Intematix today announced an LED lighting component designed to improve LED efficiency and give lighting manufacturers more design flexibility.
The Fremont, Calif.-based company announced its ChromaLit product line, a phosphor which converts the blue light of LED light sources into pleasing white light.
Phosphors, which are used on all LED light fixtures and bulbs, are often directly coated onto LED light sources, the semiconductors which emit light when electricity is passed through them. By contrast, the disk-shaped ChromaLit is a separate component. That allows for LED light fixtures with more possible shapes, including three-dimensional and curved LED light fixtures, according to Intematix.
A separate phosphor is also up to 30 percent more energy efficient and manufacturers can swap in different phosphors on the same LED light source to create products with different color temperature and color rendering index.
Having a separate phosphor can extend the life and performance of LEDs, Intematix CEO Mark Swoboda told Scientific American. Phosphors coated onto an LED light source often reflect much of the light back toward the semiconductor light source, but a layered design means that reflected light can still be emitted around the sides of the phosphor disk.
The company is targeting ChromaLit at LED light fixture manufacturers in both the commercial and the residential market.
