黑板灯中小学教室使用要注意什么?

来源:http://www.wfjszmd.com/ 日期:2022-01-07 发布人:wanfeng 浏览次数:

在学校教室的照明设计中,直接眩光、反射眩光以及光幕反射是经常见到的问题,这是由于教室中照明布置方式不合理或使用裸灯泡、灯管,从而产生直接眩光。
In the lighting design of school classrooms, direct glare, reflected glare and light curtain reflection are common problems. This is due to the unreasonable lighting layout in the classroom or the use of bare bulbs and tubes, resulting in direct glare.
若是黑板灯使用不当,学生看黑板的文字时候就会因为反射眩光而感到难受。有时,课桌的表面也会具有镜面反射成分,而且大多数学生的视角在30度的夹角内的光通量会产生光幕反射。
If the blackboard lamp is not used properly, students will feel uncomfortable because of the reflected glare when reading the blackboard text. Sometimes, the surface of the desk will also have a specular reflection component, and the luminous flux of most students' perspective within an included angle of 30 degrees will produce a light curtain reflection.
通常,教室内采用的都是荧光灯,荧光灯管表面亮度虽不高,但面积大,为了消除眩光和合理配光,应装上灯罩。或将荧光灯全部拆除统一安装新型教室护眼灯。
Generally, fluorescent lamps are used in classrooms. Although the surface brightness of fluorescent tubes is not high, they have a large area. In order to eliminate glare and distribute light reasonably, lampshades should be installed. Or remove all fluorescent lamps and uniformly install new classroom eye protection lamps.
百分百照明LED教室灯蝠翼形配光灯具的优点在于配光曲线合理,尽量避开直接眩光区和光幕反射区;渐开线形灯具的优点是具有25度的保护角,减弱了眩光。教室灯具的安装位置,应处于当教师站在讲台时水平视线以上的45度以外,即让灯具处于微弱眩光区内。
100% led classroom lamp bat wing light distribution lamp has the advantages of reasonable light distribution curve and avoiding direct glare area and light curtain reflection area as far as possible; The advantage of involute linear lamps is that they have a protection angle of 25 degrees and reduce glare. The installation position of classroom lamps shall be 45 degrees above the horizontal line of sight when the teacher is standing on the podium, that is, the lamps shall be in the weak glare area.
黑板灯
安装黑板照明时,应考虑到学生和教师的共同条件。黑板照明的要求是:黑板照度应高于教室一般照明,须有专门照明,学生不应受到黑板的反射眩光的影响,并能很容易地看清黑板上的字迹。照射黑板的灯具直射出来的光不应进入学生的眼内。教师讲课时,不应受眩光干扰,因此黑板照明灯具应装在教师水平视线45度仰角以上。一般为提高黑板的垂直照度,黑板中心的仰角大约是55度。黑板照明有几种方式:嵌入式、顶棚反射式、吊挂式。反射眩光主要来源于光滑表面,可从改变饰面材料来解决。
When installing blackboard lighting, the common conditions of students and teachers should be taken into account. The requirements for blackboard lighting are: the illuminance of the blackboard should be higher than the general lighting of the classroom, and there must be special lighting. Students should not be affected by the reflected glare of the blackboard, and can easily see the handwriting on the blackboard. The light from the lamps illuminating the blackboard should not enter the eyes of students. Teachers should not be disturbed by glare when giving lectures. Therefore, blackboard lighting lamps should be installed at an elevation angle of 45 degrees above the teacher's horizontal line of sight. Generally, in order to improve the vertical illumination of the blackboard, the elevation angle of the blackboard center is about 55 degrees. There are several ways of blackboard lighting: embedded, ceiling reflective and hanging. The reflected glare mainly comes from the smooth surface, which can be solved by changing the finishing material.
如黑板改用磨砂板,甚至用扩散反射的白塑料板代替黑板,吸水颜色笔代替粉笔,不但防止了反射眩光,而且大大地改善教室的卫生环境,有利于师生的健康。
For example, the blackboard is replaced by frosted board, and even the white plastic board with diffusion reflection is used to replace the blackboard, and the water absorbing color pen is used to replace the chalk, which not only prevents the reflection glare, but also greatly improves the hygienic environment of the classroom, which is conducive to the health of teachers and students.
