Description

  The present invention relates to an outdoor lamp installed outdoors.

  2. Description of the Related Art Conventionally, outdoor lamps installed outdoors such as street lamps have been known that include a solar panel that generates power by receiving sunlight (see Patent Document 1).

JP 2003-51208 A

  In the technology described in Patent Document 1, in a street light, from the viewpoint of protecting the battery from flooding during direct flooding or heavy rain and direct sunlight, a battery for illumination is attached in the vicinity of the illumination light that is attached to the upper part of the column. A solar panel is attached to the upper end of the column so that the direction of the solar panel can be changed.

  However, in Patent Document 1, although the occurrence of problems caused by flooding or heavy rain and problems caused by direct sunlight are suppressed, the battery is arranged at a high place in the vicinity of the illuminating lamp. A new problem arises that maintenance that is normally performed becomes work at a high place.

  In addition, collecting and attaching accessories such as an illumination lamp, a solar panel, and a battery (battery box) to the top of the column has a problem that the column itself has a biased center of gravity and is unstable.

  An object of the present invention has been made in view of the above circumstances, and can provide an outdoor lamp that can easily perform maintenance such as inspection and replacement of the battery of the lighting unit and can stably install the support column. It is to provide.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the present invention provides:
In outdoor lights installed outdoors,
Provided with a support column in the form of a hollow having a solar panel that generates power by receiving sunlight and an illumination unit that lights up using the power generated by the solar panel,
The lower end of the column is fixed to the upper part of a hollow box-type foundation box fixed to the ground or other installation surface, and the column is erected on the foundation box. A battery for charging the power generated by the panel and supplying the charged power to the lighting unit is accommodated, and the battery and the solar panel and the lighting unit are connected by wiring passing through the inside of the hollow column. It is characterized by that.

  According to this, a column is erected on a foundation box in the form of a hollow box, and the battery (with a controller if necessary) is used in the foundation box using the internal space of the foundation box through which the column does not penetrate. Is housed (stored), the center of gravity does not increase as compared with a mode in which a battery having an appropriate weight is provided in the upper part or middle part of the support column, and a stable battery or the like can be installed. In addition, maintenance such as inspection and replacement of the battery (and the controller as necessary) can be easily performed. And after ensuring storage space, such as a battery, a support | pillar can be stably supported on the foundation box. Furthermore, since a battery etc. are accommodated in a foundation box and wiring is passed from the inside of a support | pillar, a battery etc. can be protected from the flooding and direct sunlight by the time of flood or heavy rain.

  In addition, an illuminance sensor that detects ambient brightness may be provided in the solar panel, the illumination unit, or the support column, and the illumination unit may be turned on or off based on the illuminance detected by the illuminance sensor.

  In addition, a flange portion protruding outward for fixing to the installation surface is formed on the bottom portion of the hollow box shape of the foundation box, and in this case, for example, fixing to the installation surface via the flange portion is performed. It can be easily performed using an anchor bolt or the like.

  In addition to the battery, a controller for controlling charging from the solar panel to the battery and lighting / extinguishing of the illumination unit is housed in the hollow box-shaped foundation box. Can be centrally managed in the basic box.

  Further, the lower end of the support column is attached to the upper surface of the hollow box shape of the foundation box, and an opening portion in which a removable lid is fixedly arranged is formed on the side wall of the foundation box. By opening the lid, it is possible to easily check, repair, replace, etc. the battery in the foundation box and the necessary controller.

  Further, the support column has a cylindrical shape, is bent from an upright portion rising from the foundation box, and includes a bent portion having the illumination portion at the bent tip region, and the solar panel is disposed above the bent portion. In this way, the lighting part can be integrated with the bent part to create a smart form, and since the solar panel is above the bent part, the light reception of the solar panel is not hindered by the lighting part, Moreover, since the downward illumination by the illumination unit is not obstructed by the solar panel, it is possible to maximize the functions of both the solar panel and the illumination unit.

  Further, the foundation box is formed in a taper shape in which the cross-sectional area of the hollow portion gradually increases from the upper part to the lower part, so that the fixing of the foundation box to the installation surface such as the ground is stable, and as a result, on the foundation box The stability of the pillars erected on the floor also increases.

  Further, in the foundation box, there are provided a fixing portion for fixing the battery, and further, a fixing portion for fixing the controller as required. In this way, vibration due to passing of the vehicle, vibration due to wind or earthquake, etc. Even the battery and controller are held stably in the foundation box.

  In addition, the solar panel is fixed to the column so that the angle can be adjusted, and in this way, the solar panel is adjusted to an angle at which sunlight can be received most efficiently according to the place where the column is installed. , Power generation efficiency can be increased.

  Here, as the illumination unit, an illumination unit using a light emitting diode is preferable, and incandescent lamps, fluorescent lamps, mercury lamps, and the like can be used.

  According to the outdoor light of the present invention, for example, it can be set so that the illumination unit is turned off during the daytime, the solar panel generates power, and the illumination unit is automatically turned on at night, simply by being installed on the road or in the park. . And if a light emitting diode is used for an illumination part, power consumption will become small and the lighting time at night can be extended. Furthermore, since it is an independent power generation type and does not require wiring work, it does not require any special maintenance, so that it can be installed anywhere freely in the daytime and has versatility.
