Abstract
The present invention provides a flashlight, and more particularly a flashlight with two different color lights and flicker frequencies. The flashlight comprises an anterior main body having a lamp housing, a posterior main body having a battery holder, a connecting base used to connect with the battery holder, and a starter for turning on/off the flashlight. Wherein the lamp housing is primarily configured to include a light-emitting chipset and a lens, and the battery holder is configured to accommodate a battery for supplying power. The light-emitting chipset of the present invention comprises at least two LED light-emitting chips that can generate different color lights, and a flicker frequency difference between said two different color lights is at least about 50 Hz. The shocking and dazzling effects of the flashlight are therefore improved by means of these two alternating flashing lights with different light colors and flicker frequencies such that the purposes of self-defense and/or countering and subduing an adversary can be achieved. Moreover, said light-emitting chipset may further comprise a third LED light-emitting chip to generate a non-flashing white light. Such fla…
