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.

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 12mm wide, so it needs a channel with at least 14mm inner width (12mm + 2mm clearance). Every profile below meets that.

Perguntas Frequentes

Quais são as principais especificações do 4439?

4439: 2835, 84 LEDs/m, 24V, PCB de 12 mm, FPCB com cobre de 3oz, corte a cada 6LEDs/71.42mm. 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 trecho único desta Fita de LED para trechos ultralongos?

O comprimento máximo de um trecho único deste modelo é de 15M. Alimentar pelas duas extremidades ou usar uma derivação no ponto central reduz à metade a distância efetiva por segmento, portanto uma Fita de LED para trechos ultralongos pode cobrir 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, classificação de IRC (CRI), largura do PCB, impermeabilização e identificação com marca própria podem ser especificados. Solicite um Orçamento para consultar o prazo de entrega e os preços para o projeto.

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.

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

A tensão ainda cai ao longo do cobre, mas o IC de corrente constante de cada segmento mantém a corrente dos LEDs fixa até que a tensão local fique abaixo do seu limite mínimo de regulação. Assim, o brilho permanece uniforme de ponta a ponta, e a alimentação pode ser injetada em uma extremidade, nas duas extremidades ou em qualquer ponto intermediário do trecho.
