LIGHTING

Doorways

•A wall fixture is the obvious solution by a doorway for new construction •Concealing the light source particularly in the case of on an existing building where concealing cable may be difficult.

LIGHTING

Garage and Driveway

•Avoid glare to the driver pathway.•Well lit pathways.•If drive be tree lined, ‘moonlighting’ is an option

LIGHTING

Paths and Steps

•Designed to provide orientation.•Special care should be given to illuminating steps and level changes•Make user feel safe and comfortable

LIGHTING TECHNIQUES

1. Path Lighting*This technique is used

primarily for safety to highlight sidewalks, drives, or any path to ensure safe pedestrian passage at night.

*Typical fixtures: mushrooms,

tulip light, lantern, specialty lights

*Step lighting brings deck to life in

night and help us to navigate stairs safely during night.

*Its fixtures can be installed beneath

benches, as recessed light in the risers of step and as a surface lights on vertical posts.

*Underwater lighting highlights

underwater plant material and captures light to show off depth or imaginative design.

* It increases the aesthetic value and also

ensures safety.

2. Step/Deck Lighting

3. Underwater Lighting

4. UP Lighting

* Uplighting means to light something from below.

*Uplighting is rarely seen in nature yet this effect is typically used to highlight the trees, statues etc.

* and to produce large shadows and dramatic facades or to “wash” walls with light.

5. down Lighting

*Mirroring the effect of the sun or the moon, downlighting is the most natural

form of landscape lighting.

*The Downlighting effect is used to provide general illumination for safety, security or outdoor entertainment or it can be used to focus on a singular object such as a statue or specimen tree.

6. Architectural Lighting*The techniques of architectural lighting are used to emphasize the variation in texture as well as architectural features in brick and stone work, soffit details and facade.

*Architectural lighting can also be used to enhance gateways, statues

Architectural Lighting

*Spotlighting or Highlighting* Silhouette* Shadowing* Grazing Light

Grazing light is utilized to highlight and enhance the textures of interesting surfaces such as cobblestone, masonry, stucco or tree bark. Hooded fixtures with wide beam spread lamps are ideal for this technique.

This effect creates a visual similar to silhouetting; however; the fixture is positioned in front of the plant or object rather than behind it. Since the shadow of the object is often magnified the effect can be more dramatic than silhouetting.

Silhouetting is created when the image of a distinctive plant, tree, statue or other landscape object is reflected against a wall or other vertical surface. Lights are placed behind the plant material or object to and direct the light upward onto the backdrop to create this dramatic effect.

SHADOWS

•SHADOW THROUGH COLUMNS•As per Louis Kahn, Greek architecture introduces the concept of light, no-light through columns.•In ancient times columns showed people the day time through the length of shadows•In modern times it is used both for visual effect and light obstruction apart from structural element.

SHADOWS

•Mostly jalis are aesthetic usage of light and shadow•Jalis create patterned shadows over a building or on the exterior•In some cases they are used to bring in or allow partial light•Jalis reduces the intensity of light.

SHADOWS•LIGHT AND SHADOWS THROUGH TRANSLUCENT BARRIERS

•Light can travel through any medium. Therefore architects use this property of light to emphasize their architecture.•Translucent materials serve as a filter to the direct sunlight hence making the inner spaces pleasant and comfortable

•FOCUS OF LIGHT

SHADOWS

•Light shadows sometimes play as black and white/ good or bad•Walls or ceiling cut outs focuses the source of light •These pictures include usage of light and shadow as a form of giver for silent spaces•As per Louis Kahn- “Even a space intended to be dark should have just enough light from some mysterious opening to tell us how dark it really is.”

SHADOWS

•Apart from being structural elements arches also show light and shadow technique performed by architects•Shadows created by arches in some cases increases or decreases the depth of the path it follows•Louis Kahn–” The outside belongs to the sun and on the inside people live and work. In order to avoid protection from the sun I invented the idea of a deep intrados that protects the cool shadow.”

The Sun never knew how great it was until it hit the side of a building- Louis Khan
