Beth yw'r problemau gyda goleuadau ystafell ddosbarth ysgol?
Students spend most of their time studying in the classroom. If the classroom lighting is not well designed, it is easy to cause visual fatigue. After a long time, it will lead to the decline of students' eyesight and academic performance. Therefore, we must pay attention to the renovation of classroom lighting facilities. So what are the problems with the lighting facilities in the school classrooms, and how should they be solved? Let's take a look with the teaching office lamp manufacturers now!
1. Many school classroom lighting lamps are placed in an unreasonable direction, resulting in glare. The lighting fixtures in school classrooms are generally in the direction of the level and the blackboard, which makes it easy for the light to directly enter people's eyes. When there is excessive brightness or excessive brightness contrast in the field of vision, students will feel dazzling and affect their vision. This dazzling light is glare. Glare is divided into direct glare, reflected glare and contrast glare. The visual effect of glare reduces the visual effect of the work area, causing visual discomfort and distraction, easily causing visual fatigue and damage to eyesight.
Solution: The arrangement of the lamps should be parallel to the long axis and the students' desks, and perpendicular to the blackboard, so that the light of the lamps will enter people's eyes from both sides of the eyes, avoiding direct sunlight; at the same time, put the lamps It is arranged above the vertical blackboard channel, so that the desktop forms side or two sides lighting, and the lighting effect is better.
2. Mae nifer y ffynonellau golau ar gyfer goleuo ystafelloedd dosbarth ysgol yn annigonol, gan arwain at gysgodion. Nifer annigonol o ffynonellau golau hefyd yw achos yr amcanestyniad. Oherwydd y nifer fach o lampau, mae'r pellter rhwng y lampau yn rhy fawr. Pan fydd y myfyriwr yn eistedd rhwng y ddwy lamp ac yn agos at y lamp olaf, ni all goleuo'r lamp flaenorol belydru i leoliad y lamp olaf. Ni all wrthbwyso'r cysgodion a achosir gan lamp yn disgleirio ar y corff dynol yn effeithiol.
Solution: Because we can't use shadowless lamps like the operating room, we can appropriately increase the number of lamps and change the installation position of the lamps. In places where the light sources are denser, we can appropriately reduce the light intensity and use more low-power lamps. , replacing less high-power lamps.
3. Nid yw'r ffynhonnell golau yn sefydlog. Pan fydd y gefnogwr yn cael ei droi ymlaen, bydd y ffynhonnell golau yn ansefydlog. Oherwydd uchder uchel ystafell ddosbarth yr ysgol, er mwyn atal y golau rhag cael ei effeithio gan y dosbarth uchel, mae'r ysgol yn defnyddio canhwyllyr i hongian y lamp yn yr aer canol ar uchder penodol o'r bwrdd gwaith, ac mae rhai goleuadau ystafell ddosbarth ysgol yn defnyddio hongian meddal, hynny yw Os nad yw'r ffynhonnell golau yn sefydlog, pan fydd y tywydd yn boeth yn yr haf a bod y gefnogwr yn cael ei droi ymlaen, bydd y lamp yn parhau i siglo yn ôl ac ymlaen, gan wneud y ffynhonnell golau yn ansefydlog ac yn effeithio y disgleirdeb. Ar yr un pryd, mae'r corff lamp yn parhau i ysgwyd, sy'n cynyddu'r perygl.
Ateb: Trwsiwch y canhwyllyr meddal a defnyddiwch ddeunydd gyda mwy o galedwch i drwsio'r golau.
