1. What Is a COB LED Strip?
- Definition: A type of LED strip where multiple LED chips are densely packed and mounted directly onto the circuit board.
-Key Feature: COB LED strips produce a continuous, seamless line of light without the "dot" effect of traditional LED strips.
2. Why Do COB LED Strips Look Yellow?
a) Phosphor Coating
- Reson: he yellow appearance comes from the phosphor layer that coats the LED chips.
- Purpose: The phosphor converts the blue light emitted by the LED chips into white light, creating a warmer or cooler color temperature.
- How It Works: When the strip is off, the yellow phosphor layer is visible, but when turned on, it transforms the blue light into the desired white or colored light.
b) Importance of Phosphor in Light Quality
- Role of Phosphor: Helps ensure smooth, uniform light output and accurate color rendering.
- Color Temperature: The type of phosphor coating used affects the final light temperature (e.g., warm white, cool white).
3. Does the Yellow Color Affect Lighting Performance?
- No Impact on Light Output: The yellow appearance is only visible when the strip is off.
- Bright, Seamless Lighting When On: Once powered, the strip emits smooth, high-quality light with no yellow tint.
- Professional Applications: Ideal for installations requiring continuous lighting, such as architectural and cove lighting, due to its even distribution and minimal gaps.
4. Benefits of COB LED Strips
- Uniform Light Output: No visible dots or dark spots.
- High Brightness: Excellent for task lighting and professional installations.
- Better Heat Dissipation: Improves lifespan and efficiency.
- Modern, Sleek Design: Even when off, the strip has a clean, modern look.
