Description

Technical Field

[0001] The invention belongs to the technical field of taxiway centerline lights, and in particular relates to a taxiway centerline light compatible with ordinary light intensity and high light intensity. Background Art

[0002] Taxiway centerline lights are used in the field of airport navigation lights. In terms of navigation aids, taxiway centerline lights are divided into ordinary light-intensity taxiway centerline lights for general application environments, and high-intensity taxiway centerline lights used in advanced ground movement guidance and control systems. The intensity requirements for ordinary light-intensity taxiway centerline lights are relatively low, while the intensity requirements for high-intensity taxiway centerline lights are higher.

[0003] Normal intensity taxiway centreline lights shall be installed on exit taxiways, de-icing and anti-icing facilities and aprons used when the runway visual range is less than 350m, taxiways used at night when the runway visual range is greater than or equal to 350m, complex taxiway intersections and exit taxiways, and runways that are part of standard taxi routes, regardless of visibility. High intensity taxiway centreline lights shall be installed on exit taxiways, de-icing and anti-icing facilities and aprons that are part of advanced surface movement guidance and control systems.

[0004] At present, the taxiway centerline lights used in domestic airports are all ordinary light intensity taxiway centerline lights, with an average main beam intensity of 100-600cd, which cannot be used for advanced ground activity guidance; the high-intensity taxiway centerline lights have an average main beam intensity of up to 1800cd, which can easily interfere with the pilot's vision at night and cannot be used for night operations under normal visibility at the airport. At present, there is no research and application of high-intensity taxiway centerline lights in China.

[0005] As the Civil Aviation Administration vigorously promotes the application of the Advanced Surface Movement Guidance and Control (A-SMGCS) system at airports, there are many overlaps in the application scenarios of ordinary light intensity and high light intensity taxiway centerline lights. If the two are not compatible, the same scene will be equipped with both ordinary light intensity and high light intensity taxiway centerline lights, which will greatly increase the cost of airport construction, maintenance, equipment procurement, etc. Summary of the invention

[0037] Embodiment 1:

[0038] The present invention provides a taxiway centerline light compatible with ordinary light intensity and high light intensity, such as Figure 1 and Figure 2 As shown, it comprises a lamp cover 1 and an inner cover 12, wherein a receiving cavity is formed between the lamp cover 1 and the inner cover 12, and a controller 11 is arranged in the receiving cavity;

[0039] The lamp cover 1 is provided with an optical path channel 15, the central axis of the optical path channel 15 forms an angle with the central axis of the lamp cover 1, and the optical path channel 15 is provided with a light source 7, a lens 6 and a prism assembly from the inside to the outside, and the prism assembly includes a prism 3; the light emitted by the light source 7 enters the prism 3 after being collimated by the lens 6, and the light is refracted out from the light outlet after being reflected or transmitted by the prism 3;

[0040] The light source 7 includes a common light source 7 and a high light source 7, both of which are LED light sources; the controller 11 is electrically connected to the common light source 7 and the high light source 7, respectively, and the controller 11 communicates with an external terminal. The controller 11 obtains a current dimming instruction from the external terminal; and controls the common light source 7 or the high light source 7 to work according to the current dimming instruction.

[0041] The taxiway centerline light of this embodiment includes two light sources 7, one for normal light intensity lighting, and its main beam average light intensity is 100-600cd; the other for high light intensity lighting, and its main beam average light intensity is up to 1800cd; the controller 11 controls one of the light sources 7 to work according to the external dimming instruction. This embodiment can send the dimming instruction to the controller 11 in two ways. One way: the external terminal uses an infrared remote controller, and the controller 11 obtains the current dimming instruction by infrared communication; the other way: the external terminal uses an intelligent terminal, and the controller 11 obtains the current dimming instruction by wireless, power line carrier, optical fiber and other communication methods.

[0042] When the controller 11 receives the normal dimming instruction from the terminal, the normal light source 7 is controlled to work; when the controller 11 receives the high light dimming instruction from the terminal, the high light source 7 is controlled to work. When the normal light source 7 is working, the normal light enters the prism 3 after being collimated by the lens 6, and the normal light is refracted out from the light outlet of the lamp cover 1 after being reflected or transmitted by the prism 3; when the high light source 7 is working, the high light enters the prism 3 after being collimated by the lens 6, and the high light is refracted out from the light outlet of the lamp cover 1 after being reflected or transmitted by the prism 3.

The accommodating cavity and the optical path channel 15 of this embodiment are connected, and the support member 9 is located between the accommodating cavity and the optical path channel 15. The support member 9 is fixed to the lamp cover 1 by stainless steel screws. The aluminum substrate 8 has a structure of simultaneous heat dissipation on the front and back sides, thereby improving the heat dissipation effect.

The inner cover 12 is provided with an outlet for the cable to pass through. When the plug 10 is plugged into an external power supply device, it provides working power for the controller 11. The taxiway centerline lamp of this embodiment has lamp components combined in groups, which can not only make the most of the narrow internal space of the lamp, but also facilitate maintenance and replacement of components.

[0048] The lamp cover 1 of this embodiment has a diameter of 8 inches and is made of a special aluminum alloy material. By using a high-strength aluminum alloy, the gap between the lamp cover 1 and the light outlet of the prism 3 is controlled while meeting the structural strength of the lamp. In this embodiment, the height difference between the upper edge and the lower edge of the light outlet of the lamp cover 1 is less than or equal to 6.3m, that is, the height of the upper edge of the light outlet of the prism 3 above the horizontal reference plane, meeting the standard requirement that the height of the top surface of the lamp above the horizontal reference plane should be no more than 6.3mm.

[0049] In summary, the taxiway centerline light of this embodiment has the functions of both ordinary light intensity and high light intensity taxiway centerline lights.
