Introduction to the practice of seeing light without lights in the museum

If the lighting in the museum does not consider the problem of lighting and lamp hiding from the beginning, then it can only be remedied in the later period, lighting generally follows the effect of seeing light and not seeing lights, let DG briefly introduce these practices.

The usual practice is to make the ceiling and all the pipelines and lamps black, and then cast light to the exhibits or exhibition walls, which looks close to "seeing the light without seeing the lamp". However, this practice should pay attention to two points: first, the lamp should not leave stray light on the ceiling, and the second is that the anti-glare Angle of the lamp itself should be large, if it is too small, there will be glare, which is not conducive to hiding the lamp. However, sometimes the smallpox is white, this method will not work, then what? At this time, you need to do the lamp slot, where the lamp needs to be distributed, do a long dark slot, the surface of the lamp and the dark slot are made of black, with deep anti-glare lamps, you can also achieve good results. This kind of dark slot is narrow and deep, and the effect of light hiding will be better. If the slot is wide and shallow, the effect is worse.

Another approach is also very common, that is, to do a dark slot along the wall, arrange a wall lamp or lamp belt in the dark slot, and the light of the lamp belt is generally diffused down at the ceiling, forming a soft atmosphere of light. Wall lighting is used for facade texture material performance or relief lighting, the light is projected from top to bottom across the wall, and will form a bright spot along the wall to create a similar feeling of sunlight through the gap.

There is also a relatively complex approach, that is, the pipeline introduces natural light devices, which require special construction. The device system includes a light shield, a light guide tube and a diffuser. Natural light is introduced by a lens with high light transmittance installed on the roof, and then transmitted through a light guide tube, which is a tube with a highly reflective film inside the wall. The light is transmitted through continuous reflection in the tube wall, and finally diffused through an optical plate at the end of the room. This way of construction is more complex, affected by the environment, suitable for less important environmental lighting space. However, its biggest advantage is energy saving, and it can also achieve the effect of "seeing the light and not the lamp".
