Are COB lights 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 does COB mean in LED lights?
Chip on Board
COB, or Chip on Board is a fairly new member of the LED family. Multi LED chips are packed closley together as one lighting module. And when it light up, it appears like more of a lighting panel than multiple individual lights if that makes sense.
How long do COB LEDs last?
High quality LEDs have hands down the highest usable lifespan of any grow light technology available. Even if the initial investment is higher, a quality LED fixture will last AT LEAST 30,000 hours.
Do COB LEDs need resistors?
Therefore, constant current LED drivers are the preferred method of driving LEDs – they operate at a single current and adjust their output voltage correspondingly, ensuring that the forward current remains stable. When constant current input is used, a current limiting resistor is not necessary.
What is the difference between LED and cob?
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. With COB packaging technology, labor and manufacturing costs are 5% less than SMD. And life expectancy is much higher than traditional SMD.
What is the difference between LED and COB LED?
But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB chips typically have 9 or more diodes. COB chips also only have 1 circuit and 2 contacts, regardless of the number of the diodes. COB is known for better lumen-per-watt ratios and heat efficiency.
Are COB LEDs reliable?
Because the LED chips are directly mounted on the substrate, spot welding is unnecessary, which means, the failure rate of the light is reduced. In general, the design make it durable. Composed of mounted LED chips, cob led array appears as a single light source. It offers high intensity and homogeneous luminosity.
Why is there a resistor before an LED?
An LED (Light Emitting Diode) emits light when an electric current passes through it. The ballast resistor is used to limit the current through the LED and to prevent excess current that can burn out the LED. If the voltage source is equal to the voltage drop of the LED, no resistor is required.
Which is better COB LED or SMD LED?
Although a COB LED is efficient, an SMD LED has an even greater level of efficiency. That’s because more lumens are produced per watt. In other words, you’ll receive more light with less wattage. An SMD LED also produces a broader light beam, which means the light doesn’t need as large of a heat sink as a COB LED does.
How long does a 6W COB LED last?
In fact, our 6W COB LED Trade Show Light will run 14-15 hours using our very small and light weight (1.25lbs) rechargeable Mobile Power Center. High quality light output over extended periods of time using a relatively small battery was simply not possible just a few short years ago!
What kind of battery does a COB Light use?
As a result, a relatively small and lightweight lithium-ion battery pack can power a COB LED based light system for very long periods of time. In fact, our 6W COB LED Trade Show Light will run 14-15 hours using our very small and light weight (1.25lbs) rechargeable Mobile Power Center.
What are ” cob ” LEDs and why do they matter?
In summary, chip-on-board LEDs are the latest and most advanced technology on the market today. 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.
Which is better led or cob grow lights?
While a few years ago HPS lights were all the rage, growers are increasingly moving to LED grow lights – and even in LED grow lights there have been a number of changes in trends. Some people are quickly moving to fanless quantum boards from old-school LEDs while there are some who vouch for COB lights benign way better than SMD LEDs.
