The embodiment of the invention discloses an electric torch circuit. The electric torch circuit comprises a main control chip, a triode, an LED (Light-Emitting Diode) lamp, a constant current chip, a GPS (Global Positioning System) module, a decoding chip, a wireless receiving module and a display module, wherein the PWM (Pulse Width Modulation) output end of the main control chip is connected with the base electrode of the triode; the emitting electrode of the triode is connected with an anode of the LED lamp; the constant current chip and the LED lamp are connected in parallel; the GPS signal receiving end of the main control chip is connected with the GPS module; the first input end of the main control chip is connected with the first output end of the decoding chip; the second input end of the main control chip is connected with the second output end of the decoding chip; the wireless receiving module is connected with the decoding chip; the output end of the main control chip is connected with the display module. Through the adoption of the electric torch circuit, the display for longitude and latitude at the current position and low power prompt on a PWM dimming electric torch can be realized, so that the user experience during outdoor exercises is improved.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a flashlight circuit. Background technique [0002] With the rise of outdoor sports, more and more outdoor equipment has emerged. Among them, the flashlight that plays a lighting role is particularly important. However, the existing flashlights have single functions, which often cannot meet various needs of outdoor users, such as GPS positioning and the like. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a flashlight circuit, which can display the latitude and longitude prompt of the current location on the PWM dimmed flashlight, improve the user's experience when exercising outdoors, and has the characteristics of simple circuit and low cost . [0004] In order to solve the above technical problems, an embodiment of the present invention provides a flashlight circuit, including a main cont...
