Lighting

Refers to either artificial light sources such as lamps or to natural illumination of interiors from daylight. Lighting represents a major component of energy consumption, accounting for a significant part of all energy consumed worldwide. Artificial lighting is provided today by electric lights, but previously by Gas lighting, candles or oil lamps. Proper lighting can enhance task performance or aesthetics; while there can be energy wastage and adverse health effects of lighting. Indoor lighting is a form of fixture or furnishing, and a key part of interior design. Lighting can also be an intrinsic component of landscaping.

Fixtures

Lighting fixtures come in a wide variety of styles for various functions. Some are very plain and functional, while some are pieces of art in themselves. Nearly any material can be used, so long as it can tolerate the heat and is in keeping with safety codes.

Proper selection of fixtures is complicated by the requirement to minimize the veiling reflections off of printed material. Since the exact orientation of printed material may not be closed controlled, a visual comfort probability can be calculated for a given set of lighting fixtures.

Types

Lighting types are classified by intended use as general, localized, or task lighting, depending largely on the distribution of the light produced by the fixture.

  • General lighting fills in between the two and 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 (1-2 foot-candles) since pedestrians and motorists already used to the dark will need little light for crossing the area.
  • Task lighting is mainly functional and is usually the most concentrated, for purposes such as reading or inspection of materials. For example, reading poor-quality reproductions may require task lighting levels up to 1500 lux (150 foot-candles), and some inspection tasks or surgical procedures require even higher levels.
  • Accent lighting is mainly decorative, intended to highlight pictures, plants, or other elements of interior design or landscaping.

Methods

  • Down-lighting is most common, with fixtures on or recessed in the ceiling casting light downward. This tends to be the most used method, used in both offices and homes. Although it is easy to design it has dramatic problems with glare and excess energy consumption due to large number of fittings.
  • Up-lighting is less common, often used to bounce indirect light off of the ceiling and back down, a much more user friendly approach to lighting space than direct lighting.
  • Up-lighting turns the entire ceiling into the light source and can minimize disabling glare on computer displays and other dark glossy surfaces. It gives a more uniform presentation of the light output in operation.
  • Front lighting is also quite common, but tends to make the subject look flat as its casts almost no shadow. Lighting from the side is the less common, as it tends to produce glare near eye level. Backlighting either around or through an object is mainly for accent.

Forms of Lighting

include alcove lighting, which like most other up-lighting is indirect. This is often done with fluorescent lighting or rope light, or occasionally with neon lighting. It is a form of backlighting.

Soffit or close to wall lighting can be general or a decorative wall-wash, sometimes used to bring out texture (like stucco or plaster) on a wall, though this may also show its defects as well. The effect depends heavily on the exact type of lighting source used.

Recessed lighting (often called "pot lights" in Canada, "can lights" or 'high hats" in the U.S.) is popular, with fixtures mounted into the ceiling structure so as to appear flush with it. These down -lights can use narrow beam spotlights, or wider-angle floodlights, both of which are bulbs having their own reflectors. There are also down-lights with internal reflectors designed to accept common 'A' lamps (light bulbs) which are generally less costly than reflector lamps. Down-lights can be incandescent, fluorescent, HID (high intensity discharge) or LED, though only reflector incandescent or HID lamps are available in spot configuration.

Track lighting, invented by Lightolier, was popular at one point because it was much easier to install then recessed lighting, and individual fixtures are decorative and can be easily aimed at a wall. It has regained some popularity recently in low-voltage tracks, which often look nothing like their predecessors because they do not have the safety issues that line-voltage systems have, and are therefore less bulky and more ornamental in themselves. A master transformer feeds all of the fixtures on the track or rod with 12 or 24 volts, instead of each light fixture having its own line-to-low voltage transformer. There are traditional spots and floods, as well as other small hanging fixtures. A modified version of this is cable lighting, where lights are hung from or clipped to bare metal cables under tension.

