LED Based Solar Lights

Introduction

LED stands for Light Emitting Diode. it is a solid state device that can emit light when electric current passes through it. A solar lighting system based on LED is a system that comprises of a photo voltaic module. These lights are a joint venture of LED(s), electronics and some batteries that usually places in a suitable house and is usually made up of plastic, fiberglass or metal. The electricity is generated through a photovoltaic module that in turn charges the battery. It is one of the best feature is that it is a portable device that is suitable for both outdoor and indoor lightning, thus covers full 140 degrees of range around it. Shortly, it can be explained as the LED based solar lights aim to provide solar electricity that operates LED lights during some specified hours per day. Talking about LED, LED is nothing but a simple p-n junction based device that can emit light when a forward current passes through it.

Generation of initial thoughts

There are 1.6 billion people in the world without access to electricity who rely on kerosene, candles and other fuel-based sources for lighting. D.light has developed solar-rechargeable LED lanterns to provide bright, clean and affordable alternatives to kerosene lanterns.

Solar lanterns are designed by D.light to be low cost, high quality and durable.

Products developed, tested and designed by D.light's own design team located in Hong Kong and manufactured and assembled in China.

There are three basic models: Nova, Solata and Kiran, ranging from 0.3Wp to 1.3Wp. All use LED lights.

D.light develops its products based on hundreds of hours of field research with end users in India, Africa and elsewhere.

Solar lanterns cost end users between US$10 and US$45, depending on the model.

D.light has sold over 220,000 solar lanterns in 32 countries, with main markets in India and East Africa. Lights are benefiting around 1.1 million people.

Solar lanterns sold to date are reducing CO2 emissions by 44,000 tonnes a year.

PV lanterns allow children to study for longer hours and more effectively.

Other benefits include extended shop hours, more efficient agricultural activities, mobile phone charging facilities and craftwork in the evening.

Brief overview and specification that fits best

The products will be developed, designed and tested by design team, located in UK. They are manufactured and assembled in China. Develops its products based on hundreds of hours of field research with end users in India, Africa and worldwide, and is therefore able to provide customers with a product they want.

Markets that will be targeted will be the lanterns directly to rural customers, using road shows, sales vans, and go-to-market campaigns. It markets the products through distributors, dealers and rural entrepreneurs (REs). REs are local entrepreneurs who buy a few solar lanterns at a time from dealers and sell them at a profit in their own village. Local dealers and REs explain the benefits of the lights and stage demonstrations in markets and ...
