Description

Technical Field

[0001] The utility model relates to the field of tail navigation lights, and in particular to a novel integrated tail navigation light developed by adopting an LED light source. Background Art

[0002] An airplane refers to an aircraft that is heavier than air and has wings and one or more engines, and can fly in the atmosphere by its own power. A tail navigation light refers to a group of signal lights installed on an airplane for air traffic to find each other and determine the direction of flight during navigation. It is used to indicate the heading and position of the aircraft. Generally speaking, a red light is installed on the tip of the left wing, a green light is installed on the tip of the right wing, and a white light is installed on the tail end.

[0003] Most of the existing tail navigation lights use incandescent bulbs. Since the light source of incandescent bulbs is a tungsten filament structure, and the tungsten filament has a short life at high temperatures and low vibration resistance, there are many problems with such tail navigation lights during use. Therefore, those skilled in the art have provided a new integrated tail navigation light developed using an LED light source to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and it is proposed to develop a new integrated tail navigation light using LED light source. The product adopts a new high-power LED lighting source, the color is aviation white, the service life can be up to tens of thousands of hours, the lamp power is less than 5W, the mechanical and electrical interfaces of the lamp adopt a universal interface compatible with the original incandescent bulb type tail navigation light, and a non-imaging heterogeneous design is adopted in the spatial light distribution, which can meet the requirements of light distribution in space. The product design mainly includes optical design, circuit design, appearance and interface design.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A new integrated tail navigation light is developed using LED light source, including a light housing and a conversion potentiometer, wherein a top light source board assembly is fixedly arranged inside the upper end of the light housing, and a driving board assembly is fixedly arranged inside the lower end of the light housing;

[0007] The conversion potentiometer circuit is connected with a lightning protection module, a protection diode, a resistor and an LED lamp bead;

[0008] Through the above technical solution, the tail navigation light adopts LED light source to develop an integrated tail navigation light, which can solve the shortcomings of the previous tail navigation light using incandescent light source, so that the product has good environmental adaptability, life, power saving and reliability. When in use, the lamp housing can be used to protect the internal circuit, the conversion potentiometer plays a role in regulating the voltage and controlling the current, the top light source board assembly plays a role in lighting, and the drive board assembly plays a role in controlling the operation of the tail navigation light. When the onboard power supply is supplied, the conversion potentiometer is connected in series with the resistor and lamp bead in the navigation light. When a reverse pulse appears at the negative end When high voltage is applied, the protection diode quickly restores the diode conduction to prevent the high voltage pulse from impacting the LED lamp beads. When high voltage appears in the lightning attachment area and affects the lighting equipment, the lightning protection module can "absorb" the instantaneous high voltage to prevent the impact of lightning. When the voltage fluctuates between 18 and 32V, the voltage divider value in the resistor will increase or decrease accordingly, causing the voltage at the LED lamp bead end to remain relatively stable. In this way, the lamp can work normally when the external voltage fluctuates. When the external brightness adjustment is required, the resistance value of the external series potentiometer changes, causing the voltage at the lamp bead end to change accordingly, achieving compatibility with the brightness dimming of the original tail navigation light.

[0009] Furthermore, a fixed lamp ring is threadedly arranged on the upper end of the lamp housing, and a transparent lampshade is fixedly arranged on the upper end of the fixed lamp ring;

[0010] Through the above technical solution, the fixed lamp ring plays a role of lighting, and the transparent lampshade plays a role of protecting the fixed lamp ring.

[0011] Furthermore, a waterproof rubber pad is fixedly arranged inside the transparent lampshade;

[0012] Through the above technical solution, the waterproof rubber pad plays a waterproof role and can also provide waterproof protection for the fixed lamp ring.

[0013] Furthermore, a plurality of side light source panel assemblies are fixedly arranged at an upper position of the outer surface of the lamp housing;

[0014] Through the above technical solution, the side light source panel assembly also plays a role in lighting.

[0015] Furthermore, a lower lamp housing is fixedly provided at the lower end of the lamp housing;

[0016] Through the above technical solution, the housing under the lamp ensures the overall sealing of the tail navigation light and plays a role in sealing protection.

[0017] Furthermore, an electrical connector is fixedly provided at the lower end of the lower housing of the lamp, and second cross-slot pan head screws are threadedly sleeved at the four corners of the lower end of the electrical connector;

[0018] Through the above technical solution, the electrical connector serves to connect the driving board assembly with the top light source board assembly and the side light source board assembly, and the second cross-slot pan head screw serves to fix the electrical connector.

[0019] Furthermore, a cross-slot countersunk screw is provided on the threaded sleeve on the outer surface of the lamp housing;

[0020] Through the above technical solution, the cross recessed countersunk screw plays a role in connecting the lamp housing and the lower housing of the lamp.

