Daylight in occupied spaces has positive benefits, not just on cost but on the occupants' health, well-being, and productivity. Daylighting systems such as light redirecting and light transporting systems bring natural light into building interiors. Light transport systems provide a way to bring daylight deep into enclosed spaces of compact planform buildings with a low volume-to-skin ratio. The literature review indicates that light pipes and light-carrying optical fibres are widely used transportation mediums. Literature elucidated the need to study the performance, light distribution characteristics, and relative assessment of system components at different locations to assess their suitability.
The current work focuses on studying the performance of light pipes (horizontal and vertical) and fibre optic systems using ray tracing simulation. The study analyses spatial and temporal light distribution characteristics of light pipes with different collector-diffuser configurations based on predefined criteria (Daily Useful Daylight Illuminance and uniformity). Location-specific light pipe configuration for enhanced daylight distribution will be proposed. The research will also focus on the effectiveness of fibre optic cable for daylight transmission. The effect of fibre bundle efficiency factor will be studied to determine the optimum packing density with varying diameters. Further, fibres' light distribution characteristics will be analysed for the influence of different components and interface elements on system performance.
