Description

TECHNICAL FIELD [0001] The present invention relates to a LED lighting apparatus,

The present invention relates to an LED lighting device having a ventilation hole, which is capable of rapidly dissipating heat generated by the LED lamp being lighted while covering and protecting the LED lamp module, and accumulating dust, foreign matter, So that the heat radiating function can be maintained for a long time.

In general, fluorescent lamps and incandescent lamps are mainly used as lamps. In this case, there is a problem that power consumption is relatively high, life is short, and illuminance is low.

Accordingly, recently, a relatively long and bright LED having a relatively long power consumption is applied to a lighting apparatus.

Such an LED lighting device is installed outdoors, such as a streetlight or a security lamp installed outside a house, and requires a large amount of light to be protected against an external force, so that a corresponding number of LEDs are installed in a metal case.

Particularly, it is well known that a street lamp (hereinafter, LED street lamp lighting device) among the above LED lighting devices is installed in a considerable number in a unit point, so that it is used as a lighting device at a desired point by receiving AC power from a local power generation facility .

As described above, the LED street lamp lighting device installed in the outdoor (the lighting device is described as including all the lighting devices such as the security lamp used in the outdoors) plays the role of holding or holding for installation at a certain height outside the room And an illuminating unit for illuminating the light mainly on the outer wall of the building under direct or lower angle.

Here, the illuminating unit may include a case made of a metal material, a light transmitting cover for transmitting and emitting light from the lower side of the case, as described above, and a plurality of LEDs and an external power source are received in the case, And a printed circuit board on which electric and electronic parts for driving are mounted.

In particular, since the LEDs emit a considerable amount of heat due to the characteristics of the LED driving circuit, a considerable amount of heat is also emitted from the printed circuit board on which the LEDs are mounted. Therefore, And the heat sink is constructed as a street light.

Among the components for driving the LED, the SMPS for converting the power inputted from the outside into the LED driving power source is installed in the capacity corresponding to the number of LEDs and the power used for the streetlight and the size thereof.

At this time, the SMPS has a structure that is fixedly mounted on the inner wall surface of the case by brackets or self-fixing means such as bolts.

In the conventional LED street light illumination device, the heat sink attached to only one side of the printed circuit board is manufactured in a considerable size in consideration of the size of the street light, so that the street light illumination unit is enlarged. In addition, since the heat sink discharges only the heat radiated from the printed circuit board inside the case, the heat radiation efficiency is low, which causes the inconvenience of the administrator inspecting the heat sink frequently. In addition, since the SMPS used in the LED street light lighting apparatus is manufactured to have a considerable size in order to cope with the consumption power of the street light, the street light lighting unit is heavily constructed. Therefore, inconvenience of transportation and construction of the street light, And increases the amount of materials and materials to be used in consideration of the strength of each component for supporting the weight, thereby raising the problem of raising the manufacturing cost of the product.

In view of this, Patent Application No. 10-2008-0136075 discloses an LED streetlight lighting apparatus having a self-heat-dissipating function.

A conventional LED street light illumination apparatus has a lighting unit including an LED lighting circuit inside the case. The LED street lighting apparatus includes an LED lighting circuit and a case coupled to the LED lighting circuit, The LED lighting circuit includes an LED driving circuit unit for rectifying and supplying a commercial power source to be supplied to the LED driving circuit unit, The LED driving circuit and the LED array part are driven by a voltage of 1: 1 to 1: 1, respectively, so that the LED driving circuit and the LED array part are driven by a voltage of 1: A plurality of block unit circuits are connected in parallel to a single commercial power supply, The.

However, the conventional LED streetlight lighting apparatus having such a general self-heat-dissipating function as described above has a problem that since the upper surface of the case is formed as a flat surface as described above, dust, foreign matter or bird discharge accumulates with time, There is a disadvantage that the function can not be maintained.
