Lighting with LED technology has come to replace the use of incandescent and fluorescent light bulbs, thanks to its great advantages. Due to its great popularity and efficiency, various types of LEDs have emerged, such as COB and SMD LEDs, which, despite belonging to the same technology, have significant differences.

What are SMD LED lights?
The SMD (surface mount device) LEDs are encapsulated in a semi-rigid resin assembled superficially and are usually indicated to be placed in passageways or where the lighting is not going to be continuous. It provides a dimmer light to prevent the led chip from reaching high temperatures.

What are COB LED lights？
The COB is an abbreviation for chip-on-board LEDs. COB LEDs have a multitude of LEDs inserted in the same encapsulation. Due to their mounting method, they dissipate heat better, so they can withstand being constantly on and are recommended for workplaces, for example, offices, banks, etc.

Difference between COB and SMD lights？
Types

The SMD Led has various types, such as 5730, 5630, 5050, 3030, 3014, and 2835. Every type is named according to the measurements based on the width and length.
The types of COB LEDs are limited. They are 1W or 5W.

Usages
They are not designed to be continuously on due to overheating. They are used in places where dim light is needed, such as bedrooms. Different models have different usages, such as SMD4014 is mainly used in LED panel light, and SMD2835 is primarily used in LED batten light.
They are suitable for spaces where light is needed for many hours, for example, workplaces, offices, workshops, etc.

Brightness
SMD LEDs Light output is between 60 and 70 lumens per watt, and Light opening angle of up to 360 degrees. They emit unidirectional light only that’s why they provide dimmer light.
The light output of COB LED is up to 120 lumens per watt, twice that of SMD bulbs. The opening angle of up to 160º, but with multidirectional light and without glare. COB LEDs provide higher Brightness to the room.

Heat dissipation
COB construction is based on a set of LEDs in the same package, whose material dissipates heat better. The duration of the COB LED bulb is longer than SMD due to less heat generated. It has greater durability by not needing an electrical circuit for its operation.

Cost
In terms of prices, today, COB LEB bulbs are somewhat more expensive than SMD, but it seems that this will change little by little with technological advancement.

Which LED is Better and Brighter?
COB LEDs and SMD LEDs are both good options as they are at the forefront of LED technology, but each one meets the appropriate conditions for a specific use. Still, In COB LED bulbs, capacity and light output are more than double that of SMD LED bulbs, so they are brighter than SMD LEDs. These lights are recommended for installation in areas that need more light. The capacity of the COB LEDs is 120Lm/W which provides high light intensity. Always keep in mind that try to get LED that is bright enough for usage area, either at work or at home.

Conclusion
Despite this, and derived from all these aspects, some LED luminaires can provide more significant benefits. The COB and the SMD LED have different characteristics, which are worth highlighting to obtain a better result in the projects you want to carry out. COB LED technology will always guarantee a long lifetime and lighting quality, achieving significant economic and energy savings.
