Taking a technical approach, light sources
can be identified using the compass point directions of
North, East, South and West. Light from the north tends
to be cold and clear hence the need for energy efficient
products. On the other hand, light from the south is warm
and strong all year round, hence the need to use light-diffusing
window blinds e.g. vertical blinds. Diffusion is a bending
of the sunlight causing it to scatter and go in multiple
directions. Therefore the goal of diffusion in window
blinds is to copy the soft shadow-free effect of sunlight
through clouds. By using two-layered fabric the sunlight
shines on the first layer of fabric and shadows it but then
also diffuses it outwards to land on the second layer much
more uniformly. Eastern light is normally bright and warm
in the mornings hence need for vertical
blinds with UV protection. The afternoon western light
is normally hot and bright hence the need for light control
and light diffusing.
Another way to achieve the goals of day lighting is to redirect
and reflect the sunlight. This is what light-coloured blinds
and shutters do so well. By tilting the slats, vanes, or
louvers at the correct angles, light can be reflected to
walls and ceilings, and redirected deeper into the room.
With each redirection and reflection, the light is diffused
and softened.
With day lighting there is flow through
the windows of heat, solar energy and light. There is need
to control heat loss in winder and solar heat gain in summer,
which is best done using an opaque fabric. The honeycomb
sheer fabric works well in diffusing light for day lighting.
Vertical blinds
help control blinding light since they reduce, divert and
even completely block the rays of the sun. Depending on
the amount of light to let in you could choose from Sheer
Shades, Semi-Sheer Shades, Light-Filtering Shades and Room-darkening
/ Blackout Shades in decreasing order.
