However, many users may encounter a common problem during installation\u2014the LED light strip doesn&#8217;t working after cutting. So what exactly causes this phenomenon? In this article, we will analyze the reasons for this problem in detail and provide relevant solutions to help you easily solve this issue. More details, pls read <a href=\"https:\/\/neonledstrip.com\/nl\/hoe-werken-ledstriplampen\/\" target=\"_blank\" rel=\"noreferrer noopener\">Hoe werken LED Strip Lights?<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-can-led-strip-lights-only-be-cut-at-specific-locations\">Waarom kunnen LED Strip Lights alleen op specifieke locaties worden geknipt?<\/h2>\n\n\n\n<p>LED strips cannot be arbitrarily cut; the circuit board for each LED is pre-designed. If you look closely at the light strip, you&#8217;ll see a pair of copper contact points marked with a scissor icon at short intervals. These are the designated cutting points; you can only cut at these locations.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"500\" src=\"https:\/\/neonledstrip.com\/wp-content\/uploads\/2026\/04\/led-strip-not-working-after-cutting.webp\" alt=\"LED-strip werkt niet na doorknippen met verbroken verbinding en onverlicht gedeelte\" class=\"wp-image-3376\" srcset=\"https:\/\/neonledstrip.com\/wp-content\/uploads\/2026\/04\/led-strip-not-working-after-cutting.webp 800w, https:\/\/neonledstrip.com\/wp-content\/uploads\/2026\/04\/led-strip-not-working-after-cutting-300x188.webp 300w, https:\/\/neonledstrip.com\/wp-content\/uploads\/2026\/04\/led-strip-not-working-after-cutting-768x480.webp 768w, https:\/\/neonledstrip.com\/wp-content\/uploads\/2026\/04\/led-strip-not-working-after-cutting-18x12.webp 18w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Het onderliggende principe is parallelschakeling. Een LED lichtstrip bestaat uit meerdere onafhankelijke lichtgevende eenheden die in serie en parallel zijn geschakeld. Elk snijpunt vertegenwoordigt het einde van een volledige circuiteenheid en het begin van de volgende. Binnen elke eenheid zijn de LED's en weerstanden in serie geschakeld, terwijl de eenheden zelf parallel zijn geschakeld.<\/p>\n\n\n\n<p>Als je op het juiste punt knipt, scheid je alleen een complete parallelle eenheid van het totale circuit zonder het stroompad binnen die eenheid te be\u00efnvloeden. Daarom kunnen het overblijvende deel en het afgesneden deel onafhankelijk functioneren.<\/p>\n\n\n\n<p>Omgekeerd, als je op de verkeerde plaats knipt, verstoor je het circuit in dat apparaat, waardoor dat apparaat en alle volgende apparaten niet meer branden.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-common-reasons-why-led-strip-don-t-working-after-cutting\">Common Reasons Why LED Strip Don&#8217;t Working After Cutting<\/h2>\n\n\n\n<p>Standaard LED-strips zijn 5 meter per rol, dus tijdens de installatie moet er worden geknipt. Natuurlijk zijn sommige op maat gemaakt. Let bij het knippen goed op de kniplocatie. Hier zijn vijf grote boosdoeners die ervoor zorgen dat de LED-strip niet werkt na het snijden.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-incorrect-cutting-position\">Verkeerde snijpositie<\/h3>\n\n\n\n<p>This is the most common reason why LED strips won&#8217;t light up after being cut. As mentioned earlier, the cut must be made precisely in the middle of the copper pads marked with scissors.<\/p>\n\n\n\n<p>If you cut anywhere else between the two pads, it&#8217;s equivalent to severing the delicate FPC (Flexible Printed Circuit) wiring inside the strip. Current cannot flow, and naturally, it won&#8217;t light up.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-reversed-positive-and-negative-terminals\">Omgekeerde positieve en negatieve aansluitingen<\/h3>\n\n\n\n<p>LED staat voor Light Emitting Diode (lichtdiode) en de belangrijkste eigenschap is geleiding in \u00e9\u00e9n richting. Er kan alleen stroom naar binnen stromen vanaf de positieve (+) aansluiting en naar buiten vanaf de negatieve (-) aansluiting.<\/p>\n\n\n\n<p>Wanneer <a href=\"https:\/\/neonledstrip.com\/nl\/how-to-cut-and-solder-led-neon-flex\/\" type=\"post\" id=\"2183\" target=\"_blank\" rel=\"noreferrer noopener\">een LED-strip snijden<\/a>, dan moet hij opnieuw verlicht worden. Als je de positieve en negatieve klemmen omdraait bij het opnieuw aansluiten van de doorgeknipte strip, zal de strip absoluut niet oplichten.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-damaged-or-cold-solder-joints\">Beschadigde of koude soldeerverbindingen<\/h3>\n\n\n\n<p>Als je ervoor kiest om de LED-strip aan te sluiten met solderen, is een zekere soldeervaardigheid vereist. Koude soldeerverbindingen (soldeer dat geen goed contact maakt met de pads en draden) of kortsluiting (te veel soldeer waardoor de positieve en negatieve aansluitingen met elkaar in contact komen) zorgen er allebei voor dat de LED-strip niet gaat branden.<\/p>\n\n\n\n<p>Bovendien kan het gebruik van een oververhitte soldeerbout of het te lang vasthouden van de soldeerbout de kwetsbare koperen pads beschadigen, waardoor ze loskomen van het flexibele substraat.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-led-strip-voltage-mismatch\">Verkeerde spanning LED Strip<\/h3>\n\n\n\n<p>LED strips werken op verschillende spanningen, meestal 12V en 24V. Deze mogen nooit gemengd worden. Als je een 12V strip aansluit op een 24V voeding, zullen de LED's onmiddellijk doorbranden door een te hoge spanning.<\/p>\n\n\n\n<p>Omgekeerd zal het aansluiten van een 24V-strip op een 12V-voeding ervoor zorgen dat de strip niet start of een extreem lage helderheid heeft.