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 SMD?

SMD is the abbreviation of Surface Mounted Devices, which means: Surface Mounted Devices, which is one of the SMT (Surface Mount Technology) components. Surface mount devices have become the current mainstream electronic assembly technology due to their small size, light weight and high power.

Surface mount device packaging is to attach electronic components directly to the substrate, that is, to package and place the chip components on the printed circuit board, and use a reflow furnace to melt the solder alloy interconnected by the electronic system, thereby realizing the interconnection between the chip components and the substrate. Main technique

SMD's features

High assembly density, small size and light weight of electronic products. The volume and weight of SMD components are only about 1/10 of those of traditional plug-in components. Generally, after SMT is used, the volume of electronic products is reduced by 40%~60%, and the weight is reduced by 60%~ 80%.

High reliability and strong anti-vibration ability. Solder joint defect rate is low.

Good high frequency characteristics. Electromagnetic and radio frequency interference is reduced.

Easy to automate and improve production efficiency. Reduce costs by 30% to 50%. Save material, energy, equipment, manpower, time, etc.

what is led strips?

LED is short for Light Emitting Diode. The light strip refers to the special processing technology of the LED light welded on the copper wire or the strip flexible circuit board, and then connected to the power supply to emit light.

led strips features

1. Soft and can be curled like a wire;
2. Can be cut and extended;
3. The light bulb and circuit are completely covered in flexible plastic, which has good insulation and waterproof performance and is safe to use;
4. Strong weather resistance;
5, not easy to break, long service life,

Compare to COB LED Strips and SMD LED Strips

1. PCB
2. phosphor encapsulation
3. chip
4. gold wire

1. PCB
2. solder point
3. bracket
4. chip
5. gold wire
6. phosphor encapsulation

We can see that the chip is directly connected to the PCB board. The chip on SMD is connected to the PCB board through the bracket and the solder point. SMD’s frame of the bracket has a certain thickness, while the COB light strip does not have this bracket.
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.

What are the features of COB soft led light strip?

Feature 1: Uniform light

Feature 2: High Color Rendering Index

rich color reproduction

It can make the color reproduction better, the object looks richer in color, and the details are more obvious. If you have higher requirements for the color reduction, and hope that the light can better restore the color of the object itself, let the object looks more realistic and more eye-catching, then you must use Yiford high CRI COB led strips, Because compared to the SMD led strips with a color rendering index of about 80, the COB led strips have a high color rendering index of over 90.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.Recommend read: What is Color Rendering Index and Why Choose it Important | Understanding CRI: why-choose-high-color-redering-index-what-is-cri

Feature 3: Good flexibility

strong torsion, good ductility, good effect.This kind of COB light strip is very flexible. Just like this, it is tied into a knot and pulled into a smaller knot. You see, this COB light strip is still good. 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.

Feature 4: Can be cut

easy cut shorter

Parallel circuit boards, cut as long as you want, which greatly facilitates DIY and small scattered projects, COB light strips are generally packaged in a roll of 5 meters. In actual use, the length of the light strips we need will not be an integer of 5 meters. At this time, the cutting characteristics of COB led strips are very useful. 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.

How to cut/connect/power cob led strip lights

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.

If you need to quickly connect the COB light strip, you must not miss the YIFORD accessory connector.

Feature 5: Ultra-thin

easy to hide

The thickness is only 2mm, only to see the light, no light source, not dazzling and more attractiveYou 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?

Feature 6: Variety of colors

colorful lights for space

There are monochromatic ones, as well as RGB colorful ones, applied to the lighting requirements of various occasions. Colorful colors create a colorful world.

commercial lighting

More than 1,000 lumens per meter, can be decorated and illuminated You may also ask, how is the brightness of such a small light strip? 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.

Feature 9: Energy saving

low energy consume

It can replace traditional light bulbs with 5-20 times the power, saving energy and electricity costs. Compared with ordinary incandescent bulbs or tubes, LED has a life span of more than 30,000 hours, which is more energy-saving and durable！ According to calculations, LED lights can save up to 80% of electricity. However, its lighting is not worse than ordinary electric lights. 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.

Feature 14: Safe to touch

Feature 15: Low heat

Feature 16: Wide emit angle 180 degree

easy spread the heat

The copper plate has its own heat dissipation function, which can quickly dissipate the heat, and the self-heating is low. Ordinary incandescent lamps or fluorescent lamps emit a lot of heat, so you can't touch them after a few seconds of work. Since the COB chip is directly bonded to the PCB board, the heat of the chip can be quickly transferred to the PCB board. 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.
