Architecture is the art and science of designing buildings and structures. A wider definition would include within its scope also the design of the total built environment, from the macro level of town planning, urban design, and landscape architecture to the micro level of creating furniture. Architectural design usually must address both feasibility and cost for the builder, as well as the function and aesthetics for the user. Planned architecture often manipulates space, volume, texture, light, shadow, or abstract elements in order to achieve pleasing aesthetics. This distinguishes it from applied science or engineering, which usually concentrate more on the functional and feasibility aspects of the design of constructions or structures. In the field of building architecture, the skills demanded of an architect range from the more complex, such as for a hospital or a stadium, to the apparently simpler, such as planning residential houses. Many architectural works may be seen also as cultural and political symbols or works of art. The role of an architect, though changing, has been central to the successful design and implementation of pleasingly built environments in which people live. Architectural lighting design refers to design for lighting, as it implies to the built environment. Architectural lighting design requires consideration of the amount of functional light provided, the energy consumed, as well as the aesthetic impact supplied by the architectural lighting system. Some buildings, like surgical centers and sports facilities, are primarily concerned with providing the appropriate amount of light for the associated activities. Some buildings, like warehouses and office buildings are primarily concerned with saving money through the energy efficiency of the architectural lighting system. Other buildings, like casinos and theatres, are primarily concerned with enhancing the appearance and emotional impact of architecture through the architectural lighting systems. Therefore, it is important that the sciences of light production and photometrics are balanced with the artistic application of light as a medium in the built environment. These architectural lighting systems should ideally be integrated with day lighting systems. Factors involved in architectural lighting design are essentially the same as those involved in designing of buildings and structures.

An optical fiber is a glass or plastic fiber designed to guide light along its length by total internal reflection. Fiber optics is the branch of applied science and engineering concerned with such optical fibers. Optical fibers are widely used in fiber optic communication, which permits digital data transmission over longer distances and at higher data rates than electronic communication. They are also used to form sensors, and are used in a variety of other applications. Fibers are widely used in illumination applications. They are used as light guides in medical and other applications where bright light needs to be brought to a focus on a target without a clear line-of-sight path. In some buildings, optical fibers are used to route sunlight from the roof to other parts of the building. Optical fiber illumination is also used for decorative applications, including signs, art, and artificial Christmas trees. Many famous boutiques use optical fibers to illuminate their crystal showcases from many different angles while only employing one light source. The optical fiber is an intrinsic part of the light-transmitting concrete building product known as Litracon. Fiber optic lighting is the use of optical fibers as the main transmitters of light. Fiber optic lighting mainly employs a single light source connected with multiple optical fiber bundles. These bundles provide a similar amount of light from different angles. As a result, fiber optic lighting not only conserves light energy, but it also provides greater illumination through the same source of light. Fiber optic lighting is getting more popular, with fixtures mounted into the ceiling structure so as to appear flush with it. These fiber optic lighting systems can use narrow beam spotlights or wider-angle floodlights, both of which are bulbs having their own reflectors. There are also lights with internal reflectors designed to accept common lamps that are generally less costly than reflector lamps. Most of the optical fibers used in fiber optic lighting are multi-mode, cheap and quite resistant to environmental strains.

A light-emitting diode or LED is a semiconductor device that emits incoherent narrow-spectrum light when electrically biased in the forward direction. This effect is a form of electroluminescence. The color of the emitted light depends on the composition and condition of the semi conducting material used, and can be infrared, visible or near-ultraviolet. A LED is a unique type of semiconductor diode. Like a normal diode, it consists of a chip of semi conducting material impregnated or doped with impurities to create a p-n junction. As in other diodes, current flows easily from the p-side or anode, to the n-side or cathode, but not in the reverse direction. Electrons and electron-holes flow into the junction from electrodes with different voltages. When an electron meets a hole, it falls into a lower energy level, and releases energy in the form of a photon. The wavelength of the light emitted, and therefore its color, depends on the energy of the materials forming the junction. In silicon or germanium diodes, the electrons and holes recombine by a non-radiating transition, which produces no optical emission because these are indirect materials. The materials used for an LED have a direct band gap with energy corresponding to near-infrared, visible or near-ultraviolet light. Free standing LEDs are usually constantly illuminated when a current passes through them, but flashing LEDs are also available. Flashing LEDs resemble standard LEDs, but they contain a small chip inside that causes the LED to flash with a typical period of one second. This type of LED comes most commonly as red, yellow, or green. Most flashing LEDs emit light of a single wavelength, but multicolored flashing LEDs are available too. LED lighting has recently taken the lighting industry by storm, as it is available as colorful disco and flashing varieties. LED lighting is cheap and almost any light color can be obtained. Most commonly, LED lighting is used in clubs, bars and parties. Expensive LED lighting is used in hotels and shopping complexes. Overall, LED lighting is among the newest concepts of lighting and is growing tremendously because of newer demands for cheap and reliable lighting methods.
