A substantially teardrop-shaped glove 8 having a geometrically combined shape is attached to the main body 4 so as to cover the attachment cover body 6 and the light source part 7 from above. The globe 8 is formed of a resin material having optical transparency such as polycarbonate, or a glass material.

Next, the light source unit 7 will be described in detail.
The light source unit 7 is configured by connecting a plurality of spherical light source bodies (LED light source bodies) 10 up and down. In this embodiment, the number of connected spherical light source bodies 10 is two.
FIG. 4 is an exploded perspective view showing the configuration of the spherical light source body 10.
The spherical light source body 10 has a mounting recess 12 having a substantially rectangular flat bottom surface 12 </ b> A formed on the surface of a mounting body 11 formed by forming a thermally conductive material in a substantially spherical shape. Installed and configured.

As shown in FIGS. 4 and 5, the LED unit 13 constitutes an LED light source 21 including a lens body 20 formed of a resin material such as acrylic resin in a bullet shape and an LED element (not shown). The lens body 20 is mounted on a mount substrate 22 formed of a high thermal conductivity material, and the light distribution characteristics can be controlled by adjusting the shape of the lens body 20.
A screw hole 23 is provided in the mount substrate 22, and the LED unit 13 is attached to the mounting recess 12 of the mounting body 11 in a replaceable manner through the screw 14 through the screw 14. When the LED unit 13 is mounted, the mounting substrate 22 of the LED unit 13 and the bottom surface 12A of the mounting recess 12 are in surface contact, and the heat generated by the LED unit 13 is thermally conducted to the mounting body 11, and the surface of the mounting body 11 is mutually connected. Heat is efficiently radiated from the radiating fins 15 formed side by side at regular intervals.
In the present embodiment, the two LED units 13 are attached to the spherical light source body 10, and a vertical center line C passing through the center O of the spherical attachment body 11 is vertically set as shown in FIG. When the angle θ = 0 degrees, the LED units 13 are mounted such that the irradiation directions A1 and A2 are the vertical angle θ1 = 45 degrees and the vertical angle θ2 = −45 degrees.

Next, the connection structure between the spherical light source bodies 10 will be described. The spherical light source body 10 and the mounting cover body 6 or the spherical light source body 10 and the other spherical light source bodies 10 are as shown in FIG. They are connected by a hollow ring-shaped connecting member 40.
Specifically, as shown in FIG. 6A, insertion portions 30A are formed at two locations where the center line C and the surface of the attachment body 11 intersect, that is, at the upper and lower extreme points of the sphere. Tubular convex portions 41 forming the connecting shaft formed on the upper and lower sides of the connecting member 40 are inserted into the insertion portion 30A to connect the spherical light source bodies 10 up and down. Further, as shown in FIG. 3, the connecting member 40 is also inserted into the top portion 6A of the mounting cover body 6, and the insertion portion 30A of the spherical light source body 10 is inserted into the convex portion 41 of the connecting member. Thus, the spherical light source body 10 and the mounting cover body 6 are connected vertically.
The spherical light source body 10 connected by the connection member 40 can rotate around the axis of the convex portion 41 serving as a connection axis, and accordingly, the horizontal angle direction irradiated by the two LED units 13 of the spherical light source body 10 is appropriately set. It becomes possible to adjust to.

  Further, as shown in FIG. 6B, the insertion portion 30B is also provided at two locations where the center line Ca inclined by θ3 (= about 45 degrees) with respect to the center line C and the surface of the attachment body 11 intersect. The irradiation directions A1 and A2 of each LED unit 13 can be adjusted by the angle θ3 in the vertical angle direction depending on which of the insertion portions 30A and 30B is inserted into the convex portion 41 of the connecting member 40. It has become.

Accordingly, when a plurality of spherical light source bodies 10 are connected by the connecting member 40, the irradiation directions A1 and A2 of the LED units 13 of the respective spherical light source bodies 10 are rotated with respect to the convex portion 41 of the connecting member 40 and the convex portions 41. The light source unit 7 can be provided with various light distributions by appropriately adjusting depending on the selection of the insertion portions 30A and 30B for inserting the light source.
For example, in the example shown in FIG. 1, the range surrounding the pole 2 is illuminated by attaching the upper spherical light source body 10 to the lower spherical light source body 10 in a posture rotated by 90 degrees. Further, for example, as shown in FIG. 7, the upper and lower spherical light source bodies 10 are attached in a posture to irradiate the same direction. Can be increased.
In addition, since the spherical light source body 10 is formed in a spherical shape, the spherical light source body 10 blocks light emitted from other spherical light source bodies 10 even when the spherical light source bodies 10 are connected vertically. Is prevented and the lighting efficiency is increased.

  Further, the connecting member 40 that connects the spherical light source bodies 10 up and down is arranged on the connecting line with the center line C or Ca of each spherical light source body 10, and the connecting axis by the connecting member 40 is the diameter of each spherical light source body 10. Since it is arranged in R (see FIG. 6), for example, a support plate or the like is arranged on both sides of each spherical light source body 10, and the spherical light source body 10 is supported by being sandwiched from both sides by these support plates. Compared with the structure, light directed in the horizontal direction (lateral direction) from the spherical light source 10 is not shielded by the support plate, and light can be irradiated in any direction around the coupling axis.

