External window anti-glare device

Abstract

The invention discloses an external window anti-glare device. A light angle sensor installed outside a window provides an incident light angle signal to a controller to control a stepping motor to move, the stepping motor drives light reflecting louver blades at the topmost layer of a louver window to rotate through a linkage device, and then the other blades are driven to rotate through rotating curtain connection lines connected between all blades to achieve a purpose of driving all light reflecting louver blades on the louver window to rotate; and a solar cell panel installed outdoors is connected with a control panel to provide driving force for the control panel and a motor. According to the external window anti-glare device, the structure is simple, installation is convenient, use is convenient, and the reliability is good; and the external window anti-glare device can not only meet the needs of directly benefit of external window lighting and sunlight incidence, but also can solve the problem that large area window opening is prone to generate glare, meanwhile, the light environment in a classroom can also be improved, the energy consumption of electric lighting is reduced, market potential is great, and in the solar energy use industry, the external window anti-glare device has huge economic and social benefits of promotion and application.

Description

technical field [0001] The invention belongs to the field of building lighting and solar energy utilization, and relates to an automatically adjustable anti-glare device installed on a transparent outer window. The large outside windows of classrooms in the enrichment area can increase the natural lighting rate and fully receive the heat from the sun, but it is easy to cause the contradictory problem of glare on the blackboard and other surfaces. Background technique [0002] The main functions of transparent external windows are lighting, ventilation, and receiving solar radiation, etc., while the main functions of curtains are shading and dimming, blocking external sight, avoiding direct sunlight, heat preservation and sound insulation, etc., in order to adjust the indoor thermal environment and light environment to meet the needs of the indoor environment. different needs of personnel. As we all know, classrooms usually want to set up large-area transparent external wind...

AI Technical Summary

Problems solved by technology

However, a large area of ​​external windows will bring a fatal problem, and it is also the "killer" of myopia for primary and middle school students - glare

When students are in the classroom, due to the strong direct sunlight at noon, the surfaces of desks and blackboards are abnormally bright, resulting in strong bright contrast in the field of vision, causing glare, especially for students in the direction of reflection lines on bright surfaces, which directly affects students. classroom learning quality

At present, although the teaching method of blackboard writing has been partially replaced by multimedia large screen teaching, the projection of too strong light on the large screen will still cause glare and make it difficult to see the content of the large screen

[0003] At present, for the glare problem caused by strong light in the classroom, the curtains are mostly closed manually, but this method reduces natural lighting and solar heat gain at the same time, resulting in the need to turn on artificial lighting equipment in the classroom, increasing lighting energy consumption
