[0043] An embodiment of the present application provides a helicopter rotor wingtip light.

[0044] like Figures 1 to 6 As shown, a helicopter rotor wing tip light comprises a mounting plate 2, a lampshade 1, a base 5 and a light emitting mechanism.

[0045] The mounting plate 2 is used to be connected to the helicopter rotor wing tip through a first screw. A groove 22 is provided on a first side surface 27 of the mounting plate 2 facing the helicopter rotor wing tip. The groove 22 has a light-through hole 21 in its body.

[0046] like Figure 2 As shown, the lampshade 1 is a transparent structure, and the lampshade 1 includes a pressure plate 11 and a protruding plate 12 that are connected to each other. The protruding plate 12 is located in the middle of the pressure plate 11, and the pressure plate 11 and the bottom of the groove 22 around the light-through hole 21 are abutted, and the protruding plate 12 is located in the light-through hole 21.

[0047] The base 5 is located in the groove 22 , and is connected to the mounting plate 2 via a second screw 54 . The pressure plate 11 is located between the base 5 and the bottom of the groove 22 . A receiving groove 51 is provided on the side of the base 5 facing the lampshade 1 .

[0048] The light-emitting mechanism is located in the receiving groove 51 , and the light-emitting mechanism emits light through the lampshade 1 .

[0049] Among them, Figure 3 and Figure 4 As shown, the side walls of the groove 22 are provided with a plurality of protrusions 23 protruding toward the center of the groove 22, the edges of the base 5 and the pressure plate 11 are provided with recessed portions that cooperate with the protrusions 23, and the protrusions 23 are provided with a first threaded countersunk hole 24 for the first screw to pass through, and the part of the first threaded countersunk hole 24 that accommodates the head of the first screw is located on the side away from the first side surface 27.

[0050] The groove bottom of the groove 22 is provided with a mounting post 25, and the pressure plate 11 is provided with a mounting hole for the mounting post 25 to pass through. Figure 5 and Figure 6 As shown, the base 5 is provided with a mounting recessed hole 52 for accommodating the end of the mounting column 25 on the side facing the lampshade 1, and a second threaded countersunk hole 53 for the second screw 54 to pass through is provided on the base 5, and the second threaded countersunk hole 53 is connected to the mounting recessed hole 52, and the part of the second threaded countersunk hole 53 accommodating the head of the second screw 54 is located on the side away from the lampshade 1, and the end surface of the mounting column 25 facing away from the bottom of the groove 22 is provided with a threaded hole 26 threadedly connected to the second screw 54, and the end of the threaded hole 26 facing away from the first side surface 27 is closed.

[0052] The present application uses sealant to seal between the mounting plate 2 and the lampshade 1 and between the mounting plate 2 and the base 5. The installation of the helicopter rotor wing tip light and the helicopter rotor surface of the present application is connected by the mounting plate 2 and the first screw, and the first screw is located at the outer edge of the lampshade 1 and the base 5. The first screw only passes through the mounting plate 2 to prevent external moisture from entering the groove 22 through the gap between the first screw and the mounting plate 2, thereby improving the sealing of the helicopter rotor wing tip light and reducing the failure rate of the light-emitting mechanism; the connection between the base 5 and the mounting plate 2 is achieved by the second screw 54, and the end of the mounting column 25 away from the head of the second screw 54 is closed. The threaded connection of the second screw 54 and the mounting plate 2 is achieved through the mounting column 25, so that the exposed surface of the mounting plate 2 is closed at the position corresponding to the second screw 54, thereby preventing external moisture from entering the interior through the top of the threaded structure of the base 5 and the mounting plate 2. At the same time, sealant is applied to the head of the second screw 54 to seal the connection position of the second screw 54 and the base 5, thereby preventing external moisture from entering the interior through the bottom of the threaded structure of the base 5 and the mounting plate 2.

[0053] The mounting plate 2 adopts an integral countersunk through-hole design at the screw mounting position on the machine, avoiding the disadvantage of poor sealing caused by separate drilling and countersinking of the plate, lampshade 1 and base 5. The sealant ensures sealing and plays a shock-absorbing role.

[0054] The second side surface of the mounting plate 2 facing away from the first side surface 27 , the side surface of the protruding plate 12 of the lampshade 1 facing away from the mounting seat and the helicopter rotor surface are designed to conform to each other.

The light guide plate 8 is provided with a plurality of light outlet holes 82 distributed in an array and parallel to the first direction.

[0060] A reflective paper 7 is provided on the side of the light guide plate 8 facing away from the lampshade 1, and the reflective surface of the reflective paper 7 faces the light guide plate 8.

After the light guide plate 8 is simulated and optimized using SPEOS software, the shape of the light receiving slots 81 of the light guide plate 8 corresponding to the placement position of each LED lamp and the distribution and depth of the matrix light emitting holes 82 are obtained to ensure the uniformity of the light output. The visible light LED lamp 61 emits visible light, and the infrared LED lamp 62 emits infrared invisible light.

[0062] The visible light LED lamp 61 and the infrared LED lamp 62 are LED light-emitting diodes.
