Description

Navigation lights for ships and control boards therefor {NAVIGATION LIGHT FOR VESSEL AND CONTROL BOARD FOR THE SAME}

The present invention relates to a navigation light, and more particularly, to a navigation light for a vessel and a control board for the same, which can reliably operate and function even in a cryogenic environment or a humid environment through an excellent self-heating function.

A navigation light is a device to secure a safe navigation environment by preventing mutual collisions on ships, and refers to 1 or 2 light type traffic lights such as long lights, port lights, star lights, stern lights, and towing lights. . A navigation light is a lighting device that refracts and reflects light from a light source using a lens or reflector, collects the light and emits it to the outside. These navigation lights are installed at a specific location on the ship in accordance with the International Maritime Collision Prevention Regulations, etc.

Navigation lights are mainly used at night, and are also used when visibility is limited by fog or smoke. The navigator expresses his/her intentions about the operation of the vessel by turning on or flashing the navigation lights so that the navigators of other vessels can recognize the position and direction of the vessel in operation, and the will to operate such as overtaking. In particular, ships operating in extremely low-temperature polar regions such as the North or South Pole must be installed and operated so that the light of navigation lights can be seen normally from the outside even in natural phenomena such as snow, ice, and frost.

However, when seawater, snow, ice, frost, etc. stick to the surface of the navigation light in the extremely low-temperature polar region, it often occurs that the navigation light cannot be used properly as a lighting device for expressing opinions about vessel operation. In such a case, it is difficult for the navigator, master, or crew to remove ice or frost directly from the surface of the sailing light supported by a mast, pole, or the like. As such, there is a demand for a navigation light having a new configuration that can block factors that interfere with the normal operation of the navigation light even in extremely low-temperature polar regions.

On the other hand, a transparent conductive film is a kind of film on which a conductive material is deposited, and can change the resistance, durability, and electrical properties of the film surface, and is widely used in industry because it is transparent and conducts electricity. It is also used as a transparent heater material, and its range of applications is increasing. Particularly widely used is Indium Tin Oxide (ITO), which is generally deposited by a high-temperature deposition technique and has been used for a long time as a transparent electrode. Transparent heater films using oxides mixed with various metals (Zinc, Aluminum, Gallium, etc.), CNTs, and Ag nanowires are also being developed.

In general, ITO material is used for electronic products, but indium is a scarce metal and the price increases over time, which causes difficulties in economic terms, and limits in that it is almost impossible to use as a flexible material. have. In addition, since most depositions are possible at high temperatures, large-area process costs are high.

When used as a heating element, it can be broadly divided into a linear heating element and a planar heating element when divided by the external shape. A linear heating element is a linear heating element often called a heating wire, and is used to remove snow or frost by arranging a heating wire on the side glass and rear glass of a vehicle in particular. It is made by bonding nichrome wire and copper wire to glass in a thread-like form. Since the heat starts from the part around the heating wire, the heat distribution between the heating wires is low, so the heat dissipation of the entire surface is not even, and when used as a sight glass, visibility is not secured because it is not transparent. In addition, if any one part of the heating wire is cut off, there is a problem that electricity does not pass.

On the other hand, a planar heating element uses a thin metal plate or uses a heating paint or carbon fiber, and heat is generated over the entire surface by installing electrodes at both ends of the heating element. When using carbon fibers, a CNT film as a planar fuming body can be prepared by spraying a carbon nanotube (CNT) liquid on a transparent substrate and firing it.

On the other hand, the conventional planar heating element has the advantage of generating heat from the entire surface, but is difficult to use for sight glasses due to poor light transmittance. In addition, general PET (Polyethylene Terephthalate) or the like is used as a substrate, so it is easy to scratch and has poor durability. As a planar heating element, it is transparent, so it can be used for various purposes, and it is necessary to improve the technology that has excellent durability and can generate heat even with low power.

1 and 2, the navigation light 100 according to the present embodiment is a bottom frame 10, a top frame 20, a navigation light glove 30, and a heating device. (50) is provided. In this embodiment the heating device 50 is disposed on the inner surface of the navigation light glove 30 . The bottom frame 10 and the top frame 20 may be referred to as a navigation light frame, and a navigation light globe 30 may be disposed between them.

In addition, the navigation light 100 may include a light source unit 40 surrounded by the navigation light globe 30 in the navigation light frame. The light source unit 40 may include a halogen lamp, a light emitting diode (LED) lamp, a metal lamp, a mercury lamp, and the like. In that case, the light source unit 40 may include a dedicated driving driver or a dedicated ballast circuit depending on the type of lamp.

