specific Embodiment

[0040] The input and output parameters of the control algorithm are composed of 6 input variable parameters and 4 output control variables. In this embodiment, the light-emitting diode LED1 is a green LED light, the light-emitting diode LED2 is a red light LED light, and the light-emitting diode LED3 is a blue light LED light. The processing module calculates and obtains 4 output control variables according to 6 input variable parameters, 4 The output control variable is used to output to the indicator light drive circuit to control the work of each LED light. Among them, 6 input parameters are BRTH, T, S, RI, GI and BI; 4 output variables are PWM, RO, GO and BO.

[0041] Description of each parameter:

[0042] BRTH: Breathing mode, an integer with a value range of 0-10, 0 means no breathing, 1-10 means 10 different breathing modes.

[0043] T: Breathing cycle, the value range is 0.1 seconds to 10 seconds, and the step is 0.1 seconds.

[0044] S: The speed of the brightness...

Abstract

The invention relates to a breathing light control circuit. The breathing light control circuit comprises a power supply modulation circuit, an indicator light drive circuit, a processing module and a plurality of light emitting diodes, wherein the light emitting diodes are respectively connected with the power supply modulation circuit and the indicator light drive circuit; the processing module is respectively connected with the power supply modulation circuit and the indicator light drive circuit; the processing module outputs signals to the indicator light drive circuit through a plurality of output ends, emits light through the light emitting diodes corresponding to the indicator light drive circuit, and controls the power supply of the light emitting diodes by outputting the signals to the power supply modulation circuit, so that the breathing effect of the light emitting diodes is further achieved. The breathing light control circuit has the characteristics of high use flexibility and low cost.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a breathing lamp control circuit. Background technique [0002] Breathing light refers to the gradual change of light from bright to dark under control, and the light is lit or extinguished with a clear rhythm like breathing. Breathing lights are generally used for indication or prompting, and are widely used in various electronic devices, such as mobile phones, which can effectively improve the indication efficiency of electronic devices and make the use of electronic devices more convenient. [0003] Traditional breathing lamps use an integrated drive circuit to drive LED (light-emitting diode) lights. Such a drive circuit has high cost, single function, and poor flexibility. Contents of the invention [0004] Based on this, it is necessary to provide a breathing light control circuit for the defects of high cost, single function and poor flexibility of the driving ...
