(iii) Operating conditions
1. During the construction of the structure, it shall be welded in the cast-in-place floor slab or prefabricated floor slab slab. According to the requirements of the radiometer, the prefabricated φ6~φ10 steel reinforced concrete boom shall be embedded. If there is no requirement, the steel beam shall be pre-assembled according to the arrangement position of the large keel. Rod, why the general spacing is 900~1200mm.
2. When the wall of a suspended ceiling room is a brickwork, the anticorrosive wood bricks shall be embedded along the walls and pillars at the elevation of the ceiling, and the distance between the walls shall be 900~1200mm. The columns shall not be buried on either side. Two or more wooden bricks.
3. Install all kinds of pipelines and ventilation ducts in the ceiling, and determine the lighting position, ventilation openings and various exposed hole locations.
4. All kinds of materials are fully equipped.
5. Wall and wet work projects should be completed before the ceiling cover panel is installed.
6. Set up a platform for the roof construction operation platform.
7.Before large-area frame roof construction, the light steel frame ceiling should be used as a model room. The degree of crowning of the ceiling, the construction of lamp channels and vents, and the method of blocking and fixing should be tested and approved before being approved. Area construction.

1. Welding prerequisite: (The solder joint must be at least 2mm away from the resin root)
Dip soldering: Please complete the soldering once within 5 seconds at 260°C to prevent the resin from being immersed in the tin bath.
Soldering iron: Use a 30W soldering iron with the tip temperature not higher than 350℃, and the soldering can be completed once within 5 seconds.
Do not apply external force to the product during soldering. Pay attention to prevent the LED pins from being corroded or discolored, otherwise it will cause soldering difficulties. It is recommended to use it as soon as possible.
2. Use attention:
Lead forming must be completed before soldering, and the spacing between the device holes on the circuit board should be consistent with the electrode pins.
If the product is cut under high temperature, it will be defective. Please cut the lead at room temperature.
Before the soldering temperature returns to normal, the LED must be protected from any vibration or external force.
3. Electrostatic protection:
In-line LED
High-brightness blue, green, and white products are sensitive to static electricity. Please be aware that the surge of static electricity will damage or destroy the product. Please use a conductive pad to ground the task table in contact with the product; the tip of the soldering iron must be grounded. To be grounded; it is recommended to use an ion generator.
4. Cleaning:
Special care must be taken when cleaning the gel with chemicals. Some chemicals can damage the surface of the gel and cause discoloration, such as trichloroethylene and acetone. It can be wiped and dipped in ethanol, and the time does not exceed 3 minutes at room temperature.
