Frequency-variable breathing lamp and control method thereof as well as main machine peripherals

Abstract

The invention relates to a frequency-variable breathing lamp and a control method thereof as well as main machine peripherals. The control method comprises the following steps as follows: step 1, a data collecting module collects a data flow communicated with a main machine of a micro-control unit, and records a data report rate of the data flow; step 2, a PWM (Pulse Width Modulation) module modulates the data report rate to a PWM pulse sequence corresponding to a pulse period according to a modulation table, wherein the modulation table is an algorithm function between the data report rate and the pulse period; step 3, a power supply integration module converts the PWM pulse sequence into a controlled riving power; and step 4, the micro-control unit controls power variation of a light-emitting unit according to the driving power provided by the power supply integration module; and the step 1 to the step 4 are repeatedly executed every n seconds. The frequency-variable breathing lamp provided by the invention can be subjected to rhyme variation with working load of a main machine peripheral product, so that the breathing lamp displays in a more vivid and natural manner, and the eye fatigue is effectively relaxed.

Description

technical field [0001] The invention relates to a control method of a light-emitting indicating device and a device thereof, in particular to a control method of a variable-frequency breathing lamp, peripherals of a host computer, and a variable-frequency breathing lamp. Background technique [0002] Luminous indicator lights are used in various electronic devices. The indication effects of computer peripherals have always attracted the attention of consumers. In the current host peripheral products, the usual luminous effects are relatively simple, such as continuous light or Flashing at a fixed frequency, although the visual effect of the breathing light flashing at a fixed frequency is better than that of the continuous light indicator, but the rhythm of this breathing light is rigid and rigid, not vivid and natural, and the flashing at a fixed frequency is easy to cause visual fatigue and the breathing effect poor. Contents of the invention [0003] The object of the ...
