This article will introduce the video conference room design is the lighting requirements of principle:
(A) the room lighting design and lighting requirements
1. illumination:
Light illumination is a basic video conference room, because TV meeting time with randomness, indoor artificial cold light source, avoid natural light. Conference rooms and doors with dark curtains shielding. Light on the human visual system without adverse effects. Select the trichromatic lamps (color temperature 3000-3500K) more appropriate. Illuminance requirement as follows:
A) in order to ensure the correct image tone and camera since the balance requirement of the participants in the face of the light was homogeneous, the illumination shall be not less than 500lux. Monitors, Projection TV nearby illumination 50-80lux, avoid direct light.
B) lighting direction than light intensity is more important, to diffuse lighting installation, you can make the lens fully diffuse light, so that the participants face uniform illumination.
2. installation position requirements:
Trichromatic lamps General installation on the ceiling in the room, to the ceiling installation L-frames, the lamp is installed in the L-shaped frame corner, direct rays of the light not to objects and participants, and rely on the ceiling on light scattering light reflection and meeting rooms.
In addition to the above two points, in order to achieve better results, you need to note:

C) use the secondary light, solar light is recommended. The prohibition of the use of coloured lights, avoid the use of frequency Flash source.
D) avoid from the top or the window to the top, side and the direct rays of light, this kind of exposure will lead directly to the shadows.
E) recommend the use of indirect lighting or from flat wall reflection of the relatively soft lighting.
(2) room layout on the influence of light and lighting
Layout principles: to ensure effectiveness to achieve reproducible camera clear image.
Layout requirements:
1. in order to prevent the color pair people photography produce "take photo" and "reflective" effect, the walls should be separate design, it is best to adopt uniform light color, usually use beige or grey, not format, the prohibition of the use of confusing color contrast to facilitate camera lens aperture settings.
2. the other three sides of the room wall, floor, ceiling, the walls should be and color match, jiyong black or bright colors saturated color, usually blue, light grey, etc. Each wall is not suitable for complex patterns or hanging complex picture, in order to avoid camera movement or zoom the image produce blurry when, at the same time increase the coding overhead. It is best to the window seal or install Tan glass or hanging thick cloth curtain to prevent direct sunlight.
3. camera lens should prevail at the door, the door as a background, access makes the camera lens on the camera target behind light exposure.
4. table: the table laid out using row-better. At the same time, to reduce facial shadows, the Conference recommended light desktop or tablecloth.
