Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a multifunctional luminaire and a zone control method. Background Technology

[0002] Aircraft landing lights, turn signals, and taxi lights are critical lighting devices that ensure aircraft safety during takeoff, landing, and taxiing. Landing lights are installed at the wing roots, under the fuselage, or on the nose landing gear, illuminating the runway during takeoff and landing. Turn signals are installed on the nose landing gear strut or wing roots, one on each side, pointing to the sides, illuminating the lateral areas after landing when the aircraft is rapidly leaving the runway or turning during taxiing, thus assisting in steering. Taxi lights are installed on the nose landing gear strut to illuminate the taxiway ahead, guiding the aircraft safely during taxiing.

[0003] Currently, landing lights, turn signals, and taxi lights on the market are all single-function designs, installed independently to meet the needs of their respective scenarios. Therefore, multiple installation locations need to be set up on the aircraft to meet the installation requirements of landing lights, turn signals, and taxi lights respectively. This is complex to install, occupies fuselage space, and imposes additional restrictions on fuselage structural design. At the same time, the installation of multiple lights will lead to higher costs for lighting materials, mold development, and labor installation, resulting in significant overall cost pressure. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multifunctional lighting fixture and a zone control method, which can greatly reduce the cost of lighting fixture materials, molds and labor, and simplify installation.

[0005] To address the aforementioned technical problems, this invention provides a multifunctional lamp, comprising a ring module, several light source modules, a heat dissipation module, and a zone controller. The ring module is positioned above the light source modules, which are housed within the heat dissipation module. Each light source module includes a circuit board and several arrayed light source units packaged on the circuit board. Each light source unit includes a lens bracket, a lens unit, and a light source, which are sequentially arranged from top to bottom within the lens bracket. The ring module has light emission holes corresponding to each light source unit, positioned above the corresponding light source unit. Light emitted by the light source passes sequentially through the lens unit and the corresponding light emission hole. The zone controller is connected to the circuit board to control the operating state of the light source.

[0006] As an improvement to the above solution, the surface ring module includes several surface ring units, the heat dissipation module includes several heat dissipation units, and the heat dissipation unit includes a receiving cavity and a heat sink disposed at the bottom of the receiving cavity; the surface ring units, heat dissipation units and light source modules correspond one-to-one, the light source module is disposed in the receiving cavity of the corresponding heat dissipation unit, and the surface ring unit is disposed above the corresponding light source module.

[0007] As an improvement to the above solution, the heat dissipation module includes at least two heat dissipation units arranged in a stepped manner.

[0008] As an improvement to the above solution, the lens support includes a first support and a second support, which are joined together to form a tubular structure.

[0009] As an improvement to the above solution, the inner wall of the lens holder is provided with a number of annular grooves from top to bottom, and the annular grooves are used to fix the lens of the lens unit.

[0010] As an improvement to the above solution, the outer wall of the lens bracket is provided with a fixing member, and the lens bracket is connected to the face ring module through the fixing member.

[0011] As an improvement to the above solution, the partition controller includes a main controller, a backup controller, a first conversion module, a second conversion module, and a third conversion module. The input terminal of the first conversion module is connected to an external power supply, and the output terminals are respectively connected to the light source modules, used to boost the external power supply to power the light source modules respectively. The input terminal of the second conversion module is connected to an external power supply, and the output terminal is connected to the main controller, used to step down the external power supply to power the main controller. The input terminal of the third conversion module is connected to an external power supply, and the output terminal is connected to the backup controller, used to step down the external power supply to power the backup controller. The main controller is connected to the light source modules to control the working state of the light source modules. The backup controller is connected to the light source modules to control the working state of the light source modules.

[0012] As an improvement to the above scheme, the light source units are distributed in a rectangular grid array.

[0013] As an improvement to the above solution, the multi-functional lamp also includes a mounting bracket connected to the face ring module, the mounting bracket being used to fix the multi-functional lamp to an external device.

