Abstract
T.D.G.S., “Tubular Daylight Guidance Systems”, are natural lighting processes based on the transport of light. In 1990, they were judged by Littlefair as the most innovative technology in daylighting [1]. From 1982 to 2020, this paper is a state of the art on the different processes of tubular daylight guide systems. The key words used to carry out the census are light pipe; light tube; light guide; sun pipes; solar pipes; solar light pipes; daylight pipes; tubular skylight; sun scoop; tubular daylighting device; tubular daylight guide systems; mirrored light pipe. A classification by type of process is proposed (collection, transport or diffusion) for each technology identified in the literature.
Highlights
TDGS are part of the daylight conveyors
We find the Hybrid Solar Lighting (HSL) device presented in Mayhoub's publication (Fig. 15)
In contrast to the mirrored pipe offering illumination values ranging from 100 lux to 1200 lux, hollow pipe (HPP) coupled with artificial lighting makes it possible to achieve an average illumination throughout the tube of around 200 lux on average [46]
Summary
Light collection systems are processes that use the refractive or reflective properties of the materials, they can be passive or active. Known as solar trackers, are expensive, but very efficient (thanks to an always optimal collection). They have the disadvantage of requiring regular maintenance. For this census, we will distinguish two types of collectors to carry daylight within the pipe: active and passive systems
