“…In addition, research has been proposed on the uniformity of LED desk lamp illumination and improvement methods (Lin & Chen, 2023). Given the problem of heat dissipation in LED desk lamps, Chu et al (2015) adopted the design of 12 cooling holes on both sides of the heat sink to produce a chimney effect through natural convection to reduce the temperature.…”

Technology development has effectively guided the design and development of light-emitting diode (LED) desk lamps, and the design and development of desk lamps are closely related to users. However, studies on user satisfaction when using desk lamps are still under explored. To this end, this paper proposes a satisfaction evaluation method that combines the fuzzy analytic hierarchy process (FAHP) and fuzzy comprehensive evaluation (FCE). This research results could provide an effective theoretical and practical reference for the experience design of LED desk lamps to improve and meet users' needs, thereby potentially improving the design of LED desk lamps for better customer satisfaction.

“…One of the reasons may be that LED desk lamps, as lighting products, emphasize more on functionality and technology. Therefore, the research mainly focuses on colour temperature Chen & Ge, 2017), heat dissipation (Chu et al, 2015;Ekpu et al, 2022), and anti-glare (Ye et al, 2020;Lai et al, 2014) and other technical aspects. This technology-oriented research mainly focuses on the performance and functions of LED desk lamps and pays less attention to the user's feelings and experiences.…”

LED desk lamps are widely used in modern life as one of the lighting products. However, only a few studies focus on the user experience (UX) of LED desk lamps. Therefore, this study adopts the importance-performance analysis (IPA) model, with the aim of exploring strategies to enhance the UX of LED desk lamps. We evaluated the key factors of UX based on the importance and actual performance of LED desk lamps for users. By analyzing the results, we proposed strategies to improve LED desk lamps, thereby potentially improving the consumer experience and market competitiveness of LED desk lamps.

“…Selain itu, komponen penyusun TEC yang penting adalah heatsink luar. Bagian ini merupakan dudukan untuk meletakkan elemen peltier dan berfungsi dalam mempercepat proses pelepasan kalor pada sisi panas peltier menuju lingkungan (Chu, Chang & Huang, 2015;Khurshid, Silaipillayarputhur & Mughanam, 2018;Srikanth & Ramesh, 2017;Widianto et al, 2014). Heatsink harus mampu melepas kalor dengan cepat pada sisi panas elemen peltier, agar didapatkan performa TEC yang optimal.…”

Alat transportasi ikan segar (ALTIS) adalah sarana pendingin yang dapat mempertahankan mutu ikan segar. ALTIS umumnya digunakan oleh pedagang kelliling dalam transportasi dan distribusi produknya. Komponen yang menentukan kinerja pendingin adalah heatsink dan dudukan peltier. Kedua bagian ini berfungsi dalam transfer panas kotak penyimpanan ikan menuju udara. Namun, biaya produksi dan harga material kedua komponen tersebut cukup tinggi. Penelitian ini bertujuan untuk modifikasi spesifikasi heatsink dan dudukan peltier, agar mendapatkan efisiensi biaya pembuatannya. Heatsink dibuat dari 3 mm plat tembaga dengan 18 sirip aluminium yang memiliki ketinggian 10 mm dan ketebalan 1 mm. Sementara itu, dudukan peltier juga dibuat dari alumunium dengan ketebalan bervariasi (4, 5, 6, dan 10 mm). Performa kedua bagian ini diuji dengan variabel suhu heatsink dalam, heatsink luar, dan ruang penyimpanan ikan, setiap 5 menit selama 95 menit. Hasil pengujian menunjukkan bahwa suhu ruang penyimpanan ikan menggunakan heatsink baru (17,8°C) lebih rendah dari heatsink sebelumnya (18,3°C). Desain heatsink yang baru ini dapat mengurangi biaya pembuatan sebesar Rp. 807.000,00. Dudukan elemen peltier dengan alumunium setebal 4 mm dapat mempercepat proses perpindahan panas dari ruang penyimpanan ikan menuju peltier. Modifikasi ini dapat diaplikasikan untuk menurunkan biaya dan meningkatkan performa ALTIS.ABSTRACTRefrigerated Fresh Fish Container (ALTIS) is a cooler equipment to maintain the quality of fresh fish. ALTIS is usually used by the itinerant fish traders to preserve their products in transportation and distribution. The components that determine the cooler performance are the heatsinks and the Peltier base plate. These components are responsible for transferring the heat from the fish container to the air. However, the production costs and material price for both components are expensive. This study aimed to reduce production costs by modifying the heatsink and Peltier base plate design specifications. The heatsink was made from 3 mm thickness copper and aluminum fins. The aluminum fins were 18 pieces in total, with 1.6 mm thickness and 10 mm height. Meanwhile, the Peltier base plate was also made from aluminum with varied thicknesses (4, 5, 6, and 10 mm). The performance of both parts was evaluated by temperature measurement in the inner heatsink, outer heatsink, and box container for every 5 minutes in 95 minutes. The results showed that the refrigerated container box temperature with the new heatsink (17.8°C) was lower than the existing heatsink (18.3°C). Moreover, the new heatsink design may reduce the production costs by Rp. 807,000.00. Furthermore, the Peltier base plate with a 4 mm thickness could accelerate the heat-dissipating of Peltier. Thus, the modification can be applied for ALTIS production with lower cost and better performance.
