Abstract

The invention provides a flashlight with a diffusion plate, belongs to the technical field of lighting, and aims at solving the problems of single direct lighting, complex structure, common material and short service life of the flashlight. The flashlight with the diffusion plate comprises a flashlight body, a lamp cap assembly and a lamp tail assembly, wherein the lamp cap assembly and the lamp tail assembly are respectively mounted and sealed at two ends of the flashlight body; a battery pack is mounted in the flashlight body and is electrically connected to the lamp cap assembly and the lamp tail assembly. The flashlight with the diffusion plate further comprises a refracting plate; the flashlight body is prepared from copper alloy; the refracting plate comprises a refraction layer, a reflecting layer and a shielding layer, wherein the reflecting layer and the shielding layer are respectively clung to two side surfaces of the refracting layer; the refracting layer is prepared from light transmitting material; the refracting layer and the shielding layer are both manufactured from lightproof materials; the lamp cap assembly is cylindrical; a mounting hole is formed in the shielding layer; an axis of the mounting hole is vertical to the refracting layer; the lamp cap assembly can be inserted into the mounting hole, and the light can be refracted to the surroundings along the refracting layer. The flashlight is reasonable in structure; all parts are manufactured from specific materials, so that the service life of the flashlight can be prolonged.