[0014] Accordingly, the present invention also provides a zone control method based on a multifunctional lighting fixture, comprising: the zone controller acquiring aircraft data and environmental data in real time, wherein the aircraft data includes altitude information, pitch angle information, turning angle information, and roll angle information, and the environmental data includes weather information; the zone controller generating control signals based on the aircraft data and environmental data, wherein the control signals include switching signals, emission angle signals, and brightness signals; and the zone controller sending the control signals to the light source module respectively to control the working state of each light source in the light source module.

[0015] Implementing this invention has the following beneficial effects: This invention provides a multi-functional light fixture that can be installed on aircraft. Only one installation location is required to replace the original three separate installation locations for "landing light, turning light, and taxiing light," greatly reducing the cost of lighting materials, molds, and labor, simplifying installation, and enabling a single light to achieve "three-in-one" functionality.

[0016] More preferably, the components of the multifunctional lamp of the present invention adopt a unique connection method, which can not only achieve a stable connection between the components, but also adapt to the actual use needs of the aircraft, making it highly practical and flexible.

[0017] Furthermore, the multifunctional lamp of the present invention forms a redundant power supply network through three independent conversion modules (i.e., the first conversion module, the second conversion module, and the third conversion module), which can take into account both automatic control and emergency manual control, effectively avoid the overall system failure caused by a single power supply failure, and meet the high redundancy requirements of aviation equipment; at the same time, each light source module is independently powered by the first conversion module, which can effectively support redundant switching in the event of a single module failure and improve the overall availability of the system.

[0018] In addition, the zonal control method of the present invention based on multi-functional lighting fixtures can intelligently judge the scene according to aircraft data and environmental data, and control the working status of the light source in different areas of the multi-functional lighting fixtures respectively, so as to realize the functions of landing lights, turning lights and taxiing lights; at the same time, it can also effectively ensure that the light source emitted by the multi-functional lighting fixtures always automatically keeps aligned with the runway, so as to achieve targeted lighting.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0021] See Figure 1 and Figure 2 , Figure 1 and Figure 2 The first embodiment of the multifunctional lamp of the present invention is shown, which includes a surface ring module 1, a plurality of light source modules 2, a heat dissipation module 3, and a zone controller 4, specifically: The surface ring module 1 is located above the light source module 2, and the light source module 2 is located inside the heat dissipation module 3; therefore, the surface ring module 1 and the heat dissipation module 3 can effectively encapsulate the light source module 2, resulting in strong safety and stability. The light source module 2 includes a circuit board 21 and several light source units 22 arranged in an array on the circuit board 21 (see...). Figure 3 The light source unit 22 includes a lens bracket 221, a lens unit 222 and a light source 223, which are arranged sequentially from top to bottom inside the lens bracket 221. The surface ring module 1 has light-emitting holes 11 that correspond one-to-one with the light source unit 22. The light-emitting holes 11 are located above the corresponding light source unit 22. The light emitted by the light source 223 passes through the lens unit 222 and the corresponding light-emitting holes 11 in sequence and is emitted outward, thereby ensuring that the light is accurately adapted to the scene requirements after being optimized by the lens unit 222. The zone controller 4 is connected to the circuit board 21 to control the working status of the light source 223.

[0022] It should be noted that the number of light source modules 2 and light source units 22 can be set according to the actual situation; in this embodiment, three light source modules 2 can be set, and each light source module 2 is equipped with four light sources 223. Preferably, the light source units 22 are distributed in a rectangular grid array to facilitate the zoned control of the light sources 223.

[0023] The multifunctional lamp of the present invention can be installed on an aircraft and receive data and issue commands through the zone controller 4 to control the working state of the light source 223 (e.g., on / off state, light emission angle state, and brightness state), thereby realizing zone control of different light sources 223, automatically keeping the illumination aligned with the runway, so as to realize the basic functions of three types of lights: landing lights, turning lights, and taxi lights, improve the pilot's perception of the external environment, and reduce the operational burden.

[0024] Therefore, the multifunctional lamp of the present invention only needs to reserve one installation position on the aircraft to replace the original three independent installation positions of "landing light, turning light and taxi light", which greatly reduces the cost of lamp materials, molds and labor, simplifies installation, and realizes the "three-in-one" function with a single lamp.

