Light & Illumination

Problem

Uniform illumination—the sweetheart of the lighting engineers—serves no useful purpose whatsoever. In fact, it destroys the social nature of space, and makes people feel disoriented and unbounded.

Solution

Place the lights low, and apart, to form individual pools of light which encompass chairs and tables like bubbles to reinforce the social character of the spaces which they form. Remember that you can’t have pools of light without the darker places in between.

Problem

When they have a choice, people will always gravitate to those rooms which have light on two sides, and leave the rooms which are lit only from one side unused and empty.

Solution

Locate each room so that it has outdoor space outside it on at least two sides, and then place windows in these outdoor walls so that natural light falls into every room from more than one direction.

"If what one finds is made of pure matter, it will never spoil. And one can always come back. If what you had found was only a moment of light, like the explosion of a star, you would find nothing on your return."

In between these two extremes is a room with three constructions by Robert Irwin. These can be read as individual works of art but their function here is primarily that of creating a climate of fastidious ambiguity. Light turns into a new kind of material; new kinds of material are fused into light; a vaporous middle-world stands midway between total black (Bell) and total white (Wheeler)

Le Corbusier, the greatest architect of the last century, noted that 'architecture is the learned game, correct and magnificent, of forms assembled in light', demonstrating to what extent light has been prioritized in the Western tradition. Tanizaki, on the other hand, spoke of the important of shadows, of extended eaves. Rather than the light that shines directly into a room, he praised the soft light that penetrates a space after being reflected off the floor, and again from the ceiling.

...In Japanese architecture, the gentle light that passes through shoji screens serves a key purpose. It reaches right to the back of the room, so that the space feels bright, even without the aid of artificial light. The soft light filtering through the white film at Takanawa Gateway Station represents a form of light that was forgotten about by Japanese Modernism.

Irwin has explained that he decided to use the fluorescent tubes in the "dumbest" way possible, but, as one critic cautioned, "dumb, it turns out, has a special meaning for him: It's a form so simple that you end up not paying attention to it as a form." Irwin's interest was, rather, in the range of light, color, reflection, and shadow interaction made possible by combining tubes with different hues and finishes by wrapping them with theatrical gels.

In addition to managing the flow of people in the spaces of the museum in order to maximize freedom of movement and choice, Irwin also modified the industrial window grids to create perceptual ambiguity, placing transparent glass in the inner four panes while using frosted glass for the outer panes. With this, Irwin solved the problem of either having the windows become a wall of glaring light, if all transparent glass was used, or having them become a claustrophobic muffling of space, if all frosted glass was used. Irwin's windows catch the eye in a back and forth oscillation between distant and proximal focus.

Darkness cannot say: “I precede the coming light”, but there is a sense in which light can say, “Darkness preceded me”.

Doubtless there is an event, X, in the future, by reference to which we may say that we are at present in a category of Not-X, but until X occurs, the category of Not-X is without reality. Only X can give reality to Not-X; that is to say, Not-Being depends for its reality upon Being. In this way we may faintly see how the creation of Time may be said automatically to create a time when Time was not, and how the Being of God can be said to create a Not-Being that is not God.

Like a forest or a garden or a field, an honest page of letters can absorb – and will repay – all the attention it is given. Much type now, however, is delivered to computer screens. It is a good deal harder to make text truly legible on screen than to render streaming video. Both fine technology and great restraint are required to make the screen as restful to the eyes as ordinary paper.

The underlying problem is that the screen mimics the sky instead of the earth. It bombards the eye with light instead of waiting to repay the gift of vision – like the petals of a flower, or the face of a thinking animal, or a well-made typographic page. And we read the screen the way we read the sky: in quick sweeps, guessing at the weather from the changing shapes of clouds, or in magnified small bits, like astronomers studying details. We look to it for clues and revelations more than wisdom. This makes it an attractive place for the open storage of pulverized information – names, dates, or library call numbers, for instance – but not so good a place for thoughtful text.

