Description

Technical Field

[0001] The present invention relates to a navigation signal lamp, and more particularly to a navigation signal lamp system integrated with a ship flagpole integrally. Background Art

[0002] The conventional navigation lights are large in external dimensions. Platform brackets are welded on the metal bow and stern flagpoles and fixed to the platform by bolts. In this way, the welding cost and labor cost are very high. Moreover, after welding, spraying protection is required. All cables are exposed and the wiring is messy. Then, a platform is welded and extended in the middle part of the flagpole. The existing conventional navigation lights have the following disadvantages: First, they are very difficult to process. Second, it is very difficult to ensure the level of the platform after welding. Third, when the flagpole is laid down, it is very difficult to lay it flat, and it is easy to crush the lamps, making maintenance very difficult.

[0003] In addition, the existing conventional navigation lights do not consider the structural design for radar stealth, and are easily detected by radar. Moreover, all lamps and the flagpole form a beam structure. After being affected by sea waves and wind, the flagpole is subjected to large forces, there is stress concentration, and there are potential safety hazards. Although there are also individual flagpole lamps that use fixed holes and the housing is riveted or screwed to the metal flagpole at present, this requires opening multiple installation holes on the flagpole, and such lamps can only be installed on metal flagpoles.

[0004] The future trend is that carbon fiber flagpoles have the advantages of light weight, stealth, corrosion resistance, etc., and gradually replace traditional metal flagpoles, becoming an important development direction for modern ships. Therefore, this navigation signal lamp system just meets this trend, while other flagpole lights still cannot meet it. Summary of the Invention

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] The navigation signal lamp system provided by the present invention adopts a flagpole with a hollow structure. Preferably, the metal flagpole is changed to a carbon fiber material and is hollow inside, saving the manufacturing cost of the ship, reducing the weight, and shortening the processing time. In order to increase the strength of the position for installing the lamps on the flagpole, an anchor lamp installation platform 12 made of stainless steel is reinforced at the top of the flagpole 8, and a metal hoop 10 made of stainless steel is used to reinforce each lamp installation position in the middle of the flagpole 8. The lamps are installed on the flagpole 8 by clamping with a hoop, which will not damage the strength of the flagpole. According to the GJB4000-2000 standard, it is stipulated that the bow flagpole is vertically installed on the deck, as Figure 1 shown; the stern flagpole is installed on the deck at an inclination of 15°, as Figure 2 shown.

[0047] The navigation signal lamp system of the present invention adopts a curved surface and other external shapes, without structures such as straight walls and straight dihedral angles that are prone to electromagnetic scattering. The connection part adopts a curved surface arc transition, and the overall shape of the lamp is small. Thus, a conformal integration design is carried out with the bow flagpole and stern flagpole of the ship. While reducing the scattering value of the lamp itself, the coupling between the lamp and the bow flagpole and stern flagpole is also reduced to the lowest level. All the cable inlets are hidden inside the hollow flagpole, thereby greatly reducing the RCS value (radar cross section) of the ship.

[0048] Conventional navigation signal lamps all have an integrated structure of a light source module, an LED driving device, and a lamp structural member. The disadvantages are large size, and when replacing internal components, one needs to climb onto the mast, and the disassembly and assembly during aerial work are troublesome. Moreover, with the passage of time, the conventional LED light source will gradually experience light decay. When the light decay reaches a certain level and the light intensity is lower than the standard requirement, it will not be able to meet requirements such as visibility distance, thus making the navigation of the ship unsafe.

[0049] The navigation signal lamp system of the present invention adopts a split type of LED driving device and lamp light source module. The LED driving device is integrated inside the driving power supply box, and the driving power supply box is installed in the cabin under the deck, which is convenient for replacing components and saves working hours and speeds up the process. The driving power supply box is respectively connected to the navigation lamp controller inside the ship, thereby controlling the entire navigation signal lamp system. The light source module is installed in the lamp on the flagpole. Since there is no installation platform bracket protruding from the flagpole, the flagpole can be easily laid down and flattened, realizing the replacement of the light source module inside the lamp. In addition, the present invention adopts a light decay detection technology: a light decay detection board is arranged inside the lamp, and a light detection sensor is arranged on the light decay detection board. The light detection sensor is connected in parallel to the light source module to work. When it detects that the actual light intensity is less than the minimum light intensity required by the standard, it feeds back to the MCU of the LED driving device for judgment and cuts off the power relay. At this time, the light source module can be replaced. The principle is as Figure 3 shown.