[0025] like Figure 2 As shown, the face ring module 1 includes several face ring units 12, and the face ring units 12 are interconnected by a connecting plate 13. The heat dissipation module 3 includes several heat dissipation units 31. Each heat dissipation unit 31 includes a receiving cavity 311 and a heat sink 312 disposed at the bottom of the receiving cavity 311. In this embodiment, the heat sink 312 is a finned heat sink. Furthermore, in order to meet the high power heat dissipation requirements when the landing light, turn signal and taxiing light are turned on simultaneously, other heat pipe heat dissipation solutions can be added to the receiving cavity 311, which is not limited here.

[0026] The surface ring unit 12, the heat dissipation unit 31 and the light source module 2 are in one-to-one correspondence. The light source module 2 is located in the receiving cavity 311 of the corresponding heat dissipation unit 31, and the surface ring unit 12 is located above the corresponding light source module 2.

[0027] Therefore, the surface ring module 1 and the heat dissipation module 3 can effectively encapsulate the light source module 2 and efficiently dissipate heat from the light source module 2 to ensure that the operating temperature of the light source module 2 is maintained between 25.26℃ and 100.00℃.

[0028] Furthermore, to adapt to the actual usage requirements of the aircraft, the heat dissipation unit 31 of the heat dissipation module 3 is designed in a stepped layout. In practical applications, heat dissipation units 31 with different data can be set according to requirements, as long as the heat dissipation units 31 are arranged in a stepped manner. In this embodiment, the heat dissipation module 3 includes three heat dissipation units 31 arranged in a stepped manner.

[0029] Similarly, to match the stepped layout of the heat dissipation unit 31, the surface ring module 1 is designed with a stepped structure that matches the heat dissipation unit 31.

[0030] like Figure 3As shown, the lens bracket 221 includes a first bracket 2211 and a second bracket 2212. The first bracket 2211 and the second bracket 2212 are assembled together to form a tubular structure, which facilitates disassembly and installation.

[0031] Furthermore, the outer wall of the lens bracket 221 is provided with a fastener 2213, and the lens bracket 221 is connected to the face ring module 1 through the fastener 2213.

[0032] like Figure 4 As shown, the inner wall of the lens holder 221 is provided with several annular grooves from top to bottom. The annular grooves are used to fix the lens 2221 of the lens unit 222.

[0033] It should be noted that multiple lenses 2221 can be set in the lens unit 222. In practical applications, the number of lenses 2221 and the parameters of each lens 2221 can be flexibly set according to the requirements. In this embodiment, three lenses 2221 can be set in the lens unit 222.

[0034] like Figure 5 As shown, the partition controller 4 includes a main controller 41, a backup controller 42, a first conversion module 43, a second conversion module 44, and a third conversion module 45, specifically: The input terminal of the first conversion module 43 is connected to an external power supply, and the output terminal is connected to the light source module 2 respectively. It is used to boost the external power supply to supply power to the light source module 2 respectively. The input terminal of the second conversion module 44 is connected to an external power supply, and the output terminal is connected to the main controller 41. It is used to step down the external power supply to supply power to the main controller 41. The input terminal of the third conversion module 45 is connected to an external power supply, and the output terminal is connected to the backup controller 42. It is used to step down the external power supply to supply power to the backup controller 42. The main controller 41 is connected to the light source module 2 to control the working state of the light source module 2; The backup controller 42 is connected to the light source module 2 to control the working state of the light source module 2; in practical applications, the backup controller 42 can be a backup control device such as a manual controller.

[0035] It should be noted that the main power supply of the partition controller 4 comes from the aircraft's 28V power supply system (i.e., external power supply), and a redundant power supply network can be formed through three independent DC-DC conversion modules (i.e., the first conversion module 43, the second conversion module 44, and the third conversion module 45). Among them, the first conversion module 43 is the core power supply link, which can convert the external power supply from 28V to 48V to provide working power for each light source module 2; the second conversion module 44 is the main power supply link, which can convert the external power supply from 28V to 5V to power the main controller 41; and the third conversion module 45 is the backup power supply link, which can convert the external power supply from 28V to 5V to power the backup controller 42.

