The lighting design of the conference hall is a very important factor for obtaining the right visual perception effect. An outstanding conference hall can not only provide a quiet meeting environment for the staff participating in the meeting, but also make it a fact that has a better sense of presence and enhances the meeting. The effect of the hall, because of the use of camera assembly, the lighting, color, background, etc. of the conference hall have a great impact on the quality of the video file image. Camera is a professional knowledge. It is recommended to use a decoration company with professional camera knowledge when decorating the conference hall. Design and make
The following will briefly introduce the principled requirements involving lighting in the design of the conference hall:
(1) Lighting design and lighting requirements of the conference hall
1. Illumination:
Lighting intensity is a basic requirement of the conference hall. Because the time of the video conference is RAND, artificial cold light sources are used indoors to prevent natural light from the doors and windows of the conference hall. Dark curtains should be used to block the light source to the human eye. If there is no adverse effect, choose the three primary color lamp (color temperature 3000-3500K), which is more suitable. The illumination requirements are as follows:
A) In order to ensure the correct image tone and self-equalization of the camera, it is stipulated that the light mapped on the face of the prospector should be symmetrical, the illuminance should not be less than 500lux monitor, the illuminance near the projection TV should be 50-80lux, and direct radiation should be prevented Light
B) The direction of the light is more important than the intensity of the light. A diffuser lens is installed for the light, which can make the daylighting full and diffuse, so that the face of the prospector will have a symmetrical daylighting.
2. Installation location requirements:
The three-primary color lights are generally installed on the ceiling of the conference hall. An L-shaped frame should be installed on the ceiling. The lamp tube is installed at the corner of the L-shaped frame, so that the light does not directly map to the object and the audience, but depends on the reflection and scattering of the light from the ceiling Illuminate the meeting hall
In addition to the two points mentioned above, in order to achieve better results, you need to pay attention to:
A) Prevent direct sunlight from hitting objects, backgrounds and lenses, which will lead to dazzling and high-contrast environments
B) When the light is weak, it is recommended to use the auxiliary light, but to prevent direct sunlight
C) Use auxiliary lights, it is recommended to use daylight-type lights, prohibit the use of colored lights, and prohibit the use of high-frequency light sources
D) Prevent the top light and side light from being directly mapped from the top or outside the window, this kind of mapping will directly cause shadows
E) It is recommended to use an indirect light source or a softer light reflected from a flat wall
(2) The influence of the structure of the conference hall on the light and light
Structural principle: to ensure the camera effect to achieve the purpose of reproducing clear images
Structural requirements:
1. In order to prevent the "dazzling" and "reflective" effects of color on people's photography, the background wall should be designed separately. It is best to use a symmetrical light color, usually beige or gray. It is not suitable to use the format, and the use of strong contrast is prohibited. Color to facilitate camera lens aperture configuration
2. The other three walls, floors, and sky panels of the room should match the color of the background wall. Avoid using saturated colors of black or bright colors. Usually light blue, light gray, etc. are not suitable for each wall. Patterns or hanging complicated frames to avoid trance signs when the camera is moving or zooming. At the same time, it is best to increase the code to open or close the windows or install brown glass. You can also hang thick cloth curtains to prevent direct sunlight.
3. If the camera lens is pointed in front of the door, if the door is guarded as the background, the staff entering and exiting will expose the camera lens to the light source behind the target.
4. Conference table: It is better to arrange the conference table in a row style. In order to reduce facial shadows, it is recommended to use a light-colored tabletop or a tablecloth for the conference table.
