More Information
Summary:An apparatus for displaying insufficiency of battery power, comprising: a driving circuit having a microprocessor (driving IC) or switching element with two ends respectively connecting to positive end or negative end of battery, the another end of said microprocessor (driving IC) or switching element is also connected to the positive end of said battery via a resistor and a first light emitting diode (LED), characterized is that: the apparatus further includes a low voltage detecting circuit or switching circuit having a low voltage detecting element and a second light emitting diode (LED), when said microprocessor or switching element performs a general displaying and said low voltage detecting element detects the insufficiency of battery power, the first LED and second LED performs lightening a combination of light with color different from the light from first LED, such that the insufficiency of battery power is detected.
