Abstract

The increasing market demand for LED illumination requires new design approaches for the replacement of conventional recessed luminaries. In this paper we present a series of glass reflectors covering a broad range of beam angles between 10° and 40°. The key feature of this development is the identical size of all reflectors making a modular set-up possible complying to a Zhaga-standardized LED module. The reflector dimensions are comparable to halogen MR16 lamps and allow an immediate use in existing downlight systems. Here, we present light technical measurements of these reflectors and compare the performance to already existing MR16 LED retrofit solutions.
