Description

Technical Field

[0001] The invention relates to the technical field of aviation lighting, in particular to an ultra-low-type heliport floodlight. Background Art

[0002] Heliport floodlights are lighting equipment designed specifically for helicopter pads. They are used to provide floodlighting at night or in low visibility conditions, ensuring that the illumination of the apron is not lower than a certain standard, making the apron signs more recognizable and providing accurate information for helicopter landing.

[0003] According to the 2023 Civil Aviation MH5013-2023 specification, the ground height limit for floodlights at the original helicopter airport is changed from 25cm to 5cm. Therefore, in order to meet the requirements of civil aviation regulations, the 25cm floodlight needs to be produced with a height of 5cm, which changes the overall internal structure layout and poses great production difficulties.

[0004] Secondly, when using the floodlight, it is necessary to avoid the pilot from being dazzled when looking down in the air, so as to prevent the pilot from being dazzled and causing accidents. Therefore, the existing floodlights generally install a shading plate on the top of the irradiation end to block the light of the floodlight from irradiating upwards, so as to prevent the light from directly irradiating high altitudes and causing dazzle to helicopter pilots, thereby affecting flight safety. However, the civil aviation regulations require that the floodlight be produced at a height of 5 cm, which leads to the installation of the shading plate, which is difficult to be used for the 5 cm high floodlight. Therefore, a new anti-glare structure is urgently needed to adapt to the 5 cm high floodlight;

[0005] Finally, existing floodlights are generally installed close to the ground. When it rains, rainwater from the ground easily causes obstruction, resulting in water accumulation, which increases the risk of water entering the floodlights. In addition, existing floodlights use rubber ring gaskets to achieve sealing and waterproofing at the joints, and the waterproofing effect is single.

[0006] For this reason, need to design a kind of super low helicopter airport floodlight to solve the above-mentioned problem. Summary of the invention

[0007] The present invention provides an ultra-low-type heliport floodlight, which solves the above-mentioned technical problems.

[0008] In order to solve the above technical problems, the present invention provides an ultra-low helicopter airport floodlight, comprising a main housing of the floodlight with a height of 5 cm, the main housing of the floodlight is chamfered, and an installation chamber is opened in the middle of the top of the main housing of the floodlight, a convex ring is fixed on the top of the installation chamber, an EVA inner pad is placed on the top of the main housing of the floodlight, an upper cover is arranged on the upper part of the EVA inner pad, the top of the upper cover is concave and fits the convex ring, and the upper cover is fixed to the top of the main housing of the floodlight by bolts to seal the installation chamber, a plurality of concave feet are fixedly connected to the outer edge of the main housing of the floodlight, the main housing of the floodlight contacts the ground through the plurality of concave feet and is bolted, and the bottom of the main housing of the floodlight is higher than the concave feet. At the bottom of the foot, a right-angle groove is provided on one side of the outer side of the main shell of the floodlight, and a mounting groove is provided toward the inner wall of the mounting chamber. Three groups of lighting grooves are equidistantly provided inside the mounting groove and are connected to the inside of the mounting chamber. A lampshade glass is fixed with bolts inside the mounting groove, and a waterproof ring is installed between the lampshade glass and the edge of the mounting groove for sealing. The mounting chamber is provided with reinforcing rib structures fixed on both sides of each lighting groove, and three groups of focusing convex mirrors corresponding to the three groups of lighting grooves are plugged and fixed in the mounting chamber through multiple reinforcing rib structures. An aluminum substrate fixing frame is fixed in the mounting chamber, and three groups of LED lamp modules are fixed on the end face of the aluminum substrate fixing frame facing the focusing convex mirrors corresponding to the three groups of focusing convex mirrors.

[0009] Furthermore, a through-connection head is fixed inside the installation chamber, a through hole is opened on the top of the through-connection head to communicate with the outside, and the three groups of LED lamp modules are connected to external wires through the through-connection head to be powered.

[0010] Furthermore, the focusing convex mirror can refract the light emitted by the LED lamp module into parallel light.

[0011] Furthermore, there is a height difference between the inner bottom of the lighting groove and the inner bottom of the installation groove, and the inner bottom of the lighting groove is higher than the inner bottom of the installation groove.

[0012] Furthermore, the bottom surface of the groove, the top surface of the upper cover, or the outer surface of the main housing of the floodlight can be printed with a trademark logo.

