Future of Lighting Industry

We are all acquainted with LED (light emitting diode). It is a semiconductor light source and was introduced as a practical electronic component in 1962. Earlier, LEDs emitted low-intensity red light but now the scenario has completely changed. We can now count LEDs under GREEN electronic component. They are tiny but efficient. Technology has made it possible in achieving efficiency with LED lighting.

LEDs pros and cons

Let us first look at it with a positive perspective.

LEDs are supposed to be the future of our lighting industry. They require low power for illumination. The power required for illumination is as low as required for a flashlight or the screen of our cellphone.

LEDs are very useful to light up smaller rooms. Bright white light can be achieved with minimum requirement of electric power. It has been used by the lighting designers. They can be very easily integrated with the false ceiling in any mall or showroom. Since, the requirement for the number of lights is larger in a showroom, LEDs are a very superior and an economical alternative since they are efficient and at the same time consume less electric power. I would say this is great way to embrace sustainability.

Now, let’s look at it with a perspective that will help us understand the shortcomings in LEDs technology. We will also discuss how researchers have found a perfect way to overcome these shortcomings.

As we already know that LEDs require minimum power to attain efficiency in lighting. The biggest drawback was that if we were to increase the current to increase its lighting efficiency (making it brighter) in order to light up the entire room with just one light, their efficiency nosedives. This is called LED droop.

Research on LEDs to attain maximum efficiency

Researchers have worked very hard to get LEDs into the counting list of sustainable electric components. They have now found a way to improve the brightness efficiency of the LEDs without having to increase their intake of power. The idea of using efficient LED lighting is appealing to people from developed countries as well as developing countries who want to run a light on limited power.
