Description

Technical Field

[0001] This utility model relates to the field of control circuit technology, and in particular to a split-type control circuit for aviation obstruction lights. Background Technology

[0002] In the civil aviation sector, aviation obstruction lights are an important facility for ensuring aviation safety, and their performance directly affects the flight safety of aircraft and the orderly operation of the aviation sector.

[0003] Currently, aviation obstruction lights on the market generally suffer from several insurmountable problems. In terms of power, traditional aviation lights have relatively low power, generally not exceeding 50W, which limits their application in some large buildings or long-distance warning scenarios, making it difficult to provide sufficient warning effects. Regarding strobe control, their flashing frequency is fixed and cannot be flexibly adjusted according to actual needs, and the synchronized flashing function is highly susceptible to weather conditions. For example, in severe weather such as heavy rain or sandstorms, the synchronization between multiple aviation lights is disrupted, leading to chaotic warning signals and significantly reducing the reliability of the aviation obstruction light system.

[0004] Furthermore, traditional aviation lights are mostly integrated designs, with the luminaire and control unit combined. This severely limits the range of luminaire options, and the control circuit cannot be tailored to the actual power of the luminaire. This design not only affects product performance but also increases maintenance costs; if a component fails, the entire luminaire often needs to be replaced.

[0005] Furthermore, traditional aviation lights have strict requirements on installation angle and inter-lamp distance during installation and commissioning, increasing the difficulty and complexity of installation and resulting in higher installation and commissioning costs. Moreover, the control circuit wiring of traditional aviation lights is complex, with lower safety and reliability, making them prone to safety accidents due to circuit faults.

[0006] With the rapid development of the aviation industry, the performance requirements for aviation obstruction lights are becoming increasingly stringent. To address the aforementioned problems of traditional aviation lights and meet market demands for high-performance, high-reliability aviation obstruction lights, this invention proposes a split-type control circuit for aviation obstruction lights. This invention divides the aviation obstruction light into a lighting component and a control component. Through a flexible split design, it separates the lighting component selection from the control circuit, effectively overcoming the limitations of traditional aviation lights in terms of power, flicker control, installation, and debugging. This significantly improves the performance and reliability of aviation obstruction lights, demonstrating remarkable innovation and practicality. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a split-type control circuit for aviation obstruction lights, which solves the technical problems of low power, flickering affected by the environment, limited selection of lamps, and complex installation and debugging of traditional aviation obstruction lights.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A split-type control circuit for aviation obstruction lights, wherein the control loop can select parameters according to the power of the lights, the control circuit comprising:

[0010] AC power supply: It includes L and N terminals that provide 220V AC power;

[0011] Lighting power switch QF1 and control power switch QF2: QF1 is used to control the lighting power supply, and QF2 is used to control the control power supply.

[0012] Cyclic time relay KA: When QF2 is closed, it is powered by DC power supply AC220 / 24V. KA controls the energization and de-energization of the coils of solid-state contactors KM1 and KM2 according to different models and functions of the control mode.

[0013] Solid-state contactors KM1 and KM2: Their normally open contacts are controlled by the KM coil and are used to control the light source to flash.

[0014] Preferred: The aviation obstruction light controlled by the aviation obstruction light control circuit uses ordinary LED lamps as the light source. When selecting lamps, select lamp beads and covers that are suitable for the required light color, and the selection of lamps is not affected by the control circuit.

[0015] Preferred option: The cyclic time relay KA is used as a strobe controller. The control is not affected by the environment, and it can ensure that multiple aviation lights strobe synchronously. Different types or models of components can be selected as needed to achieve different strobe requirements.

[0016] Preferably, the strobe of the aviation obstruction light control circuit is controlled by a solid-state contactor. Compared with an integrated aviation light, it is not limited by the aviation light housing and power. The type and size of the solid-state contactor can be selected according to the parameters of the light fixture to configure the control circuit.

[0017] Preferably, the aviation obstruction light control circuit is separate from the strobe circuit, and the control circuit uses DC 24V voltage control, which simplifies the wiring of the control circuit and improves reliability and safety.

[0018] Preferably, the control circuit can realize multi-loop time-sharing control to improve reliability.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] I. The split-type control design significantly enhances the flexibility and applicability of aviation obstruction lights. By separating the lights from the control circuit, light selection is no longer limited by the control circuit; LED lights of different power and colors can be selected according to actual needs, breaking through the traditional aviation light power limit of no more than 50W. The control section uses cyclic time relays and solid-state contactors, achieving stable synchronous flashing unaffected by the environment. Furthermore, the flashing frequency can be flexibly adjusted by replacing components, solving the problems of fixed flashing and susceptibility to weather interference in traditional equipment. Simultaneously, the control circuit uses a safe 24V DC voltage, making wiring simple and reliable. Installation is not limited by angle or light spacing, greatly reducing debugging difficulty and maintenance costs.

[0021] Second, the multi-loop time-sharing control design effectively improves system redundancy, ensuring normal operation of other loops even in the event of a single loop failure. This makes it suitable for scenarios with extremely high safety requirements, such as airports and high towers. Solid-state contactors are flexibly configured according to the lamp parameters, avoiding the limitations imposed on control performance by the housing and power in integrated designs, enabling stable operation of aviation lights in complex environments. This design retains the advantages of traditional lamp light sources while achieving an upgrade from "fixed function" to "flexible adaptation" through innovative control circuitry, providing strong support for the reliability and safety of aviation obstruction light systems.

[0022] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] Figure 1 This is a circuit diagram of the present invention. Detailed Implementation

[0024] This application provides a split-type control circuit for aviation obstruction lights, which effectively solves the technical problems of traditional aviation obstruction lights, such as low power, flickering affected by the environment, limited selection of lamps, and complex installation and debugging.

