LED luminous flux, in unit of Lumen (LM). All radiant energy emitted by a light source and perceived by human eyes is called luminous flux. Luminous intensity (luminous intensity,I). The flux of a light source at a solid Angle in a certain direction. Generally, LED light sources emit light flux in different directions at different intensives. The intensity of visible light emitted ina particular direction is called Illuminance (E, Lux, Lx). Illuminance is the ratio of the luminous flux to the surface being illuminated. Luminance (L) refers to the intensity of light reflected from an object seen by the eye in one direction. Luminance (L) refers to the efficiency with which electrical energy is converted into light energy. Luminance (L), unit, candela per square meter (CD/square meter).\n\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3101ab.html\" style=\"color: #333;\">3101AB</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3101AB.pdf\" style=\"color: #333;\">3101AB</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3101bb.html\" style=\"color: #333;\">3101BB</a> Display <a href=\"http://www.xlitx.com/datasheet/3101BB.pdf\" style=\"color: #333;\">3101BB</a> 0.30 inch\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3011ab.html\" style=\"color: #333;\">3011AB</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3011AB.pdf\" style=\"color: #333;\">3011AB</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3011bb.html\" style=\"color: #333;\">3011BB</a> Display <a href=\"http://www.xlitx.com/datasheet/3011BB.pdf\" style=\"color: #333;\">3011BB</a> 0.30 inch\n\n<hr style=\"border:1px solid;\">\n\n<a href=\"https://gingkoapp.com/the-unit-price-of-1w-white-led.html\" style=\"color: #333;\">The unit price of 1W white LED</a>\n<a href=\"https://gingkoapp.com/home-applications-of-led-lighting.html\" style=\"color: #333;\">Home applications of LED lighting</a>\n<a href=\"https://gingkoapp.com/12v-and-24v-led-lamp-application.html\" style=\"color: #333;\">12V and 24V LED lamp application</a>\n<a href=\"https://gingkoapp.com/led-lighting-power-supply-system-is-complex.html\" style=\"color: #333;\">LED lighting power supply system is complex</a>\n<a href=\"https://gingkoapp.com/chinese-lighting-market-is-huge.html\" style=\"color: #333;\">Chinese lighting market is huge</a>\n<a href=\"https://gingkoapp.com/color-and-brightness-of-led-in-different-occasions.html\" style=\"color: #333;\">Color and brightness of LED in different occasions</a>\n<a href=\"https://gingkoapp.com/leds-luminous-intensity-unit-is-candela.html\" style=\"color: #333;\">Leds Luminous Intensity Unit is Candela</a>\n<a href=\"https://gingkoapp.com/led-luminous-flux-in-unit-of-lumen.html\" style=\"color: #333;\">LED luminous flux in unit of Lumen</a>\n<a href=\"https://gingkoapp.com/led-luminance-refers-to-the-light-intensity-density.html\" style=\"color: #333;\">LED Luminance refers to the light intensity density</a>\n<a href=\"https://gingkoapp.com/the-color-rendering-of-led-may-be-different.html\" style=\"color: #333;\">The color rendering of LED may be different</a>"}],"tree":{"_id":"2671d230330c0554e4000046","name":"LED luminous flux in unit of Lumen","publicUrl":"led-luminous-flux-in-unit-of-lumen"}}
