Description

Technical Field

[0001] This invention belongs to the field of navigation light enhancement and adjustment, specifically relating to a navigation light enhancement and adjustment system based on Bluetooth communication. Background Technology

[0002] In the air transport system, navigation lights, as critical visual guidance devices, are widely used in airport runways, taxiways, aprons, and on the aircraft themselves. Their light intensity stability directly affects flight safety. Whether it's nighttime takeoffs and landings, flight operations in low-visibility weather conditions, or en-route signage, navigation lights must be maintained within the light intensity range that meets aviation safety standards. If the light intensity is too weak, pilots may be unable to accurately identify runway boundaries or obstacles; if the light intensity is too strong, it may cause glare interference, increasing the risk of visual fatigue and operational errors.

[0003] However, during long-term use, navigation lights are affected by factors such as light source aging (e.g., LED light decay and incandescent tungsten filament loss), circuit component performance drift (e.g., changes in resistance and capacitance decay), and external environmental corrosion (e.g., high temperature, high humidity, and dust adhesion affecting light path transmission). As a result, their actual light intensity will gradually deviate from the initial standard value. Therefore, it is necessary to periodically calibrate and adjust the light intensity of navigation lights to ensure aviation operational safety.

[0004] Currently, the mainstream method for adjusting navigation lights in the industry is offline disassembly and adjustment, and its specific operation process is as follows:

[0005] First, staff must use specialized tools to completely remove the navigation light to be adjusted from its mounting base, such as a runway edge light bracket or aircraft wing light mount, taking care to avoid damaging the light's housing and internal optical components. Second, the sealed housing of the navigation light is opened, and the core control circuit board is removed. This circuit board integrates a light intensity drive module and a current adjustment unit. Next, the circuit board is connected to external calibration equipment, such as a light intensity signal generator and a current calibrator, via a dedicated cable. The potentiometers or parameter configuration chips on the circuit board are gradually adjusted using the control signals output by these devices until the navigation light intensity reaches the preset target value. After adjustment, the light intensity output accuracy is checked again. Once confirmed to be acceptable, the circuit board is reinstalled into the navigation light housing and sealed. Finally, the navigation light is reinstalled back onto its original base, completing the entire adjustment process.

[0006] This traditional regulation method has significant limitations:

[0007] On the one hand, the entire process involves multiple disassembly and installation operations, which are cumbersome and require a high level of proficiency from the staff. Each adjustment is time-consuming, resulting in extremely low overall maintenance efficiency for scenarios such as airports that need to maintain a large number of navigation lights simultaneously. On the other hand, the disassembly process can easily damage the sealing structure of the navigation lights, leading to water and dust ingress issues during later use and shortening the lifespan of the navigation lights. At the same time, there are risks of electrostatic discharge and component detachment during the disassembly and handling of circuit boards, which may cause new equipment failures and further increase maintenance costs and safety hazards.

[0008] With the continuous growth of air traffic, the frequency of use and maintenance requirements of navigation lights are constantly increasing. Traditional offline disassembly and adjustment methods can no longer meet the needs of efficient and safe operation and maintenance. There is an urgent need to develop more convenient and reliable navigation light adjustment technology. Summary of the Invention

[0009] The present invention provides a navigation lighting emphasis adjustment system based on Bluetooth communication, which can effectively solve the problems in the background art.

[0010] This invention provides a navigation light intensity adjustment system based on Bluetooth communication, comprising:

[0011] The lamp has a driver module and a Bluetooth module inside. The driver module changes the light intensity by adjusting the output current, and the Bluetooth module communicates with the driver module.

[0012] And a terminal that controls the drive module to adjust the output current by communicating with the Bluetooth module;

[0013] It also includes a light intensity modulation method, comprising the following steps:

[0014] The actual luminous intensity of the lamp is measured by covering the lamp under test with a test lamp cover.

[0015] The terminal establishes a Bluetooth connection with the lamp under test and receives the initial light intensity value of the lamp through the Bluetooth module;

[0016] Adjust the initial light intensity value on the terminal to make the actual light intensity value of the lamp reach the target light intensity value.