[0013] Furthermore, the multiple reinforcing rib structures are divided into three groups to match the focusing convex mirrors, each group includes two reinforcing rib structures symmetrically composed, and the focusing convex mirror is inserted and installed in the two reinforcing rib structures to block the lighting slot channel.

[0014] Furthermore, the reinforcing rib structure includes L-shaped ribs and straight ribs, the L-shaped ribs are fixed at the bottom of the installation chamber, the straight ribs are fixed at one side of the heating and lighting groove of the installation chamber, and there is a gap between the L-shaped ribs and the straight ribs, and the focusing convex mirror is inserted and fixed in the gap.

[0015] Compared with the related art, the ultra-low helicopter airport floodlight provided by the present invention has the following beneficial effects:

[0016] The present invention provides that the floodlight contacts the ground of the heliport through the inner concave foot and is fixed with bolts. There is a height difference between the bottom of the inner concave foot and the bottom of the main housing of the floodlight, so that there is a gap between the main housing of the floodlight and the ground of the heliport. The natural terrain is utilized so that rainwater can smoothly flow to a lower place through the gap when it rains, effectively avoiding the problem of water accumulation caused by the obstruction of rainwater at the position of the floodlight. When a fault occurs later, the device can be repaired by removing the upper cover, which is relatively convenient.

[0017] The present invention provides a floodlight with an overall height of 5 cm and a chamfered surface, so that workers are not easily tripped when passing by, and the safety is high. In addition, a plurality of reinforcing rib structures are arranged inside the main housing of the floodlight, which greatly improves the overall load-bearing capacity and is not easily deformed.

[0018] The present invention provides that, when lighting, three groups of LED lamp modules are powered on for lighting, and a focusing convex mirror is correspondingly arranged in front of each LED lamp module. The focusing convex mirror has a focusing effect, and can focus the light emitted by the LED lamp module into a parallel light beam to emit from the lampshade glass for lighting, thereby realizing the control of the irradiation angle of the light beam, enhancing the irradiation intensity and directionality of the light, ensuring that the light is irradiated on the area requiring illumination, preventing the light from being scattered and irradiating the eyes of the staff, and greatly improving the lighting safety; and the three groups of LED lamp modules are linearly arranged for illumination, so that the illumination area is wide, and the irradiated light rays are superimposed and supplemented with each other, so that the brightness of the entire lighting area is more uniform, thereby avoiding obvious brightness differences.

[0019] The present invention provides that a convex ring is arranged at the installation chamber position on the top of the main housing of the floodlight to form a waterproof barrier. When rainwater penetrates into the interior from the gap of the upper cover, since the convex ring is higher than the top of the main housing of the floodlight, the penetrated rainwater is blocked and is difficult to enter the installation chamber, and the waterproof performance is high.

[0020] The present invention provides that a rubber waterproof ring is installed between the lampshade glass and the installation groove of the floodlight, thereby improving the sealing performance and preventing water from entering, and there is a height difference between the bottom of the installation groove and the bottom of the lighting groove, which effectively blocks rainwater from entering the installation chamber, thereby achieving double waterproofing. Finally, a focusing convex mirror is inserted between a group of reinforcing rib structures, that is, between a combination of two L-shaped ribs and a right-angle rib, to block the lighting groove channel, thereby achieving triple waterproofing and high waterproofing performance.

[0021] In summary, the installation of floodlights and their design excel in convenience, lighting control and waterproof performance, which not only improves the lighting effect, but also greatly reduces maintenance costs and safety hazards, providing efficient and safe lighting solutions for places such as heliports.

Three groups of lighting slots 16 are provided at equal intervals inside the mounting slot 15 and communicate with the inside of the mounting chamber. A lampshade glass 3 is fixed with bolts inside the mounting slot 15, and a waterproof ring 7 is installed between the lampshade glass 3 and the edge of the mounting slot 15 for sealing. A reinforcing rib structure 14 is fixed on both sides of each lighting slot 16 in the mounting chamber, and three groups of focusing convex mirrors 6 are fixed in the mounting chamber through multiple reinforcing rib structures 14 corresponding to the three groups of lighting slots 16. An aluminum substrate fixing frame 8 is fixed in the mounting chamber, and three groups of LED lamp modules 81 are fixed on the end surface of the aluminum substrate fixing frame 8 facing the focusing convex mirror 6 corresponding to the three groups of focusing convex mirrors 6.

