IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

Sunnyvale, CA, October 8, 2009 — The new infrared Platinum Stack DRAGON from OSRAM Opto Semiconductors provides high optical output from a small surface area, creating an ideal high-radiance solution ...

144 LEDs total. Three sets of 48 in series connected in parallel. My problem is I don't know what value to use for R1. I'm thinking 600 ohm, but I really don't know how to calculate this. I'm making ...

Ams Osram has introduced its new IR:6 thin-film infrared (IR) LED chip technology that increases illumination and efficiency in security and biometric applications. The new devices deliver 35% higher ...

OPTEK’s comprehensive range of miniature smt IR LEDs and phototransistors is now fully available from Pacer. OP2xx IR LEDs include high power, narrow beam and wide beam versions. OP5xx silicon ...

OK, I don't know electronics at all. I need to convert the 12 or 5v line from the power supply to power a 3v LED. So, if V = IR, I need to know the current ...
