Linear lamp simulations for near field reflections

Abstract

Linear lamps (fluorescent or LED) represent an option for specific applications. Fluorescent lamps maintained some important advantages, even if energy efficiency is in the discussion. For near-field simulations – coves, and luminaires – the usual mathematical representation is not sufficient. An IES file is valid for normal interior lighting, not for near-field, and the traditional theory doesn’t have any approach. The paper proposes a method to solve these limitations, and specific MATLAB solutions are presented. Measurements in the field, for the test problem, validate the method.
