Improvements to LED lighting are made all the time to make them easier to operate, more versatile, and more power-efficient.Because they may last up to 25 times longer and consume less energy than conventional incandescent lights, LED lights are very popular.
LED light sources come in a variety of models, but the two most popular package types are SMD and COB. You can choose COB or SMD LED lights based on your needs by first understanding the benefits and distinctions of each type of light.
COB and SMD COB advantages
low rate of production failure.
reduces energy use while producing more lumens.
more effective heat conductivity. Chip distance is reduced as a result, and space is conserved.
Due to the flexibility of the circuit and the more practical heat dissipation, it is possible to successfully avoid the drawbacks of a discrete light source device's combination of light gathering and glare.
SMD
high levels of vibration resistance and dependability.
Enhance production effectiveness and lower the number of faulty solder joints.
SMD is more adaptable; its chip's display can be altered to conform to various engineering solutions depending on how the printed circuit board's layout dictates.
The illumination angle of SMD light sources is greater, ranging from 120 to 160°.
LED light differences between SMD and COB
COB
Better thermal efficiency and lumens/W are two advantages of COBs.COB chips can generate at least 80 lumens per watt while using less energy.
Typically, COB chips feature nine or more diodes. In addition, COB chips contain 1 circuit and 2 connections regardless of the quantity of diodes. The panel-like structure of COB LED lights is produced by this straightforward circuit design.
Due to the fact that there are only two contacts and one circuit, COB LED lights cannot be utilized to create color-changing bulbs or lamps. Additionally, to achieve the color-changing effect in color-changing bulbs, various channel changes are needed. COB LED bulbs therefore perform better in monochromatic applications than in general-purpose technology.
SMD
SMD chips have a reputation for brightness and have a lumen output of 50 to 100 per watt.
SMD LED chips can include up to three diodes, each with its own circuit. There are 2, 4, or 6 contacts in a chip for each circuit's cathode and anode, depending on the circuit.
Because of this alignment, SMD chips are more adaptable than COBs. Diodes in the chip could be red, green, or blue. By altering the output level of these three diodes, you may produce any hue.
Conclusion
In conclusion, SMD and COB are both used in a variety of applications. However, SMD is largely tailored to the requirements of different LED lights. Depending on the precise needs of the application, you can pick between SMD or COB varieties of LED lamps.
