White Noise - A random audio signal with a flat power spectral density that contains noise at the same level at all frequencies. The signal's spectral density has equal power in any band and at any frequency in a . Used . given bandwidth. White noise is similar to white light which contains all frequencies. White noise is often used in the field of architectural acoustics to mask distracting or undesirable n. Used . oises in interior spaces....

Fresnel - Fresnels are typically 8-, 6- or 4-inch, referring to the diameter of the lens. This light is named after Augustin-Jean Fresnel who invented the distinctive Fresnel lens which has a 'stepped' appearan. Used . ce instead of the 'full' or 'smooth' appearance of other lenses. The stepped nature of the lens causes a corresponding pattern of circles of light, so Fresnel lenses are usually 'stippled' on. Used . the flat side. This pattern of small bumps helps to break up the light passing into the lens to smooth out its eventual pattern.

Fresnels use a spherical reflector, with the filament of the bulb ...

Address - In computer science, a memory address is a unique identifier for a memory location at which a CPU or other device can store a piece of data for later retrieval. In modern byte-addressable computers, e.

Indoor Architectural Lighting

Indoor architectural lighting is seen by its proponents as something of an art, as well as a science. Also called architectural lighting design, indoor architectural lighting is about carefully balancing the requirements of light in a building with the building’s aesthetics, and also the cost and energy efficiency of the indoor architectural lighting system. For example, in indoor hotel lighting or indoor museum lighting, it’s possible to analyze how much daylight the internal spaces of the building receive, using something called the Daylight Factor to calculate this. These calculations can be based on tabular data in smaller, simpler buildings, and then applied to its indoor architectural lighting design. However, if a specialist indoor architectural lighting design is required for indoor building lighting, then it’s better to use software programs or mathematical models to calculate the optimum amount of light that will be needed for the most aesthetically pleasing effect. Many types of lighting equipment can be used in indoor architectural lighting. One of the newest, but still not widespread is indoor LED lighting, which is slowly gaining popularity for its low cost and high energy efficiency. For now, LED lighting is not standard in indoor architectural lighting, as more conventional lighting systems are preferred. Indoor architectural lighting is often unique to each building, as a buildings furniture and the color of its walls and ceilings (and the materials) all effect the lighting. Rooms with walls and ceilings that are painted in dark colors, or have dark colored wall paper, seem to absorb the light more readily than light colored rooms, and so the light in the room will appear dimmer than it actually is. It also has the effect of making the room looks smaller in some circumstances. Indoor architectural lighting designers also need to take care of certain reflective surfaces in a room, such as its furnishings, which can cause undesired glare if they are too reflective.
