Choosing the quality of LED lamps is a very important factor. Different packaging processes can have a significant impact on product quality. Compared to LED lamps packaged with Class A low attenuation adhesive, LED lamps packaged with ordinary primer have a 76% reduction in light attenuation under the same aging environment. Therefore, selecting LED lamps with good packaging technology will greatly extend their service life.
To prevent moisture, LEDs should be stored in a dry and ventilated environment with a storage temperature of - 40 ° C-100 ° C and a relative humidity of less than 85%. It is best to use the original packaging LED within 3 months to avoid rust on the bracket. After the LED packaging bag is opened, it should be used up as soon as possible. At this time, the storage temperature is 5 ℃ - 30 ℃, and the relative humidity is below 60%.
Do not use unknown chemical liquids to clean LEDs, as they may damage the LED resin surface and even cause colloidal cracks. If necessary, immerse the LED in alcohol or fluorine at room temperature and clean it within one minute.
During welding, do not apply any external pressure to the lamp body, otherwise cracks may appear inside the LED, affecting its internal gold wire connection, causing quality problems. The colloid must not be immersed in the solder. During welding, there should be a gap of at least 2mm between the solder joint and the lower edge of the colloid. After welding, it takes three minutes for the LED to recover from the high-temperature state to the normal temperature state. If you use a soldering iron to weld linear LEDs on the same PCB, do not weld two pins of the same LED at the same time. When welding with a soldering iron, a soldering iron below 30W is required.
During or after welding, it is not allowed to form. If necessary, it must be formed before welding. Please remember that any action to squeeze the resin can damage the gold wire inside the LED.
