In ancient times, people in Nepal used oil lamps (Diyo) made from clay or metal. These lamps were fueled with mustard oil or ghee and were widely used in homes, temples, and religious ceremonies.
Even today, lighting a diyo remains an important cultural practice during festivals like Tihar and Diwali, symbolizing prosperity and the victory of light over darkness.
Electricity arrived in Nepal in the early 20th century. One of the earliest hydroelectric projects was the Pharping Hydropower Station, which started generating electricity in 1911 during the Rana period.
This historic project marked the beginning of electric lighting in Nepal. However, electricity was initially available only in limited areas of Kathmandu.
After the 1950s, Nepal gradually expanded its electricity network. With the establishment of Nepal Electricity Authority, power generation and distribution improved across the country.
Traditional incandescent bulbs became common in homes, offices, and streets.
Today, Nepal is rapidly adopting modern lighting technologies such as LED bulbs, smart lighting systems, and solar lights. These technologies are:
Energy efficient
Long lasting
Environmentally friendly
LED lighting has significantly reduced electricity consumption in homes and businesses.
With increasing focus on renewable energy and smart technology, Nepal’s lighting future looks bright. Solar-powered lights, smart home systems, and efficient LED technologies are becoming more common.
As technology continues to evolve, lighting will play an even greater role in improving safety, productivity, and quality of life across Nepal.
प्रकाश मानव सभ्यताको महत्वपूर्ण हिस्सा हो। नेपालमा प्रकाशको विकास परम्परागत दियोबाट आधुनिक LED बत्ती सम्म आइपुगेको छ।
पुरानो समयमा नेपालका मानिसहरूले माटो वा धातुको दियो प्रयोग गर्थे। दियोमा तोरीको तेल वा घ्यू प्रयोग गरिन्थ्यो।
आज पनि तिहार र दिपावली जस्ता पर्वहरूमा दियो बाल्ने चलन रहेको छ, जसले अन्धकारमाथि उज्यालोको विजयलाई जनाउँछ।
नेपालमा बिजुलीको सुरुवात सन् 1911 मा फर्पिङ जलविद्युत आयोजना बाट भएको थियो। त्यस समय राणा शासनकाल थियो।
सुरुमा बिजुली काठमाडौं क्षेत्रमा मात्र सीमित थियो।
1950 पछि नेपालमा बिजुलीको विस्तार हुँदै गयो। नेपाल विद्युत प्राधिकरण स्थापना भएपछि देशभर विद्युत सेवा विस्तार भयो।
यसपछि घर, कार्यालय र सडकमा इन्क्यान्डेसन्ट बल्ब प्रयोग हुन थाले।
आज नेपालमा LED बत्ती, सोलार लाइट, स्मार्ट लाइटिंग जस्ता आधुनिक प्रविधिहरू प्रयोग भइरहेका छन्।
यी प्रविधिहरूका फाइदा:
कम बिजुली खपत
लामो समयसम्म टिक्ने
वातावरणमैत्री
नेपालको प्रकाशको भविष्य
नवीकरणीय ऊर्जा र नयाँ प्रविधिको विकाससँगै नेपालमा प्रकाशको भविष्य अझ उज्यालो हुँदैछ। सोलार बत्ती र स्मार्ट लाइटिंग प्रविधि विस्तार हुँदैछ।
