As the current decreases further, the color temperature changes to a warmer color. Of course these problems in general actual lighting may not be a big problem. However, in the RGB LED system, it will cause color deviation, and the human eye is very sensitive to color deviation, so it is not allowed. Modulating current can cause serious problems that make the constant current source not work, but in practice, modulating light by modulating forward current can cause a more serious problem. LED is usually driven by dC-DC constant current drive power supply, and this kind of constant current drive source is usually divided into boost type or buck type two (of course, there are lift pressure type, but because of low efficiency, expensive and not commonly used).\n\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3203agg.html\" style=\"color: #333;\">3203AGG</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3203AGG.pdf\" style=\"color: #333;\">3203AGG</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3203bgg.html\" style=\"color: #333;\">3203BGG</a> Display <a href=\"http://www.xlitx.com/datasheet/3203BGG.pdf\" style=\"color: #333;\">3203BGG</a> 0.30 inch\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3201aw.html\" style=\"color: #333;\">3201AW</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3201AW.pdf\" style=\"color: #333;\">3201AW</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3201bw.html\" style=\"color: #333;\">3201BW</a> Display <a href=\"http://www.xlitx.com/datasheet/3201BW.pdf\" style=\"color: #333;\">3201BW</a> 0.30 inch\n\n<hr style=\"border:1px solid;\">\n\n<a href=\"https://gingkoapp.com/the-light-source-with-ra-100-value.html\" style=\"color: #333;\">The light source with Ra 100 value</a>\n<a href=\"https://gingkoapp.com/the-standby-led-lighting-of-emergency.html\" style=\"color: #333;\">The standby LED lighting of emergency</a>\n<a href=\"https://gingkoapp.com/led-light-source-index-and-average-life.html\" style=\"color: #333;\">LED light source index and average life</a>\n<a href=\"https://gingkoapp.com/led-incandescent-lamp-color-response.html\" style=\"color: #333;\">LED incandescent lamp color response</a>\n<a href=\"https://gingkoapp.com/color-performance-of-led-light-source.html\" style=\"color: #333;\">Color performance of LED light source</a>\n<a href=\"https://gingkoapp.com/color-temperature-led-source-irradiation.html\" style=\"color: #333;\">Color temperature LED source irradiation</a>\n<a href=\"https://gingkoapp.com/change-the-brightness-of-the-led.html\" style=\"color: #333;\">Change the brightness of the LED</a>\n<a href=\"https://gingkoapp.com/led-chips-provide-control-voltage-interface.html\" style=\"color: #333;\">LED chips provide control voltage interface</a>\n<a href=\"https://gingkoapp.com/in-the-rgb-led-system.html\" style=\"color: #333;\">In the RGB LED system</a>\n<a href=\"https://gingkoapp.com/led-supply-voltage-and-load-voltage.html\" style=\"color: #333;\">LED supply voltage and load voltage</a>"}],"tree":{"_id":"26716f23c3ffb547c8000034","name":"In the RGB LED system","publicUrl":"in-the-rgb-led-system"}}
