Description

Technical Field

[0001] The invention relates to a navigation signal light, and in particular to a navigation signal light system integrated with a ship flagpole. Background Art

[0002] Conventional navigation lights are large in size, and are welded to the metal bow and stern flagpoles with platform brackets and fixed to the platform with bolts. This results in high welding and labor costs, and spray coating is required after welding. All cables are exposed, and the wiring is messy. Then, a platform is welded out of the middle of the flagpole. Existing conventional navigation lights have the following disadvantages: first, they are difficult to process, second, it is difficult to ensure the level of the platform after welding, and third, when the flagpole is laid down, it is difficult to lay it flat, which can easily damage the lamp and make maintenance very difficult.

[0003] In addition, the existing conventional navigation lights do not consider the radar stealth structure design, which is easy to be detected by radar, and all the lamps and flagpoles are a beam structure. After being affected by waves and wind, the flagpole is subjected to great stress, which leads to stress concentration and potential safety hazards. Although some flagpole lamps currently use the fixing hole method, the shell is riveted or screwed to the metal flagpole, but this requires opening multiple mounting holes on the flagpole, and such lamps can only be installed on metal flagpoles.

[0004] The future trend is that carbon fiber flagpoles have advantages such as light weight, stealth, and corrosion resistance, and will gradually replace traditional metal flagpoles and become the heavy pressure development direction of modern ships. Therefore, the navigation signal light system just meets this trend, which other flagpole lights still cannot meet. Summary of the invention

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] The navigation signal light system provided by the present invention adopts a flagpole with a hollow structure. It is preferred that the metal flagpole be changed to a carbon fiber material with a hollow interior, so as to save the manufacturing cost of the ship, reduce the weight, and shorten the processing time. In order to increase the strength of the position where the lamp is installed on the flagpole, an anchor light installation platform 12 made of stainless steel is reinforced on the top of the flagpole 8. Each lamp installation position in the middle of the flagpole 8 is reinforced with a metal ring 10 made of stainless steel. The lamp is installed and fixed to the flagpole 8 by clamping. It will not damage the strength of the flagpole. According to the GJB4000-2000 standard, it is stipulated that the bow flagpole is to be installed vertically on the deck. Figure 1 As shown in the figure; the stern flagpole is installed on the deck with an inclination of 15°. Figure 2 shown.

[0021] The navigation signal light system of the present invention adopts a curved surface design, and has no straight walls, straight dihedrals and other structures that are likely to cause electromagnetic scattering. A curved arc transition is adopted at the connection, and the overall shape of the lamp is small; thereby, the lamp is conformally integrated with the bow flagpole and the stern flagpole of the ship. While reducing the scattering value of the lamp itself, the coupling between the lamp and the bow flagpole and the stern flagpole is also reduced to a minimum, and all cable input lines are hidden inside the hollow flagpole, thereby greatly reducing the RCS value (radar cross section) of the ship.

[0022] Conventional navigation signal lights are all light source modules, LED drive devices, and the lighting structure is integrated; the disadvantage is that the size is large, and the internal components need to be replaced by climbing up the mast, and the aerial disassembly and assembly are troublesome. In addition, the conventional LED light source will gradually decay over time. When the light decays to a certain extent and the light intensity is lower than the standard requirements, it cannot meet the requirements of visibility distance, making the ship's navigation unsafe.

[0023] The navigation signal light system of the present invention adopts a split type LED driving device and a lamp light source module. The LED driving device is integrated inside the driving power box, and the driving power box is installed in the cabin under the deck, which is convenient for replacing components, saving man-hours and speeding up the process; the driving power boxes are respectively connected to the navigation light controllers inside the ship, so as to control the entire navigation signal light system. The light source module is installed in the lamp on the flagpole. Since the flagpole does not have an installation platform bracket extending out, the flagpole can be laid down and flat relatively easily to achieve the replacement of the light source module in the lamp. In addition, the present invention adopts light decay detection technology: a light decay detection board is provided inside the lamp, and a light detection sensor is provided on the light decay detection board. The light detection sensor is connected in parallel to the light source module to work. When it is detected that the actual light intensity is less than the minimum light intensity required by the standard, it is fed 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 follows: Figure 3 shown.

[0024] There are combined flagpole lamps on the market, which are said to reduce the number of lamps and installation, but there is a big disadvantage, that is, the lamps cannot be lit at the same time, otherwise the light will be mixed and the function of indicating the navigation signal of the ship will not be achieved. According to the 1972 International Regulations for Preventing Collisions at Sea, the vertical installation distance of different lamps needs to be greater than 2m. The installation distance of the navigation signal light system of the present invention is greater than 2m, and there will be no light mixing, which will affect the misjudgment of other ships and cause accidents.

