Calculateur de Bande LED : Puissance, Chute de Tension & Lux | DENO
ProCalc™ est une suite gratuite de calculatrices de rubans LED de DENO LED Lighting, un fabricant OEM/ODM basé à Shenzhen et Foshan. Les modules couvrent le dimensionnement de l'alimentation (W/m × longueur × déclassement), la chute de tension sur les FPCB 12V/24V/48V avec 1oz, 2oz et 35+70µm de cuivre, les objectifs de lumens et de lux, la planification des unités de coupe et de la gradation, la sélection d'environnement IP20–IP68, la prédiction de profil sans points visibles et le rapport de spectre CRI/R9/TM-30. Les paramètres saisis une seule fois sont transmis à chaque module, peuvent être chargés à partir de modèles DENO réels, et peuvent être exportés sous forme de PDF d'ingénierie pour demander un devis de ruban LED OEM, ODM ou entièrement personnalisé.
What each LED strip calculator answers
ProCalc™ is a free LED strip calculator suite published by DENO LED Lighting, a Shenzhen and Foshan based manufacturer of flexible linear lighting. Every module runs on the same parameter set, so a value entered once flows through power sizing, run length, illuminance and compliance without re-entry.
LED strip power supply calculator: total load is power per metre multiplied by run length, then sized at roughly 120 per cent so the driver never sits at full output. A 14.4 W/m tape over 5 m draws 72 W and wants a 90 W driver; over 20 m it needs 288 W or a split feed.
LED strip voltage drop calculator for 12V, 24V and 48V runs: copper resistance, feed topology and system voltage decide how far a run can go before the far end visibly dims. The simulator models 1 oz, 2 oz and 35+70 micron copper with single-end, both-end and mid-point feeding, and reports worst-case end-of-run brightness.
Lumen and lux calculator: enter target illuminance, mounting height and profile transmittance and the suite returns the lm/m the tape must deliver, the wattage that implies and the efficacy needed to stay inside the energy class being specified.
- Cutting and dimming planner — cut units per length, offcut waste, and whether PWM, 0-10V, DALI or linear constant-current dimming suits the driver.
- IP rating and environment selector — IP20, IP65, IP67 and IP68 construction mapped to real installations.
- Dot-free profile advisor — LED pitch, profile depth, diffuser transmittance and beam angle combined to predict a continuous line of light.
- Spectrum reporter — CRI, R9, TM-30 fidelity and gamut for violet-excited full spectrum tape.
From calculation to a custom LED strip built to your numbers
The result of a calculation is a specification: a wattage per metre, a run length, a copper weight, an IP construction and a colour target. DENO builds to exactly that specification as a custom LED strip manufacturer — OEM production under your brand, ODM development from your performance brief, bespoke FPCB width and cut unit, private-label reels, printed labels and your own ordering codes.
Typical requests engineers bring here: a non-standard voltage for a long facade run, a tighter LED pitch for a shallow profile, a 2 oz or double-layer copper build for a corridor, a sealed IP68 variant for an in-ground detail, or a full spectrum tint for a gallery. Export the ProCalc report, attach it to an enquiry, and the engineering team quotes against the same numbers.
