Power Supply For Led Lights Circuit

The leds in the above discussed led lamp circuit can be also protected and their life increased by adding a zener diode across the supply lines as shown in the following image.

Power supply for led lights circuit.

The zener value shown is 310v 2 watt and is suitable if the led light includes around 93 to 96v leds. 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 subject. Consistent led performance with any power supply and led s costs about 1 only 4 simple parts to connect efficiency can be over 90 with proper led and power supply selection can handle lots of power 20 amps or more no problem. As you ve probably put together from the info in the last section you ll need a battery a resistor and an led.

Led drivers and led power supply units are used across a wide range of indoor and outdoor led luminaires. Running a series circuit helps to provide the same amount of current to each led. Take our n3500 switching power supply for example. The circuit must provide sufficient current to light the led at the required brightness but must limit the current to prevent damaging the led.

We re using a battery as our power source because they re easy to find and they can t supply a dangerous amount of current. In this circuit we will try to connect three 5mm white leds in parallel and light them up using a 12v supply. Simple led light emitting diode circuit diagram. Here s a really simple and inexpensive 1 led driver circuit.

In electronics an led circuit or led driver is an electrical circuit used to power a light emitting diode led. Circuit 3 of simple led circuits leds in parallel the final circuit in the simple led circuits tutorial is leds in parallel. The interesting thing about series parallel led circuits is how easily you can expand the number of lights on a given power source. The basic template for an led circuit is pretty simple just connect your battery resistor and led in series.

The requirements of a lighting application often dictate what type of circuit can be used but if given the choice the most efficient way to run high power leds is using a series circuit with a constant current led driver. The power supplies focus on meeting criteria for efficiency power factor pf total harmonic distortion thd emission thermal management and specific standards such as ul en and iec. The circuit diagram for leds in parallel connection is shown in the following image. Power led s simplest light with constant current circuit.
