Bi-Color LED<\/strong><\/p>\n

Bi-color LEDs contain two different LED emitters in one case. There are two types of these. One type consists of two dies connected to the same two leads antiparallel to each other. Current flow in one direction emits one color, and current in the opposite direction emits the other color. The other type consists of two dies with separate leads for both dies and another lead for common anode or cathode so that they can be controlled independently. The most common bi-color combination is red\/traditional green, however, other available combinations include amber\/traditional green, red\/pure green, red\/blue, and blue\/pure green.<\/p>\n
