What is a dimming driver?
Dimmable drivers offer superior dimming and control to inexpensive PWM dimmers that install on the low voltage (12V or 24V DC) side of the circuit. They’re a permanent and elegant solution that keep wires hidden away inside your walls, and dimming control where you expect it – right at the switch.
Can all LED drivers be dimmed?
Both constant-current and constant-voltage LEDs and drivers can be made with a dimming capability, though both LEDs and drivers must specify that they are dimmable on the product datasheet for that assertion to be made. If the specs don’t mention dimming at all, it is safe to assume that the product is not dimmable.
Does dimming LED extend life?
Since dimming, either by reducing current or by pulse width modulation, results in lower overall junction temperatures, it will have no negative impact on LED life; it might even extend life.
Why do we need dimming curves?
In LED drivers this is called dimming curves. To achieve perceived linear dimming, the brightness of the LED must be matched to the way our eyes behave. With a linear dimmer, a logarithmic dimming curve should be used in the driver. And with a logarithmic dimmer, a driver with a linear dimming curve should be used.
What are the different types of dimming for LED drivers?
Switched Mains (Non Dimming) If you don’t need to dim your LED fitting then this is the driver type to choose.
What makes a led “dimmable”?
When surge wattage occurs, the power drain can make the LED lights dim or flicker. A solution to this is to put all appliances on separate breakers as this will lessen the surge wattage. The dimming or flickering of LED lights will probably occur no matter what.
Do you use led dimmable driver for lighting?
Dimmable power supplies, also called LED drivers, are a great option when you are replacing existing incandescent or fluorescent under-cabinet lighting or when you have an electrical outlet controlled by a wall switch. Simply wire the dimmable driver to the existing outlet wiring, and replace the on/off AC switch with an AC dimmer.
Why do we use driver in LED lights?
The real answer here is that LEDs use a driver, which does many of the same things as a ballast but operates much more effectively. An LED driver is an electrical device which regulates the power to an LED light. It has the capacity to regulate power to a single LED Light or strings of LEDs.
