The present invention relates to an LED (LED) bar that can be cut and used, and more specifically, it is possible to emit light by connecting any polarity to each terminal drawn out from the LED (LED) bar used for decorative purposes, as well as LED (LED) ) The bar is cut to a certain length so that it can be used.

As is well known, LED bars are manufactured in the form of bars by arranging a plurality of LEDs side by side, and are mainly used for decoration.

In general, the LED (LED) bar is a number of LEDs form a set, these sets are fixed side by side on the substrate is connected in parallel for each set, each set is made of one chip resistor, The terminal of (+) (-) is drawn out at one end of the terminal, and this general LED bar needs to be applied with the correct polarity. Otherwise, the LED may be damaged. In the case where the entire LED bar having a certain length cannot be used due to site conditions, it is impossible to fill all of the indispensable LED bars, which may have a disadvantage of deterioration of decoration.

In addition, the chip resistors, which are provided one by one for a certain number of sets of LEDs, are generally formed in a rectangular shape, and the length of the chip resistors is disposed in the length direction of the LED bar, so that the LED bar is handled when the LED bar is handled or installed. When it is bent, it is separated from the substrate, which causes unstable light emission of the LED (LED) due to poor contact, or causes the LED (LED) not to emit light.

The present invention has been proposed in view of such a point, and the LED can emit light even when the power applied to the LED bar is applied regardless of its polarity, and the LED bar can be cut to a certain length according to the site conditions. It can be used for convenience, and by installing the chip resistor in the direction perpendicular to the length of the LED bar, the LED bar can be cut and used without fear of short circuit even if the LED bar is bent. LED bar is to provide.

Hereinafter, the present invention will be described in detail with reference to the embodiments presented.

1 is a perspective view of the LED (LED) bar according to the present invention, Figure 2 is a detailed view of the cutting portion of the LED (LED) bar according to the present invention.

As shown in the LED bar (100) to which the present invention is applied, a certain number of LEDs 111 form one set 110, and the LED sets 110 are arranged side by side on the substrate 120. Fixed and connected in parallel, each LED set 110 is provided with a chip resistor 130 of a rectangular shape, one for each LED set 110, in the present design, the LED (LED) set 110 or other LEDs adjacent to one or two units The bridge rectifier circuit 140 is electrically connected between the (LED) set 110 so that each LED 111 can always emit light regardless of the polarity of the power applied to each LED 111. On the front surface of the bridge rectifier circuit of the substrate 120, a "V" -shaped groove 121 is formed on the cross section to cut this portion and use it. In the drawing, one LED set 110 is composed of six LEDs 111 and the bridge rectifier circuit 140 is connected to each of the two LED sets 110 as an example.

At this time, the back surface of the "V" groove 121 of the substrate 120, based on the position of the "V" groove 121, on the opposite side of the bridge rectifier circuit 140, each of the two LEDs 111 so as to be energized The terminal connection hole 122 is formed, and two connector connection holes 123 are formed on the bridge rectifier circuit 140 side so as to be energized with each of the LEDs 111.

In addition, the rectangular chip resistor 130 is provided in a direction in which the longitudinal direction thereof is perpendicular to the longitudinal direction of the substrate 120.

And, the copper foil is formed on the back of the mounting position of the LED 111 of the substrate 120 so that each of the LEDs 111 can be connected in parallel so as to conduct electricity, which is a general technique, so the copper foil is omitted in the present invention.

In the drawing, reference numeral 150 denotes a terminal, and reference numeral 160 denotes a connector.

The operation of the LED bar according to the present invention configured as described above will be described with reference to FIGS. 3 and 4.

First, since the LED bar 100 according to the present invention is connected to each of the LED set 110 two bridge rectifier circuit 140 therebetween, the LED bar as shown in FIG. No matter what polarity the power is applied to each terminal 150 connected to one end of the 100, it is full-wave rectified by each bridge rectifier circuit 140 so that each LED 111 is irrespective of the polarity of the power source. In this case, the light emission is made, and thus, the operator installing the LED bar 100 does not have to worry about the polarity of the power applied to the LED 111, thereby making it easier to use.

In addition, since the "V" groove 121 is formed on the front surface of the bridge rectifier circuit front surface of the substrate 120, when the LED bar 100 requires only a small amount of field conditions, the "V" groove 121 is formed. By bending both sides downward based on the part, the LED bar 100 can be easily cut. In this case, the cut LED bar 100 has at least one bridge rectifier circuit 140. All LEDs 111 may emit light regardless of the polarity of the applied power.

At this time, the back surface of the "V" groove 121 of the substrate 120, based on the position of the "V" groove 121, on the opposite side of the bridge rectifier circuit 140, each of the two LEDs 111 so as to be energized Since the terminal connection hole 122 is formed, the terminal 150 is inserted into each terminal connection hole 122 at the LED bar 100 itself or the cut pieces of the LED bar 100 to supply power at any time. LED connector bar is formed on the opposite side of the terminal connection hole 122 of the substrate 120, that is, two connector connection holes 123 are formed on the side of the bridge rectifier circuit 140 so as to conduct electricity with each LED 111. When connecting the (100) to each other, or to connect the LED bar (100) and the pieces of the cut (LED) bar (100) to each other between the terminal connector 122 and the connector connector 123 between the connector 160 ) Can be connected to each other, and in this way all LED (LED) bar 100 connected state without the need to apply power to each LED (100) Stand when the power to the one LED (LED) bar the terminal 150 drawn out of the 100 is applied is used, because it becomes more convenient.

Of course, in this case, since each of the LEDs 111 may emit light regardless of the polarity of the power supply by the bridge rectifier circuit 140, all of the LED bars 100 connected to each other as shown in FIG. 4 are connected in the positive direction. In addition, even if one of the LED bar (100) connected to each other connected in the reverse direction, there is no problem in its use.

On the other hand, the rectangular chip resistor 130 is provided for each of the LED set 110 consisting of six LEDs 111 is installed in a direction perpendicular to the longitudinal direction of the substrate 120 LED (LED) Even when the substrate 120 is slightly bent at the time of handling or installing the bar 100, the chip resistor 130 does not fall from the substrate, thereby preventing contact defects.

In addition, the lower surface of each LED 111 installation position of the substrate 120 may be configured to increase the luminance of the light generated from the LED 111 by applying a metal plating such as nickel plating, such a technique of the present invention It is said to belong to a category.

As described above, in the present invention, since the bridge rectifier circuit is energized by one or two sets of LED sets, the LEDs can always emit light regardless of the polarity of the power applied to each LED. In particular, the LED bar can be cut to a certain length so that it can be actively coped with on-site conditions, and the chip resistance is installed in a direction perpendicular to the length of the board, so that even if the board is slightly bent, There is no fear that the chip resistance will fall from the substrate, so that the life can be maintained for a long time.
