How to achieve indirect lighting in interior design.
For our planet the sun is a major lighting source. The light
which we receive on earth varies in intensity and quantity
depending upon the geographical location on earth.
For normal human activities inside the building what we require
is indirect light. There is a major difference between direct
and indirect light. Direct light from the sun produces light in
high quantities but also generates a lot of heat, which may not
be required or at sometimes can be uncomfortable.
Indirect lighting produces a good quality diffused light by
eliminating the heat that's being produced from sunlight.
Interior designers always look for various ways that will
increase the chances of achieving good quality sunlight into a
room.
the basic principle behind indirect lighting is easy. Obstruct
the direct sunlight on a surface that will absorb the heat and
throw our or disperse the light alone uniformly inside the room.
This requires a good study of various light entry points of a
given room and selecting surfaces that will receive direct
sunlight. Then applying finishes to these materials that will
absorb the heat but at the same time reflect a lot of light to
the interiors.
There is a major challenge in doing this.
Let's say that I select a bedroom to be treated for indirect
lighting. I select a plane wall opposite or adjacent to the
window opening that will receive direct sunlight. If I paint the
wall with a bright color, it will definitely reflect the light
in the entire room, but at the same time create a "glare" that
can be quite uncomfortable for the users.
So just creating reflecting surfaces is not the solution. The
surfaces that will reflect the direct light and at the same time
won't produce a glare are recommended here.
This can be easily achieved using artificial lighting. The
greatest advantage of artificial lighting is that you can select
the number of light sources in the first place. Then light
sources can be very creatively be hidden using shaders and other
design elements, so that the light spots can be directed towards
reflective surfaces.
A very common use of this technique is, project the light spots
on a bright reflective ceiling and the ceiling will uniformly
disperse the light in the rest of the room. Projecting the light
on ceiling will eliminate the problem of causing glare, since
the ceiling is always above the normal eye level.
Using a centralized light source on the ceiling and throwing the
light on adjacent walls is also a good solution. This will also
save a lot of wiring lengths, cutting your cost in the fixing up
of the total electrical system.
A careful choice of reflective surfaces inside a room can
greatly enhance the light qualities in a room. In interiors
there are hundreds of objects that receive light. Objects such
as walls, furniture ceiling, floor will have a tendency to
reflect light away from them. Objects like windowpanes, glass
panels in the furniture will absorb or will allow the light to
pass away the light thought them b reducing the heat and
intensity of light.
That's why careful selection of materials during design stage
can cause a good lighting solution. Also the lighting solution
will differ from room to room depending upon which direction the
room faces outwards. For this the sun path must be taken into
consideration. By careful study of the sun path it will be easy
to decide the color schemes and finishes for satisfactory result
in indirect lighting.
I hope this article was helpful to everyone.
