Bypass verificare lampa videoproiector

Recommended Posts

Guest yoben2q2q

Salutare elforum! am gasit prin garaj un vechi proiect despre cre am mai discutat . un videoproiector la care vreau sa inlocuiesc lampa originala cu un led . ideea e ca nu stiu ce si cum trebuie legat la optocuplor ca videoproiector sa detecteze ca are instalata lampa , chiar daca nu are . post-243047-0-44600700-1455391463_thumb.jpg in cate stiu sunt cele 3 din stanga jos , negre .

 Optocupla are urmatorii pini

1-anod
2-catod
3-emitor
4-colector
Doua din ele sunt indreptate cu pinii 1,2 spre mufa de intrare (spre circuitul format doar din mufa de intrare si 2 rezistori - pe placa scrie ca ar fi circuitul secondar)  iar a3a invers

http://www.datasheetarchive.com/dlmain/Datasheets-10/DSA-189394.pdf aici e datasheet gasit pe internet , nu am gasit exact modelul , singura diferenta fata de ce am eu e ca nu are al1 dupa 2581 dar din ce am citit pe internet sunt la fel
