Proposal of a Hybrid System for Solar and Photovoltaic for Lighting Low Cost

Abstract

This work consists of the study and development of a hybrid lighting system that uses Led as artificial light source and sunlight as a natural source. Starts with a survey of this technology being developed in the tubular lighting system as well as the search for its replacement by alternative materials as a way to fund the project, uniting quality and reduced cost. With the definition of constructive elements, proceeds to the beginning of project design and development of control to maintain brightness in the environment system. Using as guidance the Brazilian Standards, which govern the methods of measuring brightness, as well as the procedure for creating models scaled tools. Finally presents the tests and their results, demonstrating the possibility of developing a hybrid lighting system at low cost.

Study on the Potential Use of Electrochromic Materials for Solar Energy Harvest in Brazil Market

“…These products are distributed by various countries, including Brazil [19] . However, in Brazil, there are few places with this technology installed, because it is a high cost product for the Brazilian economic reality [20] . The functioning of this type of lighting system is composed of three fundamental elements, as can be seen in Fig.…”

“…This is the conductor, it has highly reflective inner lining (can reach up to 99.7%), he is responsible for transporting the natural light reaching the dome and submit the same for reflection to the diffuser lens (indoor), the lens in turn causes the dispersion of incoming rays, improving distribution and illuminating the environment. [20] . Fig.…”

“…The domes are designed to enhance the capture and direction of sunlight, enjoying the sunlight to low angle, thus increasing the light gathering time [20] .…”

“…9. Reflexive ducts [20] The product manufactured by the company Solar Espacio is made of aluminum and receive a surface treatment on highly reflective silver with PVD technology -Silver-Plus Alanod, causing the reflective factor of the system reaches 98% [21] .…”

“…The diffuser lens is the last element of the tubular lighting system, it serves to diffuse the light received from the reflective tube and illuminate the interior with quality of the environment, in addition, it also contributes to the thermal insulation and acoustic design [20] . This type of lens is made of polymeric material (acrylic) on either manufacturers that may be developed in various shapes, adapting this aesthetic modeling environment, as can be seen in Fig.…”
