The luminous efficacy of a source is a measure of the efficiency with which the source provides visible light from electricity.[4] The luminous efficacy of radiation describes how well a given quantity of electromagnetic radiation from a source produces visible light: the ratio of luminous flux to radiant flux.[5] Not all wavelengths of light are equally visible, or equally effective at stimulating human vision, due to the spectral sensitivity of the human eye; radiation in the infrared and ultraviolet parts of the spectrum is useless for illumination. The overall luminous efficacy of a source is the product of how well it converts energy to electromagnetic radiation, and how well the emitted radiation is detected by the human eye. Efficacy and efficiency[edit] In some systems of units, luminous flux has the same units as radiant flux.
The luminous efficacy of radiation is then dimensionless. Luminous efficacy of radiation[edit] Explanation[edit] Mathematical definition[edit] where Note that. Lighting Installation - Fiswiki. From Fiswiki Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm). In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.
Floodlights are broad-beamed, high-intensity artificial lights often used to illuminate outdoor playing fields while an outdoor sports event is being held during low-light conditions. [edit] Lighting Installations for Freestyle Skiing The International Competition Rules (ICR) have the following reference regarding lighting for ski competitions; 4800.1.1 The light level anywhere on the course may not be less than 80 lux, measured parallel to the surface.
[edit] Fundamentals of Good Illumination The goal of good sports lighting is to provide a luminous environment that contributes to the contrast of the object, the competitors, and the surrounding backgrounds. [edit] Outdoor sports lighting Deer Valley, USA. Energy Saving Lamps - Photometry Applet.
