Each LED light-emitting plate 41 is installed in a ring shape on one set or a plurality of sets of fixed housings 42 that overlap the upper and lower sides. In this embodiment, two sets of fixed housings 42 that overlap the upper and lower sides are installed. The bottom end of the lowermost fixed housing 42 and the base 30 are connected to each other, so that the LED lighting apparatus can include one set or multiple sets of the fixed housing 42 and the LED light emitting plate 41 according to various usage locations. In addition, the irradiation angle and direction can be diversified. At the time of implementation, in order to protect the LED on the LED light-emitting plate 41, the outer surface of the LED light-emitting plate 41 can be covered with a single protective layer. The protective layer also has a waterproof function when the weather is bad.

  The fence 50 is installed on the base 30 and fixed by the fixed frame 32, and covers the outer periphery of the lighting assembly 40. This prevents a person from approaching and accidentally touching the lighting assembly 40. In practice, it can also be used to secure and connect other articles, and structural reinforcement connections can be made with the lighting assembly 40.

  As shown in FIGS. 2 and 3, which are cross-sectional views of the lighting assembly 40, the base 30 includes a hollow tank 33. The air outlet of the blower assembly 31 leads to the hollow tank 33. In addition, a filter 34 is installed at the bottom of the base 30, whereby air passes through the filter 34 and enters the hollow tank 33 and is sucked into the blower assembly 31. The air outlet of the blower assembly 31 is connected to the flow guide portion 35 installed on the base 30.

Thus, the irradiation angle of the LED light emitting plate 41 can be adjusted.

  At the time of implementation, a pull lever 44 is installed on the front side of each LED light-emitting plate 41, and a connecting piece 45 is installed on the back surface. The opposite end of each connecting piece 45 is movably installed on the slide piece 46 and extends to the center position of the fixed housing 42. Each slide piece 46 includes a slide tank 461, and the slide tank 461 is fitted and installed on a stereotaxic rod 47 installed at the center of the fixed housing 42. Thereby, each slide piece 46 slides inward or outward on the stereotaxic rod 47.

  As shown in FIGS. 5 to 8, when the user pushes or pulls the pull lever 44 on a certain LED light-emitting plate 41, the slide piece 36 is placed on the stereotaxic rod 47 through the connecting piece 45 on the rear surface of the LED light-emitting plate 41. And slides inward or outward. Thereby, as described above, the LED light emitting plate 41 is tilted outward or stored inward relative to the fixed housing 42 with the movable connecting portion 43 as an axis, and stands upright around the fixed housing 42. Thus, the irradiation angle of the LED light emitting plate 41 can be adjusted, and the effect of diversifying the irradiation angle can be achieved.

  In addition, a compression spring 48 is fitted and installed outside the stereotaxic rod 47 installed at the center of the fixed housing 42. The bottom end of the compression spring 48 compresses each slide piece 46 with elasticity. When a slide piece 46 of a certain LED light-emitting plate 41 slides to an appropriate position on the localization rod 47 and stops, the slide piece 46 is localized at a position where the slide stops due to elastic compression of the compression spring 48. In this way, shaking of the LED light-emitting plate 41 after localization is prevented. As shown in FIGS. 9, 10, and 11, which are an external view of the lighting assembly 40 according to the embodiment of the present invention, a three-dimensional external view of the fixed housing 42, and schematic views of the irradiation direction, the external appearance of the fixed housing 42 is a hollow cylindrical shape.
