  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 lighting device of the present invention includes at least two sets of fixed housings 10 that overlap the upper and lower layers. On each fixed housing 10, a plurality of LED light emitting plates 20 are installed in an annular shape.
Three LED light-emitting plates 20 are annularly installed on each fixed housing 10 shown in the present embodiment. The LED light emitting plate 20 is composed of an array type LED, and the outer surface is covered with a single protective layer (not shown) and has a waterproof function.

The overall appearance of the fixed housing 10 has a generally hollow cylindrical shape. Between the fixed housings 10 that overlap the upper and lower layers, a plurality of alignment holes 11 that are annularly arranged at equal distances are provided.
As a result, the fixed housings 10 that overlap the upper and lower layers can be aligned in a relatively inclined manner in multiple directions. A plurality of bolt assemblies 12 can be passed through the alignment holes 11 and fixed.

  The alignment hole 11 is a general circular hole or an arc-shaped long hole as shown in the figure. Alternatively, as illustrated, the alignment hole 11 installed on the lower fixed housing 10 may be a circular hole, and the alignment hole 11 installed at a relative position of the upper fixed housing 10 may be an arc-shaped elongated hole. . As a result, the fixed housing 10 overlapping the upper and lower layers can be relatively tilted by a sliding movement method without removing the bolt assembly 12.

  As shown in FIGS. 3 and 4, in this embodiment, the LED light emitting plate 20 of the upper fixed housing 10 and the LED light emitting plate 20 of the lower fixed housing 10 are adjusted by turning the corresponding positional relationship between the fixed housings 10. , Relatively adjust the position. As a result, the upper three LED light-emitting plates 20 and the lower three LED light-emitting plates 20 are arranged in a staggered manner to form light rays that are uniformly emitted outward in six directions.

  As shown in FIGS. 5 and 6, the three LED light-emitting plates 20 of the upper-layer fixed housing 10 and the three lower-layer fixed housings 10 are adjusted through the pivotal adjustment of the positional correspondence between the upper and lower fixed housings 10. The LED light emitting plates 20 are arranged in an overlapping manner. Thereby, the light rays of the upper and lower LED light-emitting plates 20 are emitted in a concentrated manner at a specific angle. Thus, the lighting device can emit a relatively concentrated irradiation beam.

As shown in FIGS. 7 and 8, in this embodiment, a base 30 and a fence 40 are added as compared with the first embodiment. The bottom end of the fixed housing 10 located in the lowermost layer and the base 30 are connected. A blower assembly 31 is provided on the base 30.
The air outlet of the blower assembly 31 is located below the back surface of each LED light emitting plate 20. Moreover, a fixed frame 32 is installed on the base 30, thereby fixing the fixed housing 10 positioned at the lowermost layer.

  A hollow tank 33 is further installed in the base 30. 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. As a result, the blown-out air is directed to the back surface of the plurality of LED light emitting plates 20 installed in a ring shape, and heat is forcibly dissipated. Thus, the LED light emitting plate 20 can achieve a good heat dissipation effect.

  As shown in FIGS. 8 to 10, at the time of implementation, 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, is inclined outward or is accommodated inward, and stands upright around the fixed housing 10. Thus, the irradiation angle of the LED light emitting plate 20 is adjusted.

In order to facilitate the adjustment of the irradiation angle, 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 side. 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 a stereotaxic bar 13 installed at the center of the fixed housing 10.
As a result, the slide piece 24 slides inward or outward relative to the stereotaxic bar 13.

When a user pushes or pulls the pull lever 22 on the LED light emitting plate 20, the slide piece 24 slides inward or outward on the stereotaxic rod 13 through the connecting piece 23 on the back side of the LED light emitting plate 20. .
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.

In addition, as shown in the figure, a compression spring 14 is installed outside the stereotaxic bar 13 installed at the center of the fixed housing 10. The bottom end of the compression spring 14 compresses each slide piece 24 with elasticity.
When the slide piece 24 stops after sliding to an appropriate position on the stereotaxic rod 13, the slide piece 24 is positioned at the position where the slide stops due to the elastic compression of the compression spring 14.
In this way, the angle of the LED light-emitting plate 20 is fixed, and the elastic compression of the compression spring 14 prevents the LED light-emitting plate 20 from swinging after adjustment.

As shown in FIG. 11, in the embodiment of adjusting the angle of the LED light-emitting plate 20, the LED light-emitting plate 20 can be arranged at a vertical angle in addition to being inclined, so that the light beam is at a horizontal angle. Irradiated far away.
That is, when the plurality of LED light emitting plates 20 installed in a ring shape on the fixed housing 10 are operated and emit light, light can be irradiated in all directions at the same time. Furthermore, if the upper and lower LED light-emitting plates 20 are arranged alternately and alternately, the entire lighting device can achieve various usage methods according to the usage environment.

  As shown in the figure, a fence 40 is further fitted and installed outside the upper and lower fixed housings 10. The fence 40 is installed on the base 30 and fixed by the fixed frame 32, thereby preventing the user from accidentally contacting the fixed housing 10 and the LED light emitting plate 20.

As shown in FIG. 12, in this embodiment, a stand 50 is installed at the bottom end of the base 30 compared to the second embodiment. A power supply device 60 is installed on the stand 50. The bottom end of the stand 50 can be unfolded and can be easily installed in any environment. At the time of implementation, if necessary, the height adjuster 51 can extend the stand 50 upward to adjust the height.
The power supply device 60 is installed at a relatively low position on the stand 50 and has a function of supplying power, and can exert an appropriate weight effect on the stand 50.
Thereby, the stand 50 becomes difficult to wobble and the stability at the time of installation improves.
