Nichia is a Japanese LED company. Their low powered LED's are still used in some flashlights. | Nichia is a Japanese LED company. Their low powered LED's are still used in some flashlights. | ||
For high power LED's the Nichia chromaticity binning codes are now based on [[ANSI White]] quadrants. A bin of SW50 is an ANSI quadrangle of 5000K. The NVSSW119A and NVSW219A series LED's are similar to the [[Cree]] XP-G and available up to a B14 bin. The NVSW119A-H3 and NVSW219A-H3 have a neutral tint of 5000K and have a maximum flux bin of B12. The warmer high [[Terminology#CRI|CRI]] NVSL119A-H1 and NVSL219A-H1 have a maximum flux of B10 | For high power LED's the Nichia chromaticity binning codes are now based on [[ANSI White]] quadrants. A bin of SW50 is an ANSI quadrangle of 5000K (SW45 is 4500K and so on). Forward voltage bins are L (2.7-3.1V) and M (3.1-3.5V). | ||
The difference between the 119 and 219 series seems to be the layout of solder pads on the bottom of the LED. The NVSSW119A and NVSW219A series LED's are similar to the [[Cree]] XP-G and available up to a B14 flux bin. The NVSW119A-H3 and NVSW219A-H3 have a neutral tint of 5000K and have a maximum flux bin of B12. The warmer high [[Terminology#CRI|CRI]] NVSL119A-H1 and NVSL219A-H1 have a maximum flux of B10. | |||
