Abstract
A luminescence controller of luminous ornament includes a lamplight program control chip IC2, a drive circuit, a luminous diode and a power amplifier IC1. The power amplifier IC1 is provided with an audio input terminal. The power amplifier IC1 is provided with an audio amplification output terminal 01, and the audio amplification output terminal 01 is connected with a triggering control pin of the lamplight program control chip IC2. The music signal is amplified by the power amplifier, and then the signal can be inputted to the triggering control pin of the lamplight program control chip IC2, and thus the lamplight program control chip can be triggered by the music signal endlessly, which makes the luminous diode flash and change the light brightness along with the music beat and the rhythm, and the luminous styles are much more.
Description
Technical field
The utility model relates to a kind of Luminous decorations, for example the light emission controller of the Luminous decorations on the Christmas tree.
Background technology
In the prior art, Luminous decorationses such as Christmas tree comprise light program control chip, drive circuit, light-emitting diode, the light program control chip sends control signal, and to carry out power amplifier rear drive light-emitting diode through overdrive circuit glittering, can be by multi-group light-emitting diode according to its luminous order of program control.But this luminous variation is by programme controlled, cannot readjust at the scene.
Summary of the invention
The purpose of this utility model is to provide a kind of light emission controller of Luminous decorations, can control the light program control chip by music, makes light-emitting diode to change with the beat and the intensity of music.
The technical solution of the utility model is: a kind of light emission controller of Luminous decorations comprises
Light program control chip IC2;
Drive circuit, the signal input part of described drive circuit connect the light controling signal output of light program control chip IC2;
Light-emitting diode, the signal output part of described drive circuit are connected on the described light-emitting diode;
It also comprises power amplifier IC1, and described power amplifier IC1 has audio input end, and described power amplifier IC1 has audio frequency and amplifies output 01, and described audio frequency amplifies the triggering control pin that output 01 meets light program control chip IC2.
The utility model compared with prior art has following advantage:
After amplifying through power amplifier, music signal can be input to signal the triggering control pin of light program control chip IC2, then the light program control chip can constantly be triggered by this music signal, make light-emitting diode can follow the brightness of beat and the rhythm flash of light and the variation light of music, luminous form is more.
