Abstract
We developed the high-power LED beacon and investigated the applicability of composite materials for the light-weight design of LED beacon. By means of the application of composite materials, the vertical deformation could be reduced by 17% and the total weight of LED beacon 8.9 kg comparable to 20% light-weighting against aluminum beacon. In thermal radiation test, the maximum temperature of LED package was measured to $\small{63.5^{\circ}C}$ under ambient temperature ($\small{20^{\circ}C}$), which is acceptable considering both performance and lifespan of LED packages. In this study, the applicability of composite materials was demonstrated for light-weight design of high-power LED beacon.
