What Are COB LEDs?

Chip-on-Board LED or “COB” LED refers to a single module with many LED chips which high density mounted on thermally efficient silicon carbide or sapphire substrate board, and placed below uniform phosphor coating.

What is the benefit of COB LED?

COB LED has the characteristics of good luminous uniformity, high luminous efficiency, good heat dissipation effect, and low production cost etc. using COB LED technology will increase the number of LED light chips many times, and can also greatly reduce the footprint and energy consumption of the LED light array while keep the light output constant.

The important is that it can be design according to the project requirements to meet the application’s shape and size, and design the details of electrical parameters etc. that meet the requirements.

Which is better SMD or COB LED?

SMD and COB LED choose suitable solution based on different application environments.

Relatively speaking, COB light more high efficient due to higher density of light output and the fact that they use fewer components, COB LED module have more uniform luminous effect. while SMD has better effect performance in some special wavebands, such as UV and UVC etc. application.

Is COB LED better than LED? What is the difference between LED and COB LED?

Simply put, COB LED are brighter, consume less power, and output more higher quality beam of light compared to older LED technologies. in COB LED, you’ll have more simpler circuit design which produces compact light.

COB LED is a subdivided category of LED which has more flexible design ideas. regardless from the overall dimension, electrical parameter, light color etc. various aspects, all it can custom design and production as required.

The COB LED issue we can solve

We often encounter some questions from customers:

• What voltage is COB LED?

Usually, we set the working voltage of COB LED to 3V/6V/9V/12V/24V etc according to the requirements, more working voltage can be customize according to your requirements.

• Do COB LEDs need resistors?

Deside whether or not to set resistors based on the design requirements of the project.

• Do COB LEDs need drivers?

Yes, the drivers that meet the working electrical requirements of COB LEDs are required.

• Are COB LEDs dimmable?

Yes, we can design dimmable COB LEDs.

• Is COB LED waterproof?

Yes, COB LED is waterproof.

• What is the maximum length of COB LED?

At present, we can produce max length of 1200mm. for longer and larger products, we will choose seamless splicing way to complete.
