COB Means What?
What is COB?
COB is short for Chip On Board, which means that the chip is directly packaged on the PCB.
The COB light strip is a light strip that encapsulates the chip on a flexible board. Chips mostly use flip-chips, which are linearly solid-bonded on the PCB, and then a layer of packaging glue mixed with phosphor is directly dropped on the surface of the chip. The light emitted by the chip is refracted, reflected, and interacted with the phosphor inside the encapsulating gel. The gel uniformly emits light of different colors and color temperatures.
it is a new type of process technology, based on the SMD led strips with further evolution. In order to facilitate your understanding, I drew a side sectional view.
What is Internal Instructure for COB/SMD Led Strips?
SMD LED Strips
so on the same length PCB board, COB type light strips There are more chips that can be arranged, and the density is higher. One meter can reach 1000 or even 2000 pieces of chips. The brightness and uniformity of those COB led strips far exceed the SMD led strips.
Compare to COB LED Strips and SMD LED Strips
Let's light it up and see the comparison.
The COB led strips have a linear light-emitting surface due to their high chip density, while the SMD led strips can see obvious light spots and dark areas. Of course, this dark area and light spot can be solved by adding aluminum profiles and diffusers, just like this.
And COB light strips can become very uniform without adding diffuser. In this way, a lot of material costs and labor costs can be saved.
However, the aluminum profile is not completely useless on the COB led strips, it can play a role in fixing the shape and protecting the led strips.
There are also hundreds of different styles of aluminum profiles, which are suitable for different installation methods and different application scenarios. You can find these on the YIFORD website and catalogue.
---------------What are the features of COB soft led light strip?--------------------
When introducing the structure of the COB led strips, you may have realized that the most obvious feature of the COB led strips is that it emits uniformly, without bright areas and dark spots, and has good overall consistency, soft and non-glaring.
This is why more and more customers like to buy Yiford COB light strips.
What effect can the high color rendering index bring to the illuminated object?
Let’s take a look at this comparison chart. Under the illumination of this high color rendering index COB light strips, the illuminated object has richer colors and color gamut. More extensive, more visible parts, more obvious details.
Therefore, Yiford COB soft light strips are widely used in instrumentation, monitoring, machine, museums, jewelry, kitchens, fresh food stores, display areas, and so on.
What is Color Rendering Index and Why Choose it Important | Understanding CRI:
Of course, my operation demonstration is an extreme test. It is not for you to use it like this. It is just to show you the folding resistance of the Yiford COB light strip. It is indeed very soft and can withstand stronger distortion.
In actual use, please use the COB light strip under the instruction manual. great flexibility function allowing you to obtain the shape you need.
With the strong adhesive, the cob led strips are easy to install in narrow places. such as modeling, advertising, luminous signs, contours and so on.
Measurement The required length first. Then find the place where the COB led strips is closest to the required length, cut it along this cutting line and it can be used alone, which greatly facilitates the DIY project.

There are two ways to connect, one is to connect the solder point of the two light strips with an electric soldering iron and welding wire, and the other is to use Yiford solder-free connector.
This crystal connector has a built-in metal pin. Just press the metal pin to the solder On the solder point, the two light strips can be energized and connected. After the connection is made, there is almost no gap in the middle. At the same time, because the crystal connector is transparent, it is almost impossible to see the connector in the middle after lighting up. The effect is supergreat. click here to watch video for how to use the cob led strips connector
For connection methods and accessories indication, please watch Yiford’s video "How to cut and connect COB soft light strips". Without any fixture, the light strips can be connected in a few seconds, which is durable and effective.
You see, the COB light strip is very thin, with a thickness of only 2 mm, which is 1/16 inch. It can be easily installed in a small space and can be easily hidden. Whether it is a large project or a small product, it is inseparable from the assistance of light.
Many times we hope to add some light to the object without increasing the size of the object itself, or hope that the light will not be directly seen.
For example, if you install COB led strip into furnishings or wall murals, it is very easy to hide it, you can't see the light strips, only the light. Isn't it very easy to use?
Colorful colors create a colorful world. We cannot live without a variety of colors, red, green, blue, yellow, purple, pink, etc. Yiford company provides COB in a variety of colors of Light strips, and there are turnable white changeable， colorful changeable， pixel controlled programmable strips， etc.,
With Yiford LED controller and dimmer, the color of the COB light strip is more extensive. With these COB light strips of different colors, I believe you will easily find the light color you like, and you don't have to worry about matching colors anymore.
Below are the videos for the single color and mutil color led strip lights. you will understand each color's effect:
It’s really smart to adjust what kind of lighting you like.
You can rest assured that the light-emitting area of the COB soft light strip is relatively large, and the ordinary COB led light strip can achieve 1,000 lumens per meter, or even as high as 2,000 lumens per meter.
Whether it is used on ceilings, walls, floors, interior, and exterior use, no matter for decoration or lighting, it is a very good choice.
For the application of led strip lights, recommend read:
What are application ideas for LED Strip Lighting?
For example, the brightness of a 13-watt LED bulb is equivalent to that of a 100-watt ordinary incandescent lamp, and its life span is 10 times that of an ordinary incandescent lamp, and can be used for more than 10 years. Using COB light strips instead of traditional incandescent or fluorescent lighting can save a lot of energy and electricity bills.
At the same time, the materials of the COB led light strip, whether it is PCB or lamp beads, are environmentally friendly materials and can be recycled.
It does not contain harmful substances such as mercury and lead, does not contain ultraviolet rays and infrared rays, safer for your eyes will not cause pollution and damage to the earth, and is environmentally friendly and healthy.
The installation of the COB soft light strip is also very simple. It comes with double-sided adhesive. After tearing off the adhesive, it can be pasted and used.
The stickiness is also strong, such as plastic board, wood board, cardboard, glass, metal, and other smooth and clean objects can be pasted.
A protective cover is added on the surface to prevent water from penetrating the light strips, even in bad weather or even underwater. It can be normal use.
For the light strips of the waterproof series, please refer to Yiford website.
Waterproof COB light strip into water.
This wave is wonderful. Throw the COB light strip into the water. It can still work normally, with even light and waterproof grade of IP67. outdoor lighting, Don't worry about being hit by rain on your light strip.
DIY cob led strips to fish tank
What can the led lights of the fish tank do?
Why choose low-voltage light strips？
Therefore, the heat dissipation speed of the chip of the COB light strip is faster than that of the lamp bead type, and the light decay of the COB light strip is smaller and the life is longer.
Earlier we saw the structure of the COB led strips. Its chip is directly connected to the PCB. The chip emits light directly from the bottom without any obstructions, so the light-emitting angle can reach 180 degrees. The SMD led strips have a bracket, and its light-emitting angle can only reach 120 degrees under the influence of this bracket. The COB led strip with a light-emitting angle of 180 degrees can illuminate a wider range.
As a new type of luminous product, the COB light strips have more functional enhancements due to technological innovation. Its features are far more than what I have introduced in this video. I believe you can discover more COB light strips when you use them. Use its characteristics to create more meaningful products or more interesting lighting projects.
