Classification: CPC F  H | IPC F  H

Claim 15:
16. The light-emitting diode (LED) lamp of claim 1, wherein:
the LED lamp further comprises a voltage sensing circuit configured to sense a terminal voltage of the rechargeable battery; and
the user interface section further comprises a test button and a third indicator,
wherein:
when the test button is depressed, the controller circuit is configured to operate the one or more LED arrays in a battery test mode for a first predefined period by: (1) disabling the first driver to supply the first internal power to the one or more LED arrays, (2) disabling the charging circuit to provide the second internal power to the rechargeable battery, (3) enabling the second driver to draw the third internal power from the rechargeable battery, (4) enabling the second driver to supply the fourth internal power to light up the one or more LED arrays, and (5) sampling a portion of the terminal voltage of the rechargeable battery via the voltage sensing circuit; and
in an event that the terminal voltage of the rechargeable battery drops below a predefined percentage relative to a nominal voltage during the battery test mode, the controller circuit is configured to set off the third indicator to indicate the battery test having failed exit out of the battery test mode, and resume an operation in the normal mode.
