A plurality of heat dissipation blades 130 are formed on the upper surface of the heat sink 110 as shown in FIG. 5, so that heat generated from the LED module 200 is well discharged.

The heat dissipation plate 110, the stage 120, and the heat dissipation wing 130 may be formed of a material having high thermal conductivity, and may be formed of an aluminum material in one embodiment. In the case of aluminum material, it is possible to prevent the rust formed and damaged by the street lamp luminaire by moisture, has the advantage of high thermal conductivity and light.

Wires for supplying power to the LED module 200 are formed in the heat sink 110 and the stage 120, and terminals that are in electrical contact with the LED module are formed on the surface of the stage (not shown).

In addition, the LED module 200 may be directly bonded to the heat sink without the stage 120.

The heat sink 110 has a shape in which the various parts of the heat sink are bent at a predetermined angle so that the plurality of LED modules 200 to be coupled to the heat sink to reflect different directions for efficient lighting. In other words, the two LED modules adjacent to each other is shining light in different directions. In addition, two LED modules neighboring each other are formed at different heights.

In an embodiment of the present invention, the heat sink 110 may be formed of three blocks each of which are bent and formed horizontally, and nine blocks in total. Each of the nine blocks may include a stage 120 and an LED in each stage. Module 200 may be configured to be formed.

That is, the heat sink 110 is bent in two stages in the up and down and left and right directions, divided into three parts up and down, and also divided into three parts left and right. That is, the heat sink 110 is all divided into nine blocks so that all blocks are adjacent to each other with a predetermined angle difference so as not to be parallel to each other.

When the street lamp luminaire according to the present invention is fixed to the lamp post, the bottom row H 31 , H 32 , H 33 in FIG. 4 is closer to the lamp post, and the top row H 11 , H 12 ,. H 13 ) is the part close to the road side.

FIG. 6A is a cross-sectional view of the heat dissipation unit 100 cut based on A, and FIG. 6B is a side view viewed from the opposite side.

Referring to (a) and (b) of Figure 6 will be described a structure bent in the longitudinal direction of the heat sink (110).

The heat sink 110 is bent in an S shape in the longitudinal direction of the drawing. Therefore, the heat sink 110 may be largely divided into first block rows H 11 to H 13 , second block rows H 21 to H 23 , and third block rows H 31 to H 33 . The angle a1 formed between the first block rows H 11 to H 13 and the second block rows H 21 to H 23 is bent to be between 5 degrees and 15 degrees.

In addition, the angle a2 formed between the second block rows H 21 to H 23 and the third block rows H 31 to H 33 may also be bent to be between 5 degrees and 15 degrees, The direction in which H 31 to H 33 are bent is bent so as to be opposite to the first block rows H 11 to H 13 .

If the angle (a1, a2) is less than 5 degrees, the area that shines the light is too narrow, there is no significant effect compared to the planar structure, If the angle (a1, a2) is larger than 15 degrees, the area that shines the light is too wide, the light is dispersed There is a problem that the illuminance is lowered.

Preferably, when the angles a1 and a2 are about 6 degrees, the light efficiency is the highest.

Due to the configuration as described above, when the actual luminaire is installed on the post, the second row of blocks H 21 to H 23 illuminates the lower part of the luminaire, and the first row of blocks H 11 to H 13 is slightly forward in the road side direction. And the third block row (H 31 ~ H 33 ) can be prevented from excessively shining the back surface of the holding.

In addition, according to another embodiment of the street lamp luminaire according to the present invention, the length L1 of the first block rows H 11 to H 13 , the length L 2 of the second block rows H 21 to H 23 , and the third The length L3 of the block rows H 31 to H 33 may be different. In addition, by installing a different number of LED module 200 for each block row may be configured to adjust the illuminance of each block.

7 is a cross-sectional view of the heat sink cut in the transverse direction. In this case, the heat sink 110 is bent in two stages in a U-shape in the horizontal direction of the drawing, and the first block rows H 11 to H 31 , the second block rows H 12 to H 32 , and the third It may be divided into block rows H 13 to H 33 , and an angle a3 formed between the first block rows H 11 to H 31 and the second block rows H 12 to H 32 is 20 to 10 degrees. It has a shape bent to be between degrees.

