Track lighting is a method of lighting where light fixtures are attached anywhere on a continuous track device which contains electrical conductors. [1] [2] This is in contrast to directly routing electrical wiring to individual light positions. Tracks can either be mounted to ceilings or walls, lengthwise down beams, or across rafters or joists.
Track lighting fixture – individual fixtures ("track heads") can be positioned anywhere along the track, which provides electric power. Under-cabinet light – mounted below kitchen wall cabinets. Display Case or Showcase light – shows merchandise on display within an enclosed case such as jewelry, grocery stores, and chain stores.
This revolutionary development provided a signal with a visible indication of over 1 mile (1.6 km) from the signal in broad daylight, when the signal was located on tangent track. The early color light signals were visible for only about half that distance (2,500 feet or 760 metres) while using about the same electrical current, then a major ...
Wavelight is a pace-setting system using a series of LED lights on the inside of an athletics track developed by Wavelight Technologies in Nijmegen, Netherlands. It has been allowed for use in competition by World Athletics since 2020, citing benefits to pacing and the spectator experience.
In optics, optical path length (OPL, denoted Λ in equations), also known as optical length or optical distance, is the length that light needs to travel through a vacuum to create the same phase difference as it would have when traveling through a given medium.
The minimum track spacing can be derived from the loading gauge. The European Berne Gauge has a width of 3,150 mm (10 ft 4 in). The minimal distance to structures on the side of the track is half of it but that is doubled again for double track lines. As the carriage can sway and bounce within the rail gauge, one adds 100 mm (3.9 in) and with a ...
The light characteristics of all light units are identical. In good visibility conditions the guidance information can be used at ranges up to 5 miles (8.0 km) by day and night. At night the light bars can be seen at ranges of at least 20 miles (32 km). PAPI systems are readily available from airfield lighting manufacturers worldwide.
A position light signal is one where the position of the lights, rather than their colour, determines the meaning. The aspect consists solely of a pattern of illuminated lights, which are all of the same colour. In many countries, small position light signals are used as shunting signals, while the main signals are of colour light form.
