Abstract
A sunlight mirror for increasing the indoor lighting relates to the art of sunlight use. The natural lighting effects in classrooms of schools and kindergartens and families are generally weak, unconducive to visual perception development of students, teenagers and children and myopia prevention and cure f students. The proposal is to arrange the sunlight mirror on the light inlet window or the external or internal side of the light inlet wall in classrooms of kindergartens and schools or families or ordinary houses and project the sunlight reflected by the mirror into the upper part of the room so as to improve the indoor illumination.
Description
[technical field]
The utility model relates to sunshine and utilizes the field, especially indoor daylightings such as the classroom of school kindergarten or family.
[background technology]
Country should not be lower than 1: 6 about setting glass ground, classroom among the classroom lighting standard GB 7793-87 of middle and primary schools than, and the coefficient of lighting minimum on the classroom desk face should not be lower than 1.5%.But the present natural lighting effect of school and classroom, kindergarten and family generally a little less than, begun since the indoor life of building and carrying out the history of various social activitieies from the mankind, all be by the printing opacity door and window of metope or transparent watt of deck are injected indoor with the angle that tilts from top to bottom on the sunny side in the sunshine inlet chamber, the sunshine of injecting from the printing opacity door and window is confined near the door and window, it is bright excessively by sunlit desk face near the inside, school kindergarten classroom faces south metope, west in the afternoon is to inject from student's left anterior-superior part to incident sunlight, the reflected glare that the students' union that faces southern window is produced books face on strong dazzle of direct projection and the desktop is totally unfavorable to eye, it is blocked with curtain in the classroom that has, and has disadvantageously obviously reduced the illuminance in the classroom.Outside the Nan Qiang in the many classrooms of China the corridor is arranged, the classroom Nan Qiang that has only establishes the daylighting fenestella aloft, and these classrooms are south illumination wretched insufficiency on the side desk face within the walls particularly.Sunlight is huge to human beings'health survival and development effect, and is very important especially to the sound development of human vision function undoubtedly.The classroom comprises that to the utilization of sunlight more building seems very passive to the utilization of sunlight, and is very limited but up to the present.
Two during the last ten years, and China student suffers from myopia in a large number.Through discovering: primary on the myopia paathogenic factor is light, and we will grab principal contradiction.In recent years, many animal myopia eye experiments provide useful reference for we explore the anti-vermachen method of myopia of student eye.Zoopery is found: form deprivation can cause brood to suffer from myopia, and near-sighted pathological change has all taken place the axiallength diopter of experimental eye.The experimental technique of form deprivation has: sew up eyelid; Muddy cornea or crystalline lens; More be to adopt semitransparent thin film to hide (Beijing Medical University shows " experimental myopia research " foreign medical science ophthalmology fascicle 1993.17.2:91-94 such as the first Zhu Xiao Song of hospital of Department Of Medicine, Peking University).The form deprivation experimental eye all produces myopia under the normal illumination condition.The form deprivation experimental eye is placed under the full secret note part, find these the eye do not take place myopia (Xu Guangdi " ophthalmology dioptrics " revised edition. Beijing military medicine 2001.1.ISBN7-80121-344-0 of Science Press; 52).
The ophthalmology prior theory thinks that form deprivation is meant that can not get clearly shape on the retina feels that light stimulates, and explains that China student does not have the form deprivation phenomenon except that only a few has cornea or phacoscotasmus, eye ptosis.
Find after deliberation: because light sensation is the basis that shape is felt, it is concentrated expression (Yan Honglu " physiology of eye " the Beijing people health 2001.ISBN7-117-04549-3 of publishing house of light sensation that shape is felt; 253.260).So, the essence of form deprivation is exactly the weakening of light sensation, and the effect after semitransparent thin film hides is that to enter the light intensity of intraocular little, and direct light becomes scattered light, the cell membrane of looking on the retina can not get normal sufficient light stimulus, and cone cell can not get excited completely.Because light stimulus deficiency, drug on the market for the blood supply system of eye, so choroid only needs a small amount of blood supply to get final product, and causes the atrophy attenuation of postretinal tela chorioidea like this, and the retina of being close on it also prolongs after initiatively thereupon, and can cause the sclera of the back utmost point portion of eye that expansion backward takes place.Yan anteroposterior diameter has just prolonged like this, has enlarged eyeball volume (Xu Jun etc. " progress of experimental form deprivation myopia studies " foreign medical science ophthalmology fascicle 2004.2.99-100).The increase of eyeball back/forth diameter makes the eyeball ovalization, causes corneal diopter also to increase.
