In this case, in order to properly utilize the plurality of projection glasses, it is necessary to determine the initial position and how many projection glasses should be located at which position.

1 is a view showing the appearance of a logo light according to an embodiment of the present invention. Referring to FIG. 1, a logo light 1000 according to an embodiment of the present invention is manufactured to receive power from the outside, and includes a lens unit 1100 composed of at least one lens, and a heat dissipation unit 1200 for cooling. And, between the lens unit 1100 and the heat dissipation unit 1200, it has a body (A) in which various electronic devices and mechanical devices are embedded.

Here, the logo light driving apparatus 100 according to an embodiment of the present invention is mounted on the body A.

Hereinafter, a logo light driving apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

2 is a block diagram of a logo light driving apparatus according to an embodiment of the present invention, and FIG. 3 is a diagram showing a configuration using a magnetic field sensor in a logo light driving apparatus according to an embodiment of the present invention. And Figure 4 is a view showing a configuration using a light amount sensor in the driving device of the logo light according to an embodiment of the present invention.

Referring to FIG. 2, the driving apparatus 100 of a logo light according to an embodiment of the present invention includes a rotating plate 110, a driving unit 120, a light irradiation unit 130, an initial position grasping unit 140, and a light amount sensor 150. ) And an operation control unit 160. Here, a user input unit such as a button or switch for receiving a user's input and a memory (storage unit) for storing information have been omitted since they are a typical configuration.

The rotating plate 110 includes a circular body 111 and a plurality of assembly holes 112 formed in the body 111. The assembly hole 112 is formed to penetrate the body 111, and the projection glass 10 is mounted (assembled). The number of assembly holes 112 formed in the rotating plate 110 is two or more, and the maximum number is determined according to the diameter size of the through holes 1301 formed in the transmission plate 1300.

The drive unit 120 is mechanically connected to the rotary plate 110 and generates power to drive the rotary plate 110 to rotate the rotary plate 110 in a set direction. Here, the driving unit 120 may be composed of, for example, a motor, a gear, and a shaft.

The light irradiation unit 130 is fixedly installed to irradiate light to the rotating plate 110. For example, the light irradiation unit 130 transmits the irradiated light through one assembly hole 112 formed in the rotating plate 110, and the transmitted light transmits through the through hole 1301 formed in the transmission plate 1300, so that the lens unit ( 1100). The light irradiation unit 130 may be configured as an LED device, for example.

The initial position grasping unit 140 grasps the initial position of the rotating plate 110. The initial position of the rotating plate 110 is a position in which one set assembly hole 112 (hereinafter referred to as'initial position assembly hole') is on the same axis as the through hole 1301 of the transmission plate 1300. The initial position assembly hole 112 for determining the initial position transmits light first by the light irradiation unit 130 during operation for an effect such as security or advertisement.

Here, each of the plurality of assembly holes 112 formed on the rotating plate 110 has its position determined based on the initial position assembly hole, and the position of each assembly hole is stored in a memory. For example, when the rotating plate 110 rotates in a clockwise direction, the first assembly hole located in the clockwise direction with respect to the initial position assembly hole is separated by an interval A (or rotation angle, etc.) from the initial position assembly hole position, and the initial position The second assembler, located clockwise from the assembler, is spaced B intervals (or rotation angle, etc.) from the position of the first assembler, and the third assembler is located clockwise from the initial position of the assembler. C is spaced apart (or rotation angle, etc.)

Here, it is preferable that the interval A, the interval B and the interval C are the same.

As shown in (b) of FIG. 3, the initial position determination unit 140 senses a change in the magnetic field by the magnetic protrusions 141 and the magnetic protrusions 141 with magnetism, and a voltage corresponding to the detected magnetic field change Alternatively, it is configured to include a magnetic field sensor 142 outputting a current. At this time, the magnetic protrusion 141 is installed on the rotating plate 110, and is installed at a position such that it becomes an initial position when it is closest to the magnetic field sensor 142. 3 shows that the magnetic protrusion 141 is installed close to the initial position assembly hole 112, but when the position of the magnetic field sensor 142 is changed, the magnetic protrusion 141 is The mounting position will change according to the position.

The light amount sensor 150 is located between the transmission plate 1300 and the rotating plate 110, and receives the light irradiated by the light irradiation unit 130 through the assembly hole 112, and senses the amount of received light. Here, when the light amount sensor 150 is positioned on the optical axis of the light irradiated by the light irradiation unit 130, the image of the light amount sensor 150 is displayed on the image image output through the lens unit 1100. Therefore, it is preferable that the light amount sensor 150 is installed very close to the through hole 1301 of the transmission plate 1300.

