Description

Technical Field

[0001] This utility model belongs to the technical field of aircraft external formation signal lights, and specifically relates to a formation light device structure with control circuit. Background Technology

[0002] With the continuous advancement of aviation technology and the increasing complexity of flight missions, the application of formation lights on various types of aircraft is becoming increasingly widespread. Whether in the civil aviation sector to ensure the safe and orderly flight of aircraft formations, or in the military aviation sector to assist fighter jet formations in performing diverse combat missions, formation lights play an indispensable and important role.

[0003] Traditional formation lights, commonly seen in daily life, have some obvious limitations in design and construction. Internally, they lack independent control circuitry, making it impossible to autonomously control diverse functions such as brightness adjustment and flashing mode switching. Their housings are typically made of non-metallic materials using die-casting, which, while meeting basic molding requirements to some extent, offers poor anti-interference performance. During flight, aircraft face various complex electromagnetic environments; numerous surrounding electronic devices and external electromagnetic radiation can interfere with the formation lights, causing instability, abnormal flashing, and inconsistent brightness, severely impacting the visual recognition of flight formations.

[0004] Furthermore, non-metallic casings pose significant safety risks in terms of lightning protection. Aircraft are vulnerable to lightning strikes during flight, especially in thunderstorms or when passing through clouds. When lightning strikes an aircraft, the powerful current is instantly conducted to all its components. Utility Model Content

[0035] This embodiment presents a formation light structure design with a control circuit. Figure 3 The exploded view shows the following components: countersunk screw 1, lamp cover 2, conductive sealing ring 3, sealing ring 4, lampshade 5, Phillips head pan screw 6, spring washer 7, washer 8, light-emitting module 9, housing 10, micro rectangular socket 11, inner housing 12, washer 15, spring washer 16, nut 17, countersunk screw 18, base plate 19, conductive sealing gasket 20, filter 21, spring washer 23, flat washer 24, main control board assembly 25, socket gasket 26, cylindrical head screw with safety hole 27, socket 28, and socket bracket 29.

[0036] The aforementioned formation light structure design with control circuitry includes a housing assembly such as... Figure 4As shown, the lampshade 5 is mounted on the housing 10 via the lamp cover 2 and the sealing ring 4, with a conductive rubber pad and conductive sealing ring 3 placed in between. The lamp cover 2 is fixed with countersunk screws 1 through four threaded holes. The light-emitting module 9 is mounted and fixed on the housing 10 via four sets of screws 6, spring washers 7, and flat washers 8.

[0037] The housing 10 is made of high-strength aluminum alloy and is precision die-cast or milled. From the head to the tail, the housing 10 has a gradually decreasing slope. In order to better fit with the aircraft and reduce the impact of wind resistance outside the cabin, the bottom surface of the housing 10 is at a 20° angle to the horizontal plane. The cross-section of the housing is designed as an arc shape, and the overall shape of the housing is streamlined. The inner cavity of the housing is designed to remove material to meet the installation requirements of the inner housing 12 of the main control board assembly 25 inside the housing. The wall thickness of the housing has been optimized to reduce weight while meeting the mechanical strength requirements of the external products of the aircraft cabin. The inner cavity of the housing has a ring of bosses with 10 threaded holes for mounting the conductive sealing gasket 20 and the base plate 19. The conductive sealing gasket 20 is installed between the base plate 19 and the ring of bosses to provide a seal. The outer frame of the housing 10 has an overlap design with 7 circular mounting holes for mechanical interface installation on the machine. The larger end of the housing 10 is milled flat, with 4 threaded holes around the end face for mounting and fixing the lamp cover 2. The lamp cover 2 and the larger end face of the housing are sealed by pressing with an O-ring conductive seal 3, which is installed by creating a circular groove on the back of the lamp cover.

[0038] The aforementioned formation light structure design with control circuit includes a lamp cover assembly comprising a lamp cover 2, a sealing ring 4, a lamp shade 5, a conductive sealing ring 3, a light-emitting module 9, a housing 10, an inner housing 12, a main control board assembly 25, a micro rectangular socket 11, a base plate 19, a socket bracket 29, a socket 28, and a socket gasket 26.

