Nichia NVSW219F Light Emitting Diode (LED)
Improved 2W 3535 white LED offers higher flux and efficacy
Nichia has launched the NVSW219F, a new 2W white LED for lighting applications which gives higher light intensity and efficacy than previous versions.
The Nichia NVSW219F, a domed LED which has a 3.5mm x 3.5mm board footprint, is supplied in multiple CCT versions: 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K and 6500K.
The 5000K LED, specified with a minimum color rendering index rating of 70, produces a typical light output of 346lm at a drive current of 700mA. This is 7% higher than the light output from the previous NVSW219C. The NVSW219F’s efficacy of 167lm/W is 8% better than that of the NVSW219C. The typical forward voltage of the NVSW219F is 2.96V, another slight improvement.
As its predecessor does, the Nichia NVSW219F uses an aluminum nitride substrate, helping yield industry-leading lifetime at up to a maximum junction temperature of 150°C. The new LED also offers better color-over-angle performance than competing 3535 2W-class LEDs, optimizing optical performance.
