Light distributions in rooms

Journal of the Franklin Institute, 1946
Abstract A few unofficial terms used in the paper are as follows: pharos F = luminous flux (lumen), pharosage D = luminous flux density (lumen m−2), helios H = generalized brightness: H=π lim ω→0 D ω If D is in lumens per square meter and ω is in steradians, then H is expressed in blondels.

P‐12.1: Lighting effects, light distribution matters

SID Symposium Digest of Technical Papers, 2019
The interaction between light and its surroundings (i.e. the geometry and materials) shapes the lighting distribution and determines the appearance of scenes and its visual experiences. In this study, we introduced the concept of light distribution solids by distinguishing luminance distribution solids and illuminance distribution solids. It is helpful

Distributed Lighting Systems: Uniform Light Delivery

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">High efficiency distributed lighting systems for automotive vehicles are now possible with the development of high brightness Xenon Metal Halide light sources and the advent of new low loss, low cost light pipes. In principle, all of the lighting functions in a vehicle can now be accomplished with one or two such ...

Cherenkov light distribution function

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1987
Abstract We have obtained a a light distribution function which is an intensity distribution function of Cherenkov radiation projected onto a plane. Using the function we made a reconstruction program to know the incident position, polar (θ) and azimuthal (φ) angles of a charged particle in water by detecting its Cherenkov light.

Light Distribution Photometry in Japan

Applied Optics, 1971
Of the representative distribution photometers constructed in Japan, a large-size photometer without mirrors, a compensation method for the variation in light output of a lamp, and an automatic recording of a sinusoidal isocandela diagram are illustrated.

Automotive Distributed Lighting: Regionally

SAE Technical Paper Series, 2000
<div class="section abstract"><div class="htmlview paragraph">Very small PC lamps are used with localized waveguides to construct regional distributed lighting systems (DLS). This approach reduces the size, cost, and redesign of implementing DLS illumination. Wattage usage is decreased, and installation complexity is reduced.

Light Distribution

2016
This chapter describes (1) how light distributes within a leaf canopy and (2) light interception by leaves. Basic equations are shown so that readers can make light distribution models by themselves.

Light scattering measurements of particle distributions

Applied Optics, 1976
Specially designed Fraunhofer plane masks are described for passing diffracted flux in proportion to the second, third, and fourth power of the radius of spherical particles. For a distribution of particles, the total volume of the particles can be monitored using the third power mask to produce a signal proportional to the sum of the cubes of the ...

AFS Light Distribution Control

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">The light distribution concepts of bending light as Adaptive Front Lighting System (AFS) were investigated when running on a curved road. In order to improve visibility on a curved road, we studied not only how to swivel the distribution pattern but also what would prevent us from safe driving when the lights were ...
