Will DC LED work on AC?
In most applications, LEDs are driven by a DC power supply, but AC offers several significant advantages. Lynk Labs has developed technology that allows LEDs to be driven directly from an AC supply. LEDs are usually considered to be DC devices, operating from a few volts of direct current.
How is the voltage of a LED driver controlled?
These LED drivers provide a constant DC voltage output, typically in the 12V to 24V range. The LED module is connected parallel, designed to run at a specified voltage. With the aid of a current regulator, the current to the LED is controlled.
How is the maximum number of LEDs I can run determined?
The maximum number of LEDs you can run from a single driver is determined by dividing the maximum output voltage of the driver by the forward voltage of your LED (s). When using LuxDrive drivers, you determine the maximum output voltage by subtracting 2 volts from your input voltage.
What should I look for in a LED driver?
The three specifications you will need to look for is the Voltage Range (V), Max Power (W) and Current (mA). Output Voltage refers to the operable voltage range output of the LED Driver. This may be listed on as max voltage.
What’s the difference between tunable LED drivers and constant LED drivers?
Tunable LED drivers are Constant Current LED drivers that have been finely tuned to provide a precise current to the LED module that is less than what the driver is rated for. This is done as a way to adjust light levels while minimizing heat loss. What Information is Needed to Replace an LED Driver?
