| Abstract | Due to light emitting diode (LED) with better performances , the demand for developing LED Street Lighting is growing continuously. Nowadays, a topic of interest in this context is the search for electronic driver in order to take advantage of LED performances. This work focuses in saving potential pitfalls during intelligent driver design procedure. To meet the LED street lighting application, the intelligent driver is based on our patented LED modules, which derived from the thermal, photometric, power electronics techniques. The intelligent driver includes: 1) an AC/DC converter, designed in a Quasi-Resonant Operation flyback topology to maintain high efficiency and constant current/voltage output of 800 mA/31 V with variable voltage output at wide input voltage range of 100-250 V/AC; 2) Also, the intelligent street lighting controller which performs the function of soft startup, Full ON, Hall ON and OFF is achieved. By setting an example of a 50 W LED pole head design, the suggested driver has been conducted in order to illustrate the complete process and results, which shows 72% more energy savings compared with conventional street lighting after 3 month running. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
