Reception area lighting design

　　The front desk is the place where the company shows a good image. In addition to the decoration design of the front desk, the temperament of the staff and the decorations, this area pays attention to the light and shade distribution of the overall space and the fit of the spatial order, which can give people a comfortable and gentle feeling.

Also need to pay attention to the control of glare and brightness ratio. However, for the division of different layouts and the distance and density of the space, different methods should be used for design.

Independent office lighting design

For example, the illuminance of the office area (writing desk) is required to be above 500LX, so as to have sufficient illuminance to ensure normal office needs. For the small area for negotiation, local lighting can be used, such as setting up table lamps, floor lamps, or designing small spotlights and wall lamps on the wall to meet the required lighting effects, and pay attention to the difference between office and negotiation light. transition between.

general mode

　　Focus on reflecting the compactness of the participants and create a better discussion atmosphere. Generally, the method of the middle illumination is higher than the surrounding illumination (or the surrounding lights are turned off to highlight). The overall color temperature is controlled at 3000K, and the average illumination is above 400LX.

Projection mode

　　In the slide show and the content and patterns on the projection can be clearly seen, the text recording work of the participants should also be considered. Therefore, the surrounding illumination setting should be around 150LX. At the same time, taking into account the relationship between the participants and the projection distance and the overall energy-saving effect, a stepped design is implemented for the contrast, and the brightness is gradually increased from the front row to the back.

speech mode

　　Based on the principle of highlighting the speaker's image and not affecting the speaker's feeling, the illumination ratio of the podium should be controlled at 90%-100%, the auditorium and other positions should be adjusted to 50%-60%, and the basic illumination should be controlled at about 200LX.
