dc.description.abstract | In the application of LED luminaire in industrial lighting, especially in large-scale industrial plants and warehouses and workplaces with high ceilings, LED high bay luminaire are a commonly used type of LED luminaire. Most of the surrounding environment where such luminaire are installed is not well ventilated. In summer, the ambient temperature is high, which leads to difficult heat dissipation. In order to adapt to this harsher environment, the heat dissipation of LED high bay luminaire must be examined with higher standards that are more in line with the operating environment. This paper considers the use of a UL1598 safety standard certification specification called "non-IC type embedded ceiling-mounted luminaire abnormal temperature test box" to examine the heat dissipation performance of the ceiling light, we simulate and study the relevant LED high bay luminaire in this test box Heat dissipation factors, and further implement the trial production of the test box and the actual lamp verification.
First of all, this thesis will conduct a temperature simulation study on LED high bay luminaire that can meet the test specifications required in the UL1598 certification, by analyzing the material of the lamp, the size of the radiating fin, and the placement of the mobile heat source. , To find the simulation condition parameters that can achieve the best heat dissipation effect. The simulation research results show that the condition parameters adjusted after research and analysis can effectively improve the heat dissipation capacity. Then, the trial production of the physical test box and the actual lamp verification were carried out. After the actual experimental test, it was confirmed that the experimental test result was quite close to the simulation result, and the overall temperature of the lamp was within the specification. This can not only prolong the life of the lamp, and be relatively safe to use, but also achieve the purpose of energy saving and carbon reduction. | en_US |
