Abstract

The invention relates to a portable lighting device, in particular to a flashlight with an adjustable plane of illumination. The flashlight comprises a front lamp cap and a cylinder body, wherein the front lamp cap at least comprises two movable lamp bodies divided along the circumferential direction of the lamp cap, and each movable lamp body is movably connected with the cylinder body. The changes of the structure allow a user to adjust each lamp body freely, not only can control the plane of illumination and the direction of illumination, but also can adjust the intensity of illumination. Besides, when the electric quantity of the flashlight is low, the user can turn off part of the lamp bodies to maintain the illumination continuously. Compared with the conventional flashlight, the flashlight has stronger practicability and a simple structure, is easy to operate and is suitable for industrial production.

Description

technical field [0001] The invention relates to a portable lighting device, in particular to a flashlight with an adjustable illumination surface. Background technique [0002] Flashlights are widely used in industrial production and daily life because of their small size and easy portability. Most of the existing flashlights use diodes to emit light, and the lighting intensity is relatively large, so there is no need to adjust the focus distance. Therefore, the lamp head of the flashlight adopts a fixed structure, which makes it impossible for users to adjust the light surface and realize simultaneous lighting in multiple directions. . When the electric power of the existing flashlight is insufficient, because part of the luminous body cannot be turned off, the light intensity is relatively dark, and it cannot be charged in time, so it is very inconvenient to use. Contents of the invention [0003] In order to solve the problems of the existing flashlight that the illum...
