Abstract

The present invention, in one aspect, provides light emitting devices comprising LEDs, the light emitting devices, in some embodiments, having a simplified architecture for controlling the color of emitted light.

Description

[0001] Cross references to related applications [0002] This application claims the priority of the U.S. patent application filed on February 16, 2010, with application number 12 / 706,370, and the title of the invention "Color Control of Light Emitting Devices And Applications Thereof" , And incorporate its entire contents by reference. Technical field [0003] The present invention relates to light emitting devices, and specifically to solid state light emitting devices. Background technique [0004] A light emitting diode (LED) is a solid-state device that converts electrical energy into light, and usually includes one or more active layers of semiconductor material sandwiched between anti-doped layers. When a forward bias is applied across the doped layer, holes and electrons are injected into the active layer, where they recombine to emit light. The light is emitted from the active layer and is led out into the surrounding environment from all transparent surfaces of the LED. ...
