LED lights are popular because they have longer lifespans and are more efficient than traditional bulbs. LED lights are also safer and need less maintenance than conventional types of lighting. However, not all LED lights are the same. COB and SMD LED

LED downlights are classified into two types: chip on board (COB) LEDs and surface mount diode (SMD) LEDs. Both of these downlight systems create high-quality light and can be relied on to last a long time and operate wonderfully. They do, however, have different benefits over one another.

Here’s an explanation of the differences between SMD and COB LEDs, as well as whether one could be best for your home or business. 

What are COB LED Strips?

Because all of the LEDs in the light are concentrated in a single place, the COB LED strips have a mounted LED chip that need additional cooling capacity. As a result, a big heat sink will be present in the region to disperse the heat. The COB LED may be slightly more expensive than an SMD LED due to the increased expense of a heat sink.

COB chips often have 9 or more diodes. COB chips feature only one circuit and two connectors, regardless of the number of diodes. Because of its basic circuit design, COB LED lights have a panel-like appearance. COB LED lights, on the other hand, cannot be utilised to make color-changing lights, unlike SMD LED lights. This is because there are just two connections and one circuit.

COB lights are frequently utilised in single-color applications, however they are not found in more diversified technologies.

What are SMD LED Lights?

An SMD LED strip produces 50-100 lumens per watt, which means you’ll get more light while using less power. Despite the fact that a COD LED strip is more efficient, SMD LED lights are more efficient in terms of brightness.

Because SMD LEDs provide a broader light beam, they do not require as big a heat sink as COB LEDs. As a result, SMD LEDs may become more affordable. These lights also include frosted reflectors that enable for even light dispersion while concealing the chip array inside the bulbs.

SMD LED chips come in a range of sizes. SMD LED can handle chips with elaborate patterns, such as the SMD 5050 LED strip, which is 5mm wide. The SMD 2835 LED strip, on the other hand, is 2.8mm wide.

SMD chips are small and almost equivalent to flat, square computer chip design. When comparing COB versus SMD lights, one of the defining features is the amount of connections and diodes on SMD LED chips. SMD chips feature more than two connections and up to three diodes, each with its own circuit.

When comparing COB LED vs SMD LED, the arrangement of SMD chips makes them more adaptable. The SMD chip has three types of diodes: red, green, and blue, which may be combined to produce nearly any colour by altering the output level.

Why Should You Choose The COB LED?

In general, COB LED lights are higher-quality light sources. This is because they employ reflectors to create concentrated and controlled light. They also do not have the frosted lenses that are customary with SMD LED lights. As a consequence, the illumination should be brighter and clearer. Because of this, COB LED lights are quite beneficial in high-ceilinged places.

COB LEDs are higher-end LED lights with a more architectural appearance; if you intend to live with your LED downlights for an extended period of time, a COB LED strip is the way to go. SMD lights will suffice if you’re installing LED strips in an investment property.

Why Should You Choose SMD LED Lights?

As previously said, SMD LED lights are an excellent choice if you want your light to cover a large area. You may use them to provide bright lighting in restrooms, kitchens, and bedrooms. When comparing LED COB versus SMD lights, the SMD lights exhibit higher glare and have a stronger impact in low-light conditions.

Difference Between COB and SMD Lights

Production Efficiency

SMD LED light production efficiency is poor when compared to COB LED light production efficiency. COB lights save electricity since they generate less lumens per watt.

Light Source Quality

An SMD is a type of point light created by merging several point power supply. For point light and glare, discrete SMD devices are available. A surface light, on the other hand, is referred to as a COB. The light is more uniform, there is no halo, and the COB angle beam is simple to change. When comparing COB lights to SMD lights, there is no spotlight or glare.

Productive Process 

SMD: The SMD LED chip is constructed of conductive and insulating glue that is put to the pad of the lamp bead holder and then welded with the same conductivity as the COB package. It is enclosed in epoxy resin and separated, cut, and taped after passing the performance test before being shipped to the screen manufacturing.

COB: The COB LED chip is directly attached to the pad of the lamp bead lamp position of the PCB board with conductive glue and insulating glue, and then the LED chip’s conduction performance is soldered.

Cost

SMD lamp beads: Labor and manufacturing costs account for approximately 15% of the material cost of typical SMD lamp beads.

COB lamp beads: Labor and manufacturing costs account for about 10% of the material cost of COB-LED lamp beads. Using COB LED lamp beads, labour and production expenses may be lowered by 5%.

Color Temperature Options

With bespoke led lights, the structural physical features of SMD can meet a number of colour temperature possibilities, whereas COB is often a single colour temperature.

Practical Application

Based on the COB vs SMD LED for growth differences, the actual use of COB and SMD lights is determined by the luminance and colour temperature options that they provide. The SMD 2835 led strip is used to brightly brighten dark regions. It is commonly utilised in architectural constructions to accentuate architectural elements.

COB LED lights are long-lasting at extreme temperatures, making them an ideal choice for street lighting and industrial lighting.

Which Led is Better and Brighter?

Determining which LED light is superior between COB and SMD will necessitate taking into account three determining variables, which are:

Energy Conservation

In general, working with LED lights should result in significant energy savings. As a result, unlike filament bulbs, they are gaining popularity and becoming the preferred light source.

Keeping this in mind, you can be confident that both SMD and COB LED will be incredibly energy efficient. It is critical to note that the quantity of energy used will vary depending on the lumens utilised. The higher the lumen count, the more energy-efficient the gadget.

Cost-Effectiveness

LED lights are less expensive than other types of lighting. They are engineered to last longer and use less energy than competitors. You’ll have to make an initial investment that may be a little more than normal, but it’ll be well worth it. SMD LEDs will be more expensive to manufacture than COB LEDs.

Brightness

The lumens produced by the chips in question have a significant influence on the brightness. LED lights, in general, provide a brighter light than conventional light sources. Because they have a larger lumen, this is the case.

A lumen per watt measurement of 50 to 100 is utilised for SMD LED. This means that even at high brightness levels, less energy is consumed. COB, on the other hand, has a higher lumen output than SMD. The most basic criteria is 80 lumens per watt. This raises the brightness and quality of COB-powered lighting.

Conclusion

There’s no doubting that LED lights exceed other light sources in terms of performance and energy economy. This is why it’s vital to accept them if you want to maximise your possibilities while also selecting the finest manufacturer.

If you’ve been trying to figure out what COB and SMD are, maybe this article has cleared everything out for you. Both of these solutions are wonderful investments that function in the same way to keep the lights on.
