Efectul Joule este cea mai proasta metoda de a transforma electricitatea in lumina. De fapt in caldura. Lumina este un efect secundar.<br \/>\nCele &#8220;economice&#8221; nu mi-au inspirat niciodata prea multa incredere. Inferioare filamentului in ceea ce priveste cantitatea de lumina. Pana sa dea lumina maxima, trec secunde\/minute bune, suficient cat sa iti scoti ochii.<br \/>\nNeonul (se cheama tub cu descarcare in gaz. de unde obsesia asta cu neon? neonul da lumina rosie. nu e niciun atom de neon acolo, sunt vapori de mercur !!!) are nisa lui incontestabila.<br \/>\nLED-ul a avut un inceput timid, dar cred ca acum s-a maturizat suficient incat sa constituie principala alegere. Dioda electroluminiscenta (Light Emitting Diode) este modalitatea cea mai eficienta de a transforma electricitatea in lumina. Deci lumina multa si consum mic. Si (aproape) fara caldura.<br \/>\nDe aceea mi-am trecut toata casa pe iluminat LED. Ca sa ai un termen de comparatie real, pentru a obtine lumina unui bec cu filament de 100W, un bec cu LED consuma cam de 7-8 ori mai putin. Deci 12-14W. Becurile cu LED nu sunt foarte raspandite acum si costa destul de mult. Dar cresc vertiginos.<br \/>\nInsa\u00a0eu am mers un pas mai departe si am inceput sa inlocuiesc becurile cu LED cu panouri LED.
