Introduction to Types of LED
The following article provides an outline for Types of LED. In the olden days, the usage of LED is limited and is available only with few designs. But nowadays, technology is developed to a greater extent and LED is implemented with different styles like golf balls, tubes, reflectors, GLS and spotlights. It has different powers equal to incandescent bulbs and has different fittings like bayonet and screw.
The cost is reasonable when compared to other bulbs. So it provides a considerable cost-cutting in electricity bills. LED is expanded as a light-emitting diode is a semiconductor component that ejects light energy because of the electroluminescence effect. It comprises of PN junction that ejects light in a forward biased. It is applicable in all fields like automobiles, street lights, office, and home lighting, smartphone, and televisions.
List of 9 Different Types of LED
The wide implementation of LED has advanced features like small size, robust, durable, long-lasting, consumption of minimum power, and has instant switching. Because of these reliable features, the LED gained more attention in a huge set of people. Students, engineers, electronic enthusiast loves to work with LED in their projects.
1. Dimmer Switches
The LED is available with dimmer switches similar to other bulbs. The dimmer switch in normal incandescent bulbs doesn’t work well when compared to dimmer switch with LED bulbs. So it is advisable to replace standard bulbs with LED bulbs as it operates with minimum wattage than other standard bulbs.
2. Color LED
The color LED attracts every person and is available in three varieties like cool white LED, warm white LED, daylight LED. Most of the home use halogen bulbs which are warm white. The color in the daylight LED which has stark white and hint blue in it which is mainly used for highlighting the real color.
3. LED Tubes for Lighting
It is implemented to substitute the fluorescent tubes and in a few cases, it can be the single hanging replacement. The other designs require new ballast and rewiring. It operates by offering a series of LED miniatures along the tube length and is accessible in all the size which fits as expected.
4. SMD LED
It is expanded as a surface-mounted device and it is popular in LED lighting. The SMD chips mounted in the bulb have additional brightness which is reliable in office and household.
5. COB LED
The COB stands for chip on board which is another LED generation and offers a strong amount of light than SMD and has an accessible option as the user considered a beam of controlling light. It serves a better watt ration to lumen that signifies as it has high productivity.
6. Graphene LED
The popular channel BBC charged the evolution of light comprises LED filament shaped lined with graphene and marked as the most available one in late 2015. It is cheaper than standard bulbs and claims for the decrement in energy bills around 10%. The usage of graphene was invented by a Russian scientist who was operating at Manchester university. The battle is now live and helps in finding the innovative use of durable materials.
7. Traditional and Inorganic LEDs
It is available in a traditional method with embedded diode and produced from the inorganic components. The most widely applicable LEDs are made of compounded semiconductors like gallium arsenide phosphide, aluminium gallium arsenide and much more. The color of LED light is based on the used materials.
These LEDs are personified as a small LED which is implied in indicating panels with the various format of LED and its types. It can be even categorized in an inorganic LED that has various styles of LED like surface-mounted LEDs, flashing LEDs, multicolor, and bi-color LEDs which can be operated by variable voltages, single color LEDs in 5mm, alphanumeric LED display. Such types of inorganic LEDs are implied in wide quantities.
8. Maximum Brightness LEDs
High-intensity LEDs and High brightness LEDs comes under the inorganic LED and started its implementations in lighting and decorating applications. Such type of LED is now becoming a mandate as same as inorganic LEDs and has output with maximum light energy. To obtain the maximum light as output, the LED needs manageable power dissipation and current levels. The LED can be mounted on the heat sink to eliminate the unwanted heat emitted.
When discussing efficiency, the LED is a considerable replacement for many traditional lightings. The domestic lighting with an automated lamp is now employed widely. It has great advantages in environmental factors and efficiency over the CFLs, compact fluorescent bulbs, and incandescent tube lights. The efficient level of HBLEDs is maximum and has a long life when it switched off and on multiple times. But the lifetime of such bulbs is finite when it is overlooked.
9. Organic LED
The organic LED is deployed with the fundamental idea of light-emitting diodes. As the name implies, the LED is built with organic components. The basic light emitting diode uses the basic inorganic semiconductors with different levels of dopant and emits light from the dedicated PN junctions which are the focus of light. The organic LED display is manufactured in thin sheets and produces a diffused light area.
Mostly it is a thin film material that is printed on the glass substrate. The circuit made in semiconductor components used to transmit the electrical charges to the embedded pixels which make the LED glow. The LED technology keeps on increasing all the time along with its efficiency level and has no boundaries to be implied in any field.
The brightness of the bulb is assessed by its wattage and it is fine like incandescent bulbs. But the LED has an amazing factor of power consumption when compared to usual ones to produce the same quantity of light energy and that’s why LED is preferred and adaptable in all industries. Nowadays, various designs and colors are introduced which makes them sustain in this competing electronics world.
