Introduction to the Current of 0402LED Lamp Beads

1. 0402 Lighting Delite 0.06W Plug in the normal working current of LED lamp beads is 20mA, and the normal working current of 0.2WLED lamp beads is 60mA 2. Overcurrent maintenance: The current is too large to attract direct LED lamp bead dead lamps, and the brightness accelerates attenuation attenuation. In the circuit design, according to the voltage drop of LED lamp beads, different current limiting resistors are paired with different current resistance to stop series maintenance to ensure the normal work of the LED lamp beads to reach a better working state state. 3. LED lamp beads with the same power should work under the same current conditions. If the current is too large, the life of LED lamp beads will be shortened, and the current is too small to reach the required light intensity. 0402LED lamp beads brightness test and product clarification 1. When using LED lamp beads with split -split -split color, please use them according to different BIN levels. Different levels of BIN -class products cannot be used to use the same product, which causes product differences to poor differences. If you really need to use a mixed BIN level, you can use the adjacent BIN level together, but you should prevent it as much as possible. 2. When testing VF, brightness and wavelength, the normal working current should be set according to the practical power of LED lamp beads. When testing VR, set the IR to 10UA, and when testing IR, set the VR to 5V. When testing and using LED lamp beads, the same current must be provided for each LED lamp bead, that is, using constant current detection to ensure the same brightness. 0402LED lamp beads Anti -static Electricity Pay attention to matters 1. The operator must wear anti -static gloves and anti -static wristbands, and ensure good grounding. Before touching LED lamp beads, please perform static electricity consumption work. Electric soldering iron or soaked welding equipment must be grounded, and ionic fans should be used to dispel electrostatic electricity. Do not touch the two pins of LED lamp beads naked. 2. Static and waves can damage LED lamp beads. 3. All equipment, instruments and working appearances that are in contact with LED lamp beads must be equipped with ground wires, and special soldering iron and tin furnaces must be well grounded; measure.
