1. The working current of straw hat LED lamp beads 1. The normal working current of 0.06W straw hat LED lamp beads is 20mA, and the normal working current of 0.2W straw hat LED lamp beads is 60mA. 2. Over-current protection: Excessive current will cause the LED lamp bead to die and the brightness to accelerate attenuation. In the circuit design, different current limiting resistors should be paired with different current-limiting resistors for series protection according to the voltage drop of the LED lamp beads to ensure the normal operation of the LED lamp beads to achieve the best working state. 3. The straw hat LED lamp beads of the same power should work under the same current conditions. If the current is too large, the life of the LED lamp beads will be shortened. If the current is too small, the required light intensity cannot be achieved. 5mm straw hat white hair red.jpg 2. Brightness test and product instructions 1. When testing VF, brightness, and wavelength, the normal working current should be set according to the actual power of the LED lamp beads. When testing VR, the IR is set to 10uA, and when testing IR, the VR is set to 5V. . When testing and using straw hat LED lamp beads, each LED lamp bead must be provided with the same current, that is, constant current detection is used to ensure the consistent brightness of the measurement. 2. When using straw hat LED lamp beads that have been divided into light and color, please use them according to different BIN grades. Different grades of BIN grade products cannot be mixed and used on the same product, resulting in poor product consistency. If you really want to use mixed BIN levels, adjacent BIN levels can be used together, but should be avoided as much as possible. 3. Anti-static precautions 1. Static electricity and surge voltage will damage the straw hat LED lamp beads. 2. All equipment and instruments that contact the LED lamp beads, and work surfaces must be equipped with a ground wire, and the soldering iron and tin furnace must be grounded. Good; there should be anti-surge voltage measures in the equipment using LED lamp beads. 3. The operator must wear anti-static gloves and anti-static wristbands and ensure good grounding. Before touching the LED lamp beads, perform static elimination work. The electric soldering iron or dip soldering equipment must be grounded. At the same time, an ion fan should be used to eliminate static electricity. It is strictly forbidden to touch the two pins of the straw hat LED lamp with bare hands. 4. The anti-static bracelet must be tested every day, and the unqualified ones must be replaced. 4. Welding conditions 1. The LED lamp beads cannot be energized during welding. 2. When soldering with a soldering iron: the maximum power of the soldering iron is 30W, the highest temperature of the soldering iron tip: 280℃, the longest preheating time is 60S, the longest soldering time should not exceed 3S; when using dip soldering, the highest temperature should not exceed 260℃, the longest time Must not exceed 5S. 3. Soldering iron position: more than 4mm away from the bottom of the colloid; dip soldering position: more than 3mm from the bottom of the colloid. 4. During welding or heating, before the temperature returns to normal, it is necessary to avoid any vibration or external force applied to the LED. It is recommended to use a fixture to fix the welding. Fifth, because of the design needs to bend or cut the pin forming method 1. When bending and cutting the straw hat LED lamp bead, the position of the bent foot and the cut foot should be at least more than 2mm from the bottom surface of the gel, otherwise it will cause the straw hat LED lamp bead colloid breaks and damages the internal structure. 2. Bracket molding must be done with fixtures or by professionals. 3. The support forming should be completed before welding. 4. When forming the bracket, ensure that the pins and spacing are consistent with the spacing of the holes on the circuit board. 5. When cutting the feet, the vibration and friction of the cutting machine will generate high voltage static electricity, so the machine must be reliably grounded and anti-static work. 6. How to install the straw hat LED lamp beads 1. Pay attention to the lead arrangement of the straw hat LED lamp beads. In case the polarity is incorrectly installed during use. The LED lamp bead should not be too close to the heating element, and the working conditions should not exceed its prescribed limits. 2. Please do not install LED lamp beads when the pins are deformed. 7. Working and storage temperature of straw hat LED lamp beads. The working temperature of straw hat LED lamp beads is -30℃～60℃, and the storage temperature is -40℃～85℃. When energized, avoid high-temperature operations above 60°C. If high-temperature operations occur, heat dissipation protection measures must be taken.
