وصف المنتج
What is COB?
COB stands forChip-on-Board. It is an advanced packaging technology where multiple tiny LED chips (often hundreds per meter) are directly mounted and bonded onto a flexible printed circuit board (FPCB), then coated with a uniform phosphor layer. This creates a single, continuous lighting module, as opposed to the discrete, spaced-out "dots" of light found on traditional SMD (Surface-Mounted Device) LED strips.

Key Features & Advantages:
1. Perfectly Uniform Light: The most significant benefit. It eliminates the "dotting" or "spotty" effect, producing a smooth, seamless light line without any visible individual LEDs, even when viewed directly.
2. High Density & Brightness: The extreme miniaturization and dense packing of chips allow for very high lumen output in a compact form factor.
3. Excellent Color Consistency: The single phosphor coating over multiple chips ensures a consistent color temperature and chromaticity across the entire strip, with minimal color deviation (low CCT/CRI variance).
4. Enhanced Durability: With fewer soldering points and a robust encapsulated structure, COB strips are more resistant to vibration, moisture ingress (typically rated IP20 to IP67), and physical damage.
5. Improved Heat Management: The design allows for more efficient thermal transfer from the chips to the aluminum channel or heatsink, potentially extending the product's lifespan.
6. Flexible & Slim Profile: They remain highly flexible and come in very narrow widths (e.g., 2mm-6mm), enabling installation in tight spaces and around curves.

Comparison with SMD Strips:
· Beam Angle: COB strips have an ultra-wide beam angle (typically up to 180°), providing even side illumination, whereas SMD strips have a more directional beam.
· Visual Effect: Seamless "light line" vs. distinct "light dots."
· Cutting Units: COB strips often have smaller cutting increments (e.g., every 1-2 LEDs or per 25-50mm) for greater design flexibility.

Typical Applications:
· Architectural Lighting: Cove lighting, under-cabinet lighting, stair riser lights, handrail illumination.
· Commercial Display: Museum case lighting, retail shelf accent lighting, product highlighting.
· Automotive & Interior Design: Decorative lighting in vehicles, home decor, furniture-integrated lighting.
· Task Lighting: Kitchen countertops, workbenches, where shadow-free, even light is crucial.
· Aesthetic Projects: Creating sharp, continuous lines of light in modern minimalist designs.

Considerations:
· Heat Dissipation: For high-power COB strips, proper installation on an aluminum profile or heatsink is essential for performance and longevity.
· Driver Compatibility: Require a constant voltage LED driver (e.g., 12V/24V DC). Dimming requires a compatible PWM or constant current dimmer.
