Propose of a low cost integrating sphere

Abstract

This paper proposes the development of a low cost integrating sphere used for measuring flux characteristics and luminous spectrum lamps. The proposal provides the use of alternative materials as well the replacement of measuring high level equipment for more practical and common hardware accessories, providing a reduction in the cost of development. The objective is to minimize the cost of light sources assays, currently with a high cost, for research purposes, educational issues and the opportunity to use this alternative system for validation of new products, light bulbs and/or tubular daylighting devices for lighting indoors.
