The assembly is made while the 54 is placed on the upper side of the side portion 34 of the main body 30.

Subsequently, two cap members 50 are respectively inserted from both ends of the main body 30 so as to surround the round part 56 of the light transmitting member 50 and the outer surface of the main body 30. ) Assembly is completed.

In the assembled state, the lighting fixture 10 is installed in the installation structure 20, such as a building, a common house, a street lamp mounting stand, and supplies power, so that a plurality of LEDs 42 are turned on and irradiated with LED light. It is used while illuminating the outside via the penetrating member 50.

At this time, when a strong wind or a typhoon blows to the lighting fixture 10 installed outside, as shown in Figure 3, along the surface guide surface of the heat dissipation guide portion 80 provided in the side portion 34 of the main body 30 Move upward while moving.

In addition, the wind moved upwards passes through the round part 56 of the light transmitting member 50 and moves out along the surface guide surface of the opposite heat dissipation guide part 50, thereby exiting the luminaire 10. The eddy phenomenon that occurs while hitting the side of the main body 30 is prevented.

On the other hand, while moving along the space between the curved protrusion 92 and the curved groove portion 94 of the auxiliary heat radiation guide portion 90 formed in the heat radiation guide portion 80 helps to increase the movement efficiency of the wind.

At this time, the curved protrusion 92 and the valley groove 94 of the auxiliary heat radiation guide portion 90 serves to support the wind movement of the heat radiation guide portion 80 and at the same time reinforce the strength.

As shown in FIG. 5, the assembled state and the used state of the LED lighting device 10 having the heat dissipation structure according to the second embodiment of the present invention will be described. Since 180 is formed to be flat without the bending protrusions 92 and the bending grooves 54, detailed descriptions thereof will be omitted.

Since the heat dissipation guide part 180 according to the second embodiment is formed with a flat curved surface, the heat dissipation guide part 180 may be manufactured by extrusion or injection molding integrally with the main body 30.

As such, when the wind blows from the side surface of the luminaire 10, the wind moves along the heat dissipation guide part 180 having a hollow valley surface to pass the heat dissipation guide part 180 on the opposite side through the light transmitting member 50. It will pass through.

As shown in FIG. 6, the assembled state and the used state of the LED lighting device 10 having the heat dissipation structure according to the third embodiment of the present invention are almost the same as those of the first embodiment, and only light transmission. There is a difference only in the configuration in which the coupling part 60 is further provided so that the member 50 is firmly fixed to the side part 34 of the main body 30.

An elastic groove 62 is formed on the inner side surface of the side portion 34 of the main body 30 so as to face each other, and is elastic on both side surfaces of the fitting portion 51 of the light transmission member 50 so as to fit into the elastic groove 62. The projection 64 is formed.

The elastic protrusions 64 and the elastic grooves 62 are preferably formed in a hemispherical shape to facilitate mounting and separation. That is, at the time of mounting and detachment, the elastic protrusion 64 of the side portion 34 is elastically compressed and at the same time, the side portion 34 of the main body 30 is mounted and separated while being slightly opened. In addition, the process of moving the wind is the same as the first and second embodiments, detailed description thereof will be omitted.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand.
