Addressable SPI COB LED Strip — Pixel, No Hotspots

The SPI addressable COB LED strip integrates individually controllable ICs with Chip-on-Board (COB) technology, enabling dynamic lighting effects and pixel-level control. These 24V strips typically offer high CRI (e.g., Ra>90) and uniform illumination due to the absence of visible LED dots. Available in various power densities, they are suitable for architectural accent lighting, retail displays, and entertainment applications requiring precise light sequencing and color manipulation. Custom lengths and IP ratings are available to meet specific project requirements.

Addressable SPI COB LED Strip — Buyer Questions

What is an SPI addressable COB LED strip?

An SPI COB LED strip is a dot-free tape with a driver IC controlling each addressable segment, so chasing, gradient and running-water effects play across a continuous line instead of a row of visible pixels. DENO builds addressable COB boards at 24V with WS2811-class and UCS-class ICs, segment lengths specified per project.

Which IC should an addressable COB LED strip use?

Pick by control system and segment length: WS2811/WS2812-class ICs suit standard SPI controllers and short segments, UCS2904-class ICs add a fourth channel for RGBW effects, and constant-current ICs keep brightness identical along a long run. Tell DENO the controller you use and the IC is matched to it.

How smooth is a chasing effect on a dot-free strip?

Much smoother than on SMD pixel tape. Because the phosphor line is continuous, a moving segment reads as a travelling band of light with soft edges, not a series of switching dots — which is why stage, KTV, club and signage projects specify addressable COB for slow gradients and running-water sequences.

How far can an SPI COB LED strip run before data or power injection?

Plan power injection every 5 m at 24V and follow the IC's data-length limit, typically 5–10 m per data line before a repeater. Data errors usually show as a flickering tail, so specify the run length up front and DENO pre-plans the injection points on the drawing.

Can addressable COB tape be driven from DMX or Art-Net?

Yes, through an SPI decoder. DMX512 and Art-Net controllers convert to the SPI protocol the strip expects, which is the normal route for stage and architectural media installations that need the dot-free line to sit inside an existing lighting network.

Frequently asked questions

What are the primary advantages of an SPI addressable COB LED strip compared to standard COB strips?

An SPI addressable COB LED strip offers individual pixel control, enabling dynamic lighting effects such as chasing, fading, and complex patterns. Standard COB strips provide uniform, static illumination across their entire length. The addressable nature allows for greater design flexibility and interactive lighting installations, controlled via a dedicated SPI protocol.

What control protocols are compatible with DENO LED's SPI addressable COB LED strips?

DENO LED's SPI addressable COB LED strips typically utilize standard Serial Peripheral Interface (SPI) protocols, such as WS2812B, WS2811, SK6812, or similar ICs. Compatibility depends on the specific IC integrated into the strip. Users should verify the IC type to ensure proper integration with their chosen SPI controller for sequence programming and effect generation.

What considerations are critical for power supply and voltage drop when installing SPI addressable COB LED strips?

Adequate power supply capacity is crucial, as each pixel consumes power independently. Voltage drop must be managed, especially over longer runs, to ensure consistent brightness and color accuracy across the entire strip. It is recommended to inject power at multiple points or use shorter segments to mitigate voltage drop effects, particularly for 24V systems.

Can SPI addressable COB LED strips be customized for specific project requirements, such as length or IP rating?

Yes, DENO LED offers OEM/ODM services for SPI addressable COB LED strips. This includes customization of strip length, LED pitch, pixel density, and various IP ratings (e.g., IP20, IP65, IP67) to suit diverse environmental conditions. Project-specific requirements for color temperature, CRI, and power density can also be accommodated upon request.
