DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of this embodiment, the same name and the same reference numerals are used for the same configuration and additional description thereof will be omitted.

3 is an exploded perspective view showing the LED lighting fixture of this embodiment.

The LED lighting device according to the present embodiment may include a main body 1, a cover 2, a printed circuit board 6, and a supporter 7.

The main body 1 is attached to a ceiling or a wall inside the building, and is formed such that an accommodating part 11 in which the printed circuit board 6 is accommodated is formed. In addition, the receiving portion 11 may be formed with a fixing groove (H1).

The cover 2 is made of a transparent or semi-transparent material so as to transmit light, and is removable to cover the receiving portion 11 of the main body (1). The male screw portion formed in the cover 2 may be coupled to the main body and the cover through rotation in accordance with the female screw portion formed in the main body.

As shown in FIG. 4, the printed circuit board 6 is printed with a circuit, and a plurality of LED packages 62 mounted with LEDs are coupled to each other. In addition, a terminal block 63 for supplying power to the printed circuit board 6 and the LED package 62 may be provided at one side of the printed circuit board 6. The terminal block 63 is made to be coupled to an external wiring to which power is applied. In addition, a coupling groove H2 is formed in the printed circuit board 6.

Meanwhile, as shown in FIG. 5, the supporter 7 includes a rod 71 having a longitudinal direction to one side and a coupling groove H2 of the printed circuit board 6 at one end of the rod 71. A fitting protrusion 72 to be coupled is formed, and a hook 73 coupled to the fixing groove H1 of the main body 1 may be formed at the other end of the rod 71.

The fitting protrusion 72 and the hook 73 may be made in the shape of a wedge, and may be made of a soft material or a flow structure such as synthetic resin so that the operator can easily press and detach.

In addition, the supporter 7 has the fitting protrusion 72 and the hook of the supporter 7 coupled to the coupling groove H2 of the printed circuit board 6 and the fixing groove H1 of the main body 1, respectively. It may further comprise a departure preventing piece 74 for pressing to one side so that 73 is not removed.

As shown in FIG. 5, the release preventing piece 74 may be pressed in the direction in which the hook 73 is pulled to prevent the hook 73 fixed to the fixing groove H1 from being removed. Since the pressed hook 73 has a wedge shape, the hook 73 is prevented from coming into close contact with the fixing groove H1. In addition, since the hook 73 is in close contact with the fixing groove (H1), the rod 71 may also be perpendicular to the receiving portion (11). In addition, the separation preventing piece 74 may be formed on the fitting protrusion 72 side.

On the other hand, the main body 1 and the cover 2 as described above are the same as the conventional one, it is also possible to utilize a conventional ready-made product. That is, by using the supporter 7 suitable for the size of the coupling groove (H2) formed in the receiving portion 11 of the main body 1, the printed circuit board 6 to the receiving portion 11 of the conventional main body 1 ) Can be fixed.

Alternatively, when the fixing groove (H1) is not formed in the receiving portion 11 of the main body 1 may be formed by processing the fixing groove (H1).

As such, the socket 5 and the light bulb 4 into which the existing current is inserted are removed, and a wire to which an external power is applied is connected to the terminal block 63, and then the supporter 7 is connected to the coupling groove H2. The coupling can be easily realized by coupling the hook 73 of the supporter 7 to the fixing groove H1 while accommodating the printed circuit board 6 to the receiving portion 11 formed in the main body.

In addition, the LED lighting device may further include a sensor 3, as shown in FIG. The sensor 3 is a component that detects whether there is an object such as a user in the lighting range of the LED lighting apparatus, and may be configured to turn on or off the LED of the LED lighting apparatus according to the detection result of the sensor. The sensor 3 may be provided on one side of the main body 1.

Figure 6 is a control circuit block diagram of a printed circuit board applied to the LED lighting fixture of the present invention. The control circuit of the printed circuit board 6 receives an external AC power and converts a current in a (-) state into a current in a (+) state to rectify it to a DC, and prints the rectified power. The booster 82 boosts the voltage required by the circuit board, the constant current supply unit 83 supplying a constant current to the printed circuit module with respect to the boosted voltage, and the current supplied from the constant current supply unit 83. The LED package 62 which emits light and the brightness adjusting part 84 which adjusts the brightness of the LED package 62 by a user operation etc. are comprised.

In this case, the rectifier 81 uses a conventional bridge diode composed of four diodes, and the booster 82 usually uses an electrolytic capacitor.

In addition, the constant current supply unit 83 uses a constant current diode (CRD), and a plurality of constant current diodes are connected and used in parallel in order to supply a current required by the LED package 62.

In addition, the brightness controller 84 includes a dip switch 851 and a light emitting diode 852. As shown, the path through the light emitting diode 852 is changed according to the selection of

switches

1, 2, and 3, and accordingly, the number of LEDs emitting from the LED package is determined so that the LED package module 62 ) Brightness is adjusted. On the other hand, the same function can be obtained by using a 0 ohm resistor or a short pin as a substitute for the dip switch 851.

In addition, when the aforementioned sensor is added, a sensor module (not shown) may be further formed between the input terminal of the external AC power source and the rectifying unit.
