Color Shift

COLOR SHIFT

Defining Shadows and Darkness

“It is necessary to return to the point where the interplay of light and dark reveals forms, and in this way to bring richness back into architectural space. Yet, the richness and depth of darkness has disappeared from our consciousness, and the subtle nuances that light and darkness engender, their spatial resonance – these are almost forgotten. Today, when all is cast in homogenous light, I am committed to pursuing the interrelationship of light and darkness . Light, whose beauty within darkness is as of jewels that one might cup in one’s hands; light that, hollowing out darkness and piercing our bodies, blows life into ‘place’.”

– Tadao Ando (1990)

Impact of Temperature on Light

When fixtures and lighting systems are tested under the IEC 60598, the ambient temperature is kept close to 25 degree centigrade and 65% relative humidity. After injecting the right voltage, the fixture is kept burning for four hours. In this time the temperature rise of the various components used in the fitting would have stabilized, and the temperature rise recorded through the help of thermocouples fixed to the various parts of the fitting. From this set of data, the release of the fitting is decided.  If the fitting is found suitable for 25 deg. Ambient (Outdoor) and 35Deg. Ambient for indoor, it is cleared for sale, as the temperature in Europe never exceeds these temperatures. However, in other parts of the world, the temperatures are usually much higher.

  • Fixtures are currently tested between 20°c and 30°c which is not adequate.
  • Under the IEC 60598 [25°c, 65% RH], the fixture is lit for four hours until the temperature is stabilized.
  • If the fitting is found suitable for 25°c [outdoor] and 35°c [indoor] conditions, it is cleared for sale.
  • Europe rarely exceeds these conditions but other parts of the world do.

Impact of Humidity on Light

Some areas have almost 90% humidity through several months of the year. The humidity in the air coupled with water in the ground means that all components of a lighting system need to be addressed as a complete system to ensure proper functioning. The water/ humidity finds the weakest link in the system and creeps through to the other parts via capillary action which has an adverse impact on the functioning and life of the components.

Choice of hardware must also be informed by whether the environment is near the ocean, as the salines will then have an adverse impact on the componentry.

  • Humidity coupled with ground water means that all components of a lighting system must be addressed
  • Water finds the weakest link in the system and seeps through via capillary action
  • Alia Diwa Resort Goa:
    • Wiring processes: use of glands, mastic tapes and silicone fills essential to keep humidity and ground water out
    • Salinity has an adverse impact on the componentry.

Symbolism of Light

Apart from the philosophical connotations that light posses, it also is utilized throughout many cultures around the world as both a literal and metaphorical symbol. The Yin and Yang is one of the best examples of this concept as discussed previously, but there are many others as well. When different world religions are analyzed from a lighting perspective, it can be seen that different cultures and religions view light through its symbolic nature. Several global holidays use the symbolism of light as a marking of celebration. Following are some holidays which use light for its symbolism.

In Buddhism light is used as a symbol in the ritual of the eight offerings where it plays a central role. Apart from Buddhism, Islam also uses light as a symbol, most visually through its interpretation of ‘the lamp’ in the Qur’an;

“God is the Light of the heavens and the earth.
The Parable of His Light is as if there were a Niche and within it a Lamp
the Lamp enclosed in Glass: the glass as it were a brilliant star
Lit from a blessed Tree, an Olive, neither of the east nor of the West,
whose oil is well-nigh luminous, though fire scarce touched it
Light upon Light! God doth guide whom He will to His Light
God doth set forth Parables for men: and God doth know all things.”

Another symbol commonly used if the candlelight as a symbol of wisdom. In our physical world we see things through the medium of light. If we do not have sun or electric light, this world is so dark that we cannot see anything. In our spiritual and mental world the physical light cannot help us to see. We see only through wisdom. We may stumble many times in daily life because we lack ‘light’ and ‘wisdom’. Light in this sense can also be translated into a more eastern sensibility through the term ‘enlightenment’. Jung writes in the foreword to An Introduction to Japanese Buddhism;

“This strange perception is called Satori, and may be translated as “Enlightenment”. Suzuki says (see page 95), “Satori is the raison d’etre of Zen, and without it there is no Zen.” It should not be too difficult for the Western mind to grasp what a mystic understands by “enlightenment”, or what is known as “enlightenment” in religious parlance.”

Religion:

• When different world religions are analyzed from a lighting perspective, different cultures and religions view light for its symbolic nature. Several of the global holidays use the symbolism of light celebration. In the images that will be shared in the talk, the following are the different holidays which use light for its symbolism.

Symbols of Light:

• Obon Festival [Japan]

• Hanukkah

• Loy Krathong [Thailand]

• Diwali

• Paper Lantern Festival [Singapore]

• Christmas

• Ramadan

• Cathedral of Light 1936

• Tribute in Light, New York

• Symphony of Lights, Hong Kong

• SRBS Bridge, Dubai
