The LED taxiway centerline light is characterized in that a light beam shaping chamber is additionally provided behind each prism, a green light LED light source set is provided behind each light beam shaping chamber, each green light LED light source set comprises a green light LED array and a reflection cup welded on an aluminum substrate, the green light LED array is fixedly arranged in the reflection cup, and the reflection cup is fixedly connected with the light cover. According to the utility model, the problem that the prior taxiway centerline light is easy to damage for a large radial dimension is solved.
Description
Technical field
The utility model relates to a kind of LED taxiway center line light, and it belongs to airport navaid lighting class.
Background technology
Airport navaid lighting has plurality of specifications according to the purposes difference, and taxiway center line light is wherein a kind of, and existing taxiway center line light is that CN200820154665.8 is disclosed; The disclosed this taxiway center line light of CN200820154665.8 comprises light cover, bowl-type bromine tungsten bubble, inner cover, base, and said light cover is provided with two opposing shrinkage pools; The axis of each shrinkage pool and the axis of light cover have angle; Respectively be provided with a prism apparatus along its axis in each shrinkage pool, said prism apparatus back respectively is provided with a bowl-type bromine tungsten bubble, before the bowl-type bromine tungsten bubble filter is housed; The light cover below is connected with base through bolt, constitutes whole.The problem that prior art exists is that the radial dimension of taxiway center line light is bigger, causes a main cause of this situation to be that the big bowl-type bromine tungsten bubble of length dimension is arranged on the rear of prism apparatus.On the other hand; Originally just often fracture under the effect of tungsten filament powerful vibration force in aircraft landing and take-off process of bromine tungsten bubble, the life-span is shorter, and the volume of taxiway center line light is bigger; The vibration that it absorbed is also bigger; The vibration that this has just more aggravated tungsten filament makes failure-frequency higher, and obviously prior art has further improved necessity.
Summary of the invention
The purpose of the utility model is to provide a kind of LED taxiway center line light, to overcome the problem that prior art exists.
A kind of LED taxiway center line light of the utility model; Comprise light cover, light source body, base, power input line; Said light cover and base be through connector and silica gel sealing pad sealed attachment, and said light cover is provided with the spill window of two opposing and certain positions that stagger each other, and the projection of the projection of the axis of each spill window and the axis of light cover has angle; Respectively be provided with a prism apparatus in each spill window along its axis; Said prism apparatus connects firmly through plastic structural part and stainless steel platen and light cover and connects, and it is characterized in that having set up the beam shaping chamber after the said prism apparatus, is provided with the green light LED light sources after the said beam shaping chamber; Said green light LED light sources comprises green light LED array and the reflector that is welded on the aluminium base; Said green light LED array is arranged in and is fixedly arranged on said reflector, and said reflector and light cover connect firmly and connect, and are provided with driving power in the said base.
This LED taxiway center line light of the utility model; Because with adopting the green light LED array to substitute bromine tungsten bubble of the prior art; Its length dimension greatly reduces, the situation the when structural volume of the utility model is much smaller than light source body employing bromine tungsten bubble for this reason, thus the radial dimension of a kind of LED taxiway center line light of the utility model will be much smaller than prior art; Like this; Its vibration of experiencing at work is much little than prior art, moreover the bromine tungsten of the relative prior art of antivibration ability of green light LED array bubble is far better, and obviously the purpose of the utility model is achieved.
As further improvement, said reflector is compounded to form by curved reflecting surface and flat shield, can make the light beam of launching through the spill window meet the requirement of lead-in-light system standard more like this.
