The light intensity of a single indoor LED is generally 500UCD-50mcD, while that of a single outdoor LED is generally 100McD-1000McD, or even more than 1000McD. Wavelength, the distance between two consecutive points of the same phase at the same time in the direction of periodic wave propagation. LED light and radiation, light is electromagnetic radiation (energy travels from one object to another without any medium in the process. This mode of energy transmission is called radiation) reaches the eye and is converted by the optic nerve into light, the part of the spectrum that can be seen by the naked eye.\n\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3101as.html\" style=\"color: #333;\">3101AS</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3101AS.pdf\" style=\"color: #333;\">3101AS</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3101bs.html\" style=\"color: #333;\">3101BS</a> Display <a href=\"http://www.xlitx.com/datasheet/3101BS.pdf\" style=\"color: #333;\">3101BS</a> 0.30 inch\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3011as.html\" style=\"color: #333;\">3011AS</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3011AS.pdf\" style=\"color: #333;\">3011AS</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3011bs.html\" style=\"color: #333;\">3011BS</a> Display <a href=\"http://www.xlitx.com/datasheet/3011BS.pdf\" style=\"color: #333;\">3011BS</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":"2671d8a2330c0554e4000042","name":"Leds Luminous Intensity Unit is Candela","publicUrl":"leds-luminous-intensity-unit-is-candela"}}
