This thesis focuses on LED (Light Emitting Diodes) encapsulation to change light patterns of LED light sources with integration of Photonic Crystals to LED packaging. This work involve the discussions of the basic principles of Photonic Crystals and LED at first, and then introduces LED to process and design and encapsulation technology, and then extends to Photonic Crystals characteristic and applications. By utilizing combinations of Photonic Crystals and LED, and research of 2-D Photonic Crystal structures of characteristic to change light patterns. We can replace the geometry lens structure to change light patterns of LED light sources, and to attain the objectives of the component’s thinness. Finally, this research utilizes the TracePro optics simulation software to establish LED element model. This tool is able to change LED lens parameters, types of lens and the distances between LED chip and lens. And, we can use geometrical lens to simulate 2-D Photonic Crystal structures to change light patterns of LED light sources using this methodology to analyze the performance characteristics. In addition, we can study the feasibility of substituting 2-D Photonic Crystals to the traditional geometrical lens.
