Free Tubular Daylighting System

Tubular Daylighting System, namely light tube lighting system is a set of natural light collection, and transmitted to the indoor through the pipeline, natural light lighting system.

The working system is composed of three subsystems: daylighting system, light guiding system and diffusing system. The main components contained in the subsystem include: daylighting hood, rainproof cap, fixed ring, straight barrel, bend pipe, extension pipe, diffuser, decorative piece and other auxiliary materials.

Working principle

As a kind of non-electric lighting system, the buildings using this system can use the sunlight for indoor lighting during the day. The basic principle is that outdoor natural light is efficiently collected through the daylighting cover and imported into the system for redistribution, and then transmitted by the special light guide tube, the diffuser at the bottom of the natural light uniformly and efficiently illuminates any place that needs light. From dawn to dusk, even on cloudy days, the light guide tube daylight lighting system into the indoor light is still sufficient. The device is mainly composed of three parts: lighting device, light guide device and diffusing device.

Daylighting device: also known as daylighting cover, is a light tube daylighting system exposed to the outdoor components, collect sunlight. Airtight performance, watertight performance, wind pressure resistance and impact resistance are important performance indexes. At present, most daylighting covers are hemispherical, whose light collection effect is stronger than traditional skylight and daylighting skylight. The main materials are PMMA (acrylic) material or PC injection molding material. The impact resistance of pc material is better than that of acrylic material, but the light transmission rate of acrylic material is better than that of pc material. Each has its advantages and disadvantages.

Light guide device: also known as light guide tube, is the key component of light transmission, its internal surface reflection ratio has a great impact on the efficiency of the system. In order to ensure a high transmission efficiency of the whole system, the tube wall material with high reflection should be used.

Diffuser: The main function is to collect outdoor natural light as much as possible and evenly distributed to the indoor, in addition to ensuring reasonable light distribution, but also should have a high transmission ratio, improve the efficiency of the whole system.
