What is K-COB?

K-COB features a unique LED packaging design that replaces the conventional organic materials such as epoxy or silicone, with phosphor ceramic.

Consist of KCOB

It is a phosphor ceramic specifically designed for LED applications;

Patented ”Dual channel heat sinking’ structure: the thermal resistance of phosphor ceramic is significantly lower than traditional epoxy and silicone molding, which enables heat dissipation from both ceramic and PCB effectively.

The solid ceramic surface provides good impact resistance for the LED chips and facilitates the assembly of lamps.

1.Optical Design

  • Optical Lenses: COB lights usually require secondary optical design, such as adding lenses or reflectors to control light distribution and angle. Selecting appropriate lens materials and shapes can enhance light efficiency and meet specific application needs.
  • Uniform Light Output: The light spot of a COB light source is more uniform, reducing multi-shadow effects. Therefore, in optical design, further optimization of light uniformity can improve lighting quality.

2. Thermal Management

  • Heat Dissipation Design: COB lights generate significant heat during operation, so effective thermal management is crucial. The choice of heat sink material and structure should be based on power and application environment, such as using high thermal conductivity aluminum or copper materials and designing suitable heat dissipation fins and thermal pathways.
  • Thermal Conductive Materials: Between the COB chip and the heat sink, use high thermal conductivity materials like thermal conductive glue, thermal grease, or thermal pads to ensure rapid heat transfer, avoid chip overheating, and extend the lifespan of the light.

3. Driver Power Supply

  • Constant Current Driver: COB lights typically require constant current drivers to ensure stable light output. The driver power supply should include overvoltage, overcurrent, and overtemperature protection to enhance product reliability and safety.
  • Dimming Functionality: To adapt to various lighting scenarios, integrating dimmable drivers that support PWM, 0-10V, and other dimming methods allows COB lights to have flexible brightness adjustment capabilities.

4. Structural Design

  • Encapsulation Materials: Use high-quality encapsulation materials, such as waterproof and dustproof LED encapsulation adhesives, to improve the lamp’s weather resistance, making it suitable for outdoor and harsh environments.
  • Housing Design: The lamp housing should have good protection features such as waterproof, dustproof, and corrosion resistance. At the same time, consider the aesthetic design to meet the needs of different markets.

5. Electromagnetic Compatibility (EMC)

  • Electromagnetic Shielding: Ensure that COB lights do not experience or cause electromagnetic interference during use by designing good electromagnetic shielding measures, including shielded cables and shielding covers.
  • Filter Circuit: Design a reasonable filter circuit to suppress high-frequency noise in the power supply, improve EMC performance, and comply with relevant standards and certification requirements.

6. Application Scenarios Optimization

  • Indoor Lighting: For indoor applications, COB lights can be used in downlights, spotlights, panel lights, etc. It’s necessary to optimize color consistency and uniformity of the light spot.
  • Outdoor Lighting: For outdoor applications, COB lights can be used in street lights, floodlights, etc., requiring enhanced waterproof and dustproof designs, higher brightness output, and a wider lighting range.
  • Commercial Lighting: In commercial environments, COB lights can be used in shopping malls, exhibition halls, and similar venues, emphasizing high color rendering and comfortable lighting environments.

7. Intelligent Control

  • Smart Dimming: Combine with intelligent control systems to achieve remote adjustment of lamp brightness and color temperature, enhancing ease of use and energy efficiency.
  • Human Sensing Technology: Integrate human sensing or light sensing modules so that COB lights can automatically adjust brightness based on ambient light or human activity, further saving energy.

8. Certification and Standards

  • Safety Certification: Ensure that the product meets local market safety certifications such as CE, UL, etc., to enhance market competitiveness.
  • Energy Efficiency Certification: Improve the lamp’s energy efficiency indicators to meet energy standards like Energy Star.
