2. INTRODUCTION
 Light is the soul of architecture design.
 Light allows us to see, to know where we are
and what around us.
 Beyond exposing things to view and feel, light
models those objects to enhance visual and
to help us define the physical world.
 Nothing would be visible without light, light
also makes it possible to express and show to
the mind's eye things that eludes the physical
one.
 To redefine the relationships of people with
the environment and with themselves.
 It is divided into natural light and artificial light
 Natural light is a gift of nature.
 Civilized man learns to use artificial light
sources which free him from total dependence
on daylight.
 Artificial light is seeing both during the day as
well as after dark.

3. RELATION BETWEEN LIGHT SPACE AND HUMAN
 Light is fundamental for space and
essential for human well-being and it
is the success of any building.
 Light quality affects human
behaviour, health, comfort and mood.
 "Space and light and order. Those
are the things that men need just
as much as they need bread or a
place to sleep“ -Le Corbusier,
August27,1965
 Light, space and human they effect
and work with each other.
 Space needs light to illuminate; light
needs space to receive it, light within
the space change human experience.

4. NATURAL LIGHT AND ARCHITECTURE
 Natural light keeps changing through
times.
 However, architects cannot control
natural light, which from morning to
night, day after day changes.
 Its existence gives life to space,
modeling the spatial sensibility.
 Natural light for the space, like the air
for life, these two have symbiotic
relationship.
 Natural light into interior design have
many positive effects, including the
considerable financial savings in
energy.
 Natural light is considered a beneficial
design for many reasons: human
health, comfort and satisfaction,
energy conservation, view.

5. LIGHTNING
 Lighting within the indoor
environment can be considered to
have three basic purposes:
 To enable the occupants to work
and move about in safety.
 To enable tasks to be performed.
 To make the interior look pleasant.
 There are two principle ways in
which a building can be lit.-
Naturally - by daylight received from
the sky.
Artificially - by electric lamps or
other artificial light sources.
Natural lightning
Artificial lightning

6. NATURAL LIGHTNING
 Lighting or illumination is the
deliberate use of light to achieve a
practical or aesthetic effect.
 Lighting includes the use of both
artificial light as well as natural
illumination by capturing daylight.
 Daylight as two distinct sources of
light:
 Sunlight – That part of solar
radiation that reaches the earth’s
surface as parallel rays after
selective attenuation by the
atmosphere.
 Skylight – That part of solar
radiation that reaches the earth’s
surface as a result of scattering in
the atmosphere.
 Sunlight and skylight may therefore
be considered as the direct and
diffuse
 components of daylight.
Skylight
Sunlight

7. ARTIFICIAL LIGHTNING

natural light.
