What is a COB LED?

Relatively new to the LED market, chip on board (COB) LEDs offer many advantages over the standard options. COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module.

Is COB LED better than LED?

Simply put, COB LEDs are brighter, consume less power, and output a higher quality beam of light compared to older LED technologies found in most other trade show lighting today. The next time you are in the market for exhibit lighting, insist on COB LED technology!

What is the difference between COB and LED?

The SMD LED light source is a single patch LED lamp bead with a light-emitting diode directly attached to the surface. COB LED light source packaging technology is a direct chip package on the board, COB has improved light efficiency, improved glare effect of LED lights, and reduced light loss.

How long does a COB LED last?

A COB LED has an average rated lifetime of 50,000 hours. That is assuming a person uses them for 12 hours a day on average.

Are COB LED good?

While COB LEDS do provide an excellent light intensity, they’re not exactly the best when it comes to spread, because COB LEDs are a single-point light source (meaning all light comes from a single point in space).

Do COB LED get hot?

COB LEDs are high-power components that therefore generate high temperatures. For example, the XHP70. 2 LED designed by Cree can utilize up to 28.8 Watts of electricity at 6V, which creates a significant amount of light and plenty of unwanted heat.

Are COB LED lights dimmable?

It is dimmable means that you can select any brightness level you like. (Take your attention: This COB led rope light is for DIY, Power supply and controller are not included).

What is a COB LED grow light?

What Is A COB Grow Light? COB stands for Chip-on-Board and refers to the way LED diodes are packed together. With chip-on-board technology, many tiny LEDs are mounted in close proximity on a substrate to form one single module. In essence, they are combined to form a single, extremely powerful, light source.

Do COB LED need heatsink?

In the case of COB LEDs, it is possible to directly attach a COB LED to a heat sink (see Figure 2). As a result, COB LEDs do not require PCBs in order to install LEDs into a luminaire and the subsequent reflow process is no longer necessary.

Do COB LEDs need drivers?

LED Drivers

LED drivers are the handy little boxes that take the power from your electrical outlet and convert it to a form that the COBs can use. The electricity coming from your outlet is alternating current (AC), and this does not work for COB LEDs – they require direct current (DC) instead.

How efficient are COB lights?

COB construction allows a single driver to power multiple chips. The result is more light output per square inch. COB LEDs also produce less heat. COB LEDs have proven very effective in flood lights and light bulbs where SMD LEDs would not fit into a small space at higher power levels.
