Not sure if your confusion about which component is which got resolved. Re-doing the math with these particular values gives the expected current for the LED: This site uses cookies. Both pt and led as with photodiodes are composed of pn junctions and should theoretically light up when forward biased to greater than their turn-on voltage.

To drive the LED, it has to datawheet above 1. The image sensors pick up IR! When a LED is forward biased, it emits light while the transistor switches and amplifies the colector-emitter current if the base-emitter junction is forward biased.

Posted by Dimitar Kovachev. The LED is blue, the phototransistor is clear. When forward-biased, the current through the photo-transistor is proportional to the amount of light. Sean Straw July 8, at Photo diodes have always confused me a bit. This leads us to our criteria — the current through a forward-biased LED is a constant; the current through a forward-biased PT varies with light.

IR LED and a photo-transistor – which is which? Kenneth Olsen January 4, at Under certain conditions, they will conduct electricity.
