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 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 3960?

3960: 2835, 130LEDs/m, DC 48V, PCB de 10mm, FPCB com cobre de 3oz, corte a cada 13LEDs/100mm. 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 para este modelo é de 15m. Alimentar 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 (CCT), classificação de IRC (CRI), largura da 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.

Qual comprimento uma Fita de LED de 48V pode atingir com um único ponto de alimentação?

Uma Fita de LED de 48V normalmente atinge o dobro do comprimento de uma Fita de LED equivalente de 24V com a mesma densidade de potência, sendo comuns trechos de 20 a 40 m alimentados por uma extremidade em baixas potências. O limite exato depende da potência em watts por metro e da gramatura do cobre; portanto, confirme-o com a calculadora de queda de tensão da DENO antes de especificar.

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 em watts por metro, cobre de 2 oz ou mais espesso e uma tensão de barramento mais alta, como 24V, 36V ou 48V, para atingir 20 m ou mais a partir de um único ponto de alimentação, mantendo a queda de tensão dentro de 3 por cento.