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-led-strip-damage-or-circuit-board-breakage\">Schade aan LED-strip of printplaatbreuk<\/h3>\n\n\n\n<p>Sometimes the problem isn&#8217;t with your handling. The LED strip itself may have suffered physical damage during shipping or installation, such as tiny cracks in the FPC circuit board that are difficult to see with the naked eye.<\/p>\n\n\n\n<p>It&#8217;s also possible that excessive force was used during installation or cutting. This can damage adjacent solder pads and cause the LED strip to fail to light up.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-properly-cut-led-strips\">Hoe snijd je LED Strips op de juiste manier?<\/h2>\n\n\n\n<p>Het beheersen van de juiste snijmethode is essentieel voor een goede werking van LED strips. Het snijden van LED strips is over het algemeen noodzakelijk.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Hoe te knippen, solderen en aansluiten van COB LED Strip\" width=\"720\" height=\"405\" src=\"https:\/\/www.youtube.com\/embed\/y2lZQs4lfg8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-1-power-off-operation\">Stap 1: Uitschakelen<\/h3>\n\n\n\n<p>Voordat u de LED-strip doorknipt, moet u altijd de voeding uitschakelen. Zorg ervoor dat de strip volledig spanningsloos is. Knippen terwijl het circuit onder spanning staat is niet alleen gevaarlijk, maar kan ook de strip beschadigen door kortsluiting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-2-precise-positioning\">Stap 2: Precieze positionering<\/h3>\n\n\n\n<p>Lay the LED strip flat on the work surface and carefully locate the cutting marks using sufficient light. These marks are usually indicated by a scissor icon, dotted lines, or the word &#8220;CUT HERE,&#8221; and are fixed in the center between the two copper foil pads.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-3-tool-selection\">Stap 3: Gereedschap selecteren<\/h3>\n\n\n\n<p>We moeten een scherpe schaar of een hobbymes gebruiken om te knippen. Bot gereedschap zal de printplaat samendrukken en mogelijk vervorming of zelfs breuk van de interne koperfolie veroorzaken. Professionele gebruikers wordt aangeraden een schaar te gebruiken die specifiek is voor elektronische onderdelen, voor een schonere snede.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-4-vertical-cutting\">Stap 4: Verticaal snijden<\/h3>\n\n\n\n<p>Houd het mes loodrecht op het oppervlak van de lichtstrip en maak een enkele, snelle snede; vermijd herhaaldelijk of schuin snijden. De snijrand moet netjes en glad zijn, vrij van bramen of gescheurd plastic afval.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-5-inspect-the-cut\">Stap 5: Inspecteer de snede<\/h3>\n\n\n\n<p>Inspecteer onmiddellijk na het knippen beide uiteinden van de snede om er zeker van te zijn dat de koperfolie-pads volledig blootliggen. Het oppervlak van de pads moet glad en vlak zijn, zonder bedekkende plastic resten; dit is cruciaal voor latere aansluitingen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-6-protective-treatment\">Stap 6: Beschermende behandeling<\/h3>\n\n\n\n<p>Als het afgeknipte uiteinde van de LED-strip niet onmiddellijk wordt gebruikt, is het aan te raden om de soldeerpads te omwikkelen met elektrische tape om het binnendringen van stof en vocht te voorkomen of om onbedoelde kortsluiting te vermijden.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-summary\">Samenvatting<\/h2>\n\n\n\n<p>Het op de juiste manier snijden van LED lichtstrips is essentieel om ervoor te zorgen dat ze daarna goed werken.

Op voorwaarde dat je op de juiste plaats knipt en een compatibele stroombron kunt leveren (solderen of een miniatuurconnector gebruiken), kan elk segment van de lichtstrip dat langer is dan een enkele snij-unit onafhankelijk functioneren.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1762571455742\"><strong class=\"schema-faq-question\">Kunnen LED lichtstrips overal worden gesneden?<\/strong> <p class=\"schema-faq-answer\">Nee, LED lichtstrips kunnen alleen op specifieke plaatsen worden gesneden. U moet de aangegeven snijlijnen op de strip volgen. Verkeerd knippen kan ervoor zorgen dat de lichtstrip niet correct functioneert of kan het circuit beschadigen. Elke lichtstrip heeft vooraf ontworpen snijpunten.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1762571456283\"><strong class=\"schema-faq-question\">Why won&#8217;t an LED strip light up after being cut?<\/strong> <p class=\"schema-faq-answer\">Er zijn verschillende mogelijke redenen. De redenen waarom een LED-strip niet oplicht na het knippen zijn onder andere: knippen op de verkeerde plaats, ompoling van de positieve en negatieve polariteit, beschadigde soldeerverbindingen, een spanningsverschil tussen de strip en de voeding of schade aan de printplaat.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1762571457534\"><strong class=\"schema-faq-question\">Heeft het snijden van een LED-strip invloed op de helderheid of kleurprestaties?<\/strong> <p class=\"schema-faq-answer\">Als de snede op de juiste plaats wordt gemaakt en het circuit onbeschadigd blijft, zullen de helderheid en kleurprestaties van de LED-strip niet worden be\u00efnvloed. Over het algemeen zal het snijden van de strip het lichteffect of de kleurweergave niet veranderen.<\/p> <\/div> <\/div>","protected":false},"excerpt":{"rendered":"<p>LED light strips are energy-efficient, can be cut, and are easy to install, while also supporting custom sizes.
