To understand the LED characteristics, you must understand how the diode works, because the LED is a variant of the diode components. In this paper, I will not explain the diode characteristics in detail as well as in Physics subjects as well as Basic Electronics courses best led headlights and conversion kits. Diodes are usually used to rectify alternating current (AC: alternating current) into direct current (DC: direct current).LED will turn on when there is currently flowing through it, meaning LED can also be used in AC voltage, it’s just also blinking and because our eyes can not see it then visible light up, because AC voltage we use is 50 Hz (Hertz, times of life and death within 1 second). Well, in reality, LEDs cannot be directly used like incandescent lamps that can be directly used using 220 Volts AC voltage which is usually generated by PLN and flowed to all home and office. It also differs each country, in our country the magnitude is 220 Volts. When you need LED lights, you can come to us to get the best led headlights.
As with any other electronic equipment, to use the LED the voltage must be lowered first and better converted to DC voltage. To my knowledge, no LEDs use voltages up to 220 V, although there are also High Power LEDs that use voltages up to 40 V. There are many ways of lowering and converting AC voltage into DC, that is Power Supply (we usually know by the name of adapter). Power Supply usually uses a transformer (transformer) and electronics rectifier circuit, but some do not use a transformer (Transformerless Power Supply), as well as switching power supply mobile phone (using IC Power), and some use only parallel circuit between resistor and capacitor then directly connected another electronic circuit like LED. But in terms of electronics is not recommended to use directly from the power grid (electricity from PLN) with the electronic circuit that we use, especially if it will be used for a long time every day; because there is a risk of fire and someone can be stung by a large electric current. Switching Power Supply is still feasible to use if the components used are also good quality, but not the case with a parallel resistor and capacitor circuit.
