High power COB LED, also known as high power chip-on-board LED, has become a popular choice in the lighting industry due to its superior performance and efficiency. This article will provide an in-depth introduction to high power COB LED, covering its characteristics, applications, advantages, and future development trends.

Introduction to High Power COB LED

High power COB LED is a type of LED that integrates multiple LED chips onto a single substrate. The substrate is usually a sapphire, silicon carbide, or silicon wafer. The chips are then bonded to the substrate using a die attach process, followed by encapsulation with a transparent material to protect the LED chips and enhance their light output. Compared with traditional LED packages, high power COB LED has several distinct advantages. Firstly, it offers a higher luminous intensity, which is crucial for applications requiring high brightness, such as street lighting, industrial lighting, and large-scale outdoor advertising. Secondly, high power COB LED has a more compact size, allowing for better heat dissipation and reducing the overall system volume. Lastly, it boasts a longer lifespan and lower power consumption, making it an environmentally friendly and cost-effective solution.

Characteristics of High Power COB LED

1. High luminous intensity: High power COB LED can achieve a luminous intensity of up to 5000-10000 lm/W, which is significantly higher than traditional LED packages. 2. Compact size: The integrated design of high power COB LED reduces the overall system volume, making it ideal for space-limited applications. 3. Excellent heat dissipation: The compact structure of high power COB LED ensures efficient heat dissipation, preventing overheating and extending the lifespan of the LED. 4. Long lifespan: High power COB LED has a lifespan of up to 50,000 hours, which is twice as long as traditional LED packages. 5.
