Application of high temperature resistant terminal wire in LED lighting
With the wide application of energy-saving lamps, in order to ensure the quality and safety of lighting, in addition to the hardware quality of the lighting itself, we should also pay attention to the quality of the lighting and power connection wires. The application of high temperature resistant terminal wire harnesses in LED and other lighting also conforms to the general trend.As a result of the lighting work process will produce high temperature. Ordinary connectors have extremely limited resistance to high temperatures. The high-temperature terminal wires can continue to work in the high temperature environment of 200 ℃ for a long time. It is suitable for installation in electrical circuits with high-temperature AC rated voltage 600V connection.
For high-power energy-saving lighting products, first of all, the light source material of the product itself must use three primary colors, and cannot use mixed powder or halogen powder; for those substandard PC plastic shells, temperature and pressure resistant materials, not environmentally friendly materials, high quality products are impossible to use.
Secondly, the induction coil must be soaked in high-temperature insulating paint, and the magnetic ring and the magnetic ring wire must be sprayed with high-temperature insulating paint. Should use high temperature resistant terminal wire harness, such as UL3239 high temperature resistant silicone terminal wire.
Third, the test conditions must start at low temperature and low pressure, high temperature and high pressure aging, low temperature test temperature is below -25 ℃, high temperature test temperature should be higher than 150 ℃, high voltage test voltage is greater than 280V.
Fourth, the high temperature and high pressure impact electronic components guarantee 100% safety. The test parameters are as follows: resistance withstand voltage ≥400V, temperature withstand temperature ≥150℃, diode withstand voltage ≥1400V, triode must be matched and tested, capacitor temperature withstand temperature ≥150℃, electrolysis temperature resistance ≥125℃, core temperature ≥200℃.