In addition, the navigation light 100 may be equipped with a control board 70 for automatically controlling the thermal environment according to the ambient temperature. An example of the control board 70 will be described later with reference to FIG. 7 .

FIG. 4 is a partial front view for explaining an aspect in which the heating device of FIG. 3 is applied to a navigation light. FIG. 5 is a partially enlarged front view of the heat generating device of FIG. 4 . And FIG. 6 is a graph for explaining the operation result of the heat generating device of FIG.

Referring to FIG. 3 , the heating device 50 that can be employed for navigation lights according to the present embodiment includes a base substrate 51 , a heating film 52 , an electrode part 53 , and a protective film 54 . . The heating film 52 is laminated on one surface of the base substrate 51 , the electrode part 53 is laminated on a part of one surface of the heating film 52 , and the protective film 54 is a part of the electrode part 53 . is placed and laminated on the heating film 52 .

The base substrate 51 and the protective film 54 may be a heat-adhesive film in which an adhesive function is activated by heat or a photo-adhesive film in which an adhesive function is activated by light, and when considering convenience, reliability, cost, etc. It is preferable that it is a photo-adhesive film using a photocurable resin. In addition, the base substrate 51 may be a transparent film or a double-sided adhesive film, and the protective film 54 may have an insulating function or may be an insulating film and/or a one-sided adhesive film.

The heating film 52 includes a base substrate 521, a metal oxide layer 523 formed on the base substrate 521, and a spherical dot-shaped thermal material formed on the metal oxide layer 523 and arranged in a grid. 525 , and a conductive adhesive layer 527 formed on the metal oxide layer 523 and the thermal material 525 may be provided.

The thermal material 525 is tin fluoride (SnF ₂ ), tin tetrafluoride (SnF ₄ ), tin nickel fluoride (SnNiF), tin chromium fluoride (SnCrF), tin zinc fluoride (SnZnF), zinc nickel fluoride (ZnNiF), or these and a material selected from the group consisting of combinations of

In this embodiment, the heating film 52 may be installed in the form of a stripe or a stripe on the inner surface of the navigation light glove, as shown in an enlarged view of a portion 52a of FIG. Each stripe-shaped line functions as a heating wire, and for this, the metal oxide layer and the thermal material may have a form in which a predetermined number of thermal element points are arranged in the width direction. In this case, it is possible to greatly reduce the blocking or scattering of light from the light source by the metal oxide layer or the thermal material.

The diameter d1 of the thermal source points disposed on each heating wire is 50 nm to 100 nm, as shown in FIG. 5 , when a portion 52b of the heating film is enlarged, and the spacing w1 between adjacent thermal source points is 10 nm to 20 nm.

The thermal material is a material manufactured by ECR (electron cyclotron resonance) MOCVD (metal organic chemical vapor deposition) method, and a heating device can be manufactured by coating and transferring a nano dot material on a substrate (base substrate). And, the manufactured heating device can generate heat by applying a current to quickly increase the temperature of the corresponding part of the navigation light to the target temperature.

Referring back to FIG. 3 , the heating device 50 may be formed by attaching the electrode part 53 to the metal composite oxide film 52 in which the metal oxide layer is formed on the base substrate by lining. In this case, the thermal material base substrate of the thermal material film layer may be removed from the conductive adhesive layer of the film through a roller winder process.

The electrode part 53 may be stacked on an area of a predetermined size or more of the heating film 52 for power supply or voltage/current application. In this case, the shape of the overlapping region of the heating film 52 and the electrode part 53 may have a shape extending along a part of the outer line according to the planar shape of the heating film 52 .

The metal oxide layer 523 of the heating film 52 may be formed by depositing a metal oxide on the base substrate 521 . Deposition is carried out at room temperature, and a chemical vapor deposition method may be used, but is not limited thereto. In the chemical vapor deposition method, for example, a voltage may be applied to a metal oxide precursor to form overcondensed metal ions, and the formed metal ions may be deposited on the surface of the base substrate through chemical bonding. If the chemical vapor deposition method is used at room temperature, a polymer that is weak to heat can be deposited on the base substrate, and there is an advantage in that it is easy to deposit a large area.

The thermal material 525 may be formed in a spherical shape on an adhesive film in which a conductive adhesive is formed on the base substrate 521 . In that case, the conductive material or the material of the metal oxide layer 523 may include a metal material such as nickel (Ni), silver (Ag), or Ni/Au, and the adhesive or adhesive layer 527 may be a photocurable type. have.

