Experimental Analysis on a 1:2 Scale Model of the Modified Double Light Pipe

Journal of Daylighting, 2022
This paper is focused on the daylighting system named Modified Double Light Pipe (MDLP) designed by the authors as an evolution of the Double Light Pipe to eliminate the drawbacks due to its encumbrance and the high luminance of its upper portion.

Daylight performance of horizontal light pipe and shading systems in office room with bilateral opening

IOP Conference Series: Earth and Environmental Science, 2023
Abstract Daylighting implementation in the building can reduce building energy use. Previous research about Horizontal Light Pipe and shading systems in the Tropics examined daylighting strategies in a room with a unilateral opening, which receives daylight through a window in one wall.

Daylight autonomy improvement in buildings at high latitudes using horizontal light pipes and light-deflecting panels

Solar Energy, 2020
Abstract Horizontal light pipes (HLP) have shown the potential to convey daylight deeper into buildings. The wide variation in incident angles of sunlight rays and the resulting numerous interreflections of light rays within the pipe are the main reasons for the limited light transmittance of such light pipes during certain daylight periods.

Daylight performance of horizontal light pipe with egg-crate reflector in the tropics

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Horizontal Light Pipe (HLP) is one of a light transport system that can guide daylight deeper into building interiors. Improvement of HLP’s light distribution by installing an egg-crate reflector at its opening distribution was conducted.

Development of a simple light pipe from a Fresnel lens [PDF]

Warasan Witthayasat Lae Theknoloyi Mahawitthayalai Mahasarakham, 2020
This research developed a simple light pipe from using a Fresnel lens as a light source to supply natural light to a light pipe made of a zinc sheet. The objectives of the study were to (1) find the best focal length or focal distance of the Fresnel lens

The effect of a horizontal light pipe and a custom-made reflector on the user’s perceptual impression of the office room located at a high latitude

Energy and Buildings, 2021
Abstract This paper describes a qualitative study on user opinion of daylight supplementation via a horizontal light pipe (HLP) applied in a test office in a building located in southern Norway. The study is part of a full-scale long-term study analysing lighting energy consumption and the photometry of supplemented light. This study employs a custom-