[0050] There are combined flagpole lamps on the market at present, which are said to reduce the number of lamps and installations, but there are great drawbacks, that is, the lamps cannot be lit simultaneously, otherwise there will be mixed light and it will not play the role of indicating the navigation signal of the ship. According to the International Regulations for Preventing Collisions at Sea, 1972, the vertical installation distance between different lamps needs to be greater than 2m. The installation distances of the navigation signal lamp system of the present invention are all greater than 2m, and there will be no mixed light, which will not cause misjudgment of other ships and lead to accidents.

[0051] Lamps are installed on the bow flagpole of the present invention: bow anchor lamp 1, first supply signal lamp 2, bow flagpole lamp 3, and foremast lamp 4; realizing different light emission angles and different light emission colors, all integrated on a flagpole 8. The force application points of the entire lamp are all on the vertical bisector of the flagpole, ensuring reliable and firm installation, as Figure 4 shown.

[0052] On the stern flagpole of the present invention (the stern flagpole is inclined backward on the ship, but it is necessary to ensure that the light-emitting surface is still horizontal at 0°), lamps are installed: the stern anchor light 5, the second supply signal light 6, the stern light (towing light) 7, and the lower navigation light 9; different light-emitting angles and different light-emitting colors are realized and integrated on a single flagpole 8. It covers all the light signals required for ship navigation. All the force points of the lamps are on the vertical bisector of the flagpole, ensuring reliable and firm installation. As Figure 13 shown.

[0053] Installation positions of the bow anchor light 1 and the stern anchor light 5: When the ship is at anchor or aground, a white light emitting 360 degrees needs to be displayed at the most visible place, so they are arranged at the top of the flagpole.

[0054] The first supply signal light 2 and the second supply signal light 6: When the ship is replenishing supplies, since the ship speed slows down to avoid the risk of collision, these lights will be lit to indicate other ships; they emit red light of 360 degrees. In order to avoid light mixing with other lights of different colors, the installation distance must be greater than 2 meters.

[0055] The bow flagpole light 3: emits white light with a 10mm light-emitting circular hole, and the light emission is towards the stern of the ship, providing a positioning center point for the following ship body, so as to maintain the relative position.

[0056] The foremast light 4: emits white light above the center line of the bow, and displays continuous light within a 225-degree horizontal arc for observing other ships.

[0057] The lower navigation light 9: has a horizontal light-emitting angle of 10 degrees. It can be used for other following ships to identify and judge the course and position of this ship, and keep the navigation tracks of the entire ship group consistent.

[0058] At the bottom of the bow and stern flagpoles of the present invention, a driving power supply box will be configured, which integrates the LED control devices of each lamp and supplies power to the lamps. The driving power supply box is connected to the navigation light controller in the ship's cab, and each lamp can be switched at any time. This ensures reliable and stable navigation. At the same time, a wire passing hole is opened at the top or side of the flagpole for the lamp cables to pass through the hollow flagpole interior and connect to the internal wiring terminals of the driving power supply box, thereby hiding the cables and achieving refined design. All lamps are installed by hoop mounting, fitting closely with the flagpole and connecting naturally.

[0059] The following details the specific structures and installation methods of the main lamps of the present invention.

[0060] I. Structure of the bow anchor light

[0061] Please continue to refer to Figure 5, the bow anchor light 1 of the present invention mainly consists of an anchor light mounting platform 12, a first upper cover 101, a first lamp cover 102, a first light source module 103, a first housing 104, a first radiator 105, a bottom cover 106, a metal anti-bending cable connector 11, various gaskets and various fasteners (such as: lamp cover gasket 107, bottom cover gasket 108, screws).

