  As shown in Patent Document 1 described above, in the field related to street lamps, many techniques for obtaining electric power using solar power generation by a solar panel have been proposed. Furthermore, it is basically considered that it has a complete mechanism that sends electricity generated by solar power generation to the light source side without requiring a commercial power source. The part excluding the column part) is configured as a group of lamps that contain solar panels, batteries, and light sources, etc., so that lighting fixtures for street lamps that are compact and have an exterior appearance are now required. It is coming. If a lighting fixture with a compact solar panel, power supply unit, light source unit, etc. is attached to, for example, an existing column, it can be used to provide a street light with a very low environmental impact through energy saving using sunlight. It is considered.

  By the way, in street lamps that use electricity obtained by solar power generation, a storage battery that receives and stores electricity generated by the solar panel is an important power source, and maintains the function of lighting equipment. Above, it is desirable to be able to inspect the presence or absence of a decrease in the capacity of the storage battery as necessary. Of course, it is desirable that not only the storage battery but also various electrical components used as lighting equipment can be inspected and replaced.

  However, having a structure that can be easily inspected is difficult to incorporate into a lighting apparatus using photovoltaic power generation that is desired to be integrated and compact. That is, if the solar panel, the power supply unit, the light source unit, etc. are combined into a single lighting fixture housing that is a closed space, the inspection operation for the storage battery alone, for example, It becomes necessary to insert the terminal of the inspection device held by the inspector from a part deep inside the housing, and even inspection items that only need to be visually confirmed cannot be easily performed.

  On the other hand, for storage batteries used in the power supply unit, whether the state of the power supply unit can be grasped by obtaining and examining changes in the charge amount and discharge amount of the storage battery, and whether the specified performance is being demonstrated in terms of storage battery performance You can judge whether or not. If the operation status of the storage battery is acquired from the power supply unit side in the lighting fixture and can be transmitted as information to the external device, it becomes easy to grasp the status of the main device in a remote state.

  However, even if a device that performs transmission and reception is incorporated in the support shown in Patent Document 2 described above, the lighting fixture cannot be made compact. As described above, even in a technique in which a device capable of transmitting and receiving information is simply arranged on a streetlight column, it is not a proposal that can be used to make the lighting fixture integrated and compact.

  Therefore, in view of the above circumstances, the present invention has an inspection for a power supply unit, etc., with a lighting fixture for a street light that uses a storage battery that stores electricity from photovoltaic power generation as a power supply while integrally including necessary components as the lighting fixture. An object of the present invention is to make it easy to perform, and an object of the present invention is to provide a lighting device for street lamps that is easy to manage and maintain without losing its compact form.

The outer surface of the dome-shaped cover 12 includes an antifouling material containing a substance that exhibits high dirt removal properties by photocatalysis. The agent is applied.

  Thus, in this lighting fixture 1, since the solar panel 11 is utilized as one part of the canopy 6, the canopy 6 is opened without removing the solar panel 11 separately during maintenance of the power supply unit 3 and the light source unit 4. With the simple operation, the upper surface of the lamp body 5 is greatly opened, and visual confirmation with respect to the power supply unit 3 and the light source unit 4 is easy, and operations such as attachment and removal to the power supply unit 3 and the light source unit 4 are also easy. Become. Since the canopy 6 is configured to cover the storage space 2a of the lamp body case 2 in which the power supply unit 3 and the light source unit 4 are disposed so as to be openable and closable, the power supply unit 3 and the light source unit are disposed below the solar panel 11. 4 and, of course, other electric parts (not shown) are also arranged in the storage space 2a as installation locations.

  In the said lighting fixture 1, the device which enabled it to acquire the operation | movement condition of the power supply part 3 as information as non-contact is given. To explain this, first, the lamp body case 2 includes a transmission / reception unit 13, and the transmission / reception unit 13 is, for example, a wireless LAN represented by Wi-Fi (brand name of communication standards). Based on a communication standard such as a system, information is exchanged by executing mutual communication with an external transmission / reception device having a communication means, which is composed of a mobile phone or a notebook personal computer.

  The control unit 14 provided inside the lamp body case 2 is connected to the power supply unit 3 and constantly acquires information on the operation status of the power supply unit from the power supply unit 3. The information on the power supply unit operation status is information generated from a sensor attached to the storage battery, and includes power generation amount, discharge amount, battery remaining amount data, environmental data, number of cycles, and error code. These are always acquired as power supply unit operation status information, and stored and managed as power supply unit information in association with date / time information from a timer (based on GPS time data) of the control unit 14 itself. .
