Why LED Chip-on-Board?
- Cost-effective alternative to incandescent and fluorescent light sources
-
- Increased life span and efficiency
- System integration, no user-serviceable parts
- The reduced total cost of ownership
- Customised array size and shape
- Application-specific wavelengths
- Chip-on-board vs. surface mounted LEDs:
- Low-pitch / higher density arrays
- Improved efficiency and heat dissipation
- No over-moulding material boosts light output
- Fewer interconnects reduce reliability risk
