Description

Technical Field

[0001] This utility model belongs to the field of airport runway lighting technology, specifically relating to a high-position light assembly for airport runway inspection vehicles. Background Technology

[0002] Aircraft travel at high speeds during takeoff and landing at airports. Even small foreign objects on the runway, such as stones, metal fragments, or plastic bags, can cause serious damage to critical components like landing gear and tires, and may even lead to serious accidents like tire blowouts. Furthermore, frequent takeoffs and landings cause wear and tear on the runway, and environmental factors can also cause unevenness or cracks in the runway surface. Inspections can identify these problems, remove these intrusive foreign objects, and promptly arrange runway maintenance to ensure the runway maintains good flatness and meets the safety requirements for aircraft takeoff and landing.

[0003] When conducting airport runway inspections at night, it is necessary to use lighting for the inspection. However, the lighting design of existing inspection vehicles is unreasonable and cannot better assist inspectors in clearly observing the runway surface and the surrounding environment, which may lead to the overlooking of potential dangers and obstacles. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-position lighting assembly for airport runway patrol vehicles, addressing the unreasonable design of lighting lights on existing patrol vehicles.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A high-mounted light assembly for an airport runway inspection vehicle includes a mounting plate and two LED floodlights; the LED floodlights are fixedly mounted on the mounting plate on the top of the airport runway inspection vehicle.

[0007] The angle between the light-emitting surfaces of the two LED floodlights is 185-200 degrees; the angle between the light-emitting surface of the LED floodlight and the ground is 83-87 degrees.

[0008] Furthermore, the LED floodlight contains LED light-emitting chips arranged in a matrix; each row or column of LED light-emitting chips is connected in parallel to form an LED light group, and multiple LED light groups are connected in parallel.

[0009] Furthermore, each LED group of one of the LED floodlights is connected in parallel one-to-one with each LED group of the other LED floodlight, and each group is connected in series with an independent control switch after being connected in parallel.

[0010] Preferably, the beam angle of the floodlight is between 30 and 60 degrees.

[0011] Preferably, the floodlight has a dustproof and waterproof rating of IP66 or higher.

[0012] Compared with existing technologies, this utility model utilizes two medium-beam LED floodlights as high-level lighting units on an airport runway inspection vehicle. The reasonable angle installation and circuit connection design allow the lighting beams to complement each other, expanding the lighting range, reducing shadow areas, and achieving illumination of the airport runway inspection area. Multiple brightness lighting modes adapt to different scene requirements, improving the observation effect of the inspection vehicle driver and observer on the runway condition.

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] See Figure 1A high-mounted lighting assembly for an airport runway inspection vehicle includes a mounting plate and two LED floodlights (LED floodlight A and LED floodlight B). The LED floodlights are fixedly mounted on the mounting plate 1 on the top of the airport runway inspection vehicle. When the light from LED floodlights A and B is reflected by reflectors 2 onto the light-emitting surfaces, the angle θ1 between the two light-emitting surfaces is 185-200 degrees; the angle θ2 between the light-emitting surfaces of the LED floodlights and the ground is 83-87 degrees. The relative angle between the two light-emitting surfaces ensures that the illumination range covers a large area around the inspection vehicle, including the area in front of and diagonally in front of the runway. This helps the driver clearly observe the runway and its surroundings during inspections, reducing blind spots.

[0021] The angle between the light-emitting surface and the ground can create a high light intensity on the runway surface. At the same time, due to the oblique incidence of the light, obvious light and dark contrast will be produced on the protrusions and depressions of the runway surface, making it easier for drivers and observers to detect unevenness or foreign objects on the runway surface, thereby improving the accuracy and reliability of the track inspection work.

[0022] When the runway inspection vehicle is in motion, the driver's line of sight is typically tilted towards the road surface. An angle of 83-87 degrees between the light-emitting surface and the ground ensures that the beam of the floodlight is relatively aligned with the driver's line of sight, reducing visual fatigue and glare caused by unsuitable lighting angles when observing the runway. This design also concentrates the light primarily on the runway and its surrounding area, reducing light scattering and spillage into the surrounding environment, and minimizing light pollution interference to airport facilities, staff, and aircraft takeoffs and landings. An appropriate angle between the light-emitting surface and the ground ensures that the floodlight beam does not shine directly into the sky or enter the pilot's line of sight, avoiding interference with the pilot's vision and thus reducing safety hazards associated with aircraft takeoffs and landings.

[0023] Furthermore, the LED floodlight contains a matrix of LED light-emitting chips 3; each row or column of these chips is connected in parallel to form an LED light group 31, and multiple LED light groups 31 are connected in parallel. If one of the LED light groups 31 malfunctions, such as due to damaged LED chips or a wiring problem, the other parallel LED light groups or LED chips will still function normally, preventing the entire floodlight or both floodlights from failing completely. This ensures that the lighting system provides sufficient light during airport runway inspections, guaranteeing the continuity and safety of the work.

[0024] Furthermore, each LED group 31 of one of the LED floodlights is connected in parallel one-to-one with each LED group 31 of the other LED floodlight, and each group is connected in series with an independent control switch. In adverse weather conditions such as rain or snow at night, or under varying moonlight conditions, the independent switch control allows for precise control of the LED floodlight brightness. In airport runway inspection vehicle applications, this reduces road surface reflection interference. Rainy days cause water accumulation on the runway surface to reflect light; adjusting the overall illuminance of the floodlights using independent control switches in groups reduces this reflection effect, lowering the brightness to avoid glare for the driver's eyes and allowing the driver to see the true runway conditions more clearly.

[0025] Preferably, the floodlight is a medium-beam angle floodlight with a beam angle between 30 and 60 degrees. The floodlight has a dustproof and waterproof rating of IP66 or higher. Medium-beam LED floodlights have high light intensity output, providing brighter light and helping drivers see various details on the track more clearly, such as surface damage, foreign objects, and markings. This is especially important at night or in low visibility conditions, such as fog, haze, rain, or snow, when there are many suspended particles in the air, causing light to be easily scattered and absorbed, resulting in poor lighting performance. Medium-beam LED floodlights emit relatively concentrated light with strong penetration and good range illumination, better assisting in track inspection work.

[0026] Each LED group 31 of the LED floodlight is connected in parallel one-to-one with each LED group 31 of another mirror-symmetrical LED floodlight, and each group is connected in series with an independent control switch. The symmetrical parallel arrangement of the LED groups 31 makes the light intensity within the light-emitting range of this high-position light group more uniform.

[0027] In some possible embodiments, the parallel LED light groups 31 of the two floodlights are controlled by independent control switches to gradually light up from the inside out.

[0028] In some possible embodiments, the parallel LED light groups 31 of the two floodlights are controlled by independent control switches to gradually light up from the outside to the inside.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