The spherical attachment body 11 of each spherical light source body 10 is configured to be separable into two upper and lower hemispheres 11A and 11B, and the two LED units 13 are attached to the lower hemisphere 11B. . As shown in FIG. 8, a communication chamber 16 communicating with the insertion portion 30A is formed inside the hemisphere 11B, and an LED unit attached to the surface of the hemisphere 11B is formed in a part of the communication chamber 16. A lead-in hole 35 for drawing 13 lead wires (conductive wires) 25 into the communication chamber 16 is formed.
In FIG. 8, only one of the lead wires 25 of the two LED units 13 is shown. Although not shown, the communication chamber 16 communicates with the insertion portion 30B in addition to the insertion portion 30A.

Although not shown, the upper hemisphere 11A communicates with each of the insertion portions 30A and 30B, and when the hemispheres 11A and 11B are joined, the hemisphere 11A communicates with the communication chamber 16 of the hemisphere 11A. A room having substantially the same shape as the communication room 16 is formed.
Accordingly, in each spherical light source body 10, the lead wire 25 of the LED unit 13 is guided to the internal communication chamber 16, and the other spherical bulbs disposed below through the insertion portion 30 </ b> A or 30 </ b> B and the hollow connecting member 40. It is introduced into each light source body 10. Similarly, the lead wires 25 are sequentially passed through the spherical light source bodies 10 and connected to the power supply device 5 built in the main body 4.

Thereby, since the lead wire 25 of the LED unit 13 is connected to the power supply device 5 housed in the main body portion 4 through the inside of the spherical light source body 10, the lead wire 25 is not exposed to the outside, and the appearance is impaired. There is no.
Moreover, since the attachment body 11 of the spherical light source body 10 is separable into hemispherical bodies 11A and 11B, when the insertion portions 30A and 30B for inserting the connecting member 40 are changed, the changed insertion portions 30A and 30B are changed. The operation of reinserting the lead wire 25 can be easily performed.

As described above, according to the present embodiment, since the light source unit 7 is configured by including the spherical light source body 10 in which the two LED units 13 are provided on the surface of the attachment body 11 made of the heat conductive material, the lamp Compared to an outdoor lighting device equipped with a light source and a reflector, it is possible to reduce the size and weight, and to efficiently illuminate a desired irradiation range, and to connect the LED light source body in the vertical direction. Therefore, it is possible to easily change the light distribution and irradiation range by combining LED light source bodies having different light distribution or irradiation directions.
Furthermore, since each spherical light source body 10 is formed in a spherical shape, each of the spherical light source bodies 10 connected in the vertical direction is prevented from shielding light emitted from the other spherical light source bodies 10, thereby improving the illumination efficiency. It becomes possible.

  Further, according to the present embodiment, the spherical light source bodies 10 are connected to each other vertically by interposing the connecting member 40 on the respective center line C or Ca of the spherical light source body 10, and the connecting shafts by the connecting member 40 are respectively connected. For example, a support plate or the like is disposed on both sides of each spherical light source body 10 so that the support plate sandwiches each of the spherical light source bodies 10 from both sides. The light emitted from each spherical light source 10 in the lateral direction (horizontal direction) is not shielded by the support plate, and is irradiated in any direction around the connecting axis. It becomes possible.

In addition, according to the present embodiment, since each of the spherical light source bodies 10 can be rotated around the connecting axis, the irradiation direction (horizontal angle direction) of each spherical light source body 10 can be arbitrarily set.
Furthermore, according to this embodiment, since each of the spherical light source bodies 10 is provided with the plurality of insertion portions 30A and 30B, the LED unit is selected according to the insertion portions 30A and 30B into which the convex portions 41 of the connecting member 40 are inserted. The light irradiation direction (vertical angle direction) of 13 can be changed.
And it becomes possible to change arbitrarily the light distribution of the light source part 7 by connecting the several spherical light source bodies 10 from which an irradiation direction differs vertically.

Further, according to the present embodiment, the lead wire 25 of the LED unit 13 is connected to the power supply device 5 housed in the main body portion 4 through the inside of the spherical light source body 10, so that the lead wire 25 may be exposed to the outside. There is no loss of aesthetics.
Moreover, since the attachment body 11 of the spherical light source body 10 is separable into hemispherical bodies 11A and 11B, when the insertion portions 30A and 30B for inserting the connecting member 40 are changed, the changed insertion portions 30A and 30B are changed. The lead wire 25 can be easily reinserted.

  Moreover, according to this embodiment, since the attachment body 11 was formed from the high thermal conductivity material and the plurality of heat radiation fins 15 were integrally formed on the surface, the heat radiation of the LED unit 13 was efficiently performed.

The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied within the scope of the present invention.
For example, in the embodiment described above, the connecting member 40 having the upper and lower connecting tubular convex portions 41 is disposed between the spherical light source bodies 10, and the spherical light source body 10 is inserted into the connecting member 40. The case where it connects is illustrated.
On the other hand, as shown in FIG. 9, a connecting shaft 45 that vertically passes through the plurality of spherical light source bodies 10 is provided in the main body portion 4, and the spherical light source body 10 is passed through the connecting shaft 45 and connected vertically. It is good also as a structure.
In the embodiment described above, the spherical light source body 10 is configured by attaching the two LED units 13 to the spherical attachment body 11. However, the number of LED units 13 to be attached may be one, or three or more. There may be.
Furthermore, the light source unit 7 may be configured by arranging spherical light source bodies 10 having different numbers of LED units 13 in the vertical direction.
