CN202142266U - LED shaker - Google Patents

Abstract

The utility model discloses an LED (Light Emitting Diode) swing, comprising a control module, wherein the control module is connected with a power module, a mercury switch, a display module and a button respectively. The LED swing is controlled by a single chip, and when the swing body swings leftwards or rightwards, the LED lamp changes with different swinging positions, so that a series of integral characters are generated for the effect of persistence of vision.

Description

LED shaker

technical field

The utility model belongs to the technical field of electronic entertainment products and relates to an LED rocking stick.

Background technique

In many occasions of indoor and outdoor competitions, performances, and evening parties, the rocking stick is often used by people to enliven the atmosphere of the scene and arouse the enthusiasm of the audience. However, most of the existing rocking sticks can only emit a single light, and their functions are relatively single.

Contents of the invention

The purpose of the utility model is to provide an LED rocking stick, which can display various characters and images. the

The technical solution adopted by the utility model is that an LED rocker includes a control module, and the control module is respectively connected with a power supply module, a mercury switch, a display module and buttons.

The utility model is also characterized in that,

The control module adopts STC89C52 single-chip microcomputer.

The power module consists of three 1.5V dry batteries.

The display module consists of 16 bright LED light-emitting diodes.

The beneficial effect of the utility model is that, through the control of the single-chip microcomputer, the LED light can change with the different shaking positions when the rod body is shaken left and right, and a series of complete characters can be produced due to the persistence of vision effect.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The structure of the LED shaking stick of the utility model, as shown in the figure, comprises a control module 2, and the control module 2 is connected with the power supply module 1, the mercury switch 3, the display module 4, and the button 5 respectively.

Among them, the control module 2 adopts STC89C52 single-chip microcomputer.

The power module 1 is composed of three 1.5V dry batteries.

Wherein the display module 4 is composed of 16 bright LED light-emitting diodes.

The working principle of the utility model is that the power supply module 1 provides the drive for the LED rocker, and when the LED rocker is shaken, the mercury switch 3 can determine the position of the LED rocker, so that the control module 2 can perform data processing , to send a signal to make the display module 4 display different content at different shaking positions of the LED shaking stick, and then use the visual persistence effect to allow the user to see a series of complete text or pictures, and press the button 5 to switch the display content.

The control module 2 adopts STC89C52 single-chip microcomputer, and the display module 4 is composed of 16 bright LED light-emitting diodes. The points are respectively connected to the two external interrupts P3.2 and P3.3 of the STC89C52 microcontroller. The default is high level. Different content is displayed in different positions. The power module 1 is composed of three 1.5V dry batteries to provide driving for the LED rocker.