In addition, the angle a4 formed by the second block rows H 12 to H 32 and the third block rows H 13 to H 33 may also be bent to be between 10 degrees and 20 degrees, and the third block rows. H 13 to H 33 are bent in the same direction as the first block rows H 11 to H 31 , and have an overall bowed shape.

When the angles a3 and a4 are less than 10 degrees, the area for illuminating the light is too narrow to have a large effect as compared to the planar structure. If the angles a3 and a4 are less than 10 degrees, the area for the light is too much to the left and right and the illuminance There is a problem of being lowered.

Preferably, when the angles a3 and a4 are about 12 degrees, the light efficiency is the highest.

Due to the configuration as described above, when the actual luminaire is installed on the post, the second block rows H 12 to H 32 illuminate the lower part of the luminaire, and the first block rows H 11 to H 31 illuminate the front in the left direction. The third block rows H 13 to H 33 are more shined in the right direction, so that a larger area than the overall planar structure can be shined.

Thus, when having a shape bent at a predetermined angle, it is possible to project a larger area than the planar structure. However, in the case of illuminating a large area, the phenomenon that light is relatively dispersed and illuminance occurs.

The street lamp luminaire according to the present invention is configured to reduce the radiation angle of the light emitted from the light source using the lens 300 as described above in order to prevent such a problem. In this case, while irradiating a large area at the same time it is possible to prevent the light from being deteriorated due to the dispersion of light.

The heat dissipation plate 110 configured as described above may be configured such that a plurality of blocks H 11 to H 33 pieces are coupled to each other at a predetermined angle so that the LED modules formed in each block irradiate light in different directions.

In the above description, a form divided into nine blocks has been described as an embodiment of the present invention, but the present invention is not limited thereto, and includes all cases in which LED modules formed in each block are combined to irradiate different directions.

8 to 11 is a view showing the structure of the lower case of the street lamp luminaire according to the present invention.

8 is a view showing a view from the top of the lower case, Figure 9 is a view showing a view from the bottom of the lower case.

8 and 9, the lower case 600 of the street lamp luminaire according to the present invention is configured to be coupled to the heat dissipation unit 100.

The lower case 600 is provided with a plurality of holes 610 through which the light irradiated from the LED module 200 formed in the heat dissipation part 100 can pass.

The hole 610 is formed at the position of the lower case 600 corresponding to the position where the stage 120 of the LED module 200 or the heat dissipation part 100 is formed, and the heat dissipation part 100 and the lower case 600 are formed. When bonded, the rounded portion of the lens 300 surrounding the LED module 200 protrudes through the hole.

A groove in which the pad 500 is mounted may be formed around the hole 610.

The lower case 600 protects the LED module 200 from foreign matters such as dust introduced from the outside, impact, or other moisture.

10 and 11 are cross-sectional views of the lower case according to the present invention cut along the C and D of FIG.

10 and 11, the lower case 600 has a structure in which its cross section is bent at a predetermined angle, like the heat sink 110. Hereinafter, a detailed description of the configuration of the surface of the lower case bent in various directions will be omitted because it is substantially the same as the structure of the heat sink.

The streetlight luminaire according to the present invention described above has a form of bending twice each in the horizontal and vertical directions, that is, the form of bending in two stages, but may be of three or more times (three or more stages).

Although the street lamps according to the present invention have been described with reference to the illustrated drawings as described above, the present invention is not limited by the embodiments and drawings disclosed herein, and may be applied within the scope of the technical idea.

The street lamp luminaire according to the present invention configured as described above has an advantage that the power consumption is low because the LED module is used as the light source, and the low current and the low voltage can be driven, thereby reducing the damage caused by the short circuit.

In addition, since all LED modules of the street lamp are irradiated in different directions, there is less glare and can illuminate a larger area than the planar structure, and even if the large area is illuminated, the angle of emission of light emitted by the lens is controlled. The light efficiency can be improved without losing brightness.

In addition, the heat emitted from the LED module is discharged to the outside by the heat dissipation blade to which the LED module is fixed and the heat dissipation blade formed on one surface of the heat sink has the effect of preventing excessive heat generated.
