[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to a lighting device for a ship, which is mounted on an unmanned ship or a non-powered ship and holds a lamp stipulated by law to ensure safety during navigation and berthing.

[0002]

[Prior art]

 Conventionally, towed objects (other than ships) towed by ships, towed ships, ships anchored or on board (hereinafter referred to as ships, etc.) are often unmanned or powered off. To ensure safety, the lights must be raised as required by law. For this reason, the battery power supply and sun switch (optical sensor and optical sensor circuit that drives the optical sensor) required for several days to keep the legal light on are loaded on the ship, etc. Ship lights were installed, incandescent lights were used for the ship lights, and wiring was conducted from the battery power supply to the sun switch and the ship lights. In addition, the lighting and turning off of the ship lights use an optical sensor that detects the surrounding light and darkness. When the optical sensor detects a dark state, that is, when the output of the optical sensor decreases, an exciting current flows and an electromagnetic relay is turned on. The normally open contact is closed, and the lamp is energized from the battery power supply to illuminate. Also, when the optical sensor detects a bright state, the exciting current is cut off, the electromagnetic relay is opened, and an electromagnetic relay circuit is provided to cut off between the battery power supply and the lamp.

[0003]

[Problems to be solved by the invention]

 However, in the above-mentioned conventional method, since an incandescent lamp is used as a ship light, power consumption is drastic, and a large amount, for example, 4 to 8 battery power supplies of about 30 kg is mounted on a ship or the like. Had to be kept. Also, since the battery power supply is heavy, it is not easy to move in ships etc., especially for large vessels etc., it is necessary to raise many ship lights such as port lights, starboard lights, stern lights, etc. The wiring to the installation location was longer. In addition, since the battery power supply, light sensor and ship lights were connected separately, much time and labor was required to maintain the reliability in order to maintain reliability. Also, when the optical sensor detects a bright state, the exciting current of the electromagnetic relay is turned off to open the electromagnetic relay and turn off the boat lamp, so that when the optical sensor or optical sensor circuit breaks down, the output from the optical sensor circuit is lost. Does not appear. Therefore, since the exciting current does not flow, the electromagnetic relay with normally open contacts opens and does not light even when it becomes dark. For this reason, failures are often found after darkening, and there has been a problem that the response to the failures on ships at sea is delayed, which is extremely dangerous. The present invention has been made in view of such circumstances, and provides a ship lighting device that consumes less power, uses a discharge lamp to reduce the size and safety of a battery power source, and can save labor. The purpose is to do.

[0004]

[Means for Solving the Problems]

 The marine lighting device according to the present invention, which meets the above-mentioned object, is driven by a battery power source, an inverter connected to the battery power source, a discharge lamp that is turned on by the output of the inverter, and an output of an optical sensor that detects ambient brightness. The normally closed contact of the electromagnetic relay circuit is connected in series with the lighting circuit of the discharge lamp, and when the surroundings become dark and when the electromagnetic relay circuit including the optical sensor fails, Then, the discharge lamp is driven to be lit through the inverter. As a result, since a discharge lamp such as a fluorescent lamp is used as a ship lamp, the power consumption is extremely low as compared with the case where an incandescent lamp is used, and the battery power supply can be reduced to about one third of the conventional capacity. Also, the normally closed contacts (generally called B contacts) of the electromagnetic relay circuit are connected in series to the lighting circuit of the discharge lamp. Is connected and the discharge lamp is lit, but if the optical sensor or the optical sensor circuit that drives the optical sensor breaks down, the exciting current of the electromagnetic relay circuit is cut off, so the electromagnetic relay is closed and bright. But it is lit.

[0005] In the lighting device for a ship according to the present invention, an electromagnetic relay circuit including a discharge lamp, an inverter and an optical sensor has an integral structure and is housed in the ship lamp. In this case, the wiring between the electromagnetic relay circuit including the discharge lamp, the inverter, and the optical sensor is shortened, the control current and voltage are stable, the reliability is high, and the cost is easy. In the lighting device for a ship according to the present invention, the battery power supply includes a charging device, is separate from the ship light, and is connected to the ship light by a cord. In this case, it is easy to install the lamp at any place, such as a place where it is difficult to carry the battery power, such as a high place such as a mast of a ship or a place protruding like a bow. Since the battery power supply is lightweight and easy to move, it can be installed in a stable place even if it is small near the lamps.
