Landscape lighting

  2. 2. LANDSCAPE LIGHTING*Landscape lighting has excessive potentialto enhance the landscape and providesmany benefits for both residential andcommercial applications.*Landscape lighting can add safety, security,ambiance, mood and drama to the outdoorenvironment. Limited only to the designersimagination, the practical functions andvarious mood effects of landscape lightingare endless.
  3. 3. 1 SAFETY. One of the primary functions of LANDSCAPEexterior lighting is to insure safe passage forpedestrians on steps, sidewalks, walkways or other LIGHTINGareas where aspects of the outdoor environmentmay become a hazard at night. Safety lightingtypically projects downward and never into oneseyes and is free from glare. 2SECURITY. Low levels of light evenly spread around the perimeter of buildings can act as a preventive to intruders and provide greater security than floods which create pools of light along with dark shadows where someone can hide. Light sources that emit low level light from the knee down silhouette prowlers and make them visible from every angle. 3AMBIANCE AND DRAMA. Beauty, hospitality and drama are enhanced by the proper selection and placement of landscape lights. Choosing focal points of architecture, art, unique features and landscape plant material can add night time drama to the landscape after the sun has set.
  4. 4. 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. *Choose pathway lights offering downlighting with emphasis placed on fixtures that incorporate diffused or shielded lamps. *Avoid lighting that shines in the eyes. Since path light fixtures become an integral part of the landscape during the day, attention should be paid to placement and daytime appearance. *Typical fixtures: mushrooms, tulip light, lantern, specialty lights
  5. 5. 2.Step / deck Lighting *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 3.underwater step and as a surface lights on vertical Lighting posts.*Underwater lighting highlights underwater *Typical fixtures: spot/accent light,plant material and captures light to show off specialty lightsdepth or imaginative design.* Illuminating water-bodies not only increasetheir attractiveness but also ensures safety indark.*Cascading fountains and falls reflect light intheir movement adding a visual perspective tothe sound of rippling or spraying water.
  6. 6. 4. UP Lighting 5. down Lighting* Uplighting means to light something *Mirroring the effect of the sun or the moon,from below. downlighting is the most natural form of landscape lighting.*Uplighting is rarely seen in nature yet *Choose fixtures that can easily be mountedthis effect is typically used to highlight on eaves and walls or suspended from treesthe trees, statues etc. and other elevated structures. *The Downlighting effect is used to provide* and to produce large shadows and general illumination for safety, security ordramatic facades or to “wash” walls with outdoor entertainment or it can be used tolight. focus on a singular object such as a statue or specimen tree.
  7. 7. 6. Architectural Lighting*The techniques of architecturallighting are used to emphasize thevariation in texture as well asarchitectural features in brick and stonework, soffit details and facade.*Architectural lighting can also be usedto enhance gateways, statues *Spotlighting or Highlighting * Silhouetting * Shadowing * Grazing Light Spotlighting or HighlightingThis effect utilizes a narrow focused, deep beam of light to accent or highlight a specificlandscape object creating nighttime main point. Uplighting, downlighting or any combinationcan be used to create a spotlighting effect; however, care should be given when spotlightingsince it has so much potential of ruining a subtle beauty and enhancement of the nightscape iftoo much light is introduced.
  8. 8. Silhouetting Silhouetting is created when the image of a distinctive plant,tree, statue or other landscape object is reflected against a wallor other vertical surface. Lights are placed behind the plantmaterial or object to and direct the light upward onto thebackdrop to create this dramatic effect. Shadowing 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. Grazing LightGrazing light is utilized to highlight and enhance the textures ofinteresting surfaces such as cobblestone, masonry, stucco ortree bark. Hooded fixtures with wide beam spread lamps areideal for this technique.
  9. 9. LIGHTING fixtures1. Solar Lights* Solar lights make use of tinyphoto voltaic cells (PV cells) orsolar powered cells to charge thebattery that is integrated intolighting fixtures. With PV panel* Most manufactures prefer toinstall PV cell into the lightingfixture itself. These can’t work ifthey are placed in shade.* Other solar landscaping modelstend to separate the PV panelfrom the lighting fixture. Thus thePV panel will be able to receivemaximum sunlight. Drawback isthat wire have to be buried. Without PV panel
  10. 10. 2. fluorescent Lights A long straight tube coated with phosphor containing low pressure mercury that produces white light.3. halogen Lights High pressure incandescent lamps containing halogen gases such as iodine or bromine allowing filament to be operated at higher temperatures.4. Luminaire A complete lighting unit consisting of a lamp, ballast as required with the parts designed to distribute the light, position and protect the lamp and connect them to power supply.
  11. 11. 5. neon Lights* Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that containrarefied neon or other gases.* Neon lights are a type of cold cathode gas-discharge light. A neon tube light is asealed glass tube with a metal electrode at each end, filled with one of a number ofgases at low pressure.*Neon lights were named for neon, a noble gas which gives off a popular red light, butother gases and chemicals are used to produce other colors, suchas helium (yellow), carbon dioxide (white), and mercury (blue). 6. Light emitting diodes (led) *Earlier only halogen or fluorescent lamps could provide the punch, color, and energy savings for certain landscape applications, LEDs are now available with these important attributes, as well as added benefits of very long life and durability. *Light emitting diodes (led) are tiny light bulbs without filament that are illuminated solely by the movements of electrons in a semiconductor material.