[0025] Example

[0026] like Figure 1 As shown, the overall technical solution in this application embodiment is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a split-type control circuit for aviation obstruction lights. The aviation obstruction light consists of a lighting component and a control circuit component. The circuit composition and connection are as follows:

[0028] Power Supply: This control circuit is powered by an AC power supply, with 220V AC power introduced through the L and N terminals. QF1 is the lighting power switch, controlling the power supply to the lighting fixture; QF2 is the control power switch, controlling the power supply to the control unit. When the aviation obstruction lights need to be activated, QF1 and QF2 are closed respectively to supply power to the lighting fixture and control circuit.

[0029] Control core components:

[0030] DC power supply AC220 / 24V: When QF2 is closed, the DC power supply starts to work, converting 220V AC power to 24V DC power to power the cyclic time relay KA.

[0031] Cyclic time relay KA: As the core component of strobe control, it offers multiple control modes depending on its model and function. In practical applications, a suitable cyclic time relay model can be selected based on specific strobe requirements. It can control the energization and de-energization of the coils of solid-state contactors KM1 and KM2.

[0032] Strobe control section: The coils of solid-state contactors KM1 and KM2 are controlled by the cyclic time relay KA. When KA controls the coils of KM1 and KM2 to be energized, their normally open contacts close, and the light source is energized and emits light; when KA controls the coils to be de-energized, the normally open contacts open, and the light source goes out, thus achieving the strobe effect of the light source.

[0033] Lighting Selection: Aviation obstruction lights use standard LED lights as the light source. When selecting lights, suitable LED chips and housings with appropriate light colors can be chosen based on actual needs. Furthermore, due to the modular design, light selection is not affected by the control circuit, allowing users to flexibly choose appropriate lights according to different application scenarios and requirements.

[0034] Strobe Controller Selection: The KA cyclic time relay, as a strobe controller, has the advantage of being unaffected by environmental conditions and can ensure synchronized strobe flashing of multiple aviation lights. Functionally, different types or models of cyclic time relays can be selected according to specific strobe requirements to achieve different strobe effects.

[0035] Solid-state contactor selection: The strobe function of the luminaire is controlled by a solid-state contactor. Unlike integrated aviation lights, this control circuit is not limited by the aviation light housing or power. In practical applications, a suitable type and size of solid-state contactor can be selected based on the specific parameters of the luminaire, such as power and voltage, to configure a reasonable control circuit.

[0036] Installation and Commissioning: Aviation obstruction lights offer great flexibility in installation, unrestricted by installation angle or spacing between lights. During installation, simply connect all components correctly according to the circuit connection requirements. Furthermore, because the control circuit and strobe circuit are separate, and the control circuit uses DC 24V voltage control, wiring is simple, making installation and commissioning more convenient and improving the reliability and safety of the control circuit.

[0037] Multi-loop time-sharing control:

[0038] This control circuit features multi-loop time-sharing control. By appropriately setting the control mode and parameters of the cyclic time relay KA, different loops of aviation obstruction lights can be made to flash at different times, thereby improving the reliability and stability of the entire aviation obstruction light system. For example, in large buildings or complex aviation areas, multiple aviation obstruction lights can be divided into different loops and controlled in a time-sharing manner to ensure effective warning under any circumstances.

[0039] Working principle:

[0040] The power supply for this control circuit is a 220V AC power source introduced through the L and N terminals. QF1 is the lighting power switch, and QF2 is the control power switch. When the aviation obstruction light system needs to be activated, QF2 is closed, supplying power to the control system. At this time, the AC220 / 24V DC power supply begins operating, converting the 220V AC power to 24V DC power to supply power to the cyclic time relay KA, enabling it to start operating. Simultaneously, QF1 is closed, providing power to the lighting fixtures.

[0041] The cyclic time relay KA is a key component for realizing the strobe function of aviation obstruction lights. It offers various models and control modes with different functions, allowing users to select according to their needs. When KA is energized, it controls the energization and de-energization of the coils of solid-state contactors KM1 and KM2 according to a pre-set control mode. For example, if set to a specific time interval cyclic mode, KA will energize the coils of KM1 and KM2 for a period of time within one cycle, and then de-energize them for a period of time, repeating this cycle continuously.

[0042] The normally open contacts of solid-state contactors KM1 and KM2 are controlled by the state of their coils. When KA controls the coils of KM1 and KM2 to be energized, the normally open contacts close, connecting the light source to the power supply and causing it to emit light. When KA controls the coils to be de-energized, the normally open contacts open, disconnecting the light source from the power supply and turning off the light. This method achieves the flickering effect of the light source.

[0043] Traditional aviation light strobe synchronization is easily affected by weather conditions, while this invention uses a cyclic time relay KA as the strobe controller. Since KA operates based on its own electronic control logic, it is unaffected by external environmental factors such as humidity and temperature, thus ensuring stable synchronous strobe synchronization for multiple aviation lights. Traditional aviation lights generally have low power and are limited by their housing; the strobe of this invention is controlled by a solid-state contactor. The selection of the solid-state contactor can be based on the specific parameters of the light fixture, without being constrained by the aviation light housing or power. This allows users to choose lights with higher power and better performance, expanding the application range of aviation obstruction lights.

[0044] This control circuit features multi-loop time-sharing control. By precisely setting the cyclic time relay KA, solid-state contactors in different loops can operate at different times. The control loop is separate from the strobe loop, and the control loop uses DC 24V voltage control, simplifying wiring and enhancing system safety and stability.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
