Recording classrooms have become increasingly popular and are now a staple in modern educational institutions. This trend necessitates higher standards for lighting arrangements to ensure high-quality video production. This blog explores the key considerations and recommendations for lighting design in recording classrooms, aiming to meet filming requirements and enhance the comfort of both teachers and students.
Key Considerations for Lighting Design in Recording Classrooms:
1. Illumination Intensity:
Proper illumination is a fundamental requirement for classroom filming. Natural light should be avoided, and artificial light sources should be used instead. LED panel lights are recommended for their high efficiency, soft light, reduced shadows, glare-free properties, and long lifespan. Adjustable recessed LED lights can be used for front lighting to allow easy adjustments. The lighting system should be controlled in separate circuits, with all switches centralized in the control room.
2. Overhead Lighting:
Ultra-thin panel lights with a color rendering index (CRI) of Ra≥93 and a color temperature of 5600K are ideal for overhead lighting. These lights should provide uniform illumination without flickering to evenly light up the entire recording classroom.
3. Illumination Levels:
The illumination level for the filming area, especially the face of the person being filmed, should be approximately 500 lux. To avoid uneven facial lighting, adjustable recessed LED lights should be angled appropriately. For monitors and projectors, the surrounding illumination should not exceed 80 lux and should be maintained between 50 to 80 lux to avoid affecting the viewing experience. The illumination for document and chart areas should not exceed 700 lux to ensure clear visibility of text and graphics.
4. Teacher’s Lighting:
The teacher is the focal point in a recording classroom, and the lighting should enhance their appearance, which can influence the quality of the recorded lessons. Front lighting should be positioned at a horizontal distance of 1200-1800mm from the teacher, using adjustable LED panel lights to highlight the teacher’s facial features. The lighting design should ensure uniform light distribution, appropriate brightness, and flicker-free performance.
Implementing these lighting strategies will not only improve the visual quality of recorded lessons but also contribute to a professional and engaging learning experience. For further advice on lighting solutions for recording classrooms, feel free to contact us.
