Introduction to Types of LED
The following article provides an outline for Types of LED. In the past, people had limited usage of LED, and it was only available in a few designs. However, advancements in technology have greatly developed LED, and now it is implemented in various styles such as golf balls, tubes, reflectors, GLS, and spotlights. It has different powers equal to incandescent bulbs and has various fittings like bayonets and screws.
The cost is reasonable when compared to other bulbs. So it provides a considerable cost-cutting in electricity bills. LED stands for “light-emitting diode,” which is a semiconductor component that emits light energy through the phenomenon of electroluminescence. It comprises of PN junction that ejects light in a forward biased. It applies in all fields like automobiles, street lights, offices, home lighting, smartphones, and televisions.
List of 9 Different Types of LED
The wide implementation of LED has advanced features like small size, robustness, durability, long-lasting, consumption of minimum power, and instant switching. Because of these reliable features, the LED gained more attention from many people. Students, engineers, and electronic enthusiasts love 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 compared to the 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: cool white LED, warm white LED, and daylight LED. Most homes use halogen bulbs, which are warm white. The daylight LED color, characterized by stark white with a hint of blue, finds its primary use in highlighting the true colors.
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 offers a series of LED miniatures along the tube length and is accessible in all sizes, which fits as expected.
4. SMD LED
It is expanded as a surface-mounted device and is popular in LED lighting. The SMD chips mounted in the bulb have additional brightness, which is reliable in offices and households.
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 ratio to the lumen, which signifies high productivity.
6. Graphene LED
The popular channel BBC charged the evolution of light comprising LED filament shaped lined with graphene and marked it as the most available one in late 2015. It is cheaper than standard bulbs and claims to decrease energy bills by around 10%. The usage of graphene was invented by a Russian scientist operating at Manchester University. The battle is live and helps find the innovative use of durable materials.
7. Traditional and Inorganic LEDs
The LED is available in a traditional method with an embedded diode and manufacturers produce it using inorganic components. Manufacturers produce the most widely applicable LEDs using compounded semiconductors like gallium arsenide phosphide, aluminum gallium arsenide, and other materials. The color of LED light is based on the used materials.
These LEDs personify as small LEDs, indicating panels with different LED formats and types. They can be classified as inorganic LEDs, encompassing various styles such as surface-mounted LEDs, flashing LEDs, multicolor and bi-color LEDs. These LEDs can operate with variable voltages and include single color LEDs in 5mm size, as well as alphanumeric LED displays. Wide quantities of these inorganic LEDs are implied.
8. Maximum Brightness LEDs
High-intensity LEDs and High brightness LEDs came under the inorganic LED and started their implementations in lighting and decorating applications. Such type of LED is now becoming a mandate 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. Mounting the LED on a heat sink effectively eliminates the unwanted heat emitted by the LED.
The LED is a considerable replacement for many traditional lightings when discussing efficiency. The widespread use of automated lamps for domestic lighting is now prevalent. It has great advantages in environmental factors and efficiency over CFLs, compact fluorescent bulbs, and incandescent tube lights. The efficient level of HBLEDs is maximum and has a long life when switched off and on multiple times. But the lifetime of such bulbs is finite when it is overlooked.
9. Organic LED
Organic LED (OLED) technology is based on the fundamental concept of light-emitting diodes. OLEDs get their name from their construction utilizing organic components. The primary 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 manufacturers produce the organic LED display in thin sheets, and it produces a diffused light area.
Primary elements of the LED include a thin film material printed on a glass substrate and a circuit comprising semiconductor components. These components transmit electrical charges to the embedded pixels, resulting in the glowing of the LED. LED technology keeps increasing along with its efficiency level and has no boundaries to be implied in any field.
The brightness of the bulb relies on its wattage, and it can be directly compared to the brightness of incandescent bulbs. However, LED bulbs have a significantly lower power consumption while producing the same amount of light energy, making them highly preferred and adaptable in various industries. In today’s competitive electronics world, LED bulbs come in a wide range of designs and colors, making them sustainable and versatile.
