Materion sydd angen sylw wrth ddewis goleuadau dosbarth
Ffocws goleuadau ystafell ddosbarth yw dewis lampau. Dylai amgylchedd goleuo'r ystafell ddosbarth fodloni gofynion ysgrifennu myfyrwyr ac athrawon ar y bwrdd gwaith a'r bwrdd du. Felly, wrth ddewis lampau a llusernau, dylid ystyried nodweddion amgylchedd yr ystafell ddosbarth, a dylid dewis ffurfiau lamp rhesymol a dulliau goleuo. Mae'r pethau i'w nodi fel a ganlyn:
1. Dosbarthiadau cymharol gul, yn gyffredinol dim mwy na 6m o led a dim mwy nag 8m o hyd. Dim ond dwy golofn sydd eu hangen ar y lampau ystafell ddosbarth sy'n berpendicwlar i gyfeiriad y bwrdd du, a gall cyfanswm o 4-6 o lampau dosbarth fodloni'r gofynion goleuo. Mae llawer o le i ddewis lampau ystafell ddosbarth o'r fath. Cyn belled â bod safle priodol ac uchder y lampau yn cael eu dewis, gall lampau gril cyffredinol fodloni'r gofynion.
2. Mewn ystafell ddosbarth gymharol fawr, rhaid i lampau ystafell ddosbarth sy'n berpendicwlar i gyfeiriad y bwrdd du gael mwy na thair colofn neu ystafell ddosbarth gyda mwy nag 8 lamp wedi'u gosod. Rhaid i ystafelloedd dosbarth o'r fath ddefnyddio lampau gril bach gyda rhwyllau drych. Yn ôl fformiwla UGR ar gyfer cyfrifo llacharedd ystafell ddosbarth, cyfernod sefyllfa'r lampau ar linell ganol yr ystafell ddosbarth yw'r mwyaf, a gwerth disgleirdeb wyneb y lampau ar y llinell ganol yw'r mwyaf hefyd, felly mae nifer y lampau wedi'u gosod. dylid lleihau ar y llinell ganol yn y dyluniad.
3. Use special blackboard lamps. According to the relevant standard requirements, the blackboard lamps cannot have glare effects on the teachers on the podium when working. It is generally believed that blackboard lamps cannot be installed within a range of 45 degree above the teacher's line of sight when a teacher is giving a lecture. This puts forward requirements for the installation height of blackboard lamps. At the same time, considering the possible position conflict with other teaching equipment, it is best to have a blackboard lamp designed to be liftable.
4. The installation positions of lamps can be divided according to the functional areas of the classroom. The classroom is mainly divided into two parts, the podium area and the student desk area. The podium area is mainly the work area of teachers. If the lighting of the blackboard meets the requirements of the standard, there is generally no need to add lamps to illuminate the podium area in this area, and only the blackboard lamps and reflected light can meet the lighting requirements. Student desk area, according to GB 50099-2011 "Code for Design of Primary and Secondary Schools", including the range from 2.5m from the blackboard to 0.6m from the back wall of the classroom. This area must meet the relevant requirements in the standard. The installation location of classroom lamps should also be mainly aimed at this area, rather than installing lamps from the podium.
5. Requirements for special classrooms. Most of the school are ordinary classrooms, in addition to laboratory, art room, computer room, gymnastics room, recording and broadcasting classrooms and other special classrooms, the special requirements of these classrooms should be considered in the design stage. For example, the illuminance limit of the art classroom is 500lx, and the color rendering index of the light source must reach Ra90 or more; special laboratories (physics laboratories, chemistry laboratories, etc.) generally use dark rubber table mats, and the reflectivity of the desk will increase. When descending, students sometimes stand to perform experimental operations, which will block light, so local lighting equipment should be equipped if necessary; the computer room should design the position and height of lamps according to the position of the computer to avoid reflected glare on the computer screen; gymnastics room and Vertical lighting equipment should be added to the recording and broadcasting classrooms, so that students can see the teacher's facial expressions clearly.
