Behaviour of InGaN LEDs in Parallel Circuits

Some year s ago, the color range of Light Emitting Diodes ( L EDs) on the market was limited to the red to green spectrum. Then, blue LEDs were developed and introduced into the market . These blue devices made it possible to build so called “ single- chip white ” LEDs, using a yellow converter material in combination with a blue die. Most of the blue and white LEDs use Indium Gallium Nitrite (InGaN) as an epitaxial layer.