More than change and point out us: under the pleasing to the eye state of the low light level, can cause an anteroposterior diameter to increase.Therefore, it is pleasing to the eye that prevention and treatment myopia just must be got rid of the low light level, just must provide sufficient light.
Also having a fact is that a large amount of for a long time statistics all show: it all is that the schoolgirl is more than the boy student that cities and towns or rural student suffer from the myopia number.Even also be like this in same class.Observe and find: the boy student of majority likes outdoor activity when break, and after class, great majority active on the court all are the boy students.But, see frequently at a distance that the boy student of outdoor activity their sight line is often alternately on environment, classmate and ball activity.With indoor different be outdoor light, than light much better than in the classroom, 3,000 to 5,000 lx (unit of illuminance: the lux), 10,000 to 20,000 above lx are arranged under the sunshine is arranged also under the non-sun direct projection of outdoor illumination on daytime after measured.Obviously sufficient light has given these boy students' eyes with good stimulation.Cone cell only just can be fully excited under the light stimulus of abundance,
The conclusion that research draws is: be control bathomorphic key and necessary to the suitable sufficient light stimulus of student.Why numerous physical treatment methods can cause the raising in short-term of eyes long sight function, all are to have increased the result that a spot of light stimulus impels has increased some CBFs to eyes.
Undoubtedly, illumination deficiency is the most important cause of disease that produces a large amount of myopia of student eyes.Its performance is exactly: in the residing family of children kindergarten classroom ambient lighting deficiency.Student's schoolwork burden in past is not heavy, and TV does not occur yet.Outdoor the playing that have ample time after class every day, eyes receive sufficient available light, so the myopia incidence of disease is not high.Regrettably: we work out this result but can not be student's lessons " Reduction of Students' Study Load " also can not allow children see how many TVs less more.The animal myopia eye experimental results show that: all can cause animal to produce myopia with form deprivation and two kinds of methods of concavees lens.Promptly weaken pleasing to the eye light and the image focus is prolonged to the retina rear portion and all cause myopia.Known through research now: with seeing far away or the distant vision of myopic animal being restored for the sufficient light of eye.And the student sees the time far away, sees distance far away, is very limited under the heavy situation of schoolwork burden.Avoid too near although add, still be not enough to overcome the factor that distant vision descends with eye.Therefore, unique feasible way is exactly: the illuminance that improves eye-using environment.Because the student is in indoorly, and mainly is in the classroom by day.So the illuminance that improves the classroom is most important to control myopia of student eye.
The scheme that No. 86205932 solar energy housing reflective mirrors of Chinese patent application lighting device proposes, its objective is " on the basis of existing building construction, investing on a small quantity; make that darknesses such as back chamber, basement or corridor are indoor enough sunshine lightings, " to improve indoor brightness, temperature and degree of drying.The technical scheme of its proposition is that " the reflective mirror lighting device being installed on the appropriate locations, window opposite such as building construction back chamber, basement, corridor " is characterized in: " the reflective mirror surface configuration is planar shaped; multi-prismatic surface shape; or cylindrical so, or paraboloidal ".Obviously back chamber is the room of non-sunny slope, the certain illumination deficiency in this class room, but solar light reflecting mirror is installed in " appropriate location, window opposite " in this class back room must be the position that sunlight is arranged, floor is high more to have the position of sunlight far away more, it is big because of distance reflection ray mobile range a little less than solar light reflecting mirror its effective time of short luminous intensity is installed in position far away, and installing space is easily restricted
Chinese patent application 00256953.No. 1, the disclosed a kind of solar energy light collecting mirror of publication number CN2504565 reflects sunray in the direction of setting from different perspectives by the minute surface that is installed on the device, it is characterized in that: the electromechanical integrated device of following the tracks of sunray mainly is made up of five parts, that is: minute surface, vertical drive system, horizontal drive system, probe circuit drive system, base for supporting system.Obviously the solar light reflecting mirror that is used for the classroom does not need so complicated structure and expensive input.

