Open tube filament. If LED lamp tube is not seriously blackened, it can be used in emergency after connecting 0.047μF/400V polyester capacitor at both ends of the broken wire lamp pin. R1 and R2 are open or variable (generally, R1 is more likely to fail) and replaced with 1/4W high quality resistance of the same resistance value. The LED lights flickered. If the LED lamp tube is not seriously black, check whether D5 and D6 have false welding or open circuit, if D5 and D6 soft breakdown or filter capacitor C1 leakage and bad, will also make the light flicker. \n\n<a href=\"http://www.xlitx.com/datasheet/5161AGG.pdf\" style=\"color: #333;\">5161AGG</a> LED <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/5161agg.html\" style=\"color: #333;\">5161AGG</a> 7-segment <a href=\"http://www.xlitx.com/datasheet/5161BGG.pdf\" style=\"color: #333;\">5161BGG</a> display <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/5161bgg.html\" style=\"color: #333;\">5161BGG</a>\n\nLED luminescence mechanism. The LED consists of P region, N region, and the barrier region between them. The P region has extra holes, which can be regarded as a positively charged unit particle. There are extra electrons in the n-block, which are negative; The barrier is where the holes in the P region meet the electrons in the N region, and some equilibrium can be achieved without electricity. When a forward current is injected at both ends of the PN junction (i.e., the input of the DC regulated power supply), the injected non-equilibrium carriers (electron-hole pairs) compound luminescence during diffusion.\n\nCommon-Cathode CC <a href=\"http://www.xlitx.com/datasheet/8011AGG.pdf\" style=\"color: #333;\">8011AGG</a> 7-Segment digit <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/8011agg.html\" style=\"color: #333;\">8011AGG</a> LED Common-Anode CA <a href=\"http://www.xlitx.com/datasheet/8011BGG.pdf\" style=\"color: #333;\">8011BGG</a> Display <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/8011bgg.html\" style=\"color: #333;\">8011BGG</a> 0.80 inch\nCommon-Cathode CC <a href=\"http://www.xlitx.com/datasheet/CL8011AGG.pdf\" style=\"color: #333;\">CL8011AGG</a> 7-Segment digit <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/cl8011agg.html\" style=\"color: #333;\">CL8011AGG</a> LED Common-Anode CA <a href=\"http://www.xlitx.com/datasheet/CL8011BGG.pdf\" style=\"color: #333;\">CL8011BGG</a> Display <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/cl8011bgg.html\" style=\"color: #333;\">CL8011BGG</a> 0.80 inch\n\n<hr style=\"border:1px solid;\">\n\n<a href=\"https://gingkoapp.com/the-advantages-of-led-energy-saving-lamps.html\" style=\"color: #333;\">The advantages of LED energy-saving lamps</a>\n<a href=\"https://gingkoapp.com/power-supply-12v-led-misused-into-24v.html\" style=\"color: #333;\">Power supply 12V LED misused into 24V</a>\n<a href=\"https://gingkoapp.com/led-detection-process.html\" style=\"color: #333;\">LED detection process</a>\n<a href=\"https://gingkoapp.com/the-led-lights-flickered.html\" style=\"color: #333;\">The LED lights flickered.</a>\n<a href=\"https://gingkoapp.com/when-the-led-lamp-is-difficult-to-light.html\" style=\"color: #333;\">When the LED lamp is difficult to light</a>\n<a href=\"https://gingkoapp.com/led-lamps-and-ordinary-energy-saving-lamps.html\" style=\"color: #333;\">LED lamps and ordinary energy-saving lamps</a>\n<a href=\"https://gingkoapp.com/promoting-the-use-of-led-bulbs.html\" style=\"color: #333;\">Promoting the use of LED bulbs</a>\n<a href=\"https://gingkoapp.com/generation-of-green-light-source-led.html\" style=\"color: #333;\">Generation of green light source LED</a>\n<a href=\"https://gingkoapp.com/led-light-source-called-longevity-lamp.html\" style=\"color: #333;\">LED light source called longevity lamp</a>\n<a href=\"https://gingkoapp.com/led-light-source-is-low-pressure-microelectronics-product.html\" style=\"color: #333;\">LED light source is low pressure microelectronics product</a>"}],"tree":{"_id":"333b670ce82f1c9ce1000019","name":"The LED lights flickered.","publicUrl":"the-led-lights-flickered"}}
