Zafè ki bezwen atansyon lè w ap chwazi ekleraj salklas
Konsantre nan ekleraj salklas se seleksyon an nan lanp. Anviwònman ekleraj la nan salklas la ta dwe satisfè egzijans ekriti elèv yo ak pwofesè yo sou Desktop la ak tablo nwa. Se poutèt sa, lè w ap chwazi lanp ak antèn, yo ta dwe konsidere karakteristik sa yo nan anviwònman salklas la, epi yo ta dwe chwazi fòm lanp rezonab ak metòd ekleraj. Bagay ou dwe sonje yo se jan sa a:
1. Sal klas relativman etwat, jeneralman pa plis pase 6m lajè ak pa plis pase 8m nan longè. Lanp sal klas yo pèpandikilè nan direksyon tablo a sèlman bezwen de kolòn, ak yon total de 4-6 lanp sal klas ka satisfè kondisyon yo ekleraj. Gen anpil plas pou seleksyon nan lanp sal klas sa yo. Osi lontan ke pozisyon apwopriye ak wotè nan lanp yo chwazi, lanp griyaj jeneral ka satisfè kondisyon yo.
2. Nan yon salklas relativman gwo, lanp sal klas ki pèpandikilè ak direksyon tablo a dwe gen plis pase twa kolòn oswa salklas ki gen plis pase 8 lanp enstale. Sal klas sa yo dwe itilize ti lanp griyaj ak griy glas. Dapre fòmil UGR pou kalkile ekla klas la, koyefisyan pozisyon lanp yo sou liy sant sal klas la se pi gwo, ak valè klète sifas lanp yo sou liy sant lan se pi gwo tou, kidonk kantite lanp ki enstale. sou liy santral la ta dwe minimize nan konsepsyon an.
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.