[specific embodiments]
Particularly the outdoor position of the printing opacity wall of the metope on the sunny side of the classroom of universities, middle and primary schools and kindergarten and family or light inlet window or indoor are provided with the solar light reflecting mirror 1 that the sunshine of minute surface reflection can be injected the indoor first half in the house.Introduce sunshine to too little should the making improvements of house south wall light inlet window for facility, enlarge transparent surface.Under the prerequisite that does not influence teaching building load-bearing safety, should increase the classroom lighting face as far as possible, establish large-area glass window or glass wall.For the reflection luminous energy that makes solar light reflecting mirror arrives the classroom first half, southern window top should be as far as possible near ceiling.The minute surface of solar light reflecting mirror 1 is high in the south and low in the north.
Solar light reflecting mirror 1 is made of reflective mirror and support 2 thereof.Support 2 location of solar light reflecting mirror 1 is located at indoor metope light inlet window on the sunny side or the outdoor of printing opacity wall that needs to increase the house of illumination such as the classroom of school or kindergarten and family and (sees accompanying drawing 1) on the wall of the sun; or top or the outside (the seeing accompanying drawing 2) in outdoor balcony, corridor towards the sun; Stall can be located at the outer corresponding window of Nan Qiang and (see accompanying drawing 1,2) on the vacant lot of the sun, or on the adjacent building or indoor.
The minute surface of solar light reflecting mirror 1 is to be arranged by 2 some level crossings to constitute.Desirable 2 or 4 or 6 or 8 reach more polylith (according to the area size of printing opacity wall or window, installable distance, space are selected the demand and the economic condition that increase illuminance in the classroom).
The basal surface that the solar light reflecting mirror 1 that is located at indoor or outdoor balcony, top, corridor comprises support 2 from the height of this room floor more than 2 meters.
Angle on two adjacent planar mirror minute surface east-west directions at 140 degree between 170 degree.
Level crossing in the solar light reflecting mirror 1 can be made by reverse side rubberizing glass mirror or try in vain to break to pieces glass mirror and metal matrix mirror.
Be provided with the structure that the lens carrier angle of inclination is regulated and located on the support 2 of solar light reflecting mirror 1, this structure is taked to be provided with the rotating shaft and the screw rod location structure of both direction in length and breadth in the bottom center of gravity of every eyeglass Small bracket and the whole Big brackets of whole solar light reflecting mirror 1 whole eyeglasses.
The eyeglass Small bracket angle of inclination that is provided with on the support 2 of solar light reflecting mirror 1 is regulated and the structure of location is the reflective angle of regulating every eyeglass respectively.
The eyeglass Big bracket angle of inclination that is provided with on the support 2 of solar light reflecting mirror 1 is regulated and the structure of location is the reflective angle of regulating whole solar light reflecting mirror 1 whole eyeglasses.
Because floor is different with geographical position and season, also have the difference of installation site, the angle of pitch of solar light reflecting mirror 1 and inclination angle, the left and right sides should be regulated after installation on the spot could obtain optimum efficiency.But but in length and breadth the rotating shaft of both direction be meant the minute surface carriage both east-west direction also North and South direction sway and regulate fixingly, this must on-the-spotly adjust according to the actual reflecting effect of sunshine with 1 to 2 day time using.
Be noted that: solar light reflecting mirror 1 device that the classroom is used should adapt to the sunshine of period phase of starting to school, and does not consider the sunshine of cold administration fictitious time section.
