Abstract
A portable lighting device including a shell, at least one luminous element, a lens component, a battery compartment, positive and negative terminals, at least one indicator mark disposed on the battery compartment, and light-transmitting channels is provided. The battery compartment is made of transparent and fluorescent materials. The indicator mark is used for indicating the positive or negative terminals. The light-transmitting channels allow the light emitted by the luminous element to irradiate and stimulate the battery compartment to emit light and exhibit an afterglow. Thus, by using the light from the battery compartment to illuminate the indication mark, the user can accurately determine the positive and negative terminals in the battery compartment in a dark environment, which is convenient to replace batteries or battery pack.
