“ExperiencingLight”

Our Philosophy of LIGHT

Light illuminates and makes visible. Light exposes and governs what we see. Light highlights and guides the eye. Light accentuates; it attracts; it manipulates; it instructs.

But true experience of beauty always must be functional, lest beauty be left without purpose. And beauty needs to be sustained, so forward thinking is pertinent. Only with those fulfilled can we have beauty for its own sake – something that makes people go “wow!” but also lets you sit quietly in one corner in utter bliss and comfort.

“Whatever beauty the eye beholds, it does so with light.”

Light does so many things, yet it works best behind the scenes. Which is why lighting so oft gets ignored. But without light, visual aesthetics is but an illusion, for whatever beauty the eye beholds, it does so with light.

“Experiencing Light”

PIC a. Experiencing Light Philosophy from Leuch’TechTM

PIC1. The simplest of furniture can be beautified by the right lighting arrangement and design.

The Art of Light

Lighting for Aesthetics

The saying “beauty lies in the eye of the beholder” is still arguable. However, the fact that beauty needs to be beheld by the eye is certainly true. For that reason alone, lighting plays a vital part in the beauty of our beloved home.

PIC2. An entrance during daytime; no artificial lighting

PIC3. The same entrance during nighttime, using lights to highlight the pillars and the texture of the wooden door.

When building a home, there are so many things to choose. The designer sofa, the artwork, the textures, the colors, the shapes of the tables. We want everything to be simply stunning.

And so we must aim to stun! Wash a little light to the textures, and you will add to its dimensions (Pic5, right). Shoot a beam up a tree, and you will

see it towering majestically in your garden (Pic4, right). Or, simply choose the right decorative pendant, and it will speak for itself (Pic6, right).

Let us transform your space. It can differentiate a house from a home, and make it truly a home sweet home!

Pendant: FOC

PIC4. Lighting up a tree makes it look taller, and accentuates the “nature” part of your home

PIC5. The wall comes alive just by wallwashing it with light

PIC6. The “behind-the-scene” lighting doing its job.

PIC7. A pendant from FOC gets its beauty by using light to bring out texture.

PIC8. What lighting can do. It transforms your architecture at night.

Perception & Spatial Manipulation

Good lighting manages both light and shadow to create an ambiance that fits the user’s needs. This section explains how we can use light and contrast to manipulate our sense of space.

The human eye interprets places that are brighter to mean that they are of farther distance, That is why highlighting certain areas of a room can make it look taller or wider.

In a narrow corridor, wallwashing would give the perception that it is more spacious than it actually

is.

Such spatial manipulation with light can give a room its added grandeur, or homeliness. The Pic (right) illustrates this theory in an actual project. In the two pictures of the exact setting, when the ceiling is lit up, the room looks taller.

PIC9. (By ERCO) Different settings create different perception of space.

PIC10. The images on the left and the right presents the exact same room photographed at the exact same scene. However, providing more light directed at the ceiling creates the illusion that it is higher.

Mood Setting & the ScienceOf Art

Different light color have differing side-effects to the human physiology. For consumers in Indonesia: Ever wonder why some supermarkets like Carrefour uses very white lights whilst others like Ranch Market uses warmer color? Would you agree that you would generally feel more energetic at the former and more relaxed at the latter?

The scientific explanation for this phenomenon is this: There is a tiny part of the brain called the Suprachiasmatic

Nucleus (SCN) located just above our optical nerves. This brain tissue captures and interprets the light captured by our retina, and tells the body to produce certain hormones or chemicals accordingly. This is called the body’s circadian rhythm, or for simplicity’s sake, the body-clock. A simplistic summary can be seen in PicX below.

When designing lighting for your home, we can recreate this body-clock by simulating the color of sunlight that best supports our activities.

For example, to achieve the highest level of productivity, we can simulate the color of sunlight at around 14:00-17:00, which would be “bluish-white” at around 5500K to 6500K.

Alternatively, to get a more relaxed atmosphere, we can simulate the color of

sunlight before our body stops producing melatonin (which makes us relaxed and sleepy), which would be “yellowish” at around 2700K-3000K.

The picture on the next page illustrates this very point. Which atmosphere do you like best? Or, mix and match to get a different feel in the different rooms of your house. Your choice.

PIC11. The Human Circadian Rhythm.

PIC12. Relaxed & Classy: A Residential Project using “Yellowish” light at average CCT of 2900K

PIC13. Modern & Energetic: A Residential Project using “Bluish-

White” light at average CCT of 6500K

Highlights – Working with other Objects of Art

This artwork with light is created by Allan D. Keller of DUA Lighting. It is a perfect illustration of what light can do to an object of art (or how light can be part of the object of art).

The above artwork is a 3D holographic image. The images are taken from three different viewpoints to illustrate what you will actually see when you circle around the object.

It gives the illusion that the

object follows us wherever we go. Directed light interacts with the texture to create shadow in the right places to give it a three-dimensional look.

PIC14. Three different viewpoint of the same artwork. Light makes it look alive!

PIC15. A Play of Light – Pendant utilizing Light to Bring out its Texture. From Freedom of Creation.

PIC16. Decorative Lights in the corridor. From Prandina.

PIC17. Uplights Used to Transformda Wall into a Work of Art by Accentuating its Uneven Texture.

Comfort

Just as you should not look directly into the sun, light works best when it remains hidden. Brightness without glare is one aspect of comfort.