Here, a portion of the spherical thermal material 525 may be covered by the metal oxide layer 523 and the remaining portion of the thermal material 525 may be covered by the conductive adhesive layer 527 . In addition, a portion covering the thermal material 525 in the metal oxide layer 523 of the heating film 52 may function as a diffusion layer or a thermal diffusion layer.

The above-described sphere-shaped thermal material 525 may be formed by a room temperature chemical continuous process. In the room temperature chemical continuous process, the microwave generated by the microwave generator is guided to a magnetic field forming space, a plasma source gas is supplied into the magnetic field forming space, and the plasma source gas is exposed to microwaves in the magnetic field forming space to maintain a plasma state, Electro cyclotron resonance (ECR) of electrons and ions in the plasma under the influence of a magnetic field to maintain high energy density plasma, and activate ions by injecting a thermal material source gas for forming a deposition film into the high energy density plasma region and the activated ions may include a series of steps to form (deposit) a spherical thermal material through an instantaneous surface chemical reaction on the surface of the adhesive layer.

In addition, the process of forming the thermal material 525 described above may be performed to form the thermal material points in a lattice arrangement and uniform distribution compared to the sputtering method for forming the dispersed nano dots. The thermal material 525 arranged in a lattice form has an appropriate diameter of 50 nm to 100 nm, and when it is out of this range, the thermal acceleration characteristic may be deteriorated as structural stability is reduced. In addition, if the distance between adjacent thermal materials arranged in a grid is less than 10 nm, the optical properties tend to be deteriorated, and if it is larger than 20 nm, the optical properties are good, but the thermal storage properties are poor, so that the thermal acceleration performance may be reduced.

According to the configuration of the heating film 52 described above, the heat storage regions formed around the adjacent thermal materials interact to form a hyperaccelerated thermal region exhibiting a synergistic effect. When a thermal material is used, as shown in FIG. 6, the hyperacceleration temperature is 30°C higher than the temperature in the case of no thermal material from room temperature to about 97°C for 60 seconds after power is turned on, about 67°C (when 60 seconds have elapsed) It can be seen that the temperature rises from room temperature to about 115°C for 300 seconds and is maintained at about 17°C higher than the temperature of 98°C when there is no thermal material.

The power supply unit 72 may supply power to the heat generating device or stop supplying power according to a signal from the switching unit 71 .

The sensor 73 includes a temperature sensor that detects a temperature outside or inside the navigation light frame. The sensor 73 may be electrically connected to the control module 74 to transmit the measured signal to the control module 74 .

The control module 74 may periodically or intermittently activate the switching unit 71 according to a preset time or period according to the temperature measured by the sensor 73 . The control module 74 may include an input unit 75 , a comparison unit 76 , and a driving output unit 77 .

The input unit 75 of the control module 74 converts the signal of the sensor 73 into a signal shape or size that can be processed by the comparator 76 . The input unit 75 may include an analog-to-digital converter or an amplifier. The comparator 76 compares the signal of the sensor 73 with a plurality of reference levels or a reference table signal to determine the ambient temperature level of the navigation light. When the output of the comparator 76 is a preset signal or a preset signal level, the driving output unit 77 may apply a preset voltage or current to the switching unit 71 to activate the switching unit 71 . According to the signal of the driving output unit 77, the switching unit 71 is turned on or turned off, whereby the power supply unit 72 can supply power to the electrode unit of the heating device.

According to this embodiment, it is possible to manually and automatically control the thermal environment of the navigation light through the control board 70, it is possible to maximize user convenience.

11 to 13 are perspective views for explaining a navigation light according to another embodiment of the present invention.

In these embodiments, various designs of sailing lights for ships to which a transparent heating film is applied are exemplified.

Referring to FIG. 11 , the navigation lamp 100 according to the present embodiment is a lighting device having a heat material-based heat generating device and may be used after being modified in various shapes and structures. For example, even when the navigation light globe 30 has a curved surface, the thermal environment of the navigation light can be effectively improved by attaching the heating device 50 on the concave inner surface of the navigation light globe 30 .

In addition, as shown in FIG. 12 , the navigation light 100 according to the present embodiment may be implemented in the form of a navigation light having two light-type globes 30a and 30b. The second-class globes 30a and 30b may have a structure in which an outer surface in the form of a concave valley is disposed between two convex outer surface portions.

As shown in the thermal test results, the average temperature rises to zero (0°C or higher) within 30 minutes even in a cryogenic environment and at low power, indicating that sufficient heat generation is possible for the operation of the appliance.

[Table 1] shows the temperature of each part of the navigation light when 30 minutes have elapsed after operating the navigation light at an external temperature of -30℃.

at -30℃ external T external TC external C external BC outside B outside (chamber) temperature [℃]