[0039] The lamp cover 2 is a plate-shaped structure with an arched shape. A stepped circular hole is machined in the middle part for embedding the formation light cover 5. The circular hole is surrounded by circular steps for fitting and fixing to the edge of the light cover 5. In order to ensure sealing and prevent the glass light cover from being scratched, a circular sealing ring 4 is installed on the circular steps on the inner side of the lamp cover 2.

[0040] The sealing ring 4 is a 0.5mm thick annular silicone rubber pad. Its function is to ensure the seal between the lamp cover 2 and the lamp shade 5, preventing atmospheric moisture and other substances from entering the formation lights.

[0041] The lampshade 5 is integrally ground from a single piece of highly transparent, colorless optical glass. Its shape is a spherical convex form with a hollow interior, and the surface of the glass lampshade is treated with a coating process. The brightness signal of the light is not weakened by the addition of the glass shade. A raised ring is for mate installation with the lamp cover 2 and the sealing ring 4.

[0042] The light-emitting module 9 is a circular light panel assembly. It has two colors for night vision: red and white. It can receive color control commands from the control board assembly and display the corresponding color light signal; it can receive night vision compatible control commands from the control board assembly and keep the infrared light on or flash the infrared light at a specific frequency; it can receive light control commands from the control board assembly and adjust the brightness of the signal light.

[0043] The edge of the light-emitting module is designed with four circular mounting holes. In order to reduce the length of the screws used, the mounting holes of the light-emitting module 9 are designed to be about 1 / 3 the thickness of the module, so that the light-emitting module 9 can be installed in the mounting hole at one end of the housing 10.

[0044] Inner housing components such as Figure 5 As shown, the socket 28 is mounted on the socket bracket 29 and is fixed to the main control board assembly 25 by four sets of screws 22, spring washers 23, and flat washers 24. The main control board assembly 25 is fixed to the threaded holes of four bosses inside the inner housing 12 by four sets of screws 22, spring washers 23, and flat washers 24; the filter 21 is fixed to the corresponding position of the inner housing 12 by two sets of screws 14, spring washers 16, flat washers 15, and nuts 17; the micro-rectangular socket 11 is fixed to the corresponding position of the side wall of the inner housing 12 by its own screws; and the conductive sealing ring 3 is fixed to the sealing groove of the inner housing 12.

[0045] The inner housing 12 is a regular rectangular box that fits inside the cavity of the housing 10. It is made of high-strength aluminum alloy, die-cast or machined by material removal. One-piece machining facilitates sealing and electromagnetic leakage prevention. The bottom of the inner housing 12 has four mounting bosses, each with a threaded hole at its center for mounting and fixing the main control board assembly 25. The edges of the inner housing 12 have conductive sealing grooves for installing conductive sealing rings 3, which resist moisture intrusion, electromagnetic interference, and corrosion. Eight threaded holes around the perimeter of the inner housing 12 are for mounting and fixing to the base plate 19.

[0046] The main control board assembly 25 is designed to fulfill the control functions of the formation lights. It can display corresponding colored lights according to received color control commands; it can receive night vision compatible control commands and continuously illuminate infrared light or flash infrared light at a specific frequency; it can adjust the brightness of the signal lights according to received light control commands; and it has a self-test function. The main control board assembly 25 is installed inside the inner housing 12.

[0047] The main function of the micro-rectangular socket 11 is to connect the light-emitting module 9 and the main control board assembly 25. The micro-rectangular socket 11 is fixed to the side wall of the inner housing 12 by its own screws, and the plug that matches it is soldered to the wires led out from the light-emitting module 9. This ensures that the light-emitting module 9 and the main control board assembly 25 are connected, thereby controlling the brightness and type of the formation lights.

[0048] The base plate 19 is a thin aluminum alloy plate, whose main function is to cooperate with the housing 10 for installation and to serve as the mounting point for the circular socket 28.

[0049] The socket bracket 29 is used to connect and support the main control board assembly 25 and the socket 28.

[0050] The socket gasket 26 is installed between the base plate 19 and the circular socket 28 to provide a seal.
