule classique, ce qui est remarquable, mais assez faible quand on sait qu’une ampoule \u00e9conomique r\u00e9duit la consommation de 75-80%. Leur dur\u00e9e de vie sera \u00e9galement 3 fois plus grande, l\u00e0 aussi c’est une belle performance mais les ampoules \u00e9conomiques ont une dur\u00e9e de vie 10 \u00e0 20 fois plus grande qu’une ampoule classique… Tout cela sera-t-il suffisant ? J’ai bien peur que cette brillante invention ne parvienne pas \u00e0 sauver l’ampoule incandescente !<\/p>\n
Les premi\u00e8res ampoules commercialis\u00e9es de ce type seront les \u00ab\u00a0Philips Lighting\u2019s Halogena Energy Savers\u00a0\u00bb, Philips promet que pour une consommation de 70W, les ampoules fourniront un \u00e9clairage \u00e9quivalent \u00e0 une ampoule de 100W (pile 30%, sont forts chez Philips). Au moins, pour le moment, \u00e7a va permettre une alternative pour ceux qui souhaitent \u00e9viter les ampoules basse consommation.<\/p>\n
Deposition Science pr\u00e9tend pouvoir diminuer la consommation de 50% avec leurs derni\u00e8res am\u00e9liorations en laboratoire et attendent qu’un industriel soit pr\u00eat \u00e0 tester les toutes derni\u00e8res avanc\u00e9es…<\/p>\n