[0062] The first upper cover 101, the first light source module 103, the first lamp cover 102, the lamp cover gasket 107, and the first housing 104 are fixed to the upper and lower ends of the first radiator 105 by two M10 countersunk head screws. The metal anti-bending cable connector 11 is screwed into the bottom cover 106. The bottom cover 106 has a groove, and a gasket is placed in the groove. Then, the bottom cover 106 is fixed to the first housing 104 with three screws to achieve an IP66 waterproof structure. The entire lamp is fixed to the bow anchor light mounting platform with six screws.

[0063] II. The first supply signal lamp

[0064] Currently, there is no supply signal navigation lamp installed on the flagpole on the market. The conventional navigation lamps have large external dimensions, and platform brackets are welded on the metal bow and stern flagpoles and fixed to the platform by bolts. In this way, the welding cost and labor cost are very high, and after welding, spraying protection is still required. All the cables are exposed outside, the wiring is messy, and the structural design for radar stealth is not considered, making it easy to be detected by radar.

[0065] Currently, all conventional supply signal lamps with a luminous angle of 360° use a whole-ring transparent PC lamp cover as the luminous surface, which increases the area that needs to be waterproofed and there is a phenomenon of water leakage and water vapor ingress. Moreover, the vertical light arc angle is large, which will shine into the cab at night and affect the driver's night driving. And for a whole-ring lamp, it is necessary to first put the lamp into the middle of the flagpole for installation during the production of the flagpole, and it cannot be disassembled later.

[0066] Please continue to refer to Figure 6 , the first supply signal lamp 2 of the present invention is completely different from the conventional ones. It adopts a modular design and is divided into two independent modules. Each independent module consists of a second upper cover 201, a second housing 204, a second light source assembly 203, a first upper cover gasket 206, a second lamp cover 202, a first lamp cover pressing plate 207, and fixing screws 16. The two independent modules are connected by plug-in terminals in the middle, and then the two independent modules are locked and clamped to the middle of the flagpole 8 by fixing screws 16. And a double waterproof structure is provided between the two independent modules: a radial O-ring 15 and a flat washer 14, as Figure 8 shown, and an anti-detachment device extends from one side of the housing. It can install a horizontally arranged metal anti-bending cable connector 11 and prevent the lamp from sliding down. This supply signal lamp occupies extremely little space and is very difficult to be detected by radar.

[0067] The light-emitting surface of the supply signal lamp is six evenly distributed small square light outlets. Each light outlet is formed by a light source board, a lamp shade, a lamp shade pressing plate and an O-ring to form a sealed waterproof structure (that is, the second light source assembly 203 has three light source boards, and the numbers of the second lamp shade 202 and the first lamp shade pressing plate 207 are both three). The light-emitting angle can also reach 360°, and the vertical light arc angle of the light outlet is small, without other stray light generated, and will not shine into the cab.

[0068] III. Bow flagpole lamp

[0069] Currently, there are also similar flagpole lamps, but they use the fixed hole method, and the housing is riveted or screwed to the flagpole. It is necessary to drill a large number of holes in the flagpole, and this type of lamp can only be installed on a metal flagpole, which will damage the strength of the flagpole and pose a hidden danger.

[0070] Please refer to Figure 9 and Figure 10 , the bow flagpole lamp 3 of the present invention mainly includes a first front cover 301, a third lamp shade 302, a third light source module 303, a third housing 304, a lens 305, a first front cover gasket 306 and a second lamp shade pressing plate 307; the flagpole conformal bow flagpole lamp adds a metal collar 10 on the flagpole to increase the strength of the carbon fiber flagpole, and is clamped to the metal collar 10 by a hoop. And a anti-drop device protrudes from one side of the housing, which can install a metal anti-bending cable joint 11 and prevent the lamp from sliding down. A labyrinth waterproof structure is adopted between the first front cover 301 and the third housing 304.

