How To Design a Simple LED Circuit

You are looking for something that can light up a room without the unwanted expenditures entering the fray. In a situation like this you might want to call on the services of a light source with low current requirements. Moreover, it possesses the necessary durability that will carry you throughout your lighting project. Welcome to the world of LEDs. 

Here's how you can set up a simple LED circuit design.

  1. Meet with Mr. Voltage. Your initial steps should be founded on determining the amount of safe voltage that can be utilized. This can be achieved by identifying the type of LEDs. Types are usually equated with color brightness. You should also talk numbers as the amount of LEDs can affect the appropriate voltage requirement.
  2. More on numbers. Establish a good connection between the power supply and the voltage. There should be smooth communication between this pair to produce a good showing. The ideal detail that can be of help is the specified information of the manufacturer regarding diode forward voltage. It is commonly seen on regular LED packages or you can go through the site of the manufacturer.
  3. Avoid a struggle for power. Lay out all the needed details and choose wisely between two power sources. You can either attach yourself to a steady outlet or you can enjoy the mobile benefits of batteries. If you like things to be simple and easy to handle then the latter will suit you better. There are tons of battery variations on store shelves that can provide your power needs. You can harness the power of AC by going through your wall plugs. Cut the plug off the cord then get the polarity affairs in order using a multimeter. In an AC setting, voltage travels in waves so the LED can only be driven half of the time. The presence of the wall plug in your design will facilitate for full power distribution as it can act as a full-wave bridge rectifier. Do not forget to come up with a power supply that is greater than the diode forward voltage.
  4. Calm the current. Your LED set-up will not be able to handle the amount of current without the help of a resistor. The resistor will act as your control unit that will manage the amount of current passing through your design. Calculating the resistor value is of utmost significance. You can do this by getting the difference between the LED voltage and supply voltage. Once you get the figure, divide it by the LED current.  You can utilize the nearest resistor value if the obtained figure is not available but make sure to get one that is higher. Doing so will reduce the current thereby contributing to the patency of your power supply.
  5. End nicely. Your project will have a longer time to shine if you make efforts in organizing the wiring. There are tons of PCB (printed circuit board) variations in the market that can hold your design together. Have more colors flying by mounting your creation on one of those plastic LED holders.

With the right knowledge and technique cooking up a simple LED circuit can be both satisfying and enjoying. Take pride as you watch your design turn heads with each flicker.
