What is the design specification of hotel meeting rooms?

(1) Lighting design and lighting requirements of conference room

1. Illuminance:

Lighting is the basic requirement of video conference room. Because the time of video conference is random, artificial cold light source should be used indoors to avoid natural light. The doors and windows of the conference room should be covered with dark curtains. The light source has no adverse effect on human vision. Three-color lamp (color temperature 3000-3500K) is more suitable. Illuminance requirements are specified as follows:

A) In order to ensure the correct image tone and the camera's self-balance, it is stipulated that the light shining on the participants' faces is uniform, and the illuminance is not less than 500lux. The illuminance near the monitor and projection TV is 50-80lux, so direct light should be avoided.

B) The direction of light is more important than the intensity of light. Installing a diffusion lens for the light can fully diffuse the light and make the participants' faces evenly illuminated.

2. Installation position requirements: Tri-color lights are generally installed on the ceiling of the conference room, and L-shaped frames should be installed on the ceiling, and lamps should be installed at the corners of the L-shaped frames, so that the lights do not directly illuminate the objects and participants, but rely on the reflection and scattering of the lights from the ceiling to illuminate the conference room.

In addition to the above two points, in order to achieve better results, we need to pay attention to: a) avoid direct sunlight on objects, backgrounds and lenses, which will lead to dazzling contrast. B) When the light is weak, it is recommended to use auxiliary lighting, but direct light should be avoided. C) Use auxiliary lighting, and daylight lighting is recommended. It is forbidden to use colored lights and avoid using stroboscopic light sources. D) Avoid direct light from the top or the side of the window, which will directly lead to shadows. E) It is recommended to use indirect light sources or soft light reflected from flat walls.

(B) the layout of the conference room on the impact of lighting and light

Layout principle: ensure the camera effect and achieve the purpose of reproducing clear images.

Layout requirements:

1. In order to prevent the "stealing light" and "reflecting light" effects of color on people's shooting, the background wall should be designed separately, and it is best to use a uniform light color, usually beige or gray, rather than a border. It is forbidden to use chaotic colors with strong contrast to facilitate the setting of camera lens aperture.

2. The other three walls, floor and ceiling of the room should match the color of the background wall, and saturated colors of black or bright colors should be avoided, generally light blue and light gray. It is not suitable for each wall to use complex patterns or hang complex frames, so as to avoid image blurring when the camera moves or zooms, and at the same time increase coding overhead. It is best to seal the windows or install brown glass, or hang thick cloth curtains to prevent direct sunlight.

The camera lens should not be aimed at the door. If the door is taken as the background, the camera lens will expose the light source behind the camera target when people come in and out.

4. Conference tables: It is best to arrange conference tables in rows. At the same time, in order to reduce facial shadows, it is recommended to use a light-colored desktop or tablecloth for the conference table.
