The installation design of classroom lighting and what should be paid attention to
Choosing a good classroom lighting will directly affect students' vision health, so the country now attaches great importance to the transformation of classroom lighting. So do you know anything about classroom lighting? Today, let's take a look at the points of attention about the installation and design of classroom lighting fixtures!
1. The control requirements of classroom lighting fixtures should be parallel to the side windows according to the arrangement direction of the controlled lights. When there is sufficient sunlight during the day, you can only turn on the side lights far away from the windows, which can maintain the uniform brightness of the overall lighting of the classroom and achieve the purpose of saving electricity.
2. Due to the continuous popularization of modern multimedia teaching equipment, many classrooms have installed front projection projectors to replace the heavy and occupant rear projection TVs in the past, which puts forward new requirements for the control method of the headlights. When designing the control method of the lamp, the following issues should be considered: The projection screen usually occupies half of the blackboard area. When the projector is working normally, in order to obtain sufficient screen brightness, you need to turn off the front fluorescent light near the screen. If the way of controlling the lamp is still parallel to the side of the controlled lamp post, the column direction lamp near the screen must be turned off, which will directly reduce the lighting of the middle and rear desks, which will seriously affect the efficiency of students. Therefore, individual control of the front fluorescent lamp is a way to solve the above-mentioned problems.
Similarly, the blackboard light should be controlled separately. The purpose of this is to ensure the brightness of the screen, while the teacher can still teach on the other side of the blackboard.
3. The height of the lamps should be set reasonably. Since the projector is installed on the ceiling, if the positions of the bulb and the projector bracket are not set correctly, the lamp holder will block the screen and form a shadow. Therefore, in the design stage, it is necessary to carefully consider the positional relationship between the two to avoid unnecessary troubles in subsequent projects.
The choice and setting of classroom lighting are usually related to the visual health of students, so both schools and parents need to pay special attention. Of course, the decorator of classroom lights, such as construction units, must also design in accordance with the relevant provisions of national standards.