[0025] The invention installs lamps on the bow flagpole: bow anchor light 1, first supply signal light 2, bow flagpole light 3, front mast light 4; different luminous angles and different luminous colors are realized, and they are assembled on a flagpole 8. The stress points of the entire lamp are on the mid-vertical line of the flagpole, which ensures reliable and firm installation. Figure 4 shown.

[0026] The stern flagpole of the present invention is installed with lamps: stern anchor light 5, second supply signal light 6, stern light (tow light) 7, lower track light 9; different luminous angles and different luminous colors are realized and gathered on a flagpole 8. All the light signals required for ship navigation are covered. The stress points of the entire lamp are on the mid-vertical line of the flagpole, ensuring reliable and firm installation. Fig.13 shown.

[0027] Installation position of bow anchor light 1 and stern anchor light 5: When the ship is anchored or stranded, it is necessary to display 360-degree luminous white light in the most visible place, so it is arranged at the top of the flagpole.

[0028] The first replenishment signal light 2 and the second replenishment signal light 6: When the ship is replenishing supplies, the speed slows down to avoid the risk of collision, so they will light up to indicate other ships; they emit 360-degree red light, and in order to avoid mixing light with other lights of different colors, the installation distance must be greater than 2 meters.

[0029] Bow flagpole light 3: The light-emitting circular hole is 10mm and the light is directed toward the stern of the ship, giving the following ship a positioning center point so that it can follow and maintain the relative position.

[0030] Forward masthead light 4: A white light above the bow centerline showing an uninterrupted light within a 225-degree horizontal arc, used to observe other ships.

[0031] Lower track light 9: The horizontal luminous angle is 10 degrees. It can be used by other following ships to identify the course and position of the ship and keep the track of the entire ship group consistent.

[0032] The bottom of the bow and stern flagpoles of the present invention are equipped with a driving power box, which integrates the LED control device of each lamp to power the lamp. The driving power box is connected to the navigation light controller in the ship's cab, and each lamp can be switched at any time. Ensure reliable and stable navigation. At the same time, a wire hole is opened on the top or side of the flagpole for the lamp cable to pass through the hollow flagpole and connect to the internal wiring terminal of the driving power box, thereby hiding the cable and refining the design. All lamps are installed in a clamping style, which fits tightly with the flagpole and connects naturally.

[0033] The specific structure and installation method of the main lamp of the present invention are described in detail below.

[0034] 1. Bow anchor light structure Please continue to see Figure 5 The bow anchor light 1 of the present invention is mainly composed of an anchor light installation platform 12, a first upper cover 101, a first lampshade 102, a first light source module 103, a first shell 104, a first radiator 105, a bottom cover 106, a metal anti-bending cable connector 11, various sealing gaskets and various fasteners (such as: lampshade sealing gasket 107, bottom cover sealing gasket 108, screws).

[0035] The first upper cover 101, the first light source module 103, the first lampshade 102, the lampshade sealing gasket 107, and the first shell 104 are fixed to the upper and lower ends of the first radiator 105 by two M10 countersunk screws. The metal anti-bending cable connector 11 is screwed into the bottom cover 106. The bottom cover 106 has a groove, and the sealing gasket is placed in the groove. Then, the bottom cover 106 is fixed to the first shell 104 with 3 screws to achieve an IP66 waterproof structure. The whole lamp is fixed to the bow anchor lamp installation platform with 6 screws.

[0036] 2. First Supply Signal Light Currently, there is no supply signal light or navigation signal light installed on a flagpole on the market. Conventional navigation lights are large in size, and the platform bracket is welded on the metal bow and stern flagpoles and fixed to the platform by bolts. The welding cost and labor cost are very high, and spray protection is required after welding. All cables are exposed and the wiring is messy. The structural design does not take radar stealth into consideration and is easily detected by radar.

[0037] At present, all conventional supply signal lights with a 360° luminous angle use a transparent PC lampshade with a whole ring-shaped luminous surface, which increases the area that needs to be waterproofed and causes water leakage and water vapor ingress. In addition, the vertical light arc angle is large, which will illuminate the cab at night and affect the driver's night driving. In addition, the whole ring lamp needs to be installed in the middle of the flagpole when the flagpole is made, and it cannot be disassembled later.

