Description

Kyung sticks {Signal stick}

The present invention relates to a light rod, and more specifically, it is not a simple flashing operation, but in order to display a message by text or picture, image display due to the afterimage effect is accurate and the reliability of the operation is maintained regardless of the shape of the user shaking. It is about a light rod which can be.

Normally, the light rod is used as a substitute for hand signals of the police or the military as a tool for delivering a judo message to others through the flashing of the lamp, but in recent years, the use of the light stick is being expanded to be used for advertisements and cheering. When shaking the light rod, if the characters, symbols, and pictures such as 'stop', 'fighting' and '->' are displayed in the air due to the afterimage on the trajectory, the desired message can be delivered more accurately.

For this purpose, according to the Korean Utility Model Registration No. 20-0273281 (announcement date 2002.04.25) "Magic rod", `` In the pattern display device using visual afterimage effect, the light emitting body having a regular interval arranged vertically and located on the top of the device A switch for position determination using inertia is attached, and there is a switch for selecting the type and output form of the output pattern, and the light emitting body is used as a monitor indicating the type and output type of the pattern. The magic wand (writing of characters using afterimage effect) in which all operations are implemented is disclosed.

However, in the detailed description, The internal structure is a piece of metal attached to increase the inertia of the seesaw switch, which is not a detailed description due to the problem of replication.'It corresponds to an incomplete design lacking specificity. Failure to reflect the speed (cycle) as well as the stroke (starting point, end point) that shakes the rod does not accurately display the image in various forms of use.

Accordingly, the present invention focuses on the above-mentioned point, and provides a light rod that can maintain the reliability of operation while maintaining accurate image display due to the afterimage effect regardless of the size or shape of the trajectory of the user's shaking. The purpose.

Another object of the present invention is to display a plurality of characters and pictures rather than a single character and a picture display mode switch while maintaining the configuration of the flashing form that had in the conventional light rod.

1 is a front / side view showing an exploded light rod according to the present invention, and FIG. 2 is a block diagram showing a main circuit of the light rod according to the present invention. 7 is a perspective view of the light rod of the present invention.

The present invention relates to a light rod that displays characters due to afterimages on a moving trajectory, and the body of the light rod is divided into a 'handle portion' and an 'display portion' extending upward. 1A and 1B, the handle portion and the display portion are separated, and the display portion has an elliptical cross-section having a larger front width than the side surface.

According to the present invention, a plurality of LEDs 10 arranged in a straight line are provided on the display unit. The LED 10 uses a device that consumes low power and has high brightness and high visibility (for example, InGaAlP for road marking). Types containing phosphors can be used, or they can be arranged in rows rather than in rows to change the color during use.

According to the present invention there is provided a controller 20 for storing the on-off data of the LED 10 in the memory 24 and executed by the microcomputer 25 every stroke. The controller 20 is built in the handle portion of the body, and has an input portion 21, an output portion 22, a memory 24, a microcomputer 25 as main parts. The input unit 21 is configured to receive the input of the detection means 30 to be described later to convert to a digital signal, the output unit 22 is configured to drive each LED 10 independently on and off. The memory 24 stores and updates predetermined data for sending to the output unit 22 according to the signal of the input unit 21.

The shape of the trajectory of one stroke when shaking the light rod is not only varied in vertical arch, left and right arch, vertical horizontal movement, left and right vertical movement, but also the size of the trajectory can be changed, and the controller of the present invention using the microcomputer 25 ( 20 is associated with the detection means 30 to be described later to accurately implement the image set within the range of the trajectory despite any of the above conditions.

In addition, in order to implement an asymmetric image when there is a vertical movement or a left or right movement for realizing the afterimage effect by the hard rod, the same image is implemented when the object implementing the afterimage moves from the top to the bottom In order to be visible, we need a means to reverse the image that has been moved from top to bottom. This can be done by software processing by the controller 20 and the program.

The detecting means 30 according to the present invention is provided in such a manner as to input a speed and a stroke signal to move the one stroke to the controller 20. The detecting means 30 of the present invention is embodied in the first to fourth embodiments and refers to FIGS. 3 to 6 to be described later.

In addition, according to the present invention is provided with a mode switch 80 which is installed to select one of the subroutines stored in the controller 20. Specific characters, symbols, and the like to be represented as images are performed by respective subroutine programs, and the selection is performed by the microcomputer 25 by reading the selection of the mode switch 80 at regular intervals.

In addition, according to the present invention, it is also possible to further include a lantern 35 in a portion of the LED 10 to move downward. By installing the lantern 35 detachably on the lower part of the light rod handle less movement, when clearing the instructions and instructions at the time of inspection, and clear the ID card or writing, there is no inconvenience to move to the street light. Rather than being located at the tip of the display unit where the detection means 30 is located, it is located below the handle to secure a copper wire for identifying the identification card, thereby increasing convenience.

3 is a schematic diagram showing a detection means according to a first embodiment of the present invention.

As a first embodiment, the detection means 30 has a first angle sensor 41 and a second angle sensor 42 which are arranged to be inclined opposite to the same angle with respect to the array line of the LED 10. The angle sensor 41, 42 for switching the on / off signal is provided on both sides at the tip of the light rod. The angle sensors 41 and 42 are arranged in a symmetrical state in which the directions in which the ground portions are located are opposite to each other. For example, when the + (or on) direction of the first angle sensor 41 located on the right side of the center line where the LED 10 is disposed is close to the center line, the second angle sensor 42 located on the opposite left side is- Make sure the (or off) direction is close to the centerline. As a result, when moving to the right or left side of the light rod or moving down from the top, the microcomputer 25 can determine the forward image display and the reverse image display by the +,-(or on, off) signals of the sensors 41 and 42. have.