Every level crossing in the solar light reflecting mirror 1 is the rectangle or the radial burst shape of determining on bulk rectangle minute surface, radial similar ribs of the fan frame shape, and the former needs bigger light inlet window or printing opacity wall area, but simple in structure; Latter's processing and complex structure, but can adapt to the situation that those inconvenience maybe can not enlarge window.In solar light reflecting mirror 1, need not connect between each eyeglass.The length direction of monolithic eyeglass is a North and South direction.The long limit of the level crossing of being arranged is adjacent, and the angle on the two block length limit adjacent planar mirror minute surface east-west directions, is specifically determined by Field adjustment between 170 degree at 140 degree.
Because earth rotation, east rises the west and falls the sun every day in face of the mankind.Sunlight also can form in the indoor ceiling zone after solar light reflecting mirror 1 reflection and become a camber line shape moving process from West to East.In the Beijing in April, about 4 hours of the time that the sunshine of a flat mirror reflects moves on indoor ceiling from West to East.If a big level crossing only is installed in the solar light reflecting mirror 1 that is provided with for classroom, so it effective use the period under certain reflection angle state as at 10 in the morning to point in afternoons 14, and the student wants between the 11:30 to 14:00 at noon generally that classes are over, and being does not during this period of time at noon need to increase classroom illumination.Therefore it is ill-considered a level crossing being set.Select according to different situations.The angle of adjacent two level crossings also will be regulated after installation and determine.The cross direction extended line of the planar optics at solar light reflecting mirror 1 middle part and horizontal line intersect.Promptly the angle between two adjacent plate plane mirrors of speculum middle part is not 180 degree.In order to allow the student obtain the better illumination period, avoid produce useless solar reflection optical aforementioned noon, to allow the student obtain effective time in giving a lesson the period longer morning and afternoon, the better solar reflection optical of lighting effect.When light inlet window or printing opacity wall enough can satisfy the needs of reflected sunlight greatly, preferred plan was to establish two level crossings, and a sunlight reflected is kept supplying another piece of noon for using afternoon.Variation according to the solar radiation angle was regulated 1～2 time in general one month.This just needs the special messenger to be responsible for.Certainly, the level crossing more than 4 is set, as long as angular adjustment is proper good.
Sunlight because the scattering of ceiling makes light to the scattering of whole classroom, obviously improves the intensity of illumination in the classroom after solar light reflecting mirror 1 reflexes to the classroom ceiling region.In the classroom,, (do not influence solar light reflecting mirror 1 flash back the sunlight classroom ceiling) light solar protection devices is installed in window or outside window where necessary for avoiding sun direct projection or reflected glare.Enter the classroom neither influencing reverberation like this, do not make the student suffer to select under the pleasing to the eye double requirements of dazzle suitable sunshade scheme again.Should not attend to one thing and lose sight of another.
The solar light reflecting mirror 1 that is located at the indoor is to consider to avoid on sunlight injects desk face in the classroom from the top of light inlet window or printing opacity wall.The solar light reflecting mirror 1 that is provided with on outdoor balcony, top, corridor is to consider aforementioned factor, considers safety factor again, so will be located at apart from this room floor more than 2 meters.
The solar light reflecting mirror 1 that is located at family or common house can and be used in combination the setting that requires to suit measures to local conditions with reference to such scheme and get final product.
To being in the classroom on teaching building north, the requirement that increases illumination is higher.Suggestion all is transformed into big window or printing opacity wall to the first half of the north and south wall in south-north oppsite classroom (must be non-load bearing wall), dependence is located at the outer solar light reflecting mirror 1 of Nan Qiang with the top of sunlight reflected to the classroom, north, can be provided with on the ceiling in classroom, north in case of necessity and meet light diffuse scattering device.The effect that only adopts this scheme is than classroom in the south difference, because after reflection light distance and radiating surface have increased, the light time section that is subjected in classroom, north will be lacked, but will become stronger than not having.
For the described person skilled in art of this programme is not unfeasible.