A sconce is a wall-mounted fixture, particularly one that shines up and sometimes down as well. A touchier (tour-she-AIR or tour-SHARE) is an up-light intended for ambient lighting. It is typically a floor lamp but may be wall-mounted like a sconce.

The portable or table lamp is probably the most common fixture, found in every home and many offices. The standard lamp and shade that sits on a table is general lighting, while the desk lamp is considered task lighting. Magnifier lamps are also task lighting.

The illuminated ceiling was once popular in the 1960s and 1970s but fell out of favor after the 1980s. This uses diffuser panels hung like a suspended ceiling below fluorescent lights, and is considered general lighting. Other forms include neon, which is not usually intended to illuminate anything else, but to actually be an artwork in itself. This would probably fall under accent lighting, though in a dark nightclub it could be considered general lighting. Underwater accent lighting is also used for koi ponds, fountains, swimming pools and the like.

In a movie theatre each step in the aisles is usually marked with a row of small lights, for convenience and safety when the film has started, hence the other lights are off. Traditionally made up of small low wattage, low voltage lamps in a track or translucent tube, these are rapidly being replaced with LED based versions.


Design

Lighting design as it applies to the built environment, also known as 'architectural lighting design', is both a science and an art. Comprehensive lighting design requires consideration of the amount of functional light provided, the energy consumed, as well as the aesthetic impact supplied by the lighting system. Some buildings, like surgical centres and sports facilities, are primarily concerned with providing the appropriate amount of light for the associated task. Some buildings, like warehouses and office buildings, are primarily concerned with saving money through the energy efficiency of the lighting system. Other buildings, like casinos and theatres, are primarily concerned with enhancing the appearance and emotional impact of architecture through lighting systems. Therefore, it is important that the sciences of light production and luminaries photometric are balanced with the artistic application of light as a medium in our built environment. These electrical lighting systems should also consider the impacts of, and ideally be integrated with, day-lighting systems. Factors involved in lighting design are essentially the same as those discussed above in energy conservation analysis.

Mathematical modelling is normally used for complex lighting design, whereas, for simple configurations, tables and simple hand calculations can be used. Based on the positions and mounting heights of the fixtures, and their photometric characteristics, the proposed lighting layout can be checked for uniformity and quantity of illumination. For larger projects or those with irregular floor plans, lighting design software can be used. Each fixture has its location entered, and the reflectance of walls, ceiling, and floors can be entered. The computer program will then produce a set of contour charts overlaid on the project floor plan, showing the light level to be expected at the working height. More advanced programs can include the effect of light from windows or skylights, allowing further optimization of the operating cost of the lighting installation.

The Zonal Cavity Method is used as a basis for both hand, tabulated, and computer calculations. This method uses the reflectance coefficients of room surfaces to model the contribution to useful illumination at the working level of the room due to light reflected from the walls and the ceiling. Simplified photometric values are usually given by fixture manufacturers for use in this method.

Computer modelling of outdoor flood lighting usually proceeds directly from photometric data. The total lighting power of a lamp is divided into small solid angular regions. Each region is extended to the surface which is to be lit and the area calculated, giving the light power per unit of area. Where multiple lamps are used to illuminate the same area, each one's contribution is summed. Again the tabulated light levels (in lux or foot-candles) can be presented as contour lines of constant lighting value, overlaid on the project plan drawing. Hand calculations might only be required at a few points, but computer calculations allow a better estimate of the uniformity and lighting level.

Practical lighting design must take into account the gradual decrease in light levels from each lamp owing to lamp aging, lamp burnout, and dirt accumulation on fixture and lamp surfaces. Empirically-established depreciation factors are listed in lighting design handbooks.


