The Importance of Lighting Design for Classroom and Blackboard Lights?

The classroom lighting scheme and implementation have great operability. Even a very excellent classroom light, classroom lighting design, if lacking installation experience and improper installation angle, can still produce adverse results.

2. Classroom lighting mainly includes two parts: classroom lights and blackboard lights. Classroom lights mainly refer to the main lighting in the entire classroom, with their illuminance and light covering the entire desktop and classroom; The other is blackboard lights, classroom lights, which are mainly used to illuminate the words and exercises on the blackboard. The installation and lighting design of classroom lights are related to the size of the classroom and the layout of the lighting fixtures. If the design is not good, even lamps with good brightness will have a significant gap between the actual effect and the expected one. Not meeting the standards. In addition, even with excellent lighting angles, blackboard lights can still cause visual discomfort to students and teachers due to improper installation. Even unable to see the blackboard clearly, causing glare, etc.

Before installing classroom lighting fixtures, it is necessary to first simulate the lighting conditions and then install them based on actual experience in order to achieve a comfortable lighting environment.

So, to create a good blackboard lighting, the following points need to be achieved:

1. Vertical illumination: Blackboard is the focal point of students' attention, and classroom lighting renovation requires a high vertical illumination that meets the national standard value of ≥ 500lux.

2. Uniformity of illumination: As the blackboard serves as a key area for displaying knowledge, the more uniform the distribution of light, the more comfortable the visual experience, and the uniformity of illumination is ≥ 0.8.

3. Glare: Reflection glare and direct glare are common problems in blackboard lighting. In order to eliminate the glare effect in blackboard lighting, the following three conditions need to be met. Blackboard lighting does not enter students' eyes through the reflected light on the blackboard surface; The light source for blackboard illumination does not directly enter students' eyes; The teacher doesn't feel the blackboard lighting dazzling.

4. Reasonable lighting design; In order to avoid problems such as reflection glare and direct glare, the installation position and angle of the blackboard lamp need to be professionally designed for lighting. The following is the layout diagram of the blackboard lamp.

5. Individual control switch: In order to facilitate the lighting of the blackboard to change according to different teaching environments, it is recommended to control the switch separately for blackboard lighting.

6. High quality blackboard lighting fixtures: In addition to meeting the above requirements, high-quality blackboard lighting fixtures play a crucial role.
