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.
Do you need a constant current LED driver?
Constant-voltage drivers power LEDs that require a fixed output voltage with a maximum output current. In these LEDs, the current is already regulated, either by simple resistors or an internal constant-current driver, within the LED module. These LEDs require one stable voltage, usually 12V DC or 24V DC.
What are the different types of LED drivers?
There are two main types of drivers, those that use low voltage DC input power (generally 5-36VDC) and those that use high voltage AC input power (generally 90-277VAC). LED drivers that use high-voltage AC power are called Off-Line drivers, or AC LED drivers. In most applications using a low voltage DC input LED driver is recommended.
Why is it important to know about LED drivers?
An LED driver is an electrical device that regulates power to an LED or a string of LEDs. It is a crucial piece to an LED circuit and to operate without one will result in system failure. Using one is very important in preventing damage to your LEDs as the forward voltage (V f) of a high-power LED changes with temperature.
Why do we need a constant current LED driver?
The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED (s). This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED. What type of LEDs are being used and how many?
How is the output voltage of a luxdrive driver determined?
When using LuxDrive drivers, you determine the maximum output voltage by subtracting 2 volts from your input voltage. This is needed because the drivers need a 2 volt overhead to power the internal circuitry.