[0071] IV. Foremast lamp

[0072] Currently, there is no foremast lamp navigation signal lamp installed on a carbon fiber flagpole by a hoop on the market. The conventional navigation lamp has a large external dimension, and a platform bracket is welded on the metal bow and stern flagpoles and fixed to the platform by bolts. In this way, the welding cost and labor cost are very high, and after welding, spraying protection is still required. All the cables are exposed outside, the wiring is messy, and the structural design for radar stealth is not considered, so it is easy to be detected by radar. Moreover, all the lamps and the flagpole are a beam structure. After being affected by waves and wind, the flagpole is subjected to large forces, there is stress concentration, and there will be potential safety hazards.

[0073] Currently, the conventional foremast lamp has a light-emitting angle of 225°. The light-emitting surface uses a whole annular transparent lamp shade plus an internal black light-shielding plate to achieve the light-emitting angle, resulting in an increase in the area that needs to be waterproofed, and there is a phenomenon of water leakage and water vapor ingress. And the vertical light arc angle is large, which will shine into the cab at night and affect the driver's night driving.

[0074] This flagpole conformal foremast light is completely different from the conventional one. It uses an entire cylindrical lampshade, and the light-emitting angle is achieved by adding a light-shielding plate. The problem is that for the cylindrical lampshade, the protruding arc surface area can be seen from the ship's cab, and the glaring afterglow will affect the safe driving of the driver. The light-emitting surface of the foremast light 4 of the present invention is three evenly distributed small rectangular light-emitting ports. Each light-emitting port is formed into a sealed waterproof structure by 1 light source board, 1 lampshade, 1 lampshade pressing plate and an O-ring as Figure 11 shown, and by changing the light-emitting position of the light source and the size of the lampshade pressing plate, the light-emitting angle can also reach 225°. Moreover, the vertical light arc angle of the light-emitting port is small, no other afterglow is generated, and it will not shine on the deck, thus affecting the judgment of the driver.

[0075] Please refer to Figure 11 and Figure 12 , the foremast light 4 of the present invention mainly includes a third upper cover 401, a fourth lampshade 402, a fourth light source module 403, a fourth housing 404, a fourth radiator 405, a second upper cover gasket 406 and a third lampshade pressing plate 407.

[0076] This flagpole conformal foremast light adds a metal retaining ring 10 on the flagpole to increase the strength of the carbon fiber flagpole, and uses a hoop type to clamp onto the metal retaining ring 10. And a anti-detachment device extends from one side of the housing, which can install a metal anti-bending cable joint 11 and prevent the lamp from sliding down. A labyrinth waterproof structure is adopted between the third upper cover 401 and the fourth housing 404. This foremast light is perfectly integrated with the flagpole, occupies extremely little space and is very difficult to be detected by radar.

[0077] V. Stern anchor light

[0078] The structure of the stern anchor light 5 is the same as that of the bow anchor light 1 above. The anchor light installation platform 12 conforms to the inclination angle of the stern flagpole, and a fixed horizontal installation platform is made to ensure that the horizontal light-emitting angle of the lamp is 0 degree. The installation methods of the stern anchor light 5 and the bow anchor light 1 are the same. It will not be elaborated here, please refer to the above.

[0079] VI. Second supply signal lamp

[0080] For the lamps on the conventional stern flagpole inclined at 15 degrees, the flagpole is made of metal material. Then, in the middle part of the flagpole, a platform is welded and extended. First, it is very difficult to process. Second, it is very difficult to ensure the level of the platform after welding. Third, when the flagpole is laid down, it is very difficult to lay it flat and it is easy to crush the lamp, making maintenance very difficult. Moreover, all lamps and the flagpole are a beam structure. After being affected by sea waves and wind, the flagpole is subjected to large forces, there is stress concentration, and there will be potential safety hazards.

[0081] Currently, there is no such type of lamp installed on a 15-degree inclined stern flagpole in the market. After the replenishment signal lamp meets the inclined hoop-mounted installation, the horizontal luminous angle can still meet the requirements of the GB3028-2012 "Marine Electric Signal Lamps" standard. And it occupies a small space and is not easily detected by radar.