Searle: In psych tests on deep space, I ran a number of sensory deprivation trials, tested in total darkness, on floatation tanks - and the point about darkness is, you float in it. You and the darkness are distinct from each other because darkness is an absence of something, it's a vacuum. But total light envelops you. It becomes you.

When people say that white walls are cold and characterless, I wonder whether they have ever stopped to look at one. It's not just about the drama of light and shadow, although I love the fragment of the ghost chair in this picture, but the way the smallest nuances of texture and tone come alive in certain conditions.

How much more mysterious and inviting is the street of an old town with its alternating realms of darkness and light than are the brightly and evenly lit streets of today! Homogenous bright light paralyzes the imagination in the same way that homogenization of space weakens the experience of being, and wipes away the sense of place. The human eye is most perfectly tuned for twilight rather than bright daylight.

In today's architectural practice, light is regrettably often treated merely as a quantitative phenomenon; design regulations and standards specify required minimum level of illumination and window sizes, but they do not define any maximum levels of luminance, or desired qualities of light, such as its orientation, temperature, color, or reflectedness.

Daylight should not tyrannize architecture. As with so many aspects of the design of the city, light is something that should be available in a variety of modulations and susceptible to a variety of controls. However, the prejudice must always be for access.

Street lights can be like that famous stone that falls in the desert where there are no ears to hear. Does it make a noise? Without effective eyes to see, does a light cast light? Not for practical purposes.

Problem

In a building with uniform light level, there are few “places” which function as effective settings for human events. This happens because, to a large extent, the places which make effective settings are defined by light.

Solution

Create alternating areas of light and dark throughout the building, in such a way that people naturally walk toward the light, whenever they are going to important places: seats, entrances, stairs, passages, places of special beauty, and make other areas darker, to increase the contrast.

If you are there at sunset, as are the scientists every day, you see the most magical of transformations: the golden glow that fills the sky to the west is first reflected in the water of the ocean and then shoots like a line of fire up through the gathering darkness of the plaza's stone floor, to reach its source in the cubic fountain. The court is breathtaking in its sublime power, opening at the edge of the continent to the Pacific Ocean and framing the light blue-on-dark-blue horizon line of the sea and sky.

And it came to pass that AC learned how to reverse the direction of entropy. But there was now no man to whom AC might give the answer of the last question. No matter. The answer – by demonstration – would take care of that, too.

For another timeless interval, AC thought how best to do this. Carefully, AC organized the program.

The consciousness of AC encompassed all of what had once been a Universe and brooded over what was now Chaos. Step by step, it must be done.

And AC said, "LET THERE BE LIGHT!"

And there was light.

If you look for the light,
you can often find it.
But if you look for the dark,
that is all you will ever see.

— Uncle Iroh

The bright sun was extinguish'd, and the stars
Did wander darkling in the eternal space,
Rayless, and pathless, and the icy earth
Swung blind and blackening in the moonless air;
Morn came and went—and came, and brought no day.

Yamamoto Sanehiko, president of the Kaizo publishing house, told me of something that happened when he escorted Dr. Einstein on a trip to Kyoto. As the train neared Ishiyama, Einstein looked out the window and remarked, "Now that is terribly wasteful." When asked what he meant, Einstein pointed to an electric lamp burning in broad daylight.

And the truth of the matter is that Japan wastes more electric light than any Western country except America.

I could not know that even then the little light was being drawn irresistibly into the great soundless whirl of darkness and that I was watching a light that was destined soon to blink out and disappear.

And here we come back to that forgotten, outcast word, the soul.

Indeed, the soul possesses an inner light, the light that an inner vision knows and expresses in the world of brilliant colors, in the world of sunlight.

For those who've never experienced a sunrise in the rural Midwest, it's roughly as soft and romantic as someone's abruptly hitting the lights in a dark room. This is because the land is so flat that there is nothing to impede or gradualize the sun's appearance. It's just all of a sudden there.
