Hva er minimum søylediameter for fleksible LED-moduler?

764 mm for 240 × 120 mm moduler og 815 mm for 320 × 160 mm moduler. Dette er harde mekaniske grenser bestemt av det fleksible PCB-substratet og silikonchassiset, ikke av pikselavstand. En søyle under 764 mm kan ikke pakkes inn med standard DOIT VISION fleksible moduler.

Hvor mange fleksible LED-moduler får plass rundt en søyle?

Modulantall per ring = (søyleomkrets × 0.78) ÷ modulbredde, avrundet. For en søyle med 1000 mm diameter og moduler med 240 mm bredde: omkretsen er 3,142 mm, × 0.78 = 2,451 mm, ÷ 240 = 10.2 → 10 moduler per ring. Skriv inn diameteren din i kalkulatoren ovenfor for å få det nøyaktige antallet.

Hvorfor dekker ikke diagrammet 100 % av kolonneomkretsen?

En list dekker de resterende 15–20 % bak på søylen, der den vender mot veggen. Påføringsfaktoren på 78 % er bransjestandarden. Å forsøke 100 % dekning med moduler med fast bredde vil kreve tilpasset kanttrimming, noe som introduserer risiko for skade.

Kan jeg pakke inn en firkantet eller rektangulær søyle med fleksible LED-moduler?

Fleksible moduler følger kurver, ikke skarpe 90°-hjørner. Bygg en buet metallramme rundt søylen som glatter ut hjørnene til en avrundet profil. DOIT VISION tilbyr CAD-tegninger for konverteringer fra firkant til rund.

Hva om søylen min er nøyaktig på minimumsgrensen – 764 mm?

Gjennomførbart med moduler på 240 × 120 mm, men bøyespenningen er på nominell maksimum. Bruk GOB-moduler for å redusere risikoen for håndteringsskader, og lag stålrammen med en litt større ytre diameter (770–774 mm) hvis den arkitektoniske søylen tillater det.

Påvirker pikselavstanden beregningen av kolonnebryting?

Nei. Pikselavstand påvirker oppløsning og kostnad, men den mekaniske bøyningsgrensen settes av de fysiske modulens dimensjoner. En P1.25- og P4-modul i samme formfaktor på 240 × 120 mm deler samme minimumsdiameter på 764 mm. Velg pikselavstand basert på synsavstand.

Hva skjer hvis jeg bestiller moduler og kolonnen ikke passer?

Før en bestilling sendes, gjennomgår en tekniker bildet av søylen, diameteren og omviklingshøyden. Hvis standardmodulene ikke passer, foreslår vi alternativer – tilpasset rammegeometri, hybridløsninger eller tilpassede modulstørrelser. Denne gjennomgangen er gratis og skjer innen 24 timer.

Tre tall du trenger

Kolonnediameter. Measure it. Wrap a flexible tape measure around the column, get the circumference, and divide by 3.1416 (π). No flexible tape measure? Use string and measure the string. An estimate off by 20mm can mean the difference between feasible and not feasible at the 764mm threshold.

Viklingshøyde. How tall should the LED section be? Measure the vertical distance you want to cover. The calculator divides this by the module height (120mm or 160mm) to determine the number of vertical rows.

Modulstørrelse. 240×120mm wraps tighter columns (down to 764mm). 320×160mm gives fewer, larger modules per ring — faster installation, but a higher minimum diameter of 815mm.

02 — Hurtigreferanse

Minimum sylinderdiameter

Module Size	Min. sylinderdiameter	Min radius	Typiske moduler/ring
240 x 120mm	764mm	382mm	8–14 avhengig av diameter
320 x 160mm	815mm	408mm	6–10 avhengig av diameter

Viktig: These limits are determined by module dimensions, not pixel pitch. A P1.25 module and a P4 module in the same 240×120mm form factor share the same 764mm minimum diameter — the PCB substrate is the same size regardless of how tightly the LEDs are spaced. Choose pixel pitch based on viewing distance, not mechanical constraints.

03 — Forstå resultatet

Hva hvert tall betyr

Moduler per ring. Calculated as (column circumference × 0.78) ÷ module width, rounded to the nearest whole number. The 78% factor accounts for the trim strip — roughly 22% of the circumference is covered by a filler panel at the column rear, facing a wall where it’s never seen. No one covers 100% of a cylinder circumference with LEDs.

Totalt antall moduler. Modules per ring × vertical rows (wrap height ÷ module height, rounded up). Each row adds exactly one module height.

Visningsområde. Module width × height × total modules ÷ 1,000,000. This is LED surface only — not the full column surface area.

Modulestimat (USD). Rough module hardware cost at $800–$1,500/m² (modules only — no frame, controller, shipping, or installation). Actual price depends on pixel pitch, GOB option, quantity, and destination. Send the column details for a line-item quotation.

78 % faktornyanse: In practice the application factor ranges from 75% to 80% depending on column accessibility and the trim solution. The calculator uses 78% as a midpoint. Actual module count may vary by ±1 module per ring — confirm the final count with the engineer reviewing your floor plan.

764mm for 240×120mm modules and 815mm for 320×160mm modules. These are hard mechanical limits determined by the flexible PCB substrate and silicone chassis dimensions — not by pixel pitch. A column under 764mm cannot be wrapped with standard DOIT VISION flexible modules. Contact Kris for custom module options for smaller diameters.

Module count per ring = (column circumference × 0.78) ÷ module width, rounded. For a 1000mm diameter column with 240mm-wide modules: circumference is 3,142mm, × 0.78 = 2,451mm, ÷ 240 = 10.2 → 10 modules per ring. Enter your diameter in the calculator above for the exact count.

A trim strip covers the remaining 15–20% where module edges meet at the rear of the column — positioned facing a wall and never visible. The 78% application factor is the industry standard. Attempting 100% coverage with fixed-width modules would require custom edge trimming, introducing damage risk and voiding warranty.

Flexible modules conform to curves, not sharp 90° corners. For a square pillar, build a curved metal frame around it that smooths the corners into a rounded profile. DOIT VISION provides CAD drawings for square-to-round conversions. Alternatively, use four rigid LED panels meeting at the corners.

It’s feasible with 240×120mm modules, but the bend stress is at the rated maximum. Recommendations: (1) use GOB modules to reduce handling damage risk during installation; (2) fabricate the steel frame to a slightly larger outer diameter (770–774mm) if the architectural column allows — a 6–10mm increase makes no visual difference but significantly reduces long-term PCB stress.

No — a common misconception. Pixel pitch (P1.2 through P4) affects resolution and cost, but the mechanical bend limit is set by the physical module dimensions. A P1.25 module and a P4 module in the same 240×120mm form factor share the same 764mm minimum diameter. Choose pixel pitch based on viewing distance requirements, not mechanical constraints.

Before any order ships, our engineer reviews your column photo, diameter measurement, and intended wrap height. If standard modules don’t fit, we propose alternatives: custom frame geometry to increase the effective diameter, a hybrid rigid-flexible solution, or custom module sizes. This review is free and happens within 24 hours of your enquiry — before any purchase commitment.