[0017] As a further optimization of the present invention, it also includes an input current adjustment module connected to the lamp. The input current adjustment module adjusts the input current of the lamp, which is divided into five levels from high to low, corresponding to input currents of 6.6A, 5.2A, 4.1A, 3.4A and 2.8A respectively. The actual light intensity of the lamp is adjusted to the target light intensity by switching the input current level through the input current adjustment module.

[0018] As a further optimization of the present invention, when the lamp is white light, the corresponding input current adjustment module has five levels from high to low, and the drive module can adjust the light intensity ratio range to 1000‰, 169‰-313‰, 39‰-74‰, 10‰-21‰, and 2‰-7‰ respectively.

[0019] As a further optimization of the present invention, when the lamp is colored light, the corresponding input current adjustment module has five levels from high to low, and the drive module can adjust the light intensity ratio range to 1000‰, 168‰-398‰, 5‰-10‰, 12‰-30‰, and 2‰-17‰ respectively.

[0020] As a further optimization of the present invention, the terminal can obtain the lamp board temperature information, the current output current information of the driver module, and the factory identification information of the lamp through communication with the Bluetooth module.

[0021] As a further optimization of the present invention, the terminal can display the factory light intensity value set when the lamp leaves the factory.

[0022] As a further optimization of the present invention, the lamp is provided with a storage module for storing light intensity adjustment data and Bluetooth communication data with the terminal.

[0023] As a further optimization of the present invention, the light intensity tuning method also includes the following steps:

[0024] Input the actual light intensity value and the target light intensity value into the terminal, and the terminal will automatically compensate the initial light intensity value so that the actual light intensity value of the lamp reaches the target light intensity value.

[0025] As a further optimization of the present invention, the driving parameters of the terminal automatic compensation driving module are as follows:

[0026] P1 = (Target light intensity I) t X-drive module initial drive parameters P0) / current measured light intensity I0.

[0027] This invention provides a Bluetooth-based navigation light intensity adjustment system that can conveniently perform light intensity calibration. Using Bluetooth connectivity, the lights can be quickly calibrated to the target light intensity without disassembling the lights. This invention enables precise adjustment of the light intensity of the lights. Attached Figure Description

[0028] Figure 1 This is a diagram of the control steps in Example 1;

[0029] Figure 2 This is a screenshot of the terminal control interface in this embodiment. Detailed Implementation

[0030] Example 1

[0031] like Figure 1As shown, the lamp in this embodiment has a driver module and a Bluetooth module inside.

[0032] The driver module changes the light intensity of the lamp by adjusting the output current, and the Bluetooth module communicates with the driver module.

[0033] This embodiment also includes a terminal, which communicates with the Bluetooth module inside the lamp to control the drive module to adjust the output current, thereby controlling the light intensity of the lamp.

[0034] The driver module and Bluetooth module are installed inside the lamp at the factory. So when it is necessary to adjust the light intensity, you only need to establish a wireless connection between the terminal and the Bluetooth module in the lamp to adjust the light intensity without disassembling the lamp.

[0035] In this embodiment, each Bluetooth module in the lamp has a unique identity, namely the device number. The device number facilitates identification and record keeping.

[0036] Preferably, this embodiment also includes a storage module inside the lamp. The storage module can store light intensity adjustment data and data on the establishment of a communication connection between the terminal and Bluetooth, which is convenient for future retrieval.

[0037] like Figure 1 As shown, this embodiment also provides a method for adjusting the light intensity of a lamp, including the following steps:

[0038] The actual luminous intensity of a lamp is measured by covering it with a test lamp cover. The test lamp cover is a lamp cover with a built-in luminous intensity detector. The test lamp cover can shield the test data from interference from nearby lamps, so that only the luminous intensity of the lamp under test is measured.

[0039] The terminal approaches the light fixture under test, locates the Bluetooth device ID of the light fixture in the Bluetooth list, and establishes a connection. The terminal's display then shows the initial light intensity value of the light fixture sent by the Bluetooth module. For example... Figure 2 As shown, in this embodiment, the terminal is a mobile phone; in other embodiments, the terminal may also be a tablet computer or a laptop computer.

