Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a pole type lighting device.
[0002]
[Prior art]
Conventionally, as shown in Patent Document 1, a lamp light spot notification function of a luminaire and confirmation at the time of a power failure are arranged at a position for receiving light entering from a light source, and the other end of the optical fiber is disposed at the other end. Connected to a control device provided near the lower end of the pole, turned on the LED in response to a signal from the light receiving unit, and inspected by visually checking the LED, the light source could be turned on even in the daytime There is something.
Further, for example, a foot lamp that is provided with an LED is generally configured separately from an illumination lamp as shown in Patent Document 2.

[Problems to be solved by the invention]
However, according to the above-described prior art, it is necessary to configure a lamp incongruity notification function of a lighting fixture or a dedicated foot lamp, which has a drawback in that the configuration is diverse and the cost is high. In addition, when a lighting fixture is configured with a point detection function or a light compensation function at the time of a power failure, it is necessary to prepare a lighting fixture of another configuration in a configuration in which those functions are not required.
[0005]
The present invention has been made in view of the above contents, and can be used for a lamp astigmatism detection function, a light compensation function at the time of a power failure, and a function as a foot lamp, and can easily detect a lamp astigmatism in an existing pole. It is an object of the present invention to provide a pole-type lighting device that can be added with a function or a function as a foot lamp and can be configured at a relatively low cost.
[0006]
According to the first aspect of the present invention, an illuminating device is supported above the pole, an inspection port is provided near the lower end of the pole, an open / close lid is supported on the inspection port so that the opening / closing lid can be opened and closed. A control circuit is provided, and an auxiliary lamp is provided on the inspection lid so as to be visible from the outside. Further, the auxiliary lamp is turned on when the light source mounted on the illuminator becomes inconspicuous, or when the light source is turned off or dimmed at midnight. In addition to the lighting control circuit, a battery is arranged inside the inspection lid, and when the power supply fails, the auxiliary lamp is turned on using the battery as a power source .
[0012]
According to the above-mentioned pole type illumination device, the lamp astigmatism detection function, the light compensation function at the time of power failure, and the function as a foot lamp can be used together and can be configured with a simple structure.
In addition, it is possible to easily add a lamp astigmatism detection function, a light compensation function during a power failure, and a function as a foot lamp to an existing pole having an inspection lid. In addition, by providing a timer function to the control circuit, the light source is turned off or dimmed during periods when high illuminance is not necessary, such as at midnight, and the auxiliary lamp is turned on to save energy and minimize brightness. It can be secured.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to FIGS. 1 to 4, 1 Paul comprising supporting the illuminating device 2 to the desired position, as the illumination device 2 shown in FIG. 3, for example, it is supported near the top of the pole. The illuminator 2 may be supported near the middle of the pole in addition to the vicinity of the top of the pole, and the illuminance on the irradiated surface may be adjusted. A light source 3 is mounted inside the illuminator 2. For example, a high pressure discharge lamp is used as the light source. Reference numeral 4 denotes an inspection port formed in the vicinity of the lower end of the pole 1, and reference numeral 5 denotes an inspection lid supported by the inspection port so as to be freely opened and closed. The inspection lid 5 is manufactured in the same shape and size as a general lighting pole inspection lid, and can be attached to the general lighting pole without any particular modification. 6 is a control circuit formed by supporting on the inside of the inspection lid 5, are constructed with a timer function. In addition, the control circuit is configured by adding a point detection function and a power failure detection function according to the purpose of use. Reference numeral 7 denotes an auxiliary lamp arranged so as to be visible from the outer surface of the inspection lid 5, and is configured using, for example, an LED. A battery 8 is provided on the inner surface of the inspection lid 5.
[0014]
1 to 4, the light source 3 is controlled by the lighting control circuit 6, and when the control circuit 6 has the astigmatism detection function, the light source 3 is detected to turn on the auxiliary lamp 7 of the inspection lid. Disadvantages are detected from fluctuations in the current value, voltage value, power value, etc. of the power supply.
The auxiliary lamp is configured to function as a foot lamp.
[0015]
In addition, when the light source 3 is controlled by the control circuit 6 and the control circuit 6 has a timer function, the power supply to the lamp of the light source 3 is controlled to be turned off or dimmed at the specified time zone, and at the same time the inspection is performed. The auxiliary lamp 7 on the lid is turned on.
[0016]
The light source 3 is controlled by the control circuit 6. When the control circuit 6 has a light compensation function, a power failure is detected, and the auxiliary lamp 7 of the inspection lid is supplied with power from the battery and turned on.
[0017]
According to the first aspect of the present invention, it is possible to obtain a pole-type illumination device that has a function as an astigmatism detection function, a light compensation function at the time of a power failure, and a function as a footlamp at a low cost. By replacing it with a lid, there is a special effect that can be easily added to the existing pole as a spot detection function, a light compensation function during a power failure, and a function as a footlamp. Also, by turning off the light source or dimming it during times when high illuminance is not necessary, such as late at night, and turning on the auxiliary lamp , it is possible to illuminate the area around the pole with the required brightness while saving energy. There is.
