摘要

An electronic device (20) capable of adjusting light emitting frequency includes an oscillator (21) used to generate an oscillation signal (So), a microcontroller (23) connected to the oscillator (21), and a light emitting module (24) connected to the microcontroller (23). The microcontroller (23) is used to define that an oscillation times of the oscillator (21) within a unit time period (t) is an original quantity of oscillation times (n0). The microcontroller (23) sets a correspondence between a switching period and the original quantity of oscillation times (n0). The microcontroller (23) is further used to receive the oscillation signal (So) to calculate a time elapse. The microcontroller (23) is adapted to control on or off of the light emitting module (24) according to the switching period and the time elapse.