Energy consumption

Artificial lighting consumes a significant part of all electrical energy consumed worldwide. In homes and offices from 20 to 50 percent of total energy consumed is due to lighting. Most importantly, for some buildings over 90 percent of lighting energy consumed can be an unnecessary expense through over-illumination (Hawke, 2000). Thus lighting represents a critical component of energy use today, especially in large office buildings where there are many alternatives for energy utilization in lighting. There are several strategies available to minimize energy requirements in any building:

  • Specification of illumination requirements for each given use area.
  • analysis of lighting quality to insure that adverse components of lighting (for example, glare or incorrect colour spectrum) are not biasing the design.
  • Integration of space planning and interior architecture (including choice of interior surfaces and room geometries) to lighting design.
  • Design of time of day use that does not expend unnecessary energy.
  • Selection of fixture and lamp types that reflect best available technology for energy conservation.
  • Training of building occupants to utilize lighting equipment in most efficient manner.
  • Maintenance of lighting systems to minimize energy wastage.

 


Health effects

It is valuable to provide the correct light intensity and colour spectrum for each task or environment. Otherwise, energy not only could be wasted but over-illumination can lead to adverse health and psychological effects.

Specification of illumination requirements is the basic concept of deciding how much illumination is required for a given task. Clearly, much less light is required to illuminate a hallway or bathroom compared to that needed for a word processing work station. Prior to 1970 (and too often even today), a lighting engineer would simply apply the same level of illumination design to all parts of the building without considering usage. Generally speaking, the energy expended is proportional to the design illumination level. For example, a lighting level of 80 foot-candles might be chosen for a work environment involving meeting rooms and conferences, whereas a level of 40 foot-candles could be selected for building hallways. If the hallway standard simply emulates the conference room needs, then twice the amount of energy will be consumed as is needed for hallways. Unfortunately, most of the lighting standards even today have been specified by industrial groups who manufacture and sell lighting, so that a historical commercial bias exists in designing most building lighting, especially for office and industrial settings. Beyond the energy factors being considered, it is important not to over-design illumination, lest adverse health effects such as headache frequency, stress, and increased blood pressure be induced by the higher lighting levels. In addition, glare or excess light can decrease worker efficiency (DiLouie, 2006).

Analysis of lighting quality particularly emphasizes use of natural lighting, but also considers spectral content if artificial light is to be used. Not only will greater reliance on natural light reduce energy consumption, but will favourably impact human health and performance. For example, it is clear that student test scores are improved for children who learn in the presence of greater natural light (Bain, 1997).

Advantages of fiber-optic lighting. Fiber-optic lighting can be installed almost anywhere. Basically, the light source, screws or adhesive screws or adhesives can be put in any convenient, safe and accessible location, thus simplifying maintenance. The fiber cables, or harnesses, along with the end fittings, or fixtures, can be installed fit almost anywhere. Usually, only the end fitting is visible in a system. Additionally, thin optical-fiber cabling can be retrofit into the ceiling or wall of an existing structure. The illuminator can have filters to remove most of the lamp's IR and UV energy, so an FO lighting system is ideal for illuminating materials such as textiles and paintings. Fiber-optic lighting is well-suited for historical structures when unnecessary penetration of the existing material is not allowed. Many original lighting fixtures can be retrofit with fiber-optics. Additionally, historic light levels and gaslight color rendering characteristics can be easily recreated. For museums with display cases that house historical artifacts, the advantages are apparent; no heat is generated within the case, and the display remains undisturbed when the light source is changed. The basic materials of a fiber-optic lighting tube are the core and the cladding. The core is the component that transmits the light. Tightly fitted around the core, the cladding is a thin material with a low refractive index. Light beams that graze the cladding at shallow angles are reflected back into the core. Fiber light, or fiber optics, is a way of lighting that becomes more and more popular due to the numerous applications related to this light. Nobody can really predict tomorrow’s applications of fiber light - new areas appear all along.

