The electric lighting is responsible for 15% of the electricity consumption, the efficiency inthis sector has a good progress in recent years, it can still improve more. Conventional energysources are polluting and limited, so it is essential to use less aggressive energies with theenvironment. In lighting, this premise is being implemented in a cross-cutting manner, but inresponse to varied and sometimes contradictory interests. The development of lighting devicesbased on solar radiation is an inalienable objective, as is the use of artificial lighting sources that areclean with the environment. To achieve these two objectives, it is essential to know and study thedesign techniques of non-image optics. In the present work we present new systems designtechniques and lighting elements: ray tracing optimization technique, light vector field technique.As well as its implementation and application in various areas of lighting: lighting in officebuildings, libraries museums. We show that renewable energy strategy in the field of lighting notonly produce energy save, also produce good effects in other aspects of human life like well-being,productivity and heritage conservation.
