LED light-emitting component based on photonic crystal reflector

The invention belongs to the field of photonic crystal reflection, and particularly relates to an LED light-emitting component based on a photonic crystal reflector. The LED light-emitting component based on the photonic crystal reflector comprises a one-dimensional photonic crystal reflector and an LED structure, wherein the one-dimensional photonic crystal reflector is connected with a substrate of the LED structure, the one-dimensional photonic crystal reflector is any of a green light one-dimensional photonic crystal reflector, a blue light one-dimensional photonic crystal reflector and a purple light one-dimensional photonic crystal reflector, the green light one-dimensional photonic crystal reflector can efficiently reflect green light in the full angle, the blue light one-dimensional photonic crystal reflector can efficiently reflect blue light in the full angle, and the purple light one-dimensional photonic crystal reflector can efficiently reflect purple light with full angle. With the component, light emitted by an LED structure can be utilized to a larger extent.
