Static and Dynamic Analysis for High Power Light Emitting Diode Street Light Fixtures under Wind Load
As a newly lighting source, high power white light emitting diodes (LEDs) have many excellent performances and begin to be widely used. The LED street light fixture is one of the most typical and popular applications, which is studied and developed worldwide. However, those studies mainly focused on its light efficiency, light pattern, color temperature, and so on, few concentrated on the reliability of the LED street lighting, especially structure strength analysis and evaluation. In this paper, an 112 watt LED street light fixture is analyzed under wind load by simulations. Static and dynamic analysis under wind load are conducted, which contains static wind load analysis, modal analysis, harmonic response analysis, and transient dynamic analysis. Numerical simulation results show that it is necessary to make structure strength analysis for the design of LED street light fixtures.