As another example, the light amount sensor 150 may be installed on one surface of the rotating plate 110 facing the transmission plate 1300. In this case, it is preferable that a reflecting plate (not shown) that reflects the light transmitted through the rotating plate 110 is installed on one surface of the transmission plate 1300 facing the rotating plate 110, and the reflecting plate is It should be prevented from entering the assembly hole 112 of the rotating plate 110.

The operation control unit 160 controls the operation of the driving unit 120, the light irradiation unit 130, the initial position detection unit 140, and the light amount sensor 160 according to a command input from the user input unit, and is mounted on the rotating plate 110. The image of the projection glass is output through the lens unit 1100. At this time, the operation control unit 160 operates in a setup mode and an operation mode.

The setup mode is set when the driving device 100 is powered on or off, and automatically switches to the operating mode when the setup operation is completed. The operation of the set-up mode operates the light irradiation unit 130, the initial position determination unit 140, and the light amount sensor 150 when the driving device 100 is powered on or off, and the output of the initial position determination unit 140 The initial position is determined through, and the output of the light amount sensor 150 is compared with the set reference amount of light to determine whether the projection glass 10 is mounted, and accordingly, the number and position of the projection glass mounted on the rotating plate 110 are identified. And store it in memory.

The operation mode is an operation mode generally performed by a logo light in a state in which the initial position detection unit 140 and the light amount sensor 150 are deactivated, and the image of the projection glass mounted on the rotating plate 110 is transferred to the lens unit 1100. It is a mode to output through. In the case where the number of projection glasses mounted on the rotating plate 110 in the operation mode is two or more, the user can arbitrarily set and change the illumination time for illuminating one projection glass.

For example, if the user sets the illumination time to 5 seconds, the operation control unit 160 allows the light of the light irradiation unit 130 to be projected on one projection glass for 5 seconds, and then positions the next projection glass to the light irradiation unit 130. Let the light project again for 5 seconds. If the user sets the illumination time to 10 seconds, the operation control unit 160 allows the light of the light irradiation unit 130 to be projected on one projection glass for 10 seconds, and then positions the next projection glass to the light irradiation unit 130. Let the light project again for 10 seconds.

In addition, the operation control unit 160 has a continuous image mode function, and when the continuous image mode is set, the rotating plate 110 is rotated at the calculated rotational speed so that a moving image is outputted by the plurality of assembly holes 112. Here, the rotational speed is calculated by the motion control unit 160, and is calculated using the number and position of the projection glasses. The motion control unit 160 makes the rotational speed faster as the number of mounted projection glasses 10 decreases, and slows the rotational speed as the number of mounted projection glasses 10 increases.

Therefore, the rotational speed is the slowest when the projection glass 10 is mounted on all assembly holes 112 of the rotating plate 110, and the rotational speed is the most when the two projection glasses 10 are mounted on the rotating plate 110. fast. As a result, the fastest rotational speed and the slowest rotational speed according to the number of assembly holes 112 have already been set.

Of course, the continuous image mode can be set when two or more assembly holes 112 are installed on the rotating plate 110.

Hereinafter, an operation of the logo light driving apparatus according to an embodiment of the present invention will be described with reference to FIGS. 5 and 6.

5 is a diagram showing an operation of the logo light driving apparatus according to the first embodiment of the present invention, and is an operation in a setup mode. Referring to FIG. 5, when a user presses a power switch or a scan switch attached to the logo light to turn the power off state to the power on state, the operation control unit 160 receives a scan operation start signal (S501). Here, the scan operation start signal may be automatically executed when the user finishes the operation of assembling the projection glass on the rotating plate 110.

When the scan operation start signal is received, the operation control unit 160 activates the magnetic field sensor 142 (S502) and operates the driving unit 120 to rotate the rotary plate 110 (S303).

When the rotating plate 110 is driven to rotate, the magnetic protrusion 141 away from the magnetic field sensor 142 approaches the magnetic field sensor 142, and the magnetic protrusion 141 detects the magnetic field sensor 142 at the closest point. A signal is provided to the operation control unit 160.

Accordingly, when receiving the detection signal of the magnetic field sensor 142 (S504), the operation control unit 160 stops the rotation of the rotating plate 110, identifies and sets the stopped current position as an initial position, and sets the magnetic field sensor 142 ) Is deactivated (S505).

Then, the operation control unit 160 activates the light irradiation unit 130 and the light amount sensor 150 (S506), and the assembly hole in a position parallel to the through hole 1301 of the transmission plate 1300 is compared with the initial position assembly hole N It is determined whether it is the second (S507). Here, the Nth means the last. For example, if the number of assembling holes of the rotating plate 110 is 6, it is the sixth assembling hole in a position parallel to the through hole 1301 based on the position of the initial position assembling hole.

Since the current is in the initial position, the operation control unit 160 determines that it is not the N-th assembly hole (S507). Accordingly, the operation control unit 160 measures the amount of light with a signal received from the light amount sensor 150 (S508), and compares the measured amount of light with a set amount of light (set amount of light) (S509).

