Design and Development of task light simulator for Quality Lighting Factor and Simulation of LED tube- based Illumination system for Laboratory

Abstract

Daylight is only the natural light available surrounding us which is mostly useful in outdoor use. Artificial lighting is used to a greater extent in the world for a variety of indoor as well as outdoor applications. The fundamental requirement of light is to see the objects in a dark time. Nowadays powerful light sources are developed to fulfill the fundamental requirement and the quality illumination. Quality lighting provides uniform distribution in space, good color rendering, and adequate light. The requirement of every task is different and the quality of lighting depends on a number of factors, so there must be a database available that will provide recommended values for a given task. Though there are several simulation software available for analysis of illumination, they are able to provide only information of illumination pattern based on user inputs. There is a need for a user-friendly GUI (Graphical User Interface) which provides necessary parameter values for good lighting design and spectral power distribution of different LED (Light Emitting Diode) sources. The main aim of this work is to model and simulation of spectral characteristics of monochromatic and white LED. Develop a MATLAB-based GUI to select recommended values for different tasks according to Illuminating Engineering Society (IES) standards which helps lighting designers for selection of proper light sources. Uniform illumination is obtained and energy is saved by the integration of daylight with artificial light. A case study of LED tube-based glare-free illumination for the laboratory is also reported.
