Lighting Lighting Presentation Transcript

  • LIGHTING Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of artificial light sources like lamps and other light fixtures. Proper lighting can enhance task performance, improve the appearance of an area, or have positive Psychological Effects on Occupants. Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an essential component of landscape projects.
  • GENERAL RULES • If your room faces NORTH: you won't get much direct sunlight but a cold, harsh light. Artists choose to have their studios facing north as you get a truer colour rendition. • If your room faces EAST: you'll have bright light first thing in the morning, with long shadows and will lose the sun later in the day. • If your room faces SOUTH: you'll have a warm light all day, although it changes throughout the day and year. The midday sun will tend to be so bright it will flatten everything out. • If your room faces WEST: you'll get sunlight at the hottest part of the day, which can cause glare. Then in the late afternoon you'll get long shadows and a softer light.
  • POINTS TO BE REMEMBERED • North and East facing rooms - need to maximise the quality of light and may need artificial lighting and measures to control glare. • South and West facing rooms - generally receive lots of light, which needs controlling.
  • TYPES OF LIGHTING Lighting is classified as general, accent, or task lighting, depending largely on the distribution of the light produced by the fixture. • Task lighting is mainly functional and is usually the most concentrated, used for purposes such as reading or inspection of materials.
  • TASK LIGHTING • Applications Mostly found in residential and commercial settings. They may have special features allowing it to be repositioned or adjusted for reading or other tasks, or to create a particular lighting ambiance, as in the corner of a living room. A folding tripod base facilitates storage or repositioning, while an adjustable arm can be used to direct the light onto seating or working areas. • Types Stainless steel, aluminium, cast iron and other materials are used to make these lamps. Base forms include tripod or pedestal styles. • Price Starts from Rs.800 and the price goes high according to the design.
  • ACCENT LIGHTING • Accent lighting is mainly decorative, intended to highlight pictures, plants, or other elements of interior design or landscaping.
  • • Several EMTEQ LED lighting products can function as accent lighting in your aircraft, including LED flexible strip lighting, LED curved wash lighting, LED spot lighting and LED vanity lighting. • Accent lighting is designed to be robust and functional yet attractive and as inconspicuous or noticeable as desired. • Accent lighting can be installed around seat bases, toe kicks, vanities and dropped aisles, among many other areas in the aircraft. • Products are economical and are perfect for installation. • Price starts from Rs.1000.
  • GENERAL/AMBIENT LIGHTING • General lighting or ambient light is intended for general illumination of an area. Indoors, this would be a basic lamp on a table or floor, or a fixture on the ceiling. Outdoors, general lighting for a parking lot may be as low as 10-20 lux since pedestrians and motorists already used to the dark will need little light for crossing the area.
  • • Applications Luminus has developed the XNOVA line of LEDs for professional and general lighting to enable further adoption of solid-state lighting by providing customers with outstanding technical performance and superior value. The XNOVA product line consists of a family of chip-on-board (COB) arrays and emitter products designed to provide best in class LED sources for applications including professional lighting fixtures and replacement lamps. Exceptional efficacy, colour quality and reliability are hallmarks of XNOVA technology with performance leading today’s top-tier LED suppliers. • Technologies and Price usually starts from Rs.3000 and the next depends on designs of lights and material used but they are economical.
  • COVE LIGHTING • Cove lighting is a form of indirect lighting built into ledges, recesses, or valences in a ceiling or high on the walls of a room. It directs light up towards the ceiling and down adjacent walls. • It may be used as primary lighting, or for aesthetic accent, especially to highlight decorative ceilings. • Cove lighting is valued because it hides the fixtures, and because it provides a very even, warm light. TYPES One method of installing cove lighting is by using T5 fluorescent tubes. T5 luminaires are an energy-efficient alternative as they save on materials. An even better energy-efficient alternative is to use LED strips, mounted on an aluminium profiles for optimum heat dissipation, with prismatic covers. With a dimming controller, the cove lighting can be dimmed. A wide range of LEDs are available.
  • Installation Lighting specialists recommend installing cove lighting at least 18 inches from the ceiling and 6 feet 8 inches from the floor. In kitchens, cove lights can be installed on the top of kitchen cabinets.
  • CHANDELIER A chandelier is a decorative ceiling-mounted light fixture. Chandeliers are often ornate, and normally use lamps hung from the ceiling. Crystal chandeliers have more or less complex arrays of crystal prisms to illuminate a room with refracted light. • PRICE STARTS FROM Rs.5000 AND THE REST DEPENDS ON DESIGN AND THE MATERIAL USED IN IT. • NEEDS MAINTAINANCE
  • UNDERWATER ACCENT LIGHTS Underwater Accent Lighting is also used for koi ponds, fountains, swimming pools and the like.
  • A lamp is a replaceable component which is designed to produce light from electricity. These components usually have a base of ceramic, metal, glass or plastic, which makes an electrical connection in the socket of a light fixture. This connection may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap. Lamp types include: Ballast Fluorescent Light Halogen Neon Light emitting diodes(LED) Compact fluorescent lamps
  • LED LIGHTS A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. ECONOMICAL AND DURABLE
  • CFL BULBS A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp, some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp. • CFL’s ARE ECONOMICAL • EASY TO INSTALL • ZERO MAINTAINANCE • EASILY AVAILABLE • PRICE STARTS FROM Rs.150 ONWARDS Incandescent Lamp CFL
  • DIMMERS Dimmers are devices used to vary the brightness of a light. By decreasing or increasing the RMS voltage and, hence, the mean power to the lamp, it is possible to vary the intensity of the light output. Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control light output from resistive incandescent, halogen, and (more recently) compact fluorescent lights (CFLs) and light-emitting diodes (LEDs). More specialized equipment is needed to dim fluorescent, mercury vapor, solid state and other arc lighting.
  • FLOODLIGHTS Floodlights can be used to illuminate outdoor playing fields or work zones during night-time hours. The most common type of floodlights are metal halide and high pressure sodium lights. • PRICE-Rs.2500
  • TUBE LIGHTS Light tubes or light pipes are physical structures used for transporting or distributing natural or artificial light for the purpose of illumination, and are examples of optical waveguides. Light pipes may be divided into two broad categories: Hollow structures that contain the light with a reflective lining, and Transparent solids that contain the light by total internal reflection. Generally speaking, a light pipe or light tube may refer to: A tube or pipe for transport of light to another location, minimizing the loss of light, a transparent tube or pipe for distribution of light over its length, either for equidistribution along the entire length or for controlled light leakage.
