The airport beacon of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 to FIG. 7 , an airport beacon provided according to an embodiment of the present invention can be used in a civil airport, a military airport, a helicopter airport, etc., as a special navigation aid for an airport, and is mainly used to indicate an airport to an airborne aircraft. The location and all or part of a particular area on the site or structure for aircraft take-off, landing, and surface activity includes a power box 10, a base 20, a shade 30, an upper cover 50, and an LED lighting unit 40.

Specifically, the power supply box 10 is provided with a driving control board 11 disposed on the power box 10 and rotatable in a vertical direction by a predetermined angle. The lamp cover 30 is mounted on the base 20, and the upper cover 50 is mounted on the upper end of the lamp cover and defines a sealed receiving cavity together with the lamp cover and the base. The LED lighting unit 40 is mounted in the receiving cavity and is electrically connected to the driving control board 11 to operate under the driving of the driving control board 11.

According to the airport beacon provided by the embodiment of the present invention, the LED lighting unit 40 is used as the light source, and the lamp is highly efficient. Long life of light source, low maintenance cost, energy saving and environmental protection. In addition, the base 20 is disposed on the power box 10 and can be rotated by a predetermined angle in the vertical direction, that is, the LED lighting unit 40 can be rotated by a predetermined angle. Thus, the angle of the LED lighting unit 40 can be adjusted to meet different orientation observations. .

Optionally, the base 20 and the power box 10 can be made of metal. For example, the base 20 is made of aluminum alloy, which has high structural strength, corrosion resistance, can adapt to the harsh outdoor environment, and has good heat conduction performance. The heat of the LED lighting unit 40 is quickly transmitted to the outside, which accelerates heat dissipation and improves heat dissipation. The power box 10 is made of stainless steel and has high structural strength and corrosion resistance. It can be used in outdoor harsh natural environments and is easy to process.

Referring to FIG. 1 to FIG. 2, in one embodiment of the present invention, the lamp cover 30 is formed in an annular cylindrical shape, the upper end of the lamp cover 30 is open to form a first opening, and the lower end of the lamp cover 30 is open to form a second opening. The upper cover 50 seals the first opening, and the base 20 seals the second opening, that is, the lamp cover 30 has an annular cylindrical structure, and the upper and lower ends are open, and the upper cover 50 is detachably connected to the lamp cover 30. The upper end is for sealing the first opening of the upper end of the lamp cover 30, and the base 20 is detachably connected to the lower end of the lamp cover 30 to seal the second opening of the lower end of the lamp cover 30. Thus, the structure is simple, the assembly is convenient, and the seal can be sealed. The above-mentioned receiving cavity is formed, and the sealing effect is good.

For example, as shown in FIG. 3, the LED lighting unit 40 includes an upper fixing plate 402, a lower fixing plate 403, and a plurality of LED light source assemblies 401. The plurality of LED light source assemblies 401 are fixed to the upper fixing plate 402 and fixed. The plates 403 are enclosed and formed into a polygonal shape, and the light-emitting directions of the respective LED light source assemblies 401 are directed toward the globe 30 to form the ring illumination.

That is, the LED lighting unit 40 is mainly composed of an upper fixing plate 402, a lower fixing plate 403 and a plurality of LED light source assemblies 401, wherein the plurality of LED light source assemblies 401 are surrounded by a polygonal structure and passed through the upper fixing plate 402 and The lower fixing plate 403 is fixed. For example, in the example of FIG. 3, the four LED light source assemblies 401 are enclosed to form a quadrilateral structure. Thus, the four LED light source assemblies 401 respectively emit light in different directions to form four light emitting surfaces arranged in a circumferential direction. The emitted light passes through the lampshade 30 and exhibits a ring-lighting effect, so that the airport beacon can be observed at different angles, and the indication effect is better.

It should be noted that the present invention is not limited thereto, and the number of the LED light source components 401 may be configured as needed, for example, a polygonal structure formed by enclosing five, six or more LED light source components 401, for example, five LED light sources. The component 401 is enclosed to form a pentagonal structure, and the six LED light source components 401 are enclosed to form a hexagonal structure. The more the number of the LED light source components 401, the more the light surface is formed, and the better the ring light effect is formed.

Referring to FIG. 4, in an embodiment of the present invention, each of the LED light source assemblies 401 includes a reflector 4011, a strip heat sink 4012, a light source substrate 4013, and a plurality of LED light sources 4014, and a strip heat sink 4012. The light-receiving cover 4011 is relatively fixed in the front-rear direction; the light source substrate 4013 is disposed on the strip-shaped heat sink 4012; The LED light sources 4014 are arranged on the light source substrate 4013 in a linear array, and the light emitting directions of the LED light sources 4014 are all directed toward the reflector 4011, and the light emitting axis lines of the LED light sources 4014 are parallel to each other. The light emitted from the LED light source 4014 is reflected by the reflector 4011 and then emitted from the globe 30.

For example, in the example of FIG. 4, the strip heat sink 4012 is disposed in parallel with the front of the reflector 4011. The strip heat sink 4012 may be an aluminum profile. The light source substrate 4013 is mounted on the rear surface of the strip heat sink 4012, and the plurality of LED light sources 4014. Arranged on the light source substrate 4013 in a linear array manner, and each of the LED light sources 4014 is directed toward the reflector 4011. Thus, when the LED light source 4014 is illuminated, the light of the LED light source 4014 is projected to the reflector 4011 due to the reflector 4011. Since it has an optical reflection effect, the light projected onto the reflector 4011 is concentratedly reflected to the front by the reflection of the reflector 4011, and finally emitted from the globe 30.

