Cofinancing of the AI-TWILIGHT project Co-financing of the AI-TWILIGHT project by the Hungarian government through the 2019-213-NEMZ_ECSEL-2021-00008 grant of the National Research, Development and Innovation Fund is also acknowledged. Part of this work was also supported by the K_128315 (aTKA) project of the Hungarian National Research, Development and Innovation Fund. 0 false 2026-01-01T16:47:27.540+0000 2023-09-19T19:50:58.872+0000 2023-03-13T15:24:53.721+0000 true 10087260 Szatmári Erika /api/admin/10087260 Admin false 2023-09-19T19:50:59.197+0000 2023-09-19T19:50:59.197+0000 2023-05-27T17:27:28.764+0000 true 521 Szuper Admin /api/admin/521 Admin true true false true 25 25 /api/publicationtype/25 PublicationType 2 true 25 BookChapter true 10000312 Conference paper true 25 25 /api/publicationtype/25 PublicationType 2 true 25 BookChapter /api/subtype/10000312 Konferenciaközlemény SubType 228 true 10000312 true 1 /api/category/1 Category true 1 Hegedus, Janos The effect of dimming frequency on the aging of power LEDs 158 158 5 2022 The possibility of easy, PWM-based dimming of LEDs is a big advantage compared to former light sources, but at the same time, it may also result in additional aging mechanisms compared to continuous DC operation. Due to the different coefficients of the thermal expansion of each structural layer, temperature cycling can degrade the main heat conduction path of the LED chips. In this paper, we examine, how the different dimming frequencies affect the aging of LEDs, and to what extent they impair the thermal conductivity of structural layers belonging to different thermal time constants. true false 2023 true true true true true false NONE 2026-01-01 false 2 1 2 2 0 0 2 2 0 2 2 2 2 2 0 0 2 2 2 2 0 2 2 Folyóiratcikk Journal Article 24 0 Könyvrészlet Chapter in Book 25 2
