The aim of this work is related to the development of efficient, low-cost active LED cooling systems for industrial applications in horticulture, poultry housings, dairy farms and others. Investigations and comparative analysis of different variants of LEDs' cooling by use of different types of water pipes were carried out to find an optimum thermal performance. Two types of water pipes — polyethylene...
Frequently the direct assessment of the LEDs' junction temperature as one of the main parameters to evaluate the extent of the thermal load is possible only under laboratory conditions. In this paper we present the development of a cheap and reliable experimental method to establish the junction temperature of high-brightness LED arrays under operating conditions. It is based on the insitu determination...
Investigations are connected with design and application of thermally and cost effective rigid LED strips. Standard FR 4 PCB is used for making rigid strip and LEDs are soldered on it. Special copper pins soldered underneath LEDs contribute to low thermal resistance between LEDs and heat sink - like when MCPCBs are used. Application of this type low cost rigid LED strips allows decreasing operations...
Investigation deals with LED's thermal management optimization in dependence of operating condition aided by application of infrared thermography. Thermal management calculations allow estimating temperature distribution on the LEDs, metal - core printed circuit boards (MCPCB) and heat sink but often real results may be different and experimental investigations are necessary. Good results are obtained...
