That small dot of light that one sees all around holds business potential that is only starting to ripen
For the longest time, incandescent bulbs, which replaced lanterns, reigned as the solution for lighting the world over. Compact fluorescent lamps (CFLs) that consume less power to get as much lighting are slowly and steadily gaining acceptance in the market.
As a result incandescent bulbs will soon be shelved for good. However, even as CFLs are gaining momentum, they already have an emerging threat in the form of an even lesser power consuming and higher-efficiency technology—light-emitting diodes (LEDs).
|What it is, how it works|
|A diode, the simplest sort of a semiconductor device, is a material with a varying ability to conduct electrical current. Light-emitting diodes (LED), in layman’s terms, are just tiny light bulbs that fit easily into an electrical circuit. However, unlike ordinary incandescent bulbs, they don’t have a filament that will burn out or get hot. It is solely the movement of electrons in a semiconductor material that illuminates LEDs1. The color of the emitted light depends on the composition and condition of the semi-conducting material used, and can be infrared, visible, or ultraviolet. Simply put, blue, green, and red LEDs can be combined to produce any color, including white.|
The stage is already set for LEDs to take over as the next big thing in the lighting industry. The act is in its making. LEDs are already penetrating into homes and businesses, but mostly as a decorative lighting solution. For regular indoor lighting though, not much is being done. Not to say that it does not hold the potential to do that. All that is required to ride on this new wave of lighting technology is innovation.
What the market is ready for and what is not being offered are LED-based products for regular indoor lighting at an affordable price.
Can you give our readers an overview of the lighting industry in India?
Of late, lighting as source of energy has become a hot topic of discussion and debate globally. According to the International Energy Agency:
This has lead to the growth in energy-efficient lighting, which can play a significant role in assuaging the impact of global warming.
As per a report by the International Energy Agency, the adoption of more energy-efficient lighting systems could prevent a cumulative total of 16 billion tons of carbon from being added to the world's atmosphere over the next 25 years. Despite advances in lighting technology, between 67% and 75% of the world’s lights utilize older, less energy-efficient technology——some dating as far back as the 1950s.
Tell us more about the advent of LED-based lighting solutions in India.
In 2007, an LED lighting range was launched for Indian homes, which includes an array of products for innovative energy-conserving lighting solutions. These products feature saturated colors, digital control, energy efficiency and such.
The advantages of LEDs include longer lifetime, compact size and flexibility in design, digital control programmability, light output with no ultraviolet and infrared radiation and usage safety because of low voltage and low heat operation. These will expand applications of lighting in homes in ways one could only dream of a few years back.
We believe that LEDs is the next wave of lighting technology. LED lighting systems provide a much higher color saturation and brilliance than by filtering conventional light sources. Different color effects are now possible from the same light source. Prior to this, LEDs have been used in many architectural and commercial applications. Now, home users can utilize LEDs for decorative purposes, save energy and reduce their electricity bill. Recently, we have introduced LED-based products for office, shop and city beautification segments in India.
Recently, at the Light India International 2008 exhibition held in Delhi, we showcased our innovative and futuristic lighting solutions in office, urban, retail, hospitality and consumer lighting segment through concepts like future bazaar and experience zones.
Typically, who would you say are the current target clients for LED-based lighting globally?
Where is the market—India or abroad?
LEDs consume less power and have higher energy efficiency than CFLs or incandescent light sources and have an extremely long lifetime, which means the product produces more or less no ‘waste’ in the form of spent light bulbs. LEDs do not contain any mercury. They can actually cut down that electricity bill manifold, even in comparison to compact fluorescent lamps (CFL).
The best thing about LEDs is that even though they are really small in size, the light emitted is really bright. This fact itself opens up a vast canvas for innovation in making products. The trick is to house LEDs in a variety of fixtures.
Further variations of LEDs include organic light-emitting diodes (OLED), polymer light-emitting diodes (PLED), light-emitting polymers (LEP), flexible OLED (FOLED), and phosphorescent OLED (PHOLED). These variants have been put to innovative use in apparel displays, etc.