Kot prvo uporaba novih virov svetlobe oz. žarnic z velikim svetlobnim izkoristkom in dolgo življenjsko dobo. To pomeni, da svetila ob majhni moc(i oz. majhni porabi elektric(ne energije nudijo veliko svetlobe in dolge intervale med posameznimi vzdrževalnimi posegi. Skratka, skupaj minimalne obratovalne in vzdrževalne stroške. Seveda se tu ne sme pozabiti na kakovost svetil, ki morajo tako proizvedeno svetlobo posredovati na želeno mesto. Tu je bil v zadnem c(asu narejen še posebj velik korak v razvoju svetil, saj imajo sodobna svetila bistveno boljši svetlobno tehnic(ni izkoristek kot stara, npr. z debelo plastic(no opalno kapo, starejše rasterske svetilke in svetilke s starimi konvencionalnimi KVG predstikalnimi napravami. Prihrank pri zamenjavi starih svetil z novimi lahko pomeni tudi 100% prihranek pri elektriccni energiji. Seveda pa so tu še prednosti zaradi boljšega poc(utja strank in zaposlenih. Aktivne svetlobne stene in aktivni svetlobni stropi, ki s spreminjanjem intenzitete svetlobe in spreminjanjem barve svetlobe izredno privabljajo ljudi, zagotovijo atraktivnost prostora in predstavitev izdelka v zelo dinamiccni lucci. Lahko služijo kot vir neke splošne osvetlitve ali pa so le dodatni atraktivni element v prostoru. Uporaba opticcnih vlaken, s katerimi prav tako lahko spreminjamo intenziteto in barvo svetlobe. Ker optic(na vlakna ne oddajajo nikakršnih UV in IR žarkov in toplote je njihova uporaba še posebej primerna za osvetlitev tistih izdelkov, ki so obc(utljivi na toploto in segrevanje ( npr. nekaterih prehrambenih izdelkov, kozmetike ipd.) ter izdelkov obc(utljivih na obarvanje zaradi ultra violetnih UV in infra rdec(ih IR žarkov (npr. tkanine ipd.). Z opticcnimi vlakni se lahko dodatno poudari vhode in okolico trgovin in naredi atraktivno samo trgovino (npr. spreminjanje barv, zvezdno nebo ipd.). Uporaba svetil z LED tehniko. Ta vrsta svetil je zelo uporabna za orientacijo strank po trgovini, locitev posameznih blagovnih znamk med seboj in za ustvariti dodatno zanimivost v trgovini. Z LED svetili se lahko ustvari v trgovini dinamic(no vzdušje in igrivost. Njihova znacilnost je izredno majhna prikljuc(na moc( (od 1, 5 do 10W), dolga življenjska doba vira svetlobe (preko 50 000 ur do 100 000 oz. nekje do 11 let neprekinjenega delovanja) in barvna stabilnost tekom celotne obratovalne dobe. Zaradi dolge življenjske dobe, minimalne porabe elektric(ne energije in ker se praktic(no ne segrevajo so lahko vkljuc(ene stalno, tekom celotnega dneva. Svetila z LED tehniko lahko oddajajo svetlobo le v ene barvi (navadno: beli, modri, zeleni, rdecci ali rumeni), pri nekaterih tipih pa se lahko preliva preko 16 milijonov razlic(nih barv. Uporaba krmiljenja, preko katerega lahko krmilimo intenziteto in barvo osvetlitve, vklope in izklope posameznih svetil, tako da so izdelki tekom casa lahko osvetljeni iz razlicnih kotov, z razlicno barvo in intenziteto oz. jakostjo svetlobe. To pomeni, da so produkti lahko zjutraj osvetljeni drugacce kot opoldne, popoldne in zveccer zopet drugacce, primerno popoldanskemu oz. vecernemu casu. Seveda je cikel lahko tudi hitrejši, tako da se zaporedje npr. treh razlic(nih osvetlitev odvije npr. v treh minutah, pac( glede na efekt, ki se ga želi zagotoviti. Ta nacin osvetlitve je še posebej primeren za osvetlitve izložb.
