Dear all the professor council. My name is QA. Today, I am pleased to present an overview of my scientific research and training activities. Currently, I am a lecturer in the Department of Electrical Engineering at TDTU. In 2014, I earned a doctorate in electrical engineering from a university in Taiwan. Up to now, I have worked at TDTU for 9 years. When it comes to determining a research direction in my research career, white LED development for sustainable lighting solutions has caught my attention. 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. The key factors determining the final performance of white LEDs include mainly concerns optics, thermal science, materials, mechanics, electronics, packaging processes, and equipment. In general, materials, processes and equipment are the basis for the development of white LED packaging. It is the advancements in these three features that make the high-quality white LEDs realizable. Based on the manufacturer's requirements, we have 5 specific research goals to achieve, including the luminosity, color uniformity, color rendering index, the distribution uniformity of the light output, and the production cost. The focus of our research is on the common WLED's packaging structure. This particular WLED package utilizes the blue-light emitting chip and yellow phosphor to produce white light. In the research of WLED packaging development, we have published 4 articles and one patent. Most of them are in Q2 and Q3. The first article is a freeform lens design for LED fishing lamps. In this paper, we compared the power and flux intensity of two lighting systems: LED and HID lamps. The comparison between the two lighting systems is presented on different projected areas: on the water surface and on the fishing boat's deck. The novel approach in this paper in 2016 is the idea of multi-segment design. At the time of publication, the approach in our second paper was a new method, a method of increasing the lumen output of LEDs by using green phosphor. Specifically, the luminous flux was improved by 25% and 40% for the conformal and in-cup structures, respectively. The CCT deviation also decreased significantly, However, CRI showed decrease with increasing green phosphor amount, 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. Applying the Mie scattering theory, we explained the relationship between the emitted luminous flux and the attenuation coefficient 453 nm and 555 nm wavelengths. However, even within the recommended concentration range, the emitted luminous flux and color rendering index are still inversely related. As the color rendering index increases, the luminous flux tends to decrease. Hence, it is essential to develop a new phosphor-coating structure that excels in both brightness and color quality. In 2019, we proposed the new structures adopting the remote-phosphor concepts. Specifically, there were two dual-layer structures and a triple-layer structure demonstrated. The triple-layer 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, yet lower than that of the YR structure. The color uniformity of this triple-layer structure is also the highest. Thus, the first 3 goals have been achieved with the presented phosphor-coating structures. Meanwhile, the other two objectives can be accomplished with my freeform lens design. My freeform lens design was granted a patent in 2021. The design idea comes from two types of commercial lenses. The design goal is to overcome the disadvantages of those two types of lenses. Multi-segment design method based on Snell's law was applied for the design; and here is a simulation of the light path. This is a simulation of the lens surface design. The lens was then attached to the LED for experiments. 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. In 2018, I started to implement a big project in Binh Thuan province. This project applies new LED lighting technology on 5 ships. This project has brought significant benefits and impacts. This is a big project, bringing a lot of scientific and training results. After the project, more than 60 ships switched to LED lighting technology. Regarding my lecturing statistics, for the past 9 years, I have met the standard teaching hours and even exceeded that number. I am in charge of teaching 6 courses in electrical engineering. I compiled 2 COURSE SYLLABUSES in the master's program. and teaches this subject in the doctoral program. I have supervised 2 Master's students. And I have completed supervising a PhD student. Scientific research with students is an important job, and I participated in these 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 with regard to practical requirements. This is a summary of my research outcomes, meeting the prescribed standards for the associate professor title. Thanks to all the professor council.
