School led lighting design requirements
1) Classroom desks are generally arranged in a regular arrangement facing the blackboard, and the lighting method with uniform lighting on the ceiling should be adopted.
It should be 2.5-2.9m, and the distance from the desk should be 1.7-2.1m.
2) Optical laboratory, microscope experiment table in biological laboratory, experiment table in geography classroom of simple planetarium, or places requiring careful observation and recording. Local LED lighting should be installed. Such as led spotlights, led downlights
3) The control switch of classroom lighting should be set in sequence in the direction parallel to the outer window (the blackboard lighting switch should be installed separately). When there is a projection screen, the lighting switch near the projection screen should be able to be set independently, and it is advisable to turn off part of the corridor LED lighting during class. Smart LED lamps can also be used.
4) The LED lighting of the multimedia classroom should meet the requirements of vertical illuminance, and the general lighting near the screen should be able to be turned off independently, so that the screen content can be seen clearly to meet the normal visual requirements.
5) The installation height of the lamp has a certain influence on the lighting effect. When the height of the lamp increases and the illuminance decreases, the installation height decreases, the glare increases, and the uniformity decreases. The installation height of the classroom lamps from the ground can be solved by using LED fluorescent lamps.
6) There are many lamps in the amphitheater (co-class classroom or lecture hall), and glare interference will increase. It is advisable to choose lamps with better glare limiting performance, such as LED lamps with grille or diffuse reflector (cover) for protection Open luminaires with larger angles.
7) For classroom lighting such as painting and arts and crafts, natural lighting from skylights facing north is generally the best lighting. Therefore, in order to display objects more realistically in painting, arts and crafts and other classrooms, high color rendering light sources should be used and indirect lighting should be used to truly express the shadows of the objects.
8) The lecture halls, large classrooms and other places of TV teaching should be equipped with lighting for taking notes and general lighting used in TV teaching, and general lighting should be dimmed.
9) A special blackboard lamp should be installed in front of the blackboard in the classroom, the average value of its vertical illuminance is greater than or equal to 200lx, and the uniformity of illuminance on the blackboard surface is greater than or less than 0.7. It is advisable to use a special blackboard lamp with asymmetric light intensity distribution characteristics. The protection angle of the lamp on the side of the student seat should be greater than 40 degrees, and no direct glare should be produced.
10) Bookstore lighting should adopt narrow light distribution or other suitable light distribution lamps, and the distance between lamps and flammable objects such as books should be greater than 0.5rn. The power distribution box for the bookstore lighting should have a power indicator and be located outside the bookstore, and the bookstore channel lighting should be independently set up with switches (switches that can be controlled in two places are set at both ends of the aisle).
11) For the studio's studio, the vertical illuminance (artistic performance) should be 1000-1500lx. The electricity consumption of the studio lighting is estimated at 0.6-0.8km/m in the preliminary design. When the height of the studio is less than 7m, it is advisable to use track-type lighting, and when the height of the studio is higher than 7m, a fixed lighting method can be used. Emergency lighting should be provided when the area of the studio exceeds 200rn`.
12) Principles of lighting fixture layout. It is arranged above the passage with the long axis perpendicular to the blackboard, and the lighting effect is the best. If the lamp has a good horizontal light distribution, it can effectively control glare, the lamp protection angle is large, the brightness of the lamp surface is not much different from the ceiling surface, and the lamp layout can also be parallel to the blackboard.
13) Lighting of the reading room. When there is a suspended ceiling, it is advisable to use a dark-coated LED fluorescent lamp, and its general lighting should be controlled along the parallel direction of the outer window or branched control. The sockets in the reading room should be set equal to or more than 15% of the number of seats in the reading room.
14) Computer classroom lighting. Should avoid the visual impact on the display screen by high-brightness light sources such as lamps and windows, it is advisable to choose lamps with bat-wing light intensity distribution characteristics.
15) There should be one or more sets of power safety sockets on the front and back walls of ordinary classrooms and lecture classrooms (combined classrooms).
16) The public lighting in the library and the lighting in the work (office) area should be distributed and controlled separately.
