Several Types of LEDs

Light emitting diodes, or LEDs, are electronic lights. They are produced in a variety of shapes and sizes. There are several types of LED lights, which can be found in any number of electronic devices and have various functions.

The first is Miniature LEDs. They are some of the most common types of LED lights and can be found in small electronic devices. Miniature LEDs are used in an array of devices with surface-mount or through-hole designs and mostly used as indicator lights on devices such as calculators or cell phones.

 It is possible to use a miniature LED light without package, such as a cube or dome. Lights not packaged are simple semiconductor chips connected to conductive wires. Miniature LED lights are divided into three categories: ultra-high output, standard and low current.

The second is High-Power LEDs(HPLEDs). They are produced a much stronger light source than most other LEDs and becoming more popular for house decorating and lighting.Their initial cost is relatively high but due to a long lifespan, they typically save on energy costs in the long term. So they are good replacements for fluorescent and incandescent lights as they are proving to be more energy saving. HPLEDs are known as solid state lights. Their electroluminescence is generated through a small, solid mass, rather than through more sensitive and brittle bulbs or fluorescent tubes. The danger of an HPLED overheating is high and must, therefore, be mounted on heat-absorbent material, allowing the light to cool through convection. Too much heat can cause an HPLED to burn out quickly.

The third is Super Flux LEDs. They can be found most commonly in large panels like billboard advertising. Large video screens are often made from LEDs. Large Panels types of LEDs are designed for maximum light emission, as they consist of two positive and two negative leads.

The forth is Flashing LEDs. They are stand-alone lights that serve as indicators. To make a LED flash or blink, a vibrator is integrated into the circuit that interrupts its flow in intervals.

The fifth is Bi-color LEDs. It combines two light emitting dies connected to one lead in one encasing, allowing for the case to emit two different colors. The current flow of the dies alternates to produce the color variation. Bi-color LEDs can also produce a third light when the flow of both dies is equal.

The last is RGB and Tri-color LEDs. RGB LEDs are the red, green and blue light emitting diodes, commonly found in LED televisions and projections. The LEDs are emitted through a four-wire connection on a common lead.  Tri-color LEDs combines two light emitting dies in one encasing. In contrast to the bi-color LEDs, the tri-color dies are connected to two leads. This enables the two LEDs to light up simultaneously and be controlled. The third lead shares one of the common leads.
