Core Features

Why COB Delivers a Flawless Light Line

Six engineering advantages built into every Helian COB strip.

01

100% Seamless Light

Chip-on-board packaging produces a continuous, dot-free light line — no hot spots, even in shallow profiles under 6mm.

02

High CRI Consistency

CRI >90 with SDCM <5 binning — uniform, museum-grade color rendering across every reel and batch.

03

IP65 Waterproof

Silicone-coated to protect against moisture — rated IP65 for bathrooms, kitchens and wet zones.

04

Short Cutting Pitch

Precision cut points every 25mm or 50mm, with solderless connectors for fast, tool-free field installation.

05

High Luminous Efficacy

Up to 119.8 lm/W delivers more usable light per watt — lowering energy cost across large installations.

06

Ultra-Slim PCB 4–14mm

Four PCB widths from 4mm to 14mm fit recessed, surface and corner channels — from cove to task lighting.

The Technology

The Evolution of Linear Lighting:
COB vs. Traditional SMD

Traditional SMD strips mount discrete chips, leaving visible dots. Helian’s flip-chip COB packages LEDs directly onto the substrate for a dense, uniform light line.

Traditional SMD Strip

STD.
Dotless
Visible LED dots — requires deep diffuser covers to hide individual chips.
Uniformidade
Visible chip spacing creates dark zones and uneven light between LEDs.
Flexibilidade
Wire-bonded chips prone to micro-fractures at tight bend radii.
Color Quality
CRI 80–90 typical. Visible color shift under low-light conditions.
Light Line

Helian COB Strip

RECOMMENDED
Dotless
100% continuous light line. No hot spots, even in <10mm shallow profiles.
Uniformidade
Continuous emitting surface — zero dark spots, even in shallow profiles.
Flexibilidade
Flip-chip packaging with zero wire bonding for superior bending durability.
Color Quality

ANSWER · TECHNICAL

COB packages flip-chips directly onto the PCB, creating a dense, continuous light with zero hot spots. SMD strips mount discrete LEDs with visible spacing, producing visible dots.

ANSWER · INSTALLATION

While COB LEDs generate heat evenly, we strongly recommend pairing strips with aluminum profiles for any product rated above 10W/m. Aluminum channels maximize thermal dissipation, extend lumen maintenance, and provide a clean finished look.

ANSWER · QUALITY CONTROL

We enforce strict single-binning protocols with SDCM < 3 (3-Step MacAdam Ellipse) to ensure perfect color uniformity across every production lot. Repeat orders can be matched to the original batch’s bin code.

ANSWER · FIELD USE

Yes — designated cut points are clearly marked on the PCB (typically every 25mm or 50mm). We supply solderless quick-connectors and snap-on terminal blocks for tool-free installation. For IP-rated strips, our silicone end-caps restore full protection after cutting.
