Large prism light-catching module

Abstract

The invention discloses a large prism light-catching module. The large prism light-catching module comprises a light transmission basal layer and a large prism layer fixedly arranged on the basal layer, wherein the large prism layer comprises multiple prisms which have the same cross section and are arranged in a parallel connection manner; and each prism comprises three edge surfaces which are respectively a first surface fixedly connected to the basal layer, a second surface connected to one side edge of the first surface and a third surface connected to other side edge of the first surface.The width of the widest edge surface in the first surface, the second surface and the third surface is 6mm. The angle of a prism system module can be automatically or manually adjusted according to the angle of incident light so as to change the angle of refracted light, so that light is guided into a roof ceiling; and the light-catching area can be increased after the light is reflected by the roof ceiling. The large prism light-catching module has the characteristics of increasing the indoor light-catching area and reducing the possibility of causing glare and can save lighting and corresponding energy consumption of air conditioners.

Description

technical field [0001] The present application relates to the field of architectural technology, in particular to a large prism lighting module used for architectural lighting. Background technique [0002] With the continuous development of green building and building energy-saving technology, as well as people's increasing demand for a healthy and comfortable indoor environment, expanding the natural lighting area and obtaining a good indoor light environment has become an important direction for the development of green building technology. [0003] In the prior art, the traditional prism-film glass daylighting system is to sandwich the micron-sized prism film in the inner cavity of the double-layer glass or stick it behind the glass. It reduces artificial lighting by introducing natural light into the depths of the room, which reduces the energy consumption of architectural lighting to a certain extent, but it still cannot avoid problems such as inability to adjust and p...

AI Technical Summary

Problems solved by technology

It reduces artificial lighting by introducing natural light into the depths of the room, which reduces the energy consumption of architectural lighting to a certain extent, but it still cannot avoid problems such as inability to adjust and possible glare at certain times

[0004] Since the microstructure in the prism film is a micron-sized triangular prism, there is a blazing grating phenomenon when sunlight penetrates, causing an incident light to diverge upwards and downwards, so at a certain incident angle, some strong light is downwards, resulting in glare.
