Features & Benefits of COB LED Strip

Unitop manufactures top-quality COB LED strips with various unique features & benefits. Below you will find details.

What is COB LED Strip?

The new Unitop flexible COB LED Strips are strikingly consistent in color and brightness. Their unique COB technology enables hundreds of LED chips to be encapsulated in the tiniest flexible circuit board. Combined with a phosphor layer on the LED Strip, it generates a continuous, uniformly bright line of light along the entire length. There are no noticeable light spots compared with typical standard SMD LED strips. In our factory, COB LED strip is also called COB flexible LED Strip or FCOB LED Strip.

COB Strips comparison

Chip on board (COB) is a method of circuit board manufacturing in which the integrated circuits (e.g. microprocessors) are attached (wired, bonded directly) to a printed circuit board, and covered by a blob of epoxy. By eliminating the packaging of individual semiconductor devices, the completed product can be more compact, lighter, and less costly. In some cases, COB construction improves the operation of radio frequency systems by reducing the inductance and capacitance of integrated circuit leads. For more details of this technology, you can check Wikipedia.

what is COB

COB is also a type of LED, so this question does not make any sense. However COB LEDs have many advantages comparing with traditional SMD LEDs, you can continue read our FAQ as below.

There are a lot of advantages of COB LED strips including no lighting spots, better light, more flexible, more efficient, and etc. You can read our article for this.

COB LED technology produces a considerably brighter light than traditional LED technology! They’re even more bright than high-density strips. Flip-chip LEDs, unlike SMD LEDs, are not enclosed in a plastic holder, therefore they produce dazzling, constant light from a broader angle. This enables them to generate light from the strip’s sides, which reaches more than 180 degrees. A wider light angle gives you more light, which is important for long-term brightness.

Yes, they are dimmable.

Our standard COB LED strip light is IP20, we also have IP65, IP66, IP67 for choice. See below:

1. Clean the area where the COB led strip light will be installed.
2. Measure the length of COB led strip light you want to install and cut it to size.
3. Tear the COB led strip light’s 3M backing.
4. Apply the COB strip light to the desired location.
5. Connect the COB led strip light to the power supply.
6. You can solder or utilize the connector to connect the COB led strip light.

It is our goal to provide our customers best quality products. To ensure our COB LED tapes are with highest quality, we have put them all in strict tests in our own factory labs and also the Safety Agencies. All our COB LED strips are with CE, RoHS certificates. Many of our customers also used our products to get certificates in their own countries.
