Proposta de um sistema alternativo para captação da luz solar de baixo custo para inserção no mercado Brasileiro

This paper presents a study on the potential use of fixed collectors consist of prismatic lenses that capture sunlight for indoor lighting. The proposed research is to develop an alternative system to capture sunlight, aimed at lighting environments with natural light directly, maintaining thermal comfort without cost functional, using a source of clean and inexhaustible energy. Currently the technology to capture the natural light is not developed in Brazil, but is already exploited in other countries so quite efficiently reaching present yield greater than 90% transmission of natural light due to its high quality finish. Nationally the application of this technology is in quite small considering the high cost of implementation for point light added to the import taxes can reach US$ 1,500.00. With the focus in the popularization of technology, presenting this as a low cost solution, the work aims to develop an alternative to natural light harvest, using recycled and reused materials, making it an environmentally friendly product and good efficiency.
