Lampshade
The lampshade ( ) is listed on a lamp (in everyday speech lamp is mounted) device for various purposes:
- to block the light that is too strong for the eye,
- focus the light on specific areas, e.g. B. the reading area in the living room,
- to reduce the influence of radiant heat from the lamps and
- to compensate for the predominant colors of a light source.
- Create atmosphere in the room.
- to look decorative even when the lamp is not lit.
Lampshades are used in modern architecture as a light object and as a luminaire that gives the room a pleasant atmosphere. Almost all materials and shapes can be used for a lampshade: fabric shades, lacquer shades, line lacquer shades, parchment shades, etc. Today there are also special glass fiber fabrics that are flame retardant and, for example, B. be used at airports.
There are hardly any limits to the imagination of shapes: cubic shapes, cylinders, composite shapes from different shades.
To achieve the first-mentioned purpose, one uses bell-, plate- or funnel-shaped lampshades made of frosted glass (formerly called Parisian lampshade), milk glass , mica , paper , textiles or even wrapped sisal cord .
For the second-mentioned purpose, lampshades are used in particular in work areas of offices, workshops and factories. Functionally designed shades are also common for glare lanterns and headlights .
Lampshades made from screen glass reduce the effects of the heat emitted by the lamps without noticeably weakening the light.
Since the eye cannot tolerate colored light well, light sources emitting colored light must be surrounded by a suitable lampshade in order to generate “warm” light. In general, umbrellas in the respective complementary colors are used for this .
