| Summary: | This study presents a portable rechargeable battery with DC to DC converter for power Light Emitting Diodes (LEDs) lighting system. This study is undertaken to develop a LEDs lighting system as a functional primary lighting without connecting to the electric supply. Moreover, the system is design to replace the generator set at the night market. The system uses the rechargeable battery as an electrical energy to the driver (DC to DC converter) and the load (power LEDs). This is a low system whereby the lifetime is very long, easy to use and aims to reduce the cost of maintenance using the generator set. This topology is based on a battery charger and combine with simplifies converter method on the same circuit to reduce the number of the component. A prototype circuit that is designed from input AC source (240V) by using the transformer and bridge rectifier to step down (12V) charge the battery 12VDC. The output load (power LEDs) 16V - 36VDC is controlled by the ballast converter. The results show the functionality of the overall system and prove that the LEDs lighting lasts for more than 6 hours operation by using the system and an effective solution to replace the generator set. |
