Home > Product Lines > Phosphor
- Phosphor absorbs diverse types of energy like light, X-ray, Ultra violet, electric field. In the mean while, phosphor is
  emitting energy in the range of visible ray with some of the absorbed energy by the according energy level.
- White LED light is applicable by using blue LED chip with green, yellow, or red phosphor.
