India needs “Light revolution”. We need light at cheapest cost. We need LED technology to achieve this. We need Solar technology to achieve this. We need combination of these two technologies to make sure not a single kid in a distant INDIAN village is deprived of doing homework at night, because simply there is no light in his/her hut.Forget about good house, we need “Light” first. It is one of the basic necessity after food and shelter. Because it is directly related to the education of children and future generation. It is directly related to why most of our children leave school at rural distant population ? It is related to why our rural agrarian economy is not becoming profitable ? , just because adult literacy is not increasing and there is no culture of reading at night. Simply because there is no “Light”.
Just like decades before, we were at the brisk of poverty and our majority of population was going hungry, we created a “Green revolution”. Now we are in a position to feed at least majority of population because we started growing variety of crops and we became self-sufficient partially.It happened because of efforts of our scientists , leaders and farmers who participated to achieve this.
Light is costly even today for majority of our INDIAN village population considering their per capita income and economic situation.In addition to this lack of poor electrical infrastructure, the end result is that electrification is only on papers and in numbers of government files. 96% villages are electrified as per government numbers, but in reality it is far from having all homes running
all kinds of equipment(s) on it. Only 60% of INDIAN villages are able to harness full power of electricity even in 21st century. Off course, we are giant in IT and Software Industry.It is a bitter truth.
I was fascinated by LED(s) right from my engineering college days. In those days, hardly white LED(s) were available. We used to get red and green LED(s) very easily. I was surprised with the fact that a small amount of DC voltage was able to generate so much of Luminosity. A modern white LED light bulb converts more than 50 percent of the electricity it uses into Light. Please compare that to the 4 percent conversion rate for incandescent bulbs.LED(s) also last up to 100,000 hours (almost 20 years), compared to 10,000 hours for fluorescent lights and 1,000 hours for incandescent bulb. A white LED light is easy to make from a blue one. Engineers use a blue LED to excite some kind of fluorescent chemical in the bulb. That converts the blue light to white Light. Our whole world is grateful to Isamu Akasaki and Hiroshi Amano of Japan and U.S. scientist Shuji Nakamura for invention of blue light-emitting diodes for which they have been awarded Nobel prize of physics, a new energy efficient and environment-friendly light source. Because of blue-led light, it is now possible to create while LED Light.
We need pencil-cell operated LED tube light(s) for our INDIAN villages where electricity infrastructure has not reached yet or simply it is not working. We need motor-bike operated LED lighting system so that in day time people can drive motor-bikes and at night battery can be used to LIGHT the house. Motor-bike batteries can be charged at petrol pumps. There is tremendous need of solar operated LED lighting at cheapest cost of ownership and almost zero recurring maintenance cost. There is lot of scope for innovation in this area e.g. developing LED lighting system for farmers where light will be automatically switched off when no human will be present in their field(s) where high-yield crops are present.Also, village street lights operated on solar power which will be switched off in day time. Off course most of the products and technologies are available in the market, but we need to develop an Eco-system where it will be produced locally at every district level of INDIAN villages.
But our cities also need to be “Energy” efficient.We not only need LED lighting system for homes and shops to con-server energy , but also for our parking lots, empty galleries, darkened streets at distant locations in cities, ATM(s),railway platform(s), bus stand(s) , you name a place where secondary lighting is not required ?, everywhere it is required, and so LED lighting with conservation is required.
We need to build start-up ecosystem actually developing innovative product(s) in this segment. Sadly, most of our start-ups are focusing on technologies related to software product(s) or service(s).
It is high time they realize that energy conservation for masses is one of the biggest market in our country where at one end most of our village population is not able to access it even at higher cost and at other end urban population , they do not have means to conserve and economically use it.
