Publish Time: 2024-08-29
Safety precautions for Led Direct Plug-In Lamp Beads mainly cover anti-static treatment, correct use, proper storage, and compliance with general safety requirements for LED lamps. The following are detailed precautions:1. Anti-static treatmentWear anti-static equipment: All operators must wear anti-static gloves and anti-static wristbands to prevent static electricity from damaging LED lamp beads. Anti-static wristbands should be tested daily to ensure their effectiveness and should be replaced in time if they fail.Grounding and ion fans: The ferrite, dip soldering equipment, operating table, storage rack, etc. must be grounded to eliminate static electricity. At the same time, ion fans can be used to further reduce the static electricity level in the environment.Avoid bare-hand touch: It is strictly forbidden to touch the two pins of the LED with bare hands, especially when the working humidity of the workbench is 60%-90%, because the static electricity of the human body may damage the crystal layer of the direct plug-in LED.2. Correct usePin forming: When bending the bracket, it is necessary to ensure a distance of at least 2 mm from the colloid, and the bracket forming must be completed before welding. The pins and spacing must be consistent with the circuit board.Bend and cut the feet: The position of the bend and cut feet should be greater than 3mm from the bottom surface of the colloid, and the bend should be performed before welding. When cutting the feet, since the cutting machine may generate high-voltage static electricity, the machine should be firmly grounded and anti-static work should be done.Welding conditions: When using a soldering iron to solder, the top temperature of the soldering iron should not exceed 300℃, the soldering time should not exceed 3 seconds, and the soldering position should be at least 2 mm away from the colloid.Cleaning precautions: Be particularly careful when cleaning the colloid with chemicals, and avoid using chemicals that may damage the surface of the colloid, such as trichloroethylene, acetone, etc. Ethanol can be used for scrubbing or dipping, but the time should not exceed 3 minutes.Overcurrent protection: To prevent LED overcurrent damage, a protective resistor can be connected in series, and the resistance value should be calculated based on the power supply, LED drive voltage and forward current.3. Proper storageEnvironmental conditions: LED direct plug-in lamp beads should be stored in an environment with a temperature below 30℃ and a relative humidity below 60% to prevent moisture absorption and increase the probability of dead lamps.Packaging and sealing: LED lamp beads must be packaged in anti-static bags and re-sealed for storage after opening the anti-static packaging to maintain their anti-static properties.Environmental cleanliness: Pay attention to the cleanliness of the storage environment to avoid discoloration caused by contact between the surface of the LED lamp bead pins and chemicals or gases.4. Comply with general safety requirements for LED lampsLabeling and inspection: LED lamp products must be 100% inspected before leaving the factory, including the accuracy of information such as labeling, rated voltage, frequency, power, color temperature, etc.Anti-electric shock protection: LED lamps should be designed and manufactured so that they can work safely during normal use and do not cause harm to people or the surrounding environment. According to the type of lamp (such as Class I, Class II, Class III), take appropriate anti-electric shock protection measures.Grounding continuity: For lamps that require grounding protection, grounding continuity and reliability should be ensured, and the grounding resistance should meet the requirements of relevant standards.The safety precautions for Led Direct Plug-In Lamp Beads involve anti-static treatment, correct use, proper storage, and compliance with general safety requirements for LED lamps. Through the implementation of these measures, the safety risks of LED plug-in lamp beads during use and storage can be effectively reduced.
