常见问题 | LED
LED 是否适用于车载用途？
采用带有密封盖的封装的 LED 适合在高温高湿环境中使用。请联系我们的销售办事处，了解配有密封盖的产品的相关信息。树脂灌封封装由于其温度循环耐久性差，不适合车载用途。
LED 辐射通量能否转换为辐射强度或辐射照度？
辐射通量是汇集的向各个方向发射的光总量。另一方面，辐射强度和辐射照度是沿着光轴的小片区域测量的，所以会受发光指向性影响。因此，LED 辐射通量不能转换为辐射强度和辐射照度。
你们如何确定 LED 的使用寿命？
寿命结束是指光输出降至初始值 50% 的时候。
激光器是根据其输出功率进行分类的。LED 是否也要这样分类？
不，LED 不像激光器那样分类。

1. What are cookies?
For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently.
