What do you mean you are 'guessing' about the output measurements? –AngeloQ Mar 18 at 16:12 well, if i connect this driver to a chinese 50w led COB that rev 2017.8.14.26784 Electrical Engineering Stack Exchange works best with JavaScript enabled Affiliate Save big on our App!

As with the BuckPuck driver, the maximum number of LEDs you can power with a single driver in-series is determined by dividing the maximum output voltage of the driver by the In this thread I was attempting to simplify the equation, and I believe I succeeded. Further that this company also matches to: Bridgelux-Compatible LED Drivers CREE-Compatible LED Drivers GE-Compatible LED Drivers XICATO-Compatible LED Drivers SAMSUNG-Compatible LED Drivers Note that driver specs are given corresponding to specific When the same COB is run at the maximum allowable current of 3,600mA, voltage is up above 37.5V.

What Is A Led Driver

See how an AC driver will benefit you! We also have this Driver Selector tool that helps calculate what driver would be best by inputting your circuit specs. Also, I received a bit of info that helps explain LEDs, it comes from a fella who's name is Don Klipstein. Forward Voltage In the interest of keeping things simple, I recommend wiring your COBs in series (unless you have a whole whack of them running off of a small number of

  • The drivers are labeled as 500-550mA and 50-100V.
  • Reply LEDGardener (Post author) February 22, 2017 at 7:56 pm Hi Crystal, Since Mean Well underrates some specs on their drivers, you will be fine if you're a few volts under.
  • The reverse is true for lower colour temperatures.
  • So for our above example we would want at least 21.6 watts (18 x 1.2 = 21.6).

The usual LED drivers are switchmode type current regulators. For example, viewing the graph below, you can see that when you run a 36V CXB3590 at 1,400 milliamps (a common drive current), voltage will not be 36V, but somewhere between 34V and Quote 3 members found this post helpful. Led Driver Constant Current Higher drive currents will result in more light from the LED, and will also require more wattage to run the light.

Let's say you opt for the more common version which has a typical forward voltage of 36V.

If this works out I hope to get about 210-220 total watts of COB LED light out of the fixture, figuring in energy needed for cooling the fixture it should still

A caveat to the typical forward voltage is that at different levels of current and heat, voltage will change slightly. Constant Voltage Led Driver I do want ample protection for longevity of the system so I was thinking to use resistors at each LED for a second line of protection even if I used a Some golden info in this thread.

Only a couple of our strips take 24VDC in and those tend to be higher powered LED strips, is there a reason you need 24VDC input? Order) Zhongshan Mao Shuo Electronics Technology Co., Ltd. Forward Voltage is the amount of volts the light emitting diode requires to conduct electricity and light up. Led Power Calculator Regarding COB type lighting I'm little foggy on matching chips to drivers, I'm trying to learn.

You are driving the supply 20% over its rated capacity. You can do this by using this formula: [Vf x Current (in Amps)] x LEDn = Wattage So if we are trying to power the same 6 Cree XPG2 LEDs at If your driver has a power rating (watts), then multiply the driver's current rating by the LED's voltage rating to get your LED watts. asked 4 months ago viewed 121 times active 4 months ago Related 0High power led driver for COB leds-1Cumulative LEDs2Do COB LEDs usually need electrically insulating from the heatsink?1How to properly

For instance, the driver above has a minimum output of 15 volts. Lower values (e.g.- 2700K) are warmer and higher values (e.g.-5000K) are cooler. Since the minimum output voltage is greater than that of our single XPG2 LED (2.9V), you would need to connect at least 6 of these together in-series to work with this Add to Compare Response Rate: 74.2% Transaction Level: Contact Supplier Tags: Led Cob Light Driver | Meanwell 150w | Lpv-150 | View larger image LPV-150 Meanwell 150W led COB light driver

With any luck, this has shed some light on how to go about selecting and matching different LEDs and drivers - at least at a basic level. There are 4 different sizes in the Vero series: Vero 10, Vero 13, Vero 18, and Vero 29; the number reflects the size of the Light Emitting Surface. So if you were in Boost-Only mode you could power up to 16 LEDs (48/2.9). LED supplies 3,190,799 views 9:39 What's inside a Tesco Power Hit disposable phone charger. - Duration: 6:00.
