In addition, the present invention implements a LED driving circuit excluding a separate configuration for stepping down voltage for commercially available AC power supply voltage to implement the product simplification and light weight, the LED driving circuit can be driven more stably Each drive circuit including LEDs is divided into blocks for a single power source, and the LEDs have 2 extended connection configurations in one longitudinal direction so that the arrangement of each drive circuit and the elements constituting the drive circuits is optimized. It relates to a lighting device.
At the same time, the present invention allows a plurality of light emitting chips to be connected in series in an SMD (Surface Mount Devices) type LED device to further simplify the configuration of the product, and the The present invention relates to an LED lighting device having an extended connection configuration in one longitudinal direction to optimize the number of arrays so that the power factor and light efficiency are excellent.
In particular, the present invention mounts the elements of the LED driving circuit in the form of Surface Mount Technology (SMT) on the printed circuit board, and molding the thermal conductive material on the printed circuit board mounted with each device on the LED and the driving circuit The present invention relates to an LED lighting device having an extended connection configuration in one longitudinal direction to improve heat dissipation efficiency and minimize leakage current emitted on a printed circuit board to improve power supply efficiency.
The lighting device applied to the interior space lighting of the building using the LED is mainly applied to the main lamp of the room or the office, the table stand, etc., and can further illustrate the lighting tile using the light guide plate in a more advanced form.
With this lighting device, LED lamps are arranged in a tubular form by combining a tube-shaped light transmission cover that allows LEDs to be arranged in a line with the longitudinal direction and transmits and emits the light of the LED. It is becoming.
The lamp device is coupled to the fluorescent lamp socket installed in the ceiling or wall of the space. Such a lighting device is accompanied by an A / D converter due to the characteristic that the LED is driven by a DC current of a suitable voltage.
The A / D converter as described above includes a transformer coil for stepping down alternating current, and such a transformer coil is disposed at a considerable size in the LED module, which causes a problem in that a product to which it is applied is enlarged.
In order to solve the above problems, a power supply device called a switching mode power supply (SMPS) is recently applied. For reference, the SMPS is used by converting an alternating frequency (50 Hz ~ 60 Hz) into a direct current to a high frequency (tens dozens of hundreds ~ hundreds of kHz), according to the technology of high difficulty.
In addition, the conventional LED lighting device has been proposed to drive the LED according to the voltage drop in each LED for the power source by connecting a plurality of LEDs in a configuration in which SMPS is excluded.
In this case, the LED lighting device is an LED drive circuit by the LED part mounted by mounting a plurality of LEDs on a printed circuit board, and the drive circuit part is installed on a separate printed circuit board several elements for driving the LED. It is configured and applied.
Here, the LED is mainly applied to the SMD-type device, which is known that the two or more light emitting chips are connected in parallel in the device of the built-in compact structure.
The conventional tubular lamp device as described above is produced in accordance with the existing fluorescent lamp standard is set in length. On the other hand, ordinary fluorescent lamps must be filled with a single tube-type tube, because fluorescent materials must be filled inside, while tube-type lamps manufactured using LEDs as light sources can perform their functions without having a sealed configuration. Nevertheless, it is conventionally manufactured to the same standard as the fluorescent lamp.
It is difficult to cope with various sizes and shapes of the space for realizing lighting, and in particular, it is difficult to cope with various lighting in the space due to its simple shape. This is extremely limited.

In this case, instability occurs because the entire LED group itself is not driven.
In addition, since SMD-type LEDs, which are mainly applied to the LED lighting device, are connected in parallel with light emitting chips inside them, it is very inconvenient to set the voltage drop value generated in each device even when the LEDs are connected in series. In order to prepare a number of LEDs in the series connection, a large amount of LEDs are required regardless of the number of built-in LEDs.
In particular, the LED lighting device generates a considerable heat due to the driving characteristics of the LED, it is applied to the heat sink coupled to the printed circuit board in a configuration for dissipating the heat to the outside.
