Abstract
The invention is applicable to lighting for navigation and provides an airfield runway LED center line light. The LED center line light comprises LEDs, convergence lenses and prisms, wherein the convergence lenses are used for collimating the light emitted by the LEDs into parallel light; and the prisms are used for regulating the paths of the parallel light to ensure the parallel light to emit by dispersing upward in an oblique manner along the horizontal direction. After the LED center line light is connected with the power, the light emitted by the LEDs is changed into parallel light by the convergence lenses and enters into the prisms, the parallel light exits through refraction after being reflected by the prisms and disperses upward in an oblique manner along the horizontal direction during exiting, thus meeting the light distribution requirement of the airfield lights on the airfield taxiway bend. With the LEDs as the light sources, the LED center line light has low energy consumption, good shake resistance, long life and low maintenance cost.

Technical field
The invention belongs to the airfield aid field, relate in particular to the airfield runway center line lamp of a kind of LED of employing as light source.
Background technology
Existing airport embedded taxiway bend center line lamp uses the 48W halogen tungsten lamp as light source more, filters by the shades of colour optical filter again, and the power consumption height, the life-span is shorter, uses and the maintenance cost height.In addition, the halogen tungsten lamp volume is big, and its luminous intensity distribution mostly is the luminous intensity distribution of wide-angle cover type, has more illumination to be incident upon beyond the luminous intensity distribution zone, also may produce interference in the time of waste, the influence navigation.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of airfield runway LED center line light that satisfies airport taxiway bend light distribution requirements, is intended to solve existing line lamp power consumption height, problem that maintenance cost is also high.
The embodiment of the invention is achieved in that a kind of airfield runway LED center line light, comprising:
LED；
Plus lens is used for the optical alignment that described LED sends is become directional light;
Prism is used to adjust the light path of described directional light, makes it upwards to spread outgoing along horizontal tilt.
After homeplate runway LED center line lamp is connected power supply, the light that described LED sends becomes directional light by plus lens and is incident to prism, described directional light reflects outgoing by prismatic reflection, along upwards diffusion of horizontal tilt, satisfies the light distribution requirements of airport taxiway bend navaid light fixture during outgoing.Because adopt LED as light source, homeplate runway LED center line lamp energy consumption is low, resistance to shock is good, and the life-span is long, and maintenance cost is low.

The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The airfield runway LED center line light that the embodiment of the invention provides adopts LED as light source, this is done corresponding optical design, and (light distribution requirements: the optical axis of horizontal direction main beam to the angle on its both sides is that the horizontal direction angle is ± 20 ° to make its light distribution requirements that satisfies airport taxiway bend navaid light fixture; Vertical direction main beam to the angle of horizontal plane is that the vertical direction angle is 1～10 °).
A kind of airfield runway LED center line light comprises: LED; Plus lens is used for the optical alignment that described LED sends is become directional light; Prism is used to adjust the light path of described directional light, makes it upwards to spread outgoing along horizontal tilt.
Shown in Fig. 1～6, the airfield runway LED center line light that the embodiment of the invention provides has two opposing light directions, each light direction is provided with at least one LED as light source, number and the glow color of described LED are decided as requested, present embodiment adopts four high-power yellow light LEDs, and each light direction is provided with two yellow light LEDs 1.The lower casing 3 that described center line light fixture has a upper casing 2 and cooperates with described upper casing 2, described LED1 and plus lens are located in the described lower casing 3, and described prism 8 is arranged on the upper casing 2.Be provided with the plus lens that the optical alignment that described LED1 is sent becomes directional light in the described lower casing 3, described plus lens is corresponding one by one with LED.Described plus lens is the non-spherical lens 7 with a horizontal bottom 5 and an aspheric surface end face 6, and LED1 described in the present embodiment is positioned at the focus of described non-spherical lens 7.Be provided with a light path that is used to adjust described directional light along the transmission direction of described directional light, make it upwards to spread the prism 8 of outgoing along horizontal tilt.Described prism 8 has an incidence surface 9, a fully reflecting surface 10 and an exiting surface 11, and described incidence surface 9 is a horizontal bottom, and described fully reflecting surface 10 is the inclination indent face of cylinder, and described exiting surface 11 is the outer protruding cylinder surface that tilts; Described directional light through described fully reflecting surface scattered reflection, upwards reflects outgoing through described exiting surface along horizontal tilt through described incidence surface vertical incidence.The described prism 8 of present embodiment has two, and promptly each light direction is established a prism.The primary optical axis of non-spherical lens described in the present embodiment 7 is parallel to the normal of described incidence surface 9.
After homeplate runway LED center line lamp is connected power supply, the light that LED sends becomes directional light after by described non-spherical lens and is incident to prism 8, described directional light is tilted to diffusion by the reflection of fully reflecting surface 10 and the refraction of exiting surface 11 during outgoing, satisfy the light distribution requirements of airport taxiway bend.As shown in Figure 7, light intensity greater than the distribution of the light of 10cd is in the present embodiment: the horizontal direction angle is-25 °～25 °, and the vertical direction angle is-1～17 °; Light intensity greater than the distribution of the light of 50cd is: as the horizontal direction angle that Fig. 5 indicated is-22 °～22 °, is 0～11 ° as the vertical direction angle that Fig. 4 indicated; Hence one can see that, and homeplate runway LED center line lamp satisfies the light distribution requirements of airport taxiway bend fully.
In addition, the desired light distribution of the light of different colours is identical in the taxiway bend, and the luminous flux of the yellow light LED of equal-wattage and green light LED is different.In order to satisfy this requirement, the airfield runway LED center line light that another embodiment of the present invention provides has three LED, and one of them light direction is provided with two high-power yellow light LEDs, and another light direction is provided with a high-power green light LED; The airfield runway LED center line light that another embodiment of the present invention provides has two high-power green light LEDs, and each light direction is provided with a green light LED.The pilot makes corresponding operation in view of the above according to the light of different colours.