[0021] Further, a plurality of first cross-slot pan head screws are provided on the threaded sleeve at the lower end of the drive plate assembly;

[0022] Through the above technical solution, the first cross recessed pan head screw plays a role in fixing the drive plate assembly.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-4 The utility model provides an embodiment: a new integrated tail navigation light is developed by using LED light source, including a lamp housing 5 and a conversion potentiometer 13, a top light source board assembly 4 is fixedly arranged inside the upper end of the lamp housing 5, and a driving board assembly 7 is fixedly arranged inside the lower end of the lamp housing 5; the conversion potentiometer 13 circuit is connected with a lightning protection module 14, a protection diode 15, a resistor 16 and an LED lamp bead 17.

[0034] When in use, the tail navigation light is protected by the lamp housing 5 that is provided. The lamp housing 5 is made of aviation aluminum alloy material, is lightweight, and is resistant to collision and impact. When in use, the voltage is adjusted and the current is controlled by the conversion potentiometer 13, and the top light source panel assembly 4 is controlled to operate through the provided driving board assembly 7, and lighting is performed through the top light source panel assembly 4. When the onboard power supply is supplied, the conversion potentiometer 13 is connected in series with the resistor 16 and the LED lamp bead 17 in the navigation light. When a reverse pulse high voltage appears at the negative end, the protection diode 15 quickly restores the diode conduction to prevent the high-voltage pulse from impacting the LED lamp bead 17. When high voltage appears in the lightning attachment area and affects the lighting equipment, the lightning protection module 14 can "absorb" its instantaneous high voltage to prevent the impact of lightning.

[0035] Reference Figure 1-3 A fixed lamp ring 1 is threadedly provided on the upper end of the lamp housing 5, a transparent lamp cover 3 is fixedly provided on the upper end of the fixed lamp ring 1, a waterproof rubber pad 2 is fixedly provided inside the transparent lamp cover 3, a plurality of side light source panel assemblies 6 are fixedly provided on the upper position of the outer surface of the lamp housing 5, a lower lamp housing 8 is fixedly provided on the lower end of the lamp housing 5, an electrical connector 9 is fixedly provided on the lower end of the lower lamp housing 8, and a second cross slot pan head screw 12 is threadedly sleeved on the four corners of the lower end of the electrical connector 9.

[0036] The tail navigation light can protect the fixed light ring 1 through the transparent lamp cover 3 and illuminate through the fixed light ring 1. The fixed light ring 1 can be waterproofed by the waterproof rubber pad 2. The side light source panel assembly 6 also plays a role of lighting. The overall sealing of the tail navigation light is ensured by the lower lamp shell 8. The driving board assembly 7 is connected to the top light source panel assembly 4 and the side light source panel assembly 6 through the electrical connector 9. The second cross-slot pan head screw 12 plays a role of fixing the electrical connector 9.

[0037] Reference Figure 3 A cross recessed countersunk screw 10 is threadedly sleeved on the outer surface of the lamp housing 5 , and a plurality of first cross recessed pan head screws 11 are threadedly sleeved on the lower end of the driving plate assembly 7 .

[0038] The lamp housing 5 and the lower lamp housing 8 are connected by means of cross recessed countersunk screws 10 , and the driving board assembly 7 is fixed by means of a first cross recessed pan head screw 11 .

[0039] Working principle: The tail navigation light should be able to switch between bright and dark states during use. The switching is done through the conversion knob on the control panel. The conversion potentiometer 13 is connected in series with the tail navigation light for power supply. When the bright state is required, the resistance of the conversion potentiometer 13 is switched to a low value, the voltage at the lamp end becomes higher, and the brightness of the light increases accordingly. When the dark state is required, the resistance of the conversion potentiometer 13 is switched to a high value, the voltage at the lamp end becomes lower, and the brightness of the light becomes lower accordingly. For this reason, two problems are solved in the circuit design. One is the adaptability of the brightness adjustment circuit compatible with the original tail navigation light, and the other is to adapt to the characteristics of the onboard power supply, that is, when the power supply fluctuates between 18 and 32V, the light should be able to work normally. Therefore, the circuit adopts a current-limited constant voltage drive circuit. The working principle of the tail navigation light circuit diagram is that when using When the onboard power supply is powered, the conversion potentiometer 13 is connected in series with the resistor 16 and the LED lamp bead 17 in the navigation light. When a reverse pulse high voltage appears at the negative end, the protection diode 15 quickly restores the diode conduction to prevent the high-voltage pulse from impacting the LED lamp bead 17. When high voltage appears in the lightning attachment area and affects the lighting equipment, the lightning protection module 14 can "absorb" its instantaneous high voltage to prevent the impact of lightning. When the voltage 18~32V fluctuates, the voltage divider value on the resistor 16 will increase or decrease accordingly, causing the voltage at the end of the LED lamp bead 17 to remain relatively stable. In this way, the light can work normally when the external voltage fluctuates. When the external brightness adjustment is required, the resistance value of the external series potentiometer changes, causing the voltage at the end of the LED lamp bead 17 to change accordingly, thereby achieving compatibility with the brightness dimming of the tail navigation light.
