Abstract

In this research, the influence of scattering enhancement particle TiO 2, SiO 2 , CaF 2 , and CaCO3 concentration, which adds to the YAG:Ce phosphor compounding, on the luminous efficiency of multichip white LEDs (MCW-LEDs) was proposed and analyzed. Firstly, the physical model of MCW-LEDs is simulated and demonstrated by using commercial LightTools 8.4 program. After that, the effect of scattering enhancement particles on the luminous efficiency is calculated and analyzed. Then, the luminous output of the 8500K W-LEDs are demonstrated convincingly by the Monte Carlo simulation and the Mie-scattering theory. The simulation results indicated that the highest luminous output could be accomplished with CaCO 3 particles. The results and discussion provided a prospective approach for higher-quality manufacturing W-LEDs in the near future.

TiO2、SiO2、CaF2和CaCO3：颗粒浓度对共形几何MCW LED发光效率的影响

在本研究中，提出并分析了添加到YAG:Ce荧光粉复合物中的散射增强颗粒TiO2、SiO2、CaF2和CaCO3浓度对多芯片白光LED（MCW LED）发光效率的影响。首先，使用商业LightTools8.4程序对MCW LED的物理模型进行了仿真和演示。然后，计算并分析了散射增强粒子对发光效率的影响。然后，通过蒙特卡罗模拟和Mie散射理论，令人信服地证明了8500K W-LED的发光输出。模拟结果表明，CaCO3颗粒可以实现最高的发光输出。这些结果和讨论为在不久的将来制造更高质量的W-LED提供了一种前瞻性的方法。

期刊介绍： International Journal of Automation and Smart Technology (AUSMT) is a peer-reviewed, open-access journal devoted to publishing research papers in the fields of automation and smart technology. Currently, the journal is abstracted in Scopus, INSPEC and DOAJ (Directory of Open Access Journals). The research areas of the journal include but are not limited to the fields of mechatronics, automation, ambient Intelligence, sensor networks, human-computer interfaces, and robotics. These technologies should be developed with the major purpose to increase the quality of life as well as to work towards environmental, economic and social sustainability for future generations. AUSMT endeavors to provide a worldwide forum for the dynamic exchange of ideas and findings from research of different disciplines from around the world. Also, AUSMT actively seeks to encourage interaction and cooperation between academia and industry along the fields of automation and smart technology. For the aforementioned purposes, AUSMT maps out 5 areas of interests. Each of them represents a pillar for better future life: - Intelligent Automation Technology. - Ambient Intelligence, Context Awareness, and Sensor Networks. - Human-Computer Interface. - Optomechatronic Modules and Systems. - Robotics, Intelligent Devices and Systems.
