## Answer.

### What is cob LED?

Chip-on-board (COB) LED is a type of LED where multiple LED chips are mounted directly onto a substrate to form a single module. This design allows for a higher light output and better thermal management compared to traditional individual LED package.

### What are the key specifications of cob LED?

1. **Power:** The power rating of a cob LED indicates the amount of electrical power it requires to operate and the level of light output it can produce.

2. **Color Temperature:** This specification defines the color appearance of the light emitted by the cob LED, measured in Kelvin (K).

3. **CRI (Color Rendering Index):** The CRI of a cob LED indicates how accurately it can reproduce colors compared to natural light. A higher CRI value signifies better color rendering.

4. **Luminous Flux:** Luminous flux measures the total amount of visible light produced by the cob LED, expressed in lumens.

5. **Forward Voltage:** This is the voltage required to operate the cob LED and is crucial for determining the power supply needed for the lighting system.

6. **Viewing Angle:** The viewing angle of a cob LED determines the spread of light emitted and influences the lighting distribution pattern.

7. **Operating Temperature:** The operating temperature range specifies the environmental conditions in which the cob LED can function optimally.

### Why are these specifications important?

- **Performance:** Understanding the key specifications helps in selecting the right cob LED for specific lighting applications to achieve desired performance levels.

- **Energy Efficiency:** Specifications such as power, luminous flux, and forward voltage impact the energy efficiency of the cob LED, leading to cost savings.

- **Light Quality:** Color temperature, CRI, and viewing angle determine the quality of light output, influencing the visual appeal and functionality of the lighting.

In conclusion, the key specifications of cob LED play a crucial role in determining its performance, energy efficiency, and light quality, making them essential considerations when selecting cob LEDs for various lighting projects.
