Temperature Analysis of Obstacle Lighting Lamp Working under Various Ambient Conditions: Theoretical and Practical Experiments.

Featured Application: Featured Application: The results of the experimental tests were carried out in the laboratory of BSSTC.PL Sp. z o.o. and OLATECH DR INZ. Andrzej Błachowicz using an obstacle lighting lamp that is currently in production. The developed simulation model, which has been verified experimentally, was used to determine the influence of changes in meteorological parameters on the temperature distributions on the surface of the lamp. It will be used in the future to optimize the geometry of the heat sink used in the lamp in terms of electricity consumption and thermal resistance. It is planned to extend the application of the lamp under difficult climatic conditions. The article presents the results of experimental and theoretical works aimed at determining the distribution of heat emitted by an obstacle lighting lamp. These kind of lamps are commonly applied as a warning for air traffic vehicles. There is a need for lighting devices with various intensities, whose application depends on the location and operating conditions. The overall aim of the author's work is to develop a computer model that would enable us to conduct research aimed at determining the optimal parameters of lamp operation without the need to build many physical models. Measurements of heat emitted by a currently manufactured lamp were made, and based on these, a numerical model of the lamp operating under laboratory conditions was developed. The considered lamp has two heat sources, one of which is light-emitting diodes (LEDs), while the other heat source consists of stabilizers and other elements of the lamp power supply system. After positive experimental verification of the numerical model, theoretical analyses of heat emission under various meteorological conditions were carried out, while the values of ambient temperature and airflow velocity were changed; then, the influence of these parameters on the temperature distribution on the surface of the lamp was determined.
