PURPOSE: An LED(Light Emitting Diode) driving device is provided to improve the efficiency of driving control by containing multiple first and second switching elements and a control part. CONSTITUTION: Multiple LED parts(220a,220b,220c) are connected in parallel with each of multiple storage battery parts(210a,210b,210c). Multiple first switching elements(230a,230b,230c) control the on-off of each LED part. Multiple second switching elements(240a,240b,250a,250b) change the connection shape of the multiple storage battery parts. A control part(280) controls the on-off of the second switching elements in order for the storage battery parts to be connected in series. The control part controls the on-off of the second switching elements in order for the storage battery parts to be connected in parallel. [Reference numerals] (280) Control part