[0028] Specifically, when installing the floodlight, open the upper cover 2 on the top of the main housing 1 of the floodlight, remove the EVA inner pad 5, insert the cable on the helicopter airport ground into the installation chamber through the through-connection head and connect it to the three LED lamp modules 81, set a rubber sleeve inside the through-connection head to keep it sealed, then cover the EVA inner pad 5 on the top of the installation chamber, and cover the upper cover 2 and fix it with bolts. The floodlight contacts the helicopter airport ground through the inner concave foot 11 and is fixed with bolts. When a fault occurs later, the upper cover 2 can be removed to repair the device, which is relatively convenient. The overall height of the floodlight is 5 cm, and the outer surface of the main housing 1 of the floodlight is chamfered, so it is not easy for staff to trip when passing by, and the safety is high. In addition, multiple reinforcing rib structures 14 are arranged inside the main housing of the floodlight, which greatly improves The overall load-bearing capacity of the floodlight is high, so it is not easy to deform. There is a height difference between the bottom of the inner concave foot 11 and the bottom of the main housing 1 of the floodlight, so that there is a gap between the main housing 1 of the floodlight and the ground of the helicopter airport, which makes use of the natural terrain so that rainwater can smoothly flow to the lower place through the gap when it rains, effectively avoiding the problem of water accumulation caused by the obstruction of rainwater at the position of the floodlight. A convex ring 12 is arranged at the installation chamber position on the top of the main housing 1 of the floodlight to form a waterproof barrier. When rainwater penetrates into the interior from the gap of the upper cover 2, since the convex ring 12 is higher than the top of the main housing 1 of the floodlight, the infiltrated rainwater is blocked and it is difficult to enter the installation chamber. The waterproof performance is high. The floodlight is located between the lampshade glass 3 and the installation groove 15. The rubber waterproof ring 7 is installed to improve the sealing and prevent water ingress;

[0029] During lighting, the three groups of linearly arranged LED light modules 81 are powered by a control cable controlled by an external control system. A focusing convex mirror 6 is arranged in front of each of the three groups of LED light modules 81. The focusing convex mirror 6 has a focusing function and can focus the light emitted by the LED light modules 81 into a parallel light beam that is emitted from the lampshade glass 3 for illumination, thereby controlling the irradiation angle of the light beam, enhancing the irradiation intensity and directionality of the light, ensuring that the light is irradiated in the area that needs to be illuminated, preventing the light from scattering and irradiating the eyes of the staff, and greatly improving the lighting safety.

[0030] Among them, a through-connection connector 13 is fixed inside the installation chamber, and a through hole is opened on the top of the through-connection connector 13 to communicate with the outside. The three groups of LED light modules 81 are connected to the external wires through the through-connection connector 13 and powered. A rubber sleeve is set inside the through-connection connector to maintain sealing.

[0031] The focusing convex mirror 6 can refract the light emitted by the LED lamp module 81 into parallel light. The focusing convex mirror 6 has a focusing effect and can focus the light emitted by the LED lamp module 81 into a parallel light beam to be emitted from the lampshade glass 3 for illumination.

[0032] The bottom surface of the slot 4 , the top surface of the upper cover 2 , or the outer surface of the main housing 1 of the floodlight can be printed with a trademark logo.

[0033] Embodiment 2, on the basis of embodiment 1, there is a height difference between the inner bottom of the lighting groove 16 and the inner bottom of the installation groove 15, and the inner bottom of the lighting groove 16 is higher than the inner bottom of the installation groove 15, and multiple reinforcing rib structures 14 are divided into three groups to adapt to the focusing convex mirror 6, each group includes two reinforcing rib structures 14 symmetrically composed, and the focusing convex mirror 6 is inserted and installed in the two reinforcing rib structures 14 to block the lighting groove 16 channel.

[0034] Specifically, there is a height difference between the bottom of the installation groove 15 and the bottom of the lighting groove 16, which effectively blocks rainwater from entering the installation chamber to achieve double waterproofing. Finally, the focusing convex mirror 6 is inserted between a group of reinforcing rib structures 14 to block the lighting groove 16 channel to achieve triple waterproofing with high waterproof performance.

