Integration of Horizontal Light Pipe and Shading Systems in Office Building in the Tropics
Journal of Applied Science and Engineering, 2021 Many high-rise office buildings in the tropics have a full-glazed façade and a deep open-plan space. Without any external shading, the office space has a non-uniform daylight distribution and glare problem.

Characteristics of Indoor Lighting Environment Using Daylight with a Light Shelf [PDF]
International Journal of Environmental Science and Development, 2013 We carried out measurements and lighting simulations of an existing office building in order to clarify the characteristics of indoor lighting environments using daylight with a light shelf. Paired comparison measurements were performed to elucidate the difference between using only a light shelf and using a light shelf with a blind in terms of ...

A Study on Performance Evaluation of Mixed Light Shelf Type According to the Angle of Light Shelf
International Journal of Smart Home, 2015 A light-shelf, one of natural lighting methods, has advantages in constructability and economic feasibility in comparison with other passive natural lighting system. A movable light-shelf enables a user in a room to adjust the angle according to his or her preference to control the amount of indoor light. In addition, a light-self serves as a shield to

Saturation compensation for visible light communication with off-the-shelf detectors
Optics Express, 2021 A photodetector may get saturated if the incident optical power approaches the detector saturation threshold. In such a case, a visible light communication (VLC) system fails to recover the useful transmitted signals. We introduce a saw waveform based response characterization technique when an off-the-shelf avalanche photo-diode (APD) is deployed ...
