Applied Energy, 2004
Abstract Light pipes (such as tubular lighting) are simple structures that allow the transmission of daylight from outside to inside a room. They are an increasingly popular product, with CIBSE Building Journal (September 2003) stating that there are now an estimated three million pipes installed throughout the globe.

Light pipe for high intensity laser pulses
Physical Review Letters, 1993Optical guiding of intense laser pulses over a distance in excess of 20 Rayleigh lengths has recently been demonstrated1 using a two pulse technique. The first pulse prepares a shock-driven, axially extended radial electron density profile which guides a second pulse, injected after an optimum delay which increases with mass of the plasma ions.

Right angle bends in light pipes: analysis
Applied Optics, 1976An expression for the fraction of incident radiation transmitted by a right angle bend in a rectangular light pipe is derived. This expression is used to show that, in a planar light pipe structure with right angle bends, light attenuation is due only to reflection losses at the walls if the launching angle is 45 degrees .

Solar Energy, 2010
An expression is given for the transmission of the rectangular-section mirror light pipe. The expression is used to model throughputs for simulated solar conditions over a calender year. It is found that the splaying of a mirror light pipe results in a significant increase in throughputs particularly in winter months.

No-loss bent light pipe with an equiangular spiral
Optics Letters, 2005Bending a light pipe and maintaining the required volume and size, while at the same time preserving source energy and minimizing bend losses, is the basic criterion for designing a light pipe. An important requirement is the design of a light pipe that is capable of being bent without loss of light and with no limitations on acceptance angle.

Shape deformation of a light flash through a light pipe
Nuclear Instruments and Methods, 1976Abstract The propagation of a LED light pulse entering a rectangular light pipe under different angles is studied by the single-photon counting technique. A comparison with the theoretical predictions based on geometrical optics is reported.

Aluminized Polystyrene Light Pipes
Review of Scientific Instruments, 1964Hollow tubes made of thin aluminized polystyrene sheets were used to pipe light from scintillation and Cherenkov radiators to photomultipliers. The light collection was found to be more than adequate in the geometries tested.