[0035] Among them, the reinforcing rib structure 14 includes an L-shaped rib 141 and a straight rib 142, the L-shaped rib 141 is fixed at the bottom of the installation chamber, the straight rib 142 is fixed on one side of the heating and lighting groove 16 of the installation chamber, and there is a gap between the L-shaped rib 141 and the straight rib 142, and the focusing convex mirror 6 is inserted and fixed in the gap, and the two ends of the focusing convex mirror 6 are inserted between the combined gap of the two L-shaped ribs 141 and the right-angle ribs to block the lighting groove 16 channel. When rainwater penetrates into the interior of the lighting groove 16, the focusing convex mirror 6 can prevent rainwater from entering the installation chamber.

[0036] Working principle:

[0037] When installing the floodlight, open the upper cover 2 on the top of the main housing 1 of the floodlight, remove the EVA inner pad 5, insert the cable on the helicopter airport ground into the installation chamber through the through-connection head and connect it to the three LED lamp modules 81, set a rubber sleeve inside the through-connection head to keep it sealed, then cover the EVA inner pad 5 on the top of the installation chamber, and cover the upper cover 2 and fix it with bolts. The floodlight contacts the helicopter airport ground through the inner concave foot 11 and is fixed with bolts. When a fault occurs later, the upper cover 2 can be removed to repair the device, which is relatively convenient. The overall height of the floodlight is 5 cm, and the surface is chamfered. It is not easy for staff to be tripped when passing by, and it is highly safe. In addition, multiple reinforcing rib structures 14 are set inside the main housing 1 of the floodlight, which greatly improves the overall load-bearing capacity, so that it is not easy to deform.

[0038] During lighting, the power supply of the three groups of LED lamp modules 81 of the control cable pair is controlled by an external control system. A focusing convex mirror 6 is arranged in front of each of the three groups of LED lamp modules 81. The focusing convex mirror 6 has a focusing function and can focus the light emitted by the LED lamp module 81 into a parallel light beam to be emitted from the lampshade glass 3 for lighting, thereby controlling the irradiation angle of the light beam, enhancing the irradiation intensity and directionality of the light, ensuring that the light is irradiated on the area that needs to be illuminated, preventing the light from scattering and irradiating the eyes of the staff, and greatly improving the lighting safety; and the three groups of LED lamp modules 81 are arranged linearly for illumination, so that the illumination area is wide, and the irradiated light overlaps and complements each other, so that the brightness of the entire lighting area is more uniform, thereby avoiding obvious brightness differences.

[0039] There is a height difference between the bottom of the inner concave foot 11 and the bottom of the main housing 1 of the floodlight, so that there is a gap between the main housing 1 of the floodlight and the ground of the helicopter airport, which makes use of the natural terrain so that when it rains, rainwater can smoothly flow through the gap to a lower place, effectively avoiding the problem of water accumulation caused by the obstruction of rainwater at the position of the floodlight;

[0040] Secondly, a convex ring 12 is arranged at the top of the main housing 1 of the floodlight to form a waterproof barrier. When rainwater penetrates into the interior from the gap of the upper cover 2, the convex ring 12 is higher than the top of the main housing 1 of the floodlight, so the infiltrated rainwater is blocked and difficult to enter the interior of the installation chamber, and the waterproof performance is high.

[0041] The floodlight is located between the lampshade glass 3 and the mounting groove 15, and a rubber waterproof ring 7 is installed to improve the sealing and prevent water from entering. In addition, there is a height difference between the bottom of the mounting groove 15 and the bottom of the lighting groove 16, which effectively blocks rainwater from entering the installation chamber, achieving double waterproofing. Finally, the focusing convex mirror 6 is inserted between a group of reinforcing rib structures 14, that is, between the two L-shaped ribs 141 and the right-angle rib combination, to block the lighting groove 16 channel, achieving triple waterproofing, and high waterproof performance;

[0042] In summary, floodlights have effectively solved the problem of outdoor lighting being easily eroded by rain through multiple waterproof designs. Their excellent waterproof performance not only protects the internal electronic components of the floodlights from damage, but also extends their service life and improves the lighting effect. At the same time, these designs also reduce maintenance costs and provide a more reliable and efficient lighting solution for the outdoor lighting field.
