What role does blackboard light play in education lighting
In the process of new construction or upgrade, many schools are often told 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 light a classroom light? What is the difference between the two? What if only the classroom light is installed and the blackboard light is not installed?
In a sense, the blackboard lamp is a kind of classroom lamp, but when it is used in classroom lighting, the main function of the classroom lamp is to illuminate the student's desktop, so that the student has a good reading and writing environment. The main function of the blackboard lamp is to illuminate the blackboard area, so that teachers can write on the blackboard smoothly, so that students can clearly see the text on the blackboard.
Classroom lighting is more common in the classroom, with the following characteristics: 1. Grid anti-glare; 2. High display; 3. Professional eye protection; 4. Energy saving; 5. Long life; 6. Green and environmental protection. These characteristics well meet the needs of classroom lighting and provide students with a professional lighting environment.
In the design of classroom lighting fixtures, the classroom lights should be evenly arranged longitudinally, and the vertical distance between the lights and the table should not be less than 1.7 meters, that is to say, the installation of the classroom lights should refer to the height of the table. The height of desks in primary and secondary schools is generally around 70cm, and the height of desks in kindergartens is generally around 50cm.
The design of the blackboard lamp is different from the design of the classroom lamp. The blackboard lamp should be a special blackboard lamp with asymmetrical strong light distribution characteristics. The blackboard lamp should be installed parallel to the blackboard, 0.7m-1.0m parallel to the blackboard, and 0.1m-0.2m perpendicular to the upper edge of the blackboard. The control angle of the blackboard lamp should be adjusted to avoid direct glare to the teacher.
