12 Volt LEDs

LED means Light Emitting Diode. In the phrase Light Emitting Diode, if the term diode is explained you will be clear as to what an LED is. A diode is the simplest form of semiconductor device. To make a semi conductor one has to add impurities of another material in to the pure material. So now the semi conductor consists of pure and impure material. In a diode, the material formation is aluminum, gallium and arsenide. When a semi conductor diode is energized with electricity, the light is produced. LEDs are manufactured in different input voltages. Let's know about 12 Volt LEDs.

You must simply connect a resistor in series with the LED or LEDs to use LEDs for 12 Volt applications. The resistor will drop the extra voltage and limit the current. Use a 0. 125 watt or larger resistor to the anode of the LED and connect the +12 Volt to the resistor. 12 volt LEDs used in automobile industry also. The LEDs are connected in series to have the required light intensity. The 12 Volt Dc current is being used from the battery of the vehicle. The same 12 Volt current is used in the 12 Volt LED light system of the vehicle. As earlier explained, the resistors are connected serially to stop excess current and voltage. At the time of running the engine, the intensity of the light will be little increased due to the 13v - 14v charging current from the dynamo / alternator. The value of the current resistor must be lowered; depending on how many LEDs are in series. You can connect up to 4 red, orange, or yellow LEDs in series with each other and one resistor to power with 12 volts. A maximum of 3 of the other colors can be in series across 12 volts, because of their higher forward voltage requirement.

An LED capsule is a 5mm LED encased within a hard plastic shell. Resistor required for operation is integrated out of site, within the shell. Cases are available in 64 custom colors. Several common applications may include automotive lighting, robotics, home interior lighting, aeronautics lighting, and marine lighting; showcase lighting with the white LED, sign illumination, science projects, special effects, photography with the white LED and many more. Our capsules make 12 volt LED applications easy. Nowadays solar systems are also famous and promoted field. Solar energy is converted in to electricity and stored in battery. The solar energy also can be directly used. The 12 Volt batteries will be connected with solar panel for charging the battery. The same time a parallel connection can be used directly also. The charged 12 Volt battery is connected to the 12 Volt LED light system and the required light is produced. The 12 Volt power supply is most commonly used in the different type of equipments. The same reason 12 Volt LEDs are also common. This is the reason the 12 Volt LEDs are more in the market also.