[0038] Please continue to see Figure 6 The first replenishment signal lamp 2 of the present invention is completely different from the conventional one. It adopts a modular design and is divided into two independent modules. Each independent module is composed of a second upper cover 201, a second shell 204, a second light source assembly 203, a first upper cover sealing gasket 206, a second lampshade 202, a first lampshade pressure plate 207, and a fixing screw 16. The two independent modules are connected in the middle by a plug-in terminal, and then the two independent modules are locked to the middle of the flagpole 8 by the fixing screw 16, and a double waterproof structure is set between the two independent modules: a radial O-ring 15 and a flat washer 14, such as Figure 8 As shown, an anti-drop device is extended from one side of the housing, so that a horizontally arranged metal anti-bending cable connector 11 can be installed, and the lamp can be prevented from sliding down. The replenishment signal lamp takes up very little space and is difficult to be detected by radar.

[0039] The light-emitting surface of the supply signal light is 6 small square light outlets evenly distributed on each side, and each light outlet is sealed and waterproof by 1 light source board, 1 lampshade, 1 lampshade pressure plate and O-ring (that is, the second light source assembly 203 has 3 light source boards, and the number of the second lampshade 202 and the first lampshade pressure plate 207 are 3). The light-emitting angle can also reach 360°, and the vertical light arc angle of the light outlet is small, no other residual light is generated, and it will not shine into the cab.

[0040] 3. Bow Flagpole Light There are similar flagpole lamps at present, but they use a fixed hole method. The shell is riveted or screwed to the flagpole, which requires opening a large number of holes on the flagpole. 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.

[0041] See also Fig. 9 and Fig.10The bow flagpole lamp 3 of the present invention mainly includes a first front cover 301, a third lampshade 302, a third light source module 303, a third shell 304, a lens 305, a first front cover sealing gasket 306 and a second lampshade pressing plate 307; the flagpole conformal bow flagpole lamp adopts a metal ring 10 added to the flagpole to increase the strength of the carbon fiber flagpole, and is clamped to the metal ring 10 in a hoop-like manner, and an anti-slip device is extended from one side of the shell, so that the metal anti-bending cable connector 11 can be installed, and the lamp can be prevented from sliding down. A labyrinth waterproof structure is adopted between the first front cover 301 and the third shell 304.

[0042] 4. Forward Mast Light Currently, there is no mast light or navigation signal light with a clamp installed on a carbon fiber flagpole on the market. Conventional navigation lights are large in size, and are welded to the metal bow and stern flagpoles. The platform bracket is fixed to the platform by bolts, which has high welding and labor costs. After welding, spray coating is required for protection. All cables are exposed, the wiring is messy, and the structural design does not consider radar stealth, which makes it easy to be detected by radar. Moreover, all lamps and flagpoles are a beam structure. After being affected by waves and wind, the flagpole is subjected to great force, and there is stress concentration, which will cause safety hazards.

[0043] At present, the conventional front mast light has a luminous angle of 225°, and the luminous surface is a whole ring-shaped transparent lampshade plus an internal black shading plate to achieve the luminous angle, which increases the area that needs to be waterproofed and causes water leakage and water vapor. In addition, the vertical light arc angle is large, which will illuminate the cab at night and affect the driver's night driving.

[0044] The flagpole conformal front mast light is completely different from the conventional one. It uses a cylindrical lampshade and realizes the luminous angle by adding a shading plate. The problem is that the cylindrical lampshade will show the protruding area of ​​the arc surface from the ship's cab, and the dazzling afterglow will affect the driver's safe driving. The luminous surface of the front mast light 4 of the present invention is 3 small rectangular light outlets evenly distributed on each side. Each light outlet is sealed and waterproof by a light source board, a lampshade, a lampshade pressure plate and an O-ring. Fig.11 As shown, by changing the light source position and the size of the lampshade pressure plate, the light angle can reach 225°, and the vertical light arc angle of the light outlet is small, no other residual light is generated, and it will not shine on the deck to affect the judgment of the driver.

[0045] See also Fig.11 and Fig.12 The front mast lamp 4 of the present invention mainly includes a third upper cover 401 , a fourth lampshade 402 , a fourth light source module 403 , a fourth shell 404 , a fourth heat sink 405 , a second upper cover sealing gasket 406 and a third lampshade pressing plate 407 .

[0046] The flagpole conformal front mast light adopts a metal ring 10 added to the flagpole to increase the strength of the carbon fiber flagpole, and is clamped to the metal ring 10 in a hoop-like manner, and an anti-slip device is extended from one side of the shell, so that the metal anti-bending cable connector 11 can be installed, and the lamp can be prevented from sliding down. A labyrinth waterproof structure is adopted between the third upper cover 401 and the fourth shell 404. The front mast light is perfectly integrated with the flagpole and occupies very little space, making it difficult to be monitored by radar.

