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.
