What are the different types of LED resistors?

There are many types of LED resistors and are categorized according to the color of their light or the number of light colors they produce. Many people think that the color of the plastic cover on the LED resistor determines the type of LED light, but the color is actually the result of the wavelength of the light emitted when the semiconductor metal is electrically excited. Most LEDs produce only one color of light, but some types offer two colors-color-free-or three colors-color-in one LED package and can turn on one or more colors at the same time. Many LED types are used in light situations that benefit from low performance, long life or bright light from very small bulbs. Blue and white LED resistors are a relatively newer LED type and are usually more expensive. Different types of LED resistors have different types of metals inside. For example, aluminum arsenide Gallium - aluminum, gallia and arsenic compound - red in red LEDs, while Gallium arsenide phosphide - Gallia, arsenic and phosphorus - oran compoundŽová to produce orange ice. Zinc selenide, zinc and selenium compound are used in blue LED resistors.

Some of the advantages of LED bulbs are their low energy requirements, long life and bright light. Low LED performance requirements make LEDs ideal for use in controlled batteries that produce bright light, including LED displays in mobile phones, presentation indicators, keyboards, LED lights and LED headlights. The LED lamps can work longer without replacing the battery with significantly smaller, lighter batteries such as two AA batteries, instead of traditional bulbs require two or more heavy d size batteries.

In addition to low energy requirements, a long lifetime causes LED lights to be ideal for lighting, where the replacement of bulbs would be more expensive or leading to safety problems. Therefore, a large amount of LED resistor isThey often accumulated to provide light in traffic signals, signposts of cars and air lighting. Since there would also be an advantage of low energy requirements in the household, LED room lighting can become popular, as technology improves and prices are falling.

All types of LED resistors are diodes emitting light that shines when the current flows forward. In the correct orientation, the LED circuit to the LED resistor must be connected. The anode, the longer of the two wires that move to the LED packaging, must be connected to the positive side of the battery or power. The shorter the two wires to the ice, the cathode, must be connected to the negative side of the battery non -clinging. Another way to identify the cathode is that one side will usually be slightly flattened on round ice; That's cathode.
