Light emitting diode with two alternative mounting sides for mounting on circuit board

摘要

An exemplary light-emitting diode (LED) includes a substrate, a first electrode and a second electrode sandwiching the substrate therebetween, an LED chip electrically connected to the first electrode and the second electrode, a reflector located on the first electrode and the second electrode and surrounding the LED chip, and a first retaining wall mounted on an edge of the first electrode and a second retaining wall mounted on an edge of the second electrode. The first retaining wall and the second retaining wall are made of conductive material. The first retaining wall and the second retaining wall are at a same side of the LED. Outer surfaces of the first retaining wall and the second retaining wall are exposed out of the reflector.
