Understanding LED Drivers Light Bulbs from the Web's #1
Understanding LED Drivers A Original Document . 1 What Is An LED Driver? cause a change in the current being supplied to the LEDs. LED light output is proportional to its There are two main types of external LED drivers, constant current and constant voltage,
DC Input Constant Current LED Drivers
DC Input or Low Voltage LED drivers take DC voltage from a battery or switching power supply and output a constant current so as to keep the LED safe. This way, when the LED's electrical characteristics change due to heat, the LED will stay at a safe driving current, while the voltage can vary depending on the LEDs needs.
LED Drivers: Constant Current vs. Constant Voltage
Constant current and Constant voltage drivers are both viable options for a power supply for LED light sources, what differs is the way in which they deliver the power. LED drivers are the driving force that provides and regulates the necessary power to make sure the LEDs operate in a

Controlling LED lighting systems: introducing the LED
"An LED driver is the power supply for an LED system, much like a ballast is to a fluorescent or HID lighting system," says Al Marble, manager sales & market development for Philips Advance Transformer. LED drivers may be constant voltage types (usually 10V, 12V and 24V) or constant current types (350mA, 700mA and 1A).
LED driving and controlling methods
So i will place this chip against some other LED drivers to see how good it is. The chip that I'm talking about is the A6210 from Allegro Microsystems. It is a Buck Regulating LED Driver able to drive up to 3A load with constant current, with switching frequencies up to 2 MHz and supply voltage from 9 to 46 volts.

How to dim an LED with constant current supply
The name "constant current" is kind of misleading, I prefer "current limited". You can let the LED pull on the supply as hard as it wants, but it will only ever get 300 mA. If you shut off the LED the supply won't push harder than its rated voltage to force 300 mA through it. With the supply you linked that is 13 V, so it would just output 13 V

P467 04/09Driving LEDs1. IntroductionPrior to driving an LED, which is a kind of semiconductorproduct, it is necessary to thoroughly comprehend itsproperties. For instance, fluctuation of the forward voltage Vfon an LED causes steep variations in the forward current If. Inthe case of Fig. 1, if the temperature conditions are constant,a 10% rise in Vf results in an increase of If by more
Driving LED lamps some simple design guidelines LEDs
Driving LED light sources LEDs are semiconductors with light emitting junctions designed to use low voltage, constant current DC power to produce light. LEDs have polarity and, therefore, current only flows in one direction. Driving LEDs is relatively simple and, unlike fluorescent or discharge lamps, they do not require an ignition voltage to
