32、ze thenomenclature in its field. The Societys Committee on Nomenclature and Standards published a provisional set of definitions in 1910. This subsequently was revised and enlarged ninetimes during the following 32 years. The reports of 1922, 1925, 1932, and 1942 were approved as American Standards

33、by the American Standards Association, and the IES was designat-ed as sponsor for future revisions under the procedure of the Association.The last American National Standard Nomenclature and Definitions for Illuminating Engineering (RP-16) was completed and approved by the Society and by the America

34、n National Standards Institute(ANSI) in 2005.Since the last revisions, advances in lighting technology have given birth to new lighting terminology.Better measurement techniques have led to more international agreement in fundamental units andconstants used in basic laws of physics. There is greater

35、 use of SI units today in illuminating engi-neering. This standard reflects the above with several new terms and definitions and revisions in exist-ing definitions submitted through the continuous maintenance process.The IES Nomenclature Committee, which has been primarily responsible for this revis

36、ion, acknowl-edges the material contributions of the technical committees of the Illuminating Engineering Society inproviding suggested terms and definitions pertinent to their specialized activities.IES Nomenclature CommitteeJames R.

Since, however, most light sources furnish radi-ant energy also in the adjoining infrared and ultravioletregions, and since many lamp-type d

39、evices are usedfor the production of radiant energy in these regions, itis customary to include the infrared and ultraviolet with-in the province of the illuminating engineer.1.2 Spectral ParametersThere are four spectral parameters that are widelyused in different disciplines. The spectral paramete

40、rused in illuminating engineering is almost alwayswavelength, , in units of nanometer (nm = 10-9m),micrometer (m = 10-6m) or ngstromi( = 10-10m).The name wavelength and symbol will be used asthe spectral parameter in this publication exceptwhere otherwise specifically indicated. The otherspectral pa

41、rameters, their symbols and equationsfor computing them from wavelengths in nanome-ters are as follows:Frequency,ii (Hz) = c 109/ (s-1) or (Hz)Wavenumber, (cm-1) = ()-1 107(cm-1)Photon energy, q (J) q = h 109/ (J)where:c = the speed of light in vacuum, 299,792,458 (m s-1)h = the Planck constant of a

42、ction 6.626176 10-34(J s)When a parameter symbol, e.g., , is used as asubscript to a radiometric quantity symbol, itdenotes the parameter concentration of that quanti-ty, e.g., spectral radiant flux, = d/d. To denotea distribution, it is also shown as a function of thatparameter, e.g., the spectral

43、distribution of radiantflux, (). Properties, such as reflectance or emis-sivity, also vary with, and may be shown as func-tions of, the radiation parameters, e.g., directionalemissivity (,), or spectral transmittance ().Since they are not distributions, but only weightingfunctions, the use of parame

44、ter subscripts to prop-erty symbols may be misleading and is accordinglydeprecated. The value of a function (distribution orweighting function) at a particular parameter valueis denoted by replacing the parameter symbol in thefunction notation by that value, e.g., spectral flux at555 nanometers woul

45、d be (555 nm).Note: In addition to the spectral parameter, the otherradiation parameters that together fully characterizethe distribution of radiant flux in the domain of rayoptics are: the spatial parameters of position (x,y for apoint on a surface or x,y,z for a point in space) anddirection (,)whe
