| LED blackboard light |
| Nowadays, students' myopia is becoming increasingly severe with LED blackboard lights. However, students spend most of their time in the classroom. Therefore, in many places, they choose to use classroom lighting to solve the problem of myopia, but there will be hopeful users. This reflects that the feeling of using this special light has not been improved yet, and this is not a problem with the light, but a problem during use, and there is no impact of use. What are the issues and how can you solve them? Let's take a look at the manufacturer of eye protection lights in our classroom.
Many special lights in the classroom are placed in unreasonable directions, which can cause glare. It is easy to directly illuminate people's eyes because the lighting in the classroom is usually horizontal and facing towards the blackboard. If the field of view is too bright or the brightness contrast is too high, students will feel dizzy 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 can reduce the visual effect of the work area, causing visual discomfort and distraction, which can easily lead to visual fatigue and damage to vision.
Solution: Special lighting fixtures should be arranged along a long axis, parallel to the student table and perpendicular to the blackboard. In this way, the light emitted by the bulb can enter the eyes from both sides, avoiding direct sunlight. At the same time, the bulb is placed above the vertical blackboard channel, forming one or both sides of the desktop for better illumination.
2. Insufficient light source for classroom dedicated lights, resulting in shadows. The lack of light source is also the reason for projection. Due to the small number of lights, if the distance between the lights is too far and the student sits between two lights and is close to the latter, the illumination of the former cannot radiate to the position of the latter. The shadow of a lamp that cannot illuminate the human body.
Solution: Due to the inability to use shadow free lighting like in the operating room, it is possible to increase the number of classroom eye protection lights and reposition them at the same time. In areas with dense light sources, the light intensity can be appropriately reduced and lower power can be used. Please replace high-power bulbs. |