Glare can be discomforting, even disabling. The above bedroom simply puts away the lights from where the eyes can see; thus creating a comfortable ambiance but with enough illuminance. The light under the bed-side table acts as a night-light – one

that provides light to the pathways but hide it away from the eyes.

Comfort is achieved by getting the right amount of light without the glaring effects.

PIC18. A Comfortable bedroom.

PIC19. Light is concealed, and downlights are placed where the eyesight would not view.

PIC20. Another case of concealed lights. Even the pendant above the dining table hides away its lamps.

Functionality& Benefit

IlluminationLevels

Now we will discuss the scientific and mathematical aspect of lighting. The rationale behind that is simple: The eye needs different illuminance levels for different tasks. This is important for health, savings and functionality.

The above artwork is a 3D holographic image. The images are taken from three different viewpoints to illustrate what you will actually see when you circle around the object.

It gives the illusion that the

object follows us wherever we go. Directed light interacts with the texture to create shadow in the right places to give it a three-dimensional look.

PIC21. Lighting Simulations – A Simulated Lighting Applications with exact lumen calculations using RELUXTM Lighting Design Tool.

PIC22. The Actual Result of the Above Design.

PIC23. Lighting Standards and Recommendations According to CIBSE.

Lighting Quality

Sunlight gives you perfect color rendering, at 100Ra. This is the benchmark to which all other light sources are measured. Good Color Rendering will make an object more radiant, more vibrant & therefore more

beautiful. The above pictures

show exactly its dramatic impact. In an exact setting, PIC24 uses Compact Fluorescent at Ra84 and PIC25 uses Low Pressure Sodium at Ra28. The result is self-explanatory.

PIC24. Road Lighting using 120Watt Clusterlite from MEGAMANTM.. Color Rendering (Ra) 87. Notice how clearly we can differentiate the colors.

PIC25. The same Road Lighting using 150Watt High Pressure Sodium. Color Rendering (Ra) 40. Notice how the color changes blue becoming white, red becoming orange etc..

Mere brightness is not enough, we must also look at the quality of the light. The terminology we are looking at is Color Rendering, measured in Ra. This indicates the capability of the light source to bring out the actual color of the object.

PIC26. Energy-Saving yet Functional: Megaman® R9 LED with CRI above 90 used to illuminate display of fruits. It

brings out its freshness; doesn’t attract flies (as it has no UV); and it emits no heat thereby preserving the fruits

longer.

Sustainability

Sustainable Design

Coming forward to the “Convenience” aspect of lighting and lighting design; we talk about Energy-saving, Maintenance, Ease of use and replacement. It should not only be beautiful, it should be easy to use and maintain.

Beauty should not be inconvenient, and convenience should not be ugly! Getting the best of both world is possible when you know the appropriate technology to be used for the particular application.

Both beauty and convenience can be achieved with the proper understanding of human behavior

and designing solutions around it. LEDs in a chandelier takes away its massive heat, bulb-replacement, and energy problems. The right downlighting can help reduce energy consumption for as much as 30%! Bringing luminaires further down can mean less energy needed – and all this is once for a lifetime solution!

PIC27. Chandeliers. Beautiful, but often unused because of excessive heat, difficult bulb-replacements, and the massive energy it consumes. Beauty should not be this inconvenient!

PIC28. (Top) One 6,5 * 7,5 * 3.1 (L*W*H) living room lit up with only 5 downlights of 13 watts each. This would normally be lit with at least 8 downlights at 18 watts each. With high LOR (Light Output Ratio) downlights, considerable savings is achieved; permanently.

PIC29. (Left) An office lit up with fluorescent pendants. Bringing the light down means lower wattage is needed. The use of indirect light sets the mood and atmosphere.

Choosing the Appropriate Technology

With so much hype being tossed around about the magic of LED, we may have forgotten that what is too good to be true probably isn’t. Marketing sometimes does its job irresponsibly – creating a demand that is unnecessary.

Many times, marketing tries to sell something that is utterly useless. Despite the many hypes in the market about the fabulousness of LED, the technology is relatively new, and no standards have yet been set (at the time of

writing) to differentiate good LED products from a bad one. And as you can see in a later section (p. XX), being uninformed can be very costly indeed.

PIC30. Megaman® LED for general lighting is one amongst many that offers multi-directional light. Without it, the application of LED for general lighting just doesn’t make any sense!

PIC31. Most LEDs in the market offer directional light; rendering reflectors in downligts useless, and hindering light from shining down from lamp shades. This is inefficient but expensive!

PIC32. (Top) The above shop – believe it or not – only uses Megaman®’s Compact Fluorescent Lamps. Not a single LED, halogen or halogen lamps. When the shop has no requirement for high contrasts, Compact Fluorescent Lamps does the job superbly with much lower investment cost.

PIC33. (Left) The shop uses a combination of fluorescent lamps for its general lighting and LED lamps from Megaman® for its focused lighting. It gives the shop a higher-class look, and greater contrast to guide the consumer eye.

Sensible energy-saving. This room, originally consumed over 3000 Watts for its lighting. By changing some of its applications to LED, it now uses only 320 Watt – a saving of almost 90%! Arwin, the lighting designer and also owner of the house said that the change from halogen technologies to LED made the magic possible.

The switch wasn’t without its challenge. “The Megaman LED performed much better at the green and blue parts of the spectrum, but not at its red part. I had to change the artwork on the wall, as well as the color of the sofa to ensure that the colors remain vibrant,” Arwin commented. “I deliberately chose the green apple, which is perfectly lit up by the LED. What made me extremely happy was that the resultant savings was so significant.”
