Japanese chemical engineering and manufacturing company, headquartered in Tokushima, Japan. Specializes in the manufacturing and distribution of phosphors, including light-emitting diodes (LEDs), battery materials, and calcium chloride.
Light Emitting Diode – InGan LED NICHIA
Nichia 219 white LED offers typical 140 lumen output at 1 W input power with 5,000 K color temperature. Using a uniformly phosphor coated chip, Nichia 219 has the industry leading source brightness and tightest optical footprint.
High Power Point Source White Led NVSx219AWe rolled out a better idea
The spatial color uniformity is also optimized with Nichia’s leading phosphor technology. At 350 mA drive current, the typical forward voltage is only 3.0 V. Additionally, this package is capable of drive currents up to 1.5 A.
