Abstract

The utility model discloses an airport LED earth strip lamp which comprises a face cover and a bottom cover which are connected together. A light outgoing opening and a corresponding water drainage groove are formed in the face cover, a prism is embedded in the light outgoing opening, a radiator with an upward inner-concave face is fixed at the bottom of the face cover, an LED aluminum substrate is fixedly welded in the concave face of the radiator, a lens covers an LED, light sent by the LED is collimated through the lens, the light is incident into the prism in parallel to complete adjustment on light outgoing opening angles, a lamp controller is arranged in the bottom cover, and the lamp controller is connected with the LED through a lead. The airport LED earth strip lamp has the advantages of adopting the LED as a light source, being long in service life, low in energy consumption and high in light efficiency, being good in heat radiation performance due to the fact that the radiator is combined with the face cover, and meeting the requirement for light distribution of the airport earth strip due to the fact that the prism is combined with the lens.

Description

A kind of airport LED touchdown zone light

Technical field

The utility model relates to voyage aid of the airport light fixture technical field, particularly a kind of airport LED touchdown zone light.

Background technology

At present, traditional touchdown zone light is take halogen tungsten lamp as light source.Halogen tungsten lamp relies on optical filter and lens that light color and angle are controlled, thereby satisfies the international standard of navigational lighting aid system.

Yet traditional touchdown zone light 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.Because LED has the advantages such as the life-span is long, light efficiency is high, power consumption is low, simple in structure, maintenance cost is low, the navaid technical field of lamps adopts LED will become development trend as light source.

But the characteristics of luminescence of LED and traditional halogen tungsten lamp are essentially different, and satisfy the international standard of navigational lighting aid system, and the technical approach of its realization also is very different.Therefore the LED touchdown zone light with respect to traditional touchdown zone light, 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 airport LED touchdown zone light.

the technical solution adopted in the utility model is such: a kind of airport LED touchdown zone light, comprise the cover and the bottom that link together, a light-emitting window and corresponding drain groove are set on described cover, embed prism in light-emitting window, the cover bottom is the supine radiator of indent fixedly, be fixedly installed the aluminium base that is welded with LED in the radiator concave surface, described LED is housed in below lens, the rays pass through lens that LED sends collimates, parallelly incide the adjustment that prism is completed the beam projecting angle, in described bottom, lamp controller is set, this lamp controller is connected with the LED wire.

As preferably, described LED has four, and series connection, all emit white light successively.

As preferably, 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: adopt four LED lamps that emit white light, unidirectional emission goes out light, is particularly suitable for the occasion of airfield runway counterpoise grounding; Adopted LED as light source, the life-span is long, and energy consumption is low, and light efficiency is high; Radiator and cover form complete heat radiation system, perfect heat-dissipating; The optics combination of prism and lens has satisfied the light distribution requirement to the airport counterpoise grounding.

Description of drawings

Fig. 1 is theory structure schematic diagram of the present utility model.

Mark in figure: 1 is cover, and 2 is prism, and 3 is lens, and 4 is LED, and 5 is aluminium base, and 6 is radiator, 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.

most preferred embodiment: as shown in Figure 1, a kind of airport LED touchdown zone light, comprise the cover 1 and the bottom 8 that link together, a light-emitting window and corresponding drain groove are set on described cover 1, embed prism 2 in light-emitting window, cover 1 bottom is the supine radiator 6 of indent fixedly, be fixedly installed the aluminium base 5 that is welded with LED4 in radiator 6 concave surfaces, described LED4 is housed in below lens 3, the rays pass through lens 3 that LED4 sends collimates, parallelly incide the adjustment that prism 2 is completed the beam projecting angle, the interior lamp controller 7 that arranges of described bottom 8, this lamp controller 7 is connected with LED4 by wire and by cable 9 external power supplys.

Described LED4 has four, and series connection, all emit white light successively.In the present embodiment, adopted four LEDs, power ratio is larger, so radiator is in demand, not so, the time has been grown and can cause the internal temperature of lamp too high, the impact normal operation.

The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
