Abstract
The utility model discloses an LED center line lamp used on an airport exit running lane. The LED center line lamp used on the airport exit running lane comprises a surface cover and a bottom cover which are fixedly connected, wherein two light outgoing ports arranged in a bidirectional symmetry mode and corresponding drainage grooves are formed in the surface cover, a prism and a light diffusing piece are embedded in each light outgoing port from outside to inside in sequence, a reflection cup corresponding to each light outgoing port and an aluminum substrate corresponding to each light outgoing port are arranged on the bottom of the surface cover, LEDs are welded on the aluminum substrates, light emitted by the LEDs is focused through the reflection cups and then shoots towards the light diffusing pieces in parallel, and the LEDs are connected with a lamp controller arranged in the bottom cover through wires. The LED center line lamp used on the airport exit running lane has the advantages that the secondary optical design of the LEDs is achieved by the combination of the reflection cups and the prisms, and therefore requirements of the navigation aiding lamp for the angle and intensity of light distribution are met; due to the fact that the LEDs are adopted as the light source, the service life is long, energy consumption is low, luminous efficiency is high, and the structure is simple. The LED center line lamp used on the airport exit running lane can emit green light and yellow light and is especially suitable for being used on the airport exit running lane.
Description
Technical field
The utility model relates to voyage aid of the airport light fixture technical field, particularly a kind of airport LED exit taxiway middle-line lamp.
Background technology
At present, traditional airport exit taxiway middle-line lamp is take halogen tungsten lamp as light source.Halogen tungsten lamp relies on filter and lens that light color and angle are controlled, thereby satisfies the international standard of navigational lighting aid system.
Yet traditional airport exit taxiway middle-line lamp exists the shortcomings such as service life is short, light efficiency is low, the power consumption is high, complex structure, maintenance cost height owing to adopting halogen tungsten lamp as light source.Along with the development of science and technology, LED is applied to the navigational lighting aid field becomes possibility gradually.LED has advantages of that the life-span is long, light efficiency is high, power consumption is low, simple in structure, maintenance cost is low, and the navaid light fixture adopts LED will become gradually development trend as light source.
But the characteristics of luminescence of LED and traditional halogen tungsten lamp are essentially different, and for the international standard that satisfies the navigational lighting aid system, the technical approach of its realization also is very different.Therefore airport LED exit taxiway middle-line lamp with respect to traditional exit taxiway middle-line lamp, must carry out secondary optical design, heat dissipation design, structural design and control circuit design.
The utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of LED middle-line lamp that is exclusively used in the airport exit taxiway.
The technical solution adopted in the utility model is such: a kind of airport LED exit taxiway middle-line lamp, comprise the cover and the bottom that are fixed together, light-emitting window and corresponding drain groove that two bi-directional symmetrical are arranged on described cover, embed successively from outside to inside prism and scattering sheet in each light-emitting window, the aluminium base that corresponding each light-emitting window in cover bottom arranges a reflector and is welded with LED, normal sheaf scattering sheet after the light that reflector sends LED focuses on, the described LED lamp controller wire interior with being arranged on bottom is connected.
As preferably, each light-emitting window LED of two series connection on corresponding aluminium base respectively on described cover.
Further preferred as to above-mentioned optimal way, the two LEDs green light that a described light-emitting window is corresponding, the two LEDs Yellow light-emitting low temperatures that another light-emitting window is corresponding.
Described lamp controller is by the cable external power supply.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: the secondary optical design of LED adopts reflector and the combined mode of prism, can satisfy the navaid light fixture to the angle of light distribution and the demand of intensity; Use LED as light source, the life-span is long, and energy consumption is low, and light efficiency is high, and is simple in structure; Can send two kinds of light of green glow and gold-tinted; Be particularly suitable for the airport exit taxiway.
Description of drawings
Fig. 1 is principle schematic of the present utility model.
Mark in figure: 1 is cover, and 2 is prism, and 3 is scattering sheet, and 4 is LED, and 5 is aluminium base, and 6 is reflector, and 7 is lamp controller, and 8 is bottom, and 9 is cable.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment: as shown in Figure 1, a kind of airport LED exit taxiway middle-line lamp, comprise the cover 1 and the bottom 8 that are fixed together, light-emitting window and corresponding drain groove that two bi-directional symmetrical are arranged on described cover 1, embed successively from outside to inside prism 2 and scattering sheet 3 in each light-emitting window, the aluminium base 5 that corresponding each light-emitting window in cover 1 bottom arranges a reflector 6 and is welded with LED 4, normal sheaf scattering sheet 3 after the light that reflector 6 sends LED4 focuses on, described LED 4 lamp controller 7 wires interior with being arranged on bottom 8 are connected.
The LED 4 of two series connection on the corresponding aluminium base 5 of each light-emitting window difference on described cover 1.
Two LEDs 4 green light that a described light-emitting window is corresponding, two LEDs 4 Yellow light-emitting low temperatures that another light-emitting window is corresponding.
Described lamp controller 7 is by cable 9 external power supplys.
Prism 2, scattering sheet 3, reflector 6 and the common core optical component that forms in the utility model of aluminium base 5 that is welded with LED 4, the light that LED 4 sends is assembled by reflector 6, parallel inciding on scattering sheet 3, realize through scattering sheet 3 injecting prism 2 after the diffusion of light angle, completed the adjustment of beam projecting angle by prism 2, finally reach civil aviaton's standard to the rising angle of navaid light fixture and the requirement of luminous intensity.
