Abstract

The invention discloses a flashlight with an adjustable optical domain. The flashlight with the adjustable optical domain comprises a cylinder and a lamp holder. A lamp body is arranged in the lamp holder. A reflective mirror surrounding the lamp body is further arranged in the lamp holder. An adjusting mechanism for adjusting the angle of the reflective mirror is arranged between the reflective mirror and the inner wall of the lamp holder. The adjusting mechanism comprises a driving gear and a driven gear which are meshed with each other. The driven gear is fixedly connected to the outer side wall of the reflective mirror. The driving gear is connected with an adjusting knob arranged on the outer wall of the lamp holder through a shaft. According to the light reflecting principle in physics, the light path is changed by changing the deflection angle of the reflective mirror in the lamp holder, and therefore the purpose of changing the optical domain of illumination is achieved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a flashlight. Background technique [0002] The flashlight is a mobile lighting tool commonly used in daily life, which is easy to carry and light. A flashlight usually includes a cylinder and a lamp holder. A battery is installed in the cylinder, a lamp body for lighting is arranged in the lamp holder, and a switch is provided on the cylinder. However, since the lamp holder is a fixed structure, the lighting area of ​​the flashlight is fixed and cannot be adjusted, which is easy to use. Problems such as light leakage occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flashlight capable of changing the lighting range to meet lighting requirements. [0004] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows. [0005] The flashlight with adju...
