Price-performance ratio analysis of advanced LED lighting applications

In the first part, this paper aims to analyze the optical and electronic performance of advanced drivers for LED lighting applications, taking into account the financial aspects. Consequently, for two price classes (low- and high-cost), we investigate the power conversion efficiency, their grid impact, lighting characteristics, and finally the cost-benefit ratio. Experimental measurements on physical prototypes validate the simulations performed with real supplying conditions. The final part of the paper explains some optimization steps for price-performance ratio according to a multicriteria matrix or to the main criteria established by the beneficiary. The study should be a useful decision making tool for both the scientific community and the contracting authorities.
