Our mathematical model is validated by an experiment we carried out for an LED placed in a cavity. According to the proposed design of experiments (24 factorial designs), we analyzed, by simulation modeling using COMSOL Multiphysics\u00ae, the influence of the different controllable parameters (the position A and width C of the openings, the inlet air velocity B, and the cavity height D) on the evolution of the junction temperature in order to optimize the thermal management of the proposed LED lamp. Using Minitab\u00ae manipulation software, a Pareto analysis and an analysis of variance (ANOVA) were carried out, and mathematical models were deduced to estimate the optimal junction temperature and the convective heat transfer coefficient of the proposed radiator and the surrounding air as a function of the controlled parameters. It was found that the position of the opening is the most influential factor on the junction temperature, with a contribution of 93.46%, followed by the factors velocity and width of the opening, with low contributions (3.22% and 1.24%). We also observe that the height of the cavity and the interactions (A \u00d7 C, A \u00d7 D, B \u00d7 C, B \u00d7 D, C \u00d7 D) have no significant influence on the junction temperature.<\/jats:p>","DOI":"10.3390\/sym17010058","type":"journal-article","created":{"date-parts":[[2025,1,1]],"date-time":"2025-01-01T13:37:51Z","timestamp":1735738671000},"page":"58","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Parametric Study by Design of Experiments of Thermal Management of a Light-Emitting Diode Dissipator in a Cavity"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9268-8663","authenticated-orcid":false,"given":"Zouhour","family":"Araoud","sequence":"first","affiliation":[{"name":"Universit\u00e9 de Monastir, ENIM, Laboratoire EMIR, LR20ES08, 5000 Monastir, Tunisia"}]},{"given":"Khaoula","family":"Ben Abdelmlek","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Monastir, IPEIM, Laboratoire EMIR, LR20ES08, 5000 Monastir, Tunisia"}]},{"given":"Kamel","family":"Charrada","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Monastir, IPEIM, Laboratoire EMIR, LR20ES08, 5000 Monastir, Tunisia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7582-5686","authenticated-orcid":false,"given":"Georges","family":"Zissis","sequence":"additional","affiliation":[{"name":"LAPLACE, Universit\u00e9 de Toulouse, CNRS, INPT, 31000 Toulouse, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1097-889X","authenticated-orcid":false,"given":"Laurent","family":"Canale","sequence":"additional","affiliation":[{"name":"LAPLACE, Universit\u00e9 de Toulouse, CNRS, INPT, 31000 Toulouse, France"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.2150\/jlve.31.11","article-title":"Lifetime estimation of high-power white LEDs","volume":"31","author":"Ishizaki","year":"2007","journal-title":"J.
