Hi,
I'm new to the world of electronics and also to this forum. I have a number of questions about LED'S that I'd like answered if possible and after trawling the net for hours I decided to ask the experts (you people). I have no doubts that my questions are so basic your all probably gonna laugh :lol: but hey we all start somewhere
Right here we go.
1. I have an LED which I'd like to run at 9v. This is the technical bit: -
SOURCE MATERIAL:InGaN
EMITTING COLOUR:BLUE
LENS TYPE:WATER CLEAR
LUMINOUS INTENSITY-MCD:2000 TYPICAL/3000MAX
REVERSE VOLTAGE:5.0 V
DC FORWARD VOLTAGE:3.3V TYPICAL
DC FORWARD CURRENT:20~30mA
VIEWING ANGLE:± 10°
LEAD SOLDERING TEMP:260oC for 5 seconds
I'd like to get the brightest from the LED without putting to much pressure on it. What resistor would I use?
2. If you place one LED after the other would the resistor have to be changed or would you use 2.
3. What resistors would you use for a 12v set up.
Sorry if these are really simple questions but as I say I'm new (3 days into electronics) and could do with a little bit of help.
Thanks
