Can you wire LED drivers in parallel?
Now, when you wire in parallel, the forward voltages of each LED no longer add together like they do in series. If your driver outputs 36V, then every single COB that you have hooked up to it in parallel will have that same 36V across it. Instead, the current is what becomes split among the LEDs in a parallel circuit.
Is COB better than 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 is known for better lumen-per-watt ratios and heat efficiency. This has a lot to do with the design of COB LEDs, and the cooling ceramic substrate of the chips.
Are COB lights better than LED?
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.
Are COB LED lights 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).
Are COB brighter 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.
Can you wire cobs in parallel on a constant current driver?
You can also wire COBs in parallel on a constant current driver. When you wire in parallel on a constant current driver, you don’t have to worry about the COBs pulling any more current than the driver is rated for, but the current will not necessarily be evenly split among the COBs.
How are LEDs split in a parallel circuit?
If your driver outputs 36V, then every single COB that you have hooked up to it in parallel will have that same 36V across it. Instead, the current is what becomes split among the LEDs in a parallel circuit. For example, your COB data sheet may tell you that when you apply 36V, each of your COBs will pull about 2,400mA of current.
How many volts are in 3 LED COBs?
If you have 3 LED COBs, each with a forward voltage of 36V at a given current, when you wire them in series, the total voltage drop of the circuit becomes 108 Volts.
What happens when you wire LEDs in series?
When you wire in series, you add the forward voltages of each LED in the circuit but the current fed to each LED remains the same. If you have 3 LED COBs, each with a forward voltage of 36V at a given current, when you wire them in series, the total voltage drop of the circuit becomes 108 Volts.
