Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a lighting device using solar cells, and more particularly to an outdoor lighting device using a solar cell as a power source,
In particular, the present invention relates to a structure that allows the installation direction of solar cells and the installation direction of lighting equipment to be set independently.

[Prior art]

Conventionally, lighting devices using solar cells have generally had a solar panel mounted on the top of a pole at an angle, and a lighting fixture provided slightly below the top of the pole.

Typically, solar panels are oriented toward the south, while the orientation of lighting fixtures varies depending on the location of use. However, in conventional lighting devices that utilize solar cells, the direction of the solar panel and the lighting equipment are fixed, and the actual situation does not take into account the above-mentioned problems in the direction of both. I felt like it wasn't being done. Some of them used prismatic poles, perhaps from a design standpoint, creating an aspect that made it increasingly difficult to explain this requirement.

Recently, solar cells have been developed in which a lighting fixture is attached to a part of the periphery of the solar panel, and the solar panel is attached to the upper end of a pole so that it can freely rotate about a direction perpendicular to the surface of the solar panel. An idea for a lighting device (Utility Model Publication No. 106802/1983) was published, but even in this, the inclination of the solar panel could not be freely adjusted to point south, and the direction of the lighting equipment was different. This was insufficient in that it was related to the direction of the solar cell.

[Summary of the invention]

The present invention not only makes it possible to independently set the installation direction of the solar panel and lighting equipment in an outdoor light that uses a solar panel at the top of the pole as a power source, but also allows the tilt of the solar panel to be adjusted on-site during installation. With the aim of making it possible, there is a joint at the top of the pole above the lighting fixture that can rotate around the center axis of the pole, and above that a joint that can rotate around the center axis of the pole. The present invention is characterized in that a joint portion is provided, and the solar cell panel is mounted at an angle with respect to the tilted axis.

[Embodiments of the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the solar battery-based lighting device of the present invention will be described in more detail with reference to preferred embodiments shown in the accompanying drawings.

In this embodiment, as shown in FIG. 1, a lighting fixture 4 is attached via an arm 3 to the vicinity of the upper end 21 of a pole 2 made of a round pipe erected on the ground 1. A pole socket 5 made of a round pipe having a smaller diameter than the pole 2 is fixedly attached to the upper end 21 of the pole 2, and projects upward from the upper end of the pole. An elbow-shaped member 6 is fitted into the pole socket 5.

That is, this elbow-shaped member 6 is made up of a lower cylindrical part 61 and an upper cylindrical part 62 having an axis bent with respect to the axis of the lower cylindrical part, and is rotatable into the inside of the lower cylindrical part 61. It is attached to the upper end 21 of the pole via the pole socket 5 inserted into the pole. The cylindrical portion 6 above this elbow-shaped member 6
A socket 7 made of a round pipe having a diameter smaller than that of the elbow-shaped member is attached and fixed coaxially with the cylindrical portion 62 and protrudes from the end surface thereof.

The solar cell panel 9 has solar cells arranged on its front surface 91, and an obliquely erected cylindrical portion 8 attached to its back surface 92. This solar cell panel 9 is attached to the elbow-shaped member 6 by rotatably inserting the socket 7 at the upper end 63 of the elbow-shaped member 6 into the cylindrical portion 8 provided on the back surface 92 thereof.

Furthermore, reference numeral 10 denotes an electrical equipment box that houses a storage battery and a lighting device for a light source, and is provided along the base of the pole 2. Further, 12 indicates a light source housed within the lighting fixture 4.

FIG. 2 shows the embodiment shown in FIG.
This is a diagram showing a state in which the cylindrical portion 8 provided diagonally on the back surface 92 of the solar cell panel 9 has been rotated 180 degrees along the socket 7, which is the rotation axis, and FIG. 6 is a diagram in which the orientation of the solar cell panel 9 is changed by rotating the solar panel 6 by 180 degrees along the pole socket 5, which is its rotation axis.

For outdoor lights that use a solar panel at the top of a pole as a power source, the optimal inclination angle and direction should be selected depending on the latitude and topography of the installation location, the arrangement of nearby high-rise buildings, etc. On the other hand, the installation direction of the lighting equipment must be selected depending on the purpose of installation and the object to be illuminated, regardless of the direction of the solar panel 9. On the other hand, according to the solar battery-based lighting device of the above embodiment, when the pole 2 is erected, the installation direction of the lighting fixture 4 is determined according to its purpose and the object to be illuminated, and the inclination of the solar battery panel 9 is adjusted to the cylindrical part. By rotating the elbow member 8 relative to the socket 7 to obtain the optimum direction, and then further rotating the elbow member 6 relative to the pole 2 around the pole socket 5 to obtain the optimum direction, all of the above conditions can be met. A satisfactory installation state can be completed.

Although not shown, setscrews may be provided in the lower part 61 and the cylindrical part 8 of the elbow-shaped member 6, respectively, if necessary, and tightened to the sockets 5 and 7, respectively, when the installation is completed, so that the posture in the completed state can be adjusted. can be maintained.

〔Effect of the invention〕

As explained above, according to the solar battery-based lighting device of the present invention, the direction and inclination of the solar panel can be adjusted independently and independently from the lighting fixture, so can receive light from
