皇家蓝色发光二极管:解码数据表
白光LED是由钇铝石榴石(YAG)荧光粉与蓝光LED一起工作而发出的白光,是许多照明设备的核心技术。然而,另一种被称为远程荧光粉的技术正在取得进展,因为它具有更高的功效。
与白光LED类似,这项技术使用了一种蓝色蓝色LED作为光子泵,但它不是将LED和荧光粉组合成一个包,而是通过分离这两个关键组件来获得优势。
这确实使设计过程复杂化了,因为工程师不需要从单个供应商那里指定一个集成的led /荧光包,工程师现在不得不考虑两个不同的部分。
Furthermore, engineers familiar with white LEDs are used to drawing comparisons between devices by considering parameters such as luminous flux (in lumens — lm) and efficacy (lumens/watt — lm/W)。 Nevertheless, comparing discrete royal blue LEDs is different; manufacturers have historically specified the LEDs’ radiant flux (in milliwatts — mW) instead of luminosity, and efficacy has given way to efficiency (in milliwatts/W —mW/W)。
This arTIcle decodes the datasheet for royal blue LEDs by explaining the key parameters that should be considered when choosing an LED for a remote phosphor applicaTIon.
