Solar daytime lighting system

The solar daylighting system based on different optical components was proposed by Chi Wei et al. . The system structure consists of four modules. These are light collecting, monitoring, auto-compensating and light mixing modules as shown in Fig. 12.

Solar lights designed for daytime use are products that leverage solar energy to function efficiently throughout the day. 1. Their purpose is to illuminate outdoor spaces without relying on traditional electrical sources. 2. These fixtures harness sunlight during the day, converting it into electricity to power various applications. 3.

Tubular based daylighting system consists of three optical components. One is receiving part based on hemispherical dome which collects sunlight, other is light transporting device which is a light pipe and third one is lower part which works as a diffuser for distribution of the light uniformly inside the room. Solar light pipes are of two types.

By harnessing sunlight, these systems provide illumination that reduces the dependence on artificial lighting during the day. Daylighting systems are engineered to capture, diffuse, and distribute natural light effectively, ensuring bright and well-lit interiors while conserving energy.

They have reported that initial per m 2 cost of any daylighting system is in between USD 600–800 for a linear concentrator and for a point focusing solar concentrator such as Fresnel lens or parabolic reflectors cost is high in the range of 1500–1800 /m 2.

A revolutionary system to bring sunlight to dark rooms. The system consists of the Concentrator that follows the sun and concentrates the sunlight onto the Light cable to one or multiple light distributors – Luminaries – that the user attaches to the ceiling or walls. The system is then operated with an app that also guides the set up procedure.
