3. 硫化:
Vulcanization
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。
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 avioding
vulcanization, such as to avoid using sulphur volatile substances and keeping away from high sulphur content of the
material.
4. 眼睛保护忠告:
Safety Advice For Human Eyes
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。
Viewing direct to the light emitting center of the LEDs, especially those of great Luminous Intensity will cause great
hazard to human eyes. Please be careful.
5. 设计建议:
Design Consideration
设计电路时,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。
建议使用以下(A)电路,该电路能够很好的调节通过每个 LED 的电流;不推荐使用(B)电路,该电路
在持续的电压驱动下,LED 的正向电压(VF)发生变化,电流会随之而发生变化,可能使某些 LED 承受高于
规定的电流值。
In designing a circuit, 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.
It is recommended to use Circuit A which regulates the current flowing through each LED rather than Circuit B.
When driving LEDs with a constant voltage in Circuit B, the current through the LEDs may vary due to the variation
in Forward Voltage (VF) of the LEDs. In the worst case, some LED may be subjected to stresses in excess of the
Absolute Maximum Rating.
