Solar Low Intensity Type B

Product Specification

The solar aviation obstruction light like Flylight’s solar low intensity type B light can convert light energy into electrical energy and store it in the lithium iron phosphate battery through the controller. The lithium iron phosphate battery supplies the electrical energy to the control part. The light control sensor detects whether it is day or night and transmits the signal to the controller. The controller then Make a judgment. If the daytime controller does not give the LED driver signal, the LED driver does not work and the LED does not light up; if the night controller gives the corresponding signal to the LED driver, the LED driver works according to the controller signal and the LED turns on and off according to the control signal.

2. Detailed explanation of aviation obstruction light wiring

There are three ways to connect aviation obstruction lights, one is through signal line control, the other is through power modulation control, and the other is GPS synchronization.

(1) Signal line control method

a. The signal line controls the main and auxiliary lights synchronously: the number of cores of the aviation obstruction light signal line and flashing light cable is four cores, the brown wire and the black wire are the power wire, the blue wire is the signal wire, and the yellow-green wire is the ground wire; all For lamps that need to flash, connect all the wires of the same color in parallel, connect the yellow and green wires to the ground, and then connect the brown and black wires to the power supply. (See the manual for details)

b. The signal wire controls the connection between the controller and the light: when installing, connect the auxiliary light power cord and the controller's power cord in parallel, and the signal line in parallel with the controller's signal line. Connect the yellow and green wires to the controller after grounding. It can work normally after power on. (See the manual for details)

(2) Power modulation control method

a. Synchronous connection of the main and auxiliary lights of the power modulation: the main light cable outlet of the aviation obstruction light power link flashing is four-core, the brown wire and the black wire are the power wires, the blue wire is the power output wire, and the yellow-green wire is the ground wire; It is a three-core wire, the brown wire and the blue wire are the power wires, and the yellow and green wires are the ground wires; all the blue wires of the auxiliary lights that need to be flashed are connected in parallel with the blue wires of the main lights; the brown wires are connected with the brown wires of the main lights Parallel connection; after connecting the yellow and green wires to the ground, only need to power on the main light to work normally (see the manual for details)

b. Connection of power modulation controller control mode: When installing, connect the power cords of all auxiliary lights and the power cord output lines of the controller together; after grounding the yellow and green wires, power on the controller to work normally. (See the manual for details)

(3) GPS synchronization mode: Just select the appropriate power cord according to the actual power consumption of the lamp to connect to the corresponding power supply of the lamp. (Our new GPS synchronous flashing obstruction light adopts an advanced GPS timing system, which realizes a simple connection method under the premise of achieving synchronous work, and can realize synchronous flashing of all lamps and lanterns across the country).

How to choose an obstruction light bracket for aviation obstruction lights?

Aviation obstruction lights need to be fixed on obstacles through an aviation obstruction light mounting bracket, instead of simply locking the aviation obstruction lights on the concrete roof or the parapet and other materials.

Aviation obstruction light brackets need to be designed based on the construction environment on site and the material reference of the installation objects. It is impossible to achieve an obstruction light bracket that is suitable for all obstacles. Therefore, after determining the choice of aviation obstruction lights, it is necessary to provide relevant CAD design drawings (generally elevation, node and top views) of the obstacle site. Based on the provided drawings, the relevant technicians can design an applicable Obstruction light bracket.

Aviation obstruction light brackets can be divided into vertical mounting brackets. Vertical mounting brackets are more commonly used, and are mostly suitable for installing aviation obstruction lights on the top/vertex. Side wall mounting brackets are mostly suitable for aviation obstruction lights to be installed on external walls. Hoop-type mounting brackets are mostly suitable for chimneys, cooling towers and other fences, and platform guardrails on cylindrical obstacles.

Before purchasing solar low intensity type B light, we must first determine the height of the installation location of aviation obstruction lights. According to relevant national regulations, aviation obstruction lights used at different heights have different light intensity, light color, and flashing frequency. In order to avoid aviation obstruction lights Purchase error, Shenzhen Shiluda Technology Co., Ltd. briefly introduces the different types of solar high-altitude obstacle warning lights, solar aviation obstacle lights installation distance range:

Solar aviation obstruction lights are generally divided into low intensity, medium intensity and high intensity. The vertical and horizontal distances of aviation obstruction lights are greater than 45 meters for buildings and their facilities, and the three types of obstruction marker lights can be used in conjunction with each other. Aviation obstacle indicator classification

Below 45 meters above the ground, low-intensity aviation obstruction lights should be set up in relatively open surroundings, which are always bright red.

Buildings and facilities 45 meters above the ground and 105 meters below the ground: use medium-intensity type B aviation obstruction lights as red flashes, flashing frequency between 20-60 times per minute, and effective light intensity of 2000cd ± 25%.

Use medium-intensity A-type aviation obstruction lights above 105 meters above the ground and below 150 meters; white flashing, effective light intensity (2000-20000cd) ± 25%.

For buildings and facilities above 150 meters from the ground, use high-intensity solar high-altitude obstacle warning lights and must be white flashing lights. The flash frequency should be between 20-70 times per minute. The effective light intensity depends on the background brightness. It works 24 hours a day.

 Backgroud knowledge:

Aviation obstruction light lightning protection measures-obstruction light lightning rod:

When the rainy season approaches, the probability of aviation obstruction lights being struck by lightning will increase, especially the obstruction lights installed on the top floor. During the installation and design of aviation obstruction lights, the lightning protection facilities and lightning protection methods of aviation obstruction lights will be considered in advance. Aviation obstruction light lightning rod is a simple measure for aviation obstruction light to protect from lightning.

 The lightning rod is to erect a conductive needle on the mounting bracket of the aviation obstruction light, and the height of the needle should be higher than the overall height of the lamp. The needle should have super high conductivity or conductivity, and connect the needle with the installation bracket and the overall lightning protection facilities of the building. Therefore, when the lightning strikes the position of the obstruction light, the lightning rod at the height will distract the lightning and lead it to the ground of the building. So as to avoid the phenomenon of lightning damage to the lamps.

Obstacle light lightning rods can avoid small and medium lightning strikes. For large lightning strikes, professional lightning protection facilities are needed to avoid them. Because the lightning rod can withstand a certain range of lightning strike intensity. In areas where lightning strikes frequently occur, a professional lightning protection system needs to be set up at the top level, taking into account the lightning protection of aviation obstruction lights.

 Aviation obstruction lights are installed in high-rise locations and need to withstand severe weather conditions such as high temperature, low temperature, high wind pressure, and lightning strikes under certain conditions. Therefore, the Civil Aviation Administration of China issued a new test specification for aviation obstruction lights AC-137-CA-2017-05 "Aviation Obstruction Light Inspection Specification", which clearly defines the requirements for the use environment of aviation obstruction lights. Only the aviation obstruction lights that have passed the full inspection of the new inspection specifications and obtained the CAAC net notice can they be allowed to be sold in the market, and then they can pass the acceptance by the civil aviation or military aviation related departments.
