Figure 1 , that is, the light source 11 is located inside the outdoor lamp body, the light source 11 is connected to the power source 5, and the power source 5 is connected to the cable 6. This structure has the following problems: (1) The heat-generating light source 11 is installed inside the outdoor lamp body. The thermal effect will cause the insulation material to age faster and the sealing performance to deteriorate, which will cause water vapor to enter the lamp in the outdoor environment, causing corrosion damage and affecting the insulation performance of the power system. At the same time, due to the poor accessibility of the installation location, it is difficult to repair and replace. (2) The light source 11 is inside the lamp, which limits the external structure of the outdoor lamp. It is costly and difficult to optimize the external structure such as RCS stealth. (3) The light source 11 is inside the lamp and generates heat radiation to the outside, so it is costly and difficult to carry out infrared stealth. (4) There are many antennas in open-air areas, and the light source 11 of the lamp is equipped with a power module, which requires special electromagnetic compatibility design, resulting in an increase in the cost of the lamp.

[0003] Therefore, it is necessary to provide a new outdoor lamp to solve the above problems. Summary of the invention

[0021] The invention provides an outdoor lamp for a ship.

[0022] The present invention provides a first embodiment of an outdoor lighting device for a ship. Figure 2In this embodiment, an outdoor lamp for a ship includes a remote light emitter 1 located in the ship cabin, an outdoor lamp body 4 located outside the ship cabin, and a lighting optical fiber cable 2 connecting the remote light emitter 1 and the outdoor lamp body 4 (the lighting optical fiber cable 2 in the prior art is used, and the lighting optical fiber cable 2 can realize the transmission of light from the remote light emitter 1 to the outdoor lamp body 4 with almost no loss), wherein, The remote light emitter 1 comprises a light source 11, a filter 12 covered outside the light source 11, and a light mixing component located on the light output side of the filter 12, the light mixing component is used to collect the light filtered by the filter 12 into the light mixing component, and the light mixing component is connected to the lighting optical fiber cable 2 through a light source connector 3 (the light source connector 3 in the prior art is used, the same below); The outdoor lamp body 4 includes a lamp holder 41 and a reflector 42 mounted on the lamp holder 41. The lamp holder 41 is connected to the lighting optical fiber cable 2 through the light source connector 3. The reflector 42 is used to reflect and diverge the light reflected by the lighting optical fiber cable 2. The outer cover of the remote light emitter 1 is provided with a sealing cover to improve its service life and sealing performance and prevent impurities from affecting the accuracy of its internal parts.

[0023] Specifically, this embodiment proposes a specific structure of a light mixing component: the light mixing component includes a light emitting device 13, a heat reflector 14 and a light mixer 15 which are sequentially arranged on the light emitting side of the filter 12, the light emitting device 13 is used to emit the light filtered by the filter 12 in parallel, the heat reflector 14 is used to converge the parallel light emitted by the convex lens into a beam and enter the light mixer 15, and the light mixer 15 is used to transmit the gathered light in parallel. The light source 11 can be a halogen lamp or a laser or other light sources, which is not limited in this embodiment.

[0024] In this embodiment, the light emitting device 13 and the heat reflector 14 are both convex lenses. The filter 12 is an absorption filter, which is made of glass (inorganic or organic compounds are added to the glass), and is used to filter light in the infrared wavelength range.

[0025] Furthermore, in this embodiment, the outdoor lamp body 4 further includes a concave lens 43 for diverging the light in the light source connector 3 . The concave lens 43 is mounted on the lamp holder 41 and is located at the outlet side of the light source connector 3 .

[0026] This embodiment proposes a specific structure of a lamp holder 41: the lamp holder 41 includes a top plate and a bottom plate that are arranged opposite to each other, and a side plate connecting the top plate and the bottom plate. The side plate is a transparent plate, and the transparent plate is coated with a color correction coating 44 for filtering the color of light reflected by the heat reflector 14.

[0027] The lamp holder 41 is sealed and hollow inside, and its inner chamber is filled with nitrogen. The reflector 42 is detachably mounted on the top plate. The reflector 42 can be made of highly reflective materials such as aluminum-plated glass.

[0028] In this embodiment, the reflector 42 is a conical structure, and the center line of the conical surface is aligned with the center line of the concave lens 43 to improve the utilization rate of the light from the light source 11. The bottom surface of the conical structure is mounted on the top plate of the lamp holder 41.

[0029] The working principle of the outdoor lamp for ships is as follows: the light source 11 first enters the filter 12, and the filter 12 filters out the light in the infrared wavelength range. The light from the filter 12 passes through the light emitting device 13, which is a convex lens, and emits the light emitted by the light source 11 in parallel. The heat reflector 14 converges the parallel light emitted by the light source 11 into a beam and enters the light mixer 15, and the light mixer 15 transmits the gathered light in parallel. The light is transmitted to the outdoor lamp body 4 outside the ship's cabin through the lighting optical fiber cable 2, and the concave lens 43 on the light-incoming surface of the lamp holder 41 diverges the light in the light source connector 3. The conical reflector emits the diverged light from the transparent side panel of the lamp holder 41. The color correction coating 44 is on the outermost side of the transparent side panel of the lamp holder 41. It is a lens of a certain color that can emit light of a specific color.

[0030] The outdoor lighting device for ships provided by the present invention has the following beneficial effects: 1. The lamp is divided into two parts: a remote light emitter 1 and an open-air lamp body 4. The light source 11 is installed on the remote light emitter 1 in the cabin instead of being installed outside the cabin in the prior art. Therefore, there is no problem that water vapor outside the cabin enters the light source 11 and affects the operation of the light source 11, thereby increasing the service life of the light source 11. 2. The lamp is divided into two parts, the remote light emitter 1 and the open-air lamp body 4, instead of using a complex structure to improve the sealing of the lamp. This structure has the advantage of low cost; 3. The light source is located inside the cabin, and its installation position has good accessibility, so it is easy to repair the light source 11, which solves the problem of difficulty in timely maintenance caused by poor accessibility of the light source 11 outside the cabin in the prior art; 4. Since the light source 11 is located inside the cabin, the external open-air lamp body 4 is not restricted by the light source 11 and can be set in various shapes and can be conformed to the outer shell of the hull, thereby improving the stealth of the lamp and solving the problem of high cost and difficulty in optimizing the appearance of existing lamps such as RCS stealth; 5. The light source 11 is inside the cabin and does not generate heat radiation to the outside, thus further improving the stealth of the lamp; 6. The light source 11 is inside the cabin and will not interfere with the numerous antennas outside the cabin. Therefore, compared with the prior art, no separate electromagnetic compatibility design is required, thereby reducing the manufacturing cost of the lamp.

[0031] The present invention proposes a second embodiment of an outdoor lamp for a ship. This embodiment is different from the first embodiment described above in that the reflection angle of the reflection surface of the reflection device 42 is adjustable. The reflection device 42 is made of a flexible material, so that it is easy to adjust the angle between the conical surface and the bottom surface of the conical structure, thereby achieving the need to adjust the intensity of the reflected light, and thus achieving the purpose of adjusting the brightness of the light emitted by the lamp.

[0032] The invention also provides a ship.

[0033] In this preferred embodiment, a ship includes the above-mentioned outdoor lighting for ships. The specific structure and beneficial effects of the outdoor lighting for ships refer to the above-mentioned embodiment and will not be described in detail here.

[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