[0047] 5. Stern Anchor Light The structure of the stern anchor light 5 is consistent with the bow anchor light 1 mentioned above. The anchor light installation platform 12 is in line with the inclination angle of the stern flagpole, and a horizontal installation platform is made and fixed to ensure that the light emitting angle of the lamp is horizontal 0 degrees. The installation method of the stern anchor light 5 is the same as that of the bow anchor light 1. I will not go into details here, please refer to the above for details.

[0048] 6. Second Supply Signal Light Conventional lamps on the stern flagpole with a 15-degree inclination are made of metal materials, and then a platform is welded in the middle of the flagpole. First, it is difficult to process, second, it is difficult to ensure the level of the platform after welding, and third, it is difficult to lay flat when the flagpole is laid down, which can easily damage the lamps and make maintenance very difficult. Moreover, all lamps and flagpoles are a beam structure. After being affected by waves and wind, the flagpole is subjected to great force, and there is stress concentration, which will cause safety hazards.

[0049] Currently, there is no such lamp installed on the 15-degree inclined stern flagpole on the market. After the supply signal light meets the inclined clamp installation, the horizontal luminous angle can still meet the requirements of the GB3028-2012 "Marine Electrical Lights" standard. And it takes up little space and is not easily detected by radar.

[0050] The existing problems and solutions of the second supply signal light 6 on the stern flagpole are consistent with those of the first supply signal light 2 on the bow flagpole, and mainly include a fourth upper cover 601, a fifth lampshade 602, a fifth light source module 603, a fifth shell 604, a fifth radiator 605, a third upper cover sealing gasket 606, and a fourth lampshade pressing plate 607. Fig.14 and 15 As shown; the specific structure is not described here, see above for details.

[0051] 7. Stern light (tow light) Conventional lamps on the stern flagpole with a 15-degree inclination are made of metal materials, and then a platform is welded in the middle of the flagpole. First, it is difficult to process, second, it is difficult to ensure the level of the platform after welding, and third, it is difficult to lay flat when the flagpole is laid down, which can easily damage the lamps and make maintenance very difficult. Moreover, all lamps and flagpoles are a beam structure. After being affected by waves and wind, the flagpole is subjected to great force, and there is stress concentration, which will cause safety hazards.

[0052] There are similar flagpole lamps on the market, but they use a fixed hole method. The shell is riveted or screwed to the flagpole, which requires opening a large number of holes on the flagpole. 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.

[0053] See also Fig.16 and Fig.17 The stern light 7 of the present invention mainly includes a second front cover 701, a sixth lampshade 702, a sixth light source module 703, a sixth housing 704, a sixth heat sink 705, a second front cover sealing gasket 706, a fifth lampshade pressing plate 707, a wire clamp 708 and a busbar 709; The stern light (towed light) adopts a metal ring 10 added to the flagpole to increase the strength of the carbon fiber flagpole, and is clamped to the metal ring 10 in a hoop-like manner, and an anti-slip device is extended from one side of the shell to install the metal anti-bending cable connector 11 and prevent the lamp from sliding down. A labyrinth waterproof structure is adopted between the second front cover 701 and the sixth shell 704.

[0054] 8. Lower track lights Conventional lamps on the stern flagpole with a 15-degree inclination are made of metal materials, and then a platform is welded in the middle of the flagpole. First, it is difficult to process, second, it is difficult to ensure the level of the platform after welding, and third, it is difficult to lay flat when the flagpole is laid down, which can easily damage the lamps and make maintenance very difficult. Moreover, all lamps and flagpoles are a beam structure. After being affected by waves and wind, the flagpole is subjected to great force, and there is stress concentration, which will cause safety hazards.

[0055] There are similar flagpole lamps on the market, but they use a fixed hole method. The shell is riveted or screwed to the flagpole, which requires opening a large number of holes on the flagpole. 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.

[0056] See also Fig.18 and Fig.19 The lower track light 9 of the present invention mainly includes a third front cover 901, a seventh lampshade 902, a seventh light source module 903, a seventh shell 904, a seventh radiator 905, a third front cover sealing gasket 906, a sixth lampshade pressing plate 907, a rotary switch 908, a mounting plate 909 and a sealing ring 910.

[0057] At present, conventional lower track lights use a mechanical grille structure to block the light source to achieve switching of different light intensities. This lower track light 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 switch 908, the switching of different light intensities can be achieved by rotating different gears.

[0058] The lower track light adopts a metal ring 10 added to the flagpole to increase the strength of the carbon fiber flagpole, and is clamped to the metal ring 10 in a hoop-like manner, and an anti-slip device is extended from one side of the shell to install a metal anti-bending cable connector 11, which can also prevent the lamp from sliding down. A labyrinth waterproof structure is adopted between the third front cover 901 and the seventh shell 904.

[0059] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
