COB VS SMD

LED lights are constantly improved to bring about better use, greater versatility and more efficient use of power. The different models of LED lights are highly popular compared to traditional incandescent lights, mainly because they can last for about 25 times longer with less energy use.

LED lights come in a variety of models. Start comparing COB vs SMD LED Lights, or before you look at the difference between LED light COB and SMD.

You can choose between SMD vs COB types, for example, depending on your needs for energy efficiency and versatility. The COB vs SMD LED Lights differ in terms of their features and semiconductors.

A SMD LED  (surface-mount device light-emitting diode module) is a type of LED module that uses surface-mount technology.

A COB or ‘chips on board’ light is a type of led package. In COB lighting, single LED chips are placed directly on a circuit board (or substrate) which has thermal properties to disperse heat.

LED’s which are used on LED strip are SMD’s.

SMD vs COB: What is SMD?
SMD, or “Surface Mounted Device” LEDs, are the most common LEDs in the market. The LED chip is permanently fused to a printed circuit board, and it’s highly popular due to its versatility. You can find it in light bulbs and string lights, and even in the notification light on your mobile phone.


The SMD LED chips come in a variety of sizes. SMD LED can accommodate chips with complicated designs, like the SMD 5050, which is 5mm wide. The SMD 3528, on the other hand, are 3.5mm wide. The SMD chips are small, almost close to the design of the flat, square computer chip.

SMD vs COB: What is COB?
One of the most recent developments in LED, COB or “Chip on Board” technology is a step forward more efficient energy use.Like the SMD, COP chips also have multiple diodes on the same surface. But the difference between LED light COB and SMD is that COB LEDs have more diodes.


COB chips typically have 9 or more diodes. COB chips also only have 1 circuit and 2 contacts, regardless of the number of the diodes. This simple circuit design is the reason for the panel-like appearance of COB LED light (SMD light, on the other hand, appears like a collection of smaller lights).

But unlike SMD, COB LED lights can’t be used to create colour changing bulbs or lights. This is because there are only 2 contacts and 1 circuit. Multiple channels for adjustment are required to create the colour changing effect. Because of this, COB LED lights are efficient in single-color applications, but not in more versatile technology.
