LED UV 365nm/1...3W


 Share

Recommended Posts

 As avea nevoie de un LED UV durabil -ideea e ca dupa 10.000 de ore de functionare sa nu-i scada luminozitatea sub 70% din valoarea initiala, altminteri e mai bun un tub fluorescent blacklight-functionare non-stop-ce se gaseste la noi la Zex...r e prea scump(3-400 lei), si nu-mi inspira prea multa incredere, chiar daca e Nichia, din pricina capsulei.

 Evident, daca exista la preturi rezonabile(50-60 lei) un asemenea LED de 1...3W...

 

 LED-urie UV in capsula cilindrica de acrilat de 5mm(China, no-name, fara nici un datasheet), desi alimentate corect(zic eu...) curent constant de 10mA, dupa cca. 4-5 luni raman cam cu 20-25 din lumina initiala sau decedeaza total, fara motiv( in afara de proasta lor calitate...).Ori poate gresesc total, astea n-or fi avand absolute limit rating in privinta curentului maxim de 20mA, ci poate doar de 7-8mA?!?

 

Ce-am gasit la ora actuala la noi, ar fi asta(rog sa nu se considere reclama):

Presupun ca la pretul acela, nu e nemaipomenit calitativ...

Multumesc de atentie.

In linkul pe care l-ai pus, poza sigur nu este cu Cree, ca ei nu folosesc capsula aia...

 

Uite ce am gasit imediat:

M-as duce pe LiteOn sau pe OptoSupply-ul de 4,5W

Mai erau si unele de la Osram, dar vad ca au disparut...
