Anti-glare device for exterior windows

Abstract

The invention discloses an anti-glare device for external windows. A light angle sensor installed outside the window provides a controller with an incident light angle signal to control a stepping motor to move. The louver rotates, and then the other blades are driven to rotate through the connecting line between the blades, so as to drive all the reflective louvers on the louver to rotate; the solar panel installed outdoors is connected to the control panel as the control panel and The motor provides the driving force. The invention is simple in structure, easy to install, easy to use, and strong in reliability. It can not only meet the needs of directly benefiting from external window lighting and sunlight incidence, but also solve the problem that large-area windows are prone to glare, and at the same time can improve classroom lighting. It has great market potential to improve the light environment and reduce the energy consumption of electric lighting, and its promotion and application in the solar energy utilization industry has huge economic and social benefits.

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
