LED semiconductors as the entire light-emitting diode, made of semiconductor materials to directly convert electrical energy into light energy, electricity, convert the optical signal devices; and characterized by low power consumption, high brightness, colorful, anti-vibration, life the advantages of long (normal luminous 80,000-100,000 hours), cold light source, is the real "green lighting." LED light source for lighting products in the 21st century will inevitably replace the white lights woven into human lighting another revolution.
Next, the light-emitting diodes led manufacturers to expand introduce several ways on how to save and use LED lights beads:
1. Save
(1) In order to moisture, LED should be stored in dry and ventilated environment, storage temperature is -40 ? - + 100 ?, relative humidity below 85%. ?
(2) led Ends in its original packaging conditions within three months is better to avoid the bracket rust.?
(3) When the bags led Kaifeng, to finish as soon as possible, when the storage temperature is 5 ? -30 ?, relative humidity below 60%.
2. Clean
(1) Do not use an unknown chemical liquid cleaning LED, LED because that may damage the surface of the resin, and even cause cracks colloid and, if necessary, at room temperature, the LED immersed in alcohol or fluorine wrapped in expensive cleaning time in one minute Inside.
3. Forming ?
(1) Do not welded during welding or after shaping, if necessary, must be shaped before completion of welding.?
(2) Keep in mind that any act extruded resin are likely to damage the internal LED golden thread.
4. Welding ?
(1) in the welding process, do not apply to any external pressure lamp body, otherwise the LED internal cracks may appear, it will affect its internal gold wire caused by quality problems. ?
(2) must not be immersed in the solder into the colloid. ?
(3) welding, soldering points from the next colloid along at least a gap of 2 mm, welding is completed, it is necessary to use three minutes to let the LED back from a high temperature state at room temperature. ?
(4) If the same PCB with the soldering iron linear array of LED, LED Do not weld the same two pins. ?
(5) soldering iron 30W with the following requirements when welding.?
(6) LED welding in two sizes, specific parameters are as follows: soldering iron temperature: 295 ? ± 5 ?
(7) Soldering time: 3 seconds or less (once only)?
(8) Wave soldering temperature: 235 ? ± 5 ?
(9) welding time: 3 seconds or less ?
Description: welding temperature or time control incorrectly, you may cause LED lens distortion or open lead wick inside dead lights.
