Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a perspective view showing a schematic structure of a wire-mounted single light source light emitting device according to a first embodiment of the present invention, Figure 2 is a schematic configuration of a lattice display device using the wire-mounted single light source light emitting device of FIG. It is also.

The wire-mounted single-light source light emitting element 3 according to the first embodiment of the present invention is electrically connected to the horizontal wire 2, and has a first electric wire that provides a space in which the horizontal wire 2 can be mounted and soldered. A first pad 12 having a connection groove 12a formed therein, and a second wire connection groove that is electrically connected to the vertical wire 1 to provide a space where the vertical wire 1 can be mounted and soldered ( 2nd pad 13 in which 13a is formed, the light emitting diode 11 electrically connected with the 1st pad 12, and the 2nd pad 13, the 1st pad 12, and the 2nd pad 13 ) And a transparent insulator 14 electrically separating the liver.

The + terminal of the LED 11 is connected to the first pad 12 and the − terminal is connected to the second pad 13 so that the vertical wire 1 and the horizontal wire 2 are respectively the first and second pads 12. , 13), voltages applied to the vertical wire 1 and the horizontal wire 2 are applied to the + terminal and the-terminal of the LED 11.

The light emitting device 3 is mounted on a portion where a plurality of vertical wires 1 and a plurality of horizontal wires 2 installed in the vertical direction intersect with the vertical wires 1 as shown in FIG. Configure The vertical wires 1 and the horizontal wires 2 are electrically separated from each other by the transparent insulator 14 and do not conduct with each other.

3 is a perspective view showing a schematic structure of a wire-mounted multi-light source light emitting device according to a second embodiment of the present invention, FIG. 4 is a circuit diagram showing an internal configuration of the wire-mounted multi-light source light emitting device of FIG. 4 illustrates an example of a driving signal applied to the LED controller of FIG. 4.

In the second embodiment, a plurality of vertical wires 1, a plurality of horizontal wires 2 installed in a vertical direction with the vertical wires 1, and a portion where the vertical wires 1 and the horizontal wires 2 intersect. The basic configuration including a plurality of light emitting portions 3 to be connected is the same as in the first embodiment.

The second embodiment has a structure in which three diodes of the R diode 21, the B diode 22, and the G diode 23 are included in one light emitting element 3, and the light emitting part for light emission control of the three diodes is included. The LED controller 24 is mounted in (3).

Looking at the circuit for driving three diodes, as shown in the circuit diagram of Figure 4, the LED controller 24 is connected between the vertical wire (1) and the horizontal wire (2), R diode 21, B diode 22, The anode of the G diode 23 is connected to the LED controller 24 and the cathode of each diode 21 to 23 is connected to the horizontal wire 2.

The voltage or signal applied to the horizontal wire 2 acts as a signal for selecting the light emitting portions of the horizontal line as the line selection signal. That is, when the horizontal wire 2 is grounded, it becomes a condition that each light emitting diode 21 to 23 can be conducted. Therefore, the corresponding line is selected, and when the horizontal wire 2 is open or Vcc is applied, each light emitting diode ( 21 ~ 23) is a condition that can not be conducted, the corresponding line is in a deactivated state.

The voltage or signal applied to the vertical wire 1 is a driving signal for driving the light emitting diode, and the light emitting parts 3 present on the selected line sequentially emit light according to the driving signal applied through the vertical wire 1. In the light emitting unit 3, three light emitting diodes emit light simultaneously or sequentially based on a driving signal.

Usually, open or Vcc is applied to the horizontal wire 2, and Vcc is applied to the vertical wire 1. In this state, no current flows and the LED controller 24 does not operate. When ground is applied to one horizontal wire 2 to display a screen, the LED controller 24 inside all light emitting elements 3 connected to the horizontal wire 2 starts to receive power.

Subsequently, as shown in FIG. 5, the voltage signal applied to the vertical wire is a driving signal for driving the light emitting diode and analyzes the signal in the logic 27 inside the LED controller 24 to blink each LED.

Since the operation of the logic 27 may be stopped while the driving signal for driving the LED controller 24 on the vertical wire 1 is ground, parallel to the logic 27 inside the LED controller 24 as shown in FIG. 4. By connecting the diode 25 and the capacitor 26, it is preferable to maintain the power of the logic 27 by using the auxiliary power charged in the capacitor 26. The diode 25 is for preventing reverse current from the capacitor 26 to the vertical wire 1 when the capacitor 26 is used as an auxiliary power source.

As shown in FIG. 5, the driving signal applied to the logic 27 may be a PWM signal, and one LED may be driven and controlled per cycle of the PWM signal. That is, the R diode 21 conducts while high in the first period of the PWM signal, the G diode 22 conducts during the High of the second period, and the B diode 23 conducts during the High of the third period and the pulse width. The brightness of the light may be adjusted by using and the operation may be repeatedly performed while the driving signal is applied.

As described above, when a single light emitting diode or an RGB light emitting diode is installed on each side of the polyhedron, the LED controller 24 sequentially controls several light sources installed on the basis of the driving signal.

6 is a view for explaining the necessity of the light directivity in the present invention, Figure 7 is a view showing the configuration of a lens and a reflector for the light directivity in the first embodiment.

If the structure that emits light to both front and back, such as the wire-mounted light emitting device according to the first embodiment, the mirror image is visible when viewed from the rear. In order to prevent such inconvenience, as shown in FIG. 7, the lens 15 and the reflecting plate 16 may be installed so that light is sent only in a desired direction.

In addition, three-dimensional objects can be expressed by overlapping display panels with transparency. 6 illustrates the reason why light direction of the light source element is necessary. If the light spreads in all directions, as in A), a hidden line is visible that should not be visible. In order to prevent such a rear view, the lens 15 and the reflector 16 should be installed as shown in FIG.

The front surface of the light emitting diode 11 is provided with a lens 15 for directing the light emitted from the light emitting diode 11, the at least one of the rear surface of the light emitting diode 11 or the outer peripheral surface of the lens 15 (reflective plate ( 16) is preferably installed.

In FIG. 7, the lens 15 is installed on the front surface of the light emitting diode 11, and silver is plated on the outer circumferential surface of the lens 15 so that light emitted from the light emitting diode 11 is emitted only in front of the lens 15. One case is shown.
