HYBRID SOLAR LIGHTING SEBAGAI ALTERNATIF TEKNOLOGI PENERANGAN ALAMI BANGUNAN UNTUK EFISIENSI ENERGI DAN PEMANFAATAN ENERGI TERBARUKAN

Abstract

Artificial (electric) and direct lighting technologies available today have the
potential to greatly reduce the growth rate of electricity consumed through lighting
worldwide. While electric lighting has been inefficient throughout much of its
history, direct (natural) lighting is nearly free and often plentifully supplied by the
sun. However, electric lighting systems are necessary when solar lighting is not
adequate and these technologies are being greatly improved.
One relatively new method of lighting a building’s interior combines both artificial
and direct lighting to maximize efficiency is accomplished through the use of a
paraboloidal, mirrored dish which actively tracks the sun to concentrate sunlight
into an array of fiber optics.
