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.