[0040] The initial light intensity value refers to the light intensity value set when the lamp under test was inspected at the factory or when the light intensity was last adjusted. As described in the background art of this application, lamps will experience aging, light decay and other conditions during long-term use, causing the actual light intensity of the lamp to deviate from the light intensity value set at that time. Therefore, the initial light intensity value data displayed on the terminal interface is unreliable.

[0041] However, the actual light intensity can still be adjusted by changing the initial light intensity value, so that the actual light intensity reaches the target light intensity value.

[0042] In this embodiment, the light intensity value adjusted on the terminal interface is actually achieved by adjusting the output current through the driver module, thereby changing the light intensity.

[0043] Preferably, a calibration operation can be set on the terminal interface to calibrate the light intensity value currently displayed on the terminal to the actual light intensity value.

[0044] The calibration method involves inputting the actual light intensity value and the target light intensity value into the terminal, and the terminal automatically compensates the initial light intensity value so that the actual light intensity value of the lamp reaches the target light intensity value.

[0045] The specific compensation method first involves constructing a coefficient k, which is obtained by the ratio of the actual light intensity I to the driving parameter P of the driving module. In this embodiment, the driving parameter of the driving module is mainly the output current.

[0046] Then we can calculate the coefficient k0 of the lamp at the factory: factory light intensity I0 / factory drive parameter P0.

[0047] According to the formula, when the driving parameter P remains constant, the smaller the k, the more severe the light intensity attenuation.

[0048] Then, the compensated driving parameters P1 are calculated.

[0049] By transforming the above formula, we can obtain:

[0050] After compensation, the driving parameter P1 = target light intensity I t / Attenuation coefficient k1.

[0051] The attenuation coefficient k1 is obtained as: actual light intensity I1 / factory drive parameter P0.

[0052] Combining and rearranging the two formulas, we get:

[0053] Compensated driving parameter P1 = (target light intensity I) t X (factory-defined driving parameters P0) / current measured light intensity I0.

[0054] The terminal can then automatically compensate for it with a single click, saving the effort of manual adjustment. Of course, the calculation method for this coefficient is not extremely precise, but it is sufficient for initial adjustment, and fine-tuning can be performed later if needed.

[0055] Furthermore, the terminal in this embodiment can also obtain information such as the lamp panel temperature, the current output current of the driver module, and the factory identification information of the lamp through communication with the Bluetooth module. This facilitates the understanding of detailed status information of the lamp itself during operation and allows for the establishment of alarm mechanisms. Once an abnormality occurs in the lamp, the system will immediately issue an alarm. This greatly shortens the troubleshooting time, improves maintenance efficiency, and ensures the stable operation of the airport navigation lighting system and flight safety.

[0056] Example 2

[0057] This embodiment adds a current adjustment module to the existing embodiment 1. The current adjustment module can adjust the input current of the lamp. The current adjustment module has five adjustment levels, corresponding to input currents of 6.6A, 5.2A, 4.1A, 3.4A, and 2.8A respectively. By switching between these input current levels using the current adjustment module, and then fine-tuning the light intensity at each level, the actual light intensity of the lamp can reach the target light intensity.

[0058] When the lamp is white light, the corresponding input current adjustment module has five levels from high to low. The drive module can adjust the light intensity ratios to 1000‰, 169‰-313‰, 39‰-74‰, 10‰-21‰, and 2‰-7‰, respectively. The adjustable light intensity ratio range of the drive module is the controllable range on the terminal.

[0059] When the light fixture is blue or red or other colored light, the corresponding input current adjustment module has five levels from high to low. The drive module can adjust the light intensity ratio range to 1000‰, 168‰-398‰, 5‰-10‰, 12‰-30‰, and 2‰-17‰ respectively.

[0060] This embodiment sets five levels of lamp input current, observes the light intensity of the lamp under each level, and then fine-tunes the light intensity under each level according to a set proportional range to achieve precise adjustment.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
