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. Things to consider before selecting an LED driver
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.
What’s the difference between a flashing yellow and red traffic light?
Flashing beacons. In the United States, a flashing red light is the equivalent of a stop sign. In the United States and Australia, flashing yellow does not require traffic to stop, but drivers should exercise caution since opposing traffic may enter the intersection after stopping.
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.
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.
How to stay safe when driving at night?
Following another vehicle at night. Here are a few additional car headlight tips to help you stay safe and avoid a collision when driving at night or in adverse weather conditions: If an approaching vehicle is using high beams, keep your eyes to the right edge of your lane. Reduce your speed .
When to turn on your headlamps when driving at night?
At the very least, you should turn your headlamps on about an hour before dusk. This makes it easier for you to see as the sun sets, but also makes you more visible to other drivers. Of course, during times of bad weather, consider using your lights regardless of the time of day.
Why do my rear lights stay on all time?
sounds to my like there is a bad connection from (-) to the chassis somewhere. In this case the (+) from somewhere else is using the (-) connection of your rear lites and that’s the reason why the stay on all time. If you know how to use a multimeter follow the wires backwards an see where the (+) comes from.
