[0020] The present invention will be further described in detail below through specific implementation manners in conjunction with the attached drawings. It should be noted here that the description of these implementation manners is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Please refer to Figures 1 to 3 , what is shown in the figure is a navigation light in a friendly mode, which is installed in the left and right wingtip areas outside the aircraft and is used to indicate the position, attitude and flight direction of the aircraft in the air and on the ground.

[0022] The navigation light mainly consists of a lamp socket 1 of the lamp, a lamp cover 2 of the lamp, a fixing pressing plate 3, a light source component 4, a control printed board component 5, etc.

[0023] The lamp socket 1 of the lamp is a cylindrical barrel arranged vertically. The lamp socket 1 of the lamp defines a lamp socket accommodation space 10 that penetrates up and down. An upper mounting platform 11 is formed at the upper part of the lamp socket 1 of the lamp. An installation fixing plate 13 is also formed at the upper part of the lamp socket 1 of the lamp. The installation fixing plate 13 is integral with the upper mounting platform 11 and extends backward. The installation fixing plate 13 is fixed to the aircraft light source installation surface by screws, thereby mounting the lamp socket 1 of the lamp on the aircraft. In order to buffer vibration, a shock-absorbing pad can also be provided between the installation fixing plate 13 and the aircraft light source installation surface. A middle mounting platform 12 is formed at the middle part of the lamp socket 1 of the lamp.

[0024] The lamp cover 2 of the lamp is a hemispherical transparent shell with a downward opening. The lamp cover 2 of the lamp is arranged on the upper mounting platform 11 of the lamp socket 1 of the lamp. While the lamp cover 2 of the lamp is used for light transmission, it also reduces the wind resistance during flight. A lamp cover accommodation space 40 is defined inside the lamp cover 2 of the lamp.

[0025] The fixed pressing plate 3 is arranged on the mounting fixing plate 13. The fixed pressing plate 3 is fixedly connected to the mounting fixing plate 13 by screws. The fixed pressing plate 3 is used to fix the lamp shade 2. The fixed pressing plate 3 includes heat dissipation fins and adopts a streamline design. The heat dissipation fins are of aircraft aerodynamics and can be used to further reduce wind resistance. At the same time, at least one weight reduction groove 30 is formed on the fixed pressing plate 3 to effectively reduce the overall weight.

[0026] The light source component 4 is arranged inside the lamp shade accommodating space 40. The light source component 4 is composed of a light source substrate 41, a light source mounting seat group 42, an LED component group 43, a reflector 44 and a filter 45.

[0027] The light source substrate 41 is fixed on the upper mounting platform 11 of the lamp socket 1 of the lamp. The light source substrate 41 separates the lamp shade accommodating space 40 from the lamp socket accommodating space 10. Designed in this way, it not only meets the requirements of light performance distribution but also can conduct heat to the lamp socket 1 of the lamp to ensure better heat dissipation performance.

[0028] The light source mounting seat group 42 is arranged on the top surface of the light source substrate 41. The light source mounting seat group 42 has a first light source mounting seat 421, a second light source mounting seat 422, a third light source mounting seat 423 and a fourth light source mounting seat 424 which are arranged at intervals in sequence from front to back.

[0029] The LED component group 43 has a first LED component 431, a second LED component 432, a third LED component 433 and a fourth LED component 434.

[0030] The first light source mounting seat 421 has a first light source mounting surface. The first light source mounting surface is an inclined plane that is lower in the front and higher in the back. The first LED component 431 is arranged on the first light source mounting surface. The light-emitting beam of the first LED component 431 is distributed in the first partial area within the effective coverage range required by the navigation light distribution.

[0031] The second light source mounting seat 422 has a second light source mounting surface. The second light source mounting surface is an inclined plane that is lower in the front and higher in the back and the slope of the second light source mounting surface is greater than the slope of the first light source mounting surface. The second LED component 432 is arranged on the second light source mounting surface. The light-emitting beam of the second LED component 432 is distributed in the second partial area within the effective coverage range required by the navigation light distribution.

[0032] In this embodiment, the light-emitting beams of the first LED component 431 and the second LED component 432 are distributed in the range of 40 - 130° within the effective coverage range required by the navigation light distribution.

[0033] The third light source mounting seat 423 has a third light source mounting surface. The third light source mounting surface is an inclined plane that is lower in the front and higher in the rear, and the slope of the third light source mounting surface is greater than the slope of the second light source mounting surface. The third LED component 433 is arranged on the third light source mounting surface. The light-emitting beam of the third LED component 433 is distributed in the third partial area within the effective coverage range required by the navigation light distribution. In this embodiment, the light beam of the third LED component 433 is distributed within the range of 20-40° in the effective coverage range required by the navigation light distribution.

[0034] The fourth light source mounting seat 424 has a fourth light source mounting surface. The fourth light source mounting surface is a vertical surface. The fourth LED component 434 is arranged on the fourth light source mounting surface. The fourth LED component 434 is configured with a reflector 44. The reflector 44 distributes the light-emitting beam of the fourth LED component 434 in the fourth partial area within the effective coverage range required by the navigation light distribution. In this embodiment, the light beam of the fourth LED component 434 is distributed within the range of 0-20° in the effective coverage range required by the navigation light distribution.

[0035] The control printed circuit board component 5 is arranged inside the lamp socket accommodation space 10. The control printed circuit board component 5 is fixed to the middle mounting platform 12 by screws. Since the control printed circuit board component 5 is arranged inside the lamp socket accommodation space 10, a sealed effect is formed, which can avoid being adversely affected by natural environments such as humidity and heat. Please refer to Figure 4 , the control printed circuit board component 5 is used to control the operation of the LED component group 43. The first LED component 431, the second LED component 432, the third LED component 433, and the fourth LED component 434 work independently of each other without interference. With the control of the control printed circuit board component 5, different driving currents of different magnitudes can be provided for the first LED component 431, the second LED component 432, the third LED component 433, and the fourth LED component 434 to meet the light-emitting requirements of different LED components. Moreover, according to the actual in-aircraft mission requirements, different overall current magnitudes can be provided as a whole to achieve different light intensity requirements for the bright state and the dark state of the navigation lights. And in the flashing state, an on-off switching with a flashing frequency of approximately (85 ± 15) times per minute is provided. To meet specific mission requirements, the light intensity in the dark state and the frequency in the flashing state can also be set to other values.

[0036] The first LED component 431 (the second LED component 432, the third LED component 433, or the fourth LED component 434) uses visible light LEDs and / or infrared light LEDs. The light emission color of the first LED component 431 (the second LED component 432, the third LED component 433, or the fourth LED component 434) is ensured by the light emission color of the chips of the LEDs used.

[0037] Furthermore, both the first LED component 431 and the second LED component 432 are configured with the color filters. Through the filtering function of the color filters, the light emission requirements for the light intensity distribution and irradiance intensity distribution in the friendly mode are achieved.
