  • Publication number: 20240133544
    Abstract: A telescopic lighting structure includes a telescopic rod composed of a rod body and a detachable terminal rod. The terminal rod has a light-emitting module and a power switch. The light-emitting module and the power switch do not protrude beyond the surface of the terminal rod, thus the terminal rod can be completely retracted into the rod body, making it easy to store and protect the light-emitting module. A power supply assembly is provided inside the terminal rod. The power supply assembly controls the connection with the light-emitting module through the power switch. Through this structural design in which the power supply assembly, the light-emitting module and the power switch are arranged on the terminal rod, the telescopic rod can be stretched so that the light-emitting module has a higher lighting height. Further, the terminal rod can be removed to provide illumination alone, thereby increasing the scope of application.
