LED Lighting - COBs, Engines, Modules

LED lighting products are becoming more and more popular. With their superior energy efficiency, durability, and long lifespan, LED light fixtures are quickly overtaking traditional lighting solutions. Among these LED lighting solutions are COBs, engines, and modules. Understanding the applications and workings of these different lighting components is essential for anyone looking to purchase LED lighting.

What Is a COB?

COB stands for chip-on-board. This type of LED lighting features multiple LED chips directly mounted onto the substrate of a circuit board. This method is often used when creating direct replacements for traditional lighting fixtures, such as recessed cans and downlights. Compared to other types of LED arrays, COBs are more cost-effective and offer higher efficiency. A common COB product is the JDHT8R-A0240-8020-S00-NSA. This particular COB has a color temperature of 4100K and an efficiency of 80 lm/W.

What Is an LED Engine?

An LED engine is essentially a self-contained unit of LED chips, lenses, heatsink, and driver all combined together. This makes them the most efficient and easiest way to incorporate high-quality LED lighting solutions into any space. While they are more expensive than other solutions, they drastically reduce installation costs as they come pre-assembled and require only basic wiring instead of complicated soldering and drilling.

What Is an LED Module?

An LED module is a replacement for traditional lighting fixtures like downlights and panel lights, with the addition of a driver. These modules are typically built into recessed can housings, or attached to panels or frames. The driver allows for easy dimming and control options of the lighting, either through a switch or via a smart device. LED modules are a great option for creating LED lighting solutions in areas where dimming and control is desired, such as in bedrooms or living spaces.

Working Principle of LED Lighting

LED lighting works through a process called electroluminescence, where electrical energy is converted into visible light. This is achieved by passing current through a semi-conductor, which causes the electrons to move around in a certain way, producing light. By varying the current, the amount of light emitted can be controlled. This makes LED lighting ideal for applications where dimming or control is desired.

Conclusion

LED lighting is quickly becoming the preferred choice for illumination due to its superior efficiency, durability, and lifespan. Among the various LED lighting solutions available are COBs, engines, and modules, each of which have their own unique applications and working principle. Understanding the features and uses of all three types is essential for anyone looking to purchase LED lighting.
