The data judging unit 71 M265770 obtains from the command signal whether the hail corresponding to the beat belongs to the RGBLED unit 7 and 0 = Light color content, and it is judged that it is yuan 72, this data temporary storage unit = the light color of the performance;-the data temporary storage single shift register is implemented according to the light color content temporary storage series, Bits such as: 8-bit data, if the information is not sufficient, ^, said that the early storage 72 will temporarily store the light-colored content data output by the data judgment unit 71, and the judgment of the early data judgment sheet S 7 i will be saved ^ 2 Five beasts take early (7 3 '72 temporary recordings of silk robes, temporary recording unit of each RGB LED unit 70), it is difficult to obtain the light color content required to respond to the beat, and the light color Content 2 temporary: in the data temporary storage unit 72. If the data judging unit 71 judges this light: The content does not belong to the light color that the RGB LED unit 7G needs to express, the data oblique storage unit 72 does not need to store the data of the light color content. If the judgment of the material is 71, it is judged that the light color content belongs to the LED unit%, and the data acquisition unit 73 retrieves the data of the light color content temporarily stored by the data temporary storage unit 72, and the control circuit 74 internally processes to The signals of the PWM type drive the light-emitting elements 81, 82, and 83, and the RGB LED unit 70 presents the light color required to be expressed in accordance with each beat. Please refer to the fourth and fifth figures again. In the second embodiment of the present invention, the RGB LED unit 70 includes a control circuit 74 to drive the internal light emitting elements 81, 82, and 83. Therefore, the present invention simplifies the circuit board (PCB) of the light emitting device. ) Layout to save more space, and the RGB LED unit 70 is easier to implement on a variety of products that change color with the music beat, which makes the planning of the product extremely flexible and expandable. For product designers, it is easy to add RGB LED units. 70 number. In a specific embodiment, the packaged product of the RGB LED unit 70 has only four pins, of which two pins are used as power pins and ground pins, and the third and fourth pins are A command signal and a clock signal from the microprocessor 20 are respectively received, and the clock signal is a frequency corresponding to the data content of the command signal 11M265770. In the second embodiment of the present creation, three RGB LED units 70 are taken as an example. When the microprocessor 20 receives a beat signal from a sound source and outputs the light color content of each RGB LED unit 70, the microprocessor 2 〇 can directly output a command signal specifying one of the RGB LED units 70, and each rGB LEd unit 70 obtains the command signal according to the clock signal, and determines whether it belongs to the light color that needs to be expressed. If the RGB LED unit 70 receives a command signal that does not belong to the light color to be expressed, the RGB LED unit 70 maintains the original light color. If > If the RGB LED unit 70 receives the light color belonging to itself which needs to be expressed, the 7L day guard, the RGB LED unit 70 will be internally equipped with light emitting elements 81, 82, 83, so that each RGB LED unit 7〇Πί, gauge: 1] light color. When the microprocessor 20 receives the next beat signal, it repeats the above ^^^. In this creation, the lighting device can change color with the music beat. Receive the instruction signal. According to the embodiment, the data judging unit of the control circuit is connected to a different degree of complexity. The data judging sheet of the circuit design 65 of the data judging unit: the light emitting module implemented by Kang second figure. Application instruction letter of the control circuit device: 61 Only one data line is required to receive the change from the micro processor / 'so the data judging unit 61 must judge whether the data line starts to receive the serial instruction signal according to the third figure; The root 71 is the reference time ^ \ forehead. The control circuit 74 accurately judges the serial command on the data line by making the judgment unit number 0S.
