Herunterladen, um offline zu lesen

Lightning or illumination is the deliberate use of light to achieve a practical or aesthetic effect
.
Landscape lighting or garden lighting refers to the use of outdoor illumination of private gardens and public landscapes; for the enhancement and purposes of safety, night-time aesthetics, accessibility, security, recreation and sports, and social and event uses
to promote observation and experience of the site against the night sky
Street lightning was began approx 300 years ago.
These were oil lamps placed on wooden poles.
By the 18th century oil lamp were still used but the poles and lamps were made of cast iron fixtures .
The beginning of 19th century saw gas lamps come in to use .
By the 20th century electric lamps were in wide use .Metal halide lamps are commonly used in streetlights, parking lot lights, and stadium lights.
They are very bright and contribute to a lot of light pollutionFloodlights are broad-beamed, high-intensity artificial lights.
Landscape lighting showcases plants, trees, shrubs, and flowers. Small spotlights and well lights
Specialised lighting are those lighting which are positioned in the right place to get maximum impact.
It can be used in landscape , outdoor and garden lighting designs in fountains , swimming pools etc.

  1. 1. LIGHTNING (OUTDOOR AND SPECIALIZED )
  2. 2. WHAT IS LIGHTNING ?? •Lightning or illumination is the deliberate use of light to achieve a practical or aesthetic effect. •Proper lightning can enhance task performance, improve the appearance of an area , or have positive psychological effects on occupants .
  3. 3. what is outdoor lightning ?? Landscape lighting or garden lighting refers to the use of outdoor illumination of private gardens and public landscapes; for the enhancement and purposes of safety, night-time aesthetics, accessibility, security, recreation and sports, and social and event uses .
  4. 4. HISTORY •Street lightning was began approx 300 years ago. •These were oil lamps placed on wooden poles. •By the 18th century oil lamp were still used but the poles and lamps were made of cast iron fixtures . •The beginning of 19th century saw gas lamps come in to use . •By the 20th century electric lamps were in wide use .
  5. 5. WHAT IS OUTDOOR LIGHTNING NOW ?? •Street lightning •stadium •Porch lightning •Parking lots •Road lightning •Landscaping •Buildings •Pedestrian and bicycling pathways
  6. 6. •to promote observation and experience of the site against the night sky •to give the building an added dimension which will enhance its key architectural elements as well as its social and historical significance •to improve the quality of the nocturnal environment by promoting safety, ie avoidance of trip hazards •to enhance night-time orientation and use, which could potentially benefit the local economy PURPOSE OF OUTDOOR LIGHTNING
  7. 7. •Used mainly for large area applications •Provide higher efficacy and longer service life •Most common types are mercury vapor (MV), metal halide (MH), and high-pressure sodium (HPS) –Metal Halide – 100/lumens per watt –HPS – up to 150/lumens per watt –MV – being phased out High-Intensity Discharge
  8. 8. •Also considered a high intensity discharge lamp, but it has some unique characteristics. • While this light is fairly efficient, it takes several minutes for the bulb to turn on. •The light is very yellow-orange •Most efficient form of artificial lighting •Maintain their light output better than other lamps. •Produces up to 200/lumens per watt Low-Pressure Sodium
  9. 9. •The high pressure sodium lamp (HPS) is the most commonly used street light throughout the world. •It produces light by running electricity through a mixture of gases, which produces light. •The lamp itself is preferred because it requires little maintenance. • These lamps are fairly efficient. •They take a while to turn on completely and produce a yellow- orange glow. High Pressure Sodium (HPS)
  10. 10. FLOOD LIGHTNING ?? •Floodlights are broad-beamed, high-intensity artificial lights. • They are often used to illuminate outdoor playing fields while an outdoor sports event is being held during low-light conditions.
  11. 11. Metal halide lamps are commonly used in streetlights, parking lot lights, and stadium lights. They are very bright and contribute to a lot of light pollution . They are fairly efficient. They produce very white light and have good color rendition, meaning that objects under these lights look their true color Metal Halide:
  12. 12. Deck or step lights illuminate walkways, sidewalks, driveways, and pool edges. Installed low to the ground, path lights literally light the way for safety and security. Ideally you should choose a path light that is covered on the top so that the light will spread evenly along the ground, rather than create a glare DECK AND STEP LIGHTS
  13. 13. Solar deck lighting creates a dim, soft glow ideal for complementing a low- voltage system, and provides ambient lighting at night where your deck gets lots of sunlight throughout the day. Charging and run times depend on the season and location, with greater exposure to direct sunlight producing longer run times at night. Solar deck lighting is also a great solution for those who want a little extra light without setting up wiring SOLAR DECK LIGHTNING...
  14. 14. LED DECK LIGHTNING ..... •LED deck lighting offers a high-tech way to illuminate your property while also staying eco- friendly. •LED lights are an efficient light source that remains cool to the touch, reduces energy costs, and yield a longer and more reliable lighting source than solar lighting.
  15. 15. Cove lighting can be used to highlight swimming pools, fountains, outdoor living areas, landscaping, outdoor architectural features, signs, and outdoor walkways. Hidden strips, often containing long- lasting LED bulbs, allow for endless possibilities COVE LIGHTING
  16. 16. LANDSCAPE LIGHTNING Landscape lighting showcases plants, trees, shrubs, and flowers. Small spotlights and well lights (which require digging a hole so that the light will sit flush with the ground) are common for landscape lighting as they do not compete with plants for attention. Landscape lights can also be used to highlight architectural features like columns. Most landscape lights can be used in both capacities.
  17. 17. SPOTLIGHT WELL LIGHT
  18. 18. *Mirroring the effect of the sun or the moon, downlighting is the most natural form of landscape lighting. *Choose fixtures that can easily be mounted on eaves and walls or suspended from trees and other elevated structures. *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. * 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. UP LIGHTNING DOWN LIGHTNING
  19. 19. Dimmers - Light dimmers adjust the level of illumination depending on the traffic. Dimmers help with energy conservation and aid in your energy savings at home Dimmers are compatible with flush mounts, pendants, and lamps. motor detectors- Motion sensors activate the light fixture when movement is perceived. Motion detectors add an element of surprise and are compatible with floodlights, landscape path lights, and surface-mounted lights.
  20. 20. Photocells - Photocells automatically turn light fixtures on when it’s dark despite the time of day. Photocells are paired with a time switch to turn the lights on at dusk and turn off the lights at a specific time • Photocells should be placed where they are not affected by ambient lighting Time Switches - Timers are designed to turn light fixtures on and off at specific times, regardless of whether or not the light is necessary. Time switches work with floodlights, landscape path lights, roadway lights, surface-mounted lights, and post-mounted lights
