A multi-functional design approach and proposed figure of merits for solid state lighting systems

Abstract

Optimisation of a heat sink in LED system. Developing figure of merits (FOM) for designers and researchers to find the most optimal solution accounting for critical metrics of size, weight, cost, and performance. Thermal, electrical, and optical experimental results of various commercial A-line LED lamps are investigated and a number of FOMs are proposed based on the performance, size, and weight. Proposed FOM aim to evaluate different aspects by combining a number of performance metrics. Results show one can combine and analyze multi-purpose design parameters for thermal, electrical and optical performances and manufacturing for engineers and consumers.
