The present invention relates to a monochromatic and multicolor LED module having a structure that can be used for a monochromatic LED module and a multicolor LED module, and more particularly, a monochromatic LED module and four power lines are drawn in with two power lines drawn out. It relates to a monochrome and multi-color LED module having a case that can be commonly used in the three-color LED module to be emitted.

As shown in FIG. 1, the conventional LED module 10 is inserted into a case 12 of a rectangular body having a through hole 11 at lower left and right sides thereof, and inserted into a through hole 11 of the case 12. A power supply line 13 for supplying a voltage, a printed circuit board 16 having a plurality of LED elements 14 mounted on an upper surface thereof and having a plurality of fastening holes 15 at a position through which the power supply line 13 passes; The screw 17 is fastened to the fastening hole 15 of the printed circuit board 16 and connected to the power line 13.

In the conventional LED module 10 configured as described above, the power supply line 13 is positioned below the printed circuit board 16 on which the plurality of LED elements 14 are mounted. The screw 17 is inserted through the formed fastening hole 15 to connect the printed circuit board 16 and the power line 13, and then the power line 13 is connected to the inside of the case 12. The printed circuit board 16 is inserted, and then the case 12 is filled with a resin (silicon) 18 so as not to cover the LED element 14 of the printed circuit board 16 to be molded.

When the LED module 10 is manufactured for a single color LED, two power lines are drawn into and drawn out of the case 12, but when LEDs emitting different colors are installed, four power lines are placed in the case 12. Since it is to be drawn in and withdrawn, there is a problem that the manufacturing cost is increased because each case should be provided according to the monochromatic LED and the multicolor LED.

The present invention is to solve such a problem, the problem of the present invention is to provide a LED module that can be used in common for the multi-color module that the two power line is drawn in and out and the four power line is drawn out It is to.

The solution for solving the above problem is a LED having a printed circuit board in which an LED and an electric circuit for lighting the LED are installed in a case having a bottom surface and a plurality of sidewalls formed vertically from an outer circumferential surface of the bottom surface. In the module, the first sidewall and the second sidewall opposite to the first sidewall are opened upwardly, and grooves each having four curved grooves formed of downward curved grooves on the bottom thereof are formed to face each other, and each of the grooves The bushing is inserted, but when the four power wires are drawn in and out of the case, the first bushing having four curved grooves formed of upward curved grooves is inserted into the bottom, and the two power wires are drawn in and out of the case. At the time, the curved projections projecting downward on both sides of the bottom are formed, and the curved groove consisting of the upward curved groove is formed at the center of the bottom. The second formed bushing is fitted.

In the present invention, the synthetic resin of the transparent material is laminated on the printed circuit board.

In addition, in the present invention, the color of the upper surface of the printed circuit board and the color of the LED lighting light is the same.

According to the present invention having the above-described problems and solutions, the case for four lead-out power lines when the LED is installed in a multi-color and the case for two lead-out power lines when the LED is installed in a single color separately Since there is no need to manufacture, the case can be manufactured at low cost.

In addition, since the synthetic resin to be molded in the present invention as a transparent material, since the color of the LED light and the color of the printed circuit board are used in the same way, the shadow portion generated by the LED module can be removed.

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

Figure 2 is an exploded perspective view when four power cords are drawn in and out of the case in an embodiment of the present invention, Figure 3 is an exploded perspective view when two power cords are drawn out in the case in an embodiment of the present invention, FIG. 4 is a front view when four power lines are inserted into a case in one embodiment of the present invention, and FIG. 5 is a front view when two power lines are inserted into a case in an embodiment of the present invention.

The case 20 is composed of four side walls 23, 25, 27, and 29 formed perpendicular to the bottom surface 21 and the outer circumferential surface of the bottom surface 21. The center of the side wall 23 has a substantially rectangular shape with an upper portion open, and grooves formed with four curved grooves 26 formed as curved grooves downward on the bottom face are formed at the center thereof, respectively. In addition, the same shape as that of the groove of the side wall 23 is formed also in the side wall 25 which opposes the side wall 23. As shown in FIG. In addition, the bottom surface 21 is provided with a row groove 22 connected between the side wall 23 and the grooves formed in the side wall 25.

In addition, when four power wires 80 are drawn in and out of the case 20 in order to light up multi-colored LEDs in the grooves of the side walls 23 and 25, four grooves on the bottom surface thereof are shown in FIGS. 2 and 4. When the bushings 60 and 60 'having curved grooves upwards are fitted, and two power lines 80 are drawn in and out of the case 20 to light up a monochromatic LED, as shown in FIGS. Likewise, curved bottom protrusions protruding downwardly are formed at both ends of the bottom, and bushings 70 and 70 'formed with two curved grooves upwardly in the center thereof are fitted.

Both sides forming the grooves are provided with fitting protrusions 24 in the vertical direction, and both sides of the bushings 60, 60 ', 70, and 70' are also inserted into the grooves when they are inserted into the grooves ( Insertion grooves 61 and 71 into which 24 can be fitted are formed, respectively.

As shown in FIGS. 2 and 4, when four power lines 80 are drawn, the four power grooves 80 are formed on the bottom surface of the grooves of the side walls 23 and 25. It is arranged to pass through the upper surface and the row groove 22, the bushing 60 is fitted to the side wall 23, the bushing 60 'is fitted to the side wall 25, in this state bushing 60, (60') It is fixed between the curved groove 62 and the curved groove 26 of the groove.

In addition, when two power lines 80 are drawn in, the power lines 80 may have two curved grooves at the center of the curved grooves 26 formed on the bottom of the grooves, as shown in FIGS. 3 and 5. 26, and the bushings 70 and 70 'are fitted into the grooves. At this time, a curved groove 72 is formed at a portion of the bottom portion of the bushings 70 and 70 'through which the wire passes, and a curved surface at a portion of the bottom portion of the bushings 70 and 70' does not pass. Protruding portion 73 is formed so as to be in contact with the curved groove 26 adjacent to the side of the bottom of the groove.

As shown in FIGS. 4 and 5, the side wall of the case 20 is sealed even when two power lines are drawn in and out of the case and four power lines 80 are drawn in and out of the case using different bushings. do.

As such, when the power line 80 is installed between the bottom of the groove and the bushing, the printed circuit board 42 on which the LED 41 is protruded upward is installed on the bottom surface 21, and the row groove 22 is formed. It is connected between the power supply line 80 and the printed circuit board 42 passing through a pin or the like not shown to supply power to the LED 41. When the printed circuit board 42 is installed in the case 20, a transparent resin is laminated on the upper surface of the printed circuit board 42, but the upper surface of the LED 41 is exposed to protect the printed circuit board 42.