[0082] The existing problems and solutions of the second replenishment signal lamp 6 on the stern flagpole are the same as those of the first replenishment signal lamp 2 on the bow flagpole above, mainly including the fourth upper cover 601, the fifth lamp cover 602, the fifth light source module 603, the fifth housing 604, the fifth radiator 605, the third upper cover gasket 606, and the fourth lamp cover pressing plate 607, as Figure 14 and 15 shown; the specific structure will not be elaborated here, see the above for details.

[0083] VII. Stern Light (Towing Light)

[0084] For the lamps on the conventional 15-degree inclined stern flagpole, the flagpole is made of metal material. Then, in the middle part of the flagpole, a platform is welded and extended. Firstly, it is very difficult to process. Secondly, it is very difficult to ensure the horizontality of the platform after welding. Thirdly, when the flagpole is laid down, it is very difficult to be laid flat and is easy to crush the lamp, making maintenance very difficult. Moreover, all the lamps and the flagpole are in a beam structure. After being affected by sea waves and wind, the flagpole is under great stress, there is stress concentration, and there will be potential safety hazards.

[0085] There are also similar flagpole lamps in the market currently, but they adopt the fixed-hole method, and the housing is riveted or screwed to the flagpole. It is necessary to drill multiple holes in the flagpole, and this type of lamp can only be installed on a metal flagpole, which will damage the strength of the flagpole and there are potential hazards.

[0086] Please refer to Figure 16 and Figure 17 , the stern light 7 of the present invention mainly includes a second front cover 701, a sixth lamp cover 702, a sixth light source module 703, a sixth housing 704, a sixth radiator 705, a second front cover gasket 706, a fifth lamp cover pressing plate 707, a wire clip 708, and a wire collecting plate 709;

[0087] For this stern light (towing light), a metal loop 10 is added to the flagpole to increase the strength of the carbon fiber flagpole, and it is clamped to the metal loop 10 by a hoop method. And on one side of the housing, an anti-drop device is extended, which can not only install a metal anti-bending cable joint 11 but also prevent the lamp from sliding down. A labyrinth waterproof structure is adopted between the second front cover 701 and the sixth housing 704.

[0088] VIII. Lower Track Light

[0089] For the conventional lamp on the 15-degree inclined stern flagpole, the flagpole is made of metal. Then, in the middle part of the flagpole, a platform is welded and extended. Firstly, it is very difficult to process. Secondly, it is very difficult to ensure the level of the platform after welding. Thirdly, when the flagpole is laid down, it is very difficult to lay it flat, and it is easy to crush the lamp, making maintenance extremely difficult. Moreover, all the lamps and the flagpole form a beam structure. After being affected by sea waves and wind, the flagpole is subject to large forces, there is stress concentration, and there will be potential safety hazards.

[0090] Currently, there are also similar flagpole lamps on the market, but they adopt the fixed-hole method, and the housing is riveted or screwed to the flagpole. It is necessary to drill multiple holes in the flagpole, and this type of lamp can only be installed on a metal flagpole, which will damage the strength of the flagpole and pose potential hazards.

[0091] Please refer to Figure 18 and Figure 19 , the lower track lamp 9 of the present invention mainly includes a third front cover 901, a seventh lamp cover 902, a seventh light source module 903, a seventh housing 904, a seventh radiator 905, a third front cover gasket 906, a sixth lamp cover pressing plate 907, a rotary switch 908, a mounting plate 909, and a sealing ring 910.

[0092] For the current conventional lower track lamp, different light intensity switching is achieved by blocking the light source through a mechanical grille structure. This lower track lamp is provided with an electronic knob switch 908 at the bottom of the third front cover 901, which is connected to the seventh light source module 903. By rotating the rotary switch 908 to different gears, different light intensity switching is achieved.

[0093] This lower track lamp adds a metal hoop 10 on the flagpole to increase the strength of the carbon fiber flagpole, and is clamped to the metal hoop 10 by a hoop type. And an anti-detachment device extends from one side of the housing, which can not only install a metal anti-bending cable joint 11, but also prevent the lamp from sliding down. A labyrinth waterproof structure is adopted between the third front cover 901 and the seventh housing 904.

[0094] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be defined by the claims.