In other words, the light emitted by the LED light source is reflected by the reflector 4011 and then emitted from the lamp cover 30, which can improve the conversion rate of the light source, and make the emitted light more concentrated and uniform, and the light intensity is stronger, and can meet the high light intensity requirement indicated by the airport.

More specifically, referring to FIG. 4 to FIG. 5, in one example, the reflector 4011 includes a bottom wall and a first side wall 4011b and a second side wall 4011c, wherein the bottom wall extends in the left-right direction, the bottom wall A central bottom wall 4011a, an upper edge bottom wall 4011g formed on an upper side of the central bottom wall 4011a, and a lower edge bottom wall 4011h formed on a lower side of the central bottom wall 4011a; the central bottom wall 4011a is formed to be rearward a convex arc shape, the upper edge bottom wall 4011g and the lower edge bottom wall 4011h are formed in a straight line or an arc shape; the first side wall 4011b is formed on a left side of the bottom wall, the second side wall 4011c is formed on the right side of the bottom wall.

When the LED light source emits light, the light is projected onto the central bottom wall 4011a of the reflector 4011, the upper edge bottom wall 4011g, and the lower edge bottom wall 4011h, and is reflected by the center bottom wall 4011a, the upper edge bottom wall 4011g, and the lower edge bottom wall 4011h. Specifically, since the central bottom wall 4011a is an arc that protrudes rearward, part of the light is reflected by the central bottom wall 4011a, and is concentrated toward the center to form uniform reflected light from the globe 30. At the same time, another portion of the light projected onto the central bottom wall 4011a is once reflected by the central bottom wall 4011a, and then reflected to the upper edge bottom wall 4011g or the lower edge bottom wall 4011h, and then passes through the upper edge bottom wall 4011g or the lower edge. The secondary reflection of the bottom wall 4011h is concentrated to form a uniform reflected light that is emitted from the globe 30. Further, the first side wall 4011b and the second side wall 4011c also function as reflections, and the light reflection on both sides can be accumulated in the middle and emitted from the globe 30. In this way, the reflection effect can be improved, and the light is more concentrated and more uniform.

Referring to FIG. 6 , more specifically, the light source substrate 4013 is printed with a line corresponding to the LED light source 4014 and an LED power contact point and a wire power contact point 4013a on the line. The LED light source 4014 is connected to the device. At the LED energization contact, the wire energizing contact 4013a is connected to the power supply wire 4015, and thus, through the power supply guide The line 4015 is connected to direct current, and the direct current is supplied to each of the LED light sources 4014 through the line, so that the LED light source 4014 operates.

Optionally, the reflector 4011 can be made of optical grade PC material, which has good anti-aging and anti-shock effects, so as to adapt to the harsh natural environment outside.

More preferably, the inner surface of the central bottom wall 4011a is formed with a reflective rib 4011d extending in the left-right direction at an intermediate position in the up-and-down direction, the reflective rib 4011d being opposite to the plurality of LED light sources, and the reflective rib 4011d The longitudinal section is formed as a triangle that protrudes in a direction close to the LED light source. That is, the reflecting rib 4011d formed on the inner surface of the center bottom wall 4011a is protruded forward and has a triangular cross section in the longitudinal direction.

Since the light source substrate 4013 and the strip heat sink 4012 in front of the reflector 4011 have a certain width in the up and down direction, the light emitted from the LED light source 4014 is projected on the bottom wall of the reflector 4011, and part of the light is projected onto the central bottom wall 4011a. The light source substrate 4013 and the strip heat sink 4012 are opposite to each other. After the light is reflected by the central bottom wall 4011a, a part of the light is blocked by the light source substrate 4013 and the strip heat sink 4012. Thus, the light source is lost and the light conversion rate is lowered. , brightness reduction and other issues.

To this end, in the present embodiment, by providing the reflecting edge 4011d on the central bottom wall 4011a of the reflector, the light that is partially projected onto the reflecting edge 4011d is a triangular shape that protrudes forward because the longitudinal section of the reflecting edge 4011d is Therefore, the plane where the two sides of the triangle are located is the inclined surface S10, and the portion of the light is reflected by the inclined surface S10, and then the secondary reflection is performed through the upper edge bottom wall 4011g and the lower edge bottom wall 4011h, thereby finally avoiding the light source substrate. 4013 and a strip radiator 4012 are ejected from the globe 30. In other words, the light partially projected onto the reflecting edge 4011d can be finally emitted from the globe 30 by two reflections, so that the light source loss can be reduced, the light conversion rate can be further increased, and the light intensity can be enhanced.

It can be understood that the plane where the two sides of the triangle are located may be a plane or a curved surface, and may be set as needed.

In order to facilitate the fixing of the respective LED light source assemblies 401, a corresponding fixing structure may be disposed on each of the LED light source assemblies 401.

Therefore, the horizontal angle of the LED lighting unit 40 and the lamp cover 30 can be adjusted by rotating the base 20. Specifically, the lock nut is first rotated in one direction, so that the lock nut leaves the base 20, and at this time, the positioning post 1021 is released. Relatively locking with the sliding hole 202, the base 20 is rotated, so that the base 20 and the LED lighting unit 40 and the lamp cover 30 thereon are rotated to a desired angle.
