Definition and physical nature of luminous flux<\/h2>\n

Lumen (symbol: lm) is the main unit of luminous flux. It is a physical quantity that indicates the amount of light emitted by a given light source and is visible to the human eye. Lumen measures the amount of light produced by a light source, regardless of the direction in which the light is emitted.<\/p>\n

Practical Use of Lumen<\/h3>\n

One lumen corresponds to a luminous flux of one candela (the unit of luminous intensity) uniformly distributed in all directions. A light source that emits more lumens is brighter than one with fewer lumens.<\/p>\n

Lumen is used as a unit to specify the brightness of various light sources (such as bulbs, LEDs, and discharge lamps). A light meter, or photometer, is used to measure lumens.<\/p>\n <\/div>\n <\/div>\n <\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":0,"template":"","class_list":["post-4063","glossary","type-glossary","status-publish","hentry"],"acf":[],"yoast_head":"\nLumen \u2013 veli\u010dina, sveteln\u00fd l\u00fa\u010d \u2013 slovn\u00edk pojmov | Hurricane.sk<\/title>\n<meta name=\"description\" content=\"Lumen je fyzik\u00e1lna veli\u010dina.
