10 / 10 page 10 2、Storage(储存) ☆M oisture proof and anti -electrostatic package with moisture absorbent material is used,to keep moisture to a minimum. Before opening the package, the product should be kept at 30℃ or less and humidity less than 60%RH,and be used whthin six months. 本产品使用密封防潮搞静电袋包装,并附有干燥剂,以保证产品不会吸潮 ,产品包装在开封前,产品须放在温度不高 于 30℃,湿度不高于 60%RH 的环境中。 ☆ After opening the package,the product should be stored at 30℃or less and humidity less than 10%RH,and be soldered within 24 hours.It is recommended that the product be operated at the workshop condition of 30℃or less and humidity less than 60%RH 产品包装开封后,产品必须储存在温度不高于 30℃,湿度不高于 10%RH 的环境中,且应该在 24 小时内使用完, 建议工作环境为温度不高于 30℃,湿度不高于 60%RH。 ☆ If the moisture absorbent material has fade away or the LEDs have exceeded the storage time,baking treatment should be performed based on the following condition(75±5) ℃ for 24 hour。 对于尚未焊接的LED,如果吸湿材料或包装失效,或者产品没有符合以上有效储存条件,烘烤可以起到一定的性 能恢复效果,烘烤条件: 75±5 ℃,持续 24 小时。 3、Static electricity(静电防护) ☆ Static electricity or surge voltage damages the LEDs.Damaged LEDs will show some unusual characteristic such as the forward voltage gecomes lower,or the LEDs do not light at the low current.even not light. All devices,equipment and machinery must be properly grounded.At the same time,it is recommended that wrist bands or anti-electrostatic gloves,anti-electrostatic containers be used when dealing with the LEDs. 静电或电涌会导致产品特性发生改变,例如正向电压降低,如果情况严重甚至会损毁产品,所以在使用时必须采取 有效的防静电措施;所有相关的设备和机器都应该正确接地,同时必须采取其他防止静电和电涌的措施,使用静电 手环,防静电垫子,防静电工作服,工作鞋,手套,防静电容器,都是有效的防止静电和电涌的措施。 4、Vulcanization(硫化) ☆ LED curing is due to sulfur being in bracket and the +1 price of silver in the chemical reaction generated Ag2S in the process.It will lead to the capacity of reflecting of silver layer reducing, light color temperature drift and serious decline, Seriously affecting the performance of the product. So we should take corresponding measures to avoiding vulcanization, Such as to avoid using sulphur volatile substances and keeping away from high sulphur content of the material. LED 硫化是由于环境中的硫进入支架内部与+1 价的银发生化学反应生成黑色 Ag2S 的过程。该过程会导致支架镀银 层的反光能力下降,色温漂移和光衰严重,很大程度上影响了产品性能。因此,在使用时应注意采取相应的防硫措 施,如避免使用挥发性强的含硫物质,避免接触含硫较高的物质。 5、Safety advice for human eyes(眼睛防护) ☆ Viewing direct to the light emitting center of the LEDs,especially those of great Lumious Intensity will cause great hazard to human eyes.Please be careful. LED 发光时,请勿直视发光光源,特别是对于一些光强较高的 LED,强光可能伤害你的眼睛。 6、Design consideration(设计建议) ☆ In designing a circuit about LED,the current through each LED must not exceed the absolute maximum rating specified for each LED. In the meanwhile,resistors for protection should be applied,otherwise slight voltage shift will cause big current change,burn out may happen. 设计带有 LED 产品的电路时,通过 LED 的电流不能超过规定的最大值,同时还需使用保护电阻,否则微小的电压变 化将会引起较大的电流变化,可能导致产品损毁。 深圳市永而佳电子有限公司 ECELTRONIC CO., LTD SMD |
