Cc led driver circuit

Small changes in voltage produce big changes in current, and vice versa. In this video we make a diy high power led driver for a 10 watt led. Future electronics has a broad portfolio of led drivers, including led sink driver, constant current led driver and current regulator led driver. This works well because for many of the colored led stars avaliable, 700 is the limit you can run them at. How to make an led driver circuit hey you about to post something stupid. Constant current cc led drivers keep a constant electric current throughout an electronic circuit by having a variable voltage. I have made an aquarium light and a backlight for my computer monitors. This circuit can drive 9 parallel strings of three white leds in series and can be operated from a 3v dc supply and it. Power leds simplest light with constantcurrent circuit. As a simple project, ive built the driver circuit and connected it to a highpower led and a powerbrick, making a plugin light.

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. If you go with a cv driver, youll need to make sure that you set the voltage output very carefully. It runs 6 of the 3w led stars you can buy for next to nothing. These capacitors are connected line to line and are designed for high voltage ac circuits. Direct ac led driver solution accurate led cc regulation.

Constant current led drivers are designed for a designated range of output voltages and a fixed output current ma. Just make sure your circuit voltage is within your driver s constant current range. Cc led drivers can be used for individual bulbs or a chain of leds in series. Cc drivers are often the most popular choice for led applications. The main component is the xrated ac capacitor, which can reduce the supply current to a suitable amount. Cc drivers are simple because there are no adjustments required. This way, when the leds 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. The circuit is a constant current source, which means that it keeps the led brightness constant no matter what power supply you use or surrounding environmental conditions you subje. The basic principle behind the 230v led driver circuit is transformer less power supply.

Another led driver circuit based on the mp3302 led driver ic. Buy led drivers products online future electronics. Leds that are rated to operate on a constant current driver require a designated supply of current usually specified in milliamps ma or amps a. The guide coolly tells a straightforward 1w, 4w, 6w, 10w, 12w led driver circuit smps which could be build by any new hobbyist for own service.
