A time period you’ll very likely see normally when dealing with LEDs is the forward voltage. It's a range that will help you With all the voltage your circuit demands to supply to LEDs.
便於聚焦，因發光體積細小，而易於以透鏡等方式達致所需集散程度，藉改變其封裝外形，其發光角度由大角度散射至細角度聚焦都可以達成。
Yet another way to mild up an LED is to simply link it to a coin mobile battery! Because the coin cell are not able to supply more than enough latest to damage the LED, you'll be able to link them straight alongside one another!
