Description

The airport LED lamp of two-way window independent operating

Technical field

The utility model is related to voyage aid of the airport LED lamp product, especially LED runway center line lights, LED runway edge lights, LED Taxiway center line light.

Background technology

Different types of LED lamp, different zones different windows lens emitting brightness are installed in airport different zones at present It is required that also different.In face of built-in bidirectional window LED lamp, control has two ways, and one kind is by two ground power units, two The corresponding separated independent control of individual isolating transformer, two LED lamps；Another is by two ground power units, two Individual isolating transformer, a LED lamp, but lamp interior installs two pieces of independent circuit boards, is two independences during LED operation Control loop.Above control mode, which is installed, to be needed to connect two isolating transformers, and each light fixture needs that a deep bucket is separately configured, Connection line is cumbersome, and this method of operation brings the unnecessary wasting of resources, can also increase cable and the increasing in airport light fixture loop The big space for taking isolating transformer case.Cause cost high using two pieces of circuit boards, and airport installation period and maintenance period It is elongated, while increasing airport construction cost.

Existing mounting means is primarily present following problem：

1. two-way window LED lamp, which is all a CPU, controls a light-emitting directions mouthful, control limitation is small, and LED lamp connects Line is more；2. a bidirectional LED lamp tool can only be controlled by a ground power unit；3. two-way window LED is caused using two pieces of circuit boards Cost is high, while maintenance cost also increases；4. two-way window LED lamp needs to increase isolating transformer number, circuit is installed numerous It is trivial, cause the wasting of resources；5. two-way window LED lamp needs to configure the isolating transformer vanning of greater room, bring unnecessary The wasting of resources；6. adding navigational lighting aid system circuit cable, power consumption is caused to increase.

The content of the invention

Technical problem to be solved in the utility model is：By the airport LED lamp one of two-way window independent operating Change design, the control circuit to two-way window LED is combined on one piece of circuit board, a ground power unit control single channel can be realized Output, a ground power unit control doubleway output, two ground power units that the various control pattern of doubleway output is separately controlled simultaneously.

The utility model, which solves the above problems, to be adopted the technical scheme that：Two-way window LED control circuit is combined in One piece of circuit board, is realized in two-way window LED lamp control, the independent operating of two-way window can pass through one or two airports Power supply and it does not interfere with each other.The board area of LED lamp is reduced, the miniaturization of circuit board greatlys save cost.

Concrete operation method is：The utility model enters the airport LED lamp internal circuit board of two-way window independent operating Row OVERALL OPTIMIZA-TION DESIGN FOR, isolating transformer plug receptacle 1, isolating transformer plug receptacle 2, transformer 1, transformer 2, lowering and stabilizing blood pressure electricity Road, CPU controls, LED drive circuit 1, LED drive circuit 2, LED/light source plug receptacle 1, a LED/light source plug receptacle 2 are combined in together One piece of circuit board.Different control models it can require to realize single, two ground power units to two-way window according to needed for airport The control of LED lamp.

The beneficial effects of the utility model are：

1. the utility model adds the control model to two-way window LED lamp；2. the utility model opening per paths of LEDs Road protection is separate, does not interfere with each other；3. the utility model reduces isolating transformer number, airport construction cost is reduced；4. Two-way control combines in one piece of circuit board, reduces board area, increase LED lamp mechanical structure inner space；5. isolate transformation The reduction of device number, effectively saves LED lamp return cable length, reduction system for aerial navigation on airport operation power consumption.

Brief description of the drawings

Fig. 1 is the airport LED lamp structure figure of the two-way window independent operating of the utility model.

Embodiment

Fig. 1 is referred to for the utility model structure chart, a kind of two-way window independent operating airport LED lamp is become by isolation Depressor plug receptacle 1, isolating transformer plug receptacle 2, transformer 1, transformer 2, decompression voltage regulator, CPU controls, a LED drive Dynamic circuit 1, LED drive circuit 2, LED/light source plug receptacle 1, LED/light source plug receptacle 2 are constituted, and combine in same circuit board.It is special Levy and be：When controlling two-way window LED lamp simultaneously using a ground power unit comprising two kinds of control models：One kind control mould Formula is that two isolating transformer plug receptacles on circuit board are connected, then accesses one loop of an isolating transformer composition；Separately A kind of control model is by correspondence two isolating transformers of access of transformer plug receptacle on circuit board 1,2.When using two airports When power supply controls two-way window LED lamp respectively, by isolating transformer plug receptacle on circuit board 1,2 respectively correspond to access one every From transformer.Because two-way LED controls are separate on circuit board, isolate transformation when accessing one using a ground power unit Device control single LED when, the LED/light source plug receptacle that LED/light source should be connected correctly, otherwise LED/light source do not work.When two-way window LED lamp is when a paths of LEDs breaks down in the process of running, corresponding open circuit self-shield module will automatic start protection, Will not start from open-circuit-protection all the way in addition.
