How to Make an Electric LED Light |
LED lights require a low-voltage DC supply and each LED must have a resistor connected in series to limit the current. Once these conditions are met, LED lights can provide bright, efficient illumination that lasts up to 50,000 hours. Several LED branches consisting of LEDs and their resistors can be connected in parallel to increase the amount of light generated. LEDs produce very little heat, are resistant to shock and moisture and are more compact than other light sources.
Instructions 1 Cut a circular piece of breadboard 3 inches in diameter. Mount the power LEDs in circles. Place one LED in the center. Space six LEDs evenly around the central LED. Space12 LEDs evenly around the circle of six LEDs. Leave about 1/4 inch of space between the LEDs for heat dissipation.
2 Calculate the resistance of the resistors required. Obtain the LED voltage and the continuous current from the LED specifications. Subtract the LED voltage from 12 volts. Divide the result by the continuous current in amps. The result is the resistance of the resistors in ohms. Typical values would be 3.6 volts for the LED voltage, 300 milliamps equal to 0.3 amps for the continuous current and 28 ohms for the resistor.
3.Calculate the wattage of the resistors. Subtract the LED voltage from 12 volts. Multiply the result by the continuous LED current in amps. The result is the minimum wattage required for the resistor. For a 3.6 volt LED with a continuous current of 0.3 amps the resistor would need 2.52 watts. Choose standard resistors with the next highest resistance and wattage ratings.
4 Solder one end of each resistor to the positive side of each LED. Wire the other end of all the resistors together and connect to the positive side of the power supply. Wire the negative side of all the LEDs together and connect to the negative side of the power supply. The LED light will have an output similar to that of a 60-watt light bulb.
