The lumen symbol lm is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Luminous flux differs from power radiant flux in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model a luminosity function of the human eyes sensitivity to various wavelengths. Lumens are related to lux in that one lux is one lumen per square meter. The lumen is defined in relation to the candela as. A full sphere has a solid angle of 4 steradians,1 so a light source that uniformly radiates one candela in all directions has a total luminous flux of 1 cd 4 sr 4 cdsr 1. ExplanationeditIf a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen 1 cd1 sr 1 lm. Alternatively, an isotropic one candela light source emits a total luminous flux of exactly 4 lumens. If the source were partly covered by an ideal absorbing hemisphere, that system would radiate half as much luminous fluxonly 2 lumens. The luminous intensity would still be one candela in those directions that are not obscured. The lumen can be thought of casually as a measure of the total amount of visible light in some defined beam or angle, or emitted from some source. The number of candelas or lumens from a source also depends on its spectrum, via the nominal response of the human eye as represented in the luminosity function. The difference between the units lumen and lux is that the lux takes into account the area over which the luminous flux is spread. A flux of 1. 00. 0 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1. The same 1. 00. 0 lumens, spread out over ten square metres, produces a dimmer illuminance of only 1. Mathematically, 1 lx 1 lmm. A source radiating a power of one watt of light in the color for which the eye is most efficient a wavelength of 5. So a lumen represents at least 16. LightingeditLamps used for lighting are commonly labelled with their light output in lumens in many jurisdictions this is required by law. A 2. 3 W spiral compact fluorescent lamp emits about 1,4. Many compact fluorescent lamps and other alternative light sources are labelled as being equivalent to an incandescent bulb with a specific wattage. Below is a table that shows typical luminous flux for common incandescent bulbs and their equivalents. Electrical power equivalents for differing lamps56Minimum light output lumensElectrical power consumption wattsIncandescent non halogenCompact fluorescent. LED2. 00. 25. 3 5. On September 1, 2. European Union legislation came into force mandating that lighting equipment must be labelled primarily in terms of luminous flux lm, instead of electric power W. This change is a result of the EUs Eco design Directive for Energy using Products Eu. P. 1. 2 For example, according to the European Union standard, an energy efficient bulb that claims to be the equivalent of a 6. W tungsten bulb must have a minimum light output of 7. Projector outputeditANSI lumenseditThe light output of projectors including video projectors is typically measured in lumens. A standardized procedure for testing projectors has been established by the American National Standards Institute, which involves averaging together several measurements taken at different positions. For marketing purposes, the luminous flux of projectors that have been tested according to this procedure may be quoted in ANSI lumens, to distinguish them from those tested by other methods. ANSI lumen measurements are in general more accurate than the other measurement techniques used in the projector industry. This allows projectors to be more easily compared on the basis of their brightness specifications. The method for measuring ANSI lumens is defined in the IT7. First the projector is set up to display an image in a room at a temperature of 2. Celsius. The brightness and contrast of the projector are adjusted so that on a full white field, it is possible to distinguish between a 5 screen area block of 9. The light output is then measured on a full white field at nine specific locations around the screen and averaged. This average is then multiplied by the screen area to give the brightness of the projector in ANSI lumens. Peak lumenseditPeak lumens is a measure of light output normally used with CRT video projectors. The testing uses a test pattern typically at either 1. The light output is measured just in this center area. Limitations with CRT video projectors result in them producing greater brightness when just a fraction of the image content is at peak brightness. For example, the Sony VPH G7. Q CRT video projector produces 1. ANSI lumens. 1. 7Color light outputeditBrightness white light output measures the total amount of light projected in lumens. The color brightness specification Color Light Output measures red, green, and blue each on a nine point grid, using the same approach as that used to measure brightness. Experts advise projector buyers to make certain that white light output and color light output are equal for optimum viewing experiences. SI photometry unitseditStandards organizations recommend that photometric quantities be denoted with a suffix v for visual to avoid confusion with radiometric or photon quantities. For example USA Standard Letter Symbols for Illuminating Engineering USAS Z7. Y1. 0. 1. 8 1. 96. Alternative symbols sometimes seen W for luminous energy, P or F for luminous flux, and or K for luminous efficacy. J here is the symbol for the dimension of luminous intensity, not the symbol for the unit joule. See alsoeditNotes and referenceseditLesson introduction to solid angles. Retrieved Oct 4, 2.