[0036] Therefore, the multi-functional lamp of the present invention adopts a dual control channel design with main and backup, which takes into account both automatic control and emergency manual control. It can effectively avoid the overall system failure caused by a single power supply failure and meet the high redundancy requirements of aviation equipment. At the same time, each light source module 2 in the multi-functional lamp of the present invention is independently powered by the first conversion module 43, which can effectively support redundancy switching when a single module fails and improve the overall availability of the system.

[0037] Furthermore, in the multifunctional lamp of the present invention, the main controller 41 interacts with the flight control system through communication signals. The main controller 41 sends control commands (such as switch signals, light emission angle signals, brightness signals and synchronization signals) to each light source module 2 according to the aircraft data and environmental data collected by the flight control system, so as to realize the automatic adjustment of each light source module 2.

[0038] In addition, in the multifunctional lighting fixture of the present invention, the backup controller 42 interacts with the manual emergency switch in the aircraft control room through communication signals, so that the user can directly trigger the backup controller 42 to send control commands (such as emergency lighting signals) to the light source module 2, bypassing the main controller 41, to ensure landing lighting when the communication link corresponding to the main controller 41 fails; at the same time, the working status of each light source module 2 is synchronized through communication signals to ensure the uniformity and consistency of the light field.

[0039] Therefore, the multifunctional lamp of the present invention adopts a "three-way power supply scheme + distributed control + synchronous control" architecture, which can realize highly reliable aircraft landing lighting function.

[0040] See Figure 6 , Figure 6 A second embodiment of the multifunctional lamp of the present invention is shown, and... Figure 1 Unlike the first embodiment shown, in this embodiment, the multi-functional lamp also includes a mounting bracket 5 connected to the face ring module 1. The mounting bracket 5 is used to fix the multi-functional lamp to an external device 6 (such as an aircraft).

[0041] In this embodiment, the mounting bracket 5 includes a first mounting bracket and a second mounting bracket respectively disposed on both sides of the face ring module 1; wherein, the top of the first mounting bracket and the second mounting bracket are bent toward the face ring module 1 to form a top bending portion 51, and the first mounting bracket and the second mounting bracket are fixed to the face ring module 1 through the top bending portion 51; the bottom of the first mounting bracket and the second mounting bracket are bent in the opposite direction toward the face ring module to form a bottom bending portion 52, and the first mounting bracket and the second mounting bracket are fixed to the external device 6 through the bottom bending portion 52; at the same time, the partition controller 4 can be fixed on the inner side wall of the first mounting bracket or the second mounting bracket.

[0042] Therefore, the multifunctional lamp of the present invention can be fixed to the fuselage by the mounting bracket 5 to ensure stability during flight.

[0043] See Figure 7 , Figure 7 A flowchart illustrating an embodiment of the zoning control method based on a multifunctional lighting fixture of the present invention is shown, which includes: S101, the partition controller acquires aircraft and environmental data in real time; It should be noted that aircraft data and environmental data can be collected by the aircraft's built-in flight control system and sent to the zone controller; among them, the aircraft data packet contains altitude information, pitch angle information, turn angle information, and roll angle information; environmental data includes weather information.

[0044] S102, the zone controller generates control signals based on aircraft data and environmental data; The control signals include switch signals, light emission angle signals, and brightness signals. Furthermore, the control signals also include synchronization signals to ensure the synchronization of each light source module; at the same time, the control signals also include emergency lighting signals to ensure landing illumination in the event of failure of some communication links.

[0045] S103, the zone controller sends control signals to the light source module respectively to control the working status of each light source in the light source module.

[0046] Therefore, the zonal control method of the multi-functional lighting fixture of the present invention can intelligently judge the scene according to aircraft data and environmental data, and control the working status of the light source in different areas of the multi-functional lighting fixture to realize the functions of landing lights, turning lights and taxi lights; at the same time, it can also effectively ensure that when the multi-functional lighting fixture realizes the function of landing lights, the light source emitted by it always automatically keeps aligned with the runway, so as to realize targeted lighting.

[0047] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
