Types of LEDs.

In earlier times, the use of LED was restricted, and it was only accessible in a small number of different designs. But technology has progressed to a larger level in recent years, and LED is currently being applied with a variety of diverse forms, such as tubes, reflectors, GLS, and spotlights. It comes with a variety of fittings such as bayonet and screw, and it offers varied powers that are comparable to those of incandescent bulbs.

When compared to other light bulbs, the price is manageable. Therefore, it offers a considerable savings on monthly electricity bills. In its most basic form, a light-emitting diode (LED) is a semiconductor device that emits light energy through the electroluminescence phenomenon. It’s made up of a forward-biassed PN junction that emits light. Every industry may make use of it, from cars to streetlights to office and home illumination to smartphones and TVs.

Types of LEDs:

LED’s cutting-edge properties—including its compact size, sturdiness, durability, longevity, low power consumption, and fast on/off switching, have led to their widespread use. These dependable qualities helped bring the LED to the attention of a large population. LED is a popular component for use in projects by students, engineers, and electrical enthusiasts.

1- Dimmer switches

Like other bulbs, the LED can be used with dimmer switches. Compared to LED bulbs, the dimmer switch on regular incandescent bulbs doesn’t work as well. So, it’s best to replace standard bulbs with LED bulbs, which use less power than standard bulbs.

2- Colour LED

There are three different Colours of LED lights, “cool white, warm white, and daylight”, and all of them are sure to pique anyone’s interest. Halogen lamps, which are a warm white, are often used indoors. The daylight LED is a colour that is meant to emphasise the true colour, and it consists mostly of a stark white with a hint blue.

3-  LED Tubes

LED lighting is used to replace fluorescent tubes, and in a few situations it serves as the only hanging alternative. Rewiring and a new ballast are needed for the alternative designs. It’s available in every standard size and works by providing a string of LED minis down the tube’s length.


It’s widely used in LED lighting and may be attached to any flat surface. The SMD chips installed in the lightbulb provide increased lighting and are suitable for use in both commercial and household settings.


Another generation of LEDs, known as chip on board (COB) lights, provides more illumination than surface-mounted diodes (SMD) and gives the user more leeway in directing the light beam. When measured in terms of watts per lumen, it performs well, indicating a high level of efficiency

6- Graphene LED

In late 2015, the BBC reported that LED filaments laced with graphene were the most widely accessible kind of artificial light. They also said that consumers may expect a 10% reduction in their monthly energy costs while paying less for the bulbs themselves. A Russian researcher working out of Manchester University first discovered how to put graphene to use. The war has officially begun, and it will aid in the discovery of new and durable material applications.

7- Traditional and Inorganic LEDs

It’s made from inorganic materials and comes in a classic form that incorporates a diode. Compound semiconductors such as gallium arsenide phosphide, aluminium gallium arsenide, and many more are used to create the most extensively used LEDs. The materials used determine the colour of the LED light.

LEDs are personified as little lights that appear on control panels to indicate the different LED formats and kinds. Surface-mounted LEDs, flashing LEDs, multicolor and bicolor LEDs that may be driven by variable voltages, single-colour LEDs in 5mm, and an alphanumeric LED display are all types of inorganic LEDs. Large numbers of these inorganic LEDs are expected to become available soon.

8- Maximum Brightness LEDs

Inorganic LEDs, which include both high-intensity and high-brightness varieties, have begun appearing in domestic lighting and decorative settings. Because they are as efficient as inorganic LEDs at producing light, such LEDs are quickly gaining widespread use. Maximum light output from an LED requires power consumption and current levels that are within reasonable limits. In order to reduce the amount of heat given off, the LED may be placed atop a heat sink.

In terms of energy savings, the LED is a significant alternative to many more conventional light sources. The use of automatic lamps in the home is becoming widespread. Superiority over CFLs, compact fluorescent bulbs, and incandescent tube lights in terms of environmental impact and energy efficiency. When HBLEDs are turned off and on repeatedly, their efficiency reaches its peak, and they last for a long time. However, the lifetime of such bulbs has a limit that cannot be overlooked.

9- Organic LED

The organic LED uses the same principle as traditional LEDs. It’s clear from the name that the LED is constructed from organic substances. The light from the basic light emitting diode is emitted via specialised PN junctions made from inorganic semiconductors with varying amounts of dopant. Thin sheets of organic LED material are employed to create the display’s diffused lighting.

Mostly it is a thin film printed on a glass substrate. The electrical charges that make the LED light up were sent to the pixels inside the LED by a circuit made of semiconductors. LED technology keeps getting better and better, and it can be used in any field.

The wattage of the bulb shows how bright it is, and it works fine just like incandescent bulbs. But LEDs use a small fraction of the power that other lights do to make the same amount of light energy, which is why they are popular and useful in all industries. Now, they come in many different styles and colours, which helps them keep up in the world of electronics, which is very competitive.