Here, the set amount of light is set as the first amount of light measured when the projection glass 10 is not mounted in the assembly hole 112 in the state where light is irradiated from the light irradiation unit 130 or a second amount of light that is slightly smaller than the first amount of light. . At this time, the set amount of light is set to be larger than the largest amount of light measured when the projection glass 10 is mounted on the assembly hole 112.

The operation control unit 160 determines that the assembling hole 112 is not installed if the measured light amount is greater than or equal to the set light amount, and determines that the assembling hole 112 is installed if the measured light amount is less than the set light amount (S510). Through this determination process (S510), the operation control unit 160 can check whether the projection glass 10 is mounted in the initial position assembly hole.

When the determination of whether to mount the projection glass for the initial position assembly hole is completed, the operation control unit 160 rotates the rotating plate 110 by a set rotation amount so that the next assembly hole, that is, the second assembly hole, faces the through hole 1301 ( S511).

Here, the information on the set rotation amount is information previously stored in the memory.

The operation control unit 160 performs processes S507 to S511 to determine whether or not the projection glass is mounted in the second assembly hole, and stores the determined information in the memory. In addition, the operation control unit 160 repeatedly performs steps S507 to S511 up to the (N-1)-th.

When the N-th assembly hole is located, the operation control unit 160 checks whether the projection glass is mounted in the N-th assembly hole by performing the processes S508 to S510 (S512), and returns the rotating plate 110 to the initial position (S513). .

When the rotating plate 110 is returned to the initial position in this way, the driving device 100 drives the rotating plate 110 according to the set mode so that a desired image is output through the lens unit 1100.

Meanwhile, according to another embodiment of the present invention, when the user turns off the power, the operation control unit 160 performs steps S501 to S505 and turns off the power.

6 is a diagram showing an operation of a logo light driving apparatus according to a second exemplary embodiment of the present invention, and illustrates a case in which the logo light driving apparatus according to an exemplary embodiment of the present invention has a continuous image mode function.

Referring to FIG. 6, when the operation control unit 160 receives a scan operation start signal through a user input unit (not shown) (S601), the operation control unit 160 performs the processes S502 to S513 of FIG. 5 to be mounted on the rotating plate 110. The number of projection glasses and the mounting position are determined (S602).

Then, the motion control unit 160 calculates the rotational speed in the continuous image mode in consideration of the number of projection glasses and the mounting position, and stores the calculated rotational speed (S603). At this time, the rotation speed for the case of the maximum projection glass and the case of two projection glasses is set in the memory. Here, when the number of projection glasses is the maximum, the first rotational speed with the slowest speed is set, and when the number of projection glasses is 2, the second rotational speed with the fastest speed is set. Of course, the rotation speed for all cases corresponding to the number of projection glasses and the mounting position can be stored in memory as a table value.

When the number of assembly holes 112 of the rotating plate 110 is 6, the calculation of the rotation speed is as follows.

Considering only the number of projection glasses, the motion control unit 160 sets the third rotational speed by subtracting the first deceleration amount set from the second rotational speed when there are three projection glasses. 3 Set the fourth rotational speed by subtracting the first deceleration amount from the rotational speed. In the case of five projection glasses, the fifth rotational speed is set by subtracting the first deceleration amount from the fourth rotational speed. The fifth rotation speed is a rotation speed that is faster than the first rotation speed, and may be a value obtained by adding the first rotation speed to the first rotation speed.

Considering the mounting position in the number of projection glasses, the motion control unit 160 calculates and sets the rotational speed to be faster when the projection glasses are separated from each other than when the projection glasses are adjacent to each other. For example, if there are three projection glasses and are adjacent to each other, the motion control unit 160 sets the third rotation speed by subtracting the first deceleration amount set from the second rotation speed, and the projection glasses are three and are spaced apart from each other. If so, the first acceleration amount is added to the third rotational speed to calculate a 3-1 rotational speed faster than the third rotational speed. Of course, if there are three tungyeong glasses and two are adjacent and one is separated, the 3-2 rotation speed is faster than the third rotation speed and slower than the 3-1 rotation speed.

When the calculation and storage of the rotational speed is completed, the operation control unit 160 sets the continuous image mode (S604), grasps the set rotational speed (S605), and rotates the rotation plate 110 at the set rotational speed. The video generated by the projection glasses mounted through the unit 1100 is output (S606).

The above description is intended to provide exemplary configurations and operations for implementing the present invention. The technical idea of the present invention will include not only the embodiments described above, but also implementations that can be obtained by simply changing or modifying the above embodiments. In addition, the technical idea of the present invention will also include implementations that can be achieved by easily changing or modifying the embodiments described above.