How to implement an asymmetric image using two angle sensors (41, 42) and detect the time that both sensors are + (or on) and find out the speed that is moved from top to bottom or left to right Can be. The microcomputer 25 calculates the speed using the input of the sensor input through the input unit 21 and the time by its own timer, and then outputs an output that changes the blinking timing of the LED 10 to a value proportional to the corresponding speed. 22).

More specifically, the controller 20 detects the one-stroke operation period in both angle sensors 41 and 42, calculates it as a speed, substitutes the calculated speed into the value of the input program, and substitutes the reference speed according to the program that is substituted. The lighting time of the LED 10 is changed to a changed value in comparison with. The value at the time of moving down from the top of the light rod is applied equally to the case of moving from the top to the bottom, and the value at the time of moving from the left to the right is equally applied when moving from the right to the left. Of course, such control is to reduce the burden of the microcomputer 25 to respond quickly, and the control can be subdivided into shorter cycles as the processing speed of the microcomputer 25 is improved.

4 is a schematic view showing a detection means according to a second embodiment of the present invention.

As described above with respect to the method using the angle sensors 41 and 42 and calculating the speed according to the operation time as shown in FIG. 3, only a still image can be implemented and the number of letters that can be implemented is limited. Since the speed or angle of shaking according to a person is not constant, it is necessary to detect more precise data that can reflect the accurate image at a constant position at all times. In this way, more accurate and bright images can be superimposed on the same location in space with less power, and moreover, it is possible to realize flowing animation movements rather than simply fixed afterimages.

As a second embodiment, the detection means 30 detects a cylinder 51 having an upper and lower opening, an impeller 52 rotatably received in the cylinder 51, and a rotation speed / direction of the impeller 52. The encoder 55 is provided. The cylinder 51 is installed in the direction of the trajectory where the inflow of air is smooth from the tip of the light rod. The pinwheel-type impeller 52 is mounted in the middle of the cylinder 51 together with the encoder 55. When air flows into the cylinder 51 when shaking the light rod, the impeller 52 rotates and a signal is generated from the encoder 55. The encoder 55 may use a kind of generator that does not require an external power source, and the sine plate signal is counted by the microcomputer 25 via the A / D converter of the input unit 21 to determine the period. Used as The microcomputer 25 checks the input unit 21 in real time to increase the moving speed of the light rod, thereby increasing the lighting speed of the LED 10 and lowering the lighting speed when the microcomputer 25 increases.

In this way, since the response speed of the system is quick and the signal is generated without power consumption, accurate image retention is possible and it is also very advantageous for the implementation of moving characters and animations.

5 is a schematic view showing a detection means according to a third embodiment of the present invention.

To realize the moving image after moving in space, check the speed of the moving light rod in real time and input it to a program that processes it. The hardware determines whether the speed increases or decreases according to the input value, and increases or decreases the speed of lighting through this. In the process, the role of hardware such as the detection means 30 becomes more important.

As a third embodiment, the detection means 30 is sealed to a conductive cylinder 61 into which power is supplied, a ground plate 62 disposed on one surface of the conductive cylinder 61, and a conductive cylinder 61. And spheres 65 in contact and moving on ground plate 62. The conductive cylinder 61 is installed at the same position as the cylinder 51 described above, and is sealed to prevent the flow of wind. Power is supplied from the inner space to the side or the top surface, and a plurality of ground plates 62 are disposed at regular intervals on the bottom surface. The sphere 65 is formed of a metal having a certain weight, and flows in contact with at least one surface of the conductive container 61 and the ground plate 62.

Accordingly, the speed can be detected by calculating the time for which the sphere 65 is grounded for each ground plate 62. The detected speed is continuously updated in real time by the controller 20 as mentioned above, and when the speed at which the light rod moves up and down or left and right increases, the lighting speed of the LED 10 is increased and the lighting speed is lowered when the speed is lowered. .

At this time, it is preferable that a tact switch 64 for detecting a direction is provided at one end of both ends of the conductive cylinder 61 for the afterimage image to be realized up and down. The tact switch 64 generates and sends a signal to the controller 20 when the sphere 65 contacts.

6 is a schematic view showing a detection means according to a fourth embodiment of the present invention.

As a fourth embodiment, the detecting means 30 includes a ground plate 72 arranged in a circumferential manner, a conducting rod 74 rotatably installed on the ground plate 72, and the conducting rod 74. It is coupled to the other end of the contact plate 75 to move on the ground plate (72). This is a configuration incorporating a kind of metronome principle and corresponds to a modification of FIG. One end of the lead rod 74 is rotatably supported at the same position as the center of the radius of curvature of the ground plate 72. On the other end of the conductive rod 74, which is a conductor, a ground plate 72, which is also a conductor, is fixed. The operation of varying the speed at which the contactor 75 passes through the ground plate 72 according to the speed of moving the light rod is the same as that of FIG. 5.

In the related art, a moving afterimage can be displayed by imposing a device capable of obtaining a constant rotation and vibration, such as a motor. However, according to the present invention, it is possible to implement with little power.

Meanwhile, the mode switch 80 of the present invention may further include a function selection for simply blinking the LED 10 instead of displaying a letter. This function is, of course, performed by the microcomputer 25 and its execution algorithm is mounted in the memory 24.

It is apparent to those skilled in the art that the present invention is not limited to the embodiments described, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.

According to the above configuration and operation, the present invention has the effect that the image display by the afterimage effect is accurate and the operation reliability can be maintained regardless of the size or shape of the trajectory of the user moving the light rod.
