Lighting lamp controller lighting with broadcasted music or bell sound

Abstract

The invention discloses a controller of light emitting lamp emitting light with the playing of the music or ring, including central control module, light emitting lamp control module and multicolor light emitting lamp set; where the light emitting lamp control module generates a series of drive signals changing with the rhythm of the played music or ring, according to the control instructions coming from the central control module, the drive signals are to be inputted in the multicolor light emitting lamp set to control the on and off states and brightness change of light emitting lamps of different colors, so as to make the color of the multicolor light emitting lamp set and the composed pattern change with the rhythm of the played music or ring. The multicolor light emitting lamp set isa three-basic color light emitting lamp set, the drive signals are red, green and blue three-basic color PWM signals, where their duty factors determine the color of the multicolor light emitting lampset, and the proportional change of their duty factors is consistent with the rhythm of the played music or ring. Relative to exiting technique, the invention has the characters of simple structure,good visual effect, strong practicality, etc.

Description

technical field [0001] The invention relates to a light-emitting lamp controller used on digital products with music or ringtones, such as mobile phones and MP3 players, to emit light when the music or ringtones are played. technical background [0002] At present, some digital products, such as mobile phones, MP3 players, CD players and other products, usually associate the rhythm of music with LED lights in order to visually produce a rhythm effect when playing music or ringtones. Some major manufacturers now associate the rhythm of music with the on and off of LED light-emitting lights, that is, the LED light-emitting lights are turned on and off rhythmically with the rhythm of music or ringtones. Although this scheme produces a rhythmic change visually, the visual change is relatively monotonous because it only changes in light and dark but not in color. Contents of the invention [0003] The object of the present invention is: aiming at the deficiencies of the prior ...
