Claims

[Claims for Utility Model Registration] 1. In order to drive the light emitting diode 1 with the power battery 2 to emit light and obtain illumination, a DC-DC converter is provided, and the DC-DC converter is turned on and off. An ear pick with light-emitting diode lighting, characterized in that a self-holding circuit H consisting of a logic circuit that operates in response to a command signal voltage activates and stops a DC-DC converter. 2. The earpick with light emitting diode illumination according to claim 1, wherein six NAND gates G of the logic element of the self-holding circuit H are replaced with two NOR gates. 3. The battery case 2-b is replaced by the battery case 2-a, and the battery case 2-a is not provided with a DC-DC converter. An ear pick with light emitting diode lighting as claimed in claim 2 of the utility model registration. 4. The earpick with light emitting diode lighting according to claim 3, wherein the operation of the self-holding circuit H constituted by a logic circuit is replaced by a tumbler switch 10. 5 DC-DC in power supply circuit body A that has a DC-DC converter in battery case 2-b
It is characterized in that the converter is turned on and off using a tumbler switch 10. An ear pick with light emitting diode lighting as claimed in claim 2 of the utility model registration.
