Dear all professor council. My name is QA. Today, I am pleasured to present the overview of my scientific research and training activities. Currently, I am a lecturer in the department of electrical engineering, TDTU. In 2014, I graduated with a doctorate in electrical engineering in Taiwan, and until now, I have worked at TDTU for 9 years. Choosing a research direction is important, because it follows the scientist throughout his or her life. There are 3 research directions related to white LED packaging: Freeform lens; Light scattering material and Lighting Technology for a Sustainable Future. White LED packaging is a complicated technology. It mainly concerns optics, thermal science, materials, mechanics, electronics, packaging processes, and equipment. These key factors determine the final performance of white LEDs. Generally, materials, processes and equipment are the basis for the development of white LED packaging. It is the advanced materials, processes and equipment that make the high quality white LEDs realizable. Based on the manufacturer's requirements, we have 5 specific research goals to achieve. Specifically, we focus on two issues. blue light passes through yellow phosphor particle. This is the common phosphor structure. There are 4 typical articles and one patent. Most of them are in Q2 and Q3. The first article is a freeform lens design for LED fishing lamps. We can compare the power of the lighting system and the flux emitted. On the water surface and On the deck of fishing boat. The idea of multi-segment design is the new method in 2016. This was a new method at the time of publication, a method of increasing the lumen output of LEDs by using green phosphor. Specifically, the luminous flux can be increased by 25% and 40% respectively for the two structures. and CCT deviation decreased significantly, However, CRI tends to decrease, which is the disadvantage of this method. To improve the color rendering index, we proposed the solution to use red phosphor Y2O3: Eu3+ for the first time in 2017. Based on the research results, it can be seen that CRI increased significantly in all types of lamps. Based on the Mie scattering theory, we explain in detail the relationship between the emitted luminous flux and the attenuation coefficient at 453 nm band 555 nm. However, even in the optimal concentration range proposed above, the emitted luminous flux and color rendering index tend to be opposite, the luminous flux tends to decrease as the color rendering index increases. Therefore, the development of a new phosphor coating structure that excels in brightness and color quality is essential. In 2019, three new structures were proposed. The YRG structure has a higher luminous flux than other structures. The CRI of YRG is also higher than that of the YG and Y structures. Uniform color is also best. Thus, the first 3 goals have been achieved. I have a patent on freeform lens design. The design idea comes from two types of commercial lenses. The design goal is to improve the disadvantages of those two types of lenses. Multi-segment design method based on Snell's law. and here is a simulation of the light path. This is a simulation of the lens surface design. When attaching the design lens to the LED light. Here is a comparison table of luminous efficiency with two types of lenses. Here is a comparison table of illuminance uniformity with the two lens types. This technology can be applied to many different types of LED lights. and I am developing research direction 3; lighting technology in the fields; towards lighting technology for a sustainable future, according to the United Nations' goal number 7. I implemented a large project in Binh Thuan province. This project applies lighting technology on 5 ships. This project has brought significant benefits and impacts. After the project, more than 60 ships switched to LED lighting technology. For the past 9 years, I have completed and exceeded my teaching hours. I teach 6 courses in electrical engineering. I compiled 2 COURSE SYLLABUS in the master's program. and teaches this subject in the doctoral program. I have supervised 2 master students. And I have completed supervising a PhD student. Scientific research with students is an important job, including 4 work contents. Participate in writing self-assessment reports of undergraduate and master's training programs in Electrical Engineering. I have won national and international awards. Participate in project evaluation panel on lighting engineering. Participate in the review of reference books for electrical engineering students. Participate in evaluating dissertations of electrical engineering students. Participate in domestic and international conferences. In the near future, I will continue my training and research work according to practical requirements. This is a summary of research results, meeting the prescribed standards for the title of associate professor. Thank for all professor council.
