Abstract

To achieve reliability and optimal performance of LED Light sources a proper thermal management design is necessary. Furthermore, some concepts are shown in order to improve the thermal design. The authors have explored a physical phenomenon - the heat flux and temperature, LED lamp cooling system that operates on a heat pipe basis. The paper identifies the basic problem of the measuring heat flow. The general model of the street LED lamp that operates on a consistently and parallel connected thermal resistance basic is showed. The needs established methods of the calculation effective cooling system for outdoor lighting industrial facilities are analyzed. The dependence of the thermal resistance on the ratio of the physical processes is involved in optimizing the thermal regime, such as convection. The relevance of the impact of LED structure on its temperature field. Expressions are obtained for measuring the heat flux density and average integral heat flow. The bulk semiconductor luminaires developed with ribbed radiator, the calculation of which is produced by the known laws of convective heat transfer beam. For all its simplicity and clarity, such an approach is justified only in terms of engineering practice. Giving a fairly simple and feasible solutions for choosing or designing a radiator construction, such a model does not provide a clear understanding of how the convective pass streams, where air pockets occur, affects how the thermal conductivity of the materials used for the heat flow and spreading al.
