What is LED driver IC?
They are configured as either inductorless (charge pump) or switching regulator-based LED drivers that support driving white LEDs in series, parallel or combination. Topologies include boost regulator, buck regulator, buck/boost, SEPIC topology LED drivers, and more.
How hot should an LED driver get?
All of the data sheets for MEAN WELL LED drivers will stipulate the working temperature range. In the majority cases the working temperature range can be as high as 60 degrees or 70 degrees Celsius.
Why to use a LED driver?
LED drivers are used to direct the right amount of electricity to the lightbulb . In the instance of a change in voltage (power), an LED driver would protect an LED bulb from any electrical current fluctuations. These fluctuations can cause a light bulb to vary its light output (brightness), or cause the LED bulb to overheat.
What is a constant current LED driver?
Constant Current LED Driver. The constant current LED driver is designed to deliver a stable constant current to the LEDs, while it reliably varies the output voltage within a certain range according to load resistance. With control chip, this product exhibits good stability, high efficiency, high power factor as well as long service life,…
What is a LED driver or transformer?
DC Versus AC. Many LEDs light up when supplied with power from low voltage transformers.
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.
