    Hello,

    I was just wondering if anyone would be able to explain to me ( or know of
    any website that can explain to me) how self flashing LEDs work and how they
    should be analyzed in a DC circuit. Are they to be analyzed in the same
    manner as regular LEDs?

    Thank you,

    Mike

    ** There is an electronic switching circuit on the chip with the LED.

    You have to read the maker's data to see what DC voltage supply is needed
    and what the current draw & flash rate will be.


    ** No.

  3. Flashing LED's have a built in circuit powered from a fixed voltage
    rail.
    So from an analysis point of view it is totally different to a normal
    LED.
    given supply voltage) when the LED is on, and a much smaller quiescent
    current when the LED is off.
