  In order to describe in detail the technical contents, structural features, and objects to be achieved of the present invention, examples will be described below in combination with the drawings.

  As shown in FIGS. 1 and 2, the LED lighting device capable of adjusting the angle of the present invention includes at least one set of fixed housings 10 each having a generally hollow cylindrical shape. On the fixed housing 10, at least three LED light-emitting plates 20 are installed in an annular shape so as to surround the periphery. Moreover, a base 30 is installed at the bottom end of the fixed housing 10. A blower assembly 31 is provided on the base 30, and an air outlet of the blower assembly 31 is located below the back surface of each LED light emitting plate 20. On the base 30, a slight fixing portion 32 is installed, and thereby the fixing housing 10 is installed and fixed.

  As shown in FIG. 3, movable connection portions 21 are provided on both sides of the bottom end of each LED light-emitting plate 20 and are movably installed in the fixed housing 10. Accordingly, the LED light emitting plate 20 is opposed to the fixed housing 10 with the movable connecting portion 21 as an axis, and is inclined outward or accommodated inward, and stands upright around the fixed housing 10. Thus, the irradiation angle of the LED light emitting plate 20 is adjusted.

  As shown in FIGS. 3 to 5, for the convenience of adjusting the irradiation angle, at the time of implementation, a pull lever 22 is installed on the front side of each LED light-emitting plate 20, and a connecting piece 23 is installed on the back surface. The opposite end of each connecting piece 23 is movably installed on a slide piece 24 extending to the center position of the fixed housing 10. Each of the slide pieces 24 includes a slide tank 25, and the slide tank 25 is fitted and installed on the stereotaxic rod 11 installed at the center of the fixed housing 10. As a result, the slide piece 24 slides inward or outward relative to the stereotaxic rod 11.

  As shown in FIGS. 6 and 7, when a user pushes or pulls the pull lever 22 on the LED light emitting plate 20, the slide piece 24 is moved on the stereotaxic rod 11 through the connecting piece 23 on the back side of the LED light emitting plate 20. Slid inward or outward. That is, as described above, the LED light-emitting plate 20 is tilted outward or stored inward relative to the fixed housing 10 with the movable connecting portion 21 as an axis, and stands upright around the fixed housing 10. . Thus, the irradiation angle of the LED light emitting plate 20 can be adjusted, and the effect of diversifying the irradiation angle can be achieved.

  As shown in FIGS. 3 to 5, a compression spring 12 is installed outside the stereotaxic rod 11 installed at the center of the fixed housing 10. The bottom end of the compression spring 12 compresses each slide piece 24 with elasticity. When the slide piece 24 stops after sliding to an appropriate position on the stereotaxic rod 11, the slide piece 24 is positioned at the position where the slide stops due to the elastic compression of the compression spring 12. In this way, the angle of the LED light-emitting plate 20 is fixed, and the elastic compression of the compression spring 12 prevents the LED light-emitting plate 20 from swinging after adjustment.

As shown in FIGS. 1 and 2, when the base 30 is implemented, a hollow tank 33 is further installed inside.
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. Thereby, the blown-out air is directed to the back surface of the plurality of LED light emitting plates 20 installed in an annular shape and cooled by blowing. Thus, the LED light emitting plate 20 can achieve a good heat dissipation effect.

  At the time of implementation, the LEDs on each LED light-emitting plate 20 are arranged, and in order to protect the LEDs on the LED light-emitting plate 20, the outer surface of the LED light-emitting plate 20 can be covered with a single protective layer. The protective layer also has a waterproof function when the weather is bad.

  As shown in FIGS. 8 and 9, at the time of implementation, a plurality of sets of fixed housings 10 are stacked on top and bottom, and each fixed housing 10 is provided with at least one LED light-emitting plate 20 in an annular shape. As a result, the upper and lower fixed housings 10 are relatively inclined, and thus the upper and lower LED light emitting plates 20 irradiate at different angles and directions, respectively. And more diversified directions.

  For example, the plurality of lower LED light-emitting plates 20 shown in FIG. 10 are arranged at a vertical angle, whereby light rays are emitted far away at a horizontal angle, and the upper LED light-emitting plates 20 are moved downward. It is arranged at an inclined angle, and thus the brightness around the LED lighting device whose angle can be adjusted can be enhanced.

  As shown in the figure, a fence 40 is further fitted and installed outside the fixed housing 10 that overlaps the upper and lower sides. The fence 40 is installed on the base 30 and fixed by the fixing portion 32, and covers the outer periphery of the fixed housing 10 and the LED light emitting plate 20. This prevents erroneous contact of the user with the fixed housing 10 and the LED light emitting plate 20.

  As shown in FIGS. 11 and 12, at the time of implementation, a plurality of alignment holes 13 arranged in an annular manner at equal distances are installed between the fixed housings 10 that are stacked on top and bottom. Thereby, the fixed housings 10 that are stacked on each other can be aligned in various directions. A plurality of bolt assemblies 14 can be passed through the alignment holes 13 and fixed. As a result, the fixed housings 10 stacked on the upper and lower sides can be moved relative to each other by the slide movement method without removing the plurality of bolt assemblies 14. The alignment hole 13 is a general circular hole or an arc-shaped long hole as shown in the figure.

  In this embodiment, the LED light emitting plate 20 of the upper fixed housing 10 and the LED light emitting plate 20 fixed to the lower fixed housing 10 are relatively rotated through rotation adjustment of the positional relationship between the fixed housings 10. To move. As a result, the upper three LED light-emitting plates 20 and the lower three LED light-emitting plates 20 are alternately arranged as shown in FIGS. Form. Alternatively, as shown in FIG. 12, they can be arranged in the same direction to concentrate the light rays into a specific area.

  The names and contents of the present invention described above are only used for explaining the technical contents of the present invention, and do not limit the present invention. All equivalent applications based on the spirit of the present invention, parts (structures) conversion, replacement, and quantity increase / decrease shall be included in the protection scope of the present invention.
