What is a constant current LED strip?

A constant current LED strip carries a linear CC driver IC on the board that holds a fixed current through each segment regardless of the input voltage seen at that point. Brightness therefore stays flat along the run, instead of falling off with voltage drop the way a plain constant-voltage strip does.

Constant current vs constant voltage LED strip — which is better?

Constant voltage is cheaper and fine for short runs under 3 m. Constant current is the right choice whenever the run is long, the copper is thin, the input voltage is unstable, or the installation is camera-facing — the IC absorbs supply variation and keeps every metre at the same luminous flux.

Can a constant current LED strip be powered from both ends or mid-feed?

Yes. Because regulation happens per segment, DENO's CC boards accept single-end, both-ends and any mid-strip tap. Both-ends and mid-feed wiring halve the effective feed distance, which is how a single driver covers a long corridor or perimeter cove.

Does a constant current LED strip dim without flicker?

It does when the driver is matched to it. Linear CC ICs dim smoothly on PWM down to about 1%, and at 16 kHz+ PWM the run is flicker-free on camera (low Pst LM and SVM). Analogue dimming of a CC board is not recommended below 20% because the IC needs headroom.

How long can a constant current LED strip run be?

Up to 20 m and beyond on 24V or 48V builds with 2 oz copper, versus 5 m for a comparable constant-voltage board. The practical limit becomes the copper's current-carrying capacity and thermal design rather than perceived brightness fall-off.

Can I order a custom constant current LED strip?

Yes — segment length, drive current, voltage, LED density, CCT/CRI, PCB width and copper weight are all configurable, and CC regulation can be combined with high-density, ultra-narrow or full-spectrum layouts on the same board.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide

At up to 24W/m, 3348 is a high-power SMD LED strip. Above roughly 14.4W/m the tape can no longer shed its own heat through the FPC alone — an aluminum channel is part of the luminaire, not an accessory.

Why high-wattage strips need a heat sink

Aluminum conducts heat roughly 30× faster than the plastics, MDF or gypsum a strip is usually stuck to, so a bare high-power run traps heat under the tape.
LED lifetime (LM-80 / TM-21) is driven by solder-point temperature Tc. Keeping Tc inside the datasheet limit — DENO strips are rated Tc ≤ 75°C — is what preserves the rated L70 lifetime and colour stability.
Never run 14.4W/m or more coiled on the reel, inside a sealed plastic diffuser, or directly on wood, wallpaper or foam.

Sizing rule: FPC width vs channel inner width

Channel inner width ≥ FPC width + 2mm. This strip is 10mm wide, so it needs at least 12mm of inner width.
The 2mm clearance absorbs extrusion tolerance and lets the tape be seated or replaced without scraping the side walls or the wiring.
A frosted or opal PC cover then diffuses the higher lumen output into an even, dot-free line instead of visible hot spots.

Aluminum channels that fit this strip

Recommended LED Channels

Mount this LED strip in a DENO LED aluminum profile for heat dissipation, physical protection and diffused, dot-free output.

This strip is 10mm wide, so it needs a channel with at least 12mm inner width (10mm + 2mm clearance). Every profile below meets that.

Perguntas Frequentes

Quais são as principais especificações do 3348?

3348: 2835, 120 LEDs/m, 24V, PCB de 10mm, FPCB de cobre de 3 oz, corte a cada 6LEDs/50mm. Dados fotométricos completos, diagramas de ligação e relatórios de ensaio estão disponíveis na seção de downloads desta página.

Qual pode ser o comprimento de um único trecho desta Fita de LED para trechos ultralongos?

O comprimento máximo de um único trecho deste modelo é de 10m. A alimentação pelas duas extremidades ou por um ponto central reduz pela metade a distância efetiva por segmento, permitindo que uma Fita de LED para trechos ultralongos cubra o dobro desse comprimento em um único circuito quando conectada dessa forma.

A DENO pode personalizar esta Fita de LED para trechos ultralongos para um projeto?

Sim. A DENO fabrica a série de Fitas SMD Ultralongas como fornecedora OEM e ODM: comprimento do rolo, temperatura de cor, classe de IRC (CRI), largura da PCB, impermeabilização e identificação com marca própria podem ser especificados. Solicite um Orçamento para obter o prazo de entrega e os preços para o projeto.

Uma Fita de LED de corrente constante realmente elimina a queda de tensão?

A tensão ainda cai ao longo do cobre, mas o circuito integrado de corrente constante de cada segmento mantém a corrente dos LEDs fixa até que a tensão local caia abaixo do seu limiar de dropout. Assim, o brilho permanece uniforme de ponta a ponta, e a alimentação pode ser aplicada em uma extremidade, nas duas extremidades ou em qualquer ponto intermediário do trecho.

O que limita o comprimento de um trecho de Fita de LED?

A queda de tensão e a corrente no condutor, não o LED em si. Uma Fita de LED para trechos longos combina baixa potência por metro, cobre de 2 oz ou mais espesso e uma tensão de barramento mais alta, como 24V, 36V ou 48V, para alcançar 20 m ou mais a partir de um único ponto de alimentação, mantendo a queda de tensão dentro de 3 por cento.
