Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a circuit board fixing device,

The present invention relates to a circuit board fixing device for an LED lighting device, and more particularly, to a circuit board fixing device for an LED lighting device, The circuit board can be cut and used in accordance with the size of the circuit board so that the convenience of use can be improved. In addition, the circuit board can be fixed to an LED lamp or the like which can more effectively cope with the elongation or contraction of the circuit board, ≪ / RTI >

In general, a lighting lamp is installed on a ceiling or a wall surface of a room to illuminate an indoor space. In recent years, it has been variously used as an interior decoration for interior decoration.

Fluorescent lamps, incandescent lamps, or halogen lamps are mainly used as light sources for such illumination lamps. In this case, there is a problem that the power consumption is relatively large, the life is short, and the illuminance is low.

Accordingly, it can be used for a relatively long time compared to conventional lighting lamps such as fluorescent lamps, incandescent lamps, or halogen lamps, and has a very low brightness and a very bright brightness. The LED, which is excellent and can be produced in various colors, is being applied as a light source for illumination.

In order to apply such an LED as a light source of an illumination lamp, a plurality of LEDs are mounted on a circuit board, and a circuit board on which a plurality of LEDs are mounted is mounted on a mounting portion of a housing constituting an LED illumination lamp. A plurality of screw fastening holes are formed on the circuit board which is out of the mounting position of the LED when the mounting board is mounted on the mounting portion of the housing and the screws are fastened to the respective screw fastening holes formed on the circuit board in a state in which the circuit board is in close contact with the mounting portion of the housing The circuit board was attached to the mounting portion of the housing in a manner of fastening.

However, in the conventional circuit board mounting structure of the LED light, since a screw fastening hole must be formed on a circuit board and a plurality of screws must be fastened to the screw fastening hole when assembled, There is a problem that productivity is greatly reduced.

In addition, when the circuit boards are to be replaced as needed, all the screws are loosened, the circuit boards are removed, and a plurality of screws are fastened again in a state in which the new circuit boards are in close contact with each other. The detachment of the circuit board to the circuit board is very troublesome, and the replacement and repair workability of the circuit board is also greatly reduced.

In order to overcome such a problem, Korean Utility Model Publication No. 20-2011-0002982 (name: LED light, hereinafter referred to as "prior art") has been proposed.

The prior art described above has a case having a fixing frame with a plurality of screw holes formed therein; A lamp shade attached to a lower portion of the case by screwing; A heat sink built in the lamp shade and fixed by screwing; A circuit board attached to a lower portion of the heat sink and having a plurality of LEDs; An illumination cover attached to a lower portion of the lamp shade by screwing; And a converter incorporated in the case to supply power to the circuit board.

However, in the above-described prior art, the circuit board having a plurality of LEDs is configured to be attached to the lower portion of the heat sink by double-sided adhesive. In this case, the adhesive force of the double- There is a serious problem that the attachment state of the circuit board is poor or even the risk of falling arbitrarily from the attached state is very high.

It is an object of the present invention to provide a new LED light fixture which can fix the edge of a circuit board applied to an LED lighting fixture and can greatly improve the mounting workability of the circuit board. And to provide a circuit board fixing apparatus.

Another object of the present invention is to provide a circuit board fixing device, such as a new LED light fixture, which can be cut and used in accordance with the size of a circuit board, thereby improving convenience in use.

Another object of the present invention is to provide a new LED lighting fixture such as a new LED lighting fixture which can more effectively cope with the elongation or shrinkage of the circuit board depending on the lighting of the LED lighting.

In order to accomplish the above object, the present invention provides a circuit board having a length corresponding to a length of the circuit board for supporting and fixing a circuit board mounted on an LED illumination lamp, the upper surface of the outer edge of the circuit board being pressed A circuit board fixing piece formed integrally with the circuit board to prevent the edge of the circuit board from being pushed outwardly from the outer side in a vertical direction downward; And a plurality of fastening holes formed on the surface of the fastening hole, the fastening holes being formed at predetermined intervals.

In the present invention, the circuit board fixing piece and the fastening piece are formed with cutting grooves at regular intervals in order to cut the circuit board in accordance with the length of the circuit board.

By applying the present invention, it is possible to fix the edge of the circuit board applied to the LED illumination lamp so that the mounting workability of the circuit board can be greatly improved. In addition, since the circuit board can be cut and used according to the size of the circuit board, Is greatly improved.

In addition, when the LED illumination lamp is turned on, the circuit board is stretched by the heat generated from the LED. In consideration of such a condition, if the edge of the circuit board is supported in a state of being spaced apart from the separation- It is possible to more effectively cope with the variability of the circuit board which is elongated or contracted depending on whether the lighting lamp is turned on or off.
