Daylighting has a very effective role in reducing power consumption and improving indoor
environments in office buildings. Previously, it was not under consideration as a major …

We present the design, optical simulation, and experiment of a modified optical fiber
daylighting system (M-OFDS) for indoor lighting. The M-OFDS is comprised of three sub …

The illumination performance and energy savings of a solar fiber optic lighting system have
been verified in a study hall-corridor interior. The system provides intensive white light with a …

Every optical system for sunlight concentration requires following the sun in its movement.
The sun tracking method is essentially chosen on the base of collection geometry and …

In this paper, we present a design and optical simulation of a daylighting system using a
novel design of linear Fresnel lens, which is constructed based on the conservation of …

The geometry effect is one of the effective methods to modulate the photoelectric properties
of photovoltaic units. Herein, we investigate the geometry effect on the optical absorption …

The transmission properties and coupling of solar light have been studied for glass core
multimode fibers in order to verify their benefits for a solar fiber optic lighting system. The …

Daylighting systems, which collect and transport sunlight directly into building interiors for
illumination, can reduce conversion losses between different forms of energy, and thus …

Directly transporting sunlight for use in indoor lighting applications is an efficient way to
utilize solar energy. This study proposes a tree-structured light guiding system (TLGS) to …

An innovative and simple method, exploiting a pinhole camera to perform the sun tracking, is
proposed. The tracking technique has been applied to a sunlight collection system, based …
