E27 LED Light Bulb 4W COG Clear

In COG technology (Chips on Glass), the LED chips are directly mounted onto the glass of the LED screen or module, rather than on a traditional Printed Circuit Board (PCB) as in other mounting methods. This has several advantages:

Compact and Thin Design: By mounting the LED chips directly on the glass, the design of the LED module becomes significantly more compact and thinner. This allows manufacturers to produce slimmer and lighter LED products.

Improved Heat Dissipation: The heat generated by the LED chips can be more efficiently dissipated to the glass, helping to maintain a lower operating temperature. This contributes to better reliability and lifespan of the LED lighting.

Better Light Uniformity: COG technology can contribute to better light uniformity as the LED chips are placed directly on the glass. This minimizes shadows and improves light distribution, resulting in more consistent brightness across the surface of the LED screen.

Simpler Manufacturing Process: The production of COG LED modules can be simpler compared to traditional PCB-based methods, potentially reducing production costs.

Possibility of Greater Flexibility: COG technology allows for the production of LED lighting in various shapes and sizes, providing manufacturers with more flexibility in designing custom solutions.

Overall, COG offers several benefits in terms of design flexibility, heat management, and light uniformity. It is often applied in situations where thin and lightweight LED products are important, such as in certain types of displays or decorative lighting.
