We optimized the after-disposing technology and found an effect ball-grinding way to make the granularity of BAM blue phosphor decline under the condition of keeping the high comparative brightness.

对后处理工艺进行了优化，通过弱球磨，有效地降低了BAM蓝粉的粒度，同时相对亮度没有明显降低。

Philips' solution is to combine two blue and one red element, but use a green phosphor filter to convert one of the blue LEDs to green.

ENGADGET

Generally LED bulbs use either a combination red, green and blue LEDs to create white light, or they use a phosphor coating (more common) in combination with a blue LED.

ENGADGET

These can be made to emit white light by coating the device with a phosphor compound that absorbs part of the blue light and re-emits it as yellow.
