Hi,
I want to build IR illuminator for my cctv camera and on ebay I have ordered this diodes:
**broken link removed**
but on that page I have spec for diodes:
Voltage: 1.5V~1.6V
Current: 20-25 mA
Peak(pulse): 700mA
Power: 200mW
If I good know, if I need 1.5v for this diode and if this diode using 25mA than power can`t be 200mW??!!! Somebody can tell me more about this? For me look like here is something bad...also, this is 10mm diode, why using only 25mA and some other IR 5mm diodes using 100mA?
Also, if this diode need 1.5v and if I have 12v power supply, can I use 8 diodes in series without resistor? I don`t need resistor in this case?
Thanks.
