SOLAR POWERED STUDY LAMP

摘要

The invention consists of Solar PV Panel, Light source encased in a ABS plastic casing, DC to DG converter, Storage device, Integrated circuit having features to control the charging/discharging of the storage device, Push button to put the light source ON/OFF, Tri color LED to indicate the state of the storage device, such that solar power is converted into DC power using Solar PV Panel and stored in storage device whose charging or discharging is controlled by integrated circuit and when push button is depressed, integrated circuit delivers the power to the light source and light source emits light. In another aspect, this invention consists of a goose neck connection. In yet another aspect, this invention consists the DC-DC converter that ensures low output ripple. In yet another aspect, this invention consists a high frequency circuit that ensures that the electronic components in the PCB have smaller size. In yet another aspect, this invention consist of a low standby current. In yet another aspect, this invention consist the Tri color LED which shows orange indicator when the storage device is charging and green indicator when the storage device is 100% charged and red indicator when the storage device is 100% discharged;
