Lighting design and light requirements for the auditorium chair:
Light illumination is a basic necessary condition for video auditorium. Because of the randomness of the meeting time of the videoconference, the indoor use of artificial cold light is used to avoid the natural light. The doors and windows of the auditorium were covered with dark curtains. The light source has no adverse effect on human eye vision. It is more appropriate to choose the three primary color lamp (color temperature 3000-3500K). The illuminance requirements are specified as follows: in order to ensure the correct image tone and the self balance of the camera, the light in the face of the participant is uniform, and the illumination should not be less than 500lux. The illuminance near the monitor and projection TV is 50-80lux, and direct light should be avoided. The direction of the light is more important than the intensity of the light. The diffusing lens for lighting can make the light diffuse sufficiently and give the participants a uniform illumination on the face.
2. installation position requirements:
The three color lamp is usually installed on the ceiling of the auditorium. The L frame is installed on the ceiling. The lamp tube is installed at the corner of the L frame, so that the light does not directly illuminate the object and the participants, but the reflection and scattering of the light illuminates the auditorium depending on the ceiling.
