Abstract

The invention discloses a flashlight circuit for distance measurement. The flashlight circuit comprises a distance measurement circuit, a control circuit and a display circuit. The distance measurement circuit emits lasers after receiving a switching signal of the control circuit and outputs a feedback signal after receiving the reflected lasers. The control circuit receives the feedback signal output by the distance measurement circuit, calculates the distance according to the time difference between output of the switching signal and receiving of the feedback signal and outputs a display signal. The display circuit receives a calculation result signal and displays a calculation result. The flashlight circuit is integrated in a flashlight, the functions of the flashlight are enriched, the measured distance is long through the lasers, accuracy is high, the currently-measured distance is displayed through the display circuit, readability is improved, and the flashlight circuit is simple and convenient to implement.

Description

technical field [0001] The present invention relates to the field (technology) of electronic circuits, in particular to a flashlight circuit for distance measurement. Background technique [0002] At present, due to its convenience, flashlights are used in many occasions, but the function is single, which cannot meet some specific needs of users. For example, users need to know whether there are obstacles in front of them and the distance between them and the distance so far when they are exploring. , and the lighting length is limited, which cannot meet the needs of users. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flashlight circuit for distance measurement. The distance can be tested by laser, which solves the technical problem that a single-function flashlight cannot meet the distance measurement function. [0004] In order to solve the above technical problems, an embodiment of the present invention...
