黑板灯在教育照明中起到了什么作用?

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

多学校在新建或者升级改造的过程中,往往会被照明设计师告知,教室内除了需要配备教室照明灯外,还应安装黑板灯。那么问题来了,黑板灯不就是教室灯吗,两者之间有什么区别,如果只安装教室灯,不安装黑板灯又会怎样?
In the process of new construction or upgrading, many schools are often informed by lighting designers that in addition to classroom lighting, blackboard lights should also be installed in the classroom. So the question is, isn't the blackboard lamp the classroom lamp? What's the difference between the two? What if only the classroom lamp is installed and the blackboard lamp is not installed?
在某种意义上讲,黑板灯是教室灯的一种,但是在应用于教室照明的时候,教室灯的主要作用是照亮学生们的桌面,让学生们拥有一个良好的读书写字环境。而黑板灯的主要作用就是照亮黑板这一块区域,让老师能够顺畅的书写板书,学生们能够清晰的看清黑板上的字。
In a sense, blackboard lamp is a kind of classroom lamp, but when applied to classroom lighting, the main function of classroom lamp is to illuminate students' desktop and let students have a good reading and writing environment. The main function of the blackboard lamp is to illuminate the blackboard area, so that the teacher can write on the blackboard smoothly, and the students can clearly see the words on the blackboard.
校园护眼灯
教室灯常见的拥有如下特点:
Common classroom lights have the following characteristics:
1.格栅防眩;
1. Grid anti glare;
2.高显指;
2. High display finger;
3.专业护眼;
3. Professional eye protection;
4.节能省电;
4. Energy saving and power saving;
5.超长寿命;
5. Super long service life;
6.绿色环保。这几大特点很好的满足了教室照明的需求,为学生们提供专业的照明光环境。
6. Green environmental protection. These characteristics well meet the needs of classroom lighting and provide students with professional lighting environment.
教室照明灯具在设计方案时,教室灯应该纵向(灯具长轴垂直于黑板)均匀布设,灯具距离课桌垂直距离不低于1.7米,也就是教室灯的安装是参考自课桌高度,中小学的桌子高度一般是70cm左右,幼儿园的桌子高度一般是50cm左右。
In the design scheme of classroom lighting lamps, the classroom lamps should be evenly arranged longitudinally (the long axis of the lamps is perpendicular to the blackboard), and the vertical distance between the lamps and desks should not be less than 1.7m, that is, the installation of classroom lamps refers to the height of desks. The height of desks in primary and secondary schools is generally about 70cm, and the height of desks in kindergartens is generally about 50cm.
而黑板灯的设计方案则与教室灯不同,黑板照明应采用有非对称强光分布特性的专用黑板灯具,黑板灯应平行于黑板安装,平行距离黑板0.7m到1.0m间,距离黑板上缘垂直距离0.1m到0.2m,应通过调整黑板灯控照角度,避免黑板灯对教师产生直接眩光。
The design scheme of the blackboard lamp is different from that of the classroom lamp. The blackboard lighting should adopt a special blackboard lamp with asymmetric strong light distribution characteristics. The blackboard lamp should be installed parallel to the blackboard, with a parallel distance of 0.7m to 1.0m from the blackboard and a vertical distance of 0.1M to 0.2m from the upper edge of the blackboard. The control angle of the blackboard lamp should be adjusted to avoid direct glare to teachers.
