Abstract
The utility model relates to a classroom without 'light reflection' on blackboard. The wall body, which is vertical to the wall where a blackboard is positioned, and close to two sides of the blackboard, is provided with light-proof layers with the length being adaptive to the width of the wall where the blackboard is positioned. The blocked part of each light-proof layer can emit 'specular reflection' natural light, thus eliminating blackboard 'light reflection' phenomenon. The length 'a' of the light-proof layers is determined by the width 'b' of the classroom, with the reduction formula of 'a is more than or equal to 1/4b', wherein '1/4' is 'light reflection coefficient'.
Description
Affiliated technical field
The utility model relates to the nothing " reflective " in common classroom to be used, and especially the nothing " reflective " of preceding two arrange seatses in classroom is used.
Background technology
The common classroom that China is generally using at present has the phenomenon of blackboard " reflective " under the major part natural lighting condition by day very much, make and hindered their study by the writing that is not seen or cannot see teachers' usefulness chalk writing on the blackboard by the student of " reflective ".And blackboard " reflective " mainly occurs in the one or two arrange seats near the classroom wall, and blackboard is smooth more, the seat is the closer to the corner of blackboard one side, and " reflective " is severe more.This is because the window that the outer natural light in classroom sees through near blackboard incident angle has taken place and reflection angle bigger " minute surface reflection " on blackboard, and the one or two arrange seats of close classroom wall is just within the complementary angle angle at " minute surface reflection " beam projecting angle of blackboard.If can stop " the minute surface reflection " of blackboard just can improve student's academic environment greatly, thereby improve student's learning efficiency.
Summary of the invention
In order to solve the problem that has blackboard " reflective " in a lot of classrooms, the utility model provides a kind of structure, can eliminate the blackboard " reflective " in the classroom.
The technical scheme that its technical problem that solves the utility model adopts is: do not influence under the prerequisite of the overall daylighting in classroom, the light non-transmittable layers of the length that the width with blackboard place wall adapts is set near blackboard both sides, classroom at the body of wall vertical with the wall at blackboard place, classroom.Light non-transmittable layers stops the natural light of that part of can the generation " minute surface reflection " on blackboard, thereby has eliminated the phenomenon of the blackboard in the classroom " reflective ".Light non-transmittable layers length " a " is by width " b " decision in classroom, and reduction formula is a 〉=1/4b, and wherein 1/4 is " reflection coefficient ".
The beneficial effects of the utility model are, if 1. to the repacking of old edition classroom then, only need install the light non-transmittable layers of certain-length additional, simple and easy to do, the interior architectural applications structure in old edition classroom can not changed, little to the classroom lighting influence.2. if newly-built classroom has then been built outside the light non-transmittable layers, consider daylighting, also can build several big very little windows of each interval.Two kinds of situation difficulty of construction are all little.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structure chart of the present utility model.
1. blackboard place wall, 2. light non-transmittable layers among the figure.
The specific embodiment
In Fig. 1, use the reflection of light law, the light non-transmittable layers (2) of the length that the width with blackboard place wall adapts is set near blackboard both sides, classroom at the body of wall vertical with the wall (1) at blackboard place, classroom.Just can avoid " reflective ".
Claims (1)
1. the classroom of a no blackboard " reflective " is characterized in that: near blackboard both sides, classroom light non-transmittable layers with the size equivalent length in whole classroom is arranged on the body of wall vertical with the body of wall at blackboard place, classroom; This light non-transmittable layers length " a " is by width " b " decision in classroom, and reduction formula is " a 〉=1/4b ", and wherein " 1/4 " is " classroom blackboard reflective light coefficient ".
